摘要
目的与方法：我国正逐步进入老龄化社会，老年人（包括处于老年前期的个体）是出现各种营养问题的高危人群。作者利用１９９２年第三次全国营养调查资料，分析了我国４５岁以上中老年人的营养状况。结果：男性中营养不良者占１０．０６％，女性为１１．５５％，女性稍高于男性。但女性中肥胖者所占比例明显高于男性，分别为２５．４０％和１７．２４％。比较４５～岁组和６０～岁组中老年人中营养不良的现患率，６０～岁组是４５～岁组的两倍，７０～岁组又差不多是６０～岁组的两倍。城乡比较，城市中营养不良的现患率男女仅分别为５．６１％和５．４６％，而农村的中老年人中分别有１２．６５％的男性和１５．３１％的女性存在营养不良。城市中老年人中突出的营养问题是肥胖，男、女现患率分别达３１．７２％和４０．７９％，而农村仅分别为８．９８％和１５．９４％。各主要民族的中老年人中营养不良的现患率男女性都以壮族最高，分别达２１．３９％和３２．２９％，肥胖的现患率男女均以回族最高，分别达２１．５４％和４０．１５％。结论：分析营养素摄入与ＢＭＩ的关系，对于绝大多数中老年人来说，膳食质量低下已不是他们主要的营养问题，而过量摄入热能和蛋白质显然与肥胖现患率较高有关。此外?
Abstract Objective:To provide an understanding of the patterns of BMI in Chinese elderly population and the major influential factors.Data sources:1992 China National Nutrition Survey. More than 100 000 individuals of all ages were sampled nationwide，of which 17 716 were 45 years and above.Results:The prevalence of malnutrition of male and female elderly were 10.06％ and 11.55％ respectively. The prevalence of obesity in females was higher than that in males， they were 25.40％ and 17.24％ respectively. The prevalence of malnutrition of the elderly between 60－89 years of age was nearly twice that of younger elderly. In contrast， relatively few obese were observed among the age of 45－59 than in the age of 60－89.Malnutrition was less prevalent in urban than in rural areas. Obesity was more common among urban elderly， the prevalence rates reached 31.72％ and 40.79％ in male and female respectively. The corresponding prevalence in rural were only 8.98％ and 15.94％ respectively. It suggested that poor diet seemed not be the principal cause of malnutrition in Chinese elderly and overeating was obviously associated with obesity. Key words: nutrition survey BMI nutritional status elderly obesity
