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.
With this new peak, the number of cases of the viral infection now stands at 4,029 for the year.
This is the third time this year that the disease, spread through the bite of the Aedes mosquito, has hit epidemic levels.
Highlights of the research include:
The role of pesticides (eg. Paraquat and Dieldrin) as potential risk factors for Parkinson's disease, a role suggested by both epidemiological statistics and laboratory evidence.
The threat of toxic agents to damage neurons by causing the accumulation of harmful proteins.
Intraneuronal protein aggregates as markers of Parkinson's pathology, based on work carried out at The Parkinson's Institute indicating that these aggregates could be formed as a consequence of toxic exposure.
The importance of targeting a specific protein, alpha-synuclein, in order to achieve neuroprotection in Parkinson's
The role of inflammation in the development of Parkinson's disease and the possibility that anti-inflammatory drugs could be beneficial to patients.
The possibility that nicotine may act as a neuroprotective agent.
A group, led by Tao Xia of the East China Normal University, found that diabetic rats fed the extract had only 5% less plasma insulin and 8% fewer insulin-positive (beta) cells compared to normal healthy rats (Journal of the Science of Food and Agriculture, 87(9) 1753-7 2007).
Xia says: 'pumpkin extract is potentially a very good product for pre-diabetic persons, as well as those who have already developed diabetes.' He adds that although insulin injections will probably always be necessary for these patients, pumpkin extract could drastically reduce the amount of insulin they need to take.
The manufacturer has predicted that 5 million to 6 million Americans a year will buy the drug.
