Examine the accuracy of parental weight perceptions of overweight children before and after the implementation of childhood obesity legislation that included BMI screening and feedback.
Statewide telephone surveys of parents of overweight (BMI > or = 85th percentile) Arkansas public school children before (n = 1,551; 15% African American) and after (n = 2,508; 15% African American) policy implementation were examined for correspondence between parental perception of child's weight and objective classification.
Most (60%) parents of overweight children underestimated weight at baseline. Parents of younger children were significantly more likely to underestimate (65%) than parents of adolescents (51%). Overweight parents were not more likely to underestimate, nor was inaccuracy associated with parental education or socioeconomic status. African-American parents were twice as likely to underestimate as whites. One year after BMI screening and feedback was implemented, the accuracy of classification of overweight children improved (53% underestimation). African-American parents had significantly greater improvements than white parents (P < 0.0001).
Parental recognition of childhood overweight may be improved with BMI screening and feedback, and African-American parents may specifically benefit. Nonetheless, underestimation of overweight is common and may have implications for public health interventions.
在实施包含BMI筛查和反馈的儿童肥胖立法前后，检查父母对超重儿童体重认知的准确性。
对阿肯色州公立学校超重儿童（BMI≥第85百分位数）的父母进行全州范围的电话调查，调查在政策实施前（n = 1551；15%为非裔美国人）和实施后（n = 2508；15%为非裔美国人）进行，以检查父母对孩子体重的认知与客观分类之间的一致性。
大多数（60%）超重儿童的父母在基线时低估了孩子的体重。年幼儿童的父母比青少年的父母更有可能低估（65%对51%）。超重的父母并不更有可能低估，不准确也与父母的教育程度或社会经济地位无关。非裔美国父母低估的可能性是白人父母的两倍。在实施BMI筛查和反馈一年后，超重儿童分类的准确性有所提高（低估率为53%）。非裔美国父母的改善明显大于白人父母（P < 0.0001）。
通过BMI筛查和反馈，父母对儿童超重的认知可能会得到改善，非裔美国父母可能会特别受益。尽管如此，超重的低估很常见，可能会对公共卫生干预产生影响。
