Abstract:
Objective To explore the association between body mass index(BMI) and ten-year accumulative risk of hypertension. Methods A prospective study of relationship between blood pressure and other traditional risk factors was carried out in a cohort with 2115 people aged 35-64 years old involved, in 1992 and 2002. The association between baseline BMI level and a ten-year accumulative risk of hypertension was analyzed. Results The ten-year accumulative incidence rate of hypertension was 34.8%, and increased with the elevated baseline BMI level in both genders (P<0.001). Similar changing trends were observed in both age groups of 45-54 year and 55-64 year olds (P<0.05). Multivariable OR (95%CI) of accumulative incident hypertension in the highest BMI tertile(≥128 kg/m2) was 3.569 higher (2.559 to 4.977) when compared to the lowest (<24 kg/m2). The ten-year accumulative risk of hypertension increased 17.5% with elevation of baseline BMI level by 1 kg/m2. The ten-year accumulative incidence rate of hypertension was 22.0% in the subjects with normal BMI and 56.3% in those with obesity, both in 1992 and 2002. Conclusion BMI appeared to be an independent risk factor for hypertension, and the risk of incident hypertension increased with elevated BMI level.
