Prevalence of valvular heart diseases and associated risk factors in Han, Uygur and Kazak population in Xinjiang, China.

ABSTRACT:

Background

Valvular heart diseases (VHD) is very common in clinical practice and has became the subject of growing attention in the field of cardiovascular medicine. Our aim was to assess the prevalence and correlates of VHD in the general population in Xinjiang, China.

Methods

Using a 4-stage stratified cluster random sampling method, a total of 14618 participants were recruited in the Cardiovascular Risk Survey (CRS) study. The participants' personal information, medical history were assessed by questionnaire. VHD was diagnosed by transthoracic echocardiography. We carried out the statistical analysis utilizing SPSS Statistics version 19.0.

Results

In the total study group, VHD was observed in 1397 (9.65%) individuals. The prevalence rates of VHD in Han, Uygur and Kazak group are 13.51%, 2.71% and 12.29% respectively. The prevalence rates of VHD increased strikingly with age (all P < 0.001). The results of multinomial regression analysis indicated that VHD were related to age in Han group, to age smoking and hypertension in Uygur group, to age and hypertension in Kazak group.

Conclusion

Our research provides a unique prevalence rate of VHD in Xinjiang natural population. The result suggests that VHD are notably common in this population (9.65%) and increase with age. There exists significant difference of prevalence rate between ethnics. The main risk factors of VHD are age, hypertension and smoking. Valvular heart diseases should be regarded as a serious and growing public-health problem.

Project description:BackgroundDyslipidemia is a predisposing factor for coronary heart disease (CHD). High-intensity statin therapy is recommended as secondary prevention. ABCB1 and SLCO1B1 genes influence the efficacy and safety of statins. Xinjiang is a multi-ethnic area; however, little is known about the prevalence of dyslipidemia and gene polymorphisms of ABCB1 and SLCO1B1 in minority groups with CHD.ObjectiveTo measure levels of lipid and apolipoprotein and the prevalence of dyslipidemia and gene polymorphisms of ABCB1, SLCO1B1 in Han, Uygur, Kazak, Hui, Tatar, Kirgiz, and Sibe populations with CHD in Xinjiang.MethodsThis descriptive retrospective study compares lipid levels in ethnic groups using Kruskal-Wallis test or analysis of variance. The study compared gene polymorphisms and the prevalence of dyslipidemia among different ethnic groups using the chi-square test. The lipid profiles in plasma were measured before lipid-lowering therapy using commercially available kits. Genotyping of SLCO1B1 and ABCB1 variants was performed using sequencing by hybridization.ResultsA total of 2218 patients were successfully screened, including 1044 Han, 828 Uygur, 113 Kazak, 138 Hui, 39 Tatar, 36 Kirgiz, and 20 Sibe patients. The overall mean age was 61.8 ± 10.8 years, and 72.5% of participants were male. Dyslipidemia prevalence in these ethnic groups was 42.1, 49.8, 52.2, 40.6, 48.7, 41.7, and 45.0%, respectively. The prevalence of dyslipidemia, high total cholesterol (TC), high triglycerides (TG), and high low density lipoprotein cholesterol (LDL-C) differed significantly among the groups (P = 0.024; P < 0.001; P < 0.001; P < 0.001, respectively). For the Han group, high LDL-C, high TC, and high TG prevalence differed significantly by gender (P = 0.001, P = 0.022, P = 0.037, respectively). The prevalence of high TC, high TG, and low high density lipoprotein cholesterol (HDL-C) differed significantly by gender in the Uygur group (P = 0.006, P = 0.004, P < 0.001, respectively). The prevalence of high TC in Hui patients significantly differed by gender (P = 0.043). These findings suggest that polymorphisms in ABCB1 and C3435T differ significantly across ethnicities (P < 0.001).ConclusionsThe prevalences of dyslipidemia, high TC, high TG, and high LDL-C in Han, Uygur, Kazak, Hui, Tatar, Kirgiz, and Sibe CHD patients in Xinjiang differed concerning ethnicity. Ethnic, gender, and lifestyle were the key factors that affected the lipid levels of the population. The prevalence of polymorphisms of ABCB1 and C3435T significantly differed across ethnicities. These findings will aid the selection of precision lipid-lowering medications and prevention and treatment of CHD according to ethnicity in Xinjiang.

Project description:BackgroundThe association of genetic polymorphisms of klotho gene with aging has not been thoroughly examined. Previous studies showed that longevity in the Uygurs was considerably greater than in Kazaks in Xinjiang. This study aimed to investigate the difference of renal function and Klotho gene polymorphisms between Kazak and Uygur normal populations in Xinjiang, China.Material/methodsA total of 249 Uygur and 386 Kazak clinically normal subjects were included in this study. Four single-nucleotide polymorphisms (rs1207568, rs564481, rs9527025, and rs9536314) of the klotho gene were genotyped using the ABI SNaPshot method. Estimated glomerular filtration rate (eGFR) was calculated according to the Chinese simplified MDRD equation.ResultsThere were significant differences between Kazak and Uygur healthy populations in both allele frequencies and genotype distributions in rs9527025 and rs9536314 (P<0.05, respectively). When the subjects were divided into 2 groups according to the genotypes of the klotho gene polymorphism, in the GA+AA genotype distributions of the rs1207568, the differences I serum creatinine and estimated glomerular filtration rate between the Kazak and Uygur groups were statistically significant (P<0.05, respectively). In CC genotype of rs564481, serum creatinine was significantly higher in Kazaks compared with Uygurs (P<0.05). In GG genotype of rs9527025, serum creatinine was significantly higher in the Kazak group compared with the Uygur group (P<0.05), as well as in CG+CC genotype of rs9527025 (P<0.05). Serum creatinine was significantly higher in the Kazak group compared with the Uygur group in TT genotype of rs9536314 (P<0.05), as was GT+GG genotype of rs9536314. Haplotype analysis indicated that the frequencies of ACGT, GTGT, and GCCG haplotypes were significantly different between Kazak and Uygur healthy populations (P=0.04, P=0.018, P=0.000, respectively).ConclusionsSignificant differences in klotho gene rs9527025 and rs9536314 polymorphisms were found between the Uygur and Kazak populations.

Project description:ObjectivesTo estimate the prevalence, ethnic differences and associated risk factors of myopic maculopathy in Han and Uygur adults in Xinjiang, China.Design and settingA cross-sectional study with multistage, stratified cluster sampling method was conducted in Xinjiang, China.ParticipantsA total of 4023 Han and Uygur participants aged 40 years and older were eligible for the study.Outcome measuresThe association between myopic maculopathy and its risk factors was screened using the generalised estimating equation (GEE) model. We also investigated whether ethnic differences exist between Han and Uygur populations affected by myopic maculopathy. Myopic maculopathy was defined in accordance with International Photographic Classification and Grading System for Myopic Maculopathy.ResultsA total of 3044 subjects (5946 eyes) were included in our study (1736 Han and 1308 Uygur individuals). The participants consisted of 1256 (41.3%) men and 1788 (58.7%) women. The average age was 52.2±9.4 years, and the mean spherical equivalent (SE) was -0.18±2.31 dioptre (D). Myopic maculopathy was detected in 198 eyes of 138 participants. The age-adjusted prevalence of myopic maculopathy reached 5.8% (95% CI 4.8 to 6.8). In the GEE model, myopic maculopathy was significantly associated with old age (per year; OR: 1.16; 95% CI 1.13 to 1.19; p<0.001) and myopic SE (per -1 D; OR: 1.48; 95% CI 1.40 to 1.56; p<0.001). No ethnic differences were detected between Han (98, 5.7%) and Uygur population (40, 3.1%) in terms of the prevalence of myopic maculopathy (OR=0.89; 95% CI 0.53 to 1.48; p=0.64). Neither urbanisation (p=0.38) nor the level of education (p=0.92) was associated with myopic maculopathy.ConclusionsA high age-adjusted prevalence of myopic maculopathy was observed in Han and Uygur populations in Xinjiang, China. Old age and high degree of myopic refraction were independent risk factors for myopic maculopathy. No ethnic differences were detected in Han and Uygur populations affected by myopic maculopathy.
