Abstract:
Objective To survey small dense low-density lipoprotein cholesterol(sdLDL-C)distribution among different popula-tions,and analyze its relationship with lipid component.Methods 986 cases of people who underwent medical examination in the hospital were recruited in the study.There were 654 people with normal concentrations of serum blood lipids(normal blood lipids group),according to sex and age they were divided into groups.The people whose serum lipids concentrations increased above the normal range were divided into TG increasing group,LDL-C increasing group and joint increasing group according to the type of lip-ids componet increased.Serum sdLDL-C,LDL-C,TG,TC,HDL-C,ApoAⅠ and ApoB were determind in the people mentioned a-bove,and the correlation between sdLDL-C and TG,TC,HDL-C,ApoAⅠ,ApoB concentrations were analyzed.Results SdLDL-C began to decline after the age of 70,the difference was statistically significant(P <0.05 );the ensemble average of the males was higher than that of females,the difference was statistically significant(P <0.05).The serum sdLDL-C cocentrations of all the serum lipis increasing groups were significantly higher than those of normal blood lipids group,the difference was statistically significant (P <0.05 ).SdLDL-C concentrations were positively correlated with TC,TG,ApoB(r =0.254,0.589,0.302),and was negative correlated with HDL-C and ApoA Ⅰ (r = - 0.421,- 0.275,- 0.311 ).Conclusion There was a positive correlation between sdLDL-C and TC,TG,ApoB,and sdLDL-C was negatively correlated with HDL-C,ApoAⅠ,which can accurately reflect the overall status of lipid metabolism.
