ABSTRACT
The aim of this study was to evaluate the effect of birth cohort on nutritional status among older elderly (71-81 years old) from the Bambuí Cohort Study of Aging, conducted in Brazil in 1997 and 2008. We compared the two birth cohorts - 1916-1926 (older cohort) and 1927-1937 (recent cohort) - considering body mass index (BMI = weight/height²), waist circumference (WC) and prevalence of overweight (BMI ³ 27kg/m²). BMI (β = 0.09, 95 percentCI 0.04, 0.15) and prevalence of overweight (PR = 1.02; 95 percentCI 1.01; 1.03) were higher in the recent cohort than the earlier cohort, regardless of sex and schooling. No difference was observed in WC. Stratified by sex, similar overall trends were observed for men, and WC was higher in the recent cohort. Among women there was no difference in BMI and overweight, but WC was lower in the recent cohort. The cohort effect was greater among older men and, in the near future, may result in greater prevalence of overweight in this group.
RESUMO
Este estudo avaliou o efeito de coorte de nascimento no estado nutricional de idosos de 71 a 81 anos, participantes em 1997 e 2008 da coorte de Bambuí, Minas Gerais, Brasil. Foram comparados idosos nascidos em 1916-1926 (coorte antiga) e em 1927-1937 (coorte recente), quanto ao índice de massa corporal (IMC = peso/altura²), circunferência da cintura (CC) e proporção de sobrepeso (IMC ³ 27kg/m²), utilizando-se modelos de regressão linear e de Poisson. Após ajustamento por sexo e anos de escolaridade, idosos da coorte recente em comparação à coorte antiga apresentaram maior IMC (β = 0,09; IC95 por cento 0,04; 0,15) e maior proporção de sobrepeso (RP = 1,02; IC95 por cento 1,01; 1,03), não se observando diferenças na CC. Entre os homens da coorte recente, foram observados aumentos do IMC, do sobrepeso e da CC. Entre as mulheres, constatou-se redução da CC. Os resultados mostram um efeito de coorte na piora das medidas antropométricas entre os homens, mas não entre as mulheres.
