【摘要】：目的使用总膳食研究的食物样本检测结果和食物成分表食物营养素含量2种不同数据分析浙江省杭州市居民膳食钙摄入水平及分布。方法采用3 d食物称重法和3 d 24 h回顾法收集杭州市1 744名调查对象食物消费量数据,并对烹调后代表性食物样品钙含量进行检测,分别使用检测结果及食物成分表钙含量数据计算个体摄入量,并与膳食营养素参考摄入量(DRIs)比较,分析2种方法的相关性。结果杭州市不同性别与年龄组居民每日钙摄入量中位数为303.9~544.2 mg/d(检测法)和385.9~610.1 mg/d(查表法),两者rSpearman为0.712~0.911(均P0.001),除城区男性14~17岁组外,检测法结果明显低于查表法(均P0.05);城、郊居民摄入量达到推荐摄入量(RNI)者分别为6.9%、6.1%(查表法)和1.8%、0.3%(检测法)。结论杭州市居民膳食钙摄入量普遍明显不足,使用食物样品检测结果及食物成分表数据计算膳食钙摄入量具有较高的相关性,但前者明显低于后者。
[Abstract]:Objective to analyze the dietary calcium intake level and distribution of Hangzhou residents in Zhejiang province by using two different data of food samples and food composition table. Methods the food consumption data of 1 744 subjects in Hangzhou were collected by 3 d food weighing method and 3 d 24 h retrospective method, and the calcium content of typical food samples after cooking was detected. The individual intake was calculated by using the test results and the calcium content data of the food composition table, and the correlation between the two methods was analyzed compared with the dietary nutrient reference intake (DRIs). Results the median daily calcium intake of residents of different sex and age groups in Hangzhou was 303.9 mg/d (detection method) and 385.9 mg/d (610.1 mg/d), the rSpearman of both groups was 0.7120.911 (both P0.001). The results of the test were significantly lower than that of the look-up table method (P0.05), except for the 140-17 years old group of male in urban area. The intakes of (RNI) in urban and suburban residents were 6.9% and 0.3%, respectively. Conclusion the dietary calcium intake of Hangzhou residents was obviously insufficient. There was a high correlation between the results of food sample detection and the data of food composition table, but the former was significantly lower than the latter.
