广西城市社区居民高尿酸血症流行病学调查及其与慢性肾脏病的关系

目的 通过社区人群筛查了解广西城市原住民中高尿酸血症(HUA)的患病率及其与慢性肾脏病(CKD)的关系,并探讨影响HUA肾损害的风险因素.方法 选择桂林市城区原住居民集中的象山社区,对18～75岁居民(n=6 273)采取横断面进行筛查.收集空腹血及晨尿进行血糖、肾功能、血脂、胰岛素和尿蛋白等检测,同时进行问卷调查和体格检查.结果 社区居民中HUA总患病率为23.5%,其中男性HUA患病率显著高于女性(28.4%对19.7%,P＜0.01).社区居民中CKD患病率为21.6%,其中男性居民CKD患病率较女性显著增高(24.9%对19.0%,P＜0.01).在HUA人群中CKD检出率显著高于尿酸正常人群(30.4%对18.9%,P＜0.01).男性HUA人群CKD检出率显著高于同性别正常血尿酸人群(34.3%对21.2%,P＜0.01),也显著高于女性HUA人群(25.9%,P＜0.01).Logistic回归分析发现,CKD仅与收缩压、低密度脂蛋白胆固醇和血糖水平独立相关(P＜0.01).结论 广西城市社区居民中HUA患病率显著增加,与CKD患病率增高有关,且血尿酸轻度增高即增加CKD患病率.

Abstract：

Objective To detect the prevalence of hyperuricemia and its relationship to chronic kidney disease(CKD) in the residents of Guangxi, and to discuss the risk factors for the hyperuricemia associated renal damage. Methods The residents aged 18-75 years old(n=6 273) in Xiangshan community,Guilin, were screened by means of cross-sectional study. Blood pressure was measured at 8:00-9:00.Fasting blood and urine samples were collected to determine blood glucose, lipid, insulin, creatinine, and urine albumin. Results The prevalence of hyperuricemia in the community residents was 23.5% in all cohort, being significantly higher in male residents than in female(28.4% vs 19.7%,P＜0.01). The prevalence of CKD was 21.6% in all cohort, and was 24.9% in males and 19.0% in females(P＜0.01). The prevalence of CKD was 30.4% and 18.9% respectively in residents with and without hyperuricemia(P＜0.01).The prevalence of CKD in males with hyperuricemia(34.3%) was significantly higher than in males without hyperuricemia(21.2%) and females with hyperuricemia(25.9%, all P＜0.01). CKD was only positively related to low-density lipoprotein cholesterol, blood glucose, and systolic blood pressure shown by logistic regression analysis. Conclusions The prevalence of hyperuricemia markedly increases in the urban residents, which contribute to the raised prevalence of CKD. Slightly elevated blood uric acid level is associated with raised prevalence of CKD.

Abstract：

Objective To determinate the risk factors of gout in patients with hyperuricemia.Methods Patients detected with hyperuricemia both in epidemiological survey of Shandong coastal areas in 2004 and in health examination of our hospital were followed up for three years to observe the incidence of gout, relationship of diet and gout, and changes of biochemical indicators.Results During 3 years, 102 patients (19%) out of 536 patients with hyperuricemia developed gout. Age(OR=1.046, P＜0.05), serum uric acid(OR=1.021, P＜0.05), fasting plasma glucose(OR=1.021, P＜0.05), triglyceride(OR=1.008, P＜0.05), tony crab intake ( OR=5.992, P＜0.05),and beer intake(OR=1.012, P＜0.05) were the risk factors of gout attack in patients with hyperuricemia.Conclusions Excess intake of tony crab and beer resulting in fluctuation of serum uric acid is the main risk factor of gout in patients with hyperuricemia. Correcting metabolic disorder of glucose and lipid, reducing the intake of high-purine food, and controlling the level of serum uric acid are the measures to reduce gout attack.     

Recent Trends of Epidemic Hypertension in Guangdong Province

Hypertension survey was carriedout in Guangdong Province in 1991, according to a national sampling survey program. 42 899 urban and rural men and women aged ≥15 were involved in the survey. The results revealed that the standardized prevalence rate of hypertension was 8. 99% (definite 4. 24% , borderline 4. 75% ) . It was higher in men than in women, in urban than in rural samples. Compared with the survey in 1979, the prevalence rate increased by 90% and the curve of aged - prevalence rates shifted leftward. This article also discuss the possible factors that lead to the increase of hypertension.     

Prevalence of gastroesophageal reflux symptoms in a large unselected general population in Japan

AIM：To examine the prevalence of gastroesophageal reflux disease （GERD） symptoms in a large unselected general population in Japan.
METHODS： In Japan, mature adults are offered regular check-ups for the prevention of gastric cancer. A notice was sent by mail to all inhabitants aged 〉 40 years. A total of 160 983 Japanese （60 774 male, 100 209 female; mean age 61.9 years） who underwent a stomach check up were enrolled in this study. In addition, from these 160 983 subjects, we randomly selected a total of 82 894 （34 275 male, 48 619 female; mean age 62.4 years） to evaluate the prevalence of abdominal pain. The respective subjects were prospectively asked to complete questionnaires concerning the symptoms of heartburn, dysphagia, and abdominal pain for a 1 mo period.
RESULTS： The respective prevalences of the symptoms in males and females were： heartburn, 15.8% vs 20.7%; dysphagia, 5.4% vs 7.8%; and abdominal pain, 6.6% vs 9.6%. Among these symptoms, heartburn was significantly high compared with the other symptoms, and the prevalence of heartburn was significantly more frequent in females than in males in the 60-89-year agegroup. Dysphagia was also significantly more frequent in female patients.
CONCLUSION： The prevalence of typical GERD symptoms （heartburn） was high, at about 20% of the Japan population, and the frequency was especially high in females in the 60-89 year age group.     

Prevalence of nonalcoholic fatty liver among administrative officers in Shanghai： an epidemiological survey

AIM: To determine the prevalence of nonalcoholic fatty liver in a specific population in Shanghai by an epidemiological survey, and to analyze risk factors of fatty liver.METHODS: Total 4009 administrative officers who denied regular alcohol drinking participated in the survey, and underwent physical examination and laboratory tests. The important parameters were body mass index (BMI), waist hip circumferences ratio (WHR) and levels of serum lipids.Diagnosis of fatty liver was based on established real-time ultrasonographic criteria, the presence of an ultrasonographic pattern consistent with “bright liver”, with evident ultrasonographic contrast between hepatic and renal parenchyma, vessel blurring, and narrowing of the lumen of the hepatic veins. Analysis of data was performed through SPSS for Windows statistical package.RESULTS: The overall prevalence of fatty liver was 12.9%,15.8% in males and 7.5% in females, and the prevalence of fatty liver in males younger than 50 years old, was significantly higher (13.3%) than that of in females (2.7%).But the difference between the sexes became less significant in people older than 50 years (19.1% vs 18.1%). Theprevalence of fatty liver was increased with age; this was markedly presented in females younger than 50 years.Multiple variant regression analysis demonstrated that the prevalence of fatty liver was positively correlated to several risk factors, including male, aging (>50yr), hyperlipidemia,impaired glucose tolerance/diabetes mellitus, hypertension and overweight/obesity.CONCLUSION: There is a high prevalence of nonalcoholic fatty liver among certain population in Shanghai, to which overweight and hyperlipidemia are closely relevant.     

Gender differences,outcomes and trends among nonagenarian with atrial fibrillation:insight from National Inpatient Sample database

BACKGROUND Nonagenarians(NG),individuals aged≥90 years,constitute an increasing proportion of hospitalizations presenting with atrial fibrillation(AF).However,not much is known about demographics,clinical outcomes,and trends of hospitalizations.Therefore,we analyzed data about hospitalizations and clinical outcomes among NGs with AF over ten years from 2005 to 2014 using a publically available database,the National Inpatient Sample.METHODS All hospitalizations and major outcomes of subjects≥90 years with a primary diagnosis of AF(ICD-9-CM code 427.31)over a ten-year period were assessed in this study by multivariate logistic regression analysis.RESULTS There were more females than males(176,268 females,51,384 males)in this analysis.The number of hospitalizations for AF among NG increased by 50%(17,295 in 2005 to 25,830 in 2014).Males were more likely to undergo cardioversion(6.14%of males vs.5.06%of females,P<0.0001).Over this period,in-hospital mortality declined from 3.21%in 2005 to 2.38%in 2014(P=0.0041),with higher in-hospital mortality in males(3.23%in males vs.2.76%in females,P=0.0138),mean length of hospitalization decreased from 4.53 days to 4.13 days(P<0.0001),the prevalence of congestive heart failure fell from 0.48%to 0.23%(P=0.0257),and the use of anticoagulation increased from 6.09%to 14.54%(P<0.0001).In a multivariate analysis,hospital admission on the weekend,Elixhauser comorbidity index,CHA2DS2VASc score,acute respiratory failure,and the length of hospital stay were associated with a higher risk of in-hospital mortality.CONCLUSIONS From 2005 to 2014,AF-related hospitalizations among NGs increased,more so in in females population,mortality trends improved,rates of anticoagulation increased,and cardioversions increased.Despite the decreasing trend of in-hospital mortality since 2005,the relatively high mortality rate in males warrants further studies.     

Epidemiology and transmission of hepatitis B and C viruses in Kazakhstan

AIM: To investigate the epidemiology of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection in the two major ethnic groups in Kazakhstan. METHODS: A cross-sectional prospective study of HBV and HCV seroprevalence was performed among individuals born in Kazakhstan with no history of chronic hepatitis or liver disease. RESULTS: There were 290 volunteers (140 Russians and 150 Kazakhs) aged 10 to 64 years, males accounted for 46%. Active HBV infection (HBsAg positive) was present in 3.8%, anti-HBc in 30%. The prevalence was similar in females and males (33% vs 25%) (P = 0.18). The prevalence of anti-HBc increased from 19% in 10-29 years old volunteers to 53% in 50-years and older volunteers. The prevalence of HBV infection was higher in married than in single adults (38% vs 26%, respectively) (P = 0.2) and more common in Kazakhs (35%) than in Russians (24%) (P = 0.07). HCV infection was present in 9 subjects (3.2%), 5 of them also were positive for anti-HBc in the absence of HBsAg. CONCLUSION: The frequency of active HBV infection (3.8%) coupled with a high prevalence of HBV exposure in those > 50 years of age increases with age, which suggests that horizontal transmission likely relates tothe use of contaminated needles. The low prevalence of HCV infection suggests that HBV and HCV are acquired differently in this group of subjects.     

A community-based epidemiological study of elevated serum alanine aminotransferase levels in Kinmen, Taiwan

AIM: To explore any gender-related differences in prevalence of and condition-associated factors related to an elevated serum alanine aminotransferase (ALT) level amongst residents of Kinmen, Taiwan. METHODS: A total of 11 898 of a potential 20 112 regional residents aged 30 years or more completed a related questionnaire that was carried out by the Yang-Ming Crusade between 1991 and 1994 inclusively, with blood samples being collected by public nurses. The overall questionnaire response rate was 59.3% (52.4% for males and 66.0% for females). RESULTS: The prevalence of an elevated serum ALT level for this sub-population was found to be 7.2%, the prevalence revealing a statistically significant decrease with increasing population age (P<0.0001). Males exhibited a greater prevalence of elevated serum ALT level than did females (9.4% vs 5.3%, P<0.0001). Using multiple logistic regression analysis, in addition to male gender, a younger age, greater waist circumference, presence of type-2 diabetes and hyperuricemia were the significant factors associated with an elevated serum ALT level for both males and females. Gender-related differences as regards associated factors were also revealed. For males, obesity was significantly related to an elevated serum ALT level (OR = 1.28, 95%CI: 1.00-1.66) but this was not so for females (OR = 1.09, 95%CI: 0.84-1.42). Hypertriglyceridemia (OR = 1.80, 95%CI: 1.36-2.39) and hyperuricemia (OR = 1.61, 95%CI: 1.03-2.52) were significantly related to elevated serum ALT levels only for females. CONCLUSION: Several gender-related differences were noted pertaining to the prevalence of and relationship between obesity, hypertriglyceridemia and hyperuricemia and elevated serum ALT level in the present study.     

Changing patterns of hepatitis A prevalence within the Saudi population over the last 18 years

AIM： To determine the seroprevalence of Hepatitis A （HAV） amongst Saudi children and compare it with previously reported prevalence data from the same population. METHODS： A total of 1357 students were randomly selected between the ages of 16 and 18 years （689 males and 668 females） from three different regions of Saudi Arabia （Madinah, AI-Qaseem, and Aseer） and tested for anti-HAV-IgG.RESULTS： The overall prevalence of anti-HAV-IgG among the study population was 18.6%. There was no difference between males and females but there was a significant difference in the seroprevalence （P = 0.0001） between the three different regions, with Madinah region showing the highest prevalence （27.4%）. When classified according to socioeconomic status, lower class students had a prevalence of 36.6%, lower middle class 16.6%, upper middle class 9.6%, and upper class 5.9% （P = 0.0001）. Comparing the current study results with those of previous studies in 1989 and 1997 involving the same population, there was a marked reduction in the overall prevalence of HAV from 52% in 1989, to 25% in 1997, to 18.6% in 2008 （P 〈 0.0001）.CONCLUSION： Over the last 18 years, there has been a marked decline in the prevalence of HAV in Saudi children and adolescents. The current low prevalence rates call for strict adherence to vaccination policies in high-risk patients and raises the question of a universal HAV vaccination program.     

Specific serum immunoglobulin G to Hpylori and CagA in healthy children and adults （south-east of Iran）

AIM: To evaluate the serologic IgG response to H pylori and CagA across age groups and in healthy children and adults. METHODS: Totally, 386 children aged 1-15 years and 200 adults aged 20-60 years, were enrolled to study. The serum samples of participant were tested for presence of anti-H pylori and anti-CagA IgG by using ELISA method. RESULTS: The seroprevalence of H pylori in adults was signif icantly higher than that observed in children (67.5/ vs 46.6/; P < 0.000003). In children, the seropositivity rate in males (51.9/) was signifi cantly (P < 0.05) higher than that observed in females (41.7/). The prevalence of serum anti-CagA antibody was 72.8/ and 67.4/ in infected children and adults, respectively. The mean titer of serum anti-CagA antibodies was significantly higher among children in comparison to adults (64.1 Uarb/mL vs 30.7; P < 0.03). In infected children and adults the prevalence of serum anti-CagA antibody was higher in males compared to females (78.4/ vs 66.3/; P = 0.07 and 75.6/ vs 54.71/; P < 0.04, respectively). The age-specific prevalence of anti-H pylori and anti-CagA antibody (in infected subjects) was 37.6/ and 59.57/ at age 1-5 years, 46.9/ and 75/ at age 6-10 years, 54.9/ and 79.45/ at age 11-15, 59.01/ and 83.33/ at age 20-30 years, 66.6/ and 60.52/ at age 31-40 years, 73.46/ and 63.88/ at age 41-50 years and 75.75/ and 60/ at age 51-60 years with mean titer of anti-CagA antibody of 75.94, 63.32, 57.11, 52.06, 23.62, 21.52 and 21.80 Uarb/mL, respectively. There was significant difference between mean serum anti-CagA antibody in age subgroups (P < 0.001). CONCLUSION: These results showed that anti-H pylori and anti-CagA antibodies were common in the children and adults. The H pylori-specifi c antibodies influenced by age and sex of subjects. Moreover, it seems that malesare more susceptible to infection with CagA+ strains compared to females. The seroprevalence of anti-CagA antibody was increased with age, up to 30 years and then decreased. It was also found that the magnitude of the IgG response to CagA decreased with advanced age.     

Recent advances in the epidemiology of gout

Gout remains among the most common of all inflammatory arthridities with an incidence that appears to have risen. Evidence is accumulating to support lifestyle and dietary factors, such as heavy consumption of beer and liquor as well as diets rich in meats and seafood as important gout risk factors. There is also a renewed interest in important associations between gout and other comorbidities like hypertension and cardiovascular disease. The importance of hyperuricemia on health considerations beyond the musculoskeletal system is an area worthy of even more study.

Hyperuricemia and gout in Taiwan: results from the Nutritional and Health Survey in Taiwan (1993-96)

OBJECTIVE: To evaluate the prevalence of hyperuricemia in Taiwan. METHODS: A multi-stage stratified sampling scheme was used in Nutrition and Health Survey, which was conducted in Taiwan between 1993 and 96. Complete biochemical and questionnaire data for 2754 males and 2953 females aged 4 years and older were included in the analysis. The colorimetric enzymatic method was used to measure plasma uric acid in fasting blood samples. Information on self-reported, physician-diagnosed gout was also obtained. RESULTS: The uric acid values of males were found to reach a peak between the ages of 13 and 18 and decrease slightly after 18. The uric acid values of females were stable before the age of 18, decreasing slightly between 19 and 44 years, and increasing in the mid to older age groups (> or = 45 years). Twenty-six percent of adult males (> or = 19 years) and 22% of older males (> or = 45 years) either had hyperuricemia (serum uric acid > 458.0 microM or 7.7 mg/dl) or were taking medication for it. Seventeen percent of adult females and 23% of older females either had hyperuricemia (serum uric acid > 392.57 microM or 6.6 mg/dl) or were taking medication for it. Both adult males and females in mountainous areas, who were primarily aboriginal, had the highest prevalence of hyperuricemia (> 50%) among the 7 survey areas. Mean body mass index (BMI), alcohol consumption, and prevalence of gout were among the highest in mountainous people compared to all included in the study. Multivariate analysis showed that mountainous area, age and BMI are important factors associated with hyperuricemia in males, whereas mountainous area, Class II townships, and BMI are the factors associated with hyperuricemia in females. CONCLUSIONS: We found a high prevalence of hyperuricemia in Han Chinese in Taiwan despite a lack both of obesity and high alcohol consumption. Mountainous people (mainly aborigines) in Taiwan have an even higher prevalence of hyperuricemia, which cannot be completely explained by obesity and alcohol consumption. Genetic components and other environmental factors may have contributed to this pattern of hyperuricemia.     

Gout: epidemiology and lifestyle choices

PURPOSE OF REVIEW: Recent scientific data serve to illuminate the links between dietary and other factors and the incidence of gout. This review summarizes recent literature about the prevalence and incidence of gout as well as risk factors for gout. RECENT FINDINGS: Epidemiologic studies suggest that the overall disease burden of gout is substantial and growing. Gout seems to be relatively common not only in men but also in older women. A recent large prospective study investigated several purported dietary factors for gout and confirmed some of the long-standing suspicions (red meats, seafood, beer, and liquor), exonerated others (total protein, wine, and purine-rich vegetables), and also identified potentially new protective factors (dairy products). A study based on the Third National Health and Nutrition Examination Survey suggested that these factors affect serum uric acid levels parallel to the direction of risk of gout. In addition, adiposity, weight gain, hypertension, and diuretics were all found to be independent risk factors for incident gout, whereas weight loss was found to be protective. SUMMARY: The disease burden of gout remains substantial and may be increasing. Some of the recently confirmed lifestyle factors may explain the increasing incidence of gout. The public health implications of dietary and lifestyle recommendations should take into account other associated health benefits and risks, because many of these factors have health effects beyond their influence on gout.

目的调查北京万寿路地区年龄≥60岁老年人群高血压的患病水平及相关因素。方法选择2009年9月～2010年6月北京万寿路地区5个社区的2071例年龄≥60岁老年人的健康状况调查数据,运用横断面设计的统计学方法进行分析。结果高血压患病率71.6%,男性68.1%,女性74.0%,标准化患病率70.7%,男性67.6%,女性73.4%。调整了年龄、性别、文化程度、婚姻状况、退休前职业等因素后,多因素分析显示,TG、空腹血糖、腰围、超重、肥胖、高血压家族史为高血压的危险因素,HDL-C和体重过低为高血压的保护因素。结论该地区老年人群高血压患病水平高,其发病与多种因素有关,而不良的生活方式可能是高血压发生的重要影响因素。     

Potential unmet need for gout diagnosis and treatment: capture-recapture analysis of a national administrative dataset

Objective: To estimate the degree of undercount of people diagnosed with gout in administrative datasets using capture-recapture methods. Methods: Hospitalization and drug dispensing claims (allopurinol or colchicine) data for all Aotearoa New Zealand were used to estimate the prevalence of gout in 2009 (n = 4 295 296). As a comparison, we calculated gout prevalence using a large primary care dataset using general practitioner diagnosis and prescribing records (n = 555 313). For each of these datasets, we estimated the undercount through capture-recapture analysis using a Poisson regression model. A two-list model was used, which included covariates such as age, gender, ethnic groups and New Zealand deprivation quintiles. Results: The crude prevalence of diagnosed gout in the Aotearoa New Zealand population aged ≥20 years was 3.75%. The covariate-adjusted capture-recapture estimate of those not recorded but likely to have gout was 0.92%, giving an overall estimated prevalence of 4.67% (95% CI 4.49, 4.90%) for the population aged ≥20 years. This amounts to 80% of people with gout being identified by the algorithm for the Aotearoa New Zealand data-that is being recorded in either lists of dispensing of allopurinol or colchicine or hospital discharge. After capture-recapture, gout prevalence for all males aged ≥20 years was 7.3% and in older (≥65 years) Māori and Pacific men was >30%. Conclusion: Capture-recapture analysis of administrative datasets provides a readily available method for estimating an aspect of unmet need in the population-in this instance potentially 20% of those with gout not being identified and treated specifically for this condition.
