Resumo O objetivo deste artigo é identificar a prevalência e os fatores associados à obesidade abdominal dinapênica (OAD) em idosos de uma cidade da região Norte do Brasil. Estudo transversal realizado com 382 idosos comunitários residentes em Macapá, Amapá, Brasil. As informações socioeconômicas, clínicas e de saúde foram coletadas por meio de um formulário estruturado. A OAD foi definida pela combinação de dinapenia (força de preensão manual < 26 kgf para homens e < 16 kgf para mulheres) e obesidade abdominal (circunferência abdominal > 102 cm para homens e > 88 cm para mulheres). As análises descritivas e inferenciais foram realizadas utilizando os testes qui-quadrado, t de Student e regressão de Poisson. A prevalência de OAD foi de 10,73%. Na análise bivariada preliminar, as variáveis faixa etária, estado conjugal, número de doenças, incapacidade funcional para atividades básicas e instrumentais de vida diária, velocidade da marcha e nível de atividade física atenderam ao critério estabelecido. O modelo final indicou que apenas a velocidade da marcha foi um preditor para a OAD em idosos. A OAD afeta quase 11% dos idosos residentes nessa comunidade do Norte do Brasil; e a velocidade de marcha é um preditor que pode ser uma ferramenta útil para gerenciar e monitorar a saúde desta população.

Abstract This article aims to identify the prevalence of and factors associated with dynapenic abdominal obesity (DAO) in older adults in a city in the northern region of Brazil. A cross-sectional study was conducted with 382 community-dwelling older adults in Macapa, Amapa, Brazil. Socioeconomic, clinical, and health information were collected using a structured form. DAO was defined as a combination of dynapenia (handgrip strength of < 26 kgf for men and < 16 kgf for women) and abdominal obesity (abdominal circumference > 102 cm for men and > 88 cm for women). Descriptive and inferential analyses were performed using chi-squared tests, Student’s t-tests, and a Poisson regression. The prevalence of DAO was 10.73%. In the preliminary bivariate analysis, the variables of age range, marital status, number of diseases, functional disability for basic and instrumental activities of daily living, gait speed, and level of physical activity met the established criterion. The final model indicated that only gait speed was a predictor of DAO in older adults. DAO affects nearly 11% of community-dwelling older adults from northern Brazil; gait speed was a predictor of DAO and could be a useful tool for managing and monitoring this population’s health.

Abstract INTRODUCTION: Psychosocial aspects need to be discussed in the context of the Covid-19 pandemic. Currently, no studies have investigated the factors associated with social isolation and loneliness among community-dwelling older adults. Therefore, this study analyzed the association of social isolation and loneliness with socioeconomic, clinical, and health characteristics, and Covid-19-related variables, among community-dwelling older adults during the pandemic. METHODS: A cross-sectional study was conducted via a telephone survey of community-dwelling older adults aged ≥60 years in Macapa, Amapa, Brazil. A structured form was used to collect data. Descriptive and inferential analyses were performed using Pearson's correlation test and a linear regression model. RESULTS: Participants comprised 86 community-dwelling older adults with a mean age of 71.78+6.98 years. Among them, 9.3% were diagnosed with Covid-19, of whom 3.5% were hospitalized. Most participants reported no difficulty obtaining food, medicines, or attending routine medical appointments during the pandemic. Furthermore, 23.3% (n=20) were socially isolated, and 20.9% (n=18) reported feelings of loneliness. The mean values for fear, anxiety, and obsession were 19.01±7.25, 1.01±1.90, and 2.84±3.28, respectively. A moderate positive correlation was identified between loneliness and the number of diseases, and a weak positive correlation between loneliness and the number of medications and depressive symptoms and risk for sarcopenia. The linear regression model indicated that higher loneliness scores were associated with a greater number of diseases (β=0.288; p=0.007). CONCLUSIONS: The findings suggest a probable resilience of the older population to Covid-19, despite the association of loneliness with many diseases in times of a pandemic.
