BackgroundMen who have sex with men (MSM) are a high-risk group for sexually transmitted diseases (STDs) and human immunodeficiency virus (HIV) infection. In China, the vast majority of MSM feel forced to marry or plan to marry women, according to traditional Chinese culture. Women who have regular sexual relations with MSM, called tongqi in mainland China, live with a high risk of STDs or HIV infection, but these risks are often ignored. Our investigation of this group of the women is a preliminary study that aims to understand the sexual health problems of tongqi and related factors.MethodsThis study relied on website mobilization and was funded by tongqi. Participants were limited to women who had sex with MSM to whom they were married (in-GWs), whom they had divorced (ex-GWs), or with whom they were friends (GGFs). The data were collected using questionnaire software.ResultsA total 144 valid surveys were returned from 100 in-GWs, 33 ex-GWs, and 11 GGFs. Average respondent age was 32.8 ± 6.4 years (range 22 to 58 years). Among in-GWs and ex-GWs, over 95% learned that their husbands were MSM after marriage. More than half of respondents had had sex before marriage, and one-third of those women had sex partners other than their husbands. In addition, 35.3% of tongqi had STDs symptoms. About 50% participants had had oral sex with sex partners of MSM and 10% had had passive anal sex, with low condom use during both oral (9.7%) and anal sex (23.1%). Most tongqi had misunderstandings about STDs and HIV and less than 30% had undergone HIV screening. Among participants tested, 5.6% were HIV positive. A total 93.5% of respondents believed that laws should be established to protect the sexual rights of women.ConclusionsWomen who have regular sexual relations with MSM face adverse sexual health issues and are susceptible to STDs and HIV infection. Measures must be taken to protect the rights and interests of tongqi in mainland China.Electronic supplementary materialThe online version of this article (doi:10.1186/s12889-017-4096-z) contains supplementary material, which is available to authorized users.
During the COVID-19 pandemic, people have seen the precious value of park green space for health. In the post-COVID-19 Era, it is essential to understand the different needs and expectations of different communities for the use of park green space. A myriad of previous studies focused on the whole city’s demand for park green space, while few studies examined spatial equity from a supply-demand perspective. This paper aims to investigate the differences in park green space accessibility among people of different ages at a community scale. Specifically, to better evaluate the accessibility of park green space and account for the travel choice, we compared the effects of the two-step floating catchment area (2SFCA) method containing different distance decay functions (i.e., the improved 2SFCA methods) by considering the traffic network and the scale of park green space. In addition, we compared the improved 2SFCA methods with the traditional 2SFCA. This study investigated the spatial equity of park green space accessibility in 1184 communities with a total population of 6,468,612 in the central urban districts of Wuhan. The results showed that the high accessible communities were concentrated in the urban center along the Yangtze River. The improved 2SFCA methods outperformed the traditional 2SFCA, and presented smoother gradient information. It was revealed that over half of communities’ park green space accessibility levels did not match their population density. Inequality of accessibility to park green space was found in people of different ages, especially for the youth (Gini coefficient was as high as 0.83). The difference in the accessibility of urban park green space among different age structures implies the need to integrate community green space planning into urban planning in the post-COVID-19 Era.
