Diet, lifestyle, and blood pressure of the middle-aged and elderly in the Guangxi Bai Ku Yao and Han populations

BACKGROUND: Bai Ku Yao is an isolated subgroup of the Yao minority in China. Little is known about the association of diet and lifestyle with the prevalence of hypertension in this population. METHODS: A total of 485 subjects of Bai Ku Yao and 501 participants of Han Chinese aged 40-89 were surveyed using stratified randomized cluster sampling. Information on diet and lifestyle was collected by using standard questionnaires. Blood pressure (BP) and serum lipid levels were measured. RESULTS: Physical activity levels, carbohydrate, vegetal protein, and dietary fiber intake were higher in Bai Ku Yao than in Han, whereas educational level, height, weight, body mass index (BMI), waist circumference, and total energy, fat, protein, dietary cholesterol, and salt intake were higher in Han than in Bai Ku Yao. Systolic, diastolic, and pulse pressure (PP) levels and the prevalence of hypertension (21.9% vs. 28.9%, P < 0.05)were lower in Bai Ku Yao than in Han. Hypertension was positively correlated with age, physical activity,BMI, and waist circumference, as well as with total energy, fat, and salt intake, and negatively associated with educational levels and dietary fiber intake in both ethnic groups (P < 0.05 for all). Hypertension was also positively correlated with triglycerides (TGs) in Bai Ku Yao and alcohol consumption in Han (P < 0.05 for each). CONCLUSIONS: The differences in BP levels and the prevalence of hypertension among the middle-aged and elderly between Bai Ku Yao and Han might result from different dietary patterns, lifestyle choices, physical activity levels, sodium intake, and even genetic factors.

Relationship between the low density lipoprotein receptor gene polymorphism and serum lipid levels in the Guangxi Bai Ku Yao population

Objectives Bai Ku Yao(White-trousers Yaos)is a special branch of Yao minority in China.They are now living in both Lihu and Baxu villages,Nandan County, Guangxi,China.The population size is about 30,000.The special customs and culture of Bai Ku Yao,including their special clothing,intra-ethnic marriages and alcohol intake are still completely conserved to the present day.In previous epidemiologic studies,we found that the serum lipid levels and the prevalence of hyperlipidaemia were lower in Bai Ku Yao than in Han Chinese from the same region.This ethnic difference in serum lipid profiles is still not well known.We hypothesized that there may be significant differences in some genetic polymorphismsssociation of low density lipoprotein receptor (LDL-R) genepolymorphism and several environmental factors with serum lipid levels in the Guangxi Bai Ku Yao and Han populations.Methods A total of 1024 subjects of Bai Ku Yao and 792 participants of Han Chinese were stud- ied by a stratified randomized cluster sampling.Epidemiological survey was carried out using internationally standardized methods.Information on demographics,socioeconomic status, and lifestyle factors was collected with standardized questionnaires. The height,weight,waist circumference,blood pressure, and serum total cholesterol(TC),triglyceride(TG), high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C),apolipoprotein(Apo) A1, and ApoB were measured.Body massindex(BMI,kg/m2) was calculated.Genotyping of the LDL-RAvaⅡwas performed by polymerse chain reaction and restriction fragment length polymorphism combined with gel electrophoresis,and then confirmed by direct sequencing.Results(l)The height,weight,serum TC,HDL-C,LDL-C,ApoAl levels and the ratio of ApoAl to ApoB were lower in Bai Ku Yao than in Han Chinese(P<0.01 for all),whereas the percentage of subjects who consumed alcohol or smoked cigarettes was higher in Bai Ku Yao than in Han Chinese(P<0.01 for each).(2) The frequency of A+ allele in Bai Ku Yao was 34.     

Association of the LIPG 584C&gt;T polymorphism and serum lipid levels in the Guangxi Bai Ku Yao and Han populations

The aim of the present study was to eveluate the association of MTHFR C677Tpolymorphism and several environmental factors with serum lipid levels in the Guangxi Bai Ku Yao and Han populations.Methods A total of 780 subjects of Bai Ku Yao and 686 participants of Han Chinese were randomly selected from our previous stratified randomized cluster samples.Genotyping of the MTHFR C677T was performed by polymerase chain reaction and restriction fragment length polymorphism combined with gel electrophoresis,and then confirmed by direct sequencing.Results The levels of serum total cholesterol(TC),high-density lipoprotein cholesterol (HDL-C),low-density lipoprotein cholesterol(LDL-C), apolipoprotein(Apo) AI and ApoB were lower in Bai Ku Yao than in Han(P<0.05-0.001).The frequency of C and T alleles was 77.4%and 22.6%in Bai Ku Yao,and 60.9%and 39.1%in Han(P<0.001);respectively.The frequency of CC,CT and TT genotypes was 58.7%,37.3%and 4.0%in Bai Ku Yao,and 32.6%,56.4%and 11.0%in Han(P< 0.001);respectively.The levels of TC and LDL-C in both ethnic groups were significant differences among the three genotypes(P<0.05-0.01).The T allele carriers had higher serum TC and LDL-C levels than the T allele noncarriers. The levels of ApoB in Han were significant differences among the three genotypes(P<0.05).The T allele carriers had higher serum ApoB levels as compared with the T allele noncarriers. The levels of TC,TG and LDL-C in Bai Ku Yao were correlated with genotypes(P<0.05-0.001),whereas the levels of LDL-C in Han were associated with genotypes(P< 0.001).Serum lipid parameters were also correlated with sex, age,body massindex,alcohol consumption,cigarette smoking, and blood pressure in the both ethnic groups.Conclusions The differences in serum TC,TG,LDL-C and ApoB levels between the two
