Association of Cardiovascular Health Metrics With Risk of Transition to Hypertension in Non-Hypertensive Young Adults.

Background: The risk of developing hypertension in young adults and its relationship to modifiable lifestyle factors are unclear. We aimed to examine the association of cardiovascular health (CVH) metrics with the risk of hypertension.

Methods: We analyzed 66,876 participants aged 20-39 years, with available blood pressure (BP) data for 5 consecutive years, who had normal or elevated BP at the initial health check-up, enrolled in the JMDC Claims Database. Ideal CVH metrics included nonsmoking, body mass index <25 kg/m2, physical activity at goal, optimal dietary habits, untreated fasting glucose <100 mg/dL, and untreated total cholesterol <200 mg/dL. The primary endpoint was defined as stage 1 or stage 2 hypertension. We defined normal BP, elevated BP, stage 1 hypertension, and stage 2 hypertension according to the 2017 American College of Cardiology/American Heart Association (ACC/AHA) BP guideline.

Results: The median age was 35 years, and 62% were men. Number of non-ideal CVH metrics was associated with an increasing risk for the development of stage 1 and stage 2 hypertension. Non-ideal body mass index was most strongly associated with a risk for hypertension. This association was more pronounced in women. An annual increase in the number of non-ideal CVH metrics was associated with an elevated risk for the hypertension development.

Conclusions: CVH metrics can stratify the risk for hypertension in non-hypertensive adults aged 20-39 years. These findings have important public health implications for the screening and prevention of hypertension. Improving CVH metrics may prevent the risk of developing hypertension in young adults.
