RESUMO
The persistence of symptoms for more than three months following infection with severe acute respiratory syndrome coronavirus 2 is referred to as "Long COVID". To gain a deeper understanding of the etiology and long-term progression of symptoms, this study aims to analyze the prevalence of Long COVID and its associated factors in a cohort of Brazilian adults and elders, twelve months after hospital discharge. An observational, prospective, and follow-up study was performed with a cohort of adults and older adults diagnosed with COVID-19 in 2020 in the State of Paraná, Brazil. Twelve months after hospital discharge, patients answered a phone questionnaire about the persistence of symptoms after three levels of exposure to COVID-19's acute phase (ambulatory, medical ward, and intensive care unit). According to the characteristics of participants, the prevalence of Long COVID-19 was calculated, and logistic regression analyses were conducted. We analyzed data from 1822 participants (980 adults [≥18-<60 years] and 842 older people [≥60 years]) across three exposure levels. The overall Long COVID prevalence was 64.2%. Long COVID was observed in 646 adults (55%; of which 326 were women) and 523 older people (45%; of which 284 were women). Females had a higher prevalence of long-term symptoms (52%) compared with men. The most common post-COVID-19 conditions in the 12-month follow-up were neurological (49.8%), followed by musculoskeletal (35.1%) and persistent respiratory symptoms (26.5%). Male individuals were less likely to develop Long COVID (aOR = 0.50). Other determinants were also considered risky, such as the presence of comorbidities (aOR = 1.41). Being an adult and having been hospitalized was associated with the development of Long COVID. The risk of developing Long COVID was twice as high for ward patients (aOR = 2.53) and three times as high for ICU patients (aOR = 3.56) when compared to non-hospitalized patients. Presenting clinical manifestations of digestive (aOR = 1.56), endocrine (aOR = 2.14), cutaneous (aOR = 2.51), musculoskeletal (aOR = 2.76) and psychological systems (aOR = 1.66) made adults more likely to develop Long COVID. Long COVID was present in a large proportion of people affected by the SARS-CoV-2 infection. Presence of Long COVID symptoms displayed a dose-response relationship with the level of disease exposure, with a greater prevalence of symptoms associated with the severe form in the acute period.
RESUMO
BACKGROUND: Despite the advancements in knowledge about health care for older adults, essential gaps persist regarding the effects of chronic diseases as epidemiological markers of the state of functional dependence. This study aimed to identify the prevalence of moderate and severe functional dependence in Brazilian older adults and its association with chronic diseases and verify the multimorbidity patterns by dependence status. METHODS: This cross-sectional analytical study used data from 11,177 community-dwelling Brazilian older adults from the 2013 National Health Survey conducted in Brazil. The dependent variables were moderate and severe functional dependence in basic activities of daily living (BADLs) and instrumental ADLs (IADLs). The independent variables were defined based on the questions applied to measure each morbidity in a self-reported manner and asked, "Has a doctor ever diagnosed you as having (each disease)? Multimorbidity was simultaneously considered present for older adults with ≥ 2 chronic morbidities. The association between functional dependence on BADLs and IADLs separately by severity and the independent variables was verified from crude and adjusted estimates of the point prevalence ratios and their 95% confidence intervals using the regression model Poisson with robust variance. To group diseases into patterns, exploratory factor analysis was used. RESULTS: The prevalences of moderate and severe BADL dependence were 10.2% (95% CI, 9.6-10.7) and 4.8% (95% CI, 4.4-5.2), respectively. Moderate and severe IADL dependence prevalences were 13.8% (95% CI, 13.1-14.4) and 15.6% (95% CI, 14.9%-16.2), respectively. When changing the condition from moderate to severe dependence in BADLs, in the presence of other mental illnesses and stroke, the probability of dependence increased more than four times in the case of other mental illnesses and more than five times for stroke. There was a linear trend for dependence severity, both moderate and severe, whereas, for severe dependence on IADLs, this same factor maintained a linear trend toward an increase in probability as the number of diseases simultaneously increased. CONCLUSIONS: Chronic diseases are associated with functional dependence, with greater emphasis on mental illnesses and stroke in severe disability, considering their acute adverse effects.

ABSTRACT Objective: To estimate the prevalence of adult smokers in the 26 capitals and the Federal District according to the Brazilian Deprivation Index (Índice Brasileiro de Privação - IBP). Methods: Dataset on smoking were obtained from the Surveillance of Risk and Protective Factors for Noncommunicable Diseases by Survey (Vigitel) system for the 26 capitals and the Federal District, in the period from 2010 to 2013. The IBP classifies the census sectors according to indicators such as: income less than ½ minimum wage, illiterate population and without sanitary sewage. In the North and Northeast regions, the census sectors were grouped into four categories (low, medium, high and very high deprivation) and in the South, Southeast and Midwest regions into three (low, medium and high deprivation). Prevalence estimates of adult smokers were obtained using the indirect estimation method in small areas. To calculate the prevalence ratios, Poisson models are used. Results: The positive association between prevalence and deprivation of census sector categories was found in 16 (59.3%) of the 27 cities. In nine (33.3%) cities, the sectors with the greatest deprivation had a higher prevalence of smokers when compared to those with the least deprivation, and in two (7.4%) there were no differences. In Aracaju, Belém, Fortaleza, João Pessoa, Macapá and Salvador, the prevalence of adult smokers was three times higher in the group of sectors with greater deprivation compared to those with less deprivation. Conclusion: Sectors with greater social deprivation had a higher prevalence of smoking, compared with less deprivation, pointing to social inequalities.
RESUMO Objetivo: Estimar as prevalências de adultos fumante nas 26 capitais e no Distrito Federal segundo o Índice Brasileiro de Privação. Métodos: Os dados sobre tabagismo foram obtidos junto ao sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito (Vigitel) para as 26 capitais e o Distrito Federal, no período de 2010 a 2013. O Índice Brasileiro de Privação classifica os setores censitários segundo indicadores como: renda menor que meio salário mínimo, população não alfabetizada e sem esgotamento sanitário. Nas regiões Norte e Nordeste, os setores censitários foram agrupados em quatro categorias (baixa, média, alta e muito alta privação) e, nas regiões Sul, Sudeste e Centro-Oeste, em três (baixa, média e alta privação). As estimativas de prevalências de adultos fumantes foram obtidas pelo método indireto de estimação em pequenas áreas. Para o cálculo das razões de prevalências, empregram-se modelos de Poisson. Resultados: A associação positiva entre a prevalência e a privação das categorias de setores censitários foi encontrada em 16 (59,3%) das 27 cidades. Em nove (33,3%) cidades, os setores de maior privação apresentaram maior prevalência de fumantes quando comparados aos de menor privação e, em duas (7,4%), não apresentaram diferenças. Em Aracaju, Belém, Fortaleza, João Pessoa, Macapá e Salvador, as prevalências de adultos fumantes foram três vezes maiores no grupo de setores com maior privação em relação aos de menor privação. Conclusão: Setores de maior privação social apresentaram maiores prevalências de tabagismo, comparados com menor privação, apontando desigualdades sociais.
RESUMO
ABSTRACT BACKGROUND: Multimorbidity can influence intensive care unit (ICU) admissions and deaths due to coronavirus disease (COVID-19). OBJECTIVE: To analyze the association between multimorbidity, ICU admissions, and deaths due to COVID-19 in Brazil. DESIGN AND SETTING: This cross-sectional study was conducted using data from patients with severe acute respiratory syndrome (SARS) due to COVID-19 recorded in the Influenza Epidemiological Surveillance Information System (SIVEP-Gripe) in 2020. METHODS: Descriptive and stratified analyses of multimorbidity were performed based on sociodemographic, ventilatory support, and diagnostic variables. Poisson regression was used to estimate the prevalence ratios. RESULTS: We identified 671,593 cases of SARS caused by COVID-19, of which 62.4% had at least one morbidity. Multimorbidity was associated with male sex, age 60-70 and ≥ 80 years, brown and black skin color, elementary education and high school, ventilatory support, and altered radiologic exams. Moreover, all regions of the country and altered computed tomography due to COVID-19 or other diseases were associated with death; only the northeast region and higher education were associated with ICU admission. CONCLUSION: Our results showed an association between multimorbidity, ICU admission, and death in COVID-19 patients in Brazil.

Despite the health, social and economic impact of arboviruses in French Guiana, very little is known about the extent to which infection burden is shared between individuals. We conducted a large multiplexed serological survey among 2697 individuals from June to October 2017. All serum samples were tested for IgG antibodies against DENV, CHIKV, ZIKV and MAYV using a recombinant antigen-based microsphere immunoassay with a subset further evaluated through anti-ZIKV microneutralization tests. The overall DENV seroprevalence was estimated at 73.1% (70.6-75.4) in the whole territory with estimations by serotype at 68.9% for DENV-1, 38.8% for DENV-2, 42.3% for DENV-3, and 56.1% for DENV-4. The overall seroprevalence of CHIKV, ZIKV and MAYV antibodies was 20.3% (17.7-23.1), 23.3% (20.9-25.9) and 3.3% (2.7-4.1), respectively. We provide a consistent overview of the burden of emerging arboviruses in French Guiana, with useful findings for risk mapping, future prevention and control programs. The majority of the population remains susceptible to CHIKV and ZIKV, which could potentially facilitate the risk of further re-emergences. Our results underscore the need to strengthen MAYV surveillance in order to rapidly detect any substantial changes in MAYV circulation patterns.

Introduction: Patients with Huntington-Like disorders (HLD) comprise a variety of allelic disorders sharing a Huntington phenotype. The hexanucleotide repeat expansion of the C9orf72 gene could explain part of the HLD etiology. We aimed to conduct a systematic review and meta-analysis looking for the frequency of the hexanucleotide repeat expansion of the C9orf72 gene in HLD patients. Methods: The protocol was registered on the International Prospective Register of Systematic Reviews database (PROSPERO) (registration number: CRD42018105465). The search was carried out in Medline, Scopus, Web of Science, and Embase in April 2018, and updated in July 2020. Observational studies reporting patients with HLD carrying the hexanucleotide repeat expansion in the C9orf72 gene were selected and reviewed; this process was duplicated. The cutoff threshold for considering the hexanucleotide expansion as a pathogenic variant was equal to or >30 G4C2 repeats. Cases with intermediate alleles with 20-29 repeat are also analyzed. Pooled frequency and 95% CI were calculated using random-effects models. Results: Nine out of 219 studies were selected, reporting 1,123 affected individuals with HLD. Among them, 18 individuals carried C9orf72 expansion, representing 1% (95% CI: 0-2%, I 2 = 0%) of the pooled frequency. Seven selected studies came from European centers, one was reported at a US center, and one came from a South-African center. We identified five individuals carrying intermediate alleles representing 3% (95% CI: 0-14%, I 2 = 78.5%). Conclusions: The frequency of C9orf72 unstable hexanucleotide repeat expansion in HLD patients is very low. Further studies with more accurate clinical data and from different ethnic backgrounds are needed to confirm this observation.

There were 68 people with a diagnosis of hypertension the 44.7 % and suspected hypertensive the 4.6 %, upon consolidation, a prevalence of 49.3 % was reached. Conclusion: the measurement of blood pressure in the population is essential for its control.
RESUMO
Resumo Este estudo teve como objetivo identificar a prevalência e fatores associados à hipertensão arterial (HA) em adultos quilombolas do Rio Grande do Sul (RS). Trata-se de um estudo transversal de base populacional, realizado em 2011, com 589 adultos responsáveis por domicílios e amostragem proporcional ao tamanho. O desfecho foi obtido com a pergunta: "Algum médico já lhe disse que você tem hipertensão?". Foi empregada regressão de Poisson, com variância robusta e entrada hierarquizada das variáveis. Por fim, foram calculadas as frações atribuíveis populacionais por componente (FAPC) para fatores modificáveis associados à HA. A prevalência autorreferida de HA foi de 38,3% (IC95% 31,4%-45,1%). A análise ajustada revelou associação do desfecho com faixa etária, escolaridade, consumo excessivo de álcool, circunferência da cintura acima do adequado e presença de diabetes. A análise dos FAPC revelou que, se os indivíduos tivessem maior escolaridade, a prevalência de HA seria reduzida. Diante da elevada prevalência de HA e da extrema vulnerabilidade social dessa população, políticas públicas que garantam seu acesso a direitos fundamentais (saúde, renda e escolaridade) poderiam ter impacto importante na diminuição desse desfecho.
Abstract The study sought to identify the prevalence of arterial hypertension (AH) and possible associated factors in adults residing in quilombola communities in the State of Rio Grande do Sul (RS). A transversal population-based study, carried out in 2011, included 589 adult households in quilombola communities in the State of RS, by sampling proportional to the size. The outcome was obtained by the question: "Has a doctor ever told you that you have hypertension?" Poisson regression with robust variance and hierarchical input variables were used. Finally, the population attributable fractions per component (PAFC) were calculated for modifiable factors associated to AH. The self-reported prevalence of AH was 38.3% (CI95% 31.4%-45.1%). Adjusted analysis revealed an association of the outcome with age group, education, excessive alcohol consumption, waist circumference and the presence of diabetes. PAFC analysis revealed that if the individuals had greater schooling, the prevalence of AH would be reduced. Given the high prevalence of AH and the extreme social vulnerability of this population, public policies that guarantee their access to fundamental rights (health, income and schooling) could have a significant impact in reducing this outcome.

INTRODUCTION: In Brazil, the prevalence and costs of pain will increase substantially with population ageing. Understanding of pain epidemiology is needed for the development of health care policies that can minimize this projected burden. OBJECTIVE: To investigate the prevalence of pain and associated factors at baseline of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). METHODS: Data were collected in public institutions of higher education/research (2008-2010). Pain in the past 30 days and pain attributed to psychological distress ("with psychological attributions"-PPA) were evaluated by the Clinical Interview Schedule-Revised (CIS-R). The independent t-test and χ2 test investigated associations between sociodemographic/clinical factors and each pain episode. Multivariable analyses including age, sex, leisure-time physical activity, depression, and arthritis/rheumatism, and factors showing univariate associations at the P < 0.10 level, were performed. RESULTS: Fifteen thousand ninety-five civil servants were included (52.1 ± 9.1 years, 54.4% female). The prevalence of any pain was 62.4% (95% confidence interval 61.6%-63.2%), and of PPA was 22.8% (95% confidence interval 22.2%-23.5%). Factors associated with any pain and PPA in multivariable analyses included age (odds ratio [OR] 0.97), female sex (OR 1.86-2.01), moderate and vigorous leisure-time physical activity (OR 0.60-0.84), excessive drinking (OR 0.68-0.83), depressive symptoms (OR 1.28-1.96), anxiety symptoms (OR 1.63-2.45), sleep disturbance (OR 1.62-1.79), and arthritis/rheumatism (OR 1.32-2.18). Nonroutine nonmanual occupation (manual occupation as reference), body mass index, and smoking were independently associated with either any pain or PPA. CONCLUSION: This study provided preliminary information on the epidemiology of pain at baseline of the largest Latin American cohort on chronic noncommunicable diseases.
RESUMO
BACKGROUND: Anemia during childhood is one of the biggest public health problems worldwide, including Brazil. Insufficient or abnormal production of hemoglobin, loss of iron and excessive destruction of red blood cells are the most common causes of anemia. Among the reasons of anemia, iron deficiency accounts for 50% of anemia cases in developing countries. Affected individuals present a wide range of clinical problems, including delayed neuropsychomotor progression, impaired cellular immunity and reduction of intellectual capacity. This study aimed to evaluate the prevalence of anemia in children attending public schools in the metropolitan region of Curitiba, Paraná, Brazil. METHOD: A retrospective study was conducted of 409 children aged 8-12 years old included in an extension project of the Universidade Federal do Paraná. The results of complete blood count and hemoglobin electrophoresis of all children were evaluated. Anemia was considered when the hemoglobin levels were <11.5 g/dL. RESULTS: The prevalence of anemia was found to be 2.2% of the population studied, with hypochromic microcytic anemia being the most common type. Seven children had sickle cell trait and one had ß-thalassemia. CONCLUSION: The prevalence of anemia in this study was considered normal according the World Health Organization classification, which is different from the data found in other Brazilian regions.

The aim of this cross-sectional study was to evaluate the prevalence of oral mucosal lesions (OMLs) and their association with crack/cocaine addiction in men. Clinical oral examination was performed in 161 adult male patients at the School of Dentistry of the Federal University of Bahia, Brazil. Crack/cocaine addiction was determined from the medical records, and all drug-addicted individuals used both crack and cocaine. All participants (40 crack/cocaine-addicted men and 121 non-addicted men) underwent a systematic evaluation of the lips, labial mucosa, commissures, buccal mucosa and sulcus, gingiva and alveolar ridge, tongue, floor of the mouth, and soft and hard palate by a single examiner. Bivariate and regression analyses were conducted to assess for the presence of OMLs and the association of OMLs with crack/cocaine addiction. OMLs were found in 22 participants with a significantly greater prevalence in the crack/cocaine-addicted group (25 vs. 9.9%; p = 0.01). The most prevalent types of lesions in the addicted group were traumatic ulcer and actinic cheilitis (7.5% for each) followed by fistulae associated with a retained dental root (5%). After adjusting for covariates, crack/cocaine addiction was significantly associated with OMLs (OR = 2.87; 95% CI = 1.08-7.67; p = 0.03). The prevalence of OMLs was higher in crack/cocaine-addicted individuals, and crack/cocaine addiction was significantly associated with OMLs. A public health program aimed at the early diagnosis and treatment of OMLs is vital to improving the oral health status of individuals addicted to crack/cocaine.

Conocer la prevalencia de la esquizofrenia y trastornos afines tiene una importancia relevante en la investigación epidemiológica y en la planificación de servicios. Sin embargo, existe una gran variabilidad en los resultados obtenidos en las diferentes investigaciones. El objetivo de este artículo es hacer una revisión crítica de los aspectos metodológicos de los estudios epidemiológicos que pueden influir en la medición de la prevalencia de esquizofrenia y trastornos afines y ofrecer una serie de recomendaciones generales para su medición. Se revisan 53 estudios epidemiológicos que relatan 76 tasas de prevalencia que oscilan entre 1 y 45 por 1000 habitantes. Se han encontrado seis factores metodológicos que creemos que están influyendo en la variabilidad de la medida de prevalencia de la esquizofrenia: 1. el tipo de prevalencia según el periodo de tiempo, siendo la más utilizada la prevalencia puntual; 2. el rango de edad de la población de estudio, siendo lo más frecuente incluir a personas mayores de 18 años; 3. el ámbito de detección de los casos más frecuentemente utilizado es la población general; 4. las clasificaciones de enfermedades utilizadas son la CIE y la DSM en similar proporción; 5. la categoría diagnóstica incluida frecuentemente en los estudios es el grupo de psicosis no afectivas; 6. el método de valoración diagnóstica más utilizado es la entrevista CIDI. Conclusión Consideramos que llegar a un consenso internacional para homogeneizar los aspectos metodológicos en los estudios epidemiológicos para calcular cifras de prevalencia de esquizofrenia nos facilitará la comparación de sus resultados.
Epidemiologic research plays a very relevant role to know the prevalence of schizophrenia. However, sometimes data from different studies are compared without taking into account some methodological questions that influence the results. This paper reviews different methodological factors that influence variability of rates in schizophrenia prevalence. Also, we provide some generic recommendations for measuring prevalence. We have revised 52 studies which offer prevalence rates of schizophrenia. A big difference appears in the prevalence rates of schizophrenia which range between 1 to 45 per 1000 inhabitants. The factors founded can be summarized as follows: 1. type of prevalence; 2. denominator population; 3. place of selection of cases; 4. classification issue; 5. diagnoses categories and 6. methods of diagnoses. In conclusion, in the epidemiological studies about schizophrenia prevalence we have to take into account the methodological factors involved in order to interprete and compare results from different studies.
RESUMO
Introduction. Habit is any act acquired through experience and performed regularly and unconsciously. Parafunctional habits are resulting from the perversion of a normal function, acquired by repeated practice of an act that is not functional or necessary, may be signs of adjustment problems or inappropriate emotional expression. Its importance lies in the fact that they can interfere with the development of dental occlusion. Objective. To evaluate the prevalence of parafunctional oral habits and their possible association with the type of family, in a group of preschool children from eastern Mexico City. Methodology. Observational, descriptive and cross-sectional study was carrying on. Preschool children group and their parents were surveyed before an examiner calibration (k =0.87, p=0.001). The detection of different parafunctional habits was conducted in two stages: 1) application of a parent questionnaire and 2) clinical assessment of the child. Results and discussion. 57.7 percent of the studied population had at least one parafunctional oral habit. Onycophagia habit was the most prevalent. The relationship between prevalence of parafunctional habits with family type was significant (X2=87.439, p=0.0001). Conclusions. The prevalence of parafunctional habits was high which was associated with family type also the most frequent parafunctional habit onycophagia.
Introducción. Un hábito es cualquier acto adquirido mediante la experiencia y realizado regular e inconscientemente. Los hábitos bucales parafuncionales son los que resultan de la alteración de una función normal, o los que se adquieren por la práctica repetida de un acto que no es funcional ni necesario, pudiendo ser signos de problemas de adaptación o de expresión emocional inadecuada. Su importancia radica en el hecho de que pueden interferir con el desarrollo de la oclusión dental, razón por la cual el objetivo del presente estudio fue evaluar la prevalencia de hábitos bucales parafuncionales y su posible relación con la estructura familiar, en un grupo de preescolares de un Centro de Desarrollo Infantil del oriente de la Ciudad de México. Metodología. El estudio fue de carácter observacional, descriptivo y transversal, en el que 111 preescolares y sus padres fueron encuestados previa calibración de una examinadora (k=0.87, p=0.001). La detección de los diferentes hábitos bucales parafuncionales se realizó en dos etapas: 1) aplicación de un cuestionario al padre de familia y 2) valoración clínica del niño. Resultados y discusión. El 57.7 por ciento de la población estudiada presentó, al menos un hábito bucal parafuncional. La onicofagia fue el hábito de mayor prevalencia. La relación entre la prevalencia de hábitos parafuncionales con la estructura familiar resultó ser significativa (X2=87.439, p=0.0001). Conclusiones. La prevalencia de hábitos bucales parafuncionales fue alta la cual estuvo relacionada con la estructura familiar, asimismo, el hábito parafuncional más frecuente fue la onicofagia.

El objetivo de esta investigación es determinar la prevalencia de queilitis actínica (QA) y factores asociados en trabajadores expuestos a radiación UV solar en la ciudad de Talca, Chile. Se examinaron 151 trabajadores, donde un 16.6 por ciento presentó QA. Todas las lesiones se presentaron en el labio inferior. El 40 por ciento de los casos poseía una edad entre 50 y 59 años y el 96 por ciento de los pacientes diagnosticados trabajaba más de 6 horas diarias expuestos al sol. El 56 por ciento de los diagnósticos de QA presentaron un historial 20 o más años totales de exposición a radiación UV por motivos laborales. El 56 por ciento de los casos de QA presentaron antecedentes de hábito de fumar. Los principales signos presentes en los casos de QA fueron la sequedad (100 por ciento), esfumación del margen del bermellón (88 por ciento) y el edema labial (84 por ciento). La mayoría de las lesiones fueron asintomáticas (60 por ciento).
The objective of this research is to determine the prevalence of actinic cheilitis (AC) and associated factors in workers exposed to solar UV radiation in the city of Talca (Chile). A total of 151 workers, of which 16.6 percent exhibited AC, were examined. All lesions appeared on the lower lip. The 40 percent of cases aged between 50-59 years and 96 percent of patients diagnosed worked up to 6 hours daily exposed to the sun. 56 percent of the diagnoses of AC had a history of 20 or more years of exposure to UV radiation for work. 56 percent of cases of AC had a history of smoking. Major signs present in the AC cases were the dryness (100 percent), blurred demarcation between the lip vermilion border and the skin (88 percent) and labial edema (84 percent). Most lesions were asymptomatic (60 percent).

OBJETIVO: Verificar a prevalência e os fatores associados aos hábitos de sucção não nutritiva em crianças pré-escolares matriculadas em creches e pré-escolas de Natal (RN). MÉTODOS: Foi conduzido um estudo transversal com 1.190 crianças de ambos os sexos na faixa etária de 3 a 5 anos, matriculadas em creches e pré-escolas de Natal. Não foram incluídas no estudo crianças com fendas labiopalatinas, desordens temporomandibulares, ou aquelas submetidas a tratamento ortodôntico e/ou ortopédico; também não fizeram parte da amostra instituições de ensino especializadas em crianças portadoras de deficiência. Utilizou-se um questionário estruturado, respondido pelos pais ou responsável, com dados sobre a instituição, sexo e idade das crianças, escolaridade dos pais e questões relacionadas aos hábitos. A análise dos dados foi realizada através do teste do qui-quadrado e a regressão logística. RESULTADOS: Obteve-se prevalência de 40,2 por cento de hábitos de sucção não nutritiva, dos quais 27,7 por cento eram de sucção de chupeta e 12,5 por cento de dedo. Os hábitos de sucção apresentaram maior percentual para o sexo feminino, destacando-se a sucção de dedo (p = 0,02); em crianças com menos idade destacou-se a sucção de chupeta (p = 0,0006). Observou-se maior frequência de sucção de chupeta e de dedo, respectivamente, para o nível superior (p < 0,05) e fundamental (p < 0,05) de escolaridade dos pais. A regressão logística demonstrou que a menor idade dos indivíduos (p = 0,033) e o nível médio de escolaridade dos pais (p = 0,035) são fatores independentes para a persistência dos hábitos. CONCLUSÃO: Verificou-se uma alta prevalência de realização dos hábitos de sucção não nutritiva, apresentando como fatores de destaque a menor idade das crianças e o nível médio de escolaridade dos pais.
OBJECTIVE: To verify the prevalence and factors associated with nonnutritive sucking habits in preschool-aged children attending daycare centers and preschools in Natal, Brazil. METHODS: A cross-sectional study was conducted with 1,190 children of both sexes, aged 3 to 5 years, enrolled in daycare centers and preschools in Natal, Brazil. Exclusion criteria were: children with cleft lip and palate, temporomandibular joint disorders, or submitted to orthodontic and/or orthopedic treatment; as well as institutions specialized in children with disabilities. Parents or guardians answered a structured questionnaire providing information on the institution, children's sex and age, parents' educational level, and habit-related questions. Data analysis was performed using the chi-square test and logistic regression. RESULTS: A prevalence of 40.2 percent of nonnutritive sucking habits was obtained; of these, 27.7 percent were pacifier-sucking and 12.5 percent were finger-sucking habits. Girls showed a higher percentage of sucking habits, especially finger sucking (p = 0.02); younger children showed a higher prevalence of pacifier-sucking habits (p = 0.0006). A higher frequency of pacifier- and finger-sucking habits was associated, respectively, with parents' higher education (p < 0.05) and elementary education (p < 0.05). Logistic regression revealed that younger individuals (p = 0.033) and secondary education level of parents (p = 0.035) are independent factors for habit persistence. CONCLUSION: A high prevalence of nonnutritive sucking habits was verified, highlighting younger age groups and secondary education level of parents as important associated factors.
