Prevalence of Isolated Diastolic Hypertension and Associated Risk Factors among Different Ethnicity Groups in Xinjiang, China.

ABSTRACT:

Objectives

Little is known about isolated diastolic hypertension (IDH) among different ethnicity groups. We aimed to investigate the prevalence and risk factors for IDH among the major ethnicity population i.e. Han, Uygur and Kazakh in Xinjiang, northwestern part of China.

Methods

In total, 14,618 adult participants (7,799 males, 6,819 females) were recruited from the Cardiovascular Risk Survey conducted during 2007 and 2010. Blood pressure, body mass index and standard lipid profile and fasting glucose level from plasma were measured.

Results

The overall prevalence of IDH was 10.8% in the Han, 4.5% in the Uygur and 8.7% in the Kazakh populations. When stratified by gender, IDH prevalence was 9.8% in men and 6.8% in women (P<0.001). The prevalence of IDH also varied significantly with age and it was highest in those aged 35-44 yrs old (9.7%) and lowest in those over 75 yrs old (4.1%, P<0.001). Multivariate logistic regression analysis showed that overweight (OR = 1.179, 95%CI: 1.015-1.369) or obesity (OR = 1.202, 95%CI: 1.015-1.424), smoking (OR = 1.362, 95%CI: 1.156-1.604) and high total cholesterol (TC) hyperlipidemia (OR = 1.237, 95%CI: 1.074-1.423) were significantly associated with a higher prevalence of IDH. Identified risk factors for IDH differed among ethnicity groups with male gender, young age (35-44 yrs old), more coffee or tea consumption and high TC hyperlipidemia in the Han; smoking and often coffee or tea consumption in the Uygur and male gender and overweight or obesity in the Kazakh populations.

Conclusions

IDH prevalence in the Han population is higher than that in the Uygur and Kazak populations in Xinjiang, northwestern part of China. Male gender, middle age, overweight or obesity, smoking and high TC hyperlipidemia appear to be relevant risk factors of IDH in adults. Different ethnicity background had different sets of risk factors for IDH.

Project description:Reduction in DNA repair capacity is associated with increased rates of birth defects, cancer, and accelerated aging. According to some earlier studies, genetic polymorphisms in DNA repair genes might influence the repair activities of the enzymes predisposing individuals to cancer risk. Owing to the presence of these genetic variants, inter-individual and ethnic differences in DNA repair capacity have been observed in various populations. Polymorphisms in DNA repair genes and differences in repair capacity between individuals have been widely reported in different cancers. We conducted a case-control study to examine the role of genetic polymorphisms in XRCC1 Gln632Gln (rs3547), Arg399Gln (rs25487), Arg280His (rs25489), Arg194Trp (rs1799782) in the risk of laryngeal cancer in different ethnic groups in Xinjiang. This study included 58 laryngeal cancer patients and 120 healthy controls age- and sex-matched without cancer. The genotypes of XRCC1Gln632Gln (rs3547), Arg399Gln (rs25487), Arg280His (rs25489) and Arg194Trp (rs1799782) were analyzed by PCR-RFLP, and the odds ratio (OR) and 95% confidence interval (CI) were calculated using an unconditional logistic regression model. C/T (hybrid) and T/T (mutant) genotypes of XRCC1 Arg280His (rs25489) revealed no statistical significance in the risk of laryngeal cancer (P>0.05), whereas the genotypes of XRCC1 Gln632Gln (rs3547), Arg399Gln (rs25487), Arg280His (rs25489), Arg194Trp (rs1799782) showed a higher risk than the controls (P<0.01) in Han, Uygur, and Kazak nations. In conclusion, the current study suggests that XRCC1 Gln632Gln (rs3547), Arg399Gln (rs25487), and Arg194Trp (rs1799782) polymorphisms may be associated with laryngeal cancer risk in the Han, Uygur, and Kazakh populations in Xinjiang. Individuals carrying genotype Arg/Gln+Gln/Gln showed a greater risk than those carrying Arg/Arg for laryngeal cancer in the Han, Uygur and Kazakh ethnic groups, and the odds ratios are 1.47, 1.32, and 0.77.

Project description:BackgroundEthnic differences in non-invasive measurements of carotid atherosclerosis are being increasingly reported, but the association between carotid atherosclerosis and different subtypes of hypertension in adult populations is not fully understood in different ethnicities. We aimed to investigate the association of carotid atherosclerosis with different subtypes of hypertension in different ethnicities in Xinjiang, a northwestern province in China.MethodsA total of 14,618 participants (5,757 Hans, 4,767 Uygurs, and 4,094 Kazakhs) from 26 villages of seven cities in Xinjiang were randomly selected from the Cardiovascular Risk Survey conducted during 2007 and 2010. A standard questionnaire, a physical examination and biochemical tests were employed.ResultsThe mean common carotid intima-media thickness (CIMT) for the 14,618 participants was 0.86±0.003 mm. The CIMT gradually increased with age. Men (0.92±0.005 mm) had a higher CIMT than women (0.81±0.004 mm). The Uygur participants (0.82±0.006 mm) had a lower CIMT than the Han (0.88±0.005 mm) and Kazakh participants (0.88±0.005 mm). The overall prevalences of carotid intimal thickening and carotid plaques were 12.4% and 9.7%, respectively. The prevalence of CIMT varied for the different subtypes of hypertension. Multivariate logistic regression analysis showed different risk factors for abnormal CIMT in different ethnicities. The associations between abnormal CIMT and the different subtypes of hypertension within different ethnic backgrounds were also different. The risk factors for abnormal CIMT included systolic-diastolic hypertension (SDH) in Han participants (OR: 1.323, 95% CI: 1.100-1.590), SDH (OR: 1.426, 95% CI: 1.160-1.753) and isolated-systolic hypertension (ISH) (OR: 1.844, 95% CI: 1.470-2.313) in Uygur participants, and isolated-diastolic hypertension (IDH) (OR: 1.536, 95% CI: 1.170-2.016) in Kazakh participants.ConclusionThere was an ethnic difference in the prevalence of abnormal CIMT in Xinjiang, a northwestern province in China. The associations between abnormal CIMT and the subtypes of hypertension varied among the different ethnic groups. Among the studied populations, Han participants with SDH, Uygur participants with SDH and ISH, and Kazakh with IDH were more likely to suffer carotid atherosclerosis than those with other subtypes of hypertension. Participants with different ethnic backgrounds had different sets of risk factors for abnormal CIMT.
