0202/2024 - Prevalência e fatores associados à obesidade abdominal em amostra nacionalmente representativa de idosos (ELSI-Brasil) Prevalence and factors associated with abdominal obesity in a nationally representative sample of older adults (ELSI-Brazil)
Objetivou-se avaliar a prevalência de obesidade abdominal (total e por sexo), características sociodemográficas e de saúde associadas e o potencial efeito modificador do sexo em idosos brasileiros. Foram utilizados dados transversais de 5.466 participantes da 2ª onda do Estudo Longitudinal da Saúde dos Idosos Brasileiros (ELSI-Brasil, 2019-21). A obesidade abdominal foi definida pela circunferência da cintura (?88cm para mulheres e ?102cm para homens). As análises foram baseadas na regressão de Poisson com variância robusta e termos de interação. A prevalência de obesidade abdominal foi 55,1%, sendo mais alta entre as mulheres (71,5%) do que entre os homens. Após ajustamentos, as análises revelaram associação positiva entre obesidade abdominal e multimorbidade (RP 1,37; IC95% 1,27-1,47) e associações negativas entre obesidade abdominal e sexo masculino (RP 0,52; IC95% 0,48-0,57), idade ?80 anos (RP 0,86; IC95% 0,76-0,96), residência rural (RP 0,82; IC95% 0,71-0,96) e tabagismo (RP 0,78; IC95% 0,68-0,89). Foi observada interação entre área de residência e sexo (p-valor=0,002) e multimorbidade e sexo (p-valor=0,007). Os resultados reforçam a relevância de ações intersetoriais no enfrentamento da obesidade abdominal, com abordagens integradas que considerem a prevenção e o controle de condições crônicas em homens e mulheres.
The objectives were to evaluate the prevalence of abdominal obesity (total and by sex), associated sociodemographic and health characteristics, and the potential modifying effect of sex in older Brazilian adults. Cross-sectional data5,466 participantsthe 2nd wave of the Brazilian Longitudinal Study of Aging (ELSI-Brazil, 2019-21) were used. Abdominal obesity was defined by waist circumference (≥88cm for women and ≥102cm for men). Analyses were based on Poisson regression with robust variance and interaction terms. The prevalence of abdominal obesity was 55.1%, being higher among women (71.5%) than among men. After adjustments, the analyses revealed a positive association between abdominal obesity and multimorbidity (PR 1.37; 95%CI 1.27-1.47), and negative associations between abdominal obesity and male sex (PR 0.52; 95%CI 0.48-0.57), age ≥80 years (PR 0.86; 95%CI 0.76-0.96), rural residence (PR 0.82; 95%CI 0.71-0.96), and smoking (PR 0.78; 95%CI 0.68-0.89). An interaction was observed between area of residence and sex (p-value=0.002) and multimorbidity and sex (p-value=0.007). The results reinforce the relevance of intersectoral actions in combating abdominal obesity, with integrated approaches that consider preventing and controlling chronic conditions in men and women.

Resumo (abstract):
The objectives were to evaluate the prevalence of abdominal obesity (total and by sex), associated sociodemographic and health characteristics, and the potential modifying effect of sex in older Brazilian adults. Cross-sectional data5,466 participantsthe 2nd wave of the Brazilian Longitudinal Study of Aging (ELSI-Brazil, 2019-21) were used. Abdominal obesity was defined by waist circumference (≥88cm for women and ≥102cm for men). Analyses were based on Poisson regression with robust variance and interaction terms. The prevalence of abdominal obesity was 55.1%, being higher among women (71.5%) than among men. After adjustments, the analyses revealed a positive association between abdominal obesity and multimorbidity (PR 1.37; 95%CI 1.27-1.47), and negative associations between abdominal obesity and male sex (PR 0.52; 95%CI 0.48-0.57), age ≥80 years (PR 0.86; 95%CI 0.76-0.96), rural residence (PR 0.82; 95%CI 0.71-0.96), and smoking (PR 0.78; 95%CI 0.68-0.89). An interaction was observed between area of residence and sex (p-value=0.002) and multimorbidity and sex (p-value=0.007). The results reinforce the relevance of intersectoral actions in combating abdominal obesity, with integrated approaches that consider preventing and controlling chronic conditions in men and women.
