Strawberry intake, lipids, C-reactive protein, and the risk of cardiovascular disease in women.

Abstract：

OBJECTIVE:There is indirect evidence suggesting that strawberries, containing several key nutrients, may be associated with the risk of cardiovascular disease (CVD). In the Women's Health Study, we examined strawberry intake for both its prospective association with CVD risk in 38,176 women and its cross-sectional association with lipids and C-reactive protein (CRP) in a subset of 26,966 women. METHODS:Strawberry intake was assessed from a baseline semiquantitative food frequency questionnaire, along with other self-reported lifestyle, clinical and dietary factors. Participants returned baseline bloods which were assayed for lipids and CRP. We computed the relative risks (RRs) for total CVD (1,004 cases) (including confirmed myocardial infarction, stroke, revascularization, and cardiovascular death) occurring during 10.9 years of follow-up. RESULTS:At baseline, 25.6%, 41.9%, 24.8%, and 7.7% of women reported corresponding strawberry intake of none, 1-3 servings/month, 1 serving/week, and > or =2 servings/week. For total CVD, the multivariate RRs (95% confidence intervals) for increasing categories of strawberry intake were 1.00 (ref), 1.01 (0.85-1.19), 0.95 (0.77-1.17), and 1.27 (0.94-1.72) (P, trend = 0.06). We found a similar lack of an association for individual cardiovascular endpoints and comparing mean levels of lipids and CRP by category of strawberry intake. However, women consuming > or =2 servings/week versus none had a borderline significant, multivariate 14% lower likelihood of an elevated CRP of > or =3 mg/L. CONCLUSIONS:Strawberry intake was unassociated with the risk of incident CVD, lipids, or CRP in middle-aged and older women, though higher strawberry intake may slightly reduce the likelihood of having elevated CRP levels. Additional epidemiologic data are needed to clarify any role of strawberries in CVD prevention.
