Dyslipidemia prevalence and serum lipid profiles and ratios among urban and rural residents in Hubei province,2013:a comparison analysis

Objective To compare the dyslipidemia prevalence,serum lipid profiles and ratios between urban and rural residents in Hubei province in 2013 and to provide evidences for the prevention and control of dyslipidemia.Methods Questionnaire survey and laboratory test were conducted among 5 926 urban or rural residents aged 18 and over selected with multi-stage cluster random sampling from 10 disease surveillance points (DSPs) in Hubei province in 2013.SAS 9.2 was used for statistical analysis through design-based complex sampling module.Results After complex weighting,the overall dyslipidemia prevalence rate in urban and rural residents in Hubei province was 32.7%.The prevalence rates for high total cholesterol (TC),triglyceride (TG),low density lipoprotein-cholesterol (LDL-C) and low high density lipoprotein-cholesterol (HDL-C) were 4.5%,12.3%,5.8%,and 21.6%,respectively.The level of serum TC,TG,LDL-C,HDL-C and non-HDL-C were 4.55±0.09,1.44±0.05,2.76±0.07,1.35±0.04,and 3.20±0.07 mmol/L,respectively.The urban residents had significantly higher levels of serum TG (1.57±0.06 vs.1.26±0.03 mmol/L),lower levels of serum HDL-C (1.28±0.02 vs.1.46±0.06 mmol/L) than rural residents (both P<0.01).The male urban residents had higher levels of TG (1.82±0.09 vs.1.30±0.04 mmol/L),non-HDL-C (3.34±0.07 vs.3.11±0.06 mmol/L),lower levels of serum HDL-C (1.21±0.02 vs.1.35±0.03 mmol/L) than female urban residents (P<0.01 for all).The male rural residents had a lower level of serum HDL-C (1.41±0.05 vs.1.51±0.07 mmol/L) than female rural residents(P<0.01).The ratios of TC/HDL,LDL/HDL,non-HDL/HDL,TG/HDL were 3.67,2.20,2.67,and 1.45,respectively,which were all higher among the male residents (3.93,2.33,2.93,and 1.81) than among the female residents (3.41,2.07,2.41,and 1.08) and higher among urban residents (3.85,2.29,2.85,and 1.69) than among rural residents (3.39,2.07,2.39,and 1.07),with statistically differences.Conclusion The dyslipidemia prevalence was high among residents in Hubei province.Compared to rural residents,urban residents showed higher serum TG and lower serum HDL-C.All lipid ratios were higher in male residents than in female residents and higher in urban residents than in rural residents.
