ABSTRACT Hispanics have less favorable cardiovascular risk profiles relative to other groups, although little is known regarding variability in risk profiles according to country of origin. Our goal was to examine the association of cardiovascular risk factors with country of origin and acculturation in a cohort of middle-aged Hispanic women.
Baseline data for participants at the New Jersey Site of the Study of Women's Health Across the Nation (SWAN).
419 women, aged 42-52 years, comprising 142 non-Hispanic Whites and 277 Hispanic: Central American (n = 29), South American (n = 106), Puerto Rican (n = 56), Dominican (n = 42) and Cuban (n = 44).
BMI, smoking, blood pressure, lipid profiles, and presence of hypertension, hyperlipidemia, diabetes and metabolic syndrome were compared using univariate and multivariable models.
LDL and HDL varied significantly across Hispanic subgroups (overall P < or = .05). Prevalence of metabolic syndrome was greatest in Puerto Rican women (48.2% vs 40.0%, 35.0%, 13.9% and 29.3% in Central American, South American, Dominican and Cuban women, respectively, P = .016). Central American women were least likely to smoke (P < .05 vs Puerto Rican, Cuban and South American). Prevalence of hypertension and diabetes were similar across groups. Differences in lipids and metabolic syndrome were not explained by acculturation, financial strain, education, physical activity, smoking or dietary fat intake.
There is significant heterogeneity in cardiovascular risk status among middle-aged Puerto Rican, Cuban, Dominican, Central American and South American women, not explained by acculturation or socioeconomic indicators. These differences may be important for targeting screening and preventive interventions.

    • "In addition to the genetic heterogeneity, substantial variation in socioeconomic status and culture, and other risk factors have been also noted among the various subgroups of Hispanics. For example, Derby et al. found that there is significant heterogeneity in cardiovascular risk status among middle-aged Puerto Rican, Cuban, Dominican, Central American and South American women (Derby et al. 2010). In addition, the subgroups of Hispanics who live at different geographic locations are exposed to various environments that are mostly determined by the places they live. "

    ABSTRACT: A less favorable cardiovascular risk factor profile but paradoxically lower cardiovascular morbidity and mortality have been observed in Hispanics--a pattern often referred to as the Hispanic paradox. It has been proposed that the specific genetic susceptibility of this admixed population and gene-environment interactions may partly explain the paradox. During the past few years, there have been major advances in the identification of genetic risk factors using genome-wide association studies (GWAS) for cardiovascular disease, especially in Caucasians. However, no GWAS of cardiovascular disease have been reported in Hispanics. In the Costa Rican Heart Study, we reported both the consistency and disparity of genetic effects on risk of coronary heart disease (CHD) between Hispanics and other ethnic groups. We demonstrated that the improvement in the identified genetic markers on discrimination of CHD in Hispanics was modest. Future genetic research on Hispanics should consider the diversity in genetic structure, lifestyle, and socioeconomics among various subpopulations and comprehensively evaluate potential gene-environment interactions in relation to cardiovascular risk.

    ABSTRACT: Reproductive health can be a reflection of overall health. It follows that abnormalities of reproductive milestones may be a manifestation of unhealthy aging. Since 1994, the Study of Women's Health Across the Nation (SWAN) has assessed how menopause and the process of that transition may affect future health. Themes have emerged from SWAN associating patterns of hormones and symptoms with metabolic status.The nature of these relationships vary as women traverse the menopause and ovarian hormone production ceases. This review describes these cross-cutting themes and their possible meaning for the health of the mid-life woman.
