Mexicans-Americans born and raised in the United States are more likely to suffer from conditions such as diabetes, high blood pressure and high cholesterol than those who emigrate from Mexico, according to a new study from the University of Southern California.
The difference may be due to poor nutrition and less physical activity among native-born Mexican-Americans. Also individuals who leave Mexico for the United States may be fitter than the ones who stay behind.
"One possible explanation is that people who immigrate are healthy to begin with and they may also have come here with better health habits," said Eileen Crimmins, lead author of the study and professor of gerontology at USC. "The generation born here has adopted American traits such as smoking and eating at fast food restaurants that were not as accessible in more traditional parts of Mexico."
In a comparison of risk factors across ethnic groups, researchers from the USC Davis School of Gerontology and the UCLA School of Medicine found that U.S. born Mexican-Americans are significantly worse off not just than whites but also Mexican-born immigrants. The only group at greater risk for disease than the U.S.-born Mexican-American community is the black population.
The research appears in the current issue of the American Journal of Public Health and addresses a contradiction found in other studies known as the Hispanic Paradox a claim that Hispanics in the United States are healthier than whites despite being poorer and less educated.
Instead, this study shows that Mexicans-Americans born in the United States are less healthy than whites of the same socioeconomic background. Only foreign-born Hispanics match their white counterparts. These fit immigrants tip the scales for the Hispanic population, skewing numbers that would otherwise indicate an unhealthy Hispanic population.
The findings refute the Hispanic Paradox and support the hypotheses that people who are not healthy tend to stay in their home country and some immigrants living in America who become sick may return home.
"By gaining the healthiest of migr's from Mexico, the U.S. Hispanic population appears to be a healthy community, one that rivals the white population in low mortality rates and positive health factors," said Crimmins.
Crimmins says the distinction is significant because a misperception of a robust Hispanic population may affect policy decisions.
