Overweight children are at an increased risk of premature mortality and disease in adulthood. Parental perceptions and clinical definitions of child obesity differ, which may lessen the effectiveness of interventions to address obesity in the home setting. The extent to which parental and objective weight status cut-offs diverge has not been documented.
To compare parental perceived and objectively derived assessment of underweight, healthy weight, and overweight in English children, and to identify sociodemographic characteristics that predict parental under- or overestimation of a child's weight status.
Cross-sectional questionnaire completed by parents linked with objective measurement of height and weight by school nurses, in English children from five regions aged 4-5 and 10-11 years old.
Parental derived cut-offs for under- and overweight were derived from a multinomial model of parental classification of their own child's weight status against school nurse measured body mass index (BMI) centile.
Measured BMI centile was matched with parent classification of weight status in 2976 children. Parents become more likely to classify their children as underweight when they are at the 0.8th centile or below, and overweight at the 99.7th centile or above. Parents were more likely to underestimate a child's weight if the child was black or South Asian, male, more deprived, or the child was older. These values differ greatly from the BMI centile cut-offs for underweight (2nd centile) and overweight (85th).
Clinical and parental classifications of obesity are divergent at extremes of the weight spectrum.
超重儿童成年后过早死亡和患病的风险增加。父母对儿童肥胖的认知与临床定义不同，这可能会降低家庭环境中肥胖干预措施的有效性。父母与客观体重状况临界值的差异程度尚未有文献记载。
比较英国儿童中父母感知的以及客观得出的体重过轻、健康体重和超重的评估情况，并确定预测父母低估或高估儿童体重状况的社会人口学特征。
对来自五个地区、年龄在4 - 5岁和10 - 11岁的英国儿童，由父母填写横断面问卷，并由学校护士对其身高和体重进行客观测量。
根据父母对自己孩子体重状况的分类与学校护士测量的体重指数（BMI）百分位数的多项模型，得出父母对体重过轻和超重的临界值。
在2976名儿童中，测量的BMI百分位数与父母对体重状况的分类相匹配。当孩子处于第0.8百分位数或更低时，父母更有可能将其归类为体重过轻；当处于第99.7百分位数或更高时，归类为超重。如果孩子是黑人或南亚人、男性、贫困程度更高或年龄较大，父母更有可能低估孩子的体重。这些数值与体重过轻（第2百分位数）和超重（第85百分位数）的BMI百分位数临界值有很大差异。
在体重范围的极端情况下，肥胖的临床分类和父母分类存在差异。
