背景。社会期望 (SocD) 可能会对儿童自我报告的健康行为和态度产生偏见，并混淆与健康结果测量的关系。方法。 95 名 8 至 10 岁的非裔美国女孩完成了饮食回忆、身体活动检查表、与饮食和身体活动相关的心理社会调查问卷；以及 3 天的体力活动监测。通过将身体活动、饮料摄入量和体重指数 (BMI) 的指定标准测量值与横截面回归模型中与活动、饮料偏好以及身体形象和体重问题相关的自我报告测量值进行比较，研究了潜在的 SocD 构建偏差。 SocD 使用系数变化回归分析评估了自我报告行为与 BMI 之间关联的潜在混淆。结果。控制年龄和 BMI 后，高估自我报告的活动 (P = 0.02)、低估甜饮料偏好 (P = 0.02) 以及较低的体重关注度和节食行为 (P < 0.05) 与 SocD 相关。 SocD 发现自我报告的体力活动和能量摄入与 BMI 之间的关联存在混淆。结论。在 8 至 10 岁的非裔美国女孩中，SocD 被发现对饮食和身体活动的自我报告存在偏见，并且混淆了 BMI 与自我报告的身体活动和能量摄入之间的关联。需要测量和控制 SoCD 偏差的方法，以减少饮食、身体活动和健康结果之间关系的潜在扭曲。 (C) 2004 年癌症预防研究所和 Elsevier Inc. 保留所有权利。
Background. Social desirability (SocD) may bias children's self-reported health behaviors and attitudes and confound relationships with health outcome measures.Methods. Ninety-five, 8- to 10-year-old African-American girls completed dietary recalls, a physical activity checklist, psychosocial questionnaires related to diet, and physical activity; and 3 days of physical activity monitoring. Potential SocD construct bias was investigated by comparing designated criterion measures of physical activity, beverage intake, and body mass index (BMI) with respective self-reported measures related to activity, beverage preferences, and body image and weight concerns in cross-sectional regression models. Potential confounding by SocD of associations between self-reported behaviors with BMI was assessed using change-in-coefficient regression analyses.Results. Controlling for age and BMI, overestimates of self-reported activity (P = 0.02), underestimates of sweetened beverage preferences (P= 0.02), and lower ratings of weight concems and dieting behaviors (P's < 0.05) were related to SocD. Confounding by SocD of associations between self-reported physical activity and energy intake with BMI was found.Conclusions. In 8- to 10-year-old African-American girls, SocD was found to bias self-reports of diet and physical activity and confound associations between BMI and self-reported physical activity and energy intake. Methods to measure and control SocD bias are needed to reduce potential distortion of relationships between diet and physical activity and health outcomes.
