RESUMEN

This study aimed to identify the dietary patterns of Brazilian children aged 6-23 months and to investigate their association with maternal socio-demographic factors. Data from the 2019 Brazilian National Health Survey were used in this cross-sectional study. Mothers of 1616 children aged 6-23 months reported on their children's dietary intake. Dietary patterns were identified using principal component analysis, and their associations with maternal socio-demographic characteristics were assessed using linear regression models. The first consisted of healthy patterns and the second, unhealthy ones. Linear regression showed that adherence to a healthy dietary pattern was higher among children of mothers who were older (ß = 0.02, p = 0.01), had more years of education (ß = 0.49, p = 0.04), reported living with a partner (ß = 0.29, p = 0.01), and resided in an urban area (ß = 0.35, p = 0.01). Conversely, adherence to the unhealthy pattern was positively associated with mothers who declared themselves as black or brown (ß = 0.25, p = 0.03). Our results show that older mothers with higher levels of education and paid work and who live with a partner are more likely to contribute to their children's healthy eating patterns. We conclude that socio-demographic factors may influence the quality of the food offered to children. Nevertheless, advocating for public policies promoting nutritious complementary diets emphasising fresh and minimally processed foods remains crucial for children whose mothers do not possess these favourable socio-demographic characteristics.

RESUMEN

OBJECTIVE: Food insecurity (FI) is the lack of daily access for everyone to quality food in sufficient quantity. In many populations, it presents as a chronic and persistent condition. This study analysed the association between the length of time living with FI and socio-demographic conditions in households in a semi-arid municipality in the Brazilian Northeast between 2011 and 2019. DESIGN: This is a population-based cohort study among families in the municipality in Northeast Brazil (2011, 2014 and 2019). FI was estimated through the Escala Brasileira de Insegurança Alimentar (EBIA, Brazilian Household Food Insecurity Measurement Scale), and the longitudinal category of time of living with FI was adopted to classify them according to the time they remained in FI during the cohort. The association with the socio-demographic profiles of the population was verified through multinomial logistic regression. SETTING: Households in semi-arid, Northeast of Brazil. PARTICIPANTS: Household respondents interviewed in 2011, 2014 and 2019 (n 274). RESULTS: Sixty-seven percentage (67 %) of families lived in FI in this period. Rural residence, low monthly per capita income and low schooling of the household reference person increased the chances of these families living longer in FI. These overlapping conditions increased the odds of FI in the household. CONCLUSIONS: Coping with FI requires intersectoral intervention that improves the socio-demographic conditions of the population.

RESUMEN

Introducción: La enfermedad por coronavirus (COVID-19) se ha extendido entre la población de todo el país y ha tenido un gran impacto a nivel mundial. Sin embargo, existen diferencias geográficas importantes en la mortalidad de COVID-19 entre las diferentes regiones del mundo y en Costa Rica. Objetivo: Explorar el efecto de algunos de los factores sociodemográficos en la mortalidad de COVID-19 en pequeñas divisiones geográficas o cantones de Costa Rica. Métodos: Usamos registros oficiales y aplicamos un modelo de regresión clásica de Poisson y un modelo de regresión ponderada geográficamente. Resultados: Obtuvimos un criterio de información de Akaike (AIC) más bajo con la regresión ponderada (927.1 en la regresión de Poison versus 358.4 en la regresión ponderada). Los cantones con un mayor riesgo de mortalidad por COVID-19 tuvo una población más densa; bienestar material más alto; menor proporción de cobertura de salud y están ubicadas en el área del Pacífico de Costa Rica. Conclusiones: Una estrategia de intervención de COVID-19 específica debería concentrarse en áreas de la costa pacífica con poblaciones más densas, mayor bienestar material y menor población por unidad de salud.

Introduction: The coronavirus disease (COVID-19) has spread among the population of Costa Rica and has had a great global impact. However, there are important geographic differences in mortality from COVID-19 among world regions and within Costa Rica. Objective: To explore the effect of some sociodemographic factors on COVID-19 mortality in the small geographic divisions or cantons of Costa Rica. Methods: We used official records and applied a classical epidemiological Poisson regression model and a geographically weighted regression model. Results: We obtained a lower Akaike Information Criterion with the weighted regression (927.1 in Poisson regression versus 358.4 in weighted regression). The cantons with higher risk of mortality from COVID-19 had a denser population; higher material well-being; less population by health service units and are located near the Pacific coast. Conclusions: A specific COVID-19 intervention strategy should concentrate on Pacific coast areas with denser population, higher material well-being and less population by health service units.

RESUMEN

The amount of walking for daily transport has decreased significantly over the last decades in Temuco, Chile. Moreover, the percentage of older adults (aged over 65) who did not meet the recommendations of at least 150 min of physical activity per week has increased during this time. In this regard, the present study examines the contribution of socio-demographic and built environment factors on the walking behavior of older adults in Temuco, Chile, with a view to improving their level of physical activity. A cross-sectional study was conducted among 463 older adults aged 60 years and over. Travel Diary Data taken from "Encuesta Origin Destino" (EOD) 2013, Geographic information systems (GIS), audits (PEDS with certain revisions) and finally, multiple regression analysis, were used to examine the objectives. Associations were found between the walking behavior of older adults and several socio-demographic factors, as well as several built environment factors including destination (the number of parks and the land use mix), functionality (street connectivity, length of street sections and off-street parking lots) and aesthetics (views of nature, building height, and articulation in building design). These findings should be considered by urban/transport policymakers to improve the walking behavior of older adults in this city.

RESUMEN

Objective: To analyze sociodemographic factors' influence on COVID-19 case fatality rate (CFR) in Ecuador on a subnational level. Methods: Publicly available register-based observational study. A retrospective cohort of COVID-19 infections between epidemiological weeks 8-53 in the Ecuadorian public healthcare system was determined from available records. Statistical analyses were conducted to evaluate CFR trends according to factors such as sex, age, location, and healthcare provider. Results: Overall CFR was 9.4%; by canton, median CFR was 5.2%, with some cantons with much higher rates, like Santa Elena (39.1%). Overall CFR decreased during the period, from 16.6% (week 8) to 2.63% (week 53). Being in a rural area was an independent protective factor. Patients over 65 had a hazard ratio of 11.38 (95% CI [11.05, 11.72]). Sex, ethnicity, and treatment from public facilities were also associated with death risk. Conclusion: CFR is a proxy indicator of COVID-19 impact in Ecuador, and this location-based analysis provides new information on the disease's specific impact subnationally. Overall COVID-19 CFR during the entire period was high, suggesting the need to improve COVID-19 care in Ecuador.

RESUMEN

The increase in active travel contributes to maintaining the minimum rate of physical activity and therefore has a positive impact on inhabitants' public health. The level of walking for daily transport has decreased significantly during the last decades in Temuco, Chile. This study examined the contribution of socio-demographic factors, active family environment, and built environment factors to walking behavior and walking level based on three types of destination in Temuco. The results of Encuesta Origin Destino (EOD 2013), geographic information system (GIS), and, finally, hierarchical multiple regression analysis were used to examine the objectives. Correlations were found between total walking behavior, walking level based on three destination types, and several socio-demographic factors such as age, gender, and access to TV and Internet. Furthermore, correlations were found between walking behavior and active family environment, as well as several built environment factors. For instance, the higher mixed land use as well as number of parks and plazas contribute towards more overall walking as well as two types of walking. Identifying that most persons who walk come from low-income families and the negative impact of network connectivity on overall walking are the major differences between this context and developed countries.

RESUMEN

The aim of this study is to analyze the effects of lockdown using natural language processing techniques, particularly sentiment analysis methods applied at large scale. Further, our work searches to analyze the impact of COVID-19 on the university community, jointly on staff and students, and with a multi-country perspective. The main findings of this work show that the most often related words were "family", "anxiety", "house", and "life". Besides this finding, we also have shown that staff have a slightly less negative perception of the consequences of COVID-19 in their daily life. We have used artificial intelligence models such as swivel embedding and a multilayer perceptron as classification algorithms. The performance that was reached in terms of accuracy metrics was 88.8% and 88.5% for students and staff, respectively. The main conclusion of our study is that higher education institutions and policymakers around the world may benefit from these findings while formulating policy recommendations and strategies to support students during this and any future pandemics.

RESUMEN

OBJECTIVES: This study examined how socio-demographic, climate and population health characteristics shaped the geospatial variability in excess mortality patterns during the COVID-19 pandemic in Mexico. METHODS: We used Serfling regression models to estimate all-cause excess mortality rates for all 32 Mexican states. The association between socio-demographic, climate, health indicators and excess mortality rates were determined using multiple linear regression analyses. Functional data analysis characterized clusters of states with distinct excess mortality growth rate curves. RESULTS: The overall all-cause excess deaths rate during the COVID-19 pandemic in Mexico until April 10, 2021 was estimated at 39.66 per 10 000 population. The lowest excess death rates were observed in southeastern states including Chiapas (12.72) and Oaxaca (13.42), whereas Mexico City had the highest rate (106.17), followed by Tlaxcala (51.99). We found a positive association of excess mortality rates with aging index, marginalization index, and average household size (P < 0.001) in the final adjusted model (Model R2=77%). We identified four distinct clusters with qualitatively similar excess mortality curves. CONCLUSION: Central states exhibited the highest excess mortality rates, whereas the distribution of aging index, marginalization index, and average household size explained the variability in excess mortality rates across Mexico.

RESUMEN

BACKGROUND: Relevant evidence has addressed the negative impact of food processing on health. However, maternal ultra-processed food consumption is poorly investigated. AIM: To analyze food consumption according to the degree of food processing, dietary diversity, and associated socio-demographic factors during pregnancy. METHODS: Cross-sectional data was taken from a birth cohort in Rio de Janeiro, Brazil, with 142 pregnant women. We assessed diet using a qualitative food frequency questionnaire and classified food items according to the NOVA classification system as non-ultra-processed-foods and ultra-processed-foods. Non-ultra-processed-food and ultra-processed-food scores were calculated, reflecting weekly intake of more than one subgroup. Dietary diversity of the non-ultra-processed-food diet fraction was described according to the Food and Agriculture Organization guidelines. The association between food consumption and socio-demographic factors were investigated using logistic regression models. RESULTS: Over 60% of the pregnant women reported consumption of at least three non-ultra-processed-food groups. However, only 25% had adequate dietary diversity. The level of education (Complete high school: odds ratio, 5.36; 95% confidence interval, 1.73-16.65) was associated with regular intake of "meat and eggs." Among the ultra-processed-food score, 27% of the participants described a weekly consumption of at least two ultra-processed-food subgroups. White women (odds ratio, 2.63; 95% confidence interval, 1.05-6.63) had a higher chance of reporting "packaged ready meals" consumption. CONCLUSIONS: This study shows a high weekly consumption of ultra-processed-food subgroups and low dietary diversity of the non-ultra-processed-food fraction of the diet of pregnant women in Brazil. Our results elucidate the influence of socio-demographic characteristics on diet quality during pregnancy.

RESUMEN

Resumo O objetivo do presente estudo foi descrever os padrões de prática de atividade física e analisar suas variações conforme as características sociodemográficas de adolescentes de um município da região nordeste do Brasil. A amostra foi de 2.350 adolescentes do município de João Pessoa (PB). Foram determinadas as prevalências de atividade física e calculados os escores de prática (minutos/semana): geral e por tipos (esportes, exercícios físicos, deslocamento ativo e atividades recreativas). A regressão linear foi utilizada para estimar a contribuição relativa dos tipos de prática para o escore geral de atividade física. As atividades mais praticadas foram: deslocamentos (55,2%) e esportes (52,7%). As atividades que apresentaram maior capacidade explicativa para o escore geral de prática foram: esportes (38,1%) e exercícios físicos (21,8%). A capacidade explicativa dos esportes foi elevada em todos os subgrupos, exceto no sexo feminino. A prática de exercícios físicos contribuiu para as maiores variações no escore geral nos adolescentes do sexo feminino e de escolas privadas. As atividades recreativas e o deslocamento ativo tiveram a maior contribuição para o sexo feminino. Esportes e exercícios foram as atividades que mais contribuíram para explicar as variações no escore geral de prática.

Abstract The scope of this study was to describe the standards of physical activity practices and analyze its variations as sociodemographic characteristics of adolescents in a city of Northeastern Brazil. The sample consisted of 2,350 adolescents in the city of João Pessoa in the Brazilian State of Paraíba. The prevalence of physical activity was determined and the practice scores (minutes/week) calculated: general and types (sports, exercise, active commuting and recreational activities). Multiple linear regression was used to estimate the relative contribution of the types of practice for the general score of physical activity. The physical activities most practiced were active commuting (55.2%) and sports (52.7%). The activities that presented the greatest explanatory capacity for the overall score of practice were: sports (38.1%) and exercises (21.8%). The explanatory capacity of sports was increased in all subgroups, except in female patients. The practice of exercise contributes to the major changes in the general score in female adolescents from private schools. Recreational activities and active commuting had the largest contribution for the female gender. Sports and exercise were the activities that contributed the most to explain the changes in the general practice score.

RESUMEN

BACKGROUND: During pregnancy, the need for certain nutrients increases. This study assessed the prevalence and socio-demographic factors associated with dietary supplement use in a representative sample of pregnant women in Colombia. METHOD: Data for this study were obtained from a cross-sectional, nationally representative survey (ENSIN, 2010). A total of 1856 pregnant women, 13-49 years of age, were recruited. The use of prenatal dietary supplements (Vitamins A, C or E) was treated as a binary outcome (used at some time or never sued during pregnancy when prescribed by a doctor) in multinomial analyses. Sociodemographic data and associated factors were assessed by computer-assisted personal interview technology. RESULTS: Of the sample, 1123 women (68.6%) reported taking prenatal dietary supplements at some stage during their pregnancy. Most users had a high socioeconomic level (79.5%), were in their third trimester of pregnancy (79.5%), were 30-49 years of age (74.0%), and lived in the central region of Colombia (73.8%). The multivariate logistic regression showed that third trimester of pregnancy (OR 6.2;95% CI 4.0 to 9.3), high educational level (OR 2.3; 95% CI 1.5 to 3.4), high socioeconomic level -SISBEN IV or more- (OR 2.0; 95% CI 1.4 to 2.8), residence in the Atlantic region (north) (OR 2.6; 95% CI 1.7 to 3.6), Eastern region (OR 2.0; 95% CI 1.3 to 3.1), central region (OR 2.6; 95% CI 1.7 to 3.9), Pacific region (west) (OR 1.5; 95% CI 1.0 to 2.3), and belonging to the mestizo (others) ethnic group (OR 1.2; 95% CI 1.0 to 2.6), were all associated with a higher probability of dietary supplement intake. CONCLUSION: The prevalence of prenatal dietary supplements in pregnant women in Colombia was found to be substantial. The variables significantly associated with their use were educational level, socioeconomic level, trimester of pregnancy, geographic level and ethnic group. These results indicate the necessity of implementing new health policies that guarantee uniform access to nutritional supplements for all population sectors, especially in countries, such as Colombia, who are currently undergoing a process of nutritional transition.

RESUMEN

There is scarce data about prevalence of stroke in Brazil. The National Health Survey (PNS) is a community-based epidemiological survey, with a nationally representative sample to assess the absolute numbers with respective prevalence rates of stroke and post-stroke disabilities. It was estimated 2,231.000 stroke and 568,000 stroke cases with severe disabilities. The point prevalences was 1.6% and 1.4% in men and women, respectively. The prevalences of post-stroke disabilities were 29.5% for men and 21.5% for women. Stroke prevalence rates increased with aging, low education level, among people living in urban areas with no difference according to self-reported skin color. The degree of post-stroke disability was not statistically different according to sex, race, education level or living area. This new data from PNS show high stroke prevalence rates especially in older individuals without formal education and urban dweller, but the degree of stroke disability was not determined by the sociodemographic characteristics of the Brazilian population.

Há poucos dados sobre prevalência de acidente vascular cerebral (AVC) no Brasil. A Pesquisa Nacional de Saúde (PNS), um inquérito epidemiológico de base domiciliar, com amostra representativa nacional avaliou a prevalência de AVC no Brasil calculou o número absoluto estimado de pessoas com AVC e incapacidade por AVC e respectivas prevalências. Estimou-se 2.231.000 pessoas com AVC e 568.000 com incapacidade grave. A prevalência pontual foi 1,6% em homens e 1,4% em mulheres, e a de incapacidade 29,5% em homens e de 21,5% em mulheres. A prevalência aumentou com a idade, nos menos escolarizados, residentes da zona urbana sem diferenças pela cor da pele auto-declarada. O grau de incapacidade pós-AVC não foi estatisticamente diferente segundo sexo, raça, nível de educação ou área de moradia. Os dados inéditos da PNS mostram altas taxas de prevalências de AVC principalmente em indivíduos mais idosos, sem educação formal, moradores de centros urbanos porém o grau de incapacidade pelo ACV não foi determinado pelas características sociodemográficas da população brasileira.

RESUMEN

O objetivo deste artigo é avaliar o estado nutricional dos usuários dos restaurantes e refeitório populares de Belo Horizonte e identificar fatores associados ao excesso de peso. Estudo analítico transversal, conduzido em adultos de ambos os sexos, nos restaurantes e refeitório populares de Belo Horizonte. O excesso de peso, variável dependente, foi diagnosticado por meio do índice de massa corporal (IMC > 25 kg/m2) e correlacionado com as variáveis sociodemográficas e nível de atividade física. Os dados foram obtidos por meio da aferição direta do peso e da altura e de questionário semiestruturado. Participaram do estudo 1334 indivíduos, sendo a maioria do sexo masculino. A prevalência de excesso de peso foi de 42,9% entre os homens e 45,8% entre as mulheres. Os fatores positivamente associados ao excesso de peso foram: maior idade para ambos os sexos, possuir parceiro para as mulheres e menor prática de atividade física e classe socioeconômica mais elevada para os homens. A identificação dos fatores associados ao excesso de peso revela a necessidade da implantação de uma programação sistemática e eficaz de educação alimentar e nutricional para a prevenção e a remediação desse agravo, para que os restaurantes populares cumpram seu objetivo.

The scope of this article is to assess the nutritional status of users of low-budget restaurants and soup kitchens in Belo Horizonte and to identify factors associated with being overweight. It involved a cross-sectional analytical study conducted among adults of both sexes in low-budget restaurants and soup kitchens in Belo Horizonte. Being overweight was the dependent variable and was defined as body mass index (BMI) eŠ 25 kg/m2. This was correlated with socio-demographic variables and the level of physical activity. The data were obtained directly through weight and height measurement and a semi-structured questionnaire. The study involved 1334 individuals, the majority being male. The prevalence of being overweight was 42.9% among the men and 45.8% among the women. The following factors were positively associated with being overweight: being older for both sexes; having a partner for the women; taking less physical exercise and higher socioeconomic level for the men. Detection of factors associated with being overweight reveals that there is a need to implement an effective systematic program of dietary and nutritional education in order to prevent and remedy this condition, so that low-budget restaurants fulfill their objective.

RESUMEN

Factors associated with the incidence of malaria in the Vale do Amanhecer settlement, Juruena, Mato Grosso in 2005 were analyzed. Two hundred settlers of both genders and aged 18 years and above were interviewed. The prevalence of malaria reported in 2005 was 33%. The prevalence ratio showed that the highest prevalence of malaria was found in individuals involved in gold mining activities (67%); who came from non-endemic areas (43%); had inadequate knowledge about the time of greatest activity of the vector (71%); and who reported being outside after 5 p.m. (59%). It was concluded that in the Vale do Amanhecer settlement, factors such as occupation, origin, inadequate knowledge about where malaria is transmitted, inadequate knowledge about the time the mosquito usually bites and individual practices in relation to the peak period of mosquito activity were associated with malaria in 2005.

Analisaram-se fatores associados à ocorrência da malária no Assentamento Vale do Amanhecer, Juruena - Mato Grosso em 2005. Foram entrevistados 200 indivíduos assentados, de ambos os sexos e idade igual ou superior a 18 anos. A prevalência de malária referida em 2005 foi de 33,0%. A análise através da razão de prevalência mostrou que as maiores prevalências de malária foram nos indivíduos que exerciam atividade garimpeira (67,0%); procedentes de área não endêmica (43,0%); com conhecimento inadequado sobre o horário de maior atividade do vetor (71,0%) e indivíduos que referiram estar na roça após as 17:00 horas (59,0%). Concluiu-se que no Assentamento Vale do Amanhecer fatores como, ocupação, procedência, conhecimento inadequado sobre onde a malária é transmitida, horário que o mosquito costuma picar, e as atividades de cada indivíduo em relação ao horário de pico do vetor, mostraram-se associadas à malária em 2005.

RESUMEN

El objetivo de este trabajo fue comparar los valores de los estudiantes de una institución universitaria en función de las variables socio demográficas género, procedencia (colegio: privado - público y religioso - no religioso), religión (católica - no católica) y edad. Para la investigación se diseñó una escala autoaplicada de 55 valores, que se administró mediante una selección intencional a 3.384 estudiantes. De la escala de valores se derivaron cinco dimensiones: Cosmopolitas, Sociales, Instrumentales, Morales y Conservadores. Los resultados indicaron que las mujeres presentaron mayor valoración de las dimensiones valores Morales, Sociales y Conservadores, mientras que los hombres valoraron más la dimensión Cosmopolitas. Los estudiantes provenientes de colegios religiosos valoraron más la dimensión valores Conservadores. La variable socio demográfica de mayor influencia en las preferencias axiológicas fue el género y la dimensión de valores diferenciada por mayor cantidad de los factores socio demográficos evaluados fue aquella representada por valores conservadores.

The purpose of this study was to compare the values of university students as a function of socio-demographic variables such as: gender, kind of school (religious vs. non-religious; private vs. public), religion (Catholic - Non Catholic) and age. A self-administered scale of 55 values was designed for this research and it was used with a sample of 3.384 students selected intentionally. The values scale showed five dimensions: Cosmopolitan, Social, Instrumental, Moral and Conservative. Results indicated that women presented a higher appreciation of Moral, Social and Conservative values, whereas men valued more the Cosmopolitan values. The students that attended religious schools valued more the Conservative dimension. The socio demographic variable of major influence in the axiological preferences was gender and the value dimension differentiated by most socio-demographic factors was the Conservative.
