RESUMO
Objective: The direction and intensity of population aging on the burden of non-communicable diseases (NCDs) in China from 1990 to 2019 were analyzed, and the burden of NCDs in 2050 was predicted. Methods: The disease-specific disability-adjusted life years (DALYs), years of life lost (YLLs), and years lived with disability (YLDs) in the Chinese population from 1990 to 2019 were obtained from the Global Burden of Disease Study.The differences in indicators from 1990 to 2019 were attributed to the contribution of age structure, population size, and all other causes. The Bayesian age-time-cohort models were used to predict DALYs from NCDs to 2050. Results: The absolute level of DALYs caused by NCDs increased by 7.460 million from 1990 to 2019, and the age structure contributed 186.0% (95% Uncertainty Intervals (UIs): 178.4%-193.6%), population size contributed 77.0% (95% UIs: 69.5%-80.8%), all other causes contributed -163.0% (95% UIs:-163.1%- -159.3%). DALYs caused by NCDs consist of 2.527 million YLLs and 4.934 million YLDs, in which the contribution of age structure to YLLs and YLDs was 414.6% (95% UIs: 396.2%-432.5%) and 69.1% (95% UIs: 66.7%-71.4%), respectively. From 2019 to 2050, the diseases with increased DALYs due to changes in age structure are cardiovascular diseases, neoplasms, chronic respiratory diseases, neurological disorders, sense organ diseases, diabetes and kidney diseases, musculoskeletal disorders, digestive diseases, mental disorders, and skin and subcutaneous diseases in descending order. Conclusions: From 1990 to 2019, except for skin and subcutaneous diseases, the burden of other NCDs attributable to population aging increased, mainly due to disability. By 2050, the burden of NCDsattributable to population aging will continue to rise.

HIV cluster detection and response (CDR) is a critical strategy to end the HIV epidemic by offering information to identify prevention and care services gaps. The risk metrics for HIV clusters can be classified into three groups: growth-based metrics, characteristic-based metrics, and phylogeny-based metrics. When identifying HIV risk clusters, the public health response can reach people in the affected networks, including people with undiagnosed HIV, people with diagnosed HIV who might not be accessing HIV care or other services, and people without HIV who would benefit from prevention services. To provide references for HIV precise prevention in China, we summarized the risk metrics and the intervention measures for CDR.

Objective: To determine the causal association between long-term Nitrogen dioxide (NO2) exposure and the risk of cardiovascular hospitalization. Methods: Based on a sub-cohort of a community-based prospective cohort study, a total of 36 271 participants were recruited from 35 communities randomly selected in Guangzhou in 2015. The annual average exposure of NO2, demographic characteristics, lifestyle factors, and information on the causes of hospitalization was collected. We applied marginal structural Cox models to investigate the effect of NO2 on cardiovascular hospitalization. Demographic and behavioral factors also stratified results. Results: The mean age of participants in the present study was (50.9±17.8) years, and the cardiovascular admission rate was 8.7%, with 203 822 person-years of follow-up. The annual mean NO2 concentration was 48.7 μg/m3 during 2015-2020. For each 10 μg/m3 increase in NO2 concentrations, the HRs (95%CIs) of total cardiovascular hospitalization, cardiovascular hospitalization, and cerebrovascular hospitalization were 1.33 (1.16-1.52), 1.36 (1.16-1.60) and 1.25 (1.00-1.55), respectively. Participants who were never married/married, with secondary education, high exercise frequency, or non-smokers/current smokers may be more susceptible than their counterparts. Conclusion: Long-term exposure to NO2 significantly increased hospitalization risk for cardiovascular disease.

OBJECTIVE@#To explore the discrepancy between behavioral-indicated candidacy and perceived candidacy (behavioral-perceived gap) and its associated factors of human immunodeficiency virus (HIV) pre-exposure prophylaxis (PrEP) among men who have sex with men (MSM), so as to identify the focus population of PrEP interventions and to design and implement targeted interventions.@*METHODS@#We recruited a sample of 622 HIV-negative MSM who were regular clients of a community-based organization located in Chengdu, China, from November to December 2021. A cross-sectional questionnaire was used to collect the participants' information on social demographics, PrEP-related knowledge and cognitions, and risk behaviors. In this study, behaviorally eligible for PrEP was defined as performing at least one type of high-risk behavior in the past six months, including inconsistent condom use, sex with an HIV-positive partner, confirmed sexual transmitted infections (STI) diagnosis, substance use, and post-exposure prophylaxis (PEP) experience. Logistic regression models were fitted, and multivariate analyses were adjusted for social demographics.@*RESULTS@#Among the 622 eligible participants, 52.6% (327/622) were classified as behaviorally eligible for PrEP. Only 37.9% (124/327) of the participants perceived themselves as appropriate candidates for PrEP and 62.1% (203/207) had discrepancy between behavioral-indicated and perceived candidacy. 85.9% (281/327) had heard of PrEP, and 14.2% (40/281) accessed PrEP information through health care providers. Of the 327 participants eligible for behavior-indicated PrEP use, about half (47.1%) knew how to obtain PrEP medication and 33.0% had a professional PrEP counseling experience. The majority (93.3%) had no or few friends using PrEP. 54.1% scored eight or above in PrEP knowledge level. 66.7% reported having two or more sexual partners in the past six months. After adjusting for age and recruitment channel, we found six factors that were associated with perceived candidacy for PrEP, including PEP use [adjusted odds ratio (ORA)=2.20; 95% confidence interval (CI): 1.33-3.63], PrEP availability (ORA=1.69; 95%CI: 1.06-2.68), a greater number of PrEP-using friends (ORA=4.92; 95%CI: 1.77-13.65), PrEP know-ledge (ORA=2.21; 95%CI: 1.38-3.56), multiple sexual partnership (ORA=1.77; 95%CI: 1.07-2.94), and perceiving a higher risk of HIV infection (ORA=4.02; 95%CI: 1.73-9.32). Substance use during sex and PrEP information channel were not statistically associated with this beha-vioral-perceived gap.@*CONCLUSION@#We observed a high discrepancy between behavioral-indicated and perceived candidacy for PrEP among Chengdu MSM in China. Future PrEP implementation efforts should be made in skills training in assessing HIV infection risk, increasing PrEP knowledge, providing professional PrEP counselling, and fostering PrEP support environment.

Objective: To investigate the association between physical exercise and non-alcoholic fatty liver disease (NAFLD) in people infected with HBV. Methods: The information about the 3 813 participants infected with HBV, including the prevalence of NAFLD, prevalence of physical exercise and other covariates, were collected from the National Science and Technology Major Project of China during 2016-2020. The logistic regression model was used to evaluate the association between physical exercise and NAFLD in HBV infected patients, and subgroup analysis was performed to identify the effect modifiers. Results: A total of 2 259 HBV infected participants were included in the final analysis and 454 (20.10%) had NAFLD. After adjusting for covariates, we found that moderate physical exercise was a protective factor for NAFLD (OR=0.66, 95%CI: 0.46-0.94). Subgroup analysis suggested that the protective effect of moderate physical exercise on NAFLD might be stronger in women (OR=0.61, 95%CI: 0.36-1.01), those <45 years old (OR=0.24, 95%CI: 0.06-0.80), those who had low education level (OR=0.16, 95%CI: 0.04-0.49), those who had low annual income (OR=0.39, 95%CI: 0.16-0.89 for <30 000 yuan RMB; OR=0.64, 95%CI: 0.40-1.00 for 30 000-80 000 yuan RMB), those who had hypertension (OR=0.45, 95%CI: 0.21-0.88), those with BMI ≥24.0 kg/m2 (OR=0.66, 95%CI: 0.43-1.01), those who had more daily fruit or vegetable intake (OR=0.61, 95%CI: 0.38-0.97), those who had more daily meat intake (OR=0.49, 95%CI: 0.23-0.97), and those who had no smoking history (OR=0.66, 95%CI: 0.45-0.95) or passive smoking exposure (OR=0.61, 95%CI: 0.37-0.97). Conclusions: Among HBV infected patients, moderate physical exercise was negatively associated with the prevalence of NAFLD. Women, young people, those who had low education level, those who had low annual income, those with hypertension, those with high BMI, those who had more daily fruit or vegetable and meat intakes, and those who had no smoking history or passive smoking exposure might be more sensitive to the protective effect.

Objective: To investigate the association between the response to repeated negative HIV testing and the risk sexual behaviors in men who have sex with men (MSM) in Chengdu. Methods: A total of 610 MSM were recruited by convenience sampling method through Chengdu Tongle Health Consultation Service Centre from March to May 2022. Data were collected from the MSM through questionnaire survey, including the demographic characteristics, sexual behaviors in the past 6 months, the response to rerpeated negative HIV testing. Univariate and multivariate logistic regression models were conducted to analyze the association between the response to repeated negative HIV testing and risk sexual behavior. Results: A total of 579 (94.9%) participants participated in the questionnaire survey and 354 (61.1%) subjects were included in the study.For the negative HIV testing, some MSM believed that they had taken effective protection measures (17.03±2.20), some believed that they were lucky (7.50±1.87) and some believed that they were at low risk (8.87±3.62). Multivariate logistic regression model showed that protected sexual behavior was negatively associated with group sex (aOR=0.80, 95%CI: 0.67-0.95), lucky was positively associated with casual sex (aOR=1.20, 95%CI: 1.06-1.35), inconsistent condom use (aOR=1.21, 95%CI: 1.06-1.37), group sex (aOR=1.26, 95%CI: 1.00-1.60), and multiple sexual partners (aOR=1.24, 95%CI: 1.09-1.42) and low risk perception was positively associated with multiple sexual partners only (aOR=1.08, 95%CI: 1.01-1.15). Conclusions: There were high levels of recognition of protected sexual behavior and lucky dimensions in response to repeated negative HIV testing and well risk perception in MSM in Chengdu. In HIV testing and counseling services, intervention and risk warning should be strengthened in MSM who believed that they are lucky to improve their awareness of safe sex and reduce the negative effects of fluke mind.

The rapid development of the globalization process has brought global health problems and made global health a hotspot in the world. China’s “One Belt and One Road” initiative has strengthened economic and trade exchanges between China and Asia, Africa, Europe, and has also increased health risks such as the spread of infectious diseases, disease spectrum, and lifestyle changes, posing challenges to the development of global health in China. Based on the history of global health, this paper made a brief review of the current status and future development of global health research. It pointed out that China’s global health research started late and had many shortcomings. In the context of the One Belt And One Road initiative, We should seize opportunities and meet challenges to contribute to the construction of "Healthy China" and the promotion to global health.
RESUMO
Objective To describe the current situation of diarrhea in children under five years old in Nepal and to explore its influencing factors. Methods Data were collected from the open-access database, Nepal Demographic and Health Surveys in 2006, 2011 and 2016. Chi-square ( 2) and Wilcoxon rank sum test were used to compare difference of potential risk factors between groups with and without diarrhea. Multiple Logistic regression model was adopted to identify significant influencing factors on diarrhea in children under five years old in Nepal. Results In 2006, 2011 and 2016, the incidence of diarrhea children under five in Nepal was 12.3%, 13.3% and 6.8%, respectively. Univariate analysis of the potential influencing factors showed that there were significant differences in the gender, water source, toilet facilities and fuel type, age of children, age of mother when she gave birth to the child and education years of mother and children with and without diarrhea (all P<0.05). Multiple analysis revealed that improved toilet facilities (OR=0.874, 95% CI: 0.769-0.994, P=0.041) and the age of children(OR=0.613, 95% CI: 0.580-0.645, P<0.001) were protective factors of childhood diarrhea, and the risk of boys was higher than that of girls(OR=1.277, 95% CI: 1.147-1.423, P<0.001). Conclusions From 2006 to 2016, the incidence of diarrhea in children under five years old in Nepal was decreasing. Toilet facilities, age of children and gender of children were identified as the influencing factors of childhood diarrhea.

<p><b>OBJECTIVE</b>To understand the infection status and epidemiological features of HBV in permanent residents of Shenzhen city.</p><p><b>METHODS</b>A multi-stage stratified random sampling method was performed for questionnaire survey to permanently-registered residents of 1-59 years old in Luohu and Baoan district of Shenzhen in 2010, and blood samples of the subjects were collected. Hepatitis B virus-related surface antigen (HBsAg) and hepatitis B virus surface antibody (anti-HBs) were detected with ELISA.</p><p><b>RESULTS</b>The total 3771 studied population showed 252 HBsAg positive and 2712 anti-HBs positive residents with the standardization prevalence as 9.73% and 72.83% , respectively. The difference of the prevalence of HBsAg and anti-HBs between males and females were not statistically significant (P > 0.05). The prevalence of HBsAg was reduced with increasing age. The differences of the prevalence of HBsAg between Shenzhen permanent registered and non-permanent registered population were not significant, but the prevalence of anti-HBs in Permanent registered residents (78.32%) was higher than in non-permanent (66.03%, χ(2) = 41.613, P < 0.001). The prevalence of HBsAg was significantly different in various occupational and educational levels. Peasants had the highest prevalence (24.13%) and medical workers had the highest prevalence of anti-HBs (89.10% ). People with junior high school education had the highest prevalence of HBsAg (12.76%) and the lowest of anti-HBs (62.45%). Population with high-level education had the highest prevalence of anti-HBs(81.00% average). The prevalence of HBsAg was over 10% in people who were born in Shenzhen and Guangdong province, and the anti-HBs was the highest in Shenzhen population with the prevalence as 74.48% and 76.47% , respectively.</p><p><b>CONCLUSION</b>In the Shenzhen resident population, the overall prevalence of HBV was lower than the average level of Guangdong province, but higher than the national wide.</p>

<p><b>BACKGROUND</b>Trabeculectomy has become a mainstream treatment in intraocular pressure (IOP) reduction for primary angle-closure glaucoma (PACG); combined trabeculectomy and cataract surgery was reported to reduce IOP and simultaneously improve vision for patients with PACG and coexisting cataract. This study was specialized to compare the efficacy and safety of combined phacotrabeculectomy with that of trabeculectomy only in the treatment of PACG with coexisting cataract.</p><p><b>METHODS</b>This is a comparative case series study. Thirty-one patients (31 eyes) with PACG and coexisting cataract were enrolled. Of these, 17 underwent phacotrabeculectomy and 14 underwent trabeculectomy alone. IOP, filtering blebs, and complications were compared at the final follow-up. Complete success was defined as a final IOP less than 21 mmHg without IOP-lowering medication.</p><p><b>RESULTS</b>After 10 months of postoperative follow-up, the phacotrabeculectomy and trabeculectomy groups showed no significant differences regarding IOP reduction ((20.59 ± 7.94) vs. (24.85 ± 14.39) mmHg, P = 0.614), complete success rate (88% vs. 71%, P = 0.370), formation rate of functioning blebs (65% (11/17) vs. 93% (13/14), P = 0.094), and complications (41% (7/17) vs. 57% (8/14), P = 0.380). IOP-lowering medication was not required for most of the patients in both groups. Additional surgery interventions, including anterior chamber reformation and phacoemulsification, were needed in the trabeculectomy group, whereas no surgery was needed postoperatively in the phacotrabeculectomy group.</p><p><b>CONCLUSION</b>Phacotrabeculectomy and trabeculectomy treatments exhibit similar IOP reduction, successful rates, and complications when it comes to treating PACG patients with coexisting cataract, although additional surgery intervention may be needed for a few cases with cataract and complications after trabeculectomy.</p>

<p><b>OBJECTIVE</b>To identify patterns of hand, foot and mouth disease (HFMD) incidence in China during declining incidence periods of 2008, 2009, and 2010.</p><p><b>METHODS</b>Reported HFMD cases over a period of 25 months were extracted from the National Disease Reporting System (NDRS) and analyzed. An interrupted time series (ITS) technique was used to detect changes in HFMD incidence rates in terms of level and slope between declining incidence periods of the three years.</p><p><b>RESULTS</b>Over 3.58 million HFMD cases younger than 5 years were reported to the NDRS between May 1, 2008, and May 31, 2011. Males comprised 63.4% of the cases. ITS analyses demonstrated a significant increase in incidence rate level (P<0.0001) when comparing the current period with the previous period. There were significant changes in declining slopes when comparing 2010 to 2009, and 2010 to 2008 (all P<0.005), but not 2009 to 2008.</p><p><b>CONCLUSION</b>Incremental changes in incidence rate level during the declining incidence periods of 2009 and 2010 can potentially be attributed to a few factors. The more steeply declining slope in 2010 compared with previous years could be ascribed to the implementation of more effective interventions and preventive strategies in 2010. Further investigation is required to examine this possibility.</p>

Objective The purpose of this study was to explore the spatial clustering,specific clustering areas,as well as changing trend of clustering areas of hand-foot-mouth disease (HFMD).Methods Exploratory spatial data analysis (ESDA) was used to conduct spatial statistical analyses for the HFMD using 2008-2011 data at both provincial and county/district levels.Results The Global Moran' s I coefficients appeared to be 0.3336,0.6074,0.3372,0.4620 and 0.4367 for 2008-2011and for the combined 4 years,respectively.The corresponding P-values were 0.002,0.001,0.004,0.001 and 0.001 respectively,when using the Monte Carlo tests with all the P-values less than 0.05.Moran' s Ⅰ coefficients ranged between 0.3 and 0.7,showing the appearance of moderate or higher clustering nature.Based on the results from nationwide analyses on clustering areas at the county/district levels between 2008 and 2011 (Moran' s I=0.5198,P=0.001),it appeared a moderate clustering nature.When local autocorrelation analysis was applied at the provincial level,3 hot spot areas in Beijing,Tianjin and Shanghai cities in 2008;7 hot spot areas in Beijing,Tianjin,Hebei,Shanxi,Shanghai,Jiangsu and Shandong in 2009; four hot spot areas:Beijing,Tianjin,Guangdong and Guangxi; five hot spot areas:Fujian,Jiangxi,Hunan,Guangdong and Guangxi in 2011,were discovered.390 hot-spot counties/districts were found through local autocorrelation analyses using the three-year data of 2008 to 2010.Conclusion Spatial clustering nature of HFMD incidence between 2008 and 2011 in China appeared to be moderate or high,with the clustered areas a north to south shifting trend.However,further investigation was in need to address this changing trend.
RESUMO
<p><b>BACKGROUND</b>Early intensive insulin therapies in newly diagnosed type 2 diabetic patients may improve beta-cell function and yield prolonged glycemic remissions. This study was performed to evaluate the relationship between the glycemic remission and beta-cell function and assess the variables predictive of long-term near-normoglycemic remission.</p><p><b>METHODS</b>Eighty-four newly diagnosed type 2 diabetic patients were treated with 2-week continuous subcutaneous insulin infusion (CSII) and followed up longitudinally. Intravenous glucose tolerance tests (IVGTTs) were performed, and blood glucose, hemoglobin A1c (HbA1c) and insulin were measured at baseline, after CSII and at 2-year visit. The patients who maintained glycemic control for two years were defined as the remission group and those who relapsed before the 2-year visit were the non-remission group.</p><p><b>RESULTS</b>The duration to be diagnosed of the patients (from the time that patients began to have diabetic symptoms until diagnosis) in the remission group was shorter than that in the non-remission group (1.00 month vs 4.38 months, P = 0.040). The increase of the acute insulin response (AIR) was maintained after 2 years in the remission group compared with AIR measured immediately after intervention (413.05 pmol*L(-1)*min(-1) vs 408.99 pmol*L(-1)*min(-1), P = 0.820). While AIR in the non-remission group significantly declined (74.71 pmol*L(-1)*min(-1) vs 335.64 pmol*L(-1)*min(-1), P = 0.030). Cox model showed that a shorter duration to be diagnosed positively affected the duration of near-nomoglycemic remission with an odds ratio (OR) 1.019, P = 0.038, while fasting plasma glucose (FPG) and post-breakfast plasma glucose (PPG) after CSII were the risk factors (OR 1.397, P = 0.024 and OR 1.187, P = 0.035, respectively).</p><p><b>CONCLUSION</b>The near-normoglycemic remission is closely associated with long-term maintenance of beta-cell function and occurs more commonly in patients with shorter duration to be diagnosed and better glycemic control during CSII.</p>

<p><b>OBJECTIVE</b>To evaluate the reliability and validity of parent proxy-report scales of Pediatric Quality of Life Inventory Version 4.0 (PedsQL 4.0) Generic Core Scales, the Chinese Version.</p><p><b>METHODS</b>3493 school students aged 6-18 years were recruited using multistage cluster sampling method. Health-related quality of life was assessed using the above-mentioned PedsQL 4.0 scales. The internal consistency was assessed, using Cronbach's a coefficient, while its validity was tested through correlation analysis, t-test and exploratory factor analysis.</p><p><b>RESULTS</b>The internal consistency reliability for Total Scale Score (Cronbach's alpha = 0.90), Physical Health Summary Score (alpha= 0.81), and Psychosocial Health Summary Score (alpha= 0.89) were excellent. Six major factors were extracted by factor analysis which basically matched the designed structure of the original version accounting for nearly 66% of the variance. The total Scale Score significantly decreased by 3.5 to 13.3 (P < 0.05) in children and adolescents who had diseases including cold, skin hypersensitiveness, food allergy, courbature or arthralgia, breathlessness with a frequency of 6 times or more per year or had asthma as compared to those with lower frequency (< or = 5 times/y) of the diseases or without asthma. We found moderate to high correlations between items and the subscales. Correlation coefficients ranged between 0.45 to 0.84 (P < 0.01).</p><p><b>CONCLUSION</b>The reliability and validity of the parent proxy-report scales of PedsQL 4.0 Generic Core Scales of the Chinese Version were as good as the original version. Our findings suggested that the scales could be applied to evaluate the health-related quality of life in childhood children in similar Chinese regions to Guangzhou.</p>

Objective To study the effect of dialysis adcquacy,microinflammation and residual renal function on nutritional status of hemodialysis patients.Methods One hundred and fourteen patients were enrolled in this study.Kt/V,?_2-MG and serum iPTH were measured as markers of hemodialysis adequacy.Nutritional evaluation included MQSGA,Alb,Hb,TF,IGF-1,IGFBP-3 and anthropometrics such as HGS,BSF,TSF,MAC,MAMC and AMA.Serum IL-6,TNF-?and CRP were detected to assess microinflammation.Urinary volume of 24 hours was measured to investigate the residual renal function (RRF).Results (1)There were different correlations and regressive associations of Kt/V,iPTH and?_2-MG with HGS,MAMC,AMA,Alb,Hb,nPCR,IGF-1 and MQSGA respectively.(2) There were significant correlations and regressive associations of RRF to HGS,TSF,MAMC,Alb,nPCR and IGF-1 within the first year of hemodialysis.(3) There were different correlations and regression relationships of IL-6,TNF-?and CRP with HGS、MAMC、AMA、Alb、TSF、Hb、nPCR、IGF-1 respectively.(4) Multivariate analysis showed that Kt/V,iPTH,IL-6, TNF-?,?_2-MG and RRF were influencing factors,among them,Kt/V,iPTH,IL-6 and TNF-?were independent predictors of nutritional status.Conclusions Hemodialysis adequacy and micruinflammation may impact on nutritional status.Residual renal function may be involved in nutritional status in the first year of hemodialysis.Kt/V,iPTH,IL-6 and TNF-?are independent factors affecting nutritional status.
