Safe-Sex Behavioral Intention of Chinese College Students: Examining the Effect of Sexual Knowledge Using the Theory of Planned Behavior

Numerous contemporary studies have examined safe sexual behavior among college students. In China, families are reluctant to discuss sexual behavior, thus understanding and exploring the sexual knowledge of college students and the promotion of safe sexual behavior is essential. On the basis of the theory of planned behavior (TPB), a cognitive behavioral theory that is widely used to predict human social behavior, we conducted an in-depth investigation of the factors influencing the sexual behavioral intentions of Chinese college students. We referenced the relevant literature to develop a TPB-based model for analyzing differences in sexual knowledge. Our statistical analysis revealed the following: (1) subjective norms and behavior control are key variables that influence the safe sexual behavior of college students; (2) attitudes and safe-sex behavioral intentions are influential in groups with extensive sexual knowledge; (3) behavioral control and subjective norms influence the differences in the comparative sexual knowledge of students. On the basis of the present results, we propose research recommendations and directions for the development of sex education in China.

Safe Sexual Behavior Intentions among College Students: The Construction of an Extended Theory of Planned Behavior

Sexual health education is an essential part of quality-oriented education for college students. It aims to help these students to acquire knowledge of sexual physiology, sexual psychology, and sexual social norms that is consistent with the maturity of the students. Along with college students’attitudes toward sex, their perceptions regarding sexual behavior have also undergone profound changes. The importance of safe sexual behavior, sexual taboos, and sexual autonomy are gaining increasing attention as Chinese society is becoming more open. For college students who have just reached adulthood and have full autonomy of themselves, however, are they really going to have sexual behavior without careful consideration? Or is it something they have planned to do in the first place? To answer the above questions, this study was conducted to understand the relationship between college students’ attitudes toward sex, subjective norms, and behavioral control of their sexual behavior intentions by applying the Theory of Planned Behavior. In this study, 460 valid questionnaires were collected from Chinese college students and analyzed with partial least squares structural equation modeling (PLS-SEM). This study analyzes the relationship of multiple factors, including those influencing college students’ sexual behavior intentions. Meanwhile, it also compares the differences in factors affecting sexual behavior intentions between college students with or without sexual experience and those of different genders. Based on the results of the study, it was found that, first, subjective norms and perceived behavioral control of college students had a significant effect on safe sexual behavior intentions, while attitudes did not have a significant effect on safe sexual behavior intentions. Second, the gender and sexual experience of college students had a significant effect on safe sexual behavior intentions. Third, non-sexually experienced college students were more likely to be influenced by external factors. Relevant future research suggestions will be proposed based on the results of this study. Finally, this study helps to provide substantive suggestions for enhancing safe sexual behavior among college students in the context of universal higher education, as well as strengthening the self-protection of college students and providing practical advice for the development of sex education in China.

Knowledge-attitude-practice survey among Portuguese gynaecologists regarding combined hormonal contraceptives methods

ABSTRACT Objectives To evaluate knowledge, attitude and practices of Portuguese gynaecologists regarding combined hormonal contraceptives. Methods A cross-sectional survey was conducted among 303 gynaecologists. Results Ninety percent of the gynaecologists considered that deciding on contraceptive methods is a process wherein the woman has her say. Efficacy, safety and the woman's preference were the major factors influencing gynaecologists, while efficacy, tolerability and ease of use were the major factors perceived by the specialists to influence the women's choice. Gynaecologists believed that only 2% of women taking the pill were 100% compliant compared to 48% of those using the patch and 75% of those using the ring. The lower risk of omission was the strong point for the latter methods. Side effects were the main reason to change to another method. Vaginal manipulation was the most difficult topic to discuss. Conclusions Most gynaecologists decided with the woman on the contraceptive method. The main reasons for the gynaecologist's recommendation of a given contraceptive method and the women's choice were different. Counselling implies an open discussion and topics related to sexuality were considered difficult to discuss. Improving communication skills and understanding women's requirements are critical for contraceptive counselling.

PCOS in adolescents

Polycystic ovary syndrome (PCOS), a heterogeneous syndrome of unknown aetiology, is the leading cause of anovulation, hirsutism and infertility in women. This multifactorial syndrome emerges at puberty and has cardiovascular and metabolic sequelae through menopause. The common features of normal puberty, namely menstrual irregularities and insulin resistance, obscure the diagnosis of adolescent PCOS, while there are no established diagnostic criteria for PCOS in this age group. The clinical implications of PCOS diagnosis in adolescents remain unclear. Experts in the field still ponder whether PCOS should be managed at such a young age with a view to hindering the long-term sequelae of the syndrome.
