目的利用全国居民营养调查数据,了解湖北省城乡居民铬营养摄入的现状。根据各类食物的摄入量和各类食物铬含量数据,评价人群膳食铬的营养水平。方法按中国居民营养与健康状况调查的方案调查取样,并按营养调查中各类食物的摄入量与实测食物中的铬含量相乘得到食物中铬营养的实际摄入量。并按城市和农村、不同性别、不同经济收入、不同文化程度、不同地区、不同年龄、以及糖耐量指标分级,分别评价不同人群的铬营养状况。结果湖北省城乡居民的每日人均铬摄入量为53.17μg,城市为48.70μg,农村为55.47μg。结论湖北省居民可能存在铬摄入偏低或不足。
Objective To understand the status quo of chromium nutrition intake of urban and rural residents in Hubei Province by using the national resident nutrition survey data. According to various types of food intake and various types of food chromium content data to assess the nutritional status of dietary chromium. Methods Sampling was conducted according to the program of nutrition and health status survey of Chinese residents. The actual intake of chromium nutrition in food was obtained by multiplying the intake of various foods in the nutrition survey and the chromium content in the measured foods. The status of chromium nutrition in different populations was evaluated separately according to urban and rural areas, different genders, different economic incomes, different educational levels, different regions, different ages and glucose tolerance indexes. Results The per capita chromium intake of urban and rural residents in Hubei Province was 53.17μg, in urban areas was 48.70μg, in rural areas was 55.47μg. Conclusions Hubei residents may have low or insufficient chromium intake.
