在控制良好的喂养研究中，参与者应该坚持严格的饮食，只食用研究厨房提供的所有食物。他们可能会发现，在某些研究设计特征下，坚持使用更具挑战性。为了评估这一点，我们向在宾宁顿生物医学研究中心(巴吞鲁日)完成了八项受控喂养研究之一的参与者邮寄了一份研究后匿名问卷。在154名受访者中，超过90%的人总是或通常坚持节食。在那些没有坚持的人中，许多人偏离了不到四次。与不吃不允许的食物相比，吃所有提供的食物是更大的挑战。饮食分配、酒精摄入量和自己选择的周六餐都会影响患者的坚持。这项研究的结果可能对控制喂养研究的设计有帮助。我们的数据表明，坚持饮食是好的，因为偏离很少，它们不太可能危及研究结果。
yIn well-controlled feeding studies, participants are expected to adhere to a strict diet by consuming only and all foods provided by the research kitchen. They may find adherence more of a challenge with certain study design features. To assess this we mailed a poststudy anonymous questionnaire to participants who had completed one of eight controlled feeding studies at the Penning-ton Biomedical Research Center, Baton Rouge, IA. Of the 154 respondents, more than 90% always or usually adhered to the diet. Of those who did not adhere, many deviated fewer than four times. Eating all of the foods provided was a greater challenge than refraining from eating foods not allowed. Diet assignment, the allowance of alcohol, and a self-selected Saturday meal affected adherence. The results of this research may be useful in designing controlled feeding studies. Our data indicate that diet adherence is good, and because deviations are few, they are unlikely to jeopardize study results.
