Incidence of Dental Caries and Associated Factors in the School Period in a Municipality in Southern Brazil

Abstract Objective: To estimate the incidence of dental caries and associated factors in the school period from six/seven to ten years of age. Material and Methods: A longitudinal study involving 168 children was followed up between 2015 and 2019 in the municipality of Palhoça, Brazil. The dependent variable was the caries incidence rate in the mixed dentition. The independent variables included information regarding demographic and socioeconomic status. Multivariate analyzes were carried out using Poisson Regression with a robust estimator. Variables with p <0.20 in the bivariate analysis were included in the adjusted model. Relative risks were estimated, as well as 95% confidence intervals. Results: Of 168 followed schoolchildren, 32 developed the disease, providing an incidence rate of 19.0%. Female children had a 10% higher risk [RR = 1.10 (95% CI 1.03; 1.18)] of developing caries than males. Also, children born from fathers with ≤ 8 years of schooling at baseline had a 9% higher risk [RR = 1.09 (95% CI 1.01; 1.16)] of developing dental caries compared to fathers with higher education. Conclusion: The incidence of dental caries in a four-year period was 19.0%. Females and children born from fathers with a lower level of education showed higher incidence rates.

Prenatal, neonatal and postnatal factors and the developmental defects of dental enamel / Fatores pré-natais, neonatais e pós-natais e defeitos de desenvolvimento do esmalte dentário

ABSTRACT Objective: To estimate the prevalence of developmental defects in dental enamel and its possible association with prenatal, neonatal and postnatal conditions in six-year-old schoolchildren in a southern Brazilian municipality. Methods: A cross-sectional study was conducted involving 655 six-year-old schoolchildren. Sociodemographic and health data were collected through interviews with mothers and children's oral examinations at schools. Multivariate analyses were performed using Poisson regression with robust estimator. Results: The prevalence of developmental defects of enamel was 44.0%. Demarcated opacities were the most prevalent, followed by diffuse opacities. Late pregnancy, maternal schooling less than eight years, female gender and child's white skin color were independently associated with the prevalence of demarcated opacities. Conclusions: The prevalence of developmental defects in dental enamel was 44.0%. Late pregnancy, maternal schooling less than eight years, female gender and child's white skin color were associated with the prevalences.

Artificial juice and soft drink consumption was 7% and 8% higher in public school students respectively and 6% higher in bottle-fed children. Most schoolchildren consumed the ultra-processed foods assessed once or twice a week. Consumption was associated with the independent variables assessed.

A carga de doença por COVID-19 em Florianópolis, Santa Catarina, Brasil, no período de um ano / The burden of disease due to COVID-19 in Florianópolis, Santa Catarina, Brazil, over a one-year period

Resumo A COVID-19 gerou impacto na sociedade com elevados índices de morbidade e mortalidade. A utilização de indicador epidemiológico que estime a carga de doença, agregando em uma medida a mortalidade precoce e os casos não fatais, tem potencial de auxiliar no planejamento de ações adequadas em diferentes níveis de atenção à saúde. O objetivo deste artigo é estimar a carga de doença por COVID-19 em Florianópolis/SC de abril de 2020 a março de 2021. Foi realizado um estudo ecológico com dados de notificação e óbitos por COVID-19 no período de 12 meses. Utilizou-se o indicador de carga denominado Anos de Vida Perdidos Ajustados por Incapacidade (DALY), obtido pela soma dos Anos de Vida Perdidos (YLL) com os Anos Vividos com Incapacidade (YLD). Foram incluídos 78.907 casos de COVID-19 confirmados. Desses, 763 evoluíram a óbito no período estudado. No total, foram estimados 4.496,6 DALYs, taxa de 883,8 DALYs/100.000 habitantes. No sexo masculino, foram 2.693,1 DALYs, taxa de 1.098,0 DALYs/100.000 homens. Em mulheres, foram 1.803,8 DALYs, taxa de 684,4 DALYs/100.000 mulheres. A faixa etária mais acometida em ambos os sexos foi de 60 a 69 anos. Foi alta a carga de COVID-19 na cidade estudada. As maiores taxas foram encontradas no sexo feminino e na faixa-etária de 60-69 anos.

Abstract COVID-19 has had a powerful impact on society with high rates of morbidity and mortality. The use of an epidemiological indicator that estimates the burden of a disease by aggregating early mortality and non-fatal cases in a single measure has the potential to assist in the planning of more appropriate actions at different levels of health care. The scope of this article is to estimate the burden of disease due to COVID-19 in Florianópolis/SC from April 2020 through March 2021. An ecological study was carried out with data from notification and deaths by COVID-19 in the period of 12 months. The burden indicator called Disability-Adjusted Life Years (DALY) was used, obtained by adding the Years of Life Lost (YLL) to the Years of healthy life lost due to disability (YLD). A total of 78,907 confirmed COVID-19 cases were included. Of these, 763 died during the period under study. Overall, 4,496.9 DALYs were estimated, namely a rate of 883.8 DALYs per 100,000 inhabitants. In males, there were 2,693.1 DALYs, a rate of 1,098.0 DALYs per 100,000 males. In women, there were 1,803.8 DALYs, a rate of 684.4 DALYs per100,000 women. The age group most affected in both sexes was 60 to 69 years. The burden of COVID-19 was high in the city studied. The highest rates were in females and in the 60-69 age group.

First Thousand Days of Child Life and the Development of Risk Factors for Malocclusions

ABSTRACT Objective: To identify the association between individual and socioeconomic factors during the first thousand days of the child's life and the occurrence of risk behaviors for the development of malocclusions. Material and Methods: Cross-sectional study. A sample of 655 6-year-old schoolchildren and families was included. Interviews with mothers were performed at home. The dependent variables were risk behaviors to the development of malocclusions. Independent variables were socioeconomic conditions, aspects of gestation, birth and health of the child up to two years of age. Bivariate and multivariate analyzes were performed through Poisson regression. Results: Maternal education of less than eight years was independently associated with the interruption of exclusive breastfeeding until the fourth month (PR=1.58 CI 95%; 1.07; 2.37). Occupation of the mother with income [PR=1.26; 1.02; 1.56)], occupation of the father without income [PR=1.46 (1.01; 2.14)] were associated fwith interruption of breastfeeding until the sixth month. Pregnancy in adolescence [PR=0.83 (0.70; 0.98)] and nursery attendance [PR=1.15 (1.02; 1.28)] were associated with bottle use. Nursery attendance [PR=1.27 (1.01; 1.59)], hospitalization in the first 29 days of life [PR=1.34 (1.01; 1.80)], occurrence of reflux [PR=1.30 (1.01; 1.70)] were associated with pacifier using. Conclusion: Variables related to the period of the first thousand days of life are associated with higher risk behaviors for the occurrence of malocclusions.

Prevalence of allergic rhinitis symptoms and associated factors in six-year-old children in a municipality in southern Brazil / Prevalência de sintomas de rinite alérgica e fatores associados em crianças de seis anos em um município do sul do Brasil

ABSTRACT Objective: To estimate the prevalence of allergic rhinitis symptoms and associated factors in six-year-old children. Methods: Cross-sectional epidemiological study involving 956 six-year-old schoolchildren from Palhoça, Santa Catarina, Brazil. Home interviews were conducted with mothers in which socio-demographic and house environmental conditions information were obtained, and the International Study of Athma and Allergies in Childhood (ISAAC) questionnaire for allergic rhinitis symptoms was applied. Bivariate and multivariate hierarchical analyses were performed using Poisson regression with a robust estimator. Results: The prevalence of allergic rhinitis symptoms was 21.7%. Children whose mothers had over 8 years of education, or who had air conditioning equipment in the house, or whose bedroom walls presented mold or moisture showed statistically significant and independent 5% higher prevalence of allergic rhinitis. Similarly, children of smoker mothers or those who lived with fur or feather animals indoors showed a 4% higher prevalence. Conclusion: Significant associations were observed between socio-demographic factors and environmental conditions in child's home and allergic rhinitis symptoms in children aged six years.

Fatores perinatais associados à sepse neonatal precoce em uma maternidade-escola do sul do Brasil / Perinatal factors associated with early neonatal sepsis in the maternity ward of a teaching hospital in southern brazil

Introdução: Sepse neonatal é uma condição potencialmente fatal, que constitui um problema de saúde pública de impacto global e é responsável por taxas expressivas de morbidade e mortalidade. O objetivo deste artigo é estimar os fatores associados à sepse neonatal precoce em uma maternidade-escola do sul do Brasil. Métodos: Realizou-se estudo de caso-controle para observar eventual associação entre fatores relacionados à sepse neonatal precoce e características clínicas e sociodemográficas maternas e fatores perinatais dos recém-nascidos, utilizando-se dados de prontuários de pacientes no período entre 2014 e 2017. A amostra foi composta por 293 binômios mãe/recém-nascido, sendo 1 caso para 2 controles. Todas as variáveis com valores de p< 0,05 na análise bivariada foram incluídas em uma análise multivariada por meio de Regressão Logística. Resultados: Idade gestacional menor que 37 semanas (OR 19,6 IC 95% 5,3; 73,0) (p<00,1) e presença de fator de risco para Streptococcus agalactiae beta hemolítico (SGB) (OR 5,1 IC 95% 1,2; 21,8) (p=0,027) foram as exposições independentemente associadas à sepse neonatal precoce. Conclusão: Identificou-se maior chance de desenvolver sepse neonatal precoce quando prematuridade e fatores de risco maternos para SGB estão presentes. Assim, medidas mais eficazes de prevenção e controle desses fatores são de extrema importância.

Introduction: Neonatal sepsis is a potentially fatal condition that constitutes a public health problem worldwide, being responsible for significant rates of morbidity and mortality. The objective of this study was to identify factors associated with early neonatal sepsis in the maternity ward of a teaching hospital in Southern Brazil. Methods: We conducted a case-control study to identify if factors related to early neonatal sepsis are associated with maternal clinical and sociodemographic characteristics and perinatal factors of infants, using data from patient records between 2014 and 2017. The sample consisted of 293 mother/newborn binomials, 1 case for 2 controls. All variables with p-values < 0.05 in the bivariate analysis were included in a multivariate analysis using logistic regression. Results: A gestational age < 37 weeks (odds ratio [OR] 19.6; 95%CI 5.3; 73.0) (p < 00.1) and the presence of a risk factor for beta-hemolytic Streptococcus agalactiae (GBS) (OR 5.1; 95%CI 1.2; 21.8) (p = 0.027) were independently associated with early neonatal sepsis. Conclusions: Prematurity and the presence of maternal risk factors for GBS increase the likelihood of developing early neonatal sepsis. Thus, more effective measures to prevent and control these factors are extremely important.

RESUMO: Objetivo: Realizar a adaptação transcultural e a validação, no contexto cultural brasileiro, do instrumento de impacto da obesidade Patient-Reported Outcomes in Obesity (PROS). Métodos: O processo de adaptação transcultural contou com a tradução do idioma original, inglês, para o português, executada por dois tradutores qualificados e independentes. A retrotradução foi realizada por dois professores de inglês, nativos, sem qualquer conhecimento médico nem da escala original. Um comitê de especialistas foi composto de pesquisadores para avaliar as equivalências semântica, idiomática, experiencial e conceitual. O pré-teste da versão brasileira, denominada PROS-Br, foi realizado com dez indivíduos adultos com obesidade. Para a avaliação das propriedades psicométricas, foi realizado um estudo epidemiológico de delineamento transversal. A população foi composta de 120 indivíduos adultos com obesidade, brasileiros, presentes para consulta médica em ambulatório-escola. Para análises psicométricas, foram utilizadas a Teoria de Resposta ao Item e análise fatorial com extração de componentes principais. Para aferição da confiabilidade foi utilizado o indicador α-Cronbach. Resultados: Na análise de confiabilidade, o PROS-Br apresentou α-Cronbach de 0,82. Dois fatores explicaram 58,3% da variância total na análise de componentes principais, envolvendo aspectos comportamentais e físicos. As curvas da Teoria de Resposta ao Item mostraram que todas as perguntas apresentam características discriminatórias, apontando para a adequação da versão brasileira proposta. Conclusão: A versão brasileira mostrou-se válida e confiável para aferir a qualidade de vida de indivíduos com obesidade, possibilitando desenvolver estratégias de intervenção, planejamento e execução de ações nos serviços e na política pública de saúde.

ABSTRACT: Objective: To perform a cross-cultural adaptation and validation in the Brazilian cultural context of questionnaire Patient-Reported Outcomes in Obesity (PROS). Methods: The cross-cultural adaptation process involved the translation from original English language into Brazilian Portuguese by two qualified and independent translators. The back-translation was performed by two English language teachers who were native speakers, without any medical knowledge of the original scale. An expert committee was created with researchers to assess semantic, idiomatic, experiential and conceptual equivalence. The pre-test of the Brazilian version, named PROS-Br, was carried out with ten adults with obesity. To assess the psychometric properties of the instrument, a cross-sectional epidemiological study was carried out. The population consisted of 120 Brazilian adults with obesity who went to the appointment at a school-clinic. The Item Response Theory and Factor Analysis with Principal Component Extraction was used for the psychometrics analysis. To measure reliability, the α-Cronbach indicator was used. Results: In the reliability analysis, α-Cronbach was 0.82. Two factors explained 58.3% of the total variance in the principal component analysis, involving behavioral and physical aspects. Item Response Theory curves showed that all questions have discriminatory characteristics, pointing to the adequacy of the proposed version. Conclusion: The Brazilian version was proven valid and reliable to measure the quality of life of individuals with obesity, allowing one to develop intervention strategies, plan and execute actions at services and for public health policies.

Association between prenatal and neonatal factors and occurrence of asthma symptoms in six-year-old children / Associação entre fatores pré-natais e neonatais e ocorrência de sintomas de asma em crianças aos seis anos de idade

Abstract The objective was to estimate association between prenatal and neonatal factors and asthma symptoms in children at six years of age. A cross-sectional study using secondary data from a cohort study with a sample of 578 children was carried out. Data were analyzed using three levels hierarchical Poisson Regression. Of the 578 children included in the study, 43.4% (95% CI 39.4; 47.4) had asthma symptoms. The variables with significantly higher prevalence of symptoms and asthma at six years of age were: male gender, with 5% higher prevalence (PR = 1.05 95% CI 1.01; 1.11) (p = 0.043); children of pregnant women presenting infectious diseases with 7% higher prevalence (PR = 1.07; 95% CI 1.02; 1.13) (p = 0.011); children who were not breastfed, with a 12% higher prevalence (PR = 1.12; 95% CI 1.02; 1.24) (p = 0.022) and children with respiratory problems in the first month of life, with a 14% higher prevalence (PR = 1.14; 95% CI 1.01; 1.29) (p = 0.033). It could be concluded that male gender, time-independent breastfeeding deprivation and respiratory problems in the first month of life were independently associated with asthma symptoms at six years of age. The occurrence of infectious diseases during pregnancy was the only factor with intrauterine physiology that was associated with the occurrence of asthma symptoms at six years of age.

Resumo O objetivo foi estimar a associação entre fatores pré-natais e neonatais e sintomas de asma em crianças aos seis anos de idade. Foi realizado um estudo epidemiológico transversal com dados secundários provenientes de estudo de coorte com amostragem de 578 crianças. Os dados foram analisados por meio de regressão de Poisson. Do total de 578 crianças incluídas no estudo, 43,4% (IC 95% 39,4; 47,4) apresentavam sintomas de asma. As variáveis com prevalências significativamente maiores de sintomas de asma aos seis anos de idade foram: sexo masculino, com prevalência 5% maior (RP = 1,05 IC 95% 1,01; 1,11) (p = 0,043); crianças de gestantes portadoras de doenças infecciosas, com prevalência 7% maior (RP = 1,07; IC 95% 1,02; 1,13) (p = 0,011); crianças que não foram amamentadas, com prevalência 12% maior (RP = 1,12; IC 95% 1,02; 1,24) (p = 0,022), e crianças com problemas respiratórios no primeiro mês de vida, com prevalência 14% maior (RP = 1,14; IC 95% 1,01; 1,29) (p = 0,033). Concluiu-se que sexo masculino, privação de amamentação, independentemente do tempo, e problemas respiratórios no primeiro mês de vida foram associados de forma independente aos sintomas de asma aos seis anos de idade. A ocorrência de doenças infecciosas durante a gravidez foi o único fator fisiológico intra-uterino associado à ocorrência de sintomas de asma aos seis anos de idade.

Accuracy of neck circumference for diagnosing overweight in sixand seven-year-old children

Abstract Objective: To estimate the accuracy of neck circumference measurement as a method of diagnosing excess weight of six and seven-year-old children. Methods: 1026 six and seven-year-old children were included and anthropometric data were collected using cut-off points for the Body Mass Index (BMI) Z-score, in addition to the measurement of their neck circumference in centimeters. Pearson's correlation coefficient was used to assess the correlation between neck circumference and BMI. Sensitivity, specificity, positive and negative predictive values were calculated. The Receiver Operating Characteristic curve was used to measure the accuracy of neck circumference as a diagnostic method for excess weight. Results: A positive linear correlation value was observed between neck circumference and BMI 0.572 (p < 0.001). The accuracy value of the global ROC curve was 0.772 (p < 0.001). Sensitivity and specificity showed low values, but high positive predictive values were observed, especially between measures of 30 and 31 cm. Conclusion: Neck circumference showed accuracy of 77.2% as a diagnostic method for overweightness in six and seven-year-old children.

Prevalence and Associated Factors of Dental Trauma in Six-Year-Old School-Children

ABSTRACT Objective: To estimate the prevalence and associated factors of dental trauma in 6-year-old school children in the city of Palhoça, Brazil. Material and Methods: Cross-sectional study nested in a cohort study. It involved a representative sample of school children born in 2009, residing in the municipality and regularly enrolled in public and private schools (n = 1,102). Clinical data were obtained through oral exams. To evaluate the incisal overjet, the distance in millimeters was measured horizontally from the labial surface of the lower central incisor to the labial surface of the upper incisor. Bivariate analyses were performed using the Chi-square test, with a p-value <0.05 considered statistically significant. Multivariate analyses using Poisson Regression were performed to identify independent associations between the prevalence and the independent variables studied. Results: Prevalence of dental trauma was 4.2% (95% CI 3.0-5.4). Dental trauma was statistically associated with studying in a private school (PR = 1.03; 95% CI 1.01-1.06) (p=0.016) and with inadequate lip coverage (PR = 1.08; 95% CI 1.01-1.14) (p=0.016). Conclusion: The prevalence of 4.2% of dental trauma in six-year-old children, associated with inadequate and greater lip coverage in children from private schools should be taken into account, since most teeth at this stage are newly erupted.

The Influence of the First Thousand Days of Life on Establishing Determinant Behaviors for Dental Caries in Childhood

ABSTRACT Objective: To study the influence of the first thousand days of life on establishing determinant behaviors for dental caries in childhood. Material and Methods: Longitudinal retrospective study involving 664 children born in 2009 living in a southern Brazilian municipality was carried out. Data was collected through interviews with mothers and through child's health card. Dependent variables were 1) tooth brushing onset after two years of age; 2) absent tooth brushing or once a day; 3) tooth brushing without adult supervision; 4) not having gone to the dentist until the age of 6; and 5) seek for dental services due to toothache at 6 years of age, over the last 30 days. Bivariate and multivariate analyses were performed using Poisson Regression to estimate relative risks (RR) and respective confidence intervals at the 95% accuracy level. Results: Mothers with lower schooling at child's birth presented a higher risk of "child's tooth brushing onset only after two years of age", "brushing the teeth once a day only or not brushing" and with "child not having gone to the dentist until the age of 6". Mothers who did not have a job when the child was born were associated with "not having gone to the dentist until the age 6". Children with gastroesophageal reflux who underwent hospitalization for more than 2 days under age 2 were associated with "seeking dental services because of pain at 6 years of age over the last 30 days". Conclusion: Higher risks of some determinant behaviors related to dental caries were associated with variables of the period of the first thousand days of life.

Two criteria of oral glucose tolerance test to diagnose gestational diabetes mellitus

SUMMARY OBJECTIVE To evaluate two different criteria, one or two cut-off values, of oral glucose tolerance test with 75g of glucose for the diagnosis of gestational diabetes mellitus. METHODS A cross-sectional study involving 120 records of pregnant women who received prenatal care at the service of a Brazilian university was carried out. Bivariate analysis of obstetric and perinatal outcomes was performed using the chi-square test. RESULTS Considering criterion I, 12.5% of patients were diagnosed with gestational diabetes mellitus. Patients were 3.57 times more likely to have a large fetus for the gestational age at birth (p=0.038). Using criterion II, gestational diabetes mellitus was diagnosed in 5.8% of patients, macrosomia was 7.73 times more likely to be found in the presence of gestational diabetes mellitus (p=0.004), and a large fetus for the gestational age at birth was 8.17 times more likely (p=0.004). CONCLUSIONS There was a difference in the prevalence of gestational diabetes mellitus between the two criteria analyzed. The new criterion proposed increased prevalence.

RESUMO OBJETIVO Avaliar dois critérios distintos, um ou dois valores de corte, do teste oral de tolerância à glicose com 75 g de glicose para o diagnóstico de diabetes mellitus gestacional. Métodos Estudo transversal envolvendo 120 prontuários de gestantes que realizaram pré-natal em um ambulatório de uma universidade brasileira. Análise bivariada dos resultados obstétricos e perinatais foi realizada pelo teste do qui-quadrado. Resultados Considerando o critério I, 12,5% das pacientes foram diagnosticadas com diabetes mellitus gestacional. As pacientes apresentaram uma chance 3,57 maior de ter um feto grande para a idade gestacional (p=0,038). Utilizando o critério II, o diabetes mellitus gestacional foi diagnosticado em 5,8% das pacientes. Mediante esse critério diagnóstico, a chance de macrossomia foi 7,73 vezes mais provável na presença de diabetes mellitus gestacional (p=0,004) e a chance de um feto grande para a idade gestacional foi 8,17 vezes maior de ocorrer (p=0,004). Conclusões Observou-se diferença na prevalência de diabetes melittus gestacional entre os dois critérios analisados, sendo que o novo critério proposto aumentou a prevalência.

Prevalence of Sleep Bruxism and Association with Oral Health Conditions in Schoolchildren in a Municipality in Southern Brazil

Abstract Objective: To estimate the prevalence of sleep bruxism and its association with oral health conditions in schoolchildren. Material and Methods: Cross-sectional study carried out in public schools of Tubarão, SC, Brazil with students aged 10 to 15 years. The oral examination was performed in classrooms by dental surgeons, using the WHO criteria. Data on malocclusions, caries and dental trauma, fluorosis, bleeding gums and the presence of dental calculus were collected. For the diagnosis of bruxism, the criterion of the American Academy of Sleep Medicine was adopted. The chi-square test was used to assess the association between sleep bruxism and oral health conditions. Prevalence ratios and confidence intervals were estimated by Poisson regression with robust estimator. Results: A total of 389 students were examined. The prevalence of sleep bruxism was 22.0%. Schoolchildren with malocclusion, increased overjet and dental calculus showed a statistically higher and independent prevalence of 9.0% (p=0.003), 6.0% (p=0.006) and 19.0% (p<0.001), respectively. Conclusion: Prevalence of sleep bruxism was 22% in the study population and was associated with malocclusions, particularly increased overjet, and the presence of dental calculus.

Pode-se concluir que a tendência das internações por ATT no Estado de Santa Catarina foi crescente entre 2008 e 2016, em maiores proporções no sexo masculino e na faixa etária 20-39 anos.

Road traffic accidents (RTA) have a significant impact on society. Its consequences imply high numbers of hospital admissions, public health expenditures, and lost productivity. To analyze the temporal tendency of hospitalizations by RTA in Santa Catarina, between 2008 and 2016. This is an ecological time-trend study, with data of 61,412 thousand hospitalizations per RTA in a resident population in Santa Catarina, according to gender and age group. The records referring to hospitalizations for RTA according to year were analyzed, being this the independent variable (2008 to 2016) and the dependent variables were the general rate, the hospitalization rate according to sex and age group. For the time trend analysis through simple linear regression method, hospitalization rates were used. The general rate RTA increased by 91.01%, from 65.99 (2008) to 126.03 / 100,000 (2016). The increase was higher in males (94.25%), with a linear trend increasing, from 50.59 (2008) to 98.26 / 100.000 inhabitants (2016). Among women, the increase in the period was 80.44%. The highest incidence of hospitalizations occurred in the age group 20 to 39 years (89.54%), followed by the age range of 40 to 59 years, with 128.41%. It can be concluded that the tendency of hospitalizations for RTA in the State of Santa Catarina was increasing between 2008 and 2016, in greater proportions in males and in the age group 20-39 years.
