Lifestyle and Risk of Hypertension: Follow-Up of a Young Pre-Hypertensive Cohort
1. Center of Clinical Pharmacology, the Third Xiangya Hospital, Central South University, Changsha, China
Objectives: To determine whether healthy lifestyle decreases the risk of developing hypertension in pre-hypertensive patients.
Study design: A longitudinal study.
Setting & participants: Randomly selected pre-hypertensive young adults 20-45 years old without any vascular disease such as stroke or diabetes.
Predictors: Four lifestyle factors (a body mass index [BMI] of 18.5-24.9 kg/m2, regular physical activity, no alcohol use and 6-8 h of sleep per day), individually and in combination.
Outcomes: Hypertension was defined as a systolic blood pressure (SBP) ≥ 140 mmHg, or a diastolic BP (DBP) ≥ 90 mmHg or self-reported hypertension.
Measurements: Multivariate adjusted Cox proportional hazards.
Results: During a median follow-up of 4.7 years, 1009 patients were enrolled in our study, and 182 patients developed hypertension. Compared with a BMI of 18.5-24.9 kg/m2, a BMI of 25-30 kg/m2 and a BMI of >30 kg/m2 were associated with an increased risk of hypertension occurrence (hazard ratio [HR], 1.83; 95% confidence interval [CI], 1.19-2.84 and HR, 2.62; 95% CI, 1.01-6.80, respectively). Compared with sleep duration of >8 h/day, 6-8 h/day of sleep was associated with a lower risk of hypertension occurrence (HR, 0.40; 95% CI, 0.18-0.86). There were no statistically significant associations between physical activity or alcohol use and hypertension occurrence (P>0.05).
Limitation: All lifestyle factors were measured only once.
Conclusion: Healthy BMI (18.5-24.9 kg/m2) and sleep duration (6-8 h/day) were associated with a lower risk of the occurrence of hypertension in pre-hypertension patients.
