Abstract:
OBJECTIVETo estimate the prevalence of elevated blood pressure (EBP) in Chinese children and identify individual and family factors associated with EBP.
METHODSA nationwide cross-sectional study was conducted in 2010 using stratified cluster sampling. Participants' blood pressure was measured, and their parents completed a questionnaire on personal and family characteristics. Prevalence and correlates of EBP were assessed.
RESULTSAmong a total of 24,333 participants, 20.2% of boys and 16.3% of girls had EBP. The prevalence of EBP increased with the ascending trend of waist circumference, Waist-to-height ratio, and body mass index. The adjusted prevalence ratios (aPRs) for obese boys and girls were 2.50 and 2.97, respectively. Fewer urban boys (16.2%) had EBP than rural boys (21.7%). Boys with a family history of hypertension were 12% more likely to have EBP. Children whose mothers received a college education tended to have lower likelihood of EBP; with an aPR was 0.85 among boys and 0.78 among girls.
CONCLUSIONEBP is common among obese students and those who have a family history of hypertension. A negative association between mothers' education levels and EBP risk in children was found.
