Little is known about parental recognition of their child's overweight status over time. The aim of this study was to examine the prevalence of parental misperceptions related to preschool children's weight in the last two decades.
Data come from the National Health and Nutrition Examination Survey from 1988 to 1994 (early survey; n=3839) and 2007 to 2012 (recent survey; n=3153). Parents were asked whether they considered their child, ages 2-5 years, to be overweight, underweight, or just about the right weight. We estimated the probability ratio (PR) between the two surveys for parents perceiving their overweight child as overweight.
Percentages of parents who inappropriately perceived their overweight child as just about the right weight was 96.6% and 94.9% for the early and recent survey, respectively. As high as 78.4% of parents perceived their obese child as just about the right weight in the recent survey. The probability of overweight/obese children being perceived as overweight in the early survey was 0.18 (95% confidence interval [CI]=0.14-0.22) and further lowered to 0.14 (95% CI=0.11-0.17) in the recent survey. After adjustment for sociodemographics and BMI z-scores of directly measured body weight, probability of being appropriately perceived by the parents declined by 30% between surveys (PR=0.70 [0.63, 0.78]).
There was a declining tendency among parents to perceive overweight children appropriately. Strategies are needed to explore how to encourage clinician discussions with parents about appropriate weight for their child and strengthen capacity for childhood obesity prevention.
关于父母对孩子超重状况随时间变化的认知情况，我们了解得很少。本研究的目的是调查过去二十年中父母对学龄前儿童体重的误解发生率。
数据来自1988年至1994年的国家健康与营养检查调查（早期调查；n = 3839）和2007年至2012年的调查（近期调查；n = 3153）。询问父母他们是否认为自己2至5岁的孩子超重、体重过轻或体重刚好合适。我们估计了两次调查之间父母将超重孩子视为超重的概率比（PR）。
早期调查和近期调查中，分别有96.6%和94.9%的父母将超重孩子误认作体重刚好合适。在近期调查中，高达78.4%的父母将肥胖孩子视为体重刚好合适。在早期调查中，超重/肥胖儿童被视为超重的概率为0.18（95%置信区间[CI]=0.14 - 0.22），在近期调查中进一步降至0.14（95% CI = 0.11 - 0.17）。在对社会人口统计学和直接测量体重的BMI z评分进行调整后，两次调查之间父母正确认知的概率下降了30%（PR = 0.70 [0.63, 0.78]）。
父母正确认知超重孩子的趋势呈下降态势。需要探索策略，以鼓励临床医生与父母讨论孩子的合适体重，并加强儿童肥胖预防能力。
