There have been no simple methods to estimate dietary nutrient intakes for the prevention and management of osteoporosis. The aim of this study was to develop and validate a new, simple food frequency questionnaire (FFQ) for dietary intake of calcium and other nutrients relevant to the bone health of adult Japanese women. We developed a 28-item FFQ. To validate this, 208 and 72 adult women aged between 18 and 69 y were recruited for testing reliability and reproducibility, respectively. In the 208 women, moderate-to-high Spearman's correlation coefficients between our FFQ and the conventional diet record method were found in intakes of calcium (r=0.668), sodium chloride (NaCl) (r=0.475), vitamin A (r=0.501), vitamin D (r=0.413), vitamin K (r=0.649), and energy (r=0.471). In the 72 women, coefficients of variance of the four repeated measurements of intakes throughout a year were 14.1% for calcium, 7.3% for NaCl, 21.2% for vitamin A, 13.6% for vitamin D, 36.8% for vitamin K, and 9.6% for energy. In conclusion, the FFQ we developed is a useful tool to evaluate the intake of dietary calcium of adult Japanese women. Although it can also measure intakes of dietary vitamin A, vitamin D, vitamin K, NaCl, and energy, further improvement is needed to measure intakes of these nutrients and energy.
目前尚无简单方法可估算用于预防和管理骨质疏松症的膳食营养素摄入量。本研究旨在开发并验证一种新的、简单的食物频率问卷(FFQ),用于评估成年日本女性饮食中钙及其他与骨骼健康相关营养素的摄入量。我们开发了一份包含28个条目的FFQ。为验证其有效性,分别招募了208名和72名年龄在18至69岁之间的成年女性,用于测试可靠性和可重复性。在208名女性中,我们的FFQ与传统饮食记录法之间,在钙(r = 0.668)、氯化钠(NaCl)(r = 0.475)、维生素A(r = 0.501)、维生素D(r = 0.413)、维生素K(r = 0.649)和能量(r = 0.471)的摄入量方面,发现了中等至高的斯皮尔曼相关系数。在72名女性中,全年四次重复测量摄入量的方差系数分别为:钙14.1%、NaCl 7.3%、维生素A 21.2%、维生素D 13.6%、维生素K 36.8%、能量9.6%。总之,我们开发的FFQ是评估成年日本女性膳食钙摄入量的有用工具。尽管它也能测量膳食维生素A、维生素D、维生素K、NaCl和能量的摄入量,但在测量这些营养素和能量的摄入量方面仍需进一步改进。
