To assess and compare health care costs for normal-weight, overweight and obese Australians.
DESIGN, SETTING AND PARTICIPANTS: Analysis of 5-year follow-up data from the Australian Diabetes, Obesity and Lifestyle study, collected in 2004-2005. Data were available for 6140 participants aged >or= 25 years at baseline.
Direct health care cost, direct non-health care cost and government subsidies associated with overweight and obesity, defined by both body mass index (BMI) and waist circumference (WC).
The annual total direct cost (health care and non-health care) per person increased from $1472 (95% CI, $1204-$1740) for those of normal weight to $2788 (95% CI, $2542-$3035) for the obese, however defined (by BMI, WC or both). In 2005, the total direct cost for Australians aged >or= 30 years was $6.5 billion (95% CI, $5.8-$7.3 billion) for overweight and $14.5 billion (95% CI, $13.2-$15.7 billion) for obesity. The total excess annual direct cost due to overweight and obesity (above the cost for normal-weight individuals) was $10.7 billion. Overweight and obese individuals also received $35.6 billion (95% CI, $33.4-$38.0 billion) in government subsidies. Comparing costs by weight change since 1999-2000, those who remained obese in 2004-2005 had the highest annual total direct cost. Cost was lower in overweight or obese people who lost weight or reduced WC compared with those who progressed to becoming, or remained, obese.
The total annual direct cost of overweight and obesity in Australia in 2005 was $21 billion, substantially higher than previous estimates. There is financial incentive at both individual and societal levels for overweight and obese people to lose weight and/or reduce WC.
评估和比较澳大利亚正常体重、超重和肥胖人群的医疗保健费用。
设计、设置和参与者：对澳大利亚糖尿病、肥胖和生活方式研究的 5 年随访数据进行分析，这些数据收集于 2004-2005 年。基线时有 6140 名年龄大于等于 25 岁的参与者的数据可用。
超重和肥胖相关的直接医疗保健费用、直接非医疗保健费用和政府补贴，这些定义为体重指数（BMI）和腰围（WC）。
每年每人的直接总费用（医疗保健和非医疗保健）从正常体重者的 1472 美元（95%CI，1204-1740 美元）增加到肥胖者的 2788 美元（95%CI，2542-3035 美元），无论采用哪种定义方法（BMI、WC 或两者兼用）。2005 年，澳大利亚年龄大于等于 30 岁的超重人群的直接总成本为 65 亿美元（95%CI，58 亿-73 亿美元），肥胖人群的直接总成本为 145 亿美元（95%CI，132 亿-157 亿美元）。由于超重和肥胖而导致的每年额外的直接费用（高于正常体重个体的成本）为 107 亿美元。超重和肥胖个体还获得了 356 亿美元（95%CI，334-380 亿美元）的政府补贴。与 1999-2000 年以来的体重变化相比，2004-2005 年仍肥胖的个体的年度总直接费用最高。与体重增加或仍肥胖的个体相比，体重减轻或腰围减少的超重或肥胖个体的直接总费用较低。
2005 年澳大利亚超重和肥胖的年直接总成本为 210 亿美元，明显高于以往的估计。超重和肥胖个体减轻体重和/或减少腰围对个人和社会都有经济上的激励作用。
