title: [Relationship between hypertension and percentage of body fat, in children of Anhui province].
abstract: OBJECTIVE
  To study the situation of hypertension among children in Anhui province and to analyze its association with the percentage of body fat.
  
  
  METHODS
  A total of 8 890 aged 7-17 years old children, were tested for blood pressure and thickness of skin fold in Anhui province. Hypertension in children was diagnosed referring to the 2010 Chinese guidelines for the management of hypertension (revised in 2010). The percentage of body fat was calculated according to the thickness of skin fold and specific formulas. METHODS used for statistics analysis would include t test, χ(2) test while logistic regression was used to analyze the relationship between percentage of body fat in children and adolescents. In total, 8 890 subjects aged 7-17 years were recruited, in Anhui province.
  
  
  RESULTS
  The prevalence of hypertension in Children aged 7-17 was 13.6%, with the total number of hypertension as 1 210, in Anhui province. There were significant differences in the prevalence of hypertension among urban and rural children. Both prevalence of hypertension among boys and girls in urban area appeared higher than those in the rural area. In the urban areas, the prevalence rates of hypertension in both boys and girls were higher than the ones in rural area (χ(2) values were 36.36, 7.79, 42.10 and 13.77, respectively, and P<0.01). Differences of the percentage of body fat between boys and girls from the rural or urban areas were both significant.OR values of the boys and girls of group P(40)- and P(60)-were 1.65 and 1.75, respectively. Risks of hypertension in boys and girls showed significantly increase by P(40) and P(60), respectively. The prevalence of hypertension in both boys and girls increased along with the increase of the percentage on body fat.
  
  
  CONCLUSIONS
  Since higher percentage of body fat could increase the risk of hypertension, reduction of body fat content would be beneficial to the success of prevention and control of hypertension in children.
