Fish intake and the risk of incident heart failure: the Women's Health Initiative.

ABSTRACT: Whether fish or the fatty acids they contain are independently associated with risk for incident heart failure (HF) among postmenopausal women is unclear.The baseline Women's Health Initiative Observational Study cohort consisted of 93 676 women ages 50 to 79 years of diverse ethnicity and background, of which 84 493 were eligible for analyses. Intakes of baked/broiled fish, fried fish, and omega-3 fatty acid (eicosapentaenoic acid+docosahexaenoic acid, ?-linolenic acid), and trans-fatty acid were determined from the Women's Health Initiative food frequency questionnaire. Baked/broiled fish consumption was divided into 5 frequency categories: <1/mo (referent), 1 to 3/mo, 1 to 2/wk, 3 to 4/wk, ?5/wk. Fried fish intake was grouped into 3 frequency categories: <1/mo (referent), 1-3/mo, and ?1/wk. Associations between fish or fatty acid intake and incident HF were determined using Cox models adjusting for HF risk factors and dietary factors. Baked/broiled fish consumption (?5 servings/wk at baseline) was associated with a hazard ratio of 0.70 (95% confidence interval, 0.51 to 0.95) for incident HF. In contrast, fried fish consumption (?1 serving/wk at baseline) was associated with a hazard ratio of 1.48 (95% confidence interval, 1.19 to 1.84) for incident HF. No significant associations were found between eicosapentaenoic acid+docosahexaenoic acid, ?-linolenic acid, or trans-fatty acid intake and incident HF.Increased baked/broiled fish intake may lower HF risk, whereas increased fried fish intake may increase HF risk in postmenopausal women.

Project description:ImportanceSome prior evidence suggests that adverse pregnancy outcomes (APOs) may be associated with heart failure (HF). Identifying unique factors associated with the risk of HF and studying HF subtypes are important next steps.ObjectiveTo investigate the association of APOs with incident HF overall and stratified by HF subtype (preserved vs reduced ejection fraction) among postmenopausal women in the Women's Health Initiative (WHI).Design, setting, and participantsIn 2017, an APO history survey was administered in the WHI study, a large multiethnic cohort of postmenopausal women. The associations of 5 APOs (gestational diabetes, hypertensive disorders of pregnancy [HDP], low birth weight, high birth weight, and preterm delivery) with incident adjudicated HF were analyzed. In this cohort study, the association of each APO with HF was assessed using logistic regression models and with HF subtypes using multinomial regression, adjusting for age, sociodemographic characteristics, smoking, randomization status, reproductive history, and other APOs. Data analysis was performed from January 2020 to September 2021.ExposuresAPOs (gestational diabetes, HDP, low birth weight, high birth weight, and preterm delivery).Main outcomes and measuresAll confirmed cases of women hospitalized with HF and HF subtype were adjudicated by trained physicians using standardized methods.ResultsOf 10 292 women (median [IQR] age, 60 [55-64] years), 3185 (31.0%) reported 1 or more APO and 336 (3.3%) had a diagnosis of HF. Women with a history of any APO had a higher prevalence of hypertension, diabetes, coronary heart disease, or smoking. Of the APOs studied, only HDP was significantly associated with HF with a fully adjusted odds ratio (OR) of 1.75 (95% CI, 1.22-2.50), and with HF with preserved ejection fraction in fully adjusted models (OR, 2.06; 95% CI, 1.29-3.27). In mediation analyses, hypertension explained 24% (95% CI, 12%-73%), coronary heart disease 23% (95% CI, 11%-68%), and body mass index 20% (95% CI, 10%-64%) of the association between HDP and HF.Conclusions and relevanceIn this large cohort of postmenopausal women, HDP was independently associated with incident HF, particularly HF with preserved ejection fraction, and this association was mediated by subsequent hypertension, coronary heart disease, and obesity. These findings suggest that monitoring and modifying these factors early in women presenting with HDP may be associated with reduced long-term risk of HF.

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.

Project description:Nutrient-related anemia among postmenopausal women is preventable; recent data on prevalence are limited.To investigate the association between nutrient intakes and anemia prevalence, in relation to both incidence and persistence, in a longitudinal sample of postmenopausal women. We hypothesized that anemia prevalence, incidence, and persistence would be greater among women reporting lower intake of vitamin B-12, folate, and iron.Prospective cohort analysis.The observational cohort of the Women's Health Initiative, including 93,676 postmenopausal women, aged 50 to 79 years, who were recruited across the United States at 40 clinical study sites. Women were enrolled between 1993 and 1998; data collection for these analyses continued through 2000.Anemia was defined as a blood hemoglobin concentration of <12.0 g/dL (120.0 g/L). Persistent anemia was defined as anemia present at each measurement time point. Diet was assessed by food frequency questionnaire for iron, folate, B-12, red meat, and cold breakfast cereal; inadequacies were based on dietary reference intakes for women older than age 50 years.Descriptive statistics (mean ± standard deviation) were used to characterize the population demographics, anemia rates, and diet. Unconditional logistic regression was used to investigate associations between diet and incident and persistent anemia. Associations are presented as odds ratio and 95% confidence intervals.Anemia was identified in 3,979 (5.5%) of the cohort. Inadequate intakes of multiple anemia-associated nutrients were less frequent in non-Hispanic whites (7.4%) than other race/ethnic groups (inadequacies demonstrated in 14.6% to 16.3% of the sample). Age, body mass index, and smoking were associated with anemia. Women with anemia reported lower intakes of energy, protein, folate, vitamin B-12, iron, vitamin C, and red meat. Multiple (more than a single nutrient) dietary deficiencies were associated with a 21% greater risk of persistent anemia (odds ratio 1.21, 95% confidence interval 1.05 to 1.41) and three deficiencies resulted in a 44% increase in risk for persistent anemia (odds ratio 1.44, 95% confidence interval 1.20 to 1.73).Inadequate nutrient intake, a modifiable condition, is associated with greater risk for anemia in postmenopausal women participating in the Observational Study of the Women's Health Initiative. Efforts to identify and update incidence estimates for anemia-associated nutrient deficiencies in aging women should be undertaken.
