Abstract 15938: Disaggregating Cardiovascular Disease Mortality Among Hispanic Subgroups
Background: Hispanics are currently the largest minority group in the US and face a disproportionate burden of cardiovascular disease (CVD) risk factors. Hispanics paradoxically experience lower mortality rates as compared to their non-Hispanic white (NHW) counterparts. This phenomenon has been largely observed in Mexicans and it is unknown whether this holds true for other Hispanic subgroups, and if these favorable trends persist over time.
Methods: We examined data from the National Center for Health Statistics U.S. Mortality Multiple Cause-of-Death data from 2003-2011 to identify CVD deaths for the three largest Hispanic subgroups in the U.S. (Mexicans, Puerto Ricans, and Cubans). CVD deaths were extracted from mortality records using the underlying cause of death based on ICD-10 coding (I00-I09, I11, I13, I20-I51.9, I60-I69). Race/ethnicity was recorded on death certificates by the funeral director using state guidelines. Population estimates were calculated using linear interpolation from 2000 and 2010 U.S. Census.
Results: The study sample consisted of all-cause deaths for the three largest Hispanic subgroups in the U.S.: Mexicans (n=689,162), Puerto Ricans n=154,402), and Cubans (n=117,751), compared to NHWs (n=17,699,740). Cubans and Mexicans were, on average, younger at time of incident CVD death as compared to NHWs (73 vs. 79, respectively). Overall, CVD mortality trends decreased from 2003-2011 for all groups (p<0.001), but rate differences between groups vary substantially, with Puerto Ricans exhibiting similar mortality patterns to NHWs and Mexicans experiencing the lower mortality (Figure 1).
Conclusions: Significant differences in CVD mortality rates and trends were found between the three largest Hispanic subgroups in the US. These findings suggest that the current aggregate classification of Hispanics masks heterogeneity in CVD mortality reporting, leading to an incomplete understanding of health risks and outcomes.
