Investigation on the prevalence of metabolic diseases among residentsin Moyu County / 预防医学

Objective@#To investigate the prevalence of metabolic diseases among residents in Moyu County, Hotan Prefecture, Xinjiang Uygur Autonomous Region, so as to provide the evidence for developing the control strategy for metabolic diseases.@*Methods@#The demographic features, laboratory examinations and B-mode ultrasonographic examinations of the liver and gall bladder were collected from residents at ages of 18 years and older in Moyu County through the hospital-based medical records system. The prevalence of metabolic diseases was estimated, including obesity, hypertension, diabetes, dyslipidemia and fatty liver, and the factors affecting the development of metabolic diseases were identified using a multinomial logistic regression model.@*Results@#Totally 281 803 residents were included in the study, including 129 549 men ( 49.97% ) and 152 254 women ( 54.03% ) and with a median age of 37.00 years ( interquartile range, 22.00 years ). The overall prevalence of metabolic diseases was 47.66%, and the prevalence rates of obesity, hypertension, dyslipidemia, fatty liver and diabetes were 25.72%, 24.77%, 12.30%, 12.05% and 5.49%, respectively, which appeared a tendency towards a rise with age ( χ2trend = 11 243.73, 14 086.41, 2 109.70, 6 631.22, and 2 011.15, all P<0.001 ). There were 73 811 residents suffering from one metabolic disease (26.19%), and 60 495 residents with two and more metabolic diseases ( 21.47% ). Multinomial logistic regression analysis showed that gender ( OR=0.870; 0.796 ), age ( OR: 1.703-8.701; 2.952-18.846 ), marital status ( OR: 1.397-1.845; 1.460-2.377 ) educational level ( OR: 0.891-0.937; 0.920-0.924 ), occupation ( OR: 1.177-1.270; 1.114-2.099), family history ( OR=1.136; 1.390), drinking frequency ( OR: 2.038; 1.395-2.574 ) and central obesity ( OR=3.448; 14.352 ) were factors affecting the development of one or more metabolic diseases.@*Conclusion@#The prevalence of metabolic diseases is high among residents in Moyu County. Men, the elderly, a low education level and unhealthy lifestyles may increase the risk of metabolic diseases.

Prevalence and clinical characteristic of Non-alcoholic fatty liver disease among Kirgiz adults in Xinjiang / 公共卫生与预防医学

Objective To explore the prevalence and characteristic of Non-alcoholic fatty liver disease (NAFLD) among the ethnic Kirghiz adult in Xinjiang Province. Methods The study was conducted based on the national health checkup in Xinjiang province during 2018. A total of 19 843 participants of Kirghiz adults in Aheqi County, Xinjiang Uygor Autonomous Region were selected for physical examination, questionnaires, blood biochemical indicators detection (FBG, TG, LDL-C, HDL-C, TC, ALT and AST) and abdominal ultrasonography. A total of 1 396 patients diagnosed with NAFLD by abdominal ultrasonography were selected as the case group, and 4 188 non-NAFLD subjects matched in age, sex and region were selected as the control group at a ratio of 1:3. The clinical characters and risk factors of NAFLD patients were analyzed. Results The overall prevalence of NALFD in Kirghiz adults was 7.0%, 7.8% in male, and 6.2% in female (standardized to 6.8%, 7.5%, and 6.0%, respectively). The prevalence in male was higher than that in female (P<0.01). The prevalence of NAFLD in the obesity, diabetes, and hypertension group was significantly increased, which was 19.0%, 20.6% and 18.5%, respectively. Body mass index (BMI), waist circumference (WC), triglycerides, AST (aspartate aminotransferase) and ALT (alanine transamilase) in the NAFLD group were all higher than those in the control group (all P < 0.01). In the NAFLD group, 17.2% had another one metabolic disorder and 62.0% had another two metabolic disorders. Logistic regression analysis showed that waist circumference (OR = 4.08, 95%CI = 3.04~5.10), FBG (OR = 3.76, 95%CI = 2.86~4.93) and BMI (OR = 3.32, 95%CI = 2.16~4.38) were the main independent risk factors for NAFLD. Literacy (OR = 0.42, 95%CI = 0.24~0.69) and physical activity (OR = 0.68, 95%CI = 0.45~0.96) were protective factors. Conclusion The prevalence of NAFLD in Kirgiz adults in Xinjiang is lower than the national average. More than half of NAFLD patients are comorbidity with at least two metabolic abnormalities. WC, FBG and BMI were the independent risk factors for NAFLD, however, literacy and physical activity were protective factors.

Association of GCKR gene rs780094 polymorphism with hyperuricemia in Uygur in Xinjiang / 中华内分泌代谢杂志

Objective To investigate the relationship between glucokinase regulator protein ( GCKR) gene polymorphism rs780094 and hyperuricemia in Uygur in Xinjiang. Methods A case-control study including 1 026 patients with hyperuricemia and 1 030 normal subjects was conducted. All the subjects were genotyped for GCKR gene rs780094 by Sequenom MassARRAY system. The results of rs780094 genotype and allele frequency between hyperuricemia group and control group were compared. The associations of different genotypes of rs780094 with blood pressure, blood lipid, and blood glucose were analyzed. Logistic regression analysis was used to analyse the relationship between polymorphism of rs780094 and hyperuricemia in Uygur in Xinjiang. Results The distributions of three genotypes(G/G, A/G, A/A) and two allele frequency (G and A) in GCKR rs780094 revealed statistical difference ( P<0. 05 ) between hyperuricemia group and control group. A tendency toward association with hyperuricemia was observed under dominant model(OR=1. 295, 95%CI 1. 078~1. 554,P=0. 006) and recessive model(OR=1. 284, 95% CI 1. 024 ~1. 611,P=0. 030). The levels of systolic blood pressure, diastolic blood pressure, and total cholesterol were lower in hyperuricemia group with GCKR gene rs780094 loci GG genotype than those with AA+AG genotype. After adjusting confounding factors which had significant difference in the single factor analysis, logistic regression analysis showed that rs780094 A/A and A/G might be risk factors of hyperuricemia in Uygur in Xinjiang (OR=1. 355,95% CI 1. 094 ~1. 679,P=0. 005). Conclusion The GCKR rs780094 is associated with hyperuricemia in Uygur in Xinjiang. The A/A and A/G genotype of the GCKR rs780094 may increase the risk of hyperuricemia.

The relationship of serum uric acid with risk factors of metabolic syndrome in Uygur in Xinjiang / 中华内分泌代谢杂志

Objective To analyze the distribution characteristics of blood uric acid and its relationship with the risk factors of metabolic syndrome in Uygur.Methods The questionnaire,anthropometric measurements,and biochemical detection were carried out in 4 428 healthy Uygur subjects in Xinjiang Urumqi and Kashi hospitals.Results (1) The prevalences of hyperuricemia and metabolic syndrome were 21.3 ％ and 8.2％,respectively.With the increased blood uric acid level,the incidences of coronary heart disease,hyperglycemia,hypertension,central obesity,and dyslipidemia were raised.Blood pressure,blood glucose,HbA1c,triglyceride,total cholesterol,apolipoprotein A,low density lipoprotein-cholesterol,body mass index (BMI),and waist to hip ratio (WHR) were increased with increased uric acid level,while high density lipoprotein-cholesterol was decreased.(2) The incidence of hyperuricemia was increased further when the number of metabolic syndrome components was accumulated (P＜0.01).With the increase of uric acid level,the prevalence of metablic syndrome gradually raised (P＜0.01).(3) Multiple logistic regression analysis showed that WHR (OR =7.639,95 ％ CI 1.744-33.466),coronary heart disease (OR =2.784,95 ％ CI 1.718-4.510),hyperuricemia (OR =2.155,95 ％ CI 1.457-3.188),smoking (OR =1.437,95％ CI 1.071-1.927),family history of metabolic diseases (OR =1.333,95％ CI 1.044-1.703),occupational pressure (OR =1.290,95 ％ CI1.021-1.631),and BMI (OR =1.146,95 ％ CI 1.112-1.181) were the risk factors of metabolic syndrome.Exercise (OR=0.472,95％ CI0.370-0.604) and low salt diet (OR=0.793,95％ CI0.662-0.949) were the protective factors.Conclusion Serum uric acid level is correlated with a variety of metabolic parameters.With the increased uric acid level,the risk of multiple metabolic abnormality was increased.Comprehensive prevention and control should be taken for the reduction of the risk factors and much attention should be paid to the adverse effects of hyperuricemia.
