目标。调查4-5岁儿童超重是否会增加公共资助的儿童期医疗费用，并探索超重的时间和持续时间对健康成本的作用。澳大利亚儿童纵向研究(20042009-2008年)和澳大利亚公共健康保险提供商联邦医疗保险(Medicare)的相关记录。使用两部分模型和一部分广义线性模型(GLM)估计了超重状况对儿童在5年内发生的非医院医疗保险费用的影响。所有模型都控制了人口统计、社会经济和父母特征。在4-5岁时超重与显著更高的药品和医疗费用有关。结果表明，在2004-2005年间，对于所有4岁和5岁的儿童来说，超重儿童的5年医疗保险账单比正常体重儿童高出980万澳元。动态分析结果显示，儿童超重的费用是同时发生的，超重持续时间与5岁以后超重儿童的医疗费用呈正相关。这项研究表明，儿童超重和肥胖给公共卫生系统带来的经济负担甚至发生在小学的头5年。
Objective. To investigate whether childhood overweight at age 4-5 increases publicly funded health care costs during childhood, and to explore the role of timing and duration of overweight on health costs.Data Sources. The Longitudinal Study of Australian Children (2004-2008) and linked records from Medicare, Australia's public health insurance provider (20042009).Study Design. The influence of overweight status on non-hospital Medicare costs incurred by children over a 5-year period was estimated using two-part models and one-part generalized linear models (GLM). All models controlled for demographic, socioeconomic, and parental characteristics.Principal Findings. Being overweight at age 4-5 is associated with significantly higher pharmaceutical and medical care costs. The results imply that for all children aged 4 and 5 in 2004-2005, those who were overweight had a combined 5-year Medicare bill that was AUD$9.8 million higher than that of normal weight children. Results from dynamic analyses show that costs of childhood overweight occur contemporaneously, and the duration of overweight is positively associated with medical costs for children who became overweight after age 5.Conclusions. This study reveals that the financial burden to the public health system of childhood overweight and obesity occurs even during the first 5 years of primary school.
