Optimal Lifestyle Components in Young Adulthood Are Associated With Maintaining the Ideal Cardiovascular Health Profile Into Middle Age

Abstract

BackgroundMiddle‐aged adults with ideal blood pressure, cholesterol, and glucose levels exhibit substantially lower cardiovascular mortality than those with unfavorable levels. Four healthy lifestyle components—optimal body weight, diet, physical activity, and not smoking—are recommended for cardiovascular health (CVH). This study quantified associations between combinations of healthy lifestyle components measured in young adulthood and loss of the ideal CVH profile into middle age.Methods and ResultsAnalyses included 2164 young adults in the Coronary Artery Risk Development in Young Adults study with the ideal CVH profile (defined as untreated blood pressure <120/80 mm Hg, total cholesterol <200 mg/dL, fasting blood glucose <100 mg/dL, and absence of cardiovascular disease) at baseline. Cox proportional hazards regression models estimated hazard ratios for loss of the ideal CVH profile over 25 years according to 4 individual and 16 combinations of optimal healthy lifestyle components measured in young adulthood: body mass index, physical activity, nonsmoking status, and diet quality. Models were adjusted for age, sex, race, education, study center, and baseline blood pressure, cholesterol, and glucose. Eighty percent (n=1737) of participants lost the ideal CVH profile by middle age; loss was greatest for young adults with no optimal healthy lifestyle components at baseline. Relative to young adults with no optimal healthy lifestyle components, those with all 4 were less likely to lose the ideal CVH profile (hazard ratio 0.59, 95% CI 0.44–0.80). Combinations that included optimal body mass index and nonsmoking status were each associated with lower risk.ConclusionsOptimal body mass index and not smoking in young adulthood were protective against loss of the ideal CVH profile through middle age. Importance of diet and physical activity may be included through their effects on healthy weight.

Self-rated health as an indicator of ideal cardiovascular health among working-aged women

“…Normal BMI is the most potent indicator of good self-reported well-being and nonsmokers rate their health twice as good as current smokers. These two health behaviors are also the most protective metrics against a loss of ideal CVH profile through middle age [ 33 ]. According to the present study, ideal plasma cholesterol, glucose or blood pressure levels do not predict good SRH.…”

Adolescent Perceptions of Cholesterol Screening Results: “Young Invincibles” or Developing Adults?

“…This is consistent with prior findings in the tobacco literature that suggests young people have a poor understanding of the relevance of cumulative risk of an exposure over the lifetime. 28 Given data demonstrating the importance of early young adult factors for later life cardiovascular health, 29 this lower motivation to address health threats many years in the future represents an opportunity for targeted health promotion efforts. In particular, these findings are suggestive of the promise for health counseling, within a motivational interviewing framework, in delivering results of cholesterol screening with AYAs; further research examining the effectiveness of such approaches is warranted.…”

Empirically derived dietary-lifestyle patterns and cardiometabolic health in young men: a review

“…Lifestyle risk profiles in young men, as modifiable factors, have been rarely studied in the context of cardiometabolic health. This is of particular concern since behaviours acquired in young adulthood may trigger pathophysiological processes with immediate or delayed health consequences (5,6) .…”
