Researchers from the University of Michigan claim that the struggling U.S. economy ripples down to poor countries in Latin America like Honduras.

The study is published in International Journal of Health Services.

The researchers say that the high unemployment rate among Latino immigrants in the U.S. has disabled them from financially helping their chronically ill family members in their home countries.

Latino immigrants have been especially hard-hit during the nation's financial crisis, partly due to major job losses in housing construction, which is a leading source of employment for them. Between the end of 2007 and the end of 2008, the percentage of working-age Latinos with jobs fell at almost twice the rate for the overall population.

Lead study author John D. Piette said remittance payments from relatives living in the United States are a major source of income for chronically ill people in Latin America.

"It may be hard to imagine causal linkages between a factory closing in Michigan or a pay cut for restaurant workers in Iowa and the health care of someone in rural Honduras," Piette said. "But the results of this study suggest that economic stresses in the United States ripple outward."

Researchers surveyed over 600 chronically ill adults in poverty-stricken Honduras and found that more than 50 percent reported relatives living outside of the country, and of that group, two thirds received remittances. Seventy-four percent of those receiving the support reported a decrease over the prior year, mostly due to job losses among relatives abroad.

Decreases in remittance payments averaged roughly $700 per year - a significant loss in a country where many families live on less than $200 per month.

Patients receiving reduced support from families overseas were less likely to visit a hospital for a health emergency and were more likely to take less of their medications than prescribed because of financial strain.

Among patients receiving less aid from relatives abroad, nearly 40 percent said they were sometimes unable to buy medications and roughly a third skipped medical visits. Others reported spending less on basic needs such as food and education.

The study was conducted in Santa Cruz de Yojoa, in North Central Honduras, among patients making non-urgent visits to primary care centers.

Remittances were most common among patients who had less education, larger families, and multiple chronic health problems including hypertension, diabetes, arthritis, and cardiovascular disease.

All respondents reported that they had to pay 100 percent for their health care out of pocket, with no access to insurance.

"Unfair labor practices, language barriers and low education levels for Central American immigrants make it likely that they will continue to face economic hardships in the U.S.," Piette said. "These immigrants have made astounding and noble sacrifices by sending aid to relatives in their home country despite their low wages. Those commitments may be unsustainable without a strong recovery in the U.S. economy."
