使用多个24小时召回(24HR)，我们测试了七天饮食召回(7DDR)，开发的目的是评估饮食干预和其他临床试验中的营养暴露，特别是血脂，这些试验需要在中等时间段内测量效果。在三项研究中，共有261人在3到5周的时间段结束时完成了7DDR，在此期间，随机选择的日期电话管理3到7 24HR。其中一项研究的ANSI数据来自另一项研究(总n=678)，这使得我们能够测试7DDR在干预环境中预测血脂变化的能力。在相关和线性回归分析中，7DDR和24HR之间获得了高度的一致性。总能量：r=0.67，b=0.69；总脂肪摄入量(g/d)：r=0.67，b=0.80。当有7天的24小时可用时，一致性趋于较高。总能量：r=0.69，b=0.95；总脂肪(g/天)：r=0.71，b=1.04。从7DDR得到的数据并符合Keys和Hegsted方程，可以很好地预测血清总胆固醇的实际变化(分别在15%和10%以内)。7DDR是一种相对容易管理、敏感的方法，可以评估个人饮食脂肪摄入量的短期变化。(C)1997年爱思唯尔科学公司。
Using multiple 24-hr recalls (24HR) we tested the Seven Day Dietary Recall (7DDR) developed to assess nutrient exposures, especially lipids, in dietary interventions and other clinical trials requiring measurement of effect over moderate time periods. A total of 261 individuals in three studies completed a 7DDR at the end of a 3- to 5-week period during which 3 to 7 24HR were telephone-administered on randomly selected days. One of these studies ansi data from one additional study (total n = 678) allowed us to test the ability of the 7DDR to predict serum lipid changes in an intervention setting.In correlation and linear regression analyses, high levels of agreement between 7DDR and 24HR were obtained. For total energy: r = 0.67 and b = 0.69, and for total fat intake (g/day): r = 0.67 and b = 0.80. When 7 days of 24HR were available agreement tended to be higher. For total energy: r = 0.69 and b = 0.95, and for total fat (g/day): r = 0.71 and b = 1.04. Data derived from the 7DDR and fit to the Keys and Hegsted equations closely predicted actual changes in total serum cholesterol (within 15% and 10%, respectively). The 7DDR is a relatively easily administered, sensitive method to assess short-term changes in dietary fat consumption in individuals. (C) 1997 Elsevier Science Inc.
