Abstract 13062: Life's Simple 7 in 2003–2007 and Mortality in Blacks and Whites: The REasons for Geographic and Racial Differences in Stroke (REGARDS) Cohort
Background: The AHA 2020 goal aims to improve cardiovascular health, the latter being defined by a new metric dividing people into poor, intermediate and ideal categories for 7 health factors (blood pressure, cholesterol, glucose, BMI, smoking, physical activity, diet); Life's Simple 7. We evaluated the distribution and association of these factors with mortality in a national US population sample.
Methods: We studied 17,820 REGARDS participants; black and white men and women aged 45–98 from across the US, enrolled in 2003–7, when extensive risk factor data were measured in participants' homes and by questionnaires. We calculated baseline prevalence of ideal levels of each of the 7 factors and assessed mortality by number of ideal factors. Over 4.4 years follow up, 988 died.
Results: Two (0.01%) participants had 7 of 7 ideal health factors. The percent with 6, 5, 4, 3, 2, 1 or 0 ideal factors were 1.1%, 5.8%, 16.0%, 27.5%, 29.9%, 16.3% and 3.4%. Participants with 5–7 ideal factors were more likely to be <65 (7.5 vs 6.3% in >65), female (7.6 vs 6.1% in males), and white (8.6 vs 3.5% in blacks; all p<0.05). Fasting glucose had the highest prevalence, and diet score had the lowest prevalence of ideal status (66.9% and 0.43%, respectively). The figure shows mortality by number of ideal factors. Adjusting for age, race, sex, income and education, there was a 14% lower mortality risk for each higher number of ideal health factors (95% CI 0.10-0.19). Compared to those with 0 ideal factors, mortality for persons with 5–7 ideal factors was 55% lower (95% CI 0.31-0.70). Absolute 5-year mortality rate was 9% in those with 0 ideal factors in contrast to 3.3% with 6–7 ideal factors.
Conclusion: Less than 25% of black and white Americans age 45–98 have 4 or more of Life's Simple 7 factors at idea levels. Those with higher numbers of ideal health factors had lower mortality. Findings provide information to inform interventions to reduce mortality rates and achieve the AHA 2020 Impact Goal.
