RESUMO

RESUMEN Introducción: la pandemia por COVID-19 presentó desafíos a nivel mundial. La aceptación de las vacunas en la población es indispensable como medida preventiva. Es innegable que existen factores que elevan el rechazo o cuestionamiento al respecto, que pueden estar relacionados con la cultura, política, confianza, conveniencia, experiencia en servicios sanitarios, también la opinión del entorno. Objetivo: determinar el porcentaje de estudiantes y docentes vacunados, y el número de dosis aplicadas contra el COVID-19 de la Facultad de Odontología de la Universidad Nacional de Asunción, en el año 2022. Metodología: estudio observacional descriptivo de corte transversal, aplicando una encuesta en digital con 23 preguntas acerca del conocimiento, aplicación y autopercepción de la vacuna; además de datos demográficos. Resultados: fueron incluidos 168 encuestados, 128 estudiantes y 40 docentes. 80,0 % fueron mujeres. 97,6 % se ha vacunado contra COVID-19, la mayoría (85,4 %) se aplicó tres dosis de la vacuna. 34,1 % se aplicó la vacuna Covaxin, 32,9 % Sputnik V, 15,9 % AstraZeneca y 17,1 % otras (Pfizer, Sinopharm y Moderna). El 35,1 % tuvo dudas acerca de la eficacia pero que en su mayoría se aplicaron igualmente. El 94,1 % consideró necesaria y el 88,7 % segura la vacuna. El 78,5 % respondió que la cobertura es elevada para prevenir los síntomas de la enfermedad. El 35,1 % mencionó sentirse protegido en su totalidad con la vacuna. El 78,6 % sabe que puede presentarse luego de la aplicación alguna reacción adversa. Conclusión: casi la totalidad de los encuestados se encontraban vacunados y se aplicaron las tres dosis de la vacuna COVID-19 al momento de la encuesta.

ABSTRACT Introduction: the COVID-19 pandemic presented challenges worldwide. The acceptance of vaccines in the population is essential as a preventive measure. It is undeniable that there are factors that increase rejection or questioning in this regard, which may be related to culture, politics, trust, convenience, experience in health services, and also the opinion of the environment. Objective: to determine the percentage of students and teachers vaccinated, and the number of doses applied against COVID-19 in Facultad de Odontología at the Universidad Nacional de Asunción, in the year 2022. Methodology: cross-sectional descriptive observational study, applying a digital survey with 23 questions about knowledge, application and self-perception of the vaccine; in addition to demographic data. Results: 168 respondents were included, 128 students and 40 teachers. 80.0 % were women. 97.6 % have been vaccinated against COVID-19, the majority (85.4 %) received three doses of the vaccine. 34.1 % received the Covaxin vaccine, 32.9 % Sputnik V, 15.9 % AstraZeneca and 17.1 % others (Pfizer, Sinopharm and Moderna). 35.1 % had doubts about the effectiveness but most of them were applied anyway. 94.1 % considered the vaccine necessary and 88.7 % safe. 78.5 % responded that coverage is high to prevent the symptoms of the disease. 35.1% mentioned feeling fully protected with the vaccine. 78.6% know that some adverse reaction may occur after application. Conclusion: almost all of the respondents were vaccinated and had received all three doses of the COVID-19 vaccine at the time of the survey.

RESUMO

O objetivo desse estudo foi descrever o comportamento do indicador de proporção de gestantes com atendimento odontológico realizado em todos os estados brasileiros antes e após a implantação do Programa Previne Brasil e correlacionando os achados com variáveis. Trata-se de um estudo ecológico, analítico, com dados secundários, cujas unidades de análise são 26 as unidades federativas do Brasil e o Distrito Federal. As variáveis proporção de gestantes com atendimento odontológico realizado entre os anos de 2018 e 2022 (por quadrimestre), número de equipes de Estratégia de Saúde da Família, cobertura de eSF e cobertura da Atenção Básica (AB) no ano de 2020, número de equipes da saúde da família de saúde bucal (eSB) no ano de 2021, tamanho populacional estimado para 2021 e Índice de Desenvolvimento Humano para o ano de 2010, foram coletadas do Sistema de Informação da Saúde da Atenção Básica (SISAB), do Instituto Brasileiro de Geografia e Estatística (IBGE) e do Sistema e-Gestor do Ministério da Saúde. Os resultados obtidos mostram que durante os anos analisados o indicador teve crescimento em todas as unidades federativas e no Distrito Federal, no entanto alguns estados tiveram crescimento do indicador acima da média nacional: Amazonas, Tocantins, Alagoas, Ceará, Paraíba, Pernambuco, Rio Grande do Norte, Sergipe, Mato Grosso do Sul Paraná e Santa Catarina. O indicador teve correlação negativa com IDH e positiva com as coberturas de equipes de saúde da família e de saúde bucal. Houve um aumento na proporção de atendimentos odontológicos a gestantes na APS entre os anos estudados, no entanto, esse indicador não permite a avaliação da qualidade desse atendimento e nem o impacto na morbimortalidade materna e infantil.

The aim of this study was to describe the behavior of the indicator of the proportion of pregnant women with dental care performed in all Brazilian states before and after the implementation of the Prevent Brazil Program and correlate the findings with variables. This is an ecological, analytical study with secondary data, whose units of analysis are 26 of the federative units of Brazil and the Federal District. The variables proportion of pregnant women with dental care performed between the years 2018 and 2022 (per four months), number of Family Health Strategy teams, FHS coverage and Primary Care (PHC) coverage in 2020, number of oral health family health teams (eSB) in 2021, estimated population size for 2021 and Human Development Index for 2010, were collected from the Primary Care Health Information System (SISAB), the Brazilian Institute of Geography and Statistics (IBGE) and the e-Manager System of the Ministry of Health. The results obtained show that during the years analyzed the indicator had growth in all federative units and in the Federal District, however, some states had growth of the indicator above the national average: Amazonas, Tocantins, Alagoas, Ceará, Paraíba, Pernambuco, Rio Grande do Norte, Sergipe, Mato Grosso do Sul Paraná and Santa Catarina. The indicator had a negative correlation with HDI and a positive correlation with the coverage of family health and oral health teams. There was an increase in the proportion of dental care to pregnant women in PHC between the years studied, however, this indicator does not allow the evaluation of the quality of this care nor the impact on maternal and infant morbidity and mortality.

RESUMO

BACKGROUND: Exposure to domestic violence by triggering repetitive distress and fear can affect neurodevelopmental and mental health in the short and long term. This, in turn, has been linked to an increased risk of substance abuse, such as alcohol abuse in adulthood. OBJECTIVE: The present study aimed to evaluate the association between exposure to violence from the father toward the mother and alcohol abuse in Peruvian women. DESIGN: Cross-sectional study. METHODS: We conducted a secondary analysis of data from the Peruvian Demographic and Family Health Survey (ENDES) of 2019. A total of 19,980 reproductive-aged women (15-49 years old) were surveyed using the Health Questionnaire during 2019. The dependent variable of the study was alcohol abuse, collected through self-report, according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria. Intimate partner violence (IPV; violence perpetrated by the father against the mother) was considered as the exposure variable. To assess the association of interest, we only considered observations with complete data and used binary logistic regression models, calculating crude odds ratios and adjusted odds ratios (aOR). For the multivariable model, we adjusted for confounding variables (age, marital status, education level, wealth index, ethnicity, residence, current smoker, depression, and IPV). RESULTS: We analyzed a final sample of 9953 women. The prevalence of interparental violence and alcohol abuse was 41.3% and 1.5%, respectively. We found that interparental violence was associated with higher odds of alcohol abuse (aOR: 2.10; 95% CI: 1.03-4.28) after adjusting for age, marital status, education level, wealth level, ethnicity, area of residence, current smoking, depression, and IPV. CONCLUSION: We identified that women of reproductive age who have been exposed to interparental violence were at higher odds of experiencing alcohol abuse issues.

Understanding the link between witnessing parental violence and alcohol abuse in Peruvian womenWitnessing violence between parents during childhood can leave deep emotional scars. This study explores whether such experiences are related to alcohol abuse among Peruvian women in their adult years. Using data from a national health survey in Peru, the experiences of nearly 20,000 women were analyzed to determine if witnessing violence between their parents during childhood was linked to alcohol problems later in life. Responses from the 2019 Peruvian Demographic and Family Health Survey were examined, focusing on women's reports of childhood exposure to violence between parents and current alcohol abuse, controlling for factors like age, education, and mental health. The study found that women who witnessed their parents engaging in violence were more likely to abuse alcohol as adults. About 41% of the women reported seeing such violence, and of these, a higher proportion struggled with alcohol compared to those who did not witness violence. Understanding the link between childhood experiences and adult behaviors can help develop targeted interventions to prevent alcohol abuse. This research highlights the need for support systems that help women cope with the emotional impacts of childhood trauma, potentially reducing alcohol-related problems in the future.

RESUMO

This cross-sectional study assessed the magnitude of inequalities in self-rated oral health (SROH) among different socioeconomic groups in Brazil. Secondary data from interviews with a sample of adults (≥18 years) from the national health survey 2013 (n = 64,308) and 2019 (n = 88,531) were analyzed. Positive SROH was considered when participants selected the good or very good options. Socioeconomic indicators were monthly household income and years of education. The magnitude of inequalities among socioeconomic groups was estimated using the Slope (SII) and Relative Index of Inequality (RII). Interaction term assessed changes in SII/RII over time. Estimates were adjusted for sex and age. The prevalence of SROH was 67.50% in 2013 and 69.68% in 2019. Individuals with lower socioeconomic indicators had a lower prevalence of positive SROH. Significant reductions in the magnitude of the education-based RII between 2013 (1.58) and 2019 (1.48) in Brazil, as well as in north (1.70; 1.45) and northeast (1.50; 1.41) regions and reduction in the income-based RII in the north (1.71; 1.51) were observed. Socioeconomic inequalities in SROH persist across different Brazilian regions, although there was a reduction in disparities among education groups in 2019 compared with 2013. The findings of this study suggest that equitable Brazilian oral health policies may have contributed to reducing SROH inequality over time.

RESUMO

To analyze the distribution and factors associated with lack of knowledge about the human papillomavirus (HPV) vaccine among Brazilian adolescents.Cross-sectional study using the 2019 National School Health Survey among 17,805 Brazilian students of public and private schools, aged 13-17 years. The outcome variable was "lack of knowledge about the HPV vaccine" and the explanatory variables were sociodemographic, behaviors, knowledge, and health conditions. Logistic regression model was used to calculate Odds Ratio (OR) and 95% confidence intervals (95%CI). Spatial analysis techniques were used to determine the formation of clusters in the federated units with similar proportions of adolescents who were unaware of the vaccine. The lack of knowledge about the HPV vaccine was reported by 45.54% of Brazilian students. There was a higher chance of lack of knowledge having had sexual intercourse (OR 1.43; 95% CI 1.20-1.70); attending public school (OR 1.72; 95%CI 1.47-2.02) and located in the Northeast Region (OR 1.35; 95%CI 1.08-1.69). The lower chance of lack of knowledge were female gender (OR 0.41; 95% CI 0.35-0.48), higher maternal education (OR 0.62; 95% CI 0.50-0.77) self-rated health as Poor/very poor (OR 0.64; 95% CI 0.49-0.86) and receiving contraceptive counseling (OR 0.77; 95% CI 0.65-0.91). The proportion of lack of knowledge about the HPV vaccine was higher with the formation of High-High spatial clusters in the states of Maranhão, Piauí, and Pernambuco. Sociodemographic, health, and behavioral conditions and knowledge of students, as well as school characteristics, were associated with lack of knowledge about the HPV vaccine. A higher frequency of lack of knowledge about the HPV vaccine among adolescents was found in the states of the Northeastern Region.

RESUMO

BACKGROUND: Population surveys are crucial for public policy planning and provide valuable representative data. In the health sector studies to identify and assess the prevalence of Arterial Hypertension (AH), a chronic non-communicable disease (NCD), along with its associated risk factors have been conducted. OBJECTIVES: This study aims to assess the effectiveness of a population health survey in estimating the prevalence of arterial hypertension (AH) in the Sorocaba municipality between August 2021 and June 2023. METHODS: The analyzed performance indicator is the precision (design effect - deff) of AH prevalence in adults (≥ 18 years) and their exposure to primary risk factors. The total sample included 1,080 individuals from the urban area, deemed sufficient to estimate a deff of 1.5. This cluster-based study utilized census sectors as clusters, with data collected through household interviews, standardized questionnaires, and measurements of blood pressure and biometric parameters. The deff calculation formula used was weighted variance / raw variance. The Research Ethics Committee approved this study, with registration CAAE 30538520-1-0000-5373. RESULTS: The deff values ranged from 0.44 for chronic obstructive pulmonary disease to 1.63 for asthma, with a deff of 1.00 for AH prevalence. CONCLUSION: The study demonstrated good precision in its results, with high receptivity and cooperation from participants. The cost-effectiveness of the research deemed appropriate. The technique of selecting households within clusters (census sectors) based on detailed mapping and demographic data from the Instituto Brasileiro de Geografia e Estatística (IBGE) proved to be practical and efficient, suitable for replication in other municipalities and for studying other NCDs.

RESUMO

BACKGROUND: Self-perception of oral health is a recognized indicator, based on a single question. Association among oral health and socioeconomic status has been well established, however in Brazil, no results were found on the relation with type of insertion in labor market. OBJECTIVE: The aim of this study was to describe the prevalence of negative self-perception of oral health and associated factors, according to gender among Brazilian workers population, in 2019. METHODS: The National Health Survey, nationwide household-based survey, carried out in 2019, was used as source of data. Absolute and relative frequencies were calculated to understand the distribution of variables of interest and characterize the sample (n = 54,343). Binary logistic regression was used in the analyses. Odds ratio (OR) was estimated using a 95% confidence interval in bivariate and multivariate analyses. RESULTS: The prevalence of negative self-perception of oral health was 29.3%; in that, 31.0% among men and 27.2% among women. Compared to formal employees, the chance of negative self-perception of oral health among the informal workers was almost 20% higher among men and 13% among women after adjusting for all confounding factors. Unemployed women were 33% more likely to have negative self-perception of oral health. CONCLUSIONS: Self-reported unemployment increased the chance of a negative self-perception of oral health among women; however, the same effect was not observed among men. Why is there a difference? The association between informal work and negative SEOH is relevant in the Brazilian context of work deregulation and growth in the number of people without access to formal employment. The results suggested addressing employment conditions in adult oral health promotion actions, with emphasis on gender differences.

RESUMO

BACKGROUND: The acceptability and preference for clear aligner therapy (CAT) has been increasing among orthodontists, but there is still a lack of consensus regarding CAT best practices. Consequently, this study aimed to investigate CAT practices among orthodontists practicing in Canada. METHODS: The survey was conducted among orthodontists practicing in Canada using a modified previously published survey. Sixty orthodontists participated (6.1% response rate). It consisted of 11 sections with open and closed questions related to demographic information and particularities about using or not using CAT. The survey responses were exported from REDCap to a Microsoft Excel (Microsoft, Redmond, Wash) spreadsheet, then statistically analyzed using SPSS software (SPSS for Windows, version 21.0; IBM Inc., Armonk, NY, USA). The comments were categorized under themes and subthemes. Data were organized in descriptive statistics, expressing frequencies and percentages. RESULTS: Almost 30% of the orthodontist's annual caseload was treated with CAT, most frequently prescribed to adult patients. Case complexity and patient cooperation were the factors that most influenced the decision to prescribe CAT. Almost half of orthodontists reported sometimes combining CAT with adjunctive fixed appliances. CONCLUSIONS: Most orthodontists prescribe CAT, and its use is based on the malocclusion's complexity. Orthodontists who do not prescribe CAT believe that fixed appliance therapy has superior treatment outcomes.

RESUMO

OBJECTIVES: To determine the association between smoking and tooth loss in individuals aged 18 years or more living in Brazil. METHODS: Secondary analysis of the 2019 Brazilian National Health Survey data. The outcome was self-reported tooth loss, and the main independent variable was tobacco smoking. Family income, schooling, sex and age were covariates. Multiple linear regression analysis determined the association between tobacco smoking and the number of missing teeth and then the average number of missing teeth was predicted according to smoking status. RESULTS: The mean number of missing teeth in 88,531 individuals aged 18 or more was 7.7 (95%CI: 7.6-7.8). At least one missing tooth was identified in 72.0% (95%CI: 71.4-72.6) of the population, 21.3% (95%CI: 20.9-21.7) had a non-functional dentition, 14.2% (95%CI: 13.9-14.6) had severe tooth loss and 10.3% (95%CI: 10.0-10.6) were edentulous. The adjusted regression coefficients for number of missing teeth showed that current or former smokers, individuals with low family income and schooling, older age and females exhibited higher tooth loss. Current and former smokers had 1.40 (95%CI: 1.35-1.46) and 1.13 (95%CI: 0.54-0.98) times more lost teeth than never smokers, respectively. CONCLUSIONS: Both tooth loss and smoking are common in Brazilians and are associated. Unfavorable socioeconomic status and demographic factors also predict tooth loss.

RESUMO

RESUMO O estudo descreveu as características dos indivíduos que utilizam os serviços da Atenção Primária à Saúde (APS) e avaliou a associação entre a avaliação elevada dos atributos da APS, sob a ótica dos usuários, com o estado de saúde e o uso dos serviços de saúde no Brasil. Trata-se de um estudo transversal que analisou dados da Pesquisa Nacional de Saúde 2019, com amostra de 9.562 adultos que responderam ao Primary Care Assessment Tool (PCATool). Foi testada a associação entre avaliação elevada da APS (escore geral ≥ 6,6) e estado de saúde e uso dos serviços. Verificou-se que os usuários adultos que mais utilizam a APS pública têm entre 40 e 59 anos, são mulheres, de baixa escolaridade e pardos. Os que melhor avaliaram a APS foram indivíduos que utilizaram o mesmo serviço, procuraram serviços nas últimas duas semanas e se internaram. Maior uso dos serviços aponta para melhor avaliação da APS.

ABSTRACT The present study described the characteristics of individuals who use Primary Health Care (PHC) services and evaluated the association between the high assessment of PHC attributes, from the perspective of users, with health conditions and the use of health services in Brazil. This work is a cross-sectional study that analyzed data from the 2019 National Health Survey, in which 9,562 adults responded to the Primary Care Assessment Tool (PCATool). The association between high PHC assessment (general score ≥ 6.6) and health conditions and the use of services was tested, and it was found that the adult users who most use public PHC are between 40 and 59 years of age, women, with a low level of education, and brown. Those who best evaluated PHC were individuals who used the same service, who sought out services in the last 2 weeks, and who had been hospitalized. The greater use of health services points to a better assessment of PHC.

RESUMO

OBJECTIVE: Estimate COVID-19 vaccine booster uptake and identify sociodemographic profiles associated with vaccine booster uptake in Mexican adults aged 60 and older. METHODS: Using data from the 2022 National Health and Nutrition Survey, we estimated COVID-19 booster uptake in Mexican adults 60 and older. We conducted a latent class analysis using sociodemographic characteristics and then estimated group-specific booster prevalence. RESULTS: Adults aged 60 and older with a completed vaccination schedule had 80.3% booster coverage. Two groups showed the lowest coverage: 1) unemployed and informal working men with elementary education with low socioeconomic status (73.8% boosted), and 2) female homekeepers with elementary education or less living in rural areas (77.0% boosted). CONCLUSIONS: Our analysis points to the need to reach out to men and women with elementary education or less who live in rural areas to strengthen booster campaigns in the future.

RESUMO

To estimate the prevalence of simultaneous insufficient physical activity (IPA) and excessive con-sumption of ultra-processed foods (UPF), and to verify the association between IPA and dietary habits (in natura/minimally processed foods, ultra-processed foods and food consumption markers) in Brazilian adults. Cross-sectional study with data from the Vigitel Telephone Survey 2018. 51,064 adults (≥ 20 years) were studied. IPA covered three domains: leisure, commuting and work (< 150 minutes/week). The scores for in natura/minimally processed foods and UPF (number of subgroups mentioned/previous day) were calculated; ≥ 5 UPF: excessive consumption. Questions on weekly and daily frequency of food consumption were used. Prevalence ratios (PR) were estimated by Poisson regression. The simultaneity of IPA and consumption of UPF was 7.0% (95% CI: 6.50 - 7.55), higher among women (PR = 1.26; 95% CI: 1.08 - 1.47), in residents of the Southeast (PR = 1.23; 95% CI: 1.00 - 1.51) and South (PR = 1.50; 95% CI: 1.22 - 1.84), and was lower in individuals aged ≥ 40 years (40-49: PR = 0.71; 95% CI: 0.56 - 0.88; 50-59: PR = 0.46; 95% CI: 0.36 - 0.58; ≥ 60: PR = 0.45; 95% CI: 0.36 - 0.56) and with health insurance (PR = 0.84; 95% CI: 0.72 - 0.99). IPA was associated with lower consumption of in natura/minimally processed foods and higher consumption of UPF. There was lower regular consumption (≥ 5 days/week) of raw vegetables (PR = 0.82; 95% CI: 0.78 - 0.85), cooked vegetables (PR = 0.88; 95% CI: 0.84 - 0.92), fruit (PR = 0.78; 95% CI: 0.75 - 0.82) and juice (PR = 0.93; 95% CI: 0.89 - 0.97), and higher consumption of soft drinks (≥ 3 days/week: PR = 1.17; 95% CI: 1.11 - 1.23) among individuals with IPA. They also had lower consumption of raw vegetables (2 times/day: PR = 0.93; 95% CI: 0.88 - 0.98), fruit (2 times/day: PR = 0.89; 95% CI: 0.85 - 0.94; ≥ 3 times: PR = 0.84; 95% CI: 0.79 - 0.89) and juice (≥ 2 glasses/day: PR = 0.93; 95% CI: 0.89 - 0.98). An association was identified between IPA and inadequate eating habits, the subgroups most affected by both risk behaviors, which should be prioritized in health promotion and disease prevention strategies.

Estimar a prevalência de simultaneidade de atividade física insuficiente (AFI) e consumo excessivo de alimentos ultraprocessados (AUP), bem como verificar a associação entre AFI e hábitos alimentares (alimentos in natura/minimamente processados, ultraprocessados e marcadores de consumo alimentar) em adultos brasileiros. Estudo transversal com dados do inquérito telefônico Vigitel 2018. Foram estudados 51.064 adultos (≥ 20 anos). AFI abarcou três domínios: lazer, deslocamento, trabalho (< 150 minutos/semana). Calcularam-se os escores de alimentos in natura/minimamente processados e AUP (número de subgrupos referidos/dia anterior); ≥ 5 AUP: consumo excessivo. Foram utilizadas questões sobre a frequência semanal e diária de consumo alimentar. Estimaram-se razões de prevalência (RP) com regressão de Poisson. A simultaneidade de AFI e consumo de AUP foi de 7,0% (IC 95%: 6,50 - 7,55), maior nas mulheres (RP = 1,26; IC 95%: 1,08 - 1,47), nos residentes do Sudeste (RP = 1,23; IC 95%: 1,00 - 1,51) e Sul (RP = 1,50; IC 95%: 1,22 - 1,84), e foi menor nos indivíduos com idade ≥ 40 anos (40-49: RP = 0,71; IC 95%: 0,56 - 0,88; 50 - 59: RP = 0,46; IC 95%: 0,36 - 0,58; ≥ 60: RP = 0,45; IC 95%: 0,36 - 0,56) e com plano de saúde (RP = 0,84; IC 95%: 0,72 - 0,99). A AFI associou-se ao menor consumo de alimentos in natura/minimamente processados e ao maior consumo de AUP. Observou-se menor consumo regular (≥ 5 dias/semana) de hortaliças cruas (RP = 0,82; IC 95%: 0,78 - 0,85), cozidas (RP = 0,88; IC 95%: 0,84 - 0,92), frutas (RP = 0,78; IC 95%: 0,75 - 0,82), suco (RP = 0,93; IC 95%: 0,89 - 0,97), e maior de refrigerante (≥ 3 dias/semana: RP = 1,17; IC 95%: 1,11 - 1,23) entre os indivíduos com AFI. Estes também apresentaram menor consumo de hortaliças cruas (2 vezes/dia: RP = 0,93; IC 95%: 0,88 - 0,98), frutas (2 vezes/dia: RP = 0,89; IC 95%: 0,85 - 0,94; ≥ 3 vezes/dia: RP = 0,84; IC 95%: 0,79 - 0,89) e suco (≥ 2 copos/dia: RP = 0,93; IC 95%: 0,89 - 0,98). Identificou-se associação entre AFI e hábitos alimentares inadequados, os subgrupos mais acometidos por ambos os comportamentos de risco, que devem ser priorizados em estratégias de promoção da saúde e prevenção de agravos.

RESUMO

Objective: To estimate the prevalence of trachoma in indigenous and non-indigenous populations in selected areas of the state of Maranhão, in northeastern Brazil. Methods: This was a population-based survey with probabilistic sampling. For the diagnosis of trachoma, external ocular examination was performed using head magnifying loupes, at 2.5X magnification. The prevalence of trachomatous inflammation - follicular (TF) in children aged 1-9 years and the prevalence of trachomatous trichiasis (TT) in the population aged ≥15 years were estimated. Relative frequencies of sociodemographic and environmental characteristics were obtained. Results: The study included 7 971 individuals, 3 429 from non-indigenous populations and 4 542 from indigenous populations. The prevalence of TF in non-indigenous and indigenous populations was 0.1% and 2.9%, respectively, and the prevalence of TT among indigenous populations was 0.1%. Conclusions: The prevalence of TF and TT in the two evaluation units in the state of Maranhão were within the limits recommended for the elimination of trachoma as a public health problem. However, the prevalence of TF was higher in the indigenous evaluation unit, indicating a greater vulnerability of this population to the disease. The prevalence of TF of below 5.0% implies a reduction in transmission, which may have resulted from improved socioeconomic conditions and/or the implementation of the World Health Organization SAFE strategy.

RESUMO

OBJECTIVES: To estimate the prevalence and factors associated with Driving Under the Influence of Alcohol (DUIA) among car drivers and motorcyclists in Brazil and to evaluate the association between DUIA and self-reported Road Traffic Injuries (RTIs) in these groups. METHODS: A cross-sectional study was conducted using data from adults aged 18 or older who participated in the 2019 National Health Survey. Probability sampling was used to recruit participants, and data collection was carried out through home visits. Data from 31,246 car drivers and 21,896 motorcyclists were analyzed. Key indicators included the proportion (%) of car drivers who consumed alcohol and then drove in the past 12 months and the proportion (%) of motorcyclists who consumed alcohol and then drove in the past 12 months. Multiple Poisson regression was used to determine factors associated with DUIA and the association of this variable with RTIs in both groups. RESULTS: DUIA prevalence was 9.4% (95% Confidence Interval [95% CI] = 8.8-10.0) among car drivers and 11.2% (95% CI = 10.4-12.1) among motorcyclists. Among car drivers, DUIA prevalence was higher in men, young adults, those without a spouse/partner, and lower in individuals with lower income and education level. Among motorcyclists, DUIA prevalence was higher in men, young adults, those living outside the capitals and metropolitan regions, and lower in individuals with lower income. DUIA increased the prevalence of self-reported RTIs in the previous 12 months among car drivers and motorcyclists. CONCLUSIONS: A high prevalence of DUIA was evident among drivers, particularly motorcyclists. The DUIA was more prevalent among men and young adults. The DUIA was associated with an increased magnitude of self-reported RTIs among car drivers and motorcyclists. Despite the extensive legislation for zero tolerance toward DUIA in the country, actions need stricter enforcement.

RESUMO

Background: Identification of unvaccinated children is important for preventing deaths due to infections. Number of siblings and birth order have been postulated as risk factors for zero-dose prevalence. Methods: We analysed nationally representative cross-sectional surveys from 85 low and middle-income countries (2010-2020) with information on immunisation status of children aged 12-35 months. Zero-dose prevalence was defined as the failure to receive any doses of DPT (diphtheria-pertussis-tetanus) vaccine. We examined associations with birth order and the number of siblings, adjusting for child's sex, maternal age and education, household wealth quintiles and place of residence. Poisson regression was used to calculate zero-dose prevalence ratios. Findings: We studied 375,548 children, of whom 13.7% (n = 51,450) were classified as zero-dose. Prevalence increased monotonically with birth order and with the number of siblings, with prevalence increasing from 11.0% for firstborn children to 17.1% for birth order 5 or higher, and from 10.5% for children with no siblings to 17.2% for those with four or more siblings. Adjustment for confounders attenuated but did not eliminate these associations. The number of siblings remained as a strong risk factor when adjusted for confounders and birth order, but the reverse was not observed. Among children with the same number of siblings, there was no clear pattern in zero-dose prevalence by birth order; for instance, among children with two siblings, the prevalence was 13.0%, 14.7%, and 13.3% for firstborn, second, and third-born, respectively. Similar results were observed for girls and boys. 9513 families had two children aged 12-35 months. When the younger sibling was unvaccinated, 61.9% of the older siblings were also unvaccinated. On the other hand, when the younger sibling was vaccinated, only 5.9% of the older siblings were unvaccinated. Interpretation: The number of siblings is a better predictor than birth order in identifying children to be targeted by immunization campaigns. Zero-dose children tend to be clustered within families. Funding: Gavi, the Vaccine Alliance.

RESUMO

OBJECTIVE: To evaluate the relationship between oral health status, self-perception of oral health, and depression. METHODS: This cross-sectional study included 2953 individuals that were ≥ 18 years of age and participated in the Chilean National Health Survey (NHS), 2016-2017. Information on oral, dental, and mental health, and the presence or absence of depressive symptoms was collected. Secondary data analysis was carried out using STATA and included logistic regression models adjusted for sex, age, and educational level. The analyses factored in the expansion weights to estimate representative prevalences of the entire population. RESULTS: Participants experiencing frequent dental or prosthesis-related discomfort while speaking (OR: 1.57; 95% CI: 1.01-2.43) were related with exhibiting suspected depression. Removable upper denture users were at a higher risk of exhibiting suspected (OR: 2.04; 95% CI: 1.11-3.74) than those not using them. Participants diagnosed with depression in the past 12 months had a similar number of teeth (median = 24) compared to those without depression (median = 25) (OR: 0.99; 95% CI: 0.96-1.02). CONCLUSION: Experiencing dental or prosthesis-related difficulties in speaking is related to suspected depression or a diagnosis of depression. These findings highlight the importance of developing comprehensive healthcare approaches that consider mental health in the context of oral health.

RESUMO

INTRODUCTION: Oral diseases affect a significant proportion of the world's population, yet international comparisons involving oral health outcomes have often been limited due to differences in the way country-level primary data are collected. In response to this, the World Dental Federation (FDI) Oral Health Observatory project was launched with the goal of collecting and producing standardised international data on oral health across countries. The aim of this descriptive cross-sectional study was to examine associations between self-reported general health and a range of factors (sociodemographics, oral health-related behaviours, oral impacts, clinical variables) using these standardised international datasets. METHODS: Dentists within FDI member National Dental Associations who chose to take part in the project were selected using a multistage sampling method. The number of dentists in each cluster was set according to the proportion of the national population living in the area, and 50 patients per dentist were systematically approached to take part. Patients and dentists completed 2 separate questionnaires on a mobile app. Ordinal logistic regression (conducted in December 2022) was used to analyse the linked patient and dentist data from 6 countries: China (n = 2242); Colombia (n = 1029); India (n = 999); Italy (n = 711); Japan (n = 1271); and Lebanon (n = 798). Self-reported general health was the dependent variable, with age, sex, education, self-reported oral health-related behaviours, self-reported oral impacts, and clinical variables acting as the independent variables. RESULTS: The results demonstrated a different pattern of associations in the different countries. Better self-reported general health was associated with degree-level education in all 6 countries and with reporting no oral impact and no sensitive teeth in 4 countries. Several country-specific patterns were also found, including the importance of tooth brushing in Colombia, periodontal health in Italy, and differing associations with sugary drinks consumption in India and Japan. CONCLUSIONS: These descriptive findings provide a basis for further research and, importantly, for advocacy in identifying patient oral health care needs according to both person-reported and clinical aspects. This can facilitate optimisation of service provision and potentially influence policy and investments.

RESUMO

Resumo: O objetivo desta pesquisa foi investigar a relação da prática de atividade física nos quatro domínios (tempo livre, deslocamento, doméstico e trabalho) e a prevalência de sintomas depressivos em adultos brasileiros, de maneira geral e estratificando-se por sexo, escolaridade e ter ou não diagnóstico referido de depressão. Estudo transversal, com dados de 88.531 indivíduos de 18 anos ou mais, respondentes da Pesquisa Nacional de Saúde de 2019. Os sintomas depressivos foram avaliados pelo Patient Health Questionnaire-9 (Questionário de Saúde do Paciente-9, PHQ-9). Foram considerados fisicamente ativos aqueles que referiram realizar atividade física pelo menos uma vez por semana no respectivo domínio. Adicionalmente, foi realizado o cálculo de tempo de prática semanal, sendo posteriormente divididos em quartis em cada domínio. Para as análises de associação, foram calculados o odds ratio bruto (ORbruto) e ajustado (ORajustado), no total e nas análises estratificadas. Os fisicamente ativos no tempo livre tiveram menor chance de apresentar sintomas depressivos, no total (ORajustado = 0,74; IC95%: 0,64-0,86) e em todas as estratificações, menos naqueles com depressão autorreferida. As associações na atividade física no tempo livre foram mais frequentes naqueles que praticavam entre 121 e 360 minutos semanais. Os indivíduos ativos nos domínios de deslocamento, doméstico e trabalho tiveram maior chance de apresentar sintomas depressivos em alguns grupos, com resultados mais consistentes para a atividade física doméstica. Os resultados evidenciaram que a relação da atividade física com a depressão em brasileiros varia conforme o domínio e a duração da atividade física, e que a ideia de que "todo movimento conta" parece adequada apenas para o domínio de tempo livre.

Resumen: Este estudio tuvo como objetivo investigar la práctica de actividad física en cuatro dominios (ocio, desplazamiento, actividad doméstica y trabajo) y la prevalencia de síntomas depresivos en adultos brasileños, en general y estratificada por sexo, escolaridad y diagnóstico de depresión autoinformado. Se trata de un estudio transversal con datos de 88.531 individuos de 18 años o más, que respondieron la Encuesta Nacional de Salud en el 2019. Los síntomas depresivos se evaluaron mediante el Cuestionario sobre la Salud del Paciente-9 (PHQ-9). Aquellos que realizan actividad física al menos una vez por semana en un dominio determinado se consideraron físicamente activos. Además, se calculó el tiempo de actividad física y luego se dividió en cuartiles para cada dominio. Para los análisis de asociación, se calcularon el odds ratio crudo (ORcrudo) y el odds ratio ajustado (ORajustado) para los análisis total y estratificado. Los individuos que son físicamente activos en durante el ocio presentaron menos probabilidades de tener síntomas depresivos, en el total (ORajustado = 0,74; IC95%: 0,64-0,86) y en todas las estratificaciones, excepto los individuos con depresión autoinformada. Las asociaciones de actividad física en el tiempo libre fueron más frecuentes en quienes practicaban de 121 a 360 minutos/semana. Los individuos que eran activos en los dominios desplazamiento, actividad doméstica y trabajo tuvieron más probabilidades de presentar síntomas depresivos en algunos grupos, con resultados más consistentes para las actividades domésticas. Los resultados mostraron que la relación entre actividad física y depresión entre los brasileños varía según el dominio y la duración, y el concepto de que "cada movimiento cuenta" parece ser correcto solo para el dominio del ocio.

Abstract: This study aimed to investigate the practice of physical activities in the four domains (leisure time, transportation, household, and work) and the prevalence of depressive symptoms in Brazilian adults, in general and stratified by sex, schooling level, and having or not a self-reported diagnosis of depression. This is a cross-sectional study with data from 88,531 individuals aged 18 years or older, who responded to the Brazilian National Health Survey in 2019. The depressive symptoms were evaluated by the Patient Health Questionnaire-9 (PHQ-9). Those who practice physical activities at least once a week in a given domain were considered physically active. Additionally, the calculation of physical activities duration was conducted and later divided into quartiles for each domain. For the association analyses, the crude odds ratio (crudeOR) and adjusted odds ratio (adjustedOR) were calculated for the total and stratified analyses. Individuals who are physically active during leisure time showed a lower chance of presenting depressive symptoms, in total (adjustedOR = 0.74; 95%CI: 0.64-0.86) and in all stratifications, except for individuals with self-reported depression. The associations of leisure-time physical activity were most frequent in those who practice from 121 to 360 minutes/week. The individuals who were active in the transportation, household, and work domains had a higher chance of presenting depressive symptoms in some groups, with more consistent results for household physical activities. The results showed that the relationship between physical activities and depression among Brazilians varies according to domain and duration, and that the concept that "every move counts" seemed to be correct only for the leisure-time domain.

RESUMO

SUMMARY OBJECTIVE: The aim of this study was to estimate the prevalence of influenza immunization in elderly people in Brazil in 2019. METHODS: This is a population-based cross-sectional study. The Brazilian individuals (≥60 years) who participated in the 2019 National Health Survey were included. The survey was conducted in permanent households in Brazil from August 2019 to March 2020. The prevalences of influenza vaccination and their respective confidence intervals (95%CI) were estimated according to sociodemographic characteristics and the diagnosis of chronic diseases. RESULTS: The prevalence of influenza vaccination was 72.4% (95%CI 71.5-73.2), with statistically significant differences observed between genders (p=0.001), age groups (p=0.001), and those living with a spouse/partner (p=0.002). Significant differences were found in groups with arterial hypertension (75.2%, p<0.001), diabetes (77.2%, p<0.001), and arthritis or rheumatism (75.5%, p<0.001). CONCLUSION: A global prevalence of influenza vaccination of 72.4% was estimated among elderly people in Brazil.

RESUMO

Resumo Este estudo transversal objetivou estimar a prevalência e os fatores associados à violência contra as mulheres rurais e descrever os casos positivos segundo autoria, local e frequência, com dados da Pesquisa Nacional de Saúde (2019). Calcularam-se as prevalências brutas e ajustadas de violência contra as mulheres rurais de todo o Brasil nos últimos 12 meses, segundo perfil demográfico, apoio e saúde por meio da regressão de Poisson. A violência psicológica foi de 18%, a física, de 4,4% e a sexual, de 1,5%. Os principais autores eram pessoas conhecidas, a maior parte dos casos ocorreu na residência e as agressões eram recorrentes. As maiores prevalências: mulheres adultas jovens (24,2%), solteiras e divorciadas (20% cada), com ensino fundamental completo ao superior incompleto (22%),, percepções de saúde muito ruim (34%), ruim (30%) e aquelas com problema de saúde mental (30%). Após o ajuste, permaneceram no modelo as de 30-39 anos e de 40 a 49 anos, casadas, com estado de saúde muito ruim, ruim e regular e com problema de saúde mental. Aponta-se para a alta prevalência de violência contra as mulheres rurais.

Abstract The aim of this cross-sectional study was to estimate the prevalence of violence against women living in rural areas, explore associated factors, and characterize cases of violence according to perpetrator, place of occurrence, and frequency. Based on data from the 2019 National Health Survey, using Poisson's regression we calculated crude and adjusted prevalence ratios for violence committed during the last 12 months against women living in rural areas across Brazil, focusing on the following variables: sociodemographic characteristics, income, social support, and self-reported health status. The prevalence of psychological, physical, and sexual violence was 18%, 4.4%, and 1.5%, respectively. Perpetrators were mainly people known to the victim and violence was mainly committed at home and repeated over time. Prevalence was highest among young women (24.2%), single and divorced women (20% each), women who had complete elementary school till not complete higher education (22% each), women with very poor (34%) and poor (30%) self-perceived health status; and women with a mental health problem (30%). After adjustment, the following variables were retained in the model: women aged 30-39 years and 40-49 years; married women; women with very poor, poor, and fair perceived health; and women diagnosed with a mental health problem.
