Brazil never had segregation laws defining membership of an ethnoracial group. Thus, the composition of the Brazilian population is mixed, and its ethnoracial classification is complex. Previous studies showed conflicting results on the correlation between genome ancestry and ethnoracial classification in Brazilians. We used 370,539 Single Nucleotide Polymorphisms to quantify this correlation in 5,851 community-dwelling individuals in the South (Pelotas), Southeast (Bambui) and Northeast (Salvador) Brazil. European ancestry was predominant in Pelotas and Bambui (median = 85.3% and 83.8%, respectively). African ancestry was highest in Salvador (median = 50.5%). The strength of the association between the phenotype and median proportion of African ancestry varied largely across populations, with pseudo R2 values of 0.50 in Pelotas, 0.22 in Bambui and 0.13 in Salvador. The continuous proportion of African genomic ancestry showed a significant S-shape positive association with self-reported Blacks in the three sites, and the reverse trend was found for self reported Whites, with most consistent classifications in the extremes of the high and low proportion of African ancestry. In self-classified Mixed individuals, the predicted probability of having African ancestry was bell-shaped. Our results support the view that ethnoracial self-classification is affected by both genome ancestry and non-biological factors.
OBJECTIVE To describe the prevalence and sociodemographic factors associated with informal and paid care for Brazilian older adults with functional limitations.METHODS Of the 23,815 participants of the National Health Survey aged 60 or older, 5,978 reported needing help to perform activities of daily living and were included in this analysis. The dependent variable was the source of care, categorized as exclusively informal (unpaid), exclusively formal (paid), mixed or none. The socio-demographic variables were age (60-64, 65-74, ≥ 75 years old), gender and number of residents in the household (1, 2, ≥ 3). The multivariate analysis was based on binomial and multinomial logistic regressions.RESULTS Informal care predominated (81.8%), followed by paid (5.8%) or mixed (6.8%) and no care (5.7%). The receipt of care from any source increased gradually with the number of residents in a same household, regardless of age and gender (OR = 4.85 and 9.74 for 2 and ≥ 3, respectively). Age was positively associated with receiving any care while the male gender showed a negative association. The number of residents in the household showed the strongest association with informal care (OR = 10.94 for ≥ 3 residents), compared with paid (OR = 5.48) and mixed (OR = 4.16) care.CONCLUSIONS Informal care is the main source of help for community-dwelling older adults with functional limitations. In a context of rapid population aging and decline in family size, the results reinforce the need for policies to support long-term care for older Brazilians.
Objective:To evaluate the clinical impact of a comprehensive medication management (CMM) service in a Brazilian primary health-care setting.Methods:A quasi-experimental study has been carried out between July 2014 and November 2016 with patients who received the service in the primary care setting of a Brazilian city (n = 1057). Factors associated with drug therapy problems (DTP) detection in the initial assessment were evaluated by performing univariate and multivariate analyzes. To evaluate the impact of the CMM service, a linear regression model was constructed from the difference between the initial and final values of the clinical and laboratory parameters adjusted by multiple variables.Results:A total of 1642 DTPs was identified, the most prevalent one being “nonadherence” (31.9%) and the “need for additional drug therapy” (22.9%). The use of 5 or more medications and the presence of 3 or more diseases were positively associated with the identification of 3 or more DTPs during the initial assessment. Even after multiple adjustments, a statistically significant reduction has been observed in the values of glycated hemoglobin, systolic blood pressure, low-density cholesterol, and total cholesterol.Conclusion:The CMM service contributed to the resolution of DTP and showed positive clinical impact in primary health care in the studied setting.
RESUMO: Objetivo: Apresentar os aspectos metodológicos do Projeto Saúde Brumadinho e descrever o perfil epidemiológico dos participantes da linha de base da coorte. Métodos: Coorte prospectiva, de base populacional, em amostra representativa dos residentes (12 anos ou mais de idade) de Brumadinho, Minas Gerais, após rompimento de barragem de rejeitos de mineração. As informações para a linha de base foram coletadas em 2021, dois anos após o rompimento da barragem de rejeitos de mineração, incluindo aspectos sociodemográficos, de saúde, uso de serviços, entre outros. Foram descritas prevalências de desfechos em saúde em Brumadinho, bem como na região metropolitana de Belo Horizonte e em Minas Gerais, utilizando os dados da Pesquisa Nacional de Saúde de 2019. Todas as análises foram realizadas no Stata 17.0, considerando-se os pesos amostrais e o efeito de delineamento. Resultados: Participaram 3.080 (86,4%) moradores, sendo a maioria do sexo feminino (56,7%) e com média de idade de 46,1 anos. As doenças referidas mais frequentes foram hipertensão arterial (30,1%), colesterol alto (23,1%) e depressão (22,5%). Pelo menos uma consulta médica e uma hospitalização no último ano ocorreram em 75,2% e 9,4% dos entrevistados, respectivamente. Conclusão: É importante o monitoramento das condições de saúde, físicas e mentais, após ocorrência de um desastre dessa magnitude. Esse conhecimento poderá contribuir para a gestão de risco desses processos não só no município atingido, mas em outras áreas nas quais as populações estão sob risco de grandes desastres.
OBJECTIVE To analyze the use of health services and the quality of medical care received by Brazilian older adults with and without functional limitation.METHODS The main analyses were based on a national sample representing 23,815 participants of the National Survey on Health (PNS) aged 60 years or older. Functional limitation was defined by the difficulty to perform at least one out of ten basic or instrumental activities of daily living. Potential confounding variables included predisposing and enabling factors of the use of health services.RESULTS The prevalence of functional limitation was 30.1% (95%CI 29.2–31.4). The number of doctor visits and hospitalizations in the past 12 months showed statistically significant associations with functional limitation, both for users of the public system (OR = 2.48 [95%CI 2.13–2.88] for three or more doctor visits and OR = 2.58 [95%CI 2.15–3.09] for one or more hospitalizations) and of the private system (OR = 2.56 [95%CI 1.50–4.36] and OR = 2.22 [95%CI 1.64–3.00], respectively). The propensity to use basic health units was higher among users of the private system with functional limitations (OR = 2.01 [95%CI 1.12–3.59]). Only two out of seven indicators of the quality of medical care received were associated with functional limitation, in the perception of users of public and private systems. The public system users with functional limitations did worse evaluation of the freedom for choosing the doctor and waiting time for an appointment, when compared with users of the same system without these limitations (OR = 0.81 [95%CI 0.67–0.99] and OR = 0.76 [95%CI 0.62–0.93], respectively).CONCLUSIONS Older adults with functional limitations use more health services in comparison with those without such limitations. The magnitude of the association between functional limitation and number of doctor visits and hospitalizations was similar in the public and private health systems.
The study revealed a high prevalence of PIM use among the community-based aged population. It also identified PIM use as a predictor for mortality in this group of individuals. This indicates the need for selection of safer drug therapy alternatives in this patient group.
OBJECTIVE To examine the factors associated with hospital use and their frequency in a nationally representative sample of the Brazilian population aged 50 years or older.METHODS Data from the baseline of the Brazilian Longitudinal Study of Aging (ELSI-Brazil), conducted in 2015-2016, were used. Predisposing, enabling and need factors for the use of health services were considered. The analyzes were based on the Hurdle regression model and on estimates of population attributable risks.RESULTS Among 9,389 participants, 10.2% had been hospitalized in the previous 12 months. After adjusting for potential confounding variables, statistically significant associations (p < 0.05) were observed for need factors (previous medical diagnosis for chronic diseases and limitation to perform basic activities of daily living) and for enabling factors (living in a rural area and in the North and Midwest regions of the country). The analysis of population attributable risks (PAR) showed a hierarchy of the need factors for the occurrence of hospitalizations, with higher contributions by stroke (PAR = 10.7%) and cardiovascular disease (PAR = 10.0%), followed by cancer (PAR = 8.9%), difficulty to perform basic activities of daily living (PAR = 6.8%), depression (PAR = 5.5%), diabetes (PAR = 4.4% ) and hypertension (PAR = 2.2%).CONCLUSIONS Four of the major diseases associated with hospitalizations (stroke, cardiovascular disease, diabetes and hypertension) are part of the Brazilian list of primary care-sensitive hospitalizations. These results show that there is a window of opportunity to reduce unnecessary hospitalizations among older Brazilian adults through effective primary care actions.
OBJECTIVETo describe the prevalence of the practice of physical activity (PA) among older Brazilian adults and associated factors. In addition, potential effect modifiers of the association between PA and age were investigated.METHODSWe have analyzed data from 8,736 participants (92.8%) aged 50 and older from the Brazilian Longitudinal Study of Aging (ELSI-Brazil). Physical activity was measured using the short version of the International Physical Activity Questionnaire. The outcome variable was defined as at least 150 minutes of weekly activities in all domains. The exploratory variables were age, sex, education, ethnicity, marital status, number of chronic diseases and medical appointments, and knowledge about or participation in public programs that encourage physical activity. Logistic regression and estimates of predicted probabilities were performed.RESULTSThe prevalence of recommended levels of physical activity was 67.0% (95%CI 64.3–69.5). Physical activity was associated with age [odds ratio (OR) = 0.97; 95%CI 0.96–0.98], higher educational level (OR = 1.27; 95%CI 1.11–1.45 for 4–7 years and OR = 1.52; 95%CI 1.28–1.81 for eight years or more), participants who were married/ in a long term relationship (OR = 1.22; 95%CI 1.08–1.38), and those who reported knowledge about (OR = 1.34; 95%CI 1.16–1.54) or participation in (OR = 1.78; 95%CI 1.34–2.36) a program aimed at the practice of physical activity. Women and those with lower educational level (p value for interaction < 0.05) reported lower physical activity levels.CONCLUSIONSIn addition to the association with marital status and health promotion programs, there were significant sex and educational level inequalities in physical activity decline later in life. These findings help the identification of groups more vulnerable to decreased physical activity levels with aging, as well as the planning of health promotion strategies, especially in older groups.
