Masturbation and premarital sexual intercourse among college women: making choices for sexual fulfillment.

Given the potential value of masturbation as an alternative to high-risk sexual practices, there is a need to investigate factors surrounding this method of physiological sexual fulfillment. Therefore, this study examined the differences, if any, between women who have engaged in masturbation only (MO), both masturbation and sexual intercourse (MSI), and sexual intercourse only (SIO). An anonymous questionnaire was administered to volunteer respondents enrolled at a Midwestern university, yielding a subsample of 777 never-married, heterosexual women. Group comparisons indicated that MO Group women were most likely to feel guilty about engaging in masturbation and petting, but least likely to report either comfort with their sexuality or sexual satisfaction. MSI Group women indicated that, while growing up, they were less attached to their mother and father figures, whom they rated as uncommunicative. They also were more likely to have engaged in risk-related sexual behaviors. SIO Group women were more likely to have used contraceptives at first sexual intercourse and to report fewer lifetime sex partners than MSI Group women. Since a substantial number of college women refrain from engaging in masturbation, yet choose to have unprotected sexual intercourse and multiple sex partners, and others engage in masturbation but report experiencing guilt feelings regarding self-stimulation, it is of crucial importance that the negative connotations of masturbation and its attendant impact on sexual satisfaction be addressed by sexuality educators, clinicians, and researchers.

[Has the age of onset of sexual activity in youths changed in the time of AIDS? Literature review 1972-1992].

This article on the sexuality of adolescents (aged 16 to 20) presents results of a secondary analysis of Swiss studies completed on the subject between 1972 and 1992. The aim of the study was to follow up the evolution of three aspects of sexual behaviour since 1972 as a contribution to answering the following question: "What influence have the AIDS epidemic and the 'STOP-Aids' campaign had on the time of onset of sexual activity in young people?" Three aspects of sexual behaviour have been analyzed: 1. The proportion of young people who have already had sexual intercourse. This research shows that the percentage of sexually active 17-year-olds increased in the last 20 years for girls from 33% to 46% and for boys of the same age, from 23% to 51%. This increase took place before 1987. Since then, the proportion of sexually active young people of this age has not changed. 2. The number of life-time partners. In 1992, 28% of girls and 23% of boys aged 17 to 20 years had had more than 4 sexual partners. There had been no changes in these percentages since 1987. 3. The use of contraception. The use of contraception during the first sexual intercourse has become more frequent. In girls aged 16 to 20 years it rose from 47% in 1976 to 76% in 1992; in boys it increased from 50% in 1976 to 76% in 1992. For 17- to 20-year-olds, condom use with an occasional sexual partner rose from 16% in 1987 to 69% in 1992.(ABSTRACT TRUNCATED AT 250 WORDS)

Predictors of intention to be sexually active among Tanzanian school children.

This paper presents the results from a study of human immunodeficiency virus/AIDS risk behaviour conducted among primary school children in the Kilimanjaro and Arusha regions of northern Tanzania. The study was guided by the theory of reasoned action, and the decision to have or abstain from sexual intercourse was studied. All sixth and seventh grade pupils at eighteen schools were invited to participate. A total of 2,026 pupils (mean age 14.0 years) participated (participation rate of 85%), representing a wide variety of ethnic, socio-economic and urban-rural groups. Sixty-three percent of the boys and 24% of the girls reported having had their sexual debut. Attitudes, subjective norms and self-efficacy were all predictors of intention to have sexual intercourse within the next three months, but prior behaviour emerged as the strongest predictor of intention. Primary schools appear to be an important arena for HIV/AIDS education in Tanzania and it is recommended that such education be directed toward young adolescents.

Sexual activities of Malaysian adolescents.

This paper examines data on the sexual activities of 1,200 Malaysian adolescents aged 15-21 years based on a probability household sampled survey carried out in Kuala Lumpur in 1986. Sexual behaviours like premarital sexual intercourse, contraceptive usage and masturbation were presented. Of the 1,181 unmarried respondents, 9% (105) reported having had sexual intercourse; males were significantly more experienced compared to females. Older age groups were also found to be more sexually active than the younger ones. Among those who had experience dating (n = 521), 20% (105) have experienced sexual intercourse, 44% (228) have kissed and necked, and 35% (183) have experienced petting, while 24% (130) have had no physical intimacies. Poor use of contraception was also revealed. The most commonly used were condoms, oral contraceptives and withdrawal. With regard to masturbation, males begin this practice relatively earlier than females. Almost half of those who indulged in masturbation were worried by the act, especially the females. Implications of the findings are discussed.

Estimating sexual behaviour parameters in the light of AIDS: a review of recent UK studies of young people.

This paper reviews UK surveys of the sexual behaviour of young people since the advent of AIDS. The studies, which are restricted to those whose samples were intended to be representative of the general population, reveal broadly similar estimates of key sexual behaviours (numbers with sexual experience, numbers of partners, frequency of intercourse, condom use and anal penetration). In spite of these similarities and the usefulness of such information for estimating the potential rate of transmission of HIV a number of methodological issues continue to afflict this kind of research. The paper calls for standardized question formats and a centralized body to monitor changes in these parameters of sexual behaviour.

Peer counseling in a culturally specific adolescent pregnancy prevention program.

This study evaluated the effects of peer counseling in a culturally specific adolescent pregnancy prevention program for African American females. A random pretest and multiple posttest experimental and comparison group design was used to obtain data on a sample of 63 female African American adolescents, ages 12 to 16, who lived in four public housing developments. Descriptive data and tests of significance revealed that none of the participants who received peer counseling became pregnant within three months of the intervention. Findings revealed a statistically significant increase in reproductive and other self-related knowledge topics among the experimental group when comparing pretest and eight-week posttest scores. Most participants had not had sexual intercourse; the average age of sexual onset was 12 years in the experimental group and 11 years in the controls. Designing and implementing culturally specific adolescent pregnancy prevention programs for adolescents younger than age 11 and/or before sexually active seems appropriate.

Sexual behavior of American adolescents: results from a U.S. national survey.

PURPOSE: This paper reports on data from a 1990 U.S. national survey of the sexual behavior of male and female adolescents aged 12-17. METHODS: A household survey using a multi-stage area probability sample of the United States was undertaken in 1990. Adolescents were interviewed about sexual history, contraceptive use, and motivations, attitudes, and expectations with regard to sexual behavior and risk. RESULTS: The majority of 17-year-olds and about half of 16-year-olds, both male and female, had initiated sexual activity, with males initiating at younger ages than females. Sexual activity was episodic; only half of sexually experienced adolescents reported having sex in the month prior to the interview. Many sexually active respondents expressed less desire to have sex than confidence that they would have sex. Over half of respondents reported using a condom at most recent intercourse, with boys being more likely than girls to report condom use. Condom use at last intercourse was unrelated to perceptions of risk and concern about AIDS. CONCLUSIONS: Given the importance of some of the undesirable consequences of sexual activity in adolescents, such as AIDS and unwanted pregnancy, accurate and up-to-date information on sexual behavior of this age group is crucially important. The results of this study underscore the need for in-depth, population-based research on adolescent sexual behavior.

[Survey on sexual behavior by Congolese and French high-school students in an AIDS context].

The social and economic impact of AIDS add to those of a recent civil war in 1997. There were fratricidal confrontations before and after this period. Pointe-Noire, the second city of Congo and the economic Capital, was on the whole spared. We carried out a survey of 292 high-school students: 39% of girls and 61% of boys, from 14 old to 25 years old (average age of 19 years). They were from 5 general and technical schools, which are representative of the school recruitment of the city of Pointe-Noire. This study made in 1998 was the second part of a work achieved in France in 1997 with 1,859 high-school students: 70% of girls and 30% of boys, mean age 17.7 years, range 15-25 years. They came from 3 general, technical and professional schools of two departments of the region "Centre" ("Indre-et-Loire" and "Loir-et-Cher"). The material, corresponding to this study, is an anonymous self-questionnaire of 55 closed items presented in the form of assertions to which the student respond either yes or no. Items investigated: 1) pubertal maturation and subjective maturation; 2) different aspects of sexual experience in adolescence (components of sexual experience) [9] and 3) sexual behaviour (including sexual risk taking). All items have been formulated in the most accessible possible way for the youngsters. Previously, in 1996, we had made a pre-test with this material near sample of French people from 16 to 68 years old. The results of the study highlight that the Congolese youngsters present more risk than their French homologues. Although the pubertal status (the menarche and the spermarche) occurs slightly later, Congolese boys present a greater number of sexual partners and greater sexual precocity. Among 54% of Congolese pupils from the sample which had already had a sexual intercourse (68% of boys and 42% of girls) versus 52% of French pupils (58% of boys and 49% of girls), 88% of the Congolese boys have sexual intercourse at the age of 15, versus 72% of the girls at 16.5 versus 65% of the French boys in their 15.5 and 52% of the girls at 16. These differences are significant (p < 0.001) like all the following ones. Congolese students declare more sexual partners (4 during the last 12 months and 5 for all their life versus 3.2 and 4.4 for the French students); the boys more than the girls (6.5 sexual partners on the whole versus 3.7 for the girls in Congo and 5.7 versus 3.8 in France). Congolese girls generally have fewer sexual relations (over 12 months or during their entire life) than French high-school girls (respectively 5.9, 6.9 versus 8.7 and 9.3). We can see with French and Congolese students, a "traditional" dichotomy between boys and girls: that is to say girls tend to engage later in sexual relations and to favour the long and regular relations, while the boys have more short, and spaced sentimental relations. The relations of these last ones tend to evolve on a more preparatory mode, genital and intermittent, contrary to those girls who seem more sentimental and continuous. The use of the condom concerns 72% of the French pupils for the first sexual intercourse (74% of boys versus 72% of girls) - which is close to results of French reference surveys [1, 3]. On the other hand, they are only 39% to make use of it in Congo in this circumstance (36% of the boys and 34% of the girls). All Congolese young people present more STD (6% versus 4% for the French pupils) and more pregnancy (11% versus 3%). The other risky situations appear also more important in Congo: as the fact of having sexual intercourse after having drunk too much (6% of case where it arrives systematically versus 2% in France); to have sexual intercourse with a injecting drug user (4% versus 1%); paying or to have been paid (in a systematic way 7% versus 1%). The Congolese answers concerning the recourse to prostitution are more dissimilar and alarming concerning Congolese young people, especially if one takes into account all the situations where it occurred at least once (29% of the boys and 13% of the Congolese girls who declare to have had a sexual intercourse by paying (with money). Homosexual relations are more frequent in Congo (4 and 6% versus 2 and 3% for France). Homosexual experience concerned 13% of the Congolese pupils versus less than 5% of the French ones. The answers concerning a sexual partner who is "not sure" (20% in Congo versus 2% in France) can get clearer in the Congolese context with an elevated prevalence rate of infection by HIV. However, other cultural factors should not be neglected. The same applies for the answers relative to the sexual intercourse under duress (29% for Congo versus less than 7% in France). The answers relative to the fact of having a sexual intercourse with a much older partner (21% versus 13%) do not seem surprising for Congo. But it does not free risks. All these elements are not associated with a better estimate of the personal risk. (ABSTRACT TRUNCATED)

A study of sexual behavior among rural residents of China.

OBJECTIVE: Although the recent spread of HIV/AIDS and other sexually transmitted diseases (STDs) in China has been associated with sexual activities, little information has been available about sexual behavior in rural areas with high HIV prevalence. Studies identifying high-risk sexual behaviors are needed to formulate effective prevention programs. METHODS: A cross-sectional study design was used to measure sexual activities using a two-stage cluster sampling method. A two-part anonymous questionnaire was used. Sensitive questions related to sexual behavior were administered using a tape recorder, earphones, and an answer sheet which did not include the text. RESULTS: In total, 1057 subjects were interviewed. Among 886 sexually active individuals, 7.8% had >1 sexual partner, 22.8% had premarital sex, 2.4% had anal intercourse, 4.1% had oral intercourse, and 2.3% had both anal and oral intercourse. Less than 2% reported past or current sexually transmitted diseases. Overall, 10.4% used condoms; only 11.2% for every sexual act. History of premarital and extramarital sex was higher in younger people. CONCLUSIONS: Sexual norms in rural China are changing rapidly and high-risk sexual behavior among young rural residents is increasing. Strategies to prevent HIV/AIDS should include education to promote delayed onset of sexual activity, safer sexual behavior, and condom use.

Influences on adolescents' decision to postpone onset of sexual intercourse: a survival analysis of virginity among youths aged 13 to 18 years.

BACKGROUND: Previous research has focused on risk factors associated with early onset of sexual intercourse among adolescents. This study hypothesizes that protective factors identified for other health compromising behaviors are also protective against early onset of sexual intercourse. The study sample included 26,023 students in grades 7-12 (87.5% white, 52.5% male) who did not report a history of sexual abuse in a statewide survey of adolescent health in 1988. METHODS: Bivariate analyses were stratified into early (13-14 years), middle (15-16 years) and late (17-18 years) adolescence and by gender. Cox proportional hazards survival analysis, stratified by gender, was used to determine risk and protective factors associated with delayed onset of sexual intercourse. RESULTS: Variables showing a significant bivariate association with lower levels of sexual activity across all age groups and genders were: dual-parent families, higher socioeconomic status (SES), better school performance, greater religiosity, absence of suicidal thoughts, feeling adults or parents cared, and high parental expectations. High levels of body pride were associated with higher levels of sexual activity for all age and gender groups. In the multivariate survival analyses, variables significantly associated with delayed onset of sexual activity for both males and females included: dual-parent families, higher SES, residing in rural areas, higher school performance, concerns about the community, and higher religiosity. High parental expectations were a significant protective factor for males but not for females. CONCLUSION: While many protective factors are not subject to intervention, the present analyses indicate that teen pregnancy prevention may be enhanced by addressing family and educational factors.

Results of a model AIDS prevention program for high school students in the Philippines.

OBJECTIVES: To describe the sexual practices of high school students; to describe the process of development of a school-based AIDS prevention program; and to evaluate the effect of this program on students' AIDS-related knowledge, attitudes and AIDS-preventive behaviors. SUBJECTS AND METHODS: A cluster-randomized, controlled trial with pretest/post-test evaluation was conducted in four demographically similar public high schools in a semi-urban district of Metro Manila, the Philippines. Of 845 high school students who participated in the baseline survey, 804 (95%) completed a postintervention questionnaire. INTERVENTION: An AIDS prevention program was developed by public high school teachers together with local AIDS experts, social scientists and health educators. The teacher-led AIDS program was designed to provide students with accurate information about AIDS, particularly in dispelling misconceptions about casual contagion, to foster positive attitudes towards people with AIDS and to develop skills aimed at clarifying values and assessing intended behavior. RESULTS: At baseline, 11% of students (20% of males and 4% of females) reported ever having had sexual intercourse (mean age 14 years). Among these, condom use was low (24%). After implementation of the AIDS prevention program, statistically significant effects favoring the intervention group were observed in knowledge and attitudes towards people with AIDS. While there was no statistically significant overall effect on intended preventive behavior, the program appeared to delay the students' intended onset of sexual activity. CONCLUSIONS: A sizable number of Filipino high school students are sexually active but condom use is low. School-based AIDS prevention programs can be developed and implemented in developing countries with the assistance of school personnel to address sexual issues. Our program was successful in increasing AIDS-related knowledge and improving attitudes towards people with AIDS. Supplementation with other preventive activities may be needed to achieve lasting changes in students' risk-taking behavior.

Sexual partner change and condom use among urban factory workers in northwest Tanzania.

OBJECTIVE: To describe sexual partner change and condom use at the intake of a cohort study of urban factory workers in Tanzania. METHODS: From October 1991 to March 1992, 926 male and 170 female factory workers were interviewed using a structured, pre-coded questionnaire. Questionnaire reliability was assessed by pre-testing and comparison with results of unstructured interviews and carrying out repeat questionnaires on a sub-sample. RESULTS: Almost half of both men and women had had sexual intercourse by their 17th birthday. The period of premarital sex had an interquartile range of 2 to 10 years in men and 0 to 2.5 years in women. Having had sexual intercourse in the past month with more than one partner was reported by 22% of the men and 5% of the women. Factors associated with multiple partners in men were being born in or near Mwanza Region, having low education and low income, and being married. Condoms had been used in the past month by 3% only, mainly with casual partners. Condom use in men was associated with being young, living in town, being born in Kagera Region, high education and high income, being circumcised, and having causal or steady (non- martial) partners. CONCLUSION: Information, education and communication (IEC) on sexual relationships and condom use should start at an early age, and include education at primary schools. Much sexual partner change appears to occur through steady (non-marital) partnerships, indicating the need for IEC to be expanded beyond groups such as commercial sex workers and their clients.

Time course of effects of testosterone administration on sexual arousal in women.

BACKGROUND: The assumption that testosterone is involved in human female sexual functioning is mainly based on results of studies of women with hypogonadotropic hypogonadism. This study sought to determine the effect of testosterone administration on physiological and subjective sexual arousal in sexually functional women. METHODS: In a double-masked, randomly assigned, placebo-controlled crossover design, we examined whether administration of a single dose of testosterone to sexually functional women increases vaginal and subjective sexual arousal when they are exposed to erotic visual stimuli. To search for a time lag in the effect of testosterone therapy, we exposed 8 healthy women to 6 erotic film excerpts depicting intercourse. The first and second excerpts were shown immediately before and 15 minutes after, respectively, intake of placebo or testosterone; the last 4 excerpts were then shown at 1(1/2)-hour intervals. RESULTS: Sublingual intake of testosterone caused a sharp increase in plasma testosterone levels within 15 minutes; these levels declined to baseline values within 90 minutes. Three to 4(1/2) hours after reaching peak testosterone level, we found a statistically significantly increase in genital responsiveness (P = .04). Furthermore, on the day of testosterone treatment, there also was a strong and statistically significant association between the increase in genital arousal and subjective reports of "genital sensations" (P = .02) and "sexual lust" (P = .01) after 4(1/2) hours. CONCLUSIONS: There is a time lag in the effect of sublingually administered testosterone on genital arousal in women. In addition, a consecutive increase in vaginal arousal might cause higher genital sensations and sexual lust.

Prevalence of Kaposi's sarcoma-associated herpesvirus infection in sex workers and women from the general population in Spain.

Transmission routes of Kaposi's sarcoma-associated herpesvirus (KSHV) in the general population are poorly understood. Whereas sexual transmission appears to be common in homosexual men, the evidence for heterosexual transmission is less convincing. In our study, prevalence of KSHV infection was examined among women in the Spanish general population and among sex workers. Subjects consisted of 100 prostitutes and 100 women randomly sampled from the general population and age-matched to the prostitutes. Women had a personal interview and gynecologic examinations in which a blood sample, cervical cells and oral cells were obtained. Peripheral blood mononuclear cells (PBMC), oral and cervical samples were tested for KSHV DNA by quantitative real-time PCR. Sera were tested for antibodies against human immunodeficiency virus (HIV) by ELISA and against KSHV by latent IFA and K8.1 ELISA. Women who were positive in either serologic assay or PCR were considered infected by KSHV. Human papillomavirus (HPV) DNA in cervical scrapes were evaluated using the Hybrid Capture System. The study population had an average age of 30 years and were HIV-negative. Women from the general population were largely of Spanish nationality, and 61% reported lifetime monogamy. The majority of the prostitutes (76%) were immigrants, primarily from South America. Sex workers were twice as likely to be infected with KSHV than women in the general population (16% vs. 8%, prevalence odds ratio [OR] = 2.2). KSHV was more prevalent among HPV DNA-positive women (OR = 2.5) and among women with an early age at first sexual intercourse (OR = 2.7, p < 0.05). KSHV DNA was detected by PCR in 3% of the oral cavity samples, in 2% of the cervical samples of the prostitutes and in 1% of the cervical samples of women in the general population. All PBMC samples were negative. These results suggest that in low-risk countries for KSHV, oral shedding and heterosexual contacts are potential pathways for KSHV transmission.

Prevalence of cervical dysplasia and HPV infection according to sexual behavior.

A total of 165 uterine cervix smears from Venezuelan women were examined by cytological techniques to identify malignant and pre-malignant cervical changes, as well as to identify Human Papilloma Virus (HPV) DNA types 6, 11, 16, 18, 31, 33 and 35. Of these smears, 119 were from nonmonogamous women who participated in a cervical carcinoma screening program. In this group, HPV-DNA was detected by hybridization in 42 samples (35%) and cervical intraepithelial neoplasia (CIN) in 13 (11%). Forty-six monogamous aboriginal women were similarly studied and no evidence of abnormal cytology or HPV-DNA of the types studied here was found in any of them. In the non-monogamous group, age at first sexual intercourse and index of parity were not associated with cervical HPV infection and/or CIN. The rates of HPV infection, however, were significantly different between the two populations, confirming that sexual behavior involving multiple partners is associated with HPV infection.

Cytomegalovirus recurrence in seropositive pregnant women attending obstetric clinics.

To understand reasons for cytomegalovirus (CMV) recurrence, a cohort of 350 CMV-seropositive pregnant women attending obstetric clinics in Taiwan was examined for cervical or urinary CMV shedding. Urine specimens were collected from 350 women and cervical secretion specimens were collected from 220 women. We measured the association of various factors with CMV recurrence, which was defined as viral shedding identified by the presence of a CMV-specific gene sequence amplified by the polymerase chain reaction in seropositive individuals. CMV recurrence status was independently associated with a sexual activity composite variable, which was defined by three sexual activity indicators: age at first sexual intercourse, total years of sexual experience, and average frequency of sexual intercourse prior to pregnancy. Pregnant women with a history of genital tract infection were more likely than women without such history to experience cervical CMV recurrence. Similarly, pregnant women with previous urinary tract infections were more likely to experience urinary CMV recurrence. The findings indicate that multiple exposure to CMV by sexual activity prior to pregnancy is an important determinant of CMV recurrence during pregnancy.

Reproductive factors in the etiology of hepatocellular carcinoma. The WHO Collaborative Study of Neoplasia and Steroid Contraceptives.

Data from a hospital-based case-control study conducted in four developing countries were analyzed to evaluate the role of reproductive factors in the etiology of liver cancer. Eighty-three patients newly diagnosed with primary liver cancer and 596 matched controls between the ages of 15 and 56 years completed study interviews. The relative risk of hepatocellular carcinoma was elevated significantly in women of high gravidity, an association that was attributable to the effects of full-term pregnancies. The adjusted relative-risk estimate in women who had ever had a full-term pregnancy was 1.6 (95 percent confidence interval = 0.6-4.1), and risk increased directly with the number of full-term pregnancies (P for trend = 0.03), rising to 3.8 among women with seven or more births compared to women with one to two births. Induced abortions and a history of miscarriage were unrelated to risk. These findings were unchanged after adjustment for a history of jaundice, lifetime number of sexual partners, or age at first sexual intercourse--variables which may be related to hepatitis B virus (HBV) exposure. Serum samples to determine HBV status were not collected, however, and it is not known whether the observed associations are independent of prior HBV infection.

[Sexual behavior of Italian youths in connection to AIDS risk].

The objective of this survey is to evaluate knowledge and sexual behaviour among young Italians (19 to 24 years). The project, began in 1993, is being carried out through an anonymous postal questionnaire, sent to a representative sample of the young Italian population (a total of 52,000 people from 363 Italian towns). In the present intermediate evaluation, we have analysed 6929 of the 18,132 questionnaires sent till now, with all Italian regions being proportionally included. Our data show that, after sexual activity has been started, it hardly seems to be limited to monogamy or to be always regulated by AIDS-preventing practices. Data show that the age of the first sexual intercourse is increasing (after age 18) and that condoms are used more frequently, particularly in occasional sex.
