Cross-sectional data from the 1991 (n = 1657) and 1993 (n = 1773) China Health and Nutrition Surveys were used to describe patterns in the diets, activity levels and body mass index (BMI) of elderly Chinese (aged 60 or older). In 1991 and 1993, the prevalence of low BMI (BMI < 18.5 or BMI < 22.0) exceeded 15%, while the prevalence of high BMI (BMI > 25.0 or BMI > 27.0) ranged between 4% and 24%. The BMI was consistently, positively and significantly associated with urban residence. Urban residence and income were consistently and positively associated with energy from fat and protein intakes, and decreasing physical activity levels. The results suggest that under- and overnutrition coexist among Chinese elders and are differentially distributed across income and urban/rural strata.
利用1991年（n = 1657）和1993年（n = 1773）中国健康与营养调查的横断面数据，描述中国老年人（60岁及以上）的饮食、活动水平和体重指数（BMI）模式。在1991年和1993年，低BMI（BMI < 18.5或BMI < 22.0）的患病率超过15%，而高BMI（BMI > 25.0或BMI > 27.0）的患病率在4%至24%之间。BMI始终与城市居住呈正相关且具有显著相关性。城市居住和收入始终与脂肪和蛋白质摄入的能量呈正相关，且与身体活动水平下降相关。结果表明，中国老年人中存在营养不足和营养过剩的情况，并且在收入和城乡阶层中分布存在差异。
