Approximately 8% of the U.S. population suffers from asthma, a chronic condition. It poses a substantial economic burden to society in the form of lost productivity and healthcare costs. We use the Medical Expenditure Panel Survey 2002-2010 to quantify the lifetime costs of asthma at each age, the impact of adult asthma on earnings and choice of occupation, and the impact of childhood asthma on parental income. We developed a framework to estimate the present discounted value of the cumulative lifetime asthma-related healthcare costs and lost productivity experienced by an individual after onset. This approach allows for age- and asthma duration-related variability in annual costs as well as for the intermittent nature of asthma symptoms. Estimated asthma-related annual healthcare expenditures across all life stages are $700-$2,200 (2010 U.S. dollars). Lost annual earnings among individuals aged 30-49 are over $4,000 (2010 U.S. dollars). The present discounted value of the cumulative lifetime healthcare costs and lost productivity for a new case of asthma is estimated at $36,500 using the 3% discount rate (2010 U.S. dollars). The economic burden of asthma is substantial and larger than previously estimated, reflecting expenditures on treatment and lost earnings.
美国约8%的人口患有哮喘这种慢性病。它以生产力损失和医疗成本的形式给社会带来了巨大的经济负担。我们利用2002 - 2010年医疗支出面板调查来量化各年龄段哮喘的终身成本、成人哮喘对收入和职业选择的影响，以及儿童哮喘对父母收入的影响。我们开发了一个框架来估计个体发病后累积终身与哮喘相关的医疗成本和生产力损失的现值。这种方法考虑了年度成本中与年龄和哮喘病程相关的变异性以及哮喘症状的间歇性。所有生命阶段与哮喘相关的年度医疗支出估计为700 - 2200美元（2010年美元）。30 - 49岁人群的年度收入损失超过4000美元（2010年美元）。使用3%的贴现率，新发病例哮喘的累积终身医疗成本和生产力损失的现值估计为36500美元（2010年美元）。哮喘的经济负担巨大，且比之前估计的更大，反映了治疗支出和收入损失。
