P>；这项研究旨在通过纳入超重和肥胖患病率的增加、新的相关合并症的发现以及全国医疗支出的上升，来更新加拿大因超重和肥胖而造成的疾病经济负担的估计。使用基于流行率的疾病成本方法从社会角度估计了负担。对18种相关合并症风险的文献综述的结果与加拿大超重和肥胖的流行率相结合，以估计每种共病可归因于超重和肥胖的程度。直接费用是从国家卫生支出数据库中提取的，并使用主要来自加拿大疾病经济负担的权重分配给每种共病。研究显示，2006年加拿大因超重和肥胖造成的直接损失总额为60亿美元，其中66%可归因于肥胖。这相当于2006年加拿大卫生总支出的4.1%。纳入新发现的合并症后，肥胖的直接成本估计增加了25%，而国民医疗支出的增加则占到了19%。减少超重和肥胖的政策可能会为加拿大的医疗体系节省数百万美元。
P>This study is to update the estimates of the economic burden of illness because of overweight and obesity in Canada by incorporating the increase in prevalence of overweight and obesity, findings of new related comorbidities and rise in the national healthcare expenditure. The burden was estimated from a societal perspective using the prevalence-based cost-of-illness methodology. Results from a literature review of the risks of 18 related comorbidities were combined with prevalence of overweight and obesity in Canada to estimate the extent to which each comorbidity is attributable to overweight and obesity. The direct costs were extracted from the National Health Expenditure Database and allocated to each comorbidity using weights principally from the Economic Burden of Illness in Canada. The study showed that the total direct costs attributable to overweight and obesity in Canada were $6.0 billion in 2006, with 66% attributable to obesity. This corresponds to 4.1% of the total health expenditures in Canada in 2006. The inclusion of newly identified comorbidities increased the direct cost estimates of obesity by 25%, while the rise in national healthcare expenditure accounted for a 19% increase. Policies to reduce being overweight and obese could potentially save the Canadian healthcare system millions of dollars.
