Abstract

OBJECTIVE:

To evaluate the influence of overweight/obesity on the incidence of hypertension among adults in China.

METHODS:

The subjects of this prospective study were 13 739 Chinese adults aged 35-74 years recruited at the baseline surveys of China Multicenter Collaborative Study of Cardiovascular Disease Epidemiology and International Collaborative Study of Cardiovascular Disease in Asian. Baseline surveys were conducted in 1998 and during 2000-2001, respectively, and the follow-up was conducted during 2007-2008. According to the body mass index, the subjects were divided into four groups: underweight group(<18.5 kg/m(2)), normal weight group(18.5-23.9 kg/m(2)), overweight group(24.0-27.9 kg/m(2))and obesity group(≥28.0 kg/m(2)). Age-standardized cumulative incidence of hypertension was calculated for each group, respectively. The relative risks(RRs)and 95% confidence intervals(CIs)for the incidence of hypertension of underweight, overweight and obesity groups were estimated by using generalized linear regression model with normal weight group as reference.

RESULTS:

During 8.1 years of follow-up, 4 271 hypertension cases were detected(2 012 in men and 2 259 in women). Age-standardized cumulative incidence of hypertension for the underweight, normal weight, overweight and obesity groups were 20.3%, 30.9%, 43.6% and 50.8% in men, respectively; and 22.9%, 30.4%, 41.1% and 50.8% in women, respectively. Compared with the normal weight group, multivariate-adjusted RR(95% CI)for the incidence of hypertension in underweight, overweight and obesity groups were 0.78(0.64-0.95), 1.22(1.13-1.30)and 1.28(1.16-1.42)in men, respectively; and 0.89(0.77-1.03), 1.16(1.09-1.23)and 1.28(1.18-1.38)in women, respectively. The overweight and obese subjects had higher risk for the incidence of hypertension, with the population attributable risk proportion of 7.4% in men and 8.8% in women, respectively.

CONCLUSION:

Overweight or obese people are at an increased risk of developing hypertension, thus prevention and control of overweight/obesity are needed to reduce hypertension incidence among adults in China.
