目得：为了评估社会期望特质的影响，倾向它）响应的方式与社会期望一致，对自我报告的水果，蔬菜，和宏量营养素intake.METHODS：61项食物频率问卷（FFQ），7项水果和蔬菜筛选，并结合水果和蔬菜摄入量的单一问题，完成了132名女性雇员在马萨诸塞州东部的5个健康中心。三种方法得出的水果和蔬菜摄入量以及FFQ中的大量营养素作为因变量拟合多元线性回归模型（总体和按种族/族裔和教育分列）;自变量包括24小时召回（24 HR）得出的3天平均摄入量和33分Marlowe-Crowne社会期望量表评分（回归系数反映了其对基于相对于24 HR的比较方法的膳食摄入量估计的影响）.结果：结果基于具有完整数据的93名妇女和FFQ导出的卡路里摄入量在450和4500千卡/天之间。在受过大学教育的女性中，FFQ得出的总热量估计值与社会期望特质的低报相关（例如，该组总热量摄入回归系数为-23.6千卡/天/点，而受教育程度低于大学的妇女为36.1千卡/天/点）（差异= 59.7千卡/天/点，95%置信区间（CI）= 13.2，106.2）。除了一个问题上，妇女，vith大学教育往往少报（差异= 0.103份/天/点，95%CI 0.003，0.203），社会期望性特征与自我报告的水果和蔬菜摄入量无关。结论：社会期望特质对FFQ报告的大量营养素摄入量的影响似乎因教育而异，但不因种族或民族而异。这项研究的结果可能对女性饮食和健康的流行病学研究具有重要意义。(C)2001 Elsevier Science Inc.

PURPOSE: To evaluate the effect of social desirability trait, the tendency it) respond in a manner consistent with societal expectations, on self-reported fruit, vegetable, and macronutrient intake.METHODS: A 61-item food frequency questionnaire (FFQ), 7-item fruit and vegetable screener, and a single question on combined fruit and vegetable intake were completed by 132 female employees at five health centers in eastern Massachusetts. Intake of fruit and vegetables derived front all three methods and macronutrients from the FFQ were fit as dependent variables in multiple linear regression models (overall and by race/ ethnicity and education); independent variables included 3-day mean intakes derived from 24-hour recalls (24HR) and score on the 33-point Marlowe-Crowne Social Desirability scale (the regression coefficient for which reflects its effect on estimates of dietary intake based on the comparison method relative to 24HR).RESULTS: Results are based on the 93 women with complete data and FFQ-derived Caloric intake between 450 and 4500 kcal/day. In women with college education, FFQ-derived estimates of total caloric were associated with under- reporting by social desirability trait (e.g., the regression coefficient for total caloric intake was -23.6 kcal/day/point in that group versus 36.1 kcal/day/point in women with education less than college) (difference = 59.7 kcal/day/point, 95% confidence interval (CI) = 13.2, 106,2). Except for the single question on which women,vith college education tended to under-report (difference =.103 servings/day/point, 95% Cl 0.003, 0.203), there was no association of social desirability trait with self-reported fruit and vegetable intake.CONCLUSIONS: The effect of social desirability trait on FFQ reports of macronutrient intake appeared to differ by education, but not by ethnicity or race. The results of this study may have important implications for epidemiologic studies of diet and health in women. (C) 2001 Elsevier Science Inc. All rights reserved.
