Background
The HIV epidemic is growing among men who have sex with men (MSM) in China. Frequent HIV testing is associated with reduced HIV risk among MSM. However, little is known about factors associated with frequency of HIV testing in this population. We aimed to characterise sociodemographic characteristics and psychosocial factors associated with frequent HIV testing in HIV-negative MSM in Guangzhou, China.Methods
We did this cross-sectional survey among MSM who were visiting a gay-friendly community clinic in Guangzhou between Sept 2 and Nov 24, 2016. Men were eligible if they were aged 18 years or more, self-identified biological males, and reported sexual contact with male partners in the past 12 months. Surveys were self-administered via a handheld electronic tablet. We collected sociodemographic characteristics and psychosocial measurements. HIV testing frequency was defined by three groups based on testing history: never tested, irregularly tested, or frequently tested. Irregularly tested MSM tested less than twice per year or tested less than every 6 months. Frequently tested MSM tested twice per year or tested more than once every 6 months. We compared sociodemographic and psychosocial measurements among MSM who never tested, irregularly tested, and frequently tested using χ2 testing or one-way ANOVA. Multinomial logistic regression and ordinal logistic regression were used to identify independent correlates that were associated with differences in frequency of HIV testing. Ethics approval was obtained from the ethics review boards of the Guangzhou Center for Disease Control and Prevention and the University of Pittsburgh.Findings
495 MSM participated in this survey. Three participants refused to answer HIV testing history information and were excluded from this present analysis. Among the 492 MSM, 67 (13·6%) were never tested, 207 (42·1%) were tested irregularly, and 218 (44·3%) were tested frequently in the past 2 years. MSM who tested for HIV frequently were more likely to be older (p=0·001), reside in Guangzhou (p=0·016), and have higher monthly income (p=0·016). Compared with MSM who tested frequently, MSM who never tested were less likely to report that their sexual partner had ever received HIV tests (adjusted odds ratio 0·27; 95% CI 0·11–0·63) or that their good friends had ever received HIV tests (0·42; 0·22–0·78). Compared with MSM who tested frequently, those who never tested were also less likely to report having HIV-positive gay friend (0·39; 0·19–0·78) or ever discussing HIV with sexual partners (0·24; 0·12–0·47); they were more likely to report perceiving barriers to HIV testing (1·13; 1·03–1·24). Compared with MSM who tested frequently, those who tested irregularly were less likely to report having HIV-positive gay friends (0·65; 0·43–0·97) or to disclose their sexual orientation to non-gay friends (0·59; 0·38–0·92). Compared with MSM who tested frequently, those who teested irregularly reported greater barriers to HIV testing (1·07; 1·01–1·13) and higher internalised homophobia (1·06; 1·01–1·11). Ordinal logistic regression showed HIV testing frequency was associated with HIV testing by sexual partners and good friends, knowing gay friends who were HIV-positive, discussing HIV with sexual partners, disclosing sexual orientation to non-gay friends, barriers to HIV testing, and internalised homophobia.Interpretation
Frequency of HIV testing could be improved among sexually active, HIV-negative MSM in Guangzhou, China. Enhanced interventions using HIV testing promotion via social networks, reducing structural barriers to HIV testing, and creating a gay-friendly environment could increase the frequency of HIV testing among MSM and increase the percentage of HIV-positive MSM receiving antiretroviral therapy, thus contributing to reducing HIV incidence in this population.Funding

Background
With the rapid pace of population ageing, tuberculosis in older people has become a public health challenge in China. However, the age-structured epidemiological transition and its impact on achieving the end tuberculosis targets by 2035 have not been understood well. We analysed the age-structured incidence and mortality of pulmonary tuberculosis reported in China to inform current and future control programmes.Methods
In this longitudinal study, we compared the trends of age-specific reported incidence and mortality of pulmonary tuberculosis from 2005 to 2015 in China. In addition to crude rates, we calculated age-adjusted rates from 2006 to 2015 by taking the population in 2005 as reference. We determined the annual crude and age-adjusted rates of reduction by fitting an exponential linear regression model, and extrapolated up to 2035 given fixed decline rates. All data were collected from national Infectious Disease Reporting System and Diseases Surveillance System.Findings
We noted overall downward trends of reported tuberculosis incidence and mortality in all age and sex groups since 2005, whereas the proportion of older people (aged 65 years and older) among reported patients with tuberculosis and deaths increased gradually. The total tuberculosis incidence and mortality were significantly higher in older people (193·0 cases per 100?000 people and 18·7 deaths per 100?000 people, respectively) than in younger groups (66·6 cases per 100?000 and 1·7 deaths per 100?000 people). The average annual decline in crude incidence was 4·2% (95% CI 3·5–4·9) and 5·1% (4·3–5·9%) in age-adjusted incidence; the annual decline in crude mortality was 9·7% (95% CI 8·4–10·9) and 12·4% (10·9–13·8) in age-adjusted mortality. Extrapolating this trend, by 2035, the crude incidence of tuberculosis was expected to reach 26·8 cases per 100?000 people and the age-adjusted incidence to reach 20·6 cases per 100?000 people, which would result in a total reduction of 57·8% and 65·0%, respectively, compared with the rates in 2015. By 2035, the crude mortality was expected to reach 0·33 deaths per 100?000 people and the age-adjusted mortality to reach 0·15 deaths per 100?000 people, which would result in a total reduction of 86·0% and 92·0%, respectively, compared with the rates in 2015.Interpretation
These findings demonstrated an age transition of tuberculosis epidemic and the effects of population ageing on slowing down tuberculosis control progress made in China. An average 6–7% reduction would be cancelled out by 2035 given current tuberculosis decline trend and demographic change. An enhanced surveillance with age-sensitive analysis of patients with tuberculosis and a targeted response are needed.Funding

Background
West China exhibits poorer newborn health outcomes than in other parts of mainland China. Therefore, we aimed to investigate the effect of the Early Essential Newborn Care (EENC) on neonatal outcomes in west China.Methods
We did an observational study of 14 counties in three west provinces of China. Licensed doctors, nurses from obstetrics and paediatrics, and midwives in each county were trained by experienced EENC facilitators. 3 months after the first EENC coaching, we did a quality control assessment to examine the effects of the EENC coaching. We examined hospitals that had the highest number of births in each county and selected post-partum mothers to be interviewed and have their medical records checked by convenience sampling. Institutional ethics approval to do this study was obtained from the Institutional Review Boards at National Centre for Women and Children's Health Care, Chinese Center for Disease Control and Prevention. We obtained written informed consent from all participants.Findings
Between March 25, 2018, and May 5, 2018, we examined 14 hospitals with the highest number of births in each county, of which we selected 126 post-partum mothers. EENC has turned out to be a useful and practical tool in west China. Out of the core interventions, some practices were relatively easy to implement, such as no routine suctioning for newborn babies (increasing from 0 at baseline to 100% after EENC coaching) and bathing after 24?h of birth (from 24% to 85%). However, hospitals encountered different kinds of difficulties in the EENC implementation. For example, 90 min of skin-to-skin contact was often interrupted because of inadequate facility resources (increasing from 0 to 62%). It was also noticed that hospitals that could guarantee 90 min of skin-to-skin contact could ensure early breastfeeding initiation (p=0·002), and successful first-time breast milk intake is associated with exclusive breastfeeding from birth till interview time (p=0·001).Interpretation
Hospitals need to remove all the obstacles and emphasise on the EENC recommended practices, including receiving 90 min of uninterrupted skin-to-skin contact within 1 min of birth, initiation of early and exclusive breastfeeding, and the use of neonatal nasal intermittent positive pressure ventilation. Additional communications should be encouraged among medical professionals from different regions, so ideas could be shared.Funding
