Resumo O objetivo deste estudo foi descrever a prevalência de idosos com uma ingestão adequada de água e seus fatores associados. Estudo transversal de base populacional realizado em 2014 com idosos (≥ 60 anos) participantes do estudo “COMO VAI?”. Investigou-se o número de copos de água ingeridos/dia pelos entrevistados, considerando-se adequada a ingestão de pelo menos oito copos/dia. As variáveis independentes foram características sociodemográficas, comportamentais e de saúde. A regressão de Poisson foi utilizada para a investigação das associações. Foram entrevistados 1.451 idosos, sendo observado que uma baixa percentagem, 12,6% (IC95% 10,8; 14,7) referiu consumo adequado de água. Maior percentagem de consumo adequado de água foi observada nos idosos mais jovens, com excesso de peso, que apresentaram cinco ou mais doenças e que eram mais dependentes quanto à capacidade funcional. A tendência decrescente de ingestão de água em relação à idade torna essencial o desenvolvimento de ações voltadas para essa população de maior risco acerca da importância de uma ingestão hídrica adequada e das possíveis consequências do seu consumo inadequado.

Abstract The scope of this study was to determine the percentage of elderly individuals receiving an adequate water intake and associated factors among non-institutionalized elderly individuals in the urban area of Pelotas, Rio Grande do Sul. It involved a cross-sectional, population-based study carried out in 2014 with elderly participants (≥ 60 years) of the “COMO VAI?” survey. The amount of water ingested per day of the interviewees was investigated, considering the intake of at least eight glasses per day to be adequate. The independent variables were sociodemographic, behavioral, and health characteristics, and Poisson Regression was used to investigate associations. A total of 1,451 elderly people were interviewed, with only 12.6% (95%CI 10.8; 14.7) drinking a sufficient amount. A higher percentage of the elderly with adequate water consumption was observed in younger elderly individuals, those overweight, those with five or more diseases, and those who were more impaired. A low percentage of the elderly with an adequate water intake was observed among the elderly adults in the study. The decreasing trend of water intake in relation to age highlights the importance of developing actions for the higher risk population to stress adequate water intake and the possible consequences of the lack of adequate consumption.

RESUMO Objetivo: Este estudo visou avaliar a necessidade de ajuda dos idosos para tomar seus medicamentos, bem como as dificuldades relacionadas com a sua utilização, e a frequência de esquecimento de doses. Ainda, avaliar fatores associados à necessidade de ajuda dos idosos com os medicamentos. Métodos: Corte transversal em uma coorte de idosos (60 anos ou mais — estudo “COMO VAI?”), em que foi avaliada a necessidade de ajuda para tomar medicamentos de forma adequada e as dificuldades apresentadas na sua utilização. Utilizou-se regressão de Poisson para estimar as razões de prevalência (RP) brutas e ajustadas dos desfechos e seus intervalos de confiança de 95% (IC95%) de acordo com as características da amostra. Resultados: Participaram 1.161 idosos. A prevalência de idosos que relataram necessidade de ajuda com os medicamentos foi de 15,5% (IC95% 13,5–17,8), sendo que os mais idosos, com menor escolaridade e em pior situação econômica, em uso de quatro medicamentos ou mais e com pior autoavaliação de saúde foram os que mais necessitaram de ajuda. O uso contínuo de medicamentos foi referido por 83,0% (IC95% 80,7–85,1) e a maioria (74,9%; IC95% 72,0–77,5) nunca se esqueceu de tomar seus medicamentos. Conclusão: Observou-se a influência de determinantes sociais e econômicos e de saúde sobre a necessidade de ajuda para a utilização dos medicamentos. Estudos que estimem as dificuldades no uso de medicamentos por idosos são importantes para subsidiar políticas e práticas norteadoras de ações para melhorar a adesão e o uso racional de medicamentos.

ABSTRACT Objective: This study aimed to assess the need for help by elderly people to take their medications, the difficulties related to this activity, the frequency of forgotten doses, and factors associated. Methods: Cross-sectional study conducted with a cohort of elderly people (60 years and over — “COMO VAI?” [How do you do?] study), where the need for help to properly take medication and the difficulties faced in using them were evaluated. The Poisson regression model was used to estimate the crude and adjusted prevalence ratios (PR) of the outcomes and respective 95% confidence intervals according to the characteristics of the sample. Results: In total, 1,161 elderly people were followed up. The prevalence of participants who reported requiring help with medication was 15.5% (95%CI 13.5–17.8), and the oldest subjects, with lower educational levels, in worse economic situations, on four or more medications and in bad self-rated health were the ones who needed help the most. Continuous use of medication was reported by 83.0% (95%CI 80.7–85.1) of the sample and most participants (74.9%; 95%CI 72.0–77.5) never forgot to take their medications. Conclusion: The need for help to use medications was shown to be influenced by social and economic determinants. Studies assessing the difficulties in medication use by the elderly are important to support policies and practices to improve adherence to treatment and the rational use of medications.

RESUMO OBJETIVO Mensurar a prevalência de uso de serviços odontológicos no último ano e os fatores associados em adultos de 31 anos pertencentes à coorte de nascimentos de 1982. MÉTODOS Estudo transversal, aninhado na coorte de nascimentos de Pelotas de 1982. Em 1997, uma amostra sistemática de 27% dos setores censitários da cidade foi realizada e todos os domicílios desses setores foram visitados, onde 1.076 adolescentes de 15 anos foram entrevistados. Para os estudos de saúde bucal foram sorteados aleatoriamente 900 desses indivíduos, que foram acompanhados também aos 24 e 31 anos. O estudo utilizou dados coletados de 523 indivíduos em 2013 (aos 31 anos). O desfecho foi a ida ao dentista (uso do serviço) no último ano. Fatores demográficos, (sexo), socioeconômicos (renda, escolaridade) e de saúde bucal (motivo e tipo de serviço da consulta, autopercepção de saúde bucal, dor e experiência de cárie - CPOD) foram utilizados como variáveis independentes. As razões de prevalência foram estimadas usando a regressão de Poisson. RESULTADOS A prevalência de uso de serviços odontológicos no último ano foi de 55,3% (IC95%: 51,0 –59,5%). Na análise ajustada, o motivo e tipo de serviço da consulta, a autopercepção de saúde bucal e o CPOD foram associados ao desfecho. Foi encontrada maior associação com a utilização de serviços odontológicos em indivíduos que visitaram por prevenção e usaram o serviço privado, satisfeitos com a sua saúde bucal e que tinham maior experiência de cárie. CONCLUSÃO 55,3% da amostra da coorte utilizaram os seviços odontológicos no último ano. Os indivíduos que visitaram o dentista por motivo preventivo, em consulta privada, que estavam muito satisfeitos ou satisfeitos com sua saúde bucal utilizaram em maior proporção esses serviços. Além disso, o maior índice de CPOD também levou ao maior uso.

ABSTRACT OBJECTIVE Measure the prevalence of use of dental services in the previous year and associated factors among 31-year-old adults from a birth cohort of 1982. METHODS This is a cross-sectional study that analyzed a birth cohort of 1982 from the city of Pelotas. In 1997, a systematic sample of 27% of the city’s census sectors was defined and all households in these sectors were visited, where 1,076 15-year-old adolescents were interviewed. For the oral health studies, 900 of these individuals were randomly selected and followed up at 24 and 31 years of age. The study used data collected from 523 individuals in 2013 (at 31 years old). The outcome was visit to the dentist (use of dental services) in the previous year. Demographic factors (sex), socioeconomic factors (income, education), and oral health factors (reason and type of service, self-perception of oral health, dental pain and caries experience - DMFT) were used as independent variables. Prevalence ratios were estimated using Poisson regression. RESULTS The prevalence of use of dental services in the previous year was 55.3% (95%CI: 51.0–59.5%). In the adjusted analysis, the reason and type of service, self-perception of oral health, and DMFT were associated with the outcome. A stronger association was found with use of dental services in individuals who visited for prevention and used the private service, who were satisfied with their oral health, and who had more caries experiences. CONCLUSION 55.3% of the cohort sample used dental services in the previous year. Individuals who visited the dentist of private service for preventive reasons, who were very satisfied with their oral health, used these services in a higher proportion. In addition, a higher DMFT index also led to higher use of services.

Abstract This study aimed to assess the mental health of a University community in South Brazil during the COVID-19 pandemic. A cross-sectional web-based survey was conducted between July-August 2020 through a self-administered questionnaire. All University staff and students were eligible. Depression was measured using the Patient Health Questionnaire-9 and anxiety by the Generalized Anxiety Disorder-7. To evaluate the effect of social distancing and mental health factors on outcomes, Poisson regression models with robust variance were performed, estimating Prevalence Ratios (PR) and 95% Confidence Intervals (95%CI). 2,785 individuals participated in the study. Prevalence of depression and anxiety were 39.2% (95%CI 37.3-41.1) and 52.5% (95% CI 50.6-54.4), respectively. Undergraduate students showed a higher prevalence of the outcomes. Not leaving the house routinely, mental health care, and previous diagnosis of mental illness were associated with both outcomes. Those with a previous medical diagnosis of depression had a 58% (PR 1.58; 95%CI 1.44; 1.74) and anxiety a 72% (PR 1.72; 95%CI 1.56; 1.91) greater prevalence of depression than their peers. An alarming prevalence of psychopathologies was observed. Despite the well-known benefits of social distancing to public health, it requires a surveillance on the population’s mental health, especially students and those with previous mental illness diagnosis.

Abstract This longitudinal study aimed to investigate the association between self-perceived oral health, oral-health-related quality-of-life (OHRQoL), toothache, and university students’ academic performance or dropout. A cohort of 2,089 students from 64 different courses at a public university in southern Brazil was interviewed in 2016 regarding their self-perceived oral health (Locker instrument; dichotomized into good/poor), OHRQoL (Oral Impacts on Daily Performances instrument, OIDP) and having had any toothache over the last 6 months (yes/no). After three years (2020), the academic records of 1,870 of these students were assessed, their average grade over all courses evaluated, and their dropout status was determined. Multivariable linear or logistic regression adjusting for gender, skin color, age, family income and maternal education was used to associate oral health variables (self-perceived oral health, OIDP, toothache) and academic performance or dropout. In 2016, 28.6% reported negative self-perceived oral health through the Locker instrument and 31.4% had toothache in the last 6 months. Over the next three years, 36.2% had dropped out. In multivariable regression, toothache in the last 6 months had a decrease of 0.32 (β -0.32, CI95% -0.59; -0.04) points in the final grade and were 35% (OR 1.35 CI95% 1.08; 1.69) more likely to dropout than students without toothache. In conclusion, this study showed that worse oral health conditions may be associated with worse academic performance or dropping out.

Abstract Although periodontal disease is common during pregnancy, little is known about socioeconomic, behavioral, or biological determinants related to clinically assessed periodontal condition during this period. We assessed the prevalence of periodontal disease and associated factors in pregnant women. This population-based survey used data used from the 2015 Pelotas Birth Cohort Study, Brazil. Pregnant women expected to give birth between December 2014 and May 2016 were interviewed and clinically examined by trained dentist, with periodontal measures collected in all teeth, six sites per tooth. Outcomes were periodontitis (using the 2012 Centers for Disease Control and Prevention and the American Academy of Periodontology criteria) and gingivitis (by the 2018 European Federation of Periodontology/ American Academy of Periodontology classification). Multivariate hierarchical Poisson regression was used to assess the associations between socioeconomic, systemic, and clinical oral factors and periodontal disease. A total of 2,474 pregnant women participated in the study. Prevalence of periodontitis and gingivitis was 14.63% and 21.67%, respectively. Lower educational level and calculus were associated with higher prevalence periodontitis and gingivitis (P<0.05). Smoking was also associated with periodontitis (P=0.05), and lower frequency of toothbrushing (P=0.005) with gingivitis. Periodontal disease, especially gingivitis, was prevalent in pregnant women and their determinants were socioeconomic, environmental, and clinical oral health factors.

This cross-sectional survey investigated the pandemic impact on dental practice in May 2021 (second wave in Brazil). COVID-19 incidence and severity among respondents, vaccination status, and level of confidence in vaccines were surveyed, in addition to medications used for preventing or treating COVID-19, including controversial drugs/substances (vitamin D, ivermectin, zinc, and chloroquine). Dentists were recruited by email and responded to a pretested questionnaire until May 31, 2021. In total, 1,907 responses were received (21.2% return rate). Bivariate and multivariate regression analyses were performed (α=0.05). Prevalence Ratios were calculated for the association between professional characteristics and two outcomes: report of SARS-CoV-2 infection and use of controversial drugs. One third of dentists reported intermediate levels of confidence in safety/efficacy of vaccines, but 96% received at least one vaccine dose, mainly CoronaVac. The impact of the pandemic on dental practice was rated as lower/much lower compared with one-year before (first wave) by 46% of respondents; 27% of dentists reported to have had a positive COVID-19 test, ~50% had relatives or friends who had been hospitalized or died from COVID-19. At least one medication was used by 59% of respondents, 43% used two or more drugs and substances. Vitamin D (41%), (35%), and zinc (29%) were the most frequent drugs/substances. More experienced dentists (≥21 years in practice) were 42% more likely to use controversial medications than less experienced respondents. Dentists with residency/advanced training as postgraduate education had 30% higher prevalence of controversial medication use than respondents holding MSc/PhD degrees. Respondents with low confidence in vaccines were 2.1 times more likely to use controversial medications than participants with very high confidence. The overall findings of this survey highlight the high severity of the pandemic in Brazil, and raised questions about the use of scientific evidence by dentists in their decision to take controversial COVID-19 medications.

O estudo teve como objetivo estimar as desigualdades sociais e raciais na autoavaliação da saúde bucal em adultos de um estudo de coorte de nascimentos no Brasil. O estudo atual faz parte do estudo de coorte de nascimentos de 1982 de Pelotas, Rio Grande do Sul, Brasil. Os dados foram coletados sobre as condições de saúde bucal aos 31 anos (Estudo de Saúde Bucal). A variável de desfecho era a autoavaliação da saúde bucal, dicotomizada em positiva (boa/muito boa) vs. negativa (regular/ruim/muito ruim). As análises foram estratificadas por sexo, grupo étnico-racial, escolaridade e renda. Para a análise estatística, foram utilizados o índice de desigualdade absoluta (SII) e o índice de concentração (CIX). A prevalência de autoavaliação da saúde bucal negativa foi 36,1%. Foram observadas desigualdades na autoavaliação da saúde bucal, em termos tanto absolutos quanto relativos. Foram observados SII de -30,0 (IC95%: -43,6; -16,4) para renda e -27,7 (IC95%: -41,9; -13,4) para escolaridade. Renda individual e escolaridade tiveram CIX negativos (CIXrenda -14,6 [IC95%: -21,2; -8,0] e CIXescolaridade -14,1 [IC95%: -20,7; -7,5]). Além disso, a prevalência de autoavaliação da saúde bucal negativa em indivíduos pretos, pardos e indígenas nas faixas de renda e escolaridade mais altas era comparável à prevalência desse desfecho entre indivíduos brancos pertencentes ao menor nível de renda e escolaridade. Os resultados desse estudo revelam disparidades raciais na saúde bucal, independente de renda e escolaridade. Além disso, foi identificada maior concentração de autoavaliação da saúde bucal negativa entre indivíduos com maior vulnerabilidade socioeconômica. Os achados reforçam a presença de desigualdades raciais e socioeconômica na saúde bucal no Brasil.

This study aimed to estimate social and racial inequalities in self-rated oral health in adults from the Brazilian birth cohort study. This study belongs to 1982 Pelotas (Brazil) birth cohort study. Data from this study was collected for oral health conditions 31 years old (Oral Health Study). The outcome was self-rated oral health, dichotomized into positive (good/very good) and negative (regular/bad/very bad). Analyses were stratified by gender, racial/skin color groups, schooling level and income. For statistical analysis, the slope index of inequality (SII) and the concentration index (CIX) were used. The prevalence of negative self-rated oral health was 36.1%. Social inequalities were observed in self-rated oral health in both absolute and relative terms. A SII of -30.0 (95%CI: -43.6; -16.4) was observed for income, and -27.7 (95%CI: -41.9; -13.4) for schooling level. Both the individuals’ income and the schooling level had negative CIX (CIXincome -14.6 [95%CI: -21.2; -8.0] and CIXschooling level -14.1 [95%CI: -20.7; -7.5]). Furthermore, the prevalence of negative self-rated oral health in black/brown/indigenous individuals from the highest income/schooling level was comparable to prevalence of the outcome in the white individuals belonging to the lowest income/schooling levels. This study results demonstrate racial disparities in oral health regardless of income and schooling levels. Furthermore, a higher concentration of negative self-rated oral health was identified among the most socioeconomically vulnerable individuals. Our findings reinforce the presence of racial and socioeconomic inequalities in oral health.

El objetivo fue estimar las inequidades sociales y raciales en la salud oral autoinformada de adultos, mediante el estudio de una cohorte de nacimientos en Brasil. Este trabajo pertenece al estudio de la cohorte de nacimientos de 1982 en Pelotas (Rio Grande do Sul, Brasil). Los datos que se recogieron en este estudio estaban relacionados con las condiciones de salud oral durante 31 años (Estudio de Salud Oral). El resultado fue la salud oral autoinformada, dicotomizada en positiva (buena/muy buena) y negativa (regular/mala/muy mala). Los análisis se estratificaron por sexo, grupos raciales/étnicos, nivel educacional e ingresos. Para el análisis estadístico se usaron el índice de inequidad absoluto (SII) y el índice de concentración (CIX). La prevalencia de salud oral autoinformada negativa fue 36,1%. Se observaron inequidades sociales en salud oral autoinformada tanto en términos absolutos como relativos. Se observó un SII de -30,0 (IC95%: -43,6; -16,4) en ingresos, y de -27,7 (IC95%: -41,9; -13,4) en la escolaridad alcanzada. Tanto los ingresos individuales, como la escolaridad alcanzada, tuvieron un CIX negativo (ingreso CIX -14,6 [IC95%: -21,2; -8,0] y un nivel CIXeducacional -14,1 [IC95%: -20,7; -7,5]). Asimismo, la prevalencia de una salud oral autoinformada negativa en individuos negros/mestizos/indígenas del nivel más alto de ingresos/educación fue comparable a la prevalencia del resultado en los individuos blancos que pertenecen a los niveles más bajos de ingresos/educacionales. Los resultados de este estudio demuestran disparidades raciales en la salud oral, independientemente de los ingresos y educación. Además, se identificó una concentración más alta de salud oral autoinformada negativa entre los individuos más vulnerables socioeconómicamente. Estos hallazgos refuerzan la presencia de inequidades raciales y socioeconómicas en la salud oral.

O estudo teve como objetivo estimar as desigualdades sociais e raciais na autoavaliação da saúde bucal em adultos de um estudo de coorte de nascimentos no Brasil. O estudo atual faz parte do estudo de coorte de nascimentos de 1982 de Pelotas, Rio Grande do Sul, Brasil. Os dados foram coletados sobre as condições de saúde bucal aos 31 anos (Estudo de Saúde Bucal). A variável de desfecho era a autoavaliação da saúde bucal, dicotomizada em positiva (boa/muito boa) vs. negativa (regular/ruim/muito ruim). As análises foram estratificadas por sexo, grupo étnico-racial, escolaridade e renda. Para a análise estatística, foram utilizados o índice de desigualdade absoluta (SII) e o índice de concentração (CIX). A prevalência de autoavaliação da saúde bucal negativa foi 36,1%. Foram observadas desigualdades na autoavaliação da saúde bucal, em termos tanto absolutos quanto relativos. Foram observados SII de -30,0 (IC95%: -43,6; -16,4) para renda e -27,7 (IC95%: -41,9; -13,4) para escolaridade. Renda individual e escolaridade tiveram CIX negativos (CIXrenda -14,6 [IC95%: -21,2; -8,0] e CIXescolaridade -14,1 [IC95%: -20,7; -7,5]). Além disso, a prevalência de autoavaliação da saúde bucal negativa em indivíduos pretos, pardos e indígenas nas faixas de renda e escolaridade mais altas era comparável à prevalência desse desfecho entre indivíduos brancos pertencentes ao menor nível de renda e escolaridade. Os resultados desse estudo revelam disparidades raciais na saúde bucal, independente de renda e escolaridade. Além disso, foi identificada maior concentração de autoavaliação da saúde bucal negativa entre indivíduos com maior vulnerabilidade socioeconômica. Os achados reforçam a presença de desigualdades raciais e socioeconômica na saúde bucal no Brasil.

This study aimed to estimate social and racial inequalities in self-rated oral health in adults from the Brazilian birth cohort study. This study belongs to 1982 Pelotas (Brazil) birth cohort study. Data from this study was collected for oral health conditions 31 years old (Oral Health Study). The outcome was self-rated oral health, dichotomized into positive (good/very good) and negative (regular/bad/very bad). Analyses were stratified by gender, racial/skin color groups, schooling level and income. For statistical analysis, the slope index of inequality (SII) and the concentration index (CIX) were used. The prevalence of negative self-rated oral health was 36.1%. Social inequalities were observed in self-rated oral health in both absolute and relative terms. A SII of -30.0 (95%CI: -43.6; -16.4) was observed for income, and -27.7 (95%CI: -41.9; -13.4) for schooling level. Both the individuals’ income and the schooling level had negative CIX (CIXincome -14.6 [95%CI: -21.2; -8.0] and CIXschooling level -14.1 [95%CI: -20.7; -7.5]). Furthermore, the prevalence of negative self-rated oral health in black/brown/indigenous individuals from the highest income/schooling level was comparable to prevalence of the outcome in the white individuals belonging to the lowest income/schooling levels. This study results demonstrate racial disparities in oral health regardless of income and schooling levels.

Abstract The purpose of this study was to investigate the association between maternal factors and dental visits of children within their first year of life. This study used data from the 2015 Pelotas Birth Cohort and included pregnant women and their children at 12 months of age, followed-up between May 2014 and December 2015. Socioeconomic and demographic data, information on the use of dental services during the last year, and information on dental fear were collected by interviewing the mothers. Information regarding dental caries and periodontal disease were collected during the mother’s clinical examination. The date of each child’s first visit to the dentist was recorded. Crude and adjusted Poisson regression models with robust variance were used. The sample comprised 2,287 mother-child dyads, of which 10.1% of children visited the dentist during the first year of life. Children whose mothers visited the dentist within the last year for preventive reasons (RR: 1.51; 95%CI: 1.12–2.03) or curative reasons (RR: 1.47; 95%CI: 1.08–2.01) were more likely to have visited the dentist during the first year of life compared to those whose mothers had not used dental services during this period. Maternal tooth loss was inversely associated with a child’s visit to the dentist during the first year of life (RR: 0.69; 95%CI: 0.54–0.89). Considering the mother’s history of using dental services, as well as their dental caries history, is necessary to understand and improve patterns of dental health care utilization and implement public oral health policies for young children.
