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P〈0.001）,除城区男性14-17岁组外,检测法结果明显低于查表法（均P〈0.05）;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。Objective To study dietary calcium intake in residents of Hangzhou municipality and to compare the re- suits derived from China Food Composition（CFC） and food sample measurement of total diet consumption. Methods Both food weighting and food recording were conducted among 1 744 community residents （7 -95 years old）selected with stratified cluster random sampling to collect information on total food consumption during 3 continuous days. Individual calcium intake was then calculated using both measurement results and data from CFC and compared with dietary reference intakes （ DRIs ） to analyze the correlation between the results derived from the two methods. Results The median of dally dietary calcium intake ranged from 385.9 - 610. 1 mg/d（ CFC derived） and 303.9 - 544. 2 mg/d （measurements derived）among the residents of different groups. All results derived from the measurements were lower than those of derived from CFC except for the urban male residents aged 14 - 17 years（P 〈0. 001 ） ,with the Spearman correlation coefficients of 0. 712 -0. 911 （P 〈 0. 05 ）. The proportions of the residents with adequate calcium intake （recommended nutrient intake, RNI） were 6. 9 % and 6. 1% （ CFC derived） for urban residents and 1.8 % and 0. 3 % （ CFC derived） for sub-urban residents, respectively. Conclusion Dietary calcium intake is prevailingly insufficient among the residents of Hangzhou municipality. The calcium intake estimation derived from measurements is lower than that of CFC, although there is a close correlation between the estimations derived from the two methods.
