Abstract
OBJECTIVE: This study aimed to compare the secular trends of high blood pressure (HBP) and the effects of overweight and obesity on HBP between Chinese ethnic minority and Han children and adolescents . METHODS: Data were collected from 224,151 Chinese ethnic minority and 664,094 Han children and adolescents aged 7 to 18 years during three successive, national cross-sectional surveys (2005, 2010, and 2014). Logistic regression and population-attributable risk analyses were used to evaluate the association between HBP and overweight and obesity. RESULTS: HBP prevalence in ethnic minorities increased from 4.8% in 2005 to 6.3% in 2014, which was significantly higher than the variable HBP trends (4.1% to 5.5%) in Han children and adolescents. Both ethnic minority and Han children and adolescents experienced a rapid increase in overweight and obesity, but the pace of growth for HBP, overweight, and obesity was faster in ethnic minorities than in their Han peers. Moreover, the effects of obesity on HBP in ethnic minorities showed a sustained increase over time but were stable for the Han. CONCLUSIONS: Higher HBP prevalence, faster obesity increases, and a stronger impact of obesity on HBP in children and adolescents of Chinese ethnic minorities predict their looming burden of HBP, which suggests that attention to the cardiovascular disease risks in children and adolescents from ethnic minorities is indicated to reduce their future adult risk.
