Association of glucocorticoid receptor gene polymorphism and occupational stress with hypertension in desert petroleum workers in Xinjiang, China.

ABSTRACT: BACKGROUND:The aim of this study was to investigate the occupational stress and hypertension in desert petroleum workers in Xinjiang, and to analyze the association of occupational stress and glucocorticoid receptor (GR) gene polymorphism with the presence of hypertension. METHODS:Using cluster sampling, 1280 desert petroleum workers of 3 petroleum fields in Xinjiang Karamay were randomly selected as the target group for this study. According to the inclusion criteria, a total of 1080 workers were included as the baseline for this study. We followed these workers for 2 years to investigate their occupational stress and hypertension. The polymorphism of GR gene was detected by polymerase chain reaction-restriction fragment length polymorphism. We applied appropriate statistical methods to analyze the association of occupational stress and glucocorticoid receptor (GR) gene polymorphism with the presence of hypertension. RESULTS:After 2 years of follow-up, there were 995 desert petroleum workers in the queue. The study showed that the incidence of hypertension in desert petroleum workers were 19.4%. Compared with the baseline data, the level of occupational stress increased, and with the increase of occupational stress, the incidence of hypertension was gradually increasing. A positive relationship was observed in the GR BCL1 gene polymorphisms and hypertension. Relative to the CC genotype, carries of the GG genotype had a significantly higher risk of hypertension (OR?=?2.830). With the combination of genotype CG and GG, carries of CG and GG increased the risk of hypertension (adjusted OR?=?2.238, 95%CI:1.104-4.940). There was no significant association between GR G678S gene polymorphisms and hypertension. CONCLUSION:GR gene polymorphism and occupational stress of desert petroleum workers were important risk factors for hypertension.

Project description:BackgroundTo explore the relationship between lipid accumulation product (LAP) and visceral adiposity index (VAI) and hypertension in oil workers and to evaluate the predictive value of hypertension by gender.MethodsA sample of 2,312 workers aged 18-60 years old with more than one year of service were selected by a whole-group random sampling method in six oil field bases in Karamay City, Xinjiang. Logistic regression combined with restricted cubic spline model was used to analyze the risk of hypertension in different LAP and VAI. The receiver operator characteristic curve (ROC) with different sex LAP and VAI predicting the risk of hypertension were drawn.Results(1) There were significant differences in age, smoking, alcohol consumption, hypertension, BMI, WC, WHtR, SBP, DBP, TC, TG, HDL, LDL, FPG and Scr among different gender groups (P < 0.001).The prevalence of hypertension was 10.1%, with 13.9% in men and 3.6% in women. The prevalence of hypertension with different individual characteristics was statistically significant (P < 0.05). (2) Lipid accumulation product and visceral adiposity index were positively associated with hypertension (P < 0.001). The risk of hypertension may increase with the increase of lipid accumulation product and visceral adiposity index. After adjusting for age, sex, BMI, Scr, FPG and other factors, the risk of hypertension in the fourth quartile was (OR = 5.69, 95% CI [2.72-11.8]) and (OR = 3.56, 95% CI [2.03-6.23]) compared with the first quartile of lipid accumulation product and visceral adiposity index. (3) ROC results showed: AUC values of 0.658 (95% CI [0.619-0.696]), 0.614 (95% CI [0.574-0.654]), 0.661 (95% CI [0.620-0.703]) and critical values of 43.25, 1.58, 0.13 for LAP, VAI and combined indicators in men; the AUC values of LAP, VAI and combined indicators for women were 0.787 (95% CI [0.710-0.865]), 0.732 (95% CI [0.640-0.825]), 0.792 (95% CI [0.719-0.864]) and the critical values were 35.73, 1.76 and 0.03. Restricted cubic splines showed a nonlinear dose-response relationship between LAP, VAI, and risk of hypertension prevalence (P < 0.01 for overall trend and P < 0.01 for nonlinearity).ConclusionsLipid accumulation product and visceral adiposity index may be risk factors for hypertension in oil workers. LAP and VAI have certain predictive value for hypertension.

Project description:ObjectiveThe aim of this study is to explore sleep status and hypertension among oil workers in Xinjiang, China. It may provide new ideas and basis for the precise prevention and treatment of hypertension in occupational population.MethodsSleep status and hypertension were investigated in 3,040 workers by a multi-stage cluster sampling method in six oil field bases in Karamay City, Xinjiang. The Pittsburgh Sleep Quality Index was used to evaluate the sleep status of workers. Logistic regression was used to analyze the relationship between sleep duration and sleep quality, and hypertension. Stratified analysis was also performed.ResultsOur results show: 1. Insufficient sleep duration (OR = 1.51, 95% CI [1.19-1.90]) and poor sleep quality (OR = 1.78, 95% CI [1.33-2.38] were positively associated with hypertension. 2. Stratified analysis indicated insufficient sleep duration was associated with increased risk of hypertension in females (OR = 1.54, 95% CI [1.16-2.04]) than males (OR = 1.49, 95% CI [1.00-2.23]), and the risk of hypertension in the group <30 years old (OR = 9.03, 95% CI [2.32-35.15]) was higher than that in the group of 30-45 years old (OR = 1.59, 95% CI [1.14-2.20]). However, in the group > 45 years old, sleeping > 8 h was associated with increased risk of hypertension (OR = 3.36, 95% CI [1.42-7.91]). Oil workers doing shift work had a higher risk of hypertension (OR = 1.55, 95% CI [1.16-2.07]) to no shift work (OR = 1.48, 95% CI [1.02-2.15]). The risk of hypertension in the group with < 10 years of service (OR = 4.08, 95% CI [1.92-8.83]) was higher than that in the group with length of service of 10-20 years (OR = 2.79, 95% CI [1.59-4.86]). Poor sleep quality was associated with risk for hypertension in females (OR = 1.78, 95% CI [1.26-2.49]), those doing shift work (OR = 1.70, 95% CI [1.17-2.47]), those with length of service of > 20 years (OR = 1.64, 95% CI [1.18-2.27]). The risk of hypertension in the group 30-45 years old is higher than that in the group > 45 years old (OR 30-45 years old = 1.71, 95% CI [1.10-2.66]; OR > 45 years old = 1.60, 95% CI [1.09-2.34]).ConclusionInsufficient sleep duration and poor sleep quality are the potential factors affecting hypertension in Xinjiang oil workers.

Project description:Background: This study investigated the relationship between occupational stress and the mental health of people working in oil fields in the arid desert environment of Xinjiang, and revealed the causal relationship between occupational stress and psychological disorders, while furthermore exploring the relationship between psychological disorders and genetic levels. Methods: The participants of this study included oil field company workers from the Xinjiang Petroleum Administration of Karamay City, Xinjiang, who underwent occupational health examinations. The Occupational Stress Inventory Revised Edition (OSI-R) was used to measure the occupational stress of the oil workers. The mental health status of oil workers was evaluated using the Symptoms Checklist-90. Results: Occupational tasks: The total scores of the personal strain and mental health questionnaires were positively correlated with somatization, obsessive-compulsive symptoms, interpersonal sensitivity, depression, anxiety, hostility, terror, paranoia, and psychosis (P < 0.05). Individual coping resources and the mental health total score was negatively correlated with somatization, obsessive-compulsive symptoms, interpersonal sensitivity, anxiety, hostility, terror, paranoia, and psychosis. The following factors were identified as mental health risk factors: female gender; age 45 and above (relative to ≤30 years old); high scores on the personal strain questionnaire; occupational stress; external effort; internal investment; and high effort-low return. The following factors were identified as protective factors for mental health: Han nationality; oil transportation (relative to drilling); individual resilience; and work returns. In respect to the abnormal psychological group and the normal psychological group, statistically significant differences were found in the distribution of genotypes and allele frequencies at the rs1800497 locus (P < 0.05). The depression and paranoia scores observed between different genotype groups at the rs1800497 locus were statistically significant (P < 0.05). Conclusions: This study shows that occupational stress and the D2 dopamine receptor (DRD2) gene have an impact on the mental health of oil field workers in the arid desert environment of Xinjiang. Effort-reward imbalance and occupational stress were identified as risk factors for mental health, while rewards for work were protective factors. Higher levels of occupational stress may lead to depression and other psychological disorders, adversely affecting mental health. In oil field operators in the arid desert environment of Xinjiang, the AA genotype of the DRD2 gene in the rs1800497 locus was identified as a genotype specific to susceptibility to mental health problems, and a correlation was found between the A allele and an increased risk of psychological problems. Therefore, it is necessary to devise relevant measures to alleviate occupational stress among oil workers and increase their job rewards, so as to improve their mental health.

Project description:BACKGROUND:Cardiovascular benefits by reversing environmental risks factors for essential hypertension (EH) and dyslipidemia could be weaken by high genetic risk. We investigated possible associations between ACE2 polymorphisms and dyslipidemia in patients with EH. METHODS:Four hundred and two hypertensive patients were enrolled in an EH group and 233 normotensive individuals were enrolled as control group from the Xinjiang region of China. Fourteen ACE2 polymorphisms were genotyped by Matrix-assisted laser desorption ionization time-of-flight mass spectrometry. RESULTS:Participants carrying T allele (TT?+?CT) of rs2074192 (P?=?0.006), rs4646155 (P?=?0.030) and rs4646188 (P?<?0.001), C allele (CT?+?CT or CC?+?CG) of rs4240157 (P?=?0.012), rs4830542 (P?=?0.020) and rs879922 (P?<?0.001) and TT genotype of rs2106809 (P?=?0.012) were associated with EH. Meanwhile,ACE2 SNPs also exhibited association with dyslipidemia but exhibited obvious heterogeneity. rs1978124 (TT?+?CT, P?=?0.009), rs2106809 (TT, P?=?0.045), rs233575 (CC?+?CT, P?=?0.018), rs4646188 (CC, P?=?0.011) and rs879922 (CC?+?CG, P?=?0.003) were association with increased LDL-C (?1.8 mmol/L). rs2106809 (CC?+?CT, P?<?0.001), rs2285666(TT?+?CT, P?=?0.017), rs4646142(CC?+?CG, P?=?0.044), rs4646155(TT?+?CT, P?<?0.001) and rs4646188(TT?+?CT, P?=?0.033) were association with decreased HDL-C (<?1.0 mmol/L). rs2074192 (TT?+?CT, P?=?0.012), rs4240157 (CC?+?CT, P?=?0.027), rs4646156 (AA+AT, P?=?0.007), rs4646188 (TT?+?CT, P?=?0.005), rs4830542 (CC?+?CT, P?=?0.047) and rs879922 (CC?+?CG, P?=?0.001) were association with increased TC (?5.2 mmol/L). rs2106809 (P?=?0.034) and rs4646188 (P?=?0.013) were associated with hypertriglyceridemia. Further, ischemic stroke was more prevalent with rs4240157 (CC?+?CT, P?=?0.043), rs4646188 (CC?+?CT, P?=?0.013) and rs4830542 (CC?+?CT, P?=?0.037). In addition, rs2048683 and rs6632677 were not association with EH, dyslipidemia and ischemic stroke. CONCLUSION:The ACE2 rs4646188 variant may be a potential and optimal genetic susceptibility marker for EH, dyslipidemia and its related ischemic stroke.

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:IntroductionAn increasing number of original studies suggested that occupational noise exposure might be associated with the risk of hypertension, but the results remain inconsistent and inconclusive. In addition, the attributable fraction (AF) of occupational noise exposure has not been well quantified. We aimed to conduct a large-scale occupational population-based study to comprehensively investigate the relationship between occupational noise exposure and blood pressure and different hypertension subtypes and to estimate the AF for hypertension burden attributable to occupational noise exposure.MethodsA total of 715,135 workers aged 18-60 years were included in this study based on the Key Occupational Diseases Surveillance Project of Guangdong in 2020. Multiple linear regression was performed to explore the relationships of occupational noise exposure status, the combination of occupational noise exposure and binaural high frequency threshold on average (BHFTA) with systolic and diastolic blood pressure (SBP, DBP). Multivariable logistic regression was used to examine the relationshipassociation between occupational noise exposure status, occupational noise exposure combined with BHFTA and hypertension. Furthermore, the attributable risk (AR) was calculated to estimate the hypertension burden attributed to occupational exposure to noise.ResultsThe prevalence of hypertension among occupational noise-exposed participants was 13·7%. SBP and DBP were both significantly associated with the occupational noise exposure status and classification of occupational noise exposure combined with BHFTA in the crude and adjusted models (all P < 0·0001). Compared with workers without occupational noise exposure, the risk of hypertension was 50% greater among those exposed to occupational noise in the adjusted model (95% CI 1·42-1·58). For participants of occupational noise exposed with BHFTA normal, and occupational noise exposed with BHFTA elevated, the corresponding risks of hypertension were 48% (1·41-1·56) and 56% (1·46-1·63) greater than those of occupational noise non-exposed with BHFTA normal, respectively. A similar association was found in isolated systolic hypertension (ISH) and prehypertension. Subgroup analysis by sex and age showed that the positive associations between occupational noise exposure and hypertension remained statistically significant across all subgroups (all P < 0.001). Significant interactions between occupational noise status, classification of occupational noise exposure combined with BHFTA, and age in relation to hypertension risk were identified (all P for interaction < 0.001). The associations of occupational noise status, classification of occupational noise exposure combined with BHFTA and hypertension were most pronounced in the 18-29 age groups. The AR% of occupational noise exposure for hypertension was 28·05% in the final adjusted model.ConclusionsOccupational noise exposure was positively associated with blood pressure levels and the prevalence of hypertension, ISH, and prehypertension in a large occupational population-based study. A significantly increased risk of hypertension was found even in individuals with normal BHFTA exposed to occupational noise, with a further elevated risk observed in those with elevated BHFTA. Our findings provide epidemiological evidence for key groups associated with occupational noise exposure and hypertension, and more than one-fourth of hypertension cases would have been prevented by avoiding occupational noise exposure.
