Pornography Consumption, Sexual Attitude, and Condomless Sex in China.

Studies have found that pornography consumption is associated with a higher likelihood of having condomless sex. Past research was primarily conducted with Western populations from developed countries. Consequently, less is known about sexual and reproductive health in developing countries and regions. A national sample of 11,957 university-level students was used to investigate the association between pornography consumption, sexual attitudes, and condomless sex. Our findings suggest that a higher frequency of pornography consumption is associated with an increased likelihood of having condomless sex and more positive attitudes toward premarital sex and one-night stand.

A Chinese Conceptual Semantic Feature Dataset (CCFD).

Memory and language are important high-level cognitive functions of humans, and the study of conceptual representation of the human brain is a key approach to reveal the principles of cognition. However, this research is often constrained by the availability of stimulus materials. The research on concept representation often needs to be based on a standardized and large-scale database of conceptual semantic features. Although Western scholars have established a variety of English conceptual semantic feature datasets, there is still a lack of a comprehensive Chinese version. In the present study, a Chinese Conceptual semantic Feature Dataset (CCFD) was established with 1,410 concepts including their semantic features and the similarity between concepts. The concepts were grouped into 28 subordinate categories and seven superior categories artificially. The results showed that concepts within the same category were closer to each other, while concepts between categories were farther apart. The CCFD proposed in this study can provide stimulation materials and data support for related research fields. All the data and supplementary materials can be found at https://osf.io/ug5dt/ .

Effects of Sexuality Education on Sexual Knowledge, Sexual Attitudes, and Sexual Behaviors of Youths in China: A Cluster-Randomized Controlled Trial.

PURPOSE: There is a lack of trained educators and age-appropriate teaching materials for sex education in China. This study aims to assess the effects of an internet-based sexuality education programme on sexual knowledge, attitudes, and behaviors among adolescents in China. METHODS: We undertook a multicentre, cluster-randomized controlled trial in 29 vocational high schools in Guangdong and Yunnan, China. Students in the intervention group received weekly sexuality education delivered over two months based on a sexuality education package named "You and Me". A questionnaire was completed at baseline by all students, after receiving a sexuality education by the intervention group, and once a year after receiving sexuality education by the intervention group or at a similar time point by the control group. RESULTS: Between October 2018 and December 2019, 3,151 participants from 29 schools/clusters were recruited, from which 1,760 students were randomly assigned to receive an eight-session internet-based sexuality education package. Significant improvements were observed for both sexual knowledge and sexual attitudes immediately after the intervention and one year after the intervention. However, no significant effects were observed for sexual behaviors. DISCUSSION: The internet-based sexuality education package was found to positively affect the sexual knowledge and sexual attitudes among adolescents, providing a potential solution to the lack of trained educators and teaching resources for implementing country-wide sexuality education in China. However, further research is still needed to determine the effects of sexuality education packages on sexual behaviors.
