Despite high levels of cardiovascular risk factors, Mexican Americans paradoxically have a lower prevalence of cardiovascular disease.
A possible explanation is that conventional cardiovascular risk factors have a lesser impact on this ethnic group.
In the present study, a 7-to 8-year follow-up of the San Antonio Heart Study cohort was used to estimate total and cardiovascular disease mortality and their association with baseline risk factors.
A total of 2,629 Mexican Americans form the basis of this study, and 1,136 non-Hispanic whites from the same cohort served as the comparison group.
The age-and sex-adjusted rates for total death and cardiovascular disease death were somewhat higher in Mexican Americans than non-Hispanic whites (rate ratio for total mortality=1.4,95% confidence interval 1.0-2.0 ; and rate ratio for cardiovascular mortality=1.3,95% confidence interval 0.7-2.4).
After adjustment for sex, age, and socioeconomic status in multivariate analyses, current smoking, diabetes, high cholesterol, and hypertension were positively associated with all-cause mortality and cardiovascular disease mortality in Mexican Americans.
Overall, these risk factors accounted for 45% of all-cause mortality and 55% of cardiovascular disease mortality in this ethnic group.
In comparison, the risk factors accounted for 46% of all-cause mortality and 46% of cardiovascular disease mortality in non-Hispanic whites. (...)
