The influence and screening value of percentage of body fat and waist height ratio for hyperlipidemia in physical examination people / 天津医药

ABSTRACT

Objective To evaluate the relationship and screening value of percentage of body fat (BF%) and waist height ratio (WHtR) for hyperlipidemia in physical examination people. Methods A total of 2 668 objects taking physical examination in Henan Province People′s Hospital from September to December 2014 were included in this study. Values of height, body mass index (BMI), waist circumference, body composition and blood lipid level were detected. The receiver oper?ating characteristic curve (ROC) was used to analyze the screening rate of WHtR and BF%on hyperlipidemia with sensitivi?ty, specific and area under the curve (AUC). After stratified by age, waist circumference and BMI, multivariable logistic re?gression analysis was used to investigate the association between hyperlipidemia risk, BF% and WHtR. Results The screening accuracy rate on hyperlipidemia was higher for BF%, AUC was 0.79 in both female and male people. Among wom?en with BMI<18.5 kg/m2 and 18.5~<24 kg/m2, the risk of hyperlipidemia was higher in superfatted group than that of normal group. There was no correlation between WHtR and hyperlipidemia. Among men older than 40 y or with abnormal waist cir?cumference (≥85 cm), the risk of hyperlipidemia was higher in superfatted group than that of normal group, but not associat?ed with WHtR. Conclusion The BF%is a better screening indicator for hyperlipidemia compared with that of WHtR and BMI. Women with BMI<18.5 kg/m2 and 18.5~<24 kg/m2 and men older than 40 y or with waist circumference over 85 cm are suggested to do body composition tests to improve screening accuracy for hyperlipidemia.
