Vital Signs: Prevalence of Key Cardiovascular Disease Risk Factors for Million Hearts 2022 - United States, 2011-2016.

INTRODUCTION

Despite decades-long reductions in cardiovascular disease (CVD) mortality, CVD mortality rates have recently plateaued and even increased in some subgroups, and the prevalence of CVD risk factors remains high. Million Hearts 2022, a 5-year initiative, was launched in 2017 to address this burden. This report establishes a baseline for the CVD risk factors targeted for reduction by the initiative during 2017-2021 and highlights recent changes over time.

METHODS

Risk factor prevalence among U.S. adults was assessed using data from the National Health and Nutrition Examination Survey, National Survey on Drug Use and Health, and National Health Interview Survey. Multivariate analyses were performed to assess differences in prevalence during 2011-2012 and the most recent cycle of available data, and across subgroups.

RESULTS

During 2013-2014, the prevalences of aspirin use for primary and secondary CVD prevention were 27.4% and 74.9%, respectively, and of statin use for cholesterol management was 54.5%. During 2015-2016, the average daily sodium intake was 3,535 mg/day and the prevalences of blood pressure control, combustible tobacco use, and physical inactivity were 48.5%, 22.3%, and 29.1%, respectively. Compared with 2011-2012, significant decreases occurred in the prevalences of combustible tobacco use and physical inactivity; however, a decrease also occurred for aspirin use for primary or secondary prevention. Disparities in risk factor prevalences were observed across age groups, genders, and racial/ethnic groups.

CONCLUSIONS AND IMPLICATIONS FOR PUBLIC HEALTH PRACTICE

Millions of Americans have CVD risk factors that place them at increased risk for having a cardiovascular event, despite the existence of proven strategies for preventing or managing CVD risk factors. A concerted effort to implement these strategies will be needed to prevent one million acute cardiovascular events during the 5-year initiative.
