Prevalence and incident prehypertension and hypertension in postmenopausal Hispanic women: results from the Women's Health Initiative.

ABSTRACT: BACKGROUND:There is a paucity of research on prehypertension and incident hypertension among postmenopausal Hispanic women. The overall objective is to determine the multiple risk factors associated with the prevalence of hypertension status at baseline and incident hypertension at year 3 in postmenopausal Hispanic women. METHODS:For the analyses in this paper, we included a total of 4,680 Hispanic women who participated in the Women's Health Initiative (WHI), a randomized clinical trial and observational study, at baseline (1994-1998) and at third-year follow-up and for whom blood pressure was measured at year 3 (n = 3,848). Multivariable logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) of hypertension status, defined as systolic blood pressure ?140 mm Hg and/or diastolic blood pressure ?90 mm Hg, to assess the odds of incident hypertension at year 3 of follow-up in association with the factors included in the baseline models. RESULTS:At year 3 of follow-up, 27.3% of Hispanic women who were normotensive at baseline had progressed to prehypertension, and 9.0% had become hypertensive. Among the prehypertensive participants at baseline, 30.4% had progressed to hypertension. Compared with normotensive Hispanic women, hypertensive participants had a higher number of cardiovascular risk factors: body mass index ?30 kg/m(2) (OR = 3.76; 95% CI = 3.01-4.71), a family history of diabetes, stroke, and/or myocardial infarction (OR = 1.12; 95% CI 1.03-1.23), treated hypercholesterolemia (OR = 1.57; 95% CI = 1.23-1.99), treated diabetes (OR = 2.04; 95% CI = 1.40-2.97), and a history of cardiovascular disease (OR = 2.04; 95% CI = 1.58-2.64). CONCLUSIONS:Hispanic women seem to experience an increased risk of incident hypertension in later adulthood. On a practical level, recommendations for preventive care and population-wide adoption of health behaviors, such as community-focused campaigns to engage in physical activity, may contribute to reductions in hypertension risk factors.

Project description:BackgroundDepression and depressive symptoms are risk factors for hypertension (HTN) and cardiovascular disease (CVD). Hispanic women have higher rates of depressive symptoms compared to other racial/ethnic groups yet few studies have investigated its association with incident prehypertension and hypertension among postmenopausal Hispanic women. This study aims to assess if an association exists between baseline depression and incident hypertension at 3 years follow-up among postmenopausal Hispanic women.MethodsProspective cohort study, Women's Health Initiative (WHI), included 4,680 Hispanic women who participated in the observational and clinical trial studies at baseline and at third-year follow-up. Baseline current depressive symptoms and past depression history were measured as well as important correlates of depression-social support, optimism, life events and caregiving. Multinomial logistic regression was used to estimate prevalent and incident prehypertension and hypertension in relation to depressive symptoms.ResultsPrevalence of current baseline depression ranged from 26% to 28% by hypertension category and education moderated these rates. In age-adjusted models, women with depression were more likely to be hypertensive (OR = 1.25; 95% CI 1.04-1.51), although results were attenuated when adjusting for covariates. Depression at baseline in normotensive Hispanic women was associated with incident hypertension at year 3 follow-up (OR = 1.74; 95% CI 1.10-2.74) after adjustment for insurance and behavioral factors. However, further adjustment for clinical covariates attenuated the association. Analyses of psychosocial variables correlated with depression but did not alter findings. Low rates of antidepressant medication usage were also reported.ConclusionsIn the largest longitudinal study to date of older Hispanic women which included physiologic, behavioral and psychosocial moderators of depression, there was no association between baseline depressive symptoms and prevalent nor incident pre-hypertension and hypertension. We found low rates of antidepressant medication usage among Hispanic women suggesting a possible point for clinical intervention.Trial registrationClinicaltrials.gov NCT00000611.

Project description:IMPORTANCE:Considerable efforts have been undertaken to relate single nutrients to bone health. To this point, results are inconsistent. Suboptimal single nutrient intake does not occur in isolation but rather reflects a poor diet quality. OBJECTIVE:To assess the association between adherence to a diet quality index constructed on the basis of dietary recommendations or existing healthy dietary patterns and fractures in postmenopausal women. DESIGN, SETTING, AND PARTICIPANTS:Post hoc analysis was conducted of longitudinal data from 40 clinical centers throughout the United States included in the Women's Health Initiative (WHI) observational study. Participants in the prospective cohort included 93?676 women who were eligible for the WHI if they were aged 50 to 79 years. Recruitment was conducted from October 1, 1993, to December 31, 1998, with the study ending August 29, 2014. The WHI food frequency questionnaire was used to derive nutrient and food intake at baseline. Diet quality and adherence were assessed by scores on the alternate Mediterranean Diet (aMED), a 9-category measure of adherence to a Mediterranean dietary pattern; the Healthy Eating Index 2010 (HEI-2010), a 100-point measure of 12 food components; the 11-item Alternate Healthy Eating Index 2010 (AHEI-2010); or the 8-component Dietary Approaches to Stop Hypertension (DASH) diet score. MAIN OUTCOMES AND MEASURES:Outcome measures included incident total and hip fractures. Hazard ratios (HRs) by quintiles of dietary index scores were estimated using Cox proportional hazards regression analyses. RESULTS:Of the 93?676 participants, 90?014 were included in the analysis (mean [SD] age, 63.6 [7.4]) years. During a median follow-up time of 15.9 years, there were 2121 cases of hip fractures and 28?718 cases of total fractures. Women scoring in the highest quintile (Q5) of the aMED index had a lower risk for hip fractures (HR, 0.80; 95% CI, 0.66-0.97), with an absolute risk reduction of 0.29% and a number needed to treat of 342 (95% CI, 249-502). No association between the aMED score and total fractures was observed (Q5 HR, 1.01; 95% CI, 0.95-1.07). Higher HEI-2010 or DASH scores tended to be inversely related to hip fracture risk, but the results were nonsignificant (Q5 HR, 0.87; 95% CI, 0.75-1.02; and Q5 HR, 0.89; 95% CI, 0.75-1.06, respectively). The AHEI-2010 score was associated with neither hip nor total fractures. CONCLUSIONS AND RELEVANCE:Higher adherence to a Mediterranean diet is associated with a lower risk for hip fractures. These results support that a healthy dietary pattern may play a role in maintaining bone health in postmenopausal women.

Project description:BackgroundThe differences in the incidence of heart failure by race/ethnicity and the potential mechanisms for these differences are largely unexplored in women.Methods and resultsA total of 156 143 postmenopausal women free of self-reported heart failure enrolled from 1993 to 1998 at 40 clinical centers throughout the United States as part of the Women's Health Initiative and were followed up until 2005, for an average of 7.8 years, for incident hospitalized heart failure. Incident rates, hazard ratios (HRs), and 95% confidence intervals were determined by use of the Cox proportional hazard model comparing racial/ethnic groups, and population-attributable risk percentages were calculated for each racial/ethnic group. Blacks had the highest age-adjusted incidence of heart failure (380 in 100 000 person-years), followed by whites (274), Hispanics (193), and Asian/Pacific Islanders (103). The excess risk in blacks compared with whites (age-adjusted HR=1.45) was significantly attenuated by adjustment for household income (HR=0.97) and diabetes mellitus (HR=0.89), but the lower risk in Hispanics (age-adjusted HR=0.72) and Asian/Pacific Islanders (age-adjusted HR=0.44) remained despite adjustment for traditional risk factors, socioeconomic status, lifestyle, and access-to-care variables. The effect of adjustment for interim coronary heart disease on nonwhite versus white HRs for heart failure differed by race/ethnic group.ConclusionsAsian/Pacific Islander and Hispanic women have a lower incidence of heart failure and black women have higher rates of heart failure compared with white women. The excess risk of incident heart failure in black women is explained largely by adjustment for lower household incomes and diabetes mellitus in black women, whereas the lower rates of heart failure in Asian/Pacific Islanders and Hispanics are largely unexplained by the risk factors measured in this study.Clinical trial registrationURL: http://www.clinicaltrials.gov.
