Taking Meteorological Knowledge official micro-blog "Meteorological Knowledge" and Beijing Meteorological Bureau official micro-blog "Meteorology Beijing" as the research objects, the differences of different types of meteorological government micro-blog and the contribution of each factor were analyzed by comparing changes of the number of fans, micro-blog comments and forwarding and other key elements during March 1 to May 31 in 2012. The results showed that the number of fans was one of important indexes to determine the influence of meteorological government micro-blog, and the high active fans played a more prominent role. During the period of study, the fans number of "Meteorology Beijing" was far more than "Meteorological Knowledge", the daily micro-blog released number and comment forwarding number were both more than "Meteorological knowledge", but the proportion of active fans o f "Meteorological knowledge" was larger than "Meteorology Beijing". Timeliness was of greater contribution to advancing the meteorological government micro-blog influence. During the period of study, the proportions of comments and forwarding number of morning weather forecast were the largest, the evening weather forecast took the second place, and the noon was the smallest. But the influence of noon weather forecast micro-blog increased most highly approximately by 15% because of the higher timeliness. The content and form also made great contribution to the influence of meteorological government micro-blog. Comparison of diiferent types of meteorological micro- blog showed that, the number of fans and the influence of meteorological government micro-blog which mainly published real-time meteorological information were larger than which mainly published meteorological popular science knowledge.

Background: Early detection of HIV infection enables timely care and treatment. However, many men who have sex with men (MSM) remain unaware of their HIV status because they do not or are unable to access HIV testing services. Oral fluid HIV rapid tests have the potential to increase HIV testing. This study is the first to evaluate willingness to use the oral fluid test among MSM in China. Methods: A cross-sectional study was conducted in Beijing from July to October, 2012. Data were collected by self-administered questionnaires. Results: Of 262 who participated in the survey, 223(85.1%) reported that they were willing to use the oral fluid HIV rapid test. Willingness to use the oral fluid test was associated with higher education (adjusted odds ratio (AOR): 2.40, 95% confidence interval (CI): 1.13–5.10), lack of unprotected anal intercourse (UAI) with male partners in the past one month (AOR: 2.38; 95% 95%CI: 1.15–4.95), having taken more than 4 HIV tests (AOR: 3.54; 95%CI:1.52–8.28), and having ever heard of the oral fluid HIV rapid test from gay friends or gay organizations (AOR: 3.24, 95%CI: 1.40–7.51). Among those who expressed willingness to use the oral fluid HIV rapid test, the median amount of money they were willing to pay was 8 dollars. Among the 39 participants who were unwilling to use the oral fluid test, 79.5% (31/39) expressed concerns about the accuracy of the oral fluid HIV rapid test results and 17.9%(7/39) reported that they were not familiar with the oral fluid test and did not know how to use such a test. Conclusions: A high proportion of MSM in Beijing appear to be willing to use the oral fluid HIV rapid test. Appropriate cost and education measures could help improve acceptance of the oral fluid test. [ABSTRACT FROM AUTHOR]

Objectives The prevalence of sexually transmitted infections (STIs), including HIV, among men who have sex with men (MSM) has risen in China, mainly due to unprotected sexual intercourse. Migrant MSM might be more vulnerable to the risk of STIs/HIV because of their low socioeconomic status. This study aims at exploring the correlates of consistent condom use among young migrant MSM (aged 18-29 years) in Beijing. Methods Multivariate logistic regression analysis. Results The mean age of the sample was 23.7 years. Rural-to-urban migrant MSM accounted for 46% of the sample, and urban-to-urban migrant MSM for 54%. Of 307 migrant MSM, 178 (54%) reported having used a condom every time in the last three sexual episodes with both stable and casual sexual partners. Multivariate logistic regression analysis showed that MSM who had a low monthly income, had often experienced alcohol intoxication, did not use a condom at first sex, and had fewer lifetime male sexual partners were less likely to use condoms consistently. Conclusions Consistent condom use among young migrant MSM was relatively low and was associated with socioeconomic status and alcohol use. Future STIs/HIV prevention programmes should strengthen empowerment, access to condoms, and reduction of alcohol consumption within this socio-economically marginalised group. [ABSTRACT FROM AUTHOR]
