title: [Effect of dietary intake on body mass index in middle aged and elderly population].
abstract: The paper investigated and analyzed the relationship between the nutrient intake and body mass index (BMI) of 200 middle-aged and elderly people(aged 35 - 74 years) in Changsha. The result showed that the constituent rate of underweight (BMI< 18.5) was 6.5% and that of over-weight (BMI<25.0) was 23.5%. The amount of fat intake constituted slightly higher proportion in energy intake. The stepwise regression analysis indicates that the body mass index increases with the increasing intake of carbohydrates.
