Ideal Cardiovascular Health Metrics in Couples: A Community-Based Study

Background-Determination of the correlation of ideal cardiovascular health variables among spousal or cohabitating partners may guide the development of couple-based interventions to reduce cardiovascular disease risk. Method and Results-We used data from the HeartSCORE (Heart Strategies Concentrating on Risk Evaluation) study. Ideal cardiovascular health, defined by the American Heart Association, comprises nonsmoking, body mass index <25 kg/m(2), physical activity at goal, diet consistent with guidelines, untreated total cholesterol <200 mg/dL, untreated blood pressure <120/ 80 mm Hg, and untreated fasting glucose <100 mg/dL. McNemar test and logistic regression were used to assess concordance patterns in these variables among partners (ie, concordance in achieving ideal factor status, concordance in not achieving ideal factor status, or discordance-only one partner achieving ideal factor status). Overall, there was a low prevalence of ideal cardiovascular health among the 231 couples studied (median age 61 years, 78% white). The highest concordances in achieving ideal factor status were for nonsmoking (26.1%), ideal fruit and vegetable consumption (23.9%), and ideal fasting blood glucose (35.6%). The strongest odds of intracouple concordance were for smoking (odds ratio, 3.6; 95% confidence interval, 1.9-6.5), fruit and vegetable consumption (odds ratio, 4.8; 95% confidence interval, 2.5-9.3) and blood pressure (odds ratio, 3.0; 95% confidence interval, 1.2-7.9). A participant had 3-fold higher odds of attaining >= 3 ideal cardiovascular health variables if he or she had a partner who attained >= 3 components (odds ratio 3.0; 95% confidence interval, 1.6-5.6). Conclusions-lntracouple concordance of ideal cardiovascular health variables supports the development and testing of couple-based interventions to promote cardiovascular health. Fruit and vegetable consumption and smoking may be particularly good intervention targets.
