Abstract

Bai Ku Yao is an isolated subgroup of the Yao minority in China. Little is known about dyslipidemia in this population. The aim of this study was to compare the effects of demography, diet, and lifestyle on serum lipid levels between the Bai Ku Yao and Han populations. A total of 1,170 subjects of Bai Ku Yao and 1,173 subjects of Han Chinese aged 15-89 years were surveyed by a stratified randomized cluster sampling. The levels of total cholesterol, high density lipoprotein cholesterol, low density lipoprotein cholesterol, apolipoprotein A-I (apoA-I), and apoB were significantly lower in Bai Ku Yao than in Han. Physical activity level and total dietary fiber intake were higher, whereas body mass index (BMI), waist circumference, total energy intake, and total fat intake were lower in Bai Ku Yao than in Han. Hyperlipidemia was positively correlated with BMI, waist circumference, and total energy and total fat intakes and negatively associated with physical activity level and total dietary fiber intake in both populations, but it was positively associated with age and alcohol consumption only in Han. The differences in the lipid profiles between the two ethnic groups were associated with different dietary habits, lifestyle choices, and levels of physical activities.

Highlights

Bai Ku Yao is an isolated subgroup of the Yao minority in China
The present study shows that the levels of serum total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), apolipoprotein A-I (apoA-I), and apolipoprotein B (apoB) in Bai Ku Yao were lower than those in Han
Bai Ku Yao and Han reside in the same region, there were differences in their diet that might account for the observed differences in serum lipid profiles

Summary

Introduction

Bai Ku Yao is an isolated subgroup of the Yao minority in China. Little is known about dyslipidemia in this population. The aim of this study was to compare the effects of demography, diet, and lifestyle on serum lipid levels between the Bai Ku Yao and Han populations. Comparison of demography, diet, lifestyle, and serum lipid levels between the Guangxi Bai Ku Yao and Han populations. Several regional studies have examined serum lipid levels in Chinese populations [17,18,19], little is known about the differences in lipids between Han and other minority groups in rural areas. Little is known about the association between dietary intake and lifestyle and the serum lipid levels in this population. The present study was undertaken to compare the effects of demographic characteristics, dietary patterns, and other lifestyle factors on the serum lipid levels between the Bai Ku Yao and Han populations from the same region.
