[Relationship between the body mass index, waist circumference and lipids levels among adults in Shenzhen].

OBJECTIVE: To study the relationship between the body mass index (BMI), waist circumference (WC) and lipids levels, dyslipidemia among adults. METHODS: Totally 12 communities from 8 districts were sampled through stratified randomized sampling, 75 households from each community were sampled by random sampling for questionnaire survey, physical examination and laboratory tests. RESULTS: Within different BMI categories, the triglyceride (TG) in higher BMI group were higher than in lower BMI group, and the high density lipoprotein-c (HDL-c) in higher BMI group were lower than in higher BMI group; Within different WC categories, the TG, total cholesterol (TC), low density lipoprotein-c (LDL-c) in higher WC group were higher than in lower WC group. With the increase of BMI/WC, the levels of TG, TC and LDL-c showed a rising trend (P<0.05), HDL-c showed a falling trend (P<0.05). With the increase of BMI, the odds ratios (ORs) of high TG, high TC, low HDL-c, high LDL-c and dyslipidemia showed a rising trend (P<0.05), and with the increase of WC, the ORs of high TG, high TC, high LDL-c and dyslipidemia showed a rising trend (P<0.05). There were positive partial correlations between BMI/WC and TG, TC, HDL-c, LDL-c. HDL-c had a higher correlation with BMI (P<0.05), TC had a higher correlation with WC (P<0.05). CONCLUSION: BMI and WC were independently associated with blood lipids levels, and high BMI and WC were the risk factors for dyslipidemia.
