Test-retest reliability of self-reported sexual behavior, sexual orientation, and psychosexual milestones among gay, lesbian, and bisexual youths.

Despite the importance of reliable self-reported sexual information for research on sexuality and sexual health, research has not examined reliability of information provided by gay, lesbian, and bisexual (GLB) youths. Test-retest reliability of self-reported sexual behaviors, sexual orientation, sexual identity, and psychosexual developmental milestones was examined among an ethnically diverse sample of 64 self-identified GLB youths. Two face-to-face interviews were conducted approximately 2 weeks apart using the Sexual Risk Behavior Assessment Schedule for Homosexual Youths (SERBAS-Y-HM). Overall, the mean of the test-retest reliability coefficients was substantial for 6 of the 7 domains: lifetime sexual behaviors (M=.89), sexual behavior in the past 3 months (M=.96), unprotected sexual behavior in the past 3 months (M=.93), sexual identity (kappa=.89), sexual orientation (M=.82), and ages of various psychosexual developmental milestones (M=.77). Inconsistent reliability was found for reports of sexual behaviors while using substances. A small number of gender differences emerged, with lower reliability among female youths in the lifetime number of same-sex partners. The overall findings suggest that a wide range of self-reported sexual information can be reliably assessed among GLB youths by means of interviewer-administered questionnaires, such as the SERBAS-Y-HM.

Assessment of sexual behavior, sexual attitudes, and sexual risk in Sweden (1989-2003).

To assess changes in sexual behavior, sexual attitudes, and sexual risk related to HIV, we conducted mailed questionnaire surveys in random samples of the Swedish general population in 1989, 1994, 1997, 2000, and 2003 (total N = 13,762). Each sample consisted of 4,000-6,000 subjects aged 16-44 years, stratified by age: 16-17, 18-19, 20-24, 25-34, and 35-44 years. The overall participation rate was 63.8% (for men, 55.9%; for women, 71.9%). The prevalence of three or more sexual partners and casual sexual contacts without the use of a condom was comparatively high for men, for persons aged 16-24 years, single persons with and without a regular partner, and persons living in towns and urban areas. The prevalence of multiple sexual partners and casual sexual contacts increased significantly over time. There was a significant decrease in the proportion of participants who agreed with the statement "Sexual intercourse should only take place in a stable relationship." Personal risk assessments related to HIV did not change significantly over time. The study shows that risky sexual behavior related to HIV/AIDS increased in the Swedish population between 1989 and 2003, and that attitudes concerning casual sexual relations became more permissive.

Gender differences in sexual behaviors, sexual partnerships, and HIV among drug users in New York City.

We compared sexual behaviors/partnerships and determined sexual risk correlates associated with HIV by gender among street-recruited drug users using chi-square tests and logistic regression. Men reported higher risk sexual behaviors, yet fewer high-risk sexual partners than women. After adjustment, HIV seropositive men were more likely than seronegatives to be older, MSM, use condoms, and have an HIV-infected partner. HIV seropositive women were more likely to be older, have an HIV-infected partner, and not use non-injected heroin. IDU was not associated with HIV. Prospective studies are needed to determine how gender-specific sexual behaviors/partnerships among drug users affect HIV acquisition.

Sexual behavior, sexually transmitted diseases, and risk of cervical cancer.

To explore sexually transmitted diseases and sexual behavior as risk factors for cervical cancer, we analyzed data from a population-based case-control study of breast and cervical cancer in Costa Rica. Data from 415 cases of cervical carcinoma in situ, 149 cases of invasive cervical cancer, and 764 controls were included in the analysis. Multivariate analysis showed that lifetime number of sex partners, first intercourse before age 15 years, number of livebirths, herpes simplex virus type 2 seropositivity, and serologic evidence of previous chlamydial infection were predictors of carcinoma in situ. Serologic evidence of previous syphilis was not associated with carcinoma in situ. Predictors for invasive cervical cancer included lifetime number of sex partners, first intercourse before age 15 years, number of livebirths, serologic evidence of previous syphilis, herpes simplex type 2 infection, and chlamydial infection. Cigarette smoking, socioeconomic status, self-reported history of sexually transmitted diseases, and douching were not associated with either carcinoma in situ or invasive cervical cancer.

Sexual behavior, sexually transmitted diseases and prostatitis: the risk of prostate cancer in black men.

PURPOSE: Black men are diagnosed with prostate cancer more often than white men, present with more advanced disease and have worse stage specific survival. Given the high risk of incidence and mortality in this population, determining potentially modifiable factors is important. Recent studies have suggested a link between chronic inflammation and development of prostate cancer. In concurrence, population based studies of white men have revealed an increased risk of prostate cancer with history of sexually transmitted diseases and prostatitis. MATERIALS AND METHODS: We explored the chronic inflammation hypothesis of prostate cancer development among black men by examining sexual activity, sexually transmitted diseases and prostatitis in a population based study of 129 patients and 703 controls 40 to 79 years old. RESULTS: After adjusting for age, income, cigarette smoking, and history of digital rectal examination and prostate specific antigen tests in the last 5 years, we observed that a history of gonorrhea infection and prostatitis increased the odds of prostate cancer 1.78-fold (95% CI 1.13, 2.79) and 4.93-fold (95% CI 2.79, 8.74), respectively. Men reporting 25 or more sexual partners were 2.80 (95% CI 1.29, 6.09) times more likely to be diagnosed with cancer compared to men with 5 or fewer partners. CONCLUSIONS: Our findings support the significance of prior sexual practices, exposure to sexually transmitted microbial agents and history of prostatic infection in the natural history of prostate cancer in black men. Additional prospective research incorporating serological markers of infectious agents or predictive markers of chronic inflammation should serve to elucidate the possible causal pathway of recurring or persistent infection in the etiology of prostate cancer in black men.

Sexual behavior, sexually transmitted diseases, male circumcision and risk of HIV infection among women in Nairobi, Kenya.

OBJECTIVE: To study risk factors for HIV infection among women in Nairobi, Kenya, as the epidemic moves beyond high-risk groups. DESIGN: A cross-sectional case-control study among women attending two peri-urban family planning clinics. METHODS: A total of 4404 women were enrolled after giving written informed consent. Information on risk factors was obtained by interview using a structured questionnaire. Blood was taken for HIV and syphilis testing, and genital specimens for gonorrhea and trichomoniasis screening. RESULTS: Two hundred and sixteen women (4.9%; 95% confidence interval, 4.3-5.5) were HIV-1-positive. Although risk of HIV was significantly increased among unmarried women and among women with multiple sex partners, most seropositive women were married and reported only a single sex partner in the last year. Women with a history or current evidence of sexually transmitted disease were at significantly increased risk; however, the prevalence of these exposures was low. Women whose husband or usual sex partner was uncircumcised had a threefold increase in risk of HIV, and this risk was present in almost all strata of potential confounding factors. Only 5.2% of women reported ever having used a condom. CONCLUSIONS: These data suggest that, among women who are not in high-risk groups, risk of HIV infection is largely determined by their male partner's behavior and circumcision status. Interventions designed to change male sexual behavior are urgently needed.

Sexual behaviors, sexual orientation and gender identity in adult intersexuals: a pilot study.

PURPOSE: Sexual preference and adjustment of intersexuals have rarely been investigated. Interview techniques were used to explore these issues. MATERIALS AND METHODS: Ten adult intersexuals (average age 34.2 years) were randomly selected from Intersex Society of North America members. Of the 10 subjects 8 had initially been gender assigned as female and 2 as male. A structured telephone interview was used to assess sexual orientation, sexual activity and satisfaction with gender assignment. RESULTS: Sexual debut occurred at age 18.1 years (range 15 to 22). At debut, 4 females and 2 males engaged in heterosexual intercourse, and 4 females engaged in gynephilic (female) sexual contact. Despite female gender assignment of 8 and initial heterosexual activity by 4 subjects, the final choice of a sexual partner was female in all 8. Both males had initial heterosexual contact but only 1 continued to prefer female partners. Current number of sexual partners averaged 0.9 (range 0 to 2) and total number of sexual partners ranged from 1 to 300. Currently, 9 subjects are in a committed sexual relationship and 8 are able to achieve orgasm. Of the subjects 8 preferred being identified as intersexual, 1 male as male and 1 female as female. Two intersexuals with initial female gender assignment were undergoing male reassignment. CONCLUSIONS: Most intersexuals preferred being identified as intersexual and had female partners. Most reported being satisfied with overall physical appearance but satisfaction with genitalia was highly variable. Based on these results, further study of a larger population is warranted.

Sexual behavior, sexual swelling, and penile evolution in chimpanzees (Pan troglodytes).

Functional relationships between the penis, vagina, and cervix during copulation in the chimpanzee were studied. In 11 adult males, penile length during full erection ranged from 10.0-18.0 cm (mean +/- SD = 14.4 +/- 2.02). In 19 parous adult females examined during the early follicular phase of the cycle, or during lactation, vaginal depth (from the introitus to the os cervix) ranged from 9.8-16.5 cm (mean +/- SD = 12.6 +/- 1.69). However, when the sexual skin was maximally swollen, vaginal depth increased by up to 52% in some cases and ranged from 15.2-20.1 cm (mean +/- SD = 16.9 +/- 1.68). Under such conditions males vary in their ability to achieve maximal depth of intromission. Observations made on 6 females after natural matings revealed that in some cases males had deposited copulatory plugs in contact with the cervix, while in others plugs were lower down in the vagina. Direct observations under fluoroscopy using an artificial "penis" loaded with radio-opaque medium showed that the filiform tip can make contact with the os cervix. However, expulsion of radio-opaque medium under these conditions failed to demonstrate any immediate transfer of fluid through the cervix into the uterus. These studies indicate that, aside from its functions as a visual signal, the female chimpanzee's sexual skin swelling adds considerably to the distance males must negotiate during copulation to place spermatozoa at the cervical os. Evolution of the male's elongated, filiform penis may therefore be the result of sexual selection, to negotiate the long vagina of the female and to penetrate copulatory plugs deposited during previous copulations.

National survey of sexual behavior and sexual behavior policies in facilities for individuals with mental retardation/developmental disabilities.

To obtain information regarding sexual behavior and related policies in state residential facilities for individuals with mental retardation/developmental disabilities, we sent surveys to 168 members listed in the Association of Public Developmental Disabilities Administrators 1998-1999 directory. Response rate was 68.5%. For the 46 facilities where 50% or fewer of clients had profound retardation, sexual relations between clients was reported to occur "sometimes" or "often" by 29 (63%). Six of 115 (5.2%) administrators reported at least one client with a sexually transmitted disease (STD) in the past year. Of 110 instances of sexual abuse reported, the perpetrator was another client in 63% of cases. Ninety-six percent of administrators (n = 110) reported their facility had written guidelines concerning sexual abuse. Careful monitoring of STDs and the effectiveness of sex education will be instrumental in preventing HIV/STDs and helping prevent sexual abuse in this vulnerable population.

HIV-positive men sexually active with women: sexual behaviors and sexual risks.

This study examines patterns of sexual behavior, sexual relating, and sexual risk among HIV-positive men sexually active with women. A total of 278 HIV-positive men were interviewed every 6-12 months between 1994 and 2002 and reported considerable variability in sexual behaviors over time. Many were not sexually active at all for months at a time; many continued to have multiple female and at times male partners. Over one-third of the cohort had one or more periods when they had engaged in unprotected sex with a female partner who was HIV-negative or status unknown (unsafe sex). Periods of unsafe sex alternated with periods of safer sex. Contextual factors such as partner relations, housing status, active drug use, and recently exchanging sex showed the strongest association with increased odds of unsafe sex. A number of predictors of unsafe sex among African American men were not significant among the Latino sub-population, suggesting race/ethnic differences in factors contributing to heterosexual transmission. Implications for prevention interventions are discussed.

Androgens and sexual behavior.

Sexual behavior in humans may be classified according to gender role, gender identity, and gender orientation. Sexually dimorphic behavior in humans is generally felt to be determined by postnatal socialization. Recent work in laboratory animals shows that sexual behavior is a function of circulating steroid hormones, particularly androgens. Testosterone given during a critical period in prenatal or immediate postnatal life causes permanent organizational effects on brain structure and function in laboratory animals. Studies in human patients with testicular feminization, 5-alpha-reductase deficiency, congenital adrenal hyperplasia, or prenatal steroid hormone exposure, provide clinical examples of possible effects of prenatal hormone action in the brain as opposed to postnatal socialization. However, these studies do not permit a clear assessment of the role played by either prenatal steroid hormones or postnatal socialization factors in the ultimate expression of sexual behavior in humans.

Patient sexual behaviors and sexual harassment: a national survey of physical therapists.

BACKGROUND AND PURPOSE: The objective of this study was to describe the extent to which physical therapists have experienced patient sexual behaviors and sexual harassment. SUBJECTS AND METHODS: A questionnaire was mailed to 750 individuals selected from a computer-generated, randomized sample provided by the American Physical Therapy Association of members who identified themselves as being licensed physical therapists and currently engaged in clinical practice. Completed questionnaires were returned by 48.6% of the eligible sample. RESULTS: Eight-six percent of the respondents reported having experienced some form of patient sexual behavior in the course of practice. The vast majority of these incidents were not rated as harassment. Sixty-three percent of the respondents, however, reported at least one incident of sexual harassment. Despite those high rates, less than one third of the respondents had received any training in how to handle sexual harassment. CONCLUSION AND DISCUSSION: The results support the findings of previous investigators who concluded that patient sexual behavior and sexual harassment is an important issue that needs to addressed in training programs.

Medial preoptic area kindling induces sexual behavior in sexually inactive male rats.

In the present experiments, sexually experienced and non-copulating male rats were kindled in the medial preoptic area (MPOA) or the amygdala (AMG) with the purpose to investigate if the widespread modification of brain function produced by kindling induces sexual behavior in non-copulating rats and if kindling facilitates sexual behavior in copulating rats. Since kindling in the MPOA has been little studied, a description of this phenomenon is also presented. The animals were stimulated 4 times daily on odd days and sexual behavior monitored on even days. The results showed that the MPOA required higher stimulus intensity to elicit an afterdischarge (AD) than the AMG. The AD duration was significantly longer in animals kindled in the MPOA than in animals kindled in the AMG. No difference was found in the development of kindling between these brain structures. Kindling had no effect upon sexual behavior in copulating rats. In contrast, MPOA kindling induced copulation in non-copulating male rats. Seven out of 9 animals displayed sexual behavior. No significant facilitation was observed after AMG kindling in non-copulating male rats. Furthermore, the sexual behavior displayed by the previously non-copulating MPOA kindled rats was similar to the sexual behavior displayed by sexually experienced animals. It is proposed that sexual behavior is facilitated in these male rats by local neural changes produced by kindling.

Association of condom use, sexual behaviors, and sexually transmitted infections with the duration of genital human papillomavirus infection among adolescent women.

OBJECTIVE: To examine the association of potentially modifiable factors such as condom use, sexual behaviors, and concurrent sexually transmitted infections with duration of genital human papillomavirus (HPV) infections among adolescent women. DESIGN: Longitudinal observational study. SETTING: Study conducted at 3 inner-city clinics in Indianapolis, Ind. PARTICIPANTS: Forty-nine HPV-positive adolescents were tested frequently for HPV infection and provided sexual behavior diaries. Main Exposures Condom use, sexual behaviors, number of partners, and concurrent infections with Neisseria gonorrhoeae, Chlamydia trachomatis, and Trichomonas vaginalis. MAIN OUTCOME MEASURES: Time from onset to clearance of type-specific HPV infections was analyzed with proportional hazard models. Adjusted hazard ratios (AHRs) were used to assess the effects of risk factors on the duration of HPV infection. Because viral clearance is a preferred outcome, a variable with an AHR less than 1 was considered a risk factor (ie, associated with reduced chance of viral clearance and prolonged infection). RESULTS: Prolonged HPV infection was associated with oncogenic HPV types (AHR, 0.58 [95% confidence interval (CI), 0.39-0.84]) less than median level of condom use during an HPV infection (AHR, 0.53 [95% CI, 0.33-0.84]) and coinfection with C trachomatis (AHR, 0.58 [95% CI, 0.31-0.89]) or T vaginalis (AHR, 0.32 [95% CI, 0.16-0.64]). Not having multiple sexual partners during an HPV infection was associated with early HPV clearance (AHR, 5.52 [95% CI, 3.28-9.30]). CONCLUSIONS: These findings support public health messages of reducing the number of sexual partners, promoting routine condom use, and frequent sexually transmitted infection screening that may be beneficial with HPV infections.

Sexual behavior and sexual function of adults after hypospadias surgery: a comparative study.

PURPOSE: We assessed sexual behavior and sexual function in adults operated on for hypospadias. MATERIALS AND METHODS: Long-term psychosexual adjustment was assessed with a standardized questionnaire which was mailed to 57 patients with hypospadias older than 18 years and 60 age matched normal control subjects. RESULTS: A total of 37 patients with hypospadias and 39 controls participated. Self-reported strength of libido on a scale of 1 to 5 was shown to be similar in the 2 groups. Patients with hypospadias did not have problems in achieving erection and average self-rated quality of erection ranging from 1 to 5 was the same as that of controls (mean value 4.5). Patients with hypospadias noted curvature in a downward direction in a significantly higher proportion compared to controls (40% vs 18%, respectively). There were 13 patients with hypospadias who had ejaculation difficulties, of whom 6 had spraying and 7 had only dribbling of ejaculate. Patients with hypospadias masturbated significantly less often, were significantly less sexually active and had a smaller total number of sexual partners compared to control subjects. Control subjects were significantly more completely satisfied with their sexual life compared to patients with hypospadias (76.92% vs 51.35%, respectively). CONCLUSIONS: Sexual function of patients who underwent surgery for hypospadias in general is not affected. However, there is clearly a difference in certain aspects of sexual behavior between patients with hypospadias and controls. Followup and adequate counselling of patients who underwent surgery for hypospadias in adult life is necessary.

Concordance between sexual behavior and sexual identity in street outreach samples of four racial/ethnic groups.

BACKGROUND: There is a discrepancy between self-reported sexual identity and sexual behavior. The magnitude of this discrepancy is unclear, as is its variation across race/ethnicity and gender. GOAL: The goal of the study was to assess the range of discrepancy in self-reported sexual identity and sexual behavior in men and women of four racial/ethnic groups. STUDY DESIGN: Self-reported data on sexual identity (homosexual, bisexual, heterosexual) and sexual behavior in the past 3 months were collected from 1494 African American, Hispanic, Asian, and white men and women in public congregation places in Houston, Texas. RESULTS: Data indicated that concordance rates between self-reported sexual identity and sexual behavior varied widely across racial/ethnic groups, with the highest rates of concordance in Asian males and females and the lowest in African American females and white males. The largest discordant category was in those self-described heterosexuals who reported partners of both genders. Breakdown of data to exclude those who reported sex trade work or illegal sources of income improved the concordance rates for African American and Hispanic subsamples. CONCLUSION: Data indicate the importance of designing and targeting HIV risk interventions and clinical screening, based on behavior and not reported sexual identity.

Subjective and objective measures of attractiveness and their relation to sexual behavior and sexual attitudes in university students.

This study examined both self-rated and objectively measured attractiveness in relation to sexual behaviors and attitudes in an undergraduate sample (N=456). About a quarter of the variance in self-ratings of attractiveness was predicted from combining standard objective measures of attractiveness, including face photo ratings, body mass index, and chest-to-waist ratio for men, and face photo ratings, body mass index, and waist-to-hip ratio for women. Correlations were investigated among self-rated attractiveness, measured attractiveness, the residual component of self-rated attractiveness (controlling for measured attractiveness), and a number of sexual and related variables. Measured attractiveness correlated moderately with sexual behaviors but not with sociosexuality or sexual moral attitudes, indicating that higher levels of observable attractiveness may serve to increase opportunities for sex with multiple desirable partners without affecting interests in or moral acceptance of casual sex. Self-rated attractiveness correlated positively with sexual behaviors and with sociosexuality, but the correlation with sociosexuality was based entirely on residual factors beyond the objective measures of attractiveness. Other predictors of sexual behavior were discussed in terms of their variable roles in affecting interest in, opportunities for, and social costs of promiscuous sexual activity.
