Relationship Between Body Composition And Metabolic Syndrome In Adults

Objective:With the economic development and lifestyle change,the incidence of metabolic syndrome(Met S)increases by years,which is especially obvious in overweight people and also exists in normal weight people.This article discusses and analyzes the relationship between body mass index(BMI),waist-to-hip ratio,waist-to-high ratio,body composition and Met S in adult,and determine the optimal cut-off value of relevant indicators,aiming to provide a basis for early screening of Met S,and help to conduct weight intervention and lifestyle guidance.Method:The subjects were adults who underwent health examination at the health promotion center of Sir Run Run Shaw hospital affiliated to Zhejiang University from march,2018 to June,2019.All subjects completed general information collection,blood biochemical tests and body composition tests.SPSS 23.0 was used for data analysis,and differences between groups were compared.Multivariate logistic regression model was used to estimate the odds ratio(OR)of each influencing factor and its 95%confidence interval(CI),and each critical value was obtained.Rusult:After analyzing the test results of 4766 physical examinees,it was found that31.2%of them were overweight and 8.0%were obese.The overall prevalence of Met S was 28.6%,among which 37.1%were males and 18.9%were females,consistent with the gender proportion of overweight and obese population.14.11%of normal weight people and 2%of underweight people had Met S.The prevalence of Met S was related to age,postmenopausal women,BMI,percentage of body fat and other factors.The BMI threshold was 24.19 kg/m~2for men and 22.59 kg/m~2for women.The cut-off value of waist-to-hip ratio was 0.9 for both men and women.The cut-off value of waist-to-height ratio was 0.5 for both men and women.The cut-off value of body fat was 23.46%for men and 29.97%for women.Conclusion:Body composition is closely related to metabolic level,and BMI,waist-to-hip ratio,waist-to-height ratio and changes in body composition can be used as reliable indicators for early screening of Met S.
