Asthma Risk After Moving to the U.S.

Asthma Risk After Moving to the U.S.

The prevalence of asthma reportedly is higher among U.S.-born Hispanics/Latinos than those who’ve relocated here. But it’s not known whether these findings are consistent across Hispanic/Latino groups. In a retrospective study published online on February 2 in the American Journal of Preventive Medicine, lead authors Elina Jerschow, M.D., and Garrett Strizich, M.P.H., found that the effect on asthma risk from relocating to the U.S. differs among various Hispanic/Latino groups. The study involved more than 15,000 U.S.-dwelling participants in the NIH-funded Hispanic Community Health Study (HCHS)/Study of Latinos (SOL). They were questioned about their asthma histories from birth through age 30. Foreign-born Dominicans and Mexicans (and to a lesser extent Puerto Ricans) had higher rates of asthma after relocating to the U.S. compared with counterparts the same age who relocated to the U.S. when they were older. Dr. Jerschow is associate professor of medicine and attending physician at Montefiore.
