0151/2021 - Incidência de aumento e redução do Índice de Massa Corporal na meia-idade: seguimento de quatro anos Incidence of increase and decrease in Body Mass Index in middle-aged men and women: four-year follow-up
Objetivou-se analisar a incidência de aumento e de redução do Índice de Massa Corporal (IMC) entre homens e mulheres de meia-idade segundo características sociodemográficas e classificação do estado nutricional. Trata-se de uma coorte de base populacional com 689 adultos com idade entre 40 e 64 anos seguidos por quatro anos. Verificou-se a proporção de redução e de aumento do IMC (? 1 kg/m²) segundo variáveis sociodemográficas e classificação do estado nutricional no baseline mediante regressão de Poisson bruta e ajustada. A maior incidência de redução do IMC foi observada entre os homens na faixa etária de 55 a 64 anos (RR:1,78; IC95%:1,06-3,00), naqueles sem companheira (RR:1,85; IC95%:1,09-3,14), nos classificados com sobrepeso (RR:2,06; IC95%:1,13-3,74) e obesidade (RR:2,33; IC95%:1,24-4,35), e entre as mulheres na faixa etária de 55 a 64 anos (RR:1,43; IC95%:1,02-2,00) e nas classificadas com obesidade (RR:2,10; IC95%:1,30-3,38). A incidência de aumento do IMC foi menor na faixa etária de 55 a 64 anos entre os homens (RR:0,62; IC95%:0,41-0,95) e mulheres (RR:0,68; IC95%:0,49-0,95). Estes dados são importantes para compreensão dos fatores relacionados à variação do IMC e elaboração de políticas públicas que visem o cuidado à saúde na meia-idade.

Abstract:
The aim was to analyze the incidence of increase and decrease in the Body Mass Index (BMI) among middle-aged men and women according to sociodemographic characteristics and classification of nutritional status. It is a population-based cohort of 689 adults aged 40 to 64 years followed up for four years. The proportion of reduction and increase in BMI (≥ 1 kg/m²) was verified according to sociodemographic variables and classification of nutritional status in the baseline by means of crude and adjusted Poisson regression. A higher incidence of reduced BMI there was among men in the 55-64 age group (RR:1.78; 95%CI:1.06-3.00), in those without a partner (RR:1.85; 95%CI:1.09-3.14), in those classified as overweight (RR:2.06; 95%CI:1.13-3.74) and obesity (RR:2.33; 95%CI:1.24-4.35), and among women in the 55-64 age group (RR:1.43; 95%CI:1.02-2.00) and in those classified as obese (RR:2.10; 95%CI%:1.30-3.38). The incidence of increased BMI was lower in the 55 to 64 age group among men (RR:0.62; 95%CI:0.41-0.95) and women (RR:0.68; 95%CI:0.49-0.95). These data are important for understanding the factors related to the variation of BMI and the elaboration of public policies aimed at the health care of middle-aged adults.
