Abstract

Objective To study the blood lipid level of the Li nationality in Hainan Island, and to compare it between Li nationality and other people. To analyse the effects of the way of life style and the Polymorphisms of blood lipid gene on the levels of blood lipids.

Methods The epidemiological study was carried out in a natural population 1000 (500 samples from the Li nationality and 500 samples from the Han nationality) individuals aged aged between 30 and 50 from Li Nationality in Hainan area by cluster and random sampling. To measure TC, TG, LDL-C, HDL-C according to “Suggestion on protocol of measuring serum lipdaemia and standardisation”, the data were analysed by SPSS 13.0.

Results There were no differences about the levels of TC, TG, HDL-C and LDL-C between the Li nationality and the Han nationality, but there were significant difference about the levels of HDL-C between two population (p<0.05). The levels of HDL-C in the Li nationality was significantly higher than that in the Han nationality among female (p<0.05), and the levels of TG in the Han nationality was significantly higher than that in the Li nationality among male (p<0.05). The levels of HDL-C in the Li nationality was significantly higher than that in the Han nationality in the group of age 30–39 and the group of age 40–49 (p<0.05).

Conclusions There were statistical difference about the levels of the blood lipids between the Li and the Han nationality. The reason could be that the Li nationality living in the poor area who are under low living standard. The different Polymorphisms of blood lipid genes may be one of the causes.
