Recognition and beliefs about treatment for mental disorders in mainland China: a systematic review and meta-analysis.

This review aimed to systematically investigate the Chinese public's ability to recognize specific mental disorders and their knowledge and beliefs about available treatments. Eight electronic databases were searched to identify quantitative studies examining recognition of depression, anxiety and/or schizophrenia, knowledge and beliefs about treatments, and/or correlates of each of the three constructs among the general population in China. Prevalence estimates were calculated for themes under each construct. Effect size r was computed for each relationship between an independent variable and one of the three constructs. A total of 65 studies (N = 174,253) were included in this review. Depression (25.4%), anxiety (18.2%) and schizophrenia (18.4%) had low recognition rates. More than 80% of people agreed that one should seek professional help for mental illnesses, but fewer than 40% were likely to use professional services for their own mental health issues. Regarding psychiatric medications, 57% of the respondents agreed that medications should be taken regularly, but more than 60% believed that they would be harmful. Gender, income, residential area, occupation, education and marital status were significantly associated with level of mental health knowledge. The public's level of mental health literacy related to recognition of specific mental disorders, and knowledge and beliefs about treatments is still relatively low. The government should consider public education campaigns to improve this.

Prevalence of metabolic syndrome and its risk factors among 10,348 police officers in a large city of China: A cross-sectional study.

The aim of this study was to assess the prevalence of metabolic syndrome (MS) and its risk factors among the police officers in a large city of China.A cross-sectional study was conducted in 10,348 police officers in 2017 in Changsha, a provincial capital located in central-south China. All participants underwent a physical examination to measure the compotents of MS and completed a questionnaire to collect data on potential risk factors. According to the current guidelines of China, MS was defined as the presence of any 3 of the following five traits: abdominal obesity, defined as a waist circumference ≥90 cm in men and ≥85 cm in women; fasting serum triglycerides ≥1.70 mmol/L, or drug treatment for elevated triglycerides; fasting serum high-density lipoprotein cholesterol <1.03 mmol/L, or drug treatment for low high-density lipoprotein cholesterol; blood pressure ≥130/85 mmHg, or drug treatment for elevated blood pressure; fasting plasma glucose ≥6.1 mmol/L, or 2-hour plasma glucose ≥7.8 mmol/L after a 75-g oral glucose load, or drug treatment for elevated blood glucose.The prevalence of MS was 23.2% (95% confidence interval [CI]: 22.2%–24.2%). The main risk factors associated with MS were older age (odds ratio [OR] 1.546, 95% CI 1.431–1.670), being male (OR 11.256, 95%CI 7.147–17.726), alcohol consumption (OR 1.250, 95% CI 1.070–1.461), and tobacco use (OR 1.398, 95% CI 1.232–1.586). Exercise was associated with decreased risk of MS (OR 0.865, 95% CI 0.755–0.991).The prevalence of MS was low in the study population. Its risk factors were similar to those identified in the general population of China. Lifestyle intervention is warranted in policemen to reduce the risk of MS and prevent diabetes and cardiovascular disease.

Prevalence and risk factors of small airway dysfunction and its association with smoking in China: a national cross-sectional study of 50 479 adults

BackgroundSmall airways dysfunction (SAD) is common but neglected respiratory abnormality. However, little is known about its prevalence, risk factors, and prognosis in the general population of China. MethodsThe nationally representative China Pulmonary Health study included more than 50 000 adults during 2012–15 using multistage stratified cluster sampling method, with valid spirometry measurements. Ten Chinese provinces, autonomous regions, and municipalities in mainland China were selected from six geographical regions, and all assessments were done in community health centres. SAD was defined as two of the three measures (ie, maximal mid-expiratory flow, forced expiratory flow 50%, and forced expiratory flow 75%) having below 65% of the predicted pre-bronchodilator values. Early-stage SAD was defined as SAD with normal forced expiratory volume in 1 sec (FEV1), forced vital capacity (FVC), peak expiratory flow, and FEV1/FVC, whereas pre-SAD was defined as early-stage SAD before bronchodilator inhalation, and pre-SAD plus post-SAD as early-stage SAD before and after bronchodilator inhalation. Logistic regression yielded adjusted odds ratios (aORs) for SAD associated with lifestyle and environmental factors. We estimated the total number of SAD in China using data from the present study and national census. FindingsOverall the prevalence of SAD, pre-SAD, and pre-SAD plus post-SAD was 43·5%, 21·4%, and 10·8%, respectively. The risk of SAD, especially pre-SAD plus post-SAD, was significantly associated with several factors, including cigarette smoking (aOR 1·16, 95% CI 1·04–1·28), exposure to particulate matter 2·5 (1·27 [1·12–1·44] at 50–74 μg/m3, and 1·48 [1·30–1·69] at ≥75 μg/m3), adiposity (1·37 [1·26–1·48] per 5 kg/m2 higher body-mass index) and parental history of respiratory diseases (1·11, 1·02–1·21). In 2015, an estimated 426 million (95% CI 411–467), 211 million (191–242), and 104 million (94–126) adults had SAD, pre-SAD, and pre-SAD plus post-SAD, respectively, in China. InterpretationIn China, spirometry-defined SAD is highly prevalent, with cigarette smoking, air pollution, and adiposity being major modifiable risk factors. Our findings highlight the need for early screening of SAD to reduce the health burden associated with chronic lung diseases in general populations.

Prevalence of Hepatitis B Virus Infection in Shenzhen, China, 2015\u20132018

China has nearly 10% of the general HBV carrier population in the world; this infection is the most common cause of chronic liver disease. Understanding HBV epidemiology is essential for future infection control, evaluation, and treatment. This study determined the prevalence of HBV infection in Shenzhen by serological testing and analysis in 282,166 HBV screening cases for the following: HBcAb, indicative of previous HBV infection; HBsAg, indicative of chronic (current) infection; HBsAb, indicative of immunity from vaccination; and 34,368 HBV etiological screening cases for HBV-DNA, indicative of virus carriage, in which 1,204 cases were genotyped and mutation analyzed for drug-resistance evaluation. Shenzhen was a highly endemic area of HBV throughout the study period (prevalence 9.69%). HBV infections were almost entirely in the 20 and older age groups with a male-to-female ratio of 1.16:1 which is approximately the same as the male-to-female ratio of the general population in China. However, only 71.25% of the general population retained HBV immune protection. Genotype B and C were identified as the most common agents; recombinant B/C and B/D also existed; some cases, however, could not be genotyped. NAs resistant mutation occurrence patterns were multitudinous; single mutation patterns of rtM204I/V and rtL180M occurrences accounted for majority, followed by the combinational mutation pattern L180M + M204I/V. Drug-resistance was prevalent, mainly occurring in the cross resistance patterns LAM + LdT and LAM + LdT + ETV, and significantly more critical in males. These results demonstrate that all people free from HBV infection should obtain injections of the vaccine or booster shots, and conventional virologic detection in a clinical laboratory center should incorporate genotype and mutation alongside the serological factors for etiology and develop better classification methods, such as sequencing.

Hepatitis B infection in the general population of China: a systematic review and meta-analysis

BackgroundHepatitis B virus (HBV) infection is a major public health problem in China. Over a decade has passed since the last National Hepatitis Seroepidemiological Survey was conducted in 2006. The lack of updated data on hepatitis B in China makes assessing the current prevalence and burden of the disease inadequate. In response to the above situation, a systematic review and meta-analysis was conducted to provide a better understanding of hepatitis B epidemiology in the general population of China.MethodsA systematic search was conducted in international databases (Medline through PubMed, EMBASE, Cochrane, Web of Science) and national databases (CBM, CNKI, WanFang Data) to retrieve primary studies published between January 1, 2013 and December 31, 2017. The pooled prevalence of HBV infection and 95% confidence intervals were calculated. Quality assessment, heterogeneity testing and publication bias assessment were also performed.ResultsOf the 27 studies included in the meta-analysis, the pooled estimated prevalence of HBV infection in the general population of China from 2013 to 2017 was 6.89% (95% CI:5.84–7.95%), which could be extrapolated to an estimated population of 84 million living with HBsAg in 2018. The prevalence of HBV infection in males was higher than that in females (5.88% vs 5.05%), and rural areas had a higher prevalence than urban areas (5.86% vs 3.29%). The highest prevalence of HBV infection was reported in Western provinces (8.92, 95% CI: 7.19–10.64%). In adults older than 20 years, the prevalence of HBV infection was approximately 7%, which was higher than that in children.ConclusionThe prevalence of HBV infection in the general population of China was classified as higher intermediate prevalence (5–7.99%), of which more than 90% of the HBV infection population included adults older than 20 years. The blocking of mother-to-infant hepatitis B transmission and plans involving timely birth dose of hepatitis B vaccine within 24 h should be implemented. Additionally, improving the quality of life and survival rate of the infected population through antiviral therapy and high-risk adult vaccination will be the priority of our future work. Moreover, various control measures should be implemented in different provinces across China.

Epidemic Situation of Tuberculosis in Prisons in the Central Region of China.

We aimed to investigate the epidemic situation of tuberculosis (TB) in prisons in the central region of China. Tuberculosis screening was carried out in two prisons in middle China. A sum of 3,459 prisoners accepted chest X-ray examination; 40 of them were diagnosed as active TB patients. The active TB prevalence (1,156/105) was significantly higher than that of the province and China's general population (P < 0.01). As for gender, TB prevalence in men's prison (1,589/105) was higher than that in the women's prison (946/105). Nevertheless, the risk of having TB in women's prison was much higher than that in the men's prison when compared with the TB prevalence from the province (women: OR = 2.37, 95% CI: 1.34, 4.22; men: OR = 1.53, 95% CI: 0.90, 2.60) and the China's general population (women: OR = 3.30, 95% CI: 2.15, 5.09; men: OR = 2.06, 95% CI: 1.29, 3.30). In view of the severe epidemic situation of TB in prisons, integrating medical resources to establish a consummate and effective management system is necessary.

Survey on the self-rated health of doctors and nurses at China′s 144 tertiary public hospitals

Objective To establish comprehensive understanding of the self-rated health of the Chinese doctors and nurses and probe into their influencing factors. Methods Data were drawn from a hospital performance survey, which was conducted by the Peking Union School of Public Health from March 18th to April 9th, 2019, among the 144 tertiary public hospitals in 31 provinces, autonomous regions, and municipalities. The survey included a cell-phone based questionnaire filled out by the sampled doctors and nurses, in which they were asked to rate their health using a 5-level Likert scale(from very poor to very good ). Mann-Whitney U test was used to analyze the differences in self-rated health between doctors and nurses. Chi-square test and two-class multivariate logistic regression were performed to analyze factors affecting self-rated health of the providers. Results Among the 144 sample hospitals, the proportion of doctors, who rated their health as healthy , was 20.30%(4 979/24 529), that of nurses was 28.92%(8 361/28 910). It was worse than that in some developed countries and lower than the general population in China. Multi-variate analysis showed that adequate sleeping time, satisfaction with the work and with the doctor-patient relationship, were positively associated with the level of self-rated health of the sampled doctors and nurses(P<0.05). It was also found that the longer the average weekly working time, the higher the recognition of the work load is too heavy , the lower the proportion of doctors and nurses who rated their health as healthy (P<0.05). Conclusions Sleep time, job satisfaction, workload and doctor-patient relationship are important factors affecting self-rated health of the Chinese doctors and nurses.

The relationship between Helicobacter pylori infection and depressive symptoms in the general population in China: The TCLSIH cohort study.

Depressive symptoms are a common, debilitating, and costly public health issue. Helicobacter pylori (H pylori) infection cause changes in the normal physiological state of the gastrointestinal (GI) flora. Although the physiological state of the GI tract is closely related to mental disorders, few population studies have examined the relationship between H pylori infection and depressive symptoms in the general population. The aim of this study was to examine whether H pylori infection is related to depressive symptoms among the general adult population. This cross-sectional study included 5558 inhabitants of Tianjin, China. H pylori infection was diagnosed with the carbon 13 breath test. Depressive symptoms were assessed using the Chinese version of 20-item Self-rating Depression Scale (SDS) with three cutoffs (45, 48, and 50) to indicate elevated depressive symptoms. Multiple logistic regression analysis were conducted to assess the association between H pylori infection and depressive symptoms. The prevalence of depressive symptoms (SDS≥45) was 12.7% in men and 17.4% in women. In multivariable models, the odds ratios and 95% confidence interval of having depressive symptoms by H pylori infection were 1.25 (1.01-1.56), 1.46 (1.11-1.91), and 1.46 (1.05-2.06) for three cutoffs: 45, 48, and 50 in women. However, no significant difference was found between H pylori infection and depressive symptoms in men. This study firstly suggested that H pylori infection was related to depressive symptoms in women in the general adult population. Further prospective studies or randomized trials are required to clarify the causality.

Associations of prenatal exposures to low levels of Polybrominated Diphenyl Ether (PBDE) with thyroid hormones in cord plasma and neurobehavioral development in children at 2 and 4 years

BackgroundNeurotoxic effects of Polybrominated Diphenyl Ethers (PBDEs) at low levels have not been well studied in human population, and whether the associations can be explained by thyroid hormones (THs) remains unclear. ObjectivesWe examined the associations of prenatal PBDE exposures with THs in cord plasma and neurobehavior of children at 2 and 4 years among general population in China. MethodsParticipants were mother-child pairs in the Shanghai-Minhang Birth Cohort Study. Nine PBDE congeners and THs (thyroid stimulating hormone, total thyroxine, free thyroxine, total triiodothyronine, and free triiodothyronine) were determined in cord plasma. Child Behavior Checklist (CBCL/1.5-5) were completed by caregivers to assess children's neurobehavioral development at 2 and 4 years. In the final analyses, 199 and 307 mother-child pairs at 2 and 4 years were included to examine associations of PBDEs with CBCL scores using Pearson-scale-adjusted Poisson regressions, and 339 subjects were included in linear regression models to investigate the associations between PBDEs and THs. ResultsBDE-47 had the highest detection rate of 83.82% with the median concentration of 0.19 ng/g lipid, followed by BDE-28, −99, −100 and −153 with detection rates nearly 50%. We found positive associations between prenatal PBDE concentrations and children's neurobehavior, including Somatic Complaints, Withdrawn, Sleep Problems and Internalizing Problems in girls, and Somatic Complaints and Attention Problems in boys. We also observed inverse associations of the sum of BDE-47, −28, −99, −100 and −153 with THs. However, by adding THs to the models examining associations between PBDEs and CBCL, the main results didn't measurably change. ConclusionsThis study adds new knowledge that prenatal PBDEs at low levels may be related to long-lasting behavioral abnormalities in children and reduced THs in cord plasma. However, the hypothesis that the neurotoxic impact of PBDEs may be explained by alterations in cord THs was not supported.

Short-term impact of breast cancer screening intervention on health-related quality of life in China: A multicentre cross-sectional survey.

The impact of participating in breast cancer screening programmes on health-related quality of life (HRQoL)is poorly understood. Based on a national breast cancer screening programme in China, a multicentre cross-sectional survey was conducted covering 12 provinces from September 2013 to December 2014. HRQoL of participants in the screening population and general population was evaluated by the three-levelEuroQol-five-Dimensions (EQ-5D-3L) instrument, and utility scores were generated through the Chinese value set. Univariate and multivariate regression analyses were performed to explore determinants of utility scores and anxiety/depression problems. For screening group and general population (n = 4756, mean age = 51.6 year old), the corresponding utility scores were 0.937 (95% CI, 0.933-0.941) and 0.953 (0.949-0.957) (P < .001). Pain/discomfort and anxiety/depression were the most common reported in both groups (51.4% and 34.3%, P < .001). Utility scores at prescreening, in-screening, and postscreening interview timings were 0.928 (0.921-0.935), 0.958 (0.948-0.969), and 0.938 (0.933-0.943), respectively (P < .001); the corresponding proportions of anxiety/depression reporting were 25.9%, 16.3%, and 21.1%, respectively (P=.004). Interview timing, geographical region, and insurance status were associated with HRQoL and anxiety/depression in women at high-risk of breast cancer. Utility scores of screening participants were significantly lower than that of general population in China, but the difference may be clinically insignificant. Further cohort studies using HRQoL measurements are needed.

Independent Influence of Blood Pressure on QTc Interval: Results from a General Chinese Population.

Aims We performed the current study primarily to characterize the independent association of blood pressure with heart rate-corrected QT (QTc) interval after adjusting for cardiovascular confounding factors and left ventricular mass (LVM) in a large general population in China. Methods All enrolled 10,553 permanent residents with age ≥ 35 years from Liaoning Province were investigated by a questionnaire and then subjected to physical examinations, laboratory analyses, and electrocardiogram (ECG) as well as echocardiogram at the same visit. Multivariate linear and logistic regression analyses were conducted to assess the independent association of blood pressure with QTc interval. Results Hypertensive subjects had significantly longer QTc interval and higher prevalence of prolonged QTc interval compared with normotensive ones in all subgroups stratified by gender and left ventricular hypertrophy (LVH) (all Ps ≤ 0.001). Multiple relevant clinical confounding factors and LVM were all adjusted in the multivariate linear and logistic regression analyses. As a result, both systolic blood pressure (SBP) and diastolic blood pressure (DBP) were independently associated with QTc interval (β = 0.12 and 0.16, respectively; Ps < 0.001). Furthermore, as categorical variables, hypertension was independently associated with prolonged QTc interval (OR = 1.71; P < 0.001). Sex-specific analyses revealed that the independent associations were detected in both males and females (all Ps < 0.001). Conclusions These key findings of the current study highlighted the fact that hypertension was significantly associated with prolonged QTc interval and the correlations were independent of confounding factors and LVM.

The prevalence and related factors of familial hypercholesterolemia in rural population of China using Chinese modified Dutch Lipid Clinic Network definition

BackgroundFamilial hypercholesterolemia (FH) is a common monogenic disease, while studies about the epidemiology for the general population in China was scarce. Aim of the study was to estimate the prevalence of FH and explore related factors by the Chinese modified Dutch Lipid Clinic Network (DLCN) definition.MethodsA total of 39,205 participants (15,463 males and 23,742 females) aged 18–79 years old were enrolled from the Henan Rural Cohort Study. FH was defined by the Chinese modified DLCN definition, and score > 5 was classified as FH. Logistic regression analysis was used to calculate the odds ratio and 95% confidence interval.ResultsCrude prevalence of probable/definite FH was 0.35% (0.29–0.41%), estimated by the Chinese modified DLCN definition. Prevalence in female was 0.38%, and in male, it was 0.32%. Age-standardized prevalence in female increased significantly around the age of 50 years. Moreover, there were no FH patients getting low-density lipoprotein cholesterol controlled to the recommended level. Multivariate logistic regression identified that older, overweight/obesity were positively associated with FH.ConclusionsThe current study indicated that FH was not rare in rural area of China (1 in 286). Effective early detection and timely control of FH must be strengthened to reduce disease burden.

Sleep quality in cigarette smokers and nonsmokers: findings from the general population in central China

BackgroundSleep problems are common in the general population. Cigarette smoking is common in the general population of China. Examinations of the prevalence of poor sleep quality among Chinese smokers and nonsmokers are still lacking. This study was designed to examine sleep quality and sleep disturbances among cigarette smokers and nonsmokers in the general population in central China.MethodsIn this population-based sampling project, we used a multi-stage sampling method to recruit survey participants from September 2012 to October 2012 in rural and urban areas of Hunan province, China. A total of 27,300 subjects were sampled from the general population and 26,282 completed the self-report of cigarette smoking characteristics. Cigarette smoker was defined as having smoked ≥100 cigarette in a lifetime and smoked during the last 28 days. Cigarette smoking characteristics were obtained from smokers, including cigarettes per day, years of smoking, quit attempts, and smoking cravings. The Pittsburgh Sleep Quality Index (PSQI) was applied to assess quality of sleep and sleep disturbances (PSQI score > 5).ResultsSignificantly more smokers than nonsmokers demonstrated poor sleep quality and sleep disturbances. Among smokers, linear regression analyses showed that poor sleep was inversely associated with cigarettes per day, and positively associated with years of smoking, quit attempts, and smoking craving. Logistic regression analysis showed that quit attempts and smoking cravings were associated with higher odds of sleep disturbances.ConclusionsSleep disturbances were more prevalent among cigarette smokers than nonsmokers. Smokers also varied in sleep problems on the basis of the characteristics of their smoking. Smokers should be informed about the link between cigarette smoking and poor sleep quality, and should be advised that one of several important health benefits from smoking cessation could be the improvement of sleep quality. Sleep therapy should be recommended as an adjunctive treatment for smoking cessation.

Occult HBV infection in patients with autoimmune hepatitis: A virological and clinical study.

Occult HBV infection (OBI) could have serious clinical consequences in patients receiving immunosuppressive therapy. We aimed to investigate the prevalence of OBI in Chinese patients with autoimmune hepatitis (AIH) and to analyze its clinical and virological features. 103 AIH cases were enrolled. Hepatitis B virus (HBV) serological markers were screened by chemiluminescence. HBV-DNA were detected by nest-PCR and real-time PCR. HBV genotyping and mutation analysis were performed by Sanger sequencing. Twenty-four out of 103 (23.30%) AIH patients had OBI as evidenced by positive HBV-DNA and negative hepatitis B surface antigen (HBsAg). HBV genotype C is the predominant genotype (57.89%), which had more amino acid (AA) substitutions in S region than that of B-genotype group (P=0.001). The distribution of AA substitution in the 'α' determinant region between genotype C and B were significantly different (P=0.042). In addition to those already reported OBI-associated AA substitutions (e.g., sG145R and sV184A), some new OBI-associated AA substitutions (e.g., sV106A, sC137* and sL176P) were found in AIH patients in our study. Three out of 24 (12.50%) OBI patients were diagnosed as decompensated cirrhosis, one patient with S deletion mutation and two patients with HBV extensive AA substitutions. There was a higher proportion of AIH patients with OBI than the general population in China, which can be either seropositive or seronegative-OBI in AIH patients is associated with some specific AA substitutions. The presence of deletion mutations and the extent of AA substitutions in the HBV S region may have predictive clinical implications.

Total Cerebral Small Vessel Disease Burden Is Related to Worse Performance on the Mini-Mental State Examination and Incident Dementia: A Prospective 5-Year Follow-Up.

Individual cerebral small vessel disease (CSVD) may cause cognitive decline. However, the association between total burden of CSVD and cognitive deterioration in the general population remains unclear. We aimed to determine whether total CSVD score is associated with cognitive performance change and incident dementia in the general population. In the longitudinal population-based Taizhou Imaging Study, 556 participants free of neurological disorders underwent brain MRI and neuropsychological testing at baseline. A total of 456 participants were followed up for cognitive performance for a mean (standard deviation) of 4.6 (0.6) years. Total CSVD score (range 0-4) was calculated by assigning 1 point for the presence of each of the following markers: lacune, white matter hyperintensity, cerebral microbleed, and perivascular space. Beta regression was used to evaluate the association between total CSVD burden and MMSE score change. The association of prevalent CSVD with incident dementia was studied using Fisher's exact test. CSVDs were present in 262 individuals (47.1%). The total CSVD score was significantly associated with MMSE score decline (p = 0.001). Compared to those with no CSVD, participants with 4 CSVD markers had a steeper decline in MMSE score (β: -0.53, 95% CI: -0.86 to -0.21; p = 0.001). A total of 15 participants developed dementia during follow-up. The presence of more than three CSVD markers at baseline was associated with a significantly higher risk of dementia (p = 0.020). Total CSVD burden appears to be associated with MMSE score decline and incident dementia in a general population in China.

Seroprevalence and associated factors of HSV-2 infection among general population in Shandong Province, China

BackgroundHerpes simplex virus type-2 (HSV-2) infection is the main cause of genital ulcer disease and increases the risk of HIV acquisition. Little information is available regards the epidemiological characteristics of HSV-2 among general population in China. The aim of this study was to explore seroprevalence and associated factors of HSV-2 and provide information for design of HSV-2 control strategy in Shandong, China.MethodsIn this cross-sectional study, a total of 8074 persons, 18–49 years of age, were selected using multi-stage probability sampling to represent the general population of Shandong in 2016. Demographic data were collected through face-to-face interviews. Other variables were obtained by self-administered questionnaire surveys. Blood was collected for HSV-2 IgG detection with ELISA.ResultsA total of 7256 sexually-active participants were included in the analysis. The weighted seroprevalence of HSV-2 infection was 4.2% (95% confidence interval [CI], 3.2–5.3) in females, which was significant higher than that in males (2.7%; 95% CI, 1.1–4.2) (P = 0.04). The seroprevalence of HSV-2 was higher in individuals from eastern region (6.4%; 95% CI, 5.9–6.9) and urban areas (4.3%; 95% CI, 2.6–6.0) of Shandong than those from other regions (P < 0.01). Associated factors for HSV-2 infection among men were being urban residents (adjusted odds ratio [AOR], 2.36; 95% CI, 1.14–4.88), having two or more sex partners in the past year (AOR, 3.22; 95% CI, 1.90–5.43) and having commercial sex (AOR, 1.51; 95% CI, 1.00–2.26). Among females, being divorced or widowed (AOR, 1.79; 95% CI, 1.08–2.97), having a tattoo (AOR, 2.89; 95% CI, 1.07–7.84), and being dissatisfied with the sex activity quality (AOR, 2.12; 95% CI, 1.24–3.63) was associated with HSV-2 infection.ConclusionsThis study showed a relatively low burden of HSV-2 in Shandong province, China compared with the seroprevalence reported in many other provinces and countries. HSV-2 control programs in Shandong should focus on eastern, urban and female residents, and pay more attention to individuals with identified associated factors.

Elevated triglycerides rather than other lipid parameters are associated with increased urinary albumin to creatinine ratio in the general population of China: a report from the REACTION study

BackgroundDyslipidaemia has always been regarded as the cornerstone of arteriosclerosis and is related to the pathogenesis of renal insufficiency. However, it is unclear which routinely available lipid parameter is related to urinary albumin to creatinine ratio (UACR). The purpose of this study was to examine the lipid abnormalities associated with UACR in the general population in China.MethodsThe present study was nested in an ongoing Risk Evaluation of cAncers in Chinese diabetic Individuals: A lONgitudinal (REACTION) study, which was designed to demonstrate the association of abnormal glucose metabolism with the risk of cancer in the Chinese population. This cross-sectional study included 34, 569 subjects (11, 390 males and 23, 179 females) from 8 different regional community cohorts, with an average age of 57.9 years. The UACR data were divided into the < 25% group, the 25–49% group, the 50–74% group, and the ≥ 75% group according to the quartile division of the centre where the subjects visited. The lipid classes were defined according to the guidelines for the prevention and treatment of dyslipidaemia in Chinese adults. Multiple logistic regression analysis was used to evaluate the association of the lipid parameters and UACR.ResultsMultivariable regression analysis revealed that compared with the other lipid parameters, triglycerides (TG) showed an adjusted odds ratio that was significant in model 1–4. This relationship was attenuated after adjusting for Haemoglobin A1c (HbA1c) and blood pressure (BP), but TG ≥ 2.3 mmol/L was still significantly associated with UACR in total subjects and in both men and women (OR: 1.131, 95% CI 1.065–1.203, P < 0.001 in total subjects; OR: 1.134, 95% CI 1.022–1.258, P = 0.017 in men; OR: 1.129, 95% CI 1.046–1.219, P = 0.002 in women). In the stratified analysis, elevated TG was significantly associated with increased urinary albumin in subjects with eGFR ≥ 90 mL/min per 1.73 m2, 5.6 ≤ FBG < 7.0 or 7.8 ≤ PBG < 11.1 mmol/L, 24 ≤ BMI < 28 kg/m2, 120 ≤ SBP < 140 and/or 80 ≤ DBP < 90 mmHg.ConclusionsWe conclude that high TG levels rather than total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, or non-high-density lipoprotein cholesterol levels are associated with UACR in the general population in China.

PCN286 COMPARING EQ-5D-3L AND EQ-5D-5L PSYCHOMETRIC PROPERTIES OF COMMON CANCERS IN CHINA: A CROSS-SECTIONAL STUDY

The EQ-5D-3L has been commonly used for years as a generic measurement of health utility. The recently developed Chinese version of EQ-5D-5L was found to be more sensitive in discriminating different health levels in general population in China, when compared with EQ-5D-3L. However, the psychometric properties of the EQ-5D-5L in cancer patients remains unknown in China. This study aimed to compare the performance between EQ-5D-3L and EQ-5D-5L among cancer patients. A hospital-based cross-sectional survey was conducted in 3 provincesin Sep15, 2016.Patientsof three common cancers (lung, breast and colorectal) were recruited to complete the EQ-5D-3L and EQ-5D-5L questionnaire.Discriminatory power (indicator: Shannon index (H’) and Shannon evenness index (J’)), ceiling effect (the proportion of choosing fully health state) and convergent validity were compared between the two instruments. A total of 1 802 cancer patients (lung cancer: 600, breast cancer: 601, colorectal cancer: 601) were included, with a mean age of 55.6 years. The overall utility scores were0.790 (95% CI: 0.778-0.801) of EQ-5D-3L and 0.803 (0.790-0.816) of EQ-5D-5L (P<0.0001).Compared with the EQ-5D-3L (H’=1.10, J’=0.70), an improved discriminatory power was observed in the EQ-5D-5L (H=1.47, J’=0.93), especially onthe dimension of anxiety/depression. The ceiling effect was diminished in the EQ-5D-5L (26.5%) than EQ-5D-3L (34.5%) (P<0.0001), mainly reflected in pain/discomfort and anxiety/depression dimensions. Theconvergent validityof EQ-5D-5L were also observed to be higher than those of EQ-5D-3L. A similar pattern was also observed in detailed cancer-specific analyses, taking breast cancer as an example: the utility wasevaluated as 0.841 (0.825-0.857) by the EQ-5D-5L and 0.821 (0.806-0.837) by the EQ-5D-3L. With greater discriminatory power, convergent validity and lower ceiling, the EQ-5D-5L might be alsoa good choice when EQ-5D-3L is unavailable , but it may result in fewer QALYs gained due to estimated higher utility.

Demographic characteristics of newly diagnosed HIV-seropositive patients: a single-center retrospective analysis

Background: To characterize the HIV-seropositive patients who underwent HIV screening and counseling in a Chinese general hospital and to provide evidence for the HIV/AIDS prevention and control strategy in China. Methods: We retrospective analyzed data of all the patients who were screened for HIV infection and found to be HIV-positive in our hospital from January 2010 to December 2016. The demographic and social characteristics of the HIV-seropositive patients were described in order to estimate the risk factors. Results: Among 611,445 patients who were screened for HIV, 329 cases were confirmed to be HIV-positive by Western blot test. These patients were predominantly male, accounting for 83.59% (275/329) of cases. Majority of male patients 82.91% (228/275) acquired HIV infection via sexually transmitted route and about 122 male patients (53.51%) were homosexual. The female gender accounted for only 16.41% (54/329) and 77.78% (42/54) of them were infected by a male partner. Conclusions: Our results showed the MSM (men who have sex with men), females and adults over 65 years old have different sexual and psychosocial characteristics and these characteristics should be taken into account for HIV prevention, intervention and treatment when preventative strategies of HIV/AIDS shift from high-risk groups to the general population in China.

Translation and validation of the Chinese version of the Cancer Stigma Scale.

To test the reliability and validity of the Chinese version of the Cancer Stigma Scale (CASS). After translation, back-translation and cross-cultural adaptation of the CASS into Chinese (C-CASS), a random online survey of the general population in China was conducted. Reliability was analyzed by internal consistency (Cronbach's α) and construct validity was analyzed by confirmatory factor analysis. The C-CASS was evaluated in a sample of 382 non-cancer patients through online format. The study found that the C-CASS had satisfactory internal reliability (Cronbach's α of the overall scale and six components was 0.88 and 0.70-0.89, respectively). Confirmatory factor analysis confirmed the six-factor structure (χ2/df = 2.2, GFI = 0.91, CFI = 0.94, RMSEA = 0.056, SRMR = 0.065). Younger individuals and those who had less knowledge of cancer showed more negative attitudes towards cancer. The C-CASS had adequate internal consistency, reliability and indices of model fit, allowing its feasible use to assess levels of cancer stigma in Chinese populations.
