Study of relationship between BMI, WHR and prevalence rate of metabolic syndrome

  Objective   To explore the relationship between body mass index(BMI), waist to hip ratio(WHR)and the prevalence rate of hypertension, hyperglycemia and disorder in lipo-metabolism amongmental lobourers and to provide reference for further prevention and control of chronic disease.

  Methods   4 726 subjects(above 35 years old)were selected by cluster sampling.The comparison of prevalence rate of the metabolic abnormalities in different abonormal BMI, WHR groups.

  Results   The rate of the BMI abnormal and WHR abnormal were 36.5% and 40.0% respectively, increasing along with age.The prevalence rate of hyperglycemia in Abnormal WHR group was significantly higher than that of abnormal BMI group(P < 0.001).Their relative risk were 3.22 and 1.90 respectively, their 95% confidence in interval(CI)were 2.50~4.15 and 1.39~2.61.

  Conclusion   Obesity, expecially in obesity of abnormal type, may increase the risk of the metabolic abnormalities.Prevention and intervention of obesity are in urgent need among senior mental lobourers.
