The objective of the study was to examine time trends and differences in medical expenditures between noncitizens, foreign-born, and US-born citizens.
We used multi-year Medical Expenditures Panel Survey (2000-2008) data on noninstitutionalized adults in the United States (N=190,965). Source specific and total medical expenditures were analyzed using regression models, bootstrap prediction techniques, and linear and nonlinear decomposition methods to evaluate the relationship between immigration status and expenditures, controlling for confounding effects.
We found that the average health expenditures between 2000 and 2008 for noncitizens immigrants ($1836) were substantially lower compared with both foreign-born ($3737) and US-born citizens ($4478). Differences were maintained after controlling for confounding effects. Decomposition techniques showed that the main determinants of these differences were the availability of a usual source of health care, insurance, and ethnicity/race.
Lower health care expenditures among immigrants result from disparate access to health care. The dissipation of demographic advantages among immigrants could prospectively produce higher pressures on the US health care system as immigrants age and levels of chronic conditions rise. Barring a shift in policy, the brunt of the effects could be borne by an already overextended public health care system.
本研究旨在考察非公民、外国出生和美国出生公民之间的医疗支出的时间趋势和差异。
我们使用了美国非住院成年人的多年度医疗支出调查(2000-2008 年)数据(N=190965)。使用回归模型、引导预测技术以及线性和非线性分解方法分析了特定来源和总医疗支出,以评估移民身份与支出之间的关系,同时控制混杂效应。
我们发现,2000 年至 2008 年间,非公民移民的平均健康支出(1836 美元)明显低于外国出生者(3737 美元)和美国出生公民(4478 美元)。在控制混杂效应后,差异仍然存在。分解技术表明,这些差异的主要决定因素是是否有常规医疗服务来源、保险以及族裔/种族。
移民的医疗保健支出较低是由于获得医疗保健服务的机会不均等造成的。随着移民年龄的增长和慢性病水平的上升,移民人口的优势逐渐消失,可能会给美国的医疗保健系统带来更大的压力。如果政策不发生转变,那么现有的公共医疗保健系统可能会首当其冲地受到影响。
