Body mass index and hypertension among Chinese governmental and institutional employees in Beijing

摘要

Body mass index (BMI) and hypertension have been found to be associated in most studies of diverse populations; however, little information is available on whether the positive relationship is consistent among individuals at work sites. A work site-based screening was performed in 30 682 employees with a mean age of 40.3 years. In crude models, higher BMI quartiles above the lowest quartiles (BMI 20.6 kg/m 2) were associated with progressively higher odds ratio (OR) of hypertension with an OR of 2.80 (95% confidence interval [CI]: 2.67-2.93) for the top quartile (BMI 24.6 kg/m 2). Similar trends were found in fully adjusted models. Moreover, a 1-standard deviation (SD) increase in BMI was associated with a 42% significantly higher (95% CI 38-46) risk of hypertension after adjusting for other factors. Concordant relationships were revealed in all evaluated subgroups, even among those without traditional cardiovascular risk factors.
