Comparison of serum lipid profiles and the risk factors between the Guangxi Bai Ku Yao and Han nationalities / 中华内分泌代谢杂志

The levels of total cholesterol, high-density lipoprotein-cholesterol, low-density lipoprotein-cholesterol, apolipoprotein (APO) A1 and APO B were lower in Bai Ku Yao than those in Han nationalities (all P<0.01). There was no significant difference in serum triglyceride levels and the ratio of Apo A1 to Apo B between two nationalities. Dyslipidemia was positively correlated with body mass index, waist circumference, total energy and total fat intakes, and inversely correlated with degree of physical activity and total dietary fiber intake in both ethnic groups. In addition, dyslipidemia was also positively correlated with age and alcohol consumption in Han, but not in Bai Ku Yao.

Comparison of hypertension and its risk factors between the Guangxi Bai Ku Yao and Han populations.

OBJECTIVE: Little is known about the prevalence of hypertension in Bai Ku Yao, an isolated subgroup of the Yao minority in China. The aim of this study was to compare the difference in the prevalence of hypertension and its risk factors between the Guangxi Bai Ku Yao and Han populations. METHODS: A cross-sectional study of hypertension in 1170 subjects of Bai Ku Yao and 1173 participants of Han Chinese aged 15-89 was conducted by a stratified randomized cluster sampling. Information on diet and lifestyle was collected with standardized questionnaires. Blood pressure, serum lipids and several anthropometric parameters were obtained in all subjects. RESULTS: Systolic, diastolic and pulse pressure levels and hypertension prevalence (10.85% vs 16.45%, p<0.001) were lower in Bai Ku Yao than in Han. Hypertension was positively correlated with male, age, physical activity, body mass index, waist circumference, total energy, total fat and sodium intakes, and negatively associated with education level and total dietary fibre intake in both ethnic groups (p<0.05-0.001). Hypertension was also positively associated with alcohol consumption in Han. The rates of awareness, treatment and control were lower in Bai Ku Yao than in Han (p<0.05 for all). CONCLUSIONS: The difference in the hypertension prevalence between the two ethnic groups might result from different diet, lifestyle, physical activity level, sodium intake and genetic factors.

Associations of diet and lifestyle with hyperlipidemia for middle-aged and elderly persons among the Guangxi Bai Ku Yao and Han populations.

BACKGROUND: There are fifty-six ethnic groups in China. Han is the largest group and Bai Ku Yao is the isolated subgroup of the Yao minority. Little is known about the difference in the prevalence of hyperlipidemia between the Han and other minority groups in the rural areas. OBJECTIVE: The aim of this study was to compare the associations of diet and lifestyle factors with hyperlipidemia for middle-aged and elderly persons between the Guangxi Bai Ku Yao and Han populations. DESIGN: This is a cross-sectional study. A total of 485 subjects of Bai Ku Yao and 501 subjects of Han Chinese ethnicity aged 40 years and older were surveyed by a stratified cluster random sampling technique. METHODS: Information on demography, dietary intake, and lifestyle factors was collected by standard questionnaires. Blood pressure, height, weight, waist circumference, and serum lipid levels were measured, and body mass index (BMI) was calculated as weight (kg) divided by height (m) squared. RESULTS: The prevalence rates of hypercholesterolemia, hypertriglyceridemia, and hyperlipidemia in Bai Ku Yao and Han were 19.59% vs 36.13% (P<0.001), 13.81% vs 16.97% (P>0.05), and 28.45% vs 43.11% (P<0.001), respectively. Hyperlipidemia was positively correlated with BMI; waist circumference; total energy, total fat, and saturated fatty acids intakes; and negatively associated with sex (women were higher), physical activity, and total dietary fiber intake in Bai Ku Yao (P<0.05 to 0.001), whereas hyperlipidemia was positively associated with BMI; waist circumference; total energy, total fat, and saturated fatty acids intakes; and negatively associated with physical activity and total dietary fiber intake in Han (P<0.05 to 0.001). CONCLUSIONS: The prevalence of hyperlipidemia was significantly lower among ethnic Bai Ku Yao than among ethic Han individuals, which might mainly be attributed to the more favorable dietary patterns, lifestyle choices, and physical activity levels in the former ethnic group.
