Prevalence of hypertension in the Guangxi Bai Ku Yao populations / 中华心血管病杂志

<p><b>OBJECTIVE</b>To observe the prevalence of hypertension and associated risk factors in the Guangxi Bai Ku Yao populations.</p><p><b>METHODS</b>A total of 1170 subjects of Bai Ku Yao aged 15 and over were surveyed by a stratified randomized cluster sampling. Blood pressure, body height, weight, waist circumference, serum lipid and apolipoprotein levels were measured, and body mass index (BMI) were calculated, matched 1173 subjects of Han Chinese from the same region served as control.</p><p><b>RESULTS</b>The standardized prevalence of hypertension in Bai Ku Yao was significantly lower than that in Han (11.53% vs.16.79%, P < 0.01). The mean levels of systolic, diastolic blood pressure, and pulse pressure in Bai Ku Yao were also significantly lower than those in Han [(115.7 +/- 16.3) vs. (120.0 +/- 16.3) mm Hg (1 mm Hg = 0.133 kPa), P < 0.01; (74.1 +/- 9.4) vs. (75.9 +/- 10.4) mm Hg, P < 0.01; and (41.6 +/- 12.0) vs. (44.2 +/- 11.2) mm Hg, P < 0.01; respectively]. Hypertension was positively correlated with male, age, physical activity, BMI, waist circumference, and the intakes of total energy, total fat, and sodium, and negatively associated with education level in both ethnic groups (P < 0.05 - 0.01), but was positively associated with alcohol consumption only in Han. The rates of awareness, treatment and control of hypertension were significantly lower in Bai Ku Yao than those in Han population [(11.81% vs. 21.76%), P < 0.05; (5.51% vs. 12.95%), P < 0.05; and (2.36% vs. 8.29%), P < 0.05; respectively].</p><p><b>CONCLUSION</b>The prevalence of hypertension was significantly lower in Bai Ku Yao population than in Han population and diet, low sodium intake, life style, and genetic factors might be responsible for the lower hypertension prevalence in Bai Ku Yao population.</p>

Relationship between the polymorphism of the variable number of tandem repeats region 3' of the apolipoprotein B gene and serum lipid levels in the Guangxi Heiyi Zhuang populations / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To study the relationship between the polymorphism of the variable number of tandem repeats region 3' of the apolipoprotein B gene (3'APOB-VNTR) and serum lipid levels in the Guangxi Heiyi Zhuang population.</p><p><b>METHODS</b>A total of 548 people of Heiyi Zhuang nationatity were surveyed by a cluster sampling. Epidemiological data were collected and serum lipid and apolipoprotein levels were measured. The genotypes and alleles of the 3' APOB-VNTR were determined by polymerase chain reaction combined with gel electrophoresis, and then analyzed by direct sequencing in the most common alleles. The results were compared with those in 496 people of Han nationality also live in that district.</p><p><b>RESULTS</b>There were 19 alleles of the 3'APOB-VNTR in both ethnic groups. They were hypervariable elements (HVEs) 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62 and 64, but HVEs 56 and 58 in Heiyi Zhuang nationality and HVEs 48 and 62 in Han nationality were not be detected. The most common allele is HVE32 in Heiyi and Zhuang nationality (25.9%), and HVE34 in Han nationality (27.2%). The frequencies of HVEs 26, 30, 46, heterozygote, and short alleles (< 38 repeats, S) were higher in Heiyi Zhuang nationality than in Han nationality, whereas the frequencies of HVEs 34, 38, 40, homozygote, and long alleles (>or= 38 repeats, L) were lower in Heiyi Zhuang nationality than in Han nationality. The levels of total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and apolipoprotein (apo) B in Heiyi Zhuang nationality were higher in VNTR-LS (carrier of one long and one short alleles) than in VNTR-LL genotypes (the individual carrying two long alleles) genotypes. The levels of TC, triglycerides, HDL-C and apo B in Heiyi Zhuang nationality were also higher in homozygotes than in heterozygotes. There were no significant differences in the detected lipid parameters between the VNTR-SS (carrier of two short alleles) and VNTR-LS or VNTR-LL genotypes in both ethnic groups.</p><p><b>CONCLUSION</b>The 3'APOB-VNTR polymorphism is found to be significant difference between Heiyi Zhuang nationality and Han populations, and is associated with the serum lipid levels in Heiyi Zhuang nalionality but not in Han nationality.</p>

Survey on blood pressure and serum lipids in Hei Yi Zhuang Chinese living in Guangxi / 中华心血管病杂志

<p><b>OBJECTIVE</b>To investigate the levels of blood pressure and serum lipids, and examine the relationship between hypertension and hyperlipidemia in Hei Yi Zhuang Chinese living in Guangxi.</p><p><b>METHODS</b>A total of 1056 people of Hei Yi Zhuang ethnicity were studied. Blood pressure, body height, body weight, and serum levels of lipids and apolipoprotein were measured. The data were compared with those in 925 people of Han ethnicity, who live in the same region.</p><p><b>RESULTS</b>Systolic blood pressure and pulse pressure were significantly higher in Hei Yi Zhuang than Han Chinese (P < 0.001). The prevalence of isolated systolic hypertension and hypertension was also significantly higher in Hei Yi Zhuang than Han Chinese (P < 0.001). Serum concentrations of total cholesterol, triglycerides, low-density lipoprotein cholesterol, and apolipoprotein (Apo) B, and the prevalence of hypercholesterolemia and hyperlipidemia were significantly lower in Hei Yi Zhuang than Han Chinese (P < 0.05). Serum concentrations of high-density lipoprotein cholesterol and the Apo A1 to Apo B ratio were significantly higher in Hei Yi Zhuang than Han Chinese (P < 0.001). The prevalence of hypertension in Hei Yi Zhuang Chinese was positively associated with triglycerides (r = 0.425, P < 0.05), whereas the prevalence of hypertension in Han Chinese was positively correlated with total cholesterol (r = 0.623, P < 0.001).</p><p><b>CONCLUSION</b>The present study revealed a significant difference in blood pressure and serum lipids between Hei Yi Zhuang and Han ethnic groups, and an association between hypertension and hyperlipidemia.</p>

Relationship between the polymorphism of lipoprotein lipase gene and serum lipid levels in the Guangxi Hei Yi Zhuang population / 中华检验医学杂志

0.05 for all).Conclusions The allelic frequencies of LPL gene at Pvu Ⅱ locus in Hei Yi Zhuang were different from those in Han,but the genotypie frequencies in Hei Yi Zhuang were not different from those in Han.There was no significant correlation between the polymorphism of LPL gene at Pvu Ⅱ site and the serum lipid levels in two ethnic groups.
