Only 1 in 5 people in the US has optimal heart health

New Life’s Essential 8 score reveals concerning data, reports American Heart Association

About 80% of people in the US have low to moderate cardiovascular health based on the American Heart Association’s new Life’s Essential 8 checklist, according to a new study published in Circulation, the Association’s flagship, peer-reviewed journal [1].

Life’s Essential 8, also published in Circulation, details the Association’s updated guidance to measure cardiovascular health, adding healthy sleep as essential for ideal heart and brain health.

Longevity.Technology: The Life’s Essential 8 metrics are incorporated into the AHA’s My Life Check tool; the metrics determine a cardiovascular health score based on eight essential components for ideal heart and brain health: diet, physical activity, nicotine exposure, sleep duration, body mass index, blood lipids, blood glucose and blood pressure. It is an updated algorithm from the scientifically proven Life’s Simple 7, which did not include sleep heath, but which research is increasingly showing is key for lifespan and healthspan.

Life’s Essential 8 also has updated metrics, making it more sensitive to differences among groups of people. In adults, overall cardiovascular health is calculated for each individual by summing the scores for each of the 8 metrics together and dividing the total by 8, to provide a Life’s Essential 8 score ranging from 0-100. Thus, the highest or healthiest cardiovascular health score possible is 100. Overall scores below 50 indicate “low” cardiovascular health, 50-79 is considered “moderate” and scores of 80 and above indicate “high” cardiovascular health.

According to this first study using Life’s Essential 8 as the measure for cardiovascular health, among more than 23,400 US adults and children free of cardiovascular disease, the overall cardiovascular health of the US population is well below ideal, with 80% of adults scoring at a low or moderate level. Researchers evaluated health information from the US National Health and Nutrition Examination surveys in 2013-2018 that included more than 13,500 adults (ages 20-79 years) and nearly 9,900 children (ages 2 to 19 years).

Results of the analysis

  • The average cardiovascular health score based on Life’s Essential 8 was 64.7 for US adults and 65.5 for US children. The children’s average took into consideration age-based modifications for metrics in diet, physical activity and BMI for children ages 2 to 19 years.
  • Only 0.45% of adults scored 100 on Life’s Essential 8.
  • 19.6% of US adults had high cardiovascular health; 62.5% moderate; and 17.9% low.
  • Adult women had higher average cardiovascular health scores, of 67, compared with men, with a score of 62.5.
  • In general, US adults scored lowest in the areas of diet, physical activity and BMI.
  • Cardiovascular health scores were generally lower at older ages.
  • Individuals who identify as Non-Hispanic Asian Americans had a higher average cardiovascular health score than other racial/ethnic groups. Non-Hispanic White individuals had the second highest average cardiovascular health score, followed, in order, by Hispanic (other than Mexican), Mexican, and Non-Hispanic Black individuals.
  • Children’s diet scores were low, at an average of 40.6.
  • Adult sociodemographic groups varied notably in cardiovascular health scores for diet, nicotine exposure, blood glucose and blood pressure.

“These data represent the first look at the cardiovascular health of the US population using the AHA’s new Life’s Essential 8 scoring algorithm,” said Donald M Lloyd-Jones, MD, ScM, FAHA, who led the study and is president of the American Heart Association, and chair of the department of preventive medicine at Northwestern University’s Feinberg School of Medicine in Chicago.

“Overall, the cardiovascular health of the US population is suboptimal, and we see important differences across age and sociodemographic groups. Analyses like this can help policy makers, communities, clinicians and the public to understand the opportunities to intervene to improve and maintain optimal cardiovascular health across the life course [2].”
