Abstract P370: Cardiovascular Health Metrics, Lifetime Risks of Cardiovascular Disease and Chronic Disease Mortality, and Life Expectancy in Men and Women

Abstract

Whether cardiovascular health metrics relates to lifetime risks of cardiovascular disease (CVD) and chronic disease mortality and life expectancy in U.S. population remains less explored. PURPOSE: We investigated the combined impact of 7 ideal cardiovascular health metrics on lifetime risks of CVD and chronic disease mortality and life expectancy in US men and women at 30 years of age. METHODS: Lifetime risks of CVD and chronic disease mortality to 80 years of age were estimated for men and women, with death free of chronic diseases as a competing event. We followed 11,341 men and women, aged 30 to 80 years, who participated in the Third National Health and Nutrition Examination Survey. All participants completed baseline lifestyle factors and lifestyle behavior questionnaires. The 7 ideal cardiovascular health metrics was defined as physically active, never smoking, a healthy diet, waist girth (<102/88 cm), untreated blood pressure (<120/80 mmHg), untreated total cholesterol (<200 mg/dL), and untreated fasting glucose (<100 mg/dL) defined by the American Heart Association Strategic Committee. They were further categorized as having 0, 1, 2, 3, 4, 5, 6 or 7 combined cardiovascular health metrics. RESULTS: During an average of 13.7 years of follow-up (155,726 person-years), there were a total of 1834 chronic disease deaths (945 CVD, 579 cancer, 217 respiratory disease, 93 diabetes mellitus). The lifetime risks of chronic disease mortality (at 30 years of age) across 0, 1, 2, 3, 4, 5, and 6 or 7 ideal health metrics were (95% CI) 46.2% (41.6, 50.7), 40.3% (36.9, 43.8), 33.1% (30, 36.1), 27.2% (23.9, 30.5), 25.8% (21, 30.5), 24.8% (16.8, 32.9), and 12.7% (1.2, 24.1), respectively. Men and women who had adopted increasing number ideal health metrics had a substantially lower lifetime risk of chronic disease mortality. The lifetime risks of CVD mortality across 7 ideal health metrics showed trends similar to chronic disease mortality. After adjustment for multiple risk factors, men and women with all 6 or 7 combined ideal health metrics had a 75% (95% CI: 51% to 88%) lower risk of chronic disease mortality and 93% (95% CI: 53% to 99%) lower risk of CVD mortality, respectively, when compared with men and women with zero ideal health metrics. Men and women with 0 compared with 6 or 7 combined ideal health metrics had a shorter life expectancy by 16 years (95% CI: 13 to 19.1 years). Approximately 63% (95% CI: 26% to 82%) of chronic disease deaths might have been avoided if men and women had maintained all 6 or 7 combined health factors and healthy lifestyle behaviors. CONCLUSION: Maintaining an ideal cardiovascular health metrics is associated with lower lifetime risks of CVD and chronic disease mortality in men and women.
