Prevalence and correlates of sexual behaviors among university students: a study in Hefei, China
BMC Public Health volume 12, Article number: 972 (2012)
In China, sexual health and behaviors of young people have become a growing public concern but few studies have been conducted to investigate the prevalence and psychosocial correlates of the phenomenon.
A self-reported questionnaire survey on youth sexual behaviors was conducted among 1,500 university students in 2011 at Hefei, a middle-size city in eastern China. A total of 1,403 students (age = 20.30 ± 1.27 years) completed the questionnaire with a high response rate of 93.5%.
Among the respondents, 12.6% (15.4% of male versus 8.6% of female) students reported having pre-marital heterosexual intercourse; 10.8% (10.5% of males versus 11.2% females) had oral sex; 2.7% (3.4% of males versus 1.7% females) reported same-sex activities; 46% (70.3% of males versus 10.8% of females) reported masturbation behaviors; 57.4% (86.2% of males versus 15.6% females) students viewed pornography. In terms of sexual communication about sexual knowledge acquisition, 13.7% (10.7% of males versus 18% of females) talked to their parents about sex; 7.1% (6.1% of males versus 8.4% of females) students reported having conversation with parents on contraception. About forcing sexual behavior, 2.7% (4% of males versus 0.9% of females) reported forcing their sexual partners to have sex, and 1.9% (2.4% of males versus 1.2% of females) reported being forced to have sex. Gender was found to be significant predictor of sexual behaviors in university students: males reported more sexual behaviors including sexual fantasy, heterosexual intercourse, masturbation, viewing pornography and talking about sex with friends. Several correlates of sexual behaviors were identified for students of different gender separately. For males, having romantic relationships, past sex education experiences, low educational aspirations, time spent on the Internet, and urban native settings were significantly associated with more sexual behaviors. For female students, having romantic relationships and urban native settings predicted sexual behaviors.
Sexual behavior among University students in China is not uncommon, although there are limited ways for students to acquire sex-related knowledge: male students showed significantly more sexual behaviors than female students. Having romantic relationships and more time spent online were important predictors of sexual behaviors among university students. To guide healthy sexual behaviors in young people, comprehensive sex education programs that provide necessary sexual health knowledge about safe sex should be developed and implemented in universities in China, particularly for students who have romantic relationships and those who spend long periods of time on the Internet.
Young people are at the beginning of their sexual and reproductive lives. How they are prepared for this journey has tremendous implications for their future lives and the health of the next generation. Sexual behaviors refer to a variety of sexual acts, such as talking about sex, solitary masturbation, intimacy, and sexual intercourse through their experiences and expressing their sexuality. Youth sexual behavior is highly relevant to different public health problems [1, 2]. For example, youth unprotected sexual intercourse contributes to unwanted pregnancies, abortions, pregnancy related complications, and sexually transmitted infections (STIs) including HIV/AIDS . While there are numerous studies on sexual behaviors and health among young people in Western countries, such investigations have been rare in different Chinese communities. Understanding the prevalence and psychosocial correlates of sexual behaviors in young Chinese people would provide important information on the development and implementation of effective sex education programs in China and thus help Chinese youth develop healthy and safe sexual behaviors. As such, the present study aims to investigate the prevalence and psychosocial correlates of sexual behaviors in young Chinese people based on a large sample of University students in Hefei, a typical middle-sized city in China.
In recent decades, a large number of studies have examined the prevalence of youth sexual behaviors usually in multiple aspects of heterosexual and homosexual intercourse, sexual coercion, masturbation, and pornography viewing in Western countries . For example, a study found 80% of the males and 73% of the females had experienced heterosexual intercourse in United States . Overall, 74% of university students reported ever having had sexual intercourse in Turkey . A report conducted among 8658 American university students found 5% students had sexual experiences with members of their own sex . Worldwide evidence shows that the experience of sexual coercion is fairly prevalent among young people. Approximately 25–33% of college women in the United States reported experiencing forced touching of sexual parts and around 10% of college women reported experiencing forced oral, anal, and/or vaginal intercourse . It was found that 92% of men and 77% of women university students had masturbated in the United States . In Denmark 97.8% of males and 79.5% of females watched pornography among 1002 people aged from 18–30 years old .
In China, a limited number of studies have attempted to examine the occurrence of sexual behaviors in university students in the past two decades. In 1989, a general survey on university students’ lives was conducted in Beijing, which revealed that around 13% of male students and 6% of female students had encountered sexual experiences . In 1992, a similar study in Shanghai indicated that 18.8% of male university students and 16.8% of female students had engaged in premarital sex . In 2000, a nationwide survey involving over 5000 participants from 26 universities in 14 provinces revealed that 11.3% of university students experienced sexual intercourse . Meanwhile, a multi-year longitudinal study in Beijing revealed that the percentage of premarital sex among university students rose from 16.9% in 2001 to 32% in 2006 . While these results provided useful information about the general situation of sexual behaviors in Chinese university students, most studies only adopted single-item “Yes” or “No” questions to obtain information regarding whether the student had sexual intercourse or not. Multiple aspects of sexual behaviors, such as same-sex sexual contact and sexual communication, are unknown. Obviously, such studies cannot provide a clear picture about Chinese university students’ sexual behaviors in different aspects. Therefore, there is a critical need to further investigate this phenomenon by using comprehensive assessment tools which can assess multiple dimensions of youth sexual behaviors in China.
Several important predictors of youth sexual behaviors have been reported by Western researchers. A study revealed students with lower grades, compared to those with higher grades, were more likely to have sexual intercourse experience in high school . College students from the cities and towns were more prone to sexual intercourse than those from a rural area . In high school, teenagers with bad school achievements were more likely to have already lost their virginity and engage in more sexual activities than those who achieved academic success . In terms of sex education, it has been a controversial subject in some countries for a long time, such as the USA and China. A large number of studies conducted across the world examined it and its association with youth’s sexual behaviors. Some found sex education may reduce the level of sexual activities and risk sexual behaviors . Some findings found that sex education might not cause any sexual behavior changes . Studies commonly demonstrated that among adolescents and young people, being in a romantic relationship is significantly associated with an increased likelihood of sexual initiation and sexual activities . Also, exposure to the Internet and the messages they present are greatly influential factors on American adolescents . Although studies have yielded valuable information to understand psychosocial correlates of sexual behaviors among adolescent and young people, most of such studies were conducted with western contexts. There is no research examining whether and how these factors also affect Chinese university students’ sexual behaviors. The present study was the first study to attempt to explore psychosocial correlates of sexual behaviors based on Chinese context.
Furthermore, factors that affect sexual behaviors appear to be different for males and females. Many studies in western countries indicate that males are more likely to initiate sexual intercourse, higher prevalence rate, more frequent sexual behaviors and significantly higher risk behavior than girls [22, 23]. Males were more likely to report having lost their virginity and having initiated sexual intercourse in earlier age and more sexual partners than females . Young people often learn from experience, and their experiences may influence their subsequent behavior. This process may vary for male and female youth, since society often places different meanings on sexual activity for males and females. For example, stronger social and emotional sanctions have been associated with sexual activity for females than for males . Males tend to receive more permissiveness from society for premarital sexual activity than females. Given that sexual behaviors have different implications for males and females, psychosocial factors associated with sexual behaviors will vary as well. However, it is unclear how gender differences on prevalence of sexual behaviors are; what and how psychosocial factors linked to sexual behaviors for Chinese male and female students. Thus, it is necessary to explore how gender differences on prevalence of sexual behaviors; what and how psychosocial factors were associated with sexual behaviors for males and females, respectively.
Against the research background, the present study was designed to address three primary research questions: (a) how prevalent are sexual behaviors among university students in Hefei. (b) What are the gender differences in prevalence of sexual behaviors? (c) What are the factors associated with sexual behaviors for males and females, respectively?
Procedure and participants
The present study was conducted in Hefei, a typical middle-size city in Eastern China in September, 2010. There are nine comprehensive public universities in Hefei, covering a wide range of disciplines such as science, education, law and literature. From the nine universities, four universities were randomly selected, among which 16 classes was selected from four different grades purposely based on the criterion that there are similar numbers of male and female students in the class (the ratio of male to female ranging from 1:1.5 to 1.5:1). Specifically, at each grade in each university, one class was sampled. All students in the selected classes (n = 1,500) were invited to participate in this study and all of them agreed to be participants by signing up a consent form before the questionnaire survey. Of the 1,500 respondents, 1403 students returned completed questionnaires, indicating a high response rate of 93.5%. Student ages ranged from 18 to 25 years (M = 20.30, SD = 1.27), with 59.2% being males and 40.8% being females. Detailed demographic characteristics of the participants are summarized in Table 1.
The questionnaire survey was conducted by the first author and a trained research assistant in classroom settings with standardized instructions. At each measurement occasion, the purposes of the study were introduced and confidentiality of the data collected was repeatedly ensured to all participants. To maximize the validity of these self-report data, several measures were performed. First, spacious classrooms were used for the survey and students were arranged to sit separately. Specifically, at each survey occasion, a 100-seat lecture hall was provided for no more than 40 students to complete the questionnaire. Second, the first author and the research assistant were present throughout the administration process to answer possible questions. No teachers of the classes or the universities showed up throughout the survey. Third, students were required to focus on their own questionnaires and not allowed to discuss with other students. Fourth, students were encouraged to answer the questions in an honest way and assured repeatedly that their results would be analyzed in an aggregated manner with personal information being kept in strict confidentiality.
This study and data collection procedure has obtained approvals from the surveyed Universities administration committee and human research ethics committee at the University of Hong Kong.
The first section of the questionnaire consists of questions about the participants’ gender, age, grade (Year 1 to Year 4), study discipline (Science or Art), educational aspiration, romantic relationship experience, sex education experience and the amount of time spent online and area. For educational aspiration, students were asked to indicate which degree they want to achieve in terms of bachelor’s degree, master’s degree, and PhD degree. Two “yes” or “no” questions ask students whether they have any romantic relationships now or in the past; and whether they received sex education before or currently (sex education referred to formal or informal education including courses, workshops, seminars). For time spent online, students were required to report the average number of hours per day they spent on the Internet. One question asked students where they grew up, whether it was in an urban or rural area.
Sexual behavior measure
In this study 20 multiple-choice items from Sexual Behavior Inventory of SKAT were used to investigate Chinese university students’ sexual activities in the last year. Sexual behavior Inventory was developed by Lief in 1990  and revised by Fullard, Scheier, & Lief in 2005 , which is a developmentally appropriate, paper-and-pencil self-report questionnaire for obtaining information about a wide variety of sexual and experiential behaviors relevant to adolescent sexuality and education. The 20 multiple-choice item-questionnaire intended to elicit information about a variety of sexual acts that included kissing, fondling, sexual communication (e.g., talking with your boyfriend/girlfriend about sex), intercourse (e.g., sexual intercourse with a person of the opposite sex), and forcing sex. Respondents answered on a Likert scale (1 = Never, 2 = Less than monthly, 3 = monthly, 4 = weekly, 5 = daily). Higher total scores indicated having more sexual activities. In order to fit with a Chinese context, the scale was translated and back-translated firstly by two expert bilingual (English and Chinese) (one male and one female) speakers, and then was revised in 14 university students focus group interviews and by 5 expert reviewers, and finally the pilot test with 400 university students samples was conducted in order to gain support for reliability and validity. Finally, 2 items (“Going home with a stranger you have met at a party or bar” and “Go on a date with a group of friends”) were irrelevant to Chinese context were deleted and the uni-dimensional Chinese sexual behavior scale with 18 items was developed. The internal consistency of the questionnaire in this study was Cronbach’s alpha = 0.84.
First, frequencies and percentages for each item of the sexual behavior questionnaire were computed to provide a descriptive profile on the prevalence of sexual behaviors among Chinese university students. Second, individual sexual behaviors were compared between male students and female students by independent t-tests to examine gender differences. Thirdly, regression analyses were performed to identify factors that contributed to the occurrences of sexual behaviors, in which participants’ total score on the sexual behavior questionnaire served as dependent variable; age, grade, educational aspiration, romantic relationship experience, sexual education experience, original place/area, and time spent online served as independent variables with gender as selection variable. All analyses were performed using SPSS for Windows, version 17.0.
Prevalence of sexual behaviors
Table 2 displays the prevalence of sexual behaviors in an overall sample in the last one year. A small number of students (10.8%) engaged oral sex and a small number of students (12.6%) had heterosexual intercourse. A few students (2.7%) had same-sex sexual activity, around 46% students had masturbation and more than a half of students (57.4%) viewed pornography movie/video in last one year. In terms to sexual communication, 75.6% students talked about sex with their friends. However, students who talked with parents about sex and contraception accounted for only 13.7% and 7.1%, respectively. In terms of forcing and being forced to have sex, 2.7% students forced a sexual partner to have sex and 1.9% students were forced to have sex in the last one year.
Gender differences in prevalence of sexual behaviors
There was a varying degree of statistically significant gender differences between male and female group in sexual acts within the last one year. There were strongly significant gender differences in some aspects of sexual behaviors. Males reported more sexual fantasies (84.6%), solitary masturbation (70.3%), and using pornographic videos (86.3%) and magazines (53.6%), talking about sex with friends (85.9%) and sexual fantasies (84.5%) than females (36.1%, 10.9%, 15.6%, 9.3%, 85.9%, and 36%, respectively). There was a moderately significant gender difference in talking with friends about contraception, showing males were more likely to talk with friends about contraception (57.4%) than females (40.4%). Females reported slightly more dating (49.1%), kissing (42.7%) and fondling (29.9%) than males (51.7%, 32.4%, and 26.5%, respectively). It seems males were somewhat more likely to report sexual practices than girls were. And females tended to report more intimacy than boys did (Table 3 and Table 4).
Factors correlated with sexual behaviors by males/females
Linear regression analyses were performed to examine factors (age, grade, discipline, education aspiration, romantic relationship, sex education experience, rural/urban area and time spent online) linked to sexual related behaviors for male and female students, respectively. The analysis found that five factors for males were significantly associated with sexual behaviors in last one year: romantic relationship (β <−.29, p < 0.001), received sex education (β < −.13, p < 0.001), education aspiration (β < −.09, p < 0.05), time spent online (β < .09, p < 0.01) and area (β < −.07, p < 0.05). The five factors could explain 19% of males’ sexual behaviors. Two factors for females were significantly correlated with sexual behaviors: romantic relationship (β < −.46, p < 0.001) and area (β < −.09, p < 0.01). The two factors could explain 27% of females’ sexual behaviors. Age, grade and discipline were not significantly associated with sexual behaviors in both male and female group (Table 5).
The present study found that rates of heterosexual intercourse reported by the university students in Hefei who responded to our study were 12.6% (15.4% males and 8.5% females). These rates fall within the ranges reported by Chinese university students in other Chinese cities since 1995 [16, 28, 29]. During the last decade, the rates of heterosexual intercourse among Chinese university students do not appear to have undergone a dramatic change, remaining the similar with or no big different from rates observed in neighboring regions or countries. For example, it was reported that 22% of never married youth aged 20 years having had sex in Taiwan in 2004 . And in the Survey Assessment of Vietnamese Youth conducted in late 2003, it was found that 16.7% male and 2.4% female aged 18 to 25 years engaged sexual intercourse . It may be because the regions in Asia, such as Taiwan, Korea, Vietnam and Japan, share the same Confucian-based traditional culture expecting in terms of sexuality that men and women should conduct themselves properly from an emotional distance at all times and not have any contact before marriage . Although they have been open to outside influences socially, culturally and economically for different periods and in different ways, their sharing traditional culture still rooted in societies deeply. Compared to western countries, the percentage in China remained much lower than rates observed in the USA that 80% of male university students and 73% of female university students had heterosexual intercourse and in Scotland that around 74% university students had heterosexual intercourse during the 1990s and early 2000s [33, 34]. This may be related to vast differences in cultural and social context. A specific example is that the Chinese Ministry of Education prohibited marriage among university students until 2005 and the universities offer a context which discouraged university students’ sexual activities. In China, many universities have direct and indirect regulations that limit intimate relationships between students of opposite sex in school. For example, every student must live in school and males were not allowed to enter female dormitories; students must come back to the dormitory before 10:30 pm since the gates of dormitories usually close at 10:30 pm, with the lights turned off at 11:30 pm. In addition to heterosexual intercourse, our results also clearly indicate that there were other acts among university students, with both male and female students having oral sex, the same-sex activities, and forcing and being forced to have sex. The results may indicate that sex education not only advocates abstinence as a good way for safe sex, but also provides comprehensive sex education including sexual knowledge about reproductive health, condom and contraception use, proper and responsible sexual attitude for protective, and safe sex behaviors among young people.
There are six items in the sexual behaviors questionnaire asking students about their communication with other people on sexual topics or other ways of acquiring sexual knowledge (e.g., viewing pornography videos or magazines). With respect to communication on sexual topics, the results of the current study suggest that parent-adolescent communication on sex was quite infrequent in China than in Western countries. A study conducted in Sweden reported that 40% of male and 60% of female high school students had talked with their parents about sex . However, in the current study, only 13.7% (10.7% males and 18% females) students talked with parents about sex, and only 7.1% (6.1% males and 8.4% female) students talked with parents about contraception in the last one year in China. Given the important role parents play in adolescents’ life , parental involvement in adolescent sex education needs to be enhanced. For example, parents should be encouraged to communicate with and educate children about sex in an environment of openness when they are most drawn to sexual behaviors during their adolescence. The study also revealed the large proportion of students, especially male students, who saw pornography such as books/magazines/videos/websites. It may suggest that pornography may be a ready source of basic information about sex for Chinese youth and may have had some influence on respondents’ sexual practices. It becomes quite necessary to incorporate pornography topics in sex education for university students in China . For example, educating youth about the realism of pornography and the relationship between media and life; encouraging students to reflectively think and discuss what the possible benefits and harmful effects of pornography are for young people, why people use it, and what the law says about it.
This study found significant gender differences (male > female) in prevalence of heterosexual intercourse, masturbation, sex fantasies, exposure to pornographic media; these differences were consistent with previous studies done in China and USA [29, 36, 37]. The difference of heterosexual intercourse may be explained by noting that whereas premarital heterosexual intercourse for boys is considered a socially acceptable rite of passage, girls tend to be labeled and stigmatized and are often blamed for sexual encounters that could result in pregnancy and sexually transmitted infections . Attitudes and beliefs from family and society still expected men to take responsibility for initiating and ending sexual activity. Women are expected to be virgins before marriage and less sexually initiating than men [14, 39]. Gender differences in sex fantasy, masturbation and pornography use may also be partially due to sex drive. Research suggests that men on average have a stronger sex drive and are more aroused by pornography than women do . Alternatively, the large gender differences in sex fantasy, masturbation and pornography use may be explained by socially desirable responding. Stigma continues to be associated with female autoerotic behaviors particularly in different Chinese communities; therefore, women may underreport rates of masturbation or pornography use .
Consistent with previous studies, it was found that the incidence of sexual behaviors in the past year for university students were positively related to having romantic relationship experience, received sex education, lower education aspiration, longer time spent online and living urban area for male and having romantic relationship experience and living in urban area for female.
Among all the factors identified predicting university students’ sexual behaviors, having romantic relationship experience had the strongest explanative power for both male and female. Several studies have evidenced that dating, especially steady romantic relationship is a prominent factor associated with sexual behaviors. Having a boyfriend or girlfriend may increase the opportunity for engaging in intimate and precoital behaviors, such as kissing and fondling, which may be followed by sex. Furthermore, having a boyfriend or girlfriend may expose a youth to a new set of friends, who may share more permissive norms about sex; many studies have demonstrated that youth whose peer norms encourage sexual activity have an increased likelihood of being sexually active. Thus, young people in romantic relationships have extra need for information about intimacy and sexual risk and safety. The study suggests the importance of targeting education efforts toward young people in romantic relationship . Schools and parents should help young people, in particular those in romantic relationship, to develop skills and abilities in relationship and intimacy including teaching sexual health knowledge, advocating safe sexual behaviors, and to make rational sexual decision.
Received sex education has the second most influential source to explain male students’ sexual behaviors. For males, students with received sex education showed significantly more sexual behaviors than those without such experiences. This seems to be inconsistent with the “good intention” of Chinese mainstream society that sex education should delay sexual initiation and decrease sexual activities among adolescents and young adults . However, it seems that recent data have shown that the “good intention” did not protect young people better [43–45]. On the other hand, sex education subjects are elective courses in Chinese universities. It is also possible that students who are interested in sexuality or have sexual experiences are more likely to choose the related subjects. Relationship between sex education and adolescents’ sexual behaviors is complex . What role does sex education play? The researchers agree with Pan’s point of view: “Sex education neither alone plays ‘fire extinguisher’ role, not functions as ‘accelerant’; the ultimate goal of sex education is to help all individuals, especially the next generation, enjoy a ‘happy sex life’ as much as possible .” Namely, sex education should assist young people in developing a positive view of sexuality, provide them with information they need to take care of their sexual health, and help them acquire skills to make decisions now and in the future. However, considering China’s lack of an open and free social climate which normally plays a very important role in promoting sex education, it is very important to use the university system to introduce sexuality. Firstly, the university system appears to be a “safe” place or platform to incorporate debates and understandings of sexualities. Universities also have much more freedom to talk about sexuality than other places; therefore, debates can be deeper and more analytical. Furthermore, university students tend to be more open and to more easily adopt new ideas and perspectives on sexualities .
Another factor correlated with sexual behaviors was educational aspiration for males. We found that education aspiration could negatively predicted male students’ sexual behaviors, namely the higher education aspiration, the less sexually active. The finding further confirmed prior studies that commitment to doing well in academic protected respondents from becoming sexually active and more sexual partners . Finally, time spent online was the last factor correlated with sexual behaviors for males. Our study found time spent online could slightly predict male students’ sexual behaviors, namely the longer surfing internet time, the more sexually active. But it couldn’t predict female students’ sexual behaviors. This may be because male students reported much higher rates of visiting pornographic websites, partner seeking and engaging online risky behaviors, which was closely associated with sexual behaviors including risky sexual behaviors . Appropriate guidance on their Internet use will be needed in China regarding the possible future impact of the Internet and pornographic media on the sexual behaviors of young people. For example, carefully monitoring and reducing online sexual risk behaviors among youth, especially males, and properly utilizing Internet as an informative source for sex education.
This study had several limitations. First, its cross-sectional design prevented us from identifying cause-and-effect associations, such as whether education aspiration decreased the prevalence of male students’ sexual behaviors could not be determined in this study. Second, the results obtained in this study should not be generalized to all Chinese young people or to all Chinese university students, since our sample was limited to university students within one capital city and socio-demographic characteristics are greatly diverse within Chinese provinces. Finally, the possible bias introduced by under-reporting should be noted. Measurements of sexual activity in this study were based on self-reports and participant sensitivity, especially female students, regarding sexual behavior may have led to under-reporting because of social desirability effect. Social desirability scale may be included in future survey.
Our results revealed that the frequency of sexual activities among university students in Hefei varied with varying degree of gender differences, such as masturbation, seeing pornography, heterosexual intercourse and sexual communication. Moreover, our results showed that sexual behaviors were significantly predicted by romantic relationship, received sex education, education aspiration, time spent online and area for male students, and romantic relationship and area for female students. This information is important for policy makers and sex educators to develop effective and feasible strategies targeting at promoting sex education for Chinese university students.
