Abstract：Objective To explore the prevalence, risk factors and ethnic differences of dyslipidemia between Mulam and Miao adult women in Guangxi.Methods From July 2012 to August 2013, a total of 444 Mulam and Miao adult women were randomly selected from Luocheng and Rongshui counties of Guangxi, respectively. Questionnaire and blood lipids, including total cholesterol(TC), triacylglycerol(TG), low-density lipoprotein (LDL-C) and high-density lipoprotein(HDL-C), were conducted, and body compositions were measured by bioelectrical impedance analysis. The level of blood lipid, the type and prevalence of dyslipidemia in Mulam women were compared with those of Miao, and the relationship between the dyslipidemia and body composition was analysed.Results There were significant statistical differences in the levels of TC, TG and LDL-C between Mulam and Miao women, and TC, TG in Miao women were higher than those in Mulam(P＜0.01); The prevalence of dyslipidemia in Miao women was significantly higher than that in Mulam(χ2=5.420, P＜0.05). Hypercholesteremia was the most common type of dyslipidemia in Miao women, while the high LDL-C was the most common type of dyslipidemia in Mulam women. Compared with the non-dyslipidemia group in the same ethnicity, the dyslipidemia group showed higher age, fat mass, visceral (subcutaneous) fat content, percentage of body fat (BF%), BMI, waist hip ratio(WHR), years of menopause and the number of children(P＜0.05). To compare both different ethnic dyslipidemia groups, Miao women showed higher weight, fat mass, visceral (subcutaneous) fat content, BF%, BMI and WHR than those in Mulam, significantly(P＜0.01). Logistic regression showed that the age, BMI, WHR, BF%,years of menopause and the number of children were positively related to dyslipidemia in both Miao and Mulam women(OR>1, P<0.05).Conclusions There are differences in the prevalence and pattern of dyslipidemia between Miao and Mulam adult women. The age, BMI, WHR, BF%, status and years of menopause, and the number of children are the risk factors for dyslipidemia in Miao and Mulam women. WHR and BF% are better than BMI to predict the dyslipidemia.
