Prevalence of the cardiovascular health status in adults: A systematic review and meta-analysis

The American Heart Association has outlined seven cardiovascular health (CVH) metrics, including smoking, body mass index, physical activity, dietary pattern, total cholesterol, and fasting plasma glucose, to define and monitor CVH status. Our study was to evaluate the global CVH in adults.

We searched PubMed, Embase, Cochrane Central Register of Controlled Trials, and reference lists of relevant articles for studies published between 1 January 2010 and 30 June 2018. Included studies should report the proportions of ideal status for the seven CVH metrics and/or provide the prevalence of overall poor (having 0-2 ideal metrics) or ideal (having 5-7 ideal metrics) CVH status in adults. 88 articles were identified: 75 for the prevalence of ideal CVH metrics, 58 for the proportion of overall poor CVH status, and 55 for the proportion of overall ideal CVH status. Smoking had the highest prevalence of ideal status (69.1%) while dietary pattern has the lowest (12.1%). 32.2% and 19.6% of participants had overall poor and ideal CVH, respectively. Females and young adults had better CVH status when compared to males and older adults. There existed regional variations in ideal CVH metrics and overall CVH status. The overall CVH status had improved over study time.

The prevalence of ideal status was low for some metrics, such as dietary pattern, and the overall CVH status was still unsatisfactory. We should continue to measure the CVH status and carry out lifestyle interventions to improve the CVH status in the whole population.
