Association between different types of obesity and blood pressure among children and adolescents in Ningxia

Objective To analyze the association between different types of obesity and blood pressure among children and adolescents in Ningxia,and provide a reference for the prevention and control of high blood pressure among children and adolescents.Methods Data of 2014 National Survey on Students' Constitution and Health of Ningxia was used to analyze the association between different types of obesity and blood pressure.A total of 11 260 children and adolescents were included into the analysis according to the screening criteria.Results The total detection rate of obesity among children and adolescents in Ningxia was 5.2%.The detection rate of different types of obesity was 9.5%,0.5% and 4.7%,respectively.And the total detection rate of hypertension was 13.8%.The partial correlation results suggested that BMI,waist circumference were positively correlated with SBP and DBP(r=0.509,0.515,0.372,0.384,P<0.01),and the change trend of SBP and DBP in different obesity types was as follows:combined obesity>abdominal obesity>general obesity>normal weight.The detection rates of hypertension in different types of obesity were 11.1%,24.2%,14.0%,41.9%,respectively.When compared with normal weight children,combined obesity had the highest risk of elevated blood pressure,followed by abdominal obesity,the odds ratios were 5.8(4.8-7.0),4.4(2.1-9.5),2.3(1.8-2.8),respectively.Conclusion Obesity is one of the risk factors for elevated blood pressure in children and adolescents;combined obesity was more associated with high blood pressure.And the prevention of obesity should give the priority to the prevention of high blood pressure among children.
