[(Title)] Study: Immigrants have lower health-care costs than people born in US.

The report from researchers at Harvard Medical School and Tufts University examined all peer-reviewed studies since 2000 on immigrants' health-care costs in the United States.

哈佛医学院和塔夫茨大学研究人员的报告审查了自2000年以来关于移民在美国的医疗保健费用的所有同侪审查研究。

It found that immigrants' health-care expenditures were one-half to two-thirds those of people born in the U.S.

调查发现，移民医疗支出占出生在美国人口支出的半数至三分之二。

"Overall, immigrants almost certainly paid more toward medical expenses than they withdrew, providing a low-risk pool that subsidized the public and private health insurance markets,"  the study states.

It comes as the Trump administration is reportedly considering new rules that would make it harder for legal immigrants to become citizens if they have used health-care programs like ObamaCare insurance or the Children's Health Insurance Program.

据报道，特朗普政府正在考虑新规则，如果合法移民使用奥巴马医保保险或儿童健康保险计划等保健方案，他们成为公民会更加困难。

Among immigrants in the country illegally, the study finds the group makes up 1.4 percent of U.S. health-care spending, but is 5 percent of the population.

调查发现，在非法移民中，这一群体占美国医疗保健支出的1.4%，但占总人口的5%。

Even when examining only immigrants who had health insurance, the study found they lower health spending than U.S. born people with insurance.  Spending of insured immigrants was 52 percent lower than that of insured U.S.-born individuals.

即使只检查那些有健康保险的移民，研究还发现，他们的健康支出低于美国出生的有保险者。

Several of the researchers are members of Physicians for a National Health Program, a group that supports single-payer health care.

一些研究人员是国家健康计划的医生成员，该计划支持单一支付者医疗保健。

"Our findings show that immigrants are clearly bringing down per capita health care costs and are likely subsidizing care for native-born Americans,"  one of the authors, Dr. J. Wesley Boyd,

哈佛医学院精神病学副教授J. Wesley Boyd博士说：“我们的调查结果表明，移民显然正在降低人均保健费用，并可能补贴美国出生者们的医疗服。"

an associate professor of psychiatry at Harvard Medical School, said in a statement.  "Instead of attacking immigrants for driving up costs, we should recognize their proven economic contributions."

他在一份声明中说，"我们不应因为成本上升而攻击移民，而应承认他们已证明的经济贡献。”
