父母报告的身高和体重通常用于估计儿童的BMI和超重状况。父母报告数据的质量尚未与美国所有种族/族裔群体的全国范围内的测量数据进行比较。在两次全国健康访谈调查（1999-2004年全国健康访谈调查（NHIS）和2003-2004年全国儿童健康调查（NSCH））中，父母报告的2-17岁儿童的身高和体重与1999-2004年全国健康和营养检查调查（NHANES）的测量值进行了比较。与测量数据相比，父母报告的数据高估了儿童超重的采访调查。例如，2-17岁儿童的超重率为25%（s.e. 0.2)使用父母报告的NHIS数据与16%（s.e. 0.6)使用测量的NHANES数据。父母报告的数据高估了年幼儿童的超重，但低估了年长儿童的超重。报告的估计数和测量的估计数之间的差异主要是由于报告的幼儿身高。对于2-11岁的儿童，NHIS报告的平均身高比NHANES测量的平均身高低3-6 cm（P < 0.001），而16-17岁的儿童无差异。测量数据仍然是监测儿童超重的金标准。虽然这项分析比较了调查人群的平均值，而不是父母报告和测量的个人数据，但全国代表性数据的结果加强了以前基于小样本的建议，即父母报告的数据不应用于估计学龄前和小学学龄儿童的超重患病率。
Parent-reported height and weight are often used to estimate BMI and overweight status among children. The quality of parent-reported data has not been compared to measured data on a national scale for all race/ethnic groups in the United States. Parent-reported height and weight for 2-17-year-old children in two national health interview surveys-the 1999-2004 National Health Interview Survey (NHIS) and the 2003-2004 National Survey of Children's Health (NSCH)-were compared to measured values from a national examination survey-the 1999-2004 National Health and Nutrition Examination Survey (NHANES). Compared to measured data, parent-reported data overestimated childhood overweight in both interview surveys. For example, overweight prevalence among 2-17-year-olds was 25% (s.e. 0.2) using parent-reported NHIS data vs. 16% (s.e. 0.6) using measured NHANES data. Parent-reported data overestimated overweight among younger children, but underestimated overweight among older children. The discrepancy between reported and measured estimates arose mainly from reported height among very young children. For children aged 2-11 years, the mean reported height from NHIS was 3-6 cm less than mean measured height from NHANES (P < 0.001) vs. no difference among children aged 16-17 years. Measured data remains the gold standard for surveillance of childhood overweight. Although this analysis compared mean values from survey populations rather than parent-reported and measured data for individuals, the results from nationally representative data reinforce previous recommendations based on small samples that parent-reported data should not be used to estimate overweight prevalence among preschool and elementary school-aged children.
