Many parents do not recognize that their young children are overweight or obese, possibly because epidemiological cutpoints may not reflect parent perceptions of overweight. We determined whether any Body mass index (BMI) cutpoint reliably triggers parent concern, drawing on the first wave (2004) of the Longitudinal Study of Australian Children (LSAC). BMI (kg/m(2)) and parent concern about their child's weight categorized in three different ways (any, moderately or greater, very) were available for 4,983 children aged 4-5. We used logistic regression to assess the relationship between BMI and parent concern, and receiver operating characteristic (ROC) curves to determine BMI cutpoints that best discriminate parent concern. Parent concern about their pre-schoolers' weight related only modestly to body mass and was not triggered by any definable BMI threshold. This may partly explain why current childhood obesity policies are ineffective, as they typically require individual concern leading to family behavioural change.
许多家长并未意识到自己的幼儿超重或肥胖，这可能是因为流行病学的切点可能无法反映家长对超重的认知。我们利用澳大利亚儿童纵向研究（LSAC）的第一波数据（2004年），确定是否有任何体重指数（BMI）切点能可靠地引发家长的关注。4983名4至5岁儿童的BMI（千克/平方米）以及家长对孩子体重的关注被分为三种不同方式（任何、中度或更高、非常）。我们使用逻辑回归来评估BMI与家长关注之间的关系，并使用受试者工作特征（ROC）曲线来确定最能区分家长关注的BMI切点。家长对学龄前儿童体重的关注与体重仅适度相关，且未被任何可定义的BMI阈值触发。这可能部分解释了为何当前的儿童肥胖政策无效，因为它们通常需要个人关注才能导致家庭行为改变。
