评估钙摄入量对于骨质疏松症的流行病学研究是必要的。本研究旨在开发有效的食物频率问卷(FFQ)来估计日本人的膳食钙摄入量。FFQ包含26个项目，代表常见的钙来源。受访者为74名年龄在15岁至79岁之间的福井市女性，她们的膳食钙摄入量估计为638 306(S.D.)MG基于1996年全国营养调查期间保存的一天加权食物记录，被要求说明他们的消费频率和每种食物的通常份量(大、中、小)。训练有素的营养师采访了受试者，以确认他们对FFQ的回答。根据FFQ的平均每天钙摄入量(655+/-222毫克)与根据一天食物记录的钙摄入量没有显著差异。这些方法之间的相关系数为0.512，具有统计学意义。乳制品的钙摄入量具有良好的相关性，r=0.717。间隔3天填写的两份FFQ估计值之间的相关系数为0.900，具有较好的重测信度。因此，FFQ在流行病学研究中估算膳食钙摄入量是有效和可靠的。
Assessing calcium intake is necessary for epidemiological studies on osteoporosis. This study was aimed at developing a valid food frequency questionnaire (FFQ) to estimate the dietary calcium intake of Japanese people. The FFQ contains 26 items, representing common sources of calcium. The respondents, 74 women aged 15 - 79 years living in Fukui city, whose dietary calcium intake was estimated at 638 306 (S.D.) mg based on a one-day weighted food record kept during the National Nutrition Survey of 1996, were asked to indicate their consumption frequency and usual portion size (large, medium, small) for each food item. Trained dieticians interviewed the subjects to confirm their answers to the FFQs. The mean calcium intake per day according to the FFQ (655 +/- 222 mg) did not differ significantly from that according to the one-day food record. The coefficient of correlation between these methods was 0.512, a statistically significant value. The calcium intake from dairy products showed a good correlation, r = 0.717. The coefficient of correlation between the values estimated based on two FFQ filled out three days apart was 0.900, showing good test-retest reliability. Therefore, this FFQ is valid and reliable in estimating dietary calcium intake for epidemiological studies.
