About the Study
Boston Puerto Rican Health Study
Puerto Rican adults living on the United States mainland have documented health disparities; however, little research has been conducted with this second largest Hispanic subgroup. Our long-term goal is to understand the complex interactions of diet and other behavioral and environmental factors, genetics, and psychosocial stress on the high and apparently increasing prevalence of cardiovascular disease (CVD) risk factors in Puerto Rican adults.
Importantly, the Puerto Rican population differs considerably in ancestral genetic history and in exposures to known risk factors from other Hispanic groups. They have unique dietary intake patterns, as well as social, cultural, and environmental structures that contribute and affect reaction to stressors.
As this group is rapidly growing, understanding the reasons for this risk is of great importance. Our initial funding period for the Boston Puerto Rican Center for Population Health and Health Disparities (BPR-CPHHD, 2003-08) focused on the role of stress on physical disability and cognitive decline through physiological dysregulation or “allostatic load.” During that investigation, it became clear that risk factors for CVD were highly prevalent. These findings are in contrast to the commonly held belief that there is a Hispanic paradox-lower heart disease and mortality despite greater poverty.
The overall aim for the Center is, therefore, to extend follow-up and to measure and analyze relevant characteristics and CVD risk factors, and to add additional contextual and outcome measures for CVD risk in this established cohort of Puerto Rican adults; this will allow us to better understand the dynamics of these disparities.
