title: Relationship between body mass index changes and blood pressure changes from childhood to adulthood in a general Chinese population: a 26 year cohort follow-up study.
abstract: The aim of this study was to estimate the relationship between body mass index (BMI) and blood pressure (BP) in a Chinese population with 26 year follow-up. The study included 4211 schoolchildren aged 6-17 years in Hanzhong, Shaanxi Province, China. Body weight, height, waist circumference, and BP were measured in 1987, 1989, 1992, 1995 and 2013. Cox proportional hazards model were fitted to examine the effect of BMI on BP. At the 26 year follow-up, 6.93% of male and 3.43% of female subjects had high SBP, and 12.8% of male and 4.56% of female had high DBP. The average age of subjects with high SBP was 40.3 years in males and 41.4 years in females; while the average age with high DBP was 38.1 years in males and 38.9 years in females. Obese subjects were 2.96 times and 2.88 times more likely to have high SBP and high DBP than normal weight counterparts, respectively; while overweight subjects were 1.81 times and 2.03 times more likely to have high SBP and high DBP, respectively. These findings underscore the urgent need to prevent increasing body weight. Targeting intervention in adolescence may be a critical method for preventing high BP in later life.
