Past and current STDs in a Thai adolescent population.

The study of premarital sexual intercourse in 350 Thai students aged 18-20 years in commercial schools showed that 151 subjects (43.1%) having premarital sexual intercourse--50.3 per cent never used condoms, 25.8 per cent used sometimes and 23.8 per cent used everytime. Their sexual partners were girl friends in 78.1 per cent and sex workers in 18.5 per cent. The average age of first sexual intercourse was 16.6 years. There were 87 subjects who had symptoms similar to sexually transmitted diseases. Single void-urine was tested for past and present C. trachomatis infection. There were 8 of 350 subjects (2.3%) with positive results for the leukocyte esterase activity in urine samples but only 2 cases (0.6%) were positive for C. trachomatis antigen and antibody. Detection of C. trachomatis DNA was negative in all urine samples. The antibody detection in urine samples was 11.1 per cent and in blood samples 22 per cent. There was no correlation with r = 0.3 of optical density values between urine and blood samples.

Have the AIDS campaigns changed the pattern of contraceptive usage among adolescents?

In 1984--just before the extensive public information about prevention of HIV infection by the use of the condom (the AIDS campaigns)--personal interviews about sexual experiences and use of contraception were obtained in random samples of 16-20 year old Danes. The investigation was repeated in 1989 addressing the issue of whether the behavior of adolescents regarding sexual intercourse and use of contraception has changed. In 1984 in all 286 females (respondent rate = 75.3%) and 336 males (respondent rate = 77.8%) agreed to be interviewed. The second investigation in 1989 involved new cohorts of 16-20 year olds and here 359 females (respondent rate = 77.9%) and 400 males (respondent rate = 76.3%) participated. In 1984 approximately 20% and in 1989 approximately 10% reported no use of contraception at first sexual intercourse. In both investigations oral contraception (OC) and condom were by far the predominant methods mentioned. In 1984 38.1% of females and 34.4% of males used OC and 37.2% of females and 42.1% of males employed condom. In 1989 26.7% of females and 30.8% of males used OC and 64.8% of females and 62.1% of males employed condom. No sex difference in the distribution of the various contraceptive methods could be revealed. From 1984 to 1989 the prevalence of condom increased significantly. In the first investigation 15.9% of sexually experienced females reported no present use of contraception. The most frequently used device was OC (62.7%). The second investigation collected information about contraception employed at the most recent sexual intercourse from both females and males. Approximately 5% of both sexes mentioned no use of contraception.(ABSTRACT TRUNCATED AT 250 WORDS)

Posthysterectomy intestinal prolapse after coitus and vaginal repair.

INTRODUCTION: Transvaginal bowel evisceration following either vaginal or abdominal gynecologic operations is a very rare complication. Furthermore, vaginal cuff rupture with the prolapse of the small bowel through the vagina during sexual intercourse after abdominal hysterectomy in a premenopausal woman is even more rare. However, regardless of the etiology, transvaginal evisceration requires prompt recognition and surgical intervention. CASE REPORT: Here, we report a premenopausal woman who developed transvaginal bowel evisceration during the first postoperative intercourse.

Sexual behavior in the United States 1930-1990: trends and methodological problems.

BACKGROUND AND OBJECTIVES: Arguments for population-based research on patterns of sexual behavior are reviewed, and survey data are used to illustrate the insights that can be gained from such research. STUDY DESIGN: Reports of sexual behavior obtained in surveys of large probability samples of the U.S. population are analyzed and compared to make inferences about changes in the age of onset of sexual intercourse and the patterns of heterosexual and same-gender sexual behaviors of American men and women who entered adulthood during the period from 1930 to 1990. RESULTS: Strong trends are documented for both a decline in the reported age at first heterosexual intercourse and an increase in the numbers of heterosexual partners reported during adulthood. Similar evidence on patterns of same-gender contact indicate a relatively stable prevalence of reported male-male contact for cohorts of men born from the 1930s through the 1960s. Preliminary analyses suggest, however, that there has been a substantial increase in the proportion of women reporting female-female sexual contact during adulthood. Although the analyses require refinement, it appears that the prevalence of reported female-female contact may have increased by a factor of 3 to 4 for cohorts of women born between the 1930s and the 1960s. CONCLUSIONS: Although the trends in reported behaviors are robust, inferences about behavior, pre se, rest on the assumption that reporting biases were equivalent across cohorts. Methodological challenges in the interpretation of such findings and new technologies for conducting such research are described.

[Rate of precocious sexual intercourse in adolescents in disadvantaged socioeconomic environments. (University of Quebec in Montreal)].

This article presents a preliminary study, a descriptive one, on the sexual intercourse precocity rates at adolescence. 765 male adolescents francophones, 13 years old, from low economic status answered the QAS, questionnaire on aspects of sexual life including. The results show that 11.3% of subjects are sexually active by 13 years old. The first sexual partner is known from many months to many years from the majority of subjects. The majority (61.8%) of the non-sexually active subjects of the research would be near to transit to the first sexual intercourse if we consider the results of our predictive measure of the transition. Discussed at the light of the literature, these results show that early sexual behaviors are: 1) a concrete reality for an important proportion of male adolescents from low economic status; 2) to consider in the future in terms of research priority.

Trends in sexual behaviours and infections among young people in the United States.

OBJECTIVES: To describe trends over time in sexual behaviour, condom use, and sexually transmitted infections among female and male adolescents in the United States. METHODS: A review was carried out of published studies using data from six surveys since the 1970s on sexual behaviour and surveillance data on sexually transmitted infections. RESULTS: The proportion of adolescents who have ever had sexual intercourse increased for females and males through the 1980s and then declined for males through the 1990s. Some survey data showed that the level remained unchanged in the 1990s for adolescent females and other sources showed a decline by 2001. Condom use at first sexual intercourse and current condom use have increased over the past two decades for both male and female adolescents. Incidence rates for gonorrhoea and syphilis among adolescents declined over the 1990s and up through 2002, though new diagnoses of HIV/AIDS among adolescents remained relatively constant throughout the 1990s and into the new century. CONCLUSION: Although data sources are difficult to compare over time, trends in sexual behaviour, condom use, and sexually transmitted infections among adolescents from different data sources display generally similar directions towards declines in risk behaviours and outcomes, and increases in protective behaviours.

Girls experiencing sexual intercourse early: could it play a part in reproductive health in middle adulthood?

The aim of the present study is to examine the possible relationship between experiencing early intercourse and reproductive health characteristics in midlife for women. The participants belonged to the Swedish longitudinal research program Individual Development and Adaptation (IDA) project. By the age of 14, the cohort consisted of 590 girls, whereas 522 gave information about the timing of their first sexual intercourse experience. Approximately 29 years later, when the women were 43 years old, a sub-cohort of 369 women participated in the psychological-medical investigation. Those who experienced early intercourse were likely to be different on various demographics and have markers of poorer reproductive health characteristics than their counterparts. More specifically, those experiencing early intercourse were less formally educated, left home earlier, and earned on average less than their counterparts who experienced sexual intercourse later. Early intercourse likely plays a role in not only specific reproductive health but also reproductive health characteristics as a whole in midlife. Early intercourse was consistently a predictor of teenage pregnancy, terminated pregnancies, no use of contraception, and having menstrual symptoms.

[Congenital vaginal atresia and simultaneous vesico-vaginal fistula].

OBJECTIVES: To describe an uncommon case of congenital atresia of the vagina associated with vesico-urethro-vaginal fistula caused by violent coitus. METHODS/RESULTS: We report on a patient who was unaware she had the Rokitanski-Mayer-Kuster-Hauser syndrome when she had her first sexual intercourse which caused partial destruction of the urethra and bladder neck, resulting in complete incontinence. The different surgical procedures performed to recovery urinary continence and the creation of a viable vaginal tunnel are described. CONCLUSIONS: Congenital atresia of the vagina is uncommon. To our knowledge, this is the first case with associated vesico-urethro-vaginal fistula reported in the literature.

Sexual socialization and motives for intercourse among Norwegian adolescents.

The impact of gender differences in sexual socialization on early sexual experiences among Norwegian adolescents is discussed. The material comprises a stratified sample of 920 adolescents ages 16-20 years in a Norwegian county. Data were collected by means of questionnaires. Of the respondents, 55.5% were girls and 44.5% were boys. 52.3% of girls and 41.4% of the boys had coital experience. The most common reasons for having had the first sexual intercourse were being in love, curiosity or excitement, and sexual arousal. Findings from a discriminant analysis showed that emotional reasons were more important to girls, whereas boys seemed more practical in sexual matters. More boys than girls reported that the reason for having had their most recent intercourse was that the partner wanted it. This indicates that if girls do not want sex, boys seldom use pressure. Girls set the premises for sexual interaction but are not as sexually skilled as boys.

[Sexual activity and sexually transmitted diseases in high school students in Rio Branco-Acre, Brazil].

This study was realized with 2.684 students of the high school in Rio Branco-Acre, Brazil, to verify aspects of the sexual activity and the occurrence of DST/AIDS. From the researched students, 48.9% had sexual intercourse, and the largest frequency was 34.3% for male sex, with the beginning at 13 years old, and for female sex 31.6%, with the beginning at 16 years old. The occurrence of mentioned DST/AIDS was: 58.4% for Hepatitis B, 39.4% for Monilíase and 2.2% for Gonorrhea. Among those ones who had their first sexual intercourse, 47.6% were with the boyfriend, 25.8% with the neighbor and 10.5% with the domestic maid. Concluding, the students who had sexual intercourse were 52.3% of private schools, 50.0% of federal ones, 45.7% of state ones and 41.8% of municipal ones.

Vaginal trauma at sexual intercourse in Ilorin, Nigeria. An analysis of 36 cases.

Over a six-year period (1982-1987), 36 cases of vaginal trauma at sexual intercourse managed in the gynaecological unit of the University of Ilorin Teaching Hospital are presented. The serious nature of this accident is stressed. The frequent involvement of the posterior fornix of the vagina, accounting for 50% of the cases is shown. Perforation of the pouch of Douglas with possible intestinal prolapse, and involvement of the urinary bladder resulting in vesicovaginal fistula are not common in Ilorin. The predisposing factors like rough coitus, first sexual intercourse, puerperium, surgical alteration of the vagina, peno-vaginal disproportion and multiparity are discussed. The importance of adequately preparing the women emotionally and physically for coitus, a matter which certain males tend to ignore, is emphasized. The necessity for thorough digital as well as speculum examination in all cases of vaginal bleeding is made. There was no death recorded, while the morbidity was mainly hypovolaemic shock with haemorrhagic anaemia.

Barrier methods, length of preconception intercourse, and preeclampsia.

BACKGROUND: The immune maladaptation theory suggests that tolerance to paternal antigens, resulting from prolonged exposure to sperm, protects against the development of preeclampsia. We tested whether barrier contraception and shorter sexual experience with the father of the pregnancy would increase the risk of preeclampsia. METHODS: Of 2211 women delivering singleton births after enrollment in a pregnancy cohort study, 85 (3.8%) developed preeclampsia as defined by antepartum systolic blood pressure > or = 140 or diastolic blood pressure > or = 90 plus proteinuria. At a mean of 10.2 weeks of gestation, all women in the cohort were asked about preconception contraception and timing of first sexual intercourse with the father of the pregnancy. Odds ratios (OR) comparing cases with preeclampsia to the rest of the cohort were adjusted for age, smoking, parity, and body mass index (BMI). RESULTS: Women using barrier contraception prior to conception were no more likely than women not using barrier contraception to develop preeclampsia (adjusted OR 1.0, 95% CI 0.6-1.6). In unadjusted analyses, a prolonged time to conception was associated with preeclampsia (OR 1.9), however, after adjustment, the association was less prominent (OR 1.6) and after stratification by contraception method, the link between time to conception and preeclampsia was eliminated. CONCLUSION: These data do not support the immune maladaptation theory of preeclampsia.

The jus primae noctis as a male power display. A review of historic sources with evolutionary interpretation.

The jus primae noctis was, in the European late medieval context, a widespread popular belief in an ancient privilege of the lord of the manor to share the wedding bed with his peasants' brides. Symbolic gestures, reflecting this belief, were developed by the lords and used as humiliating signs of superiority over the dependent peasants in the fifteenth century, a time of diminishing status differences. Actual intercourse in the exercise of the alleged right is difficult to prove, and there is no hard evidence to suggest that it ever actually happened. However, the symbolic gestures can be best interpreted as a male power display, with a basis in the psychology of coercive social dominance, male competition, and male desire for sexual variety. Several non-European cultures have accounts of a similar custom related to a young girl's first sexual intercourse: ritual defloration by chiefs, priests, or strangers. This non-European custom differs from the jus primae noctis in its proximate details, but seems from an ultimate point of view, to be in conformity with the European evidence. In this article the origin, development, and relationship of both customs are discussed and interpreted in light of recent evolutionary studies of primate behavior and sexual psychology.

Prevalence and determinants of genital shedding of herpes simplex virus among women attending Italian colposcopy clinics.

OBJECTIVES: To determine the prevalence of herpes simplex virus (HSV) shedding among women attending Italian colposcopy clinics and describe their lifestyle, demographic characteristics, genital symptoms and signs. STUDY DESIGN: A cross-sectional study was performed to assess shedding of HSV among 4565 women requiring a gynecological consultation. An amplified enzyme immunoassay that detects an HSV type-common glycoprotein D was used to reveal HSV shedding in cervical specimens. Statistical analysis was performed using Chi-square test and Student's t test. RESULTS: A prevalence of 7.8% was found among colposcopy clinic patients. No significant differences regarding patients' average age, age at first sexual intercourse, contraceptive method used, and number of sexual partners in the previous year were found between subjects with and without viral shedding (P > 0.05). The detection of a concomitant genital infection with Trichomonas vaginalis as well as the report of previous episodes of genital herpes (GH) were significantly higher in the positive group (P < 0.01). Only 2.8% of the patients shedding HSV presented with vesicles and ulcers, with the majority of them being asymptomatic. CONCLUSION: This is the first Italian survey on genital herpes conducted among colposcopy clinic patients. Our data show that the prevalence of HSV shedding in this study population is high and confirms that the disease is often asymptomatic. The demographics and behavioural variables of women shedding HSV seem to differ from the ones assessed in high risk patients.

[A cohort study on cancer of uterine cervix in Jingan county, Jiangxi province].

A cohort study on 24,628 married women beyond 30 years of age in Jingan county, Jiangxi province was carried out from 1974 to 1985. It was equivalent to 207,490 person-year. The results showed that the earlier the first sexual intercourse the higher the risk of cervical cancer. There was a significant linear trend. The relative risk (RR) of cervical cancer in women increased from 1.63 to 6.85 with increase in the number of sex partners from one to two or more. The risk also increased from 1.44 to 5.38 and 2.69 as their husband had one, two or three and more extramarital sex partners. Irregular menstruation and insanitary mentrual pads were also risk factors. Risk factors of menarche age, age of first delivery, number of children, smoking and drinking were balanced in the present analysis by the logistic regression model.

Change in sexual behaviour and decline in HIV infection among young pregnant women in urban Uganda.

OBJECTIVE: To describe sexual behaviour that may partly explain a decline in HIV seroprevalence in pregnant women in urban settings in Uganda, East Africa. SETTINGS: Two major urban districts in Uganda. METHODS: Repeated population-based behavioural surveys in 1989 and 1995, and repeated HIV serological surveys in consecutive pregnant women attending antenatal clinics from 1989 to 1995. RESULTS: During the study period, a 2-year delay in the onset of sexual intercourse among youths aged 15-24 years and a 9% decrease in casual sex in the past year in male youths aged 15-24 years were reported. Men and women reported a 40% and 30% increase in experience of condom use, respectively. In the same study area, over the same period, there was an overall 40% decline in the rates of HIV seroprevalence among pregnant women attending antenatal clinics. It can be hypothesized that the observed declining trends in HIV correspond to a change in sexual behaviour and condom use, especially among youths. CONCLUSIONS: This is the first report of a change over a period of 6 years in male and female sexual behaviour, assessed at the population level, that may partly explain the observed decline in HIV seroprevalence in young pregnant women in urban Uganda. This result should encourage AIDS control programmes to pursue their prevention activities.
