Prevalence of and risk factors for dynapenic abdominal obesity in community-dwelling older adults: a cross-sectional study

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.

Cross-Sectional Study on the Association Between Respiratory Muscle Strength and Dynapenic Abdominal Obesity in Community-Dwelling Older Adults

“…The present study comprises the same sample and the variable of interest, which is DAO, as in another previously published study. 41 However, the studies have different objectives, with different analyzes and results. For example, in the present study, the outcome of interest is respiratory muscle strength and we used some adjustment variables.…”

Association between sedentary behavior and dynapenic abdominal obesity among older adults from low- and middle-income countries

“…Dynapenic abdominal obesity (DAO) is defined as the co-existence of abdominal obesity and low muscle strength [ 1 ], and its prevalence has been reported to be high in the general population, particularly among older adults [ 2 ]. DAO is an emerging important risk concept as recent studies have shown that this condition is associated with a high risk for a myriad of adverse health outcomes including falls [ 3 , 4 ], cognitive impairment [ 5 ], worsening disability, and premature mortality [ 6 ].…”
