心理社会和饮食行为因素在多大程度上影响饮食自我报告仍不清楚。我们研究了这些因素对自我报告测量误差的贡献。在450名绝经后妇女的妇女健康倡议观察性研究中，双标记水和尿氮被用作总能量消耗和蛋白质的客观测量的生物标志物。自我报告从食物频率问卷（FFQ），四天食物记录（4DFR）和24小时饮食回忆（24 HR）中获取。使用回归校准，我们估计了自我报告的饮食工具，包括来自Stunkard-Sorenson身体轮廓的身体形象感知，Crowne-Marlowe社会期望量表和三因素饮食问卷（R-18）的心理社会因素的偏差认知抑制饮食，不受控制的饮食和情绪化饮食。我们使用4DFR纳入了关于在家吃饭次数的饮食行为因素。为六个心理社会和饮食行为变量中的每一个定义了三个类别（低，中，高）。与社会期望值低的参与者相比，社会期望值高的参与者更有可能在能量（β =-0.174，SE = 0.054，p < 0.05）和蛋白质摄入（β =-0.142，SE = 0.062，p < 0.05）的FFQ上报告不足。与在家用餐比例低的参与者相比，在家用餐比例高的参与者不太可能在能量（β = 0.181，SE = 0.053，p < 0.05）和蛋白质（β = 0.127，SE = 0.06，p < 0.05）的FFQ上报告不足。在将FFQ、4DFR、24 HR与年龄、体重指数、种族以及心理社会和饮食行为变量相结合的校准方程中，六个心理社会和饮食变量分别解释了能量、蛋白质和蛋白质密度的生物标志物变异的1.98%、2.24%和2.15%。在有或没有六个心理和饮食变量的校准方程之间，蛋白质密度（p = 0.02）的变化解释是显着不同的，但能量（p = 0.119）或蛋白质摄入量（p = 0.077）。将心理社会和饮食行为因素添加到校准方程中显著增加了蛋白质密度解释的总方差的量，并且预计将其包括在内将加强校准方程的精度，校正自我报告的测量误差。ClinicalTrials.gov标识符：NCT 00000611
The extent to which psychosocial and diet behavior factors affect dietary self-report remains unclear. We examine the contribution of these factors to measurement error of self-report. In 450 postmenopausal women in the Women’s Health Initiative Observational Study doubly labeled water and urinary nitrogen were used as biomarkers of objective measures of total energy expenditure and protein. Self-report was captured from food frequency questionnaire (FFQ), four day food record (4DFR) and 24 hr. dietary recall (24HR). Using regression calibration we estimated bias of self-reported dietary instruments including psychosocial factors from the Stunkard-Sorenson Body Silhouettes for body image perception, the Crowne-Marlowe Social Desirability Scale, and the Three Factor Eating Questionnaire (R-18) for cognitive restraint for eating, uncontrolled eating, and emotional eating. We included a diet behavior factor on number of meals eaten at home using the 4DFR. Three categories were defined for each of the six psychosocial and diet behavior variables (low, medium, high). Participants with high social desirability scores were more likely to under-report on the FFQ for energy (β = -0.174, SE = 0.054, p < 0.05) and protein intake (β = -0.142, SE = 0.062, p < 0.05) compared to participants with low social desirability scores. Participants consuming a high percentage of meals at home were less likely to under-report on the FFQ for energy (β = 0.181, SE = 0.053, p < 0.05) and protein (β = 0.127, SE = 0.06, p < 0.05) compared to participants consuming a low percentage of meals at home. In the calibration equations combining FFQ, 4DFR, 24HR with age, body mass index, race, and the psychosocial and diet behavior variables, the six psychosocial and diet variables explained 1.98%, 2.24%, and 2.15% of biomarker variation for energy, protein, and protein density respectively. The variations explained are significantly different between the calibration equations with or without the six psychosocial and diet variables for protein density (p = 0.02), but not for energy (p = 0.119) or protein intake (p = 0.077). The addition of psychosocial and diet behavior factors to calibration equations significantly increases the amount of total variance explained for protein density and their inclusion would be expected to strengthen the precision of calibration equations correcting self-report for measurement error.
