Moving from apprehension to action: HIV counseling and testing preferences in three at-risk populations.
This study sought to identify factors influencing HIV testing decisions among clients at a sexually transmitted disease clinic, gay men, and injection drug users. Focus group and intensive interview data were collected from 100 individuals. The AIDS Risk Reduction Model was adapted to describe factors that affect test decisions. Testing barriers and facilitators were grouped as factors affected by "Individual" beliefs, "System" policies and programs, "Testing" technology, and "Counseling" options. Individual factors (fear of death and change), system factors (anonymous test availability, convenience), and counseling and testing factors (rapid results, counseling alternatives) interact to determine whether an individual does not test ("apprehension") or does test ("action"), and ultimately, tests routinely ("integration"). In conclusion, traditional HIV testing presents barriers to some populations at risk for HIV. These findings suggest several strategies to improve HIV test acceptance: acknowledge fears, address system barriers, utilize available test technologies, and expand counseling options.

Developing, implementing, and evaluating a condom promotion program targeting sexually active adolescents.
This article describes the development, implementation, and evaluation of the Condom Campaign, a 1995 HIV prevention program promoting condom use among sexually active adolescents in three King County, Washington, urban communities. This program employed three main strategies: (a) mobilizing all levels of the target communities to support and guide program development and implementation; (b) creating and implementing a mass media campaign targeting sexually active teenagers that promoted correct condom use and favorable attitudes toward condoms; and (c) recruiting public agencies, community organizations, and businesses to distribute condoms from bins and vending machines. We evaluated the program through a series of cross-sectional interviews conducted in the three communities chosen for their elevated levels of adolescent sexual risk behavior. Overall, 73% of target youth reported exposure to the Condom Campaign; exposure did not differ by age, gender, race, or level of sexual experience. Levels of sexual activity remained stable throughout the media campaign.

Risk of anal carcinoma in situ in relation to human papillomavirus type 16 variants.
Infection with human papillomavirus (HPV), especially HPV16, is central to the development of squamous anogenital cancers and their precursor lesions, termed "squamous intraepithelial neoplasias." Men who have sex with men, particularly those who are infected with HIV, are at a high risk for anal infection with HPV16 and for low-grade anal neoplasia; however, only a subset of these men develop anal invasive cancer or its immediate precursor lesion, anal carcinoma in situ (CIS). To examine the hypothesis that certain variants of HPV16 are most strongly associated with development of anal CIS, we followed 589 men who have sex with men whose initial anal cytological smears did not show anal CIS. Anoscopy, anal cytology, and PCR-based assays for detection and classification of HPV types were performed every 4-6 months, with HPV16 further classified by single-stranded conformation polymorphism analysis as being a prototype-like (PL) or non-prototype-like (NPL) variant. Anal CIS was histologically confirmed in 6 of 384 (1.6%) consistently HPV16-negative men, in 12 of 183 (6.6%) men with HPV16 PL variants, and in 4 of 22 (18.2%) men with HPV16 NPL variants. After adjustment for anal cytological diagnoses at study entry, HIV status and CD4 count, and detection of HPV types other than type 16, men with HPV16 NPL variants were 3.2 times (95% confidence interval, 1.0-10.3) more likely to develop anal CIS than were those with PL variants. Neither detection of HPV16 DNA at high levels nor detection of HPV16 DNA for a prolonged period, factors that we previously demonstrated to be associated with risk of high-grade anal squamous intraepithelial neoplasia, was significantly associated with HPV16 NPL variants. The biological mechanism relating to Ihis excess risk remains undetermined.

Determinants of human immunodeficiency virus DNA and RNA shedding in the anal-rectal canal of homosexual men.
To define the determinants of anal-rectal shedding of human immunodeficiency virus (HIV) DNA and RNA, 374 HIV-seropositive homosexual men were tested. Factors independently associated with detection of anal-rectal HIV DNA included anal-rectal inflammation and detection of anal human papillomavirus DNA; predictors of HIV RNA included detection of anal-rectal HIV DNA, anal-rectal inflammation, and high plasma HIV RNA levels. The latter (>10,000 copies/mL) was the main determinant of anal-rectal HIV RNA shedding when HIV DNA (e.g., HIV-infected cells) was not detected in the anal-rectal sample. The local presence of HIV-infected cells and local inflammation were the principal determinants of HIV RNA among those with low (<10,000 copies/mL) plasma HIV RNA load. Among those with anal-rectal HIV DNA present, increased HIV RNA plasma load did not increase the risk of shedding of HIV RNA into the anal-rectal canal.

Using formative research to lay the foundation for community level HIV prevention efforts: an example from the AIDS Community Demonstration Projects.
The AIDS Community Demonstration Projects provided community-level HIV prevention interventions to historically hard-to-reach groups at high risk for HIV infection. The projects operated under a common research protocol which encompassed formative research, intervention delivery, process evaluation, and outcome evaluation. A formative research process specifically focusing on intervention development was devised to assist project staff in identifying, prioritizing, accessing, and understanding the intervention target groups. This process was central to the creation of interventions that were acceptable and unique to the target populations. Intended to be rapid, the process took 6 months to complete. Drawn from the disciplines of anthropology, community psychology, sociology, and public health, the formative research process followed distinct steps which included (a) defining the populations at high-risk for HIV; (b) gathering information about these populations through interviews with persons who were outside of, but who had contact with, the target groups (such as staff from the health department and alcohol and drug treatment facilities, as well as persons who interacted in an informal manner with the target groups, such as clerks in neighborhood grocery stores and bartenders); (c) interviewing people with access to the target populations (gatekeepers), and conducting observations in areas where these high-risk groups were reported to gather (from previous interviews); (d) interviewing members of these groups at high risk for HIV infection or transmission; and (e) systematically integrating information throughout the process. Semistructured interview schedules were used for all data collection in this process. This standardized systematic method yielded valuable information about the focal groups in each demonstration project site. The method, if adopted by others, would assist community intervention specialists in developing interventions that are culturally appropriate and meaningful to their respective target populations.

Non-gay-identifying men who have sex with men: formative research results from Seattle, Washington.
Non-gay-identifying men who have sex with men are at risk for human immunodeficiency virus (HIV) infection. To understand these men and to develop interventions to reduce their HIV risks, the authors interviewed staff at agencies that serve non-gay-identifying men who have sex with men, business people who interact with them, and the men themselves. Interviews were augmented with focus groups of non-gay-identifying men who have sex with men and field observations at sites identified as places where they meet to negotiate or have sex. These qualitative data suggested 73 possible groups, which were consolidated into 16 broader "sectors," and then formally ranked by level of HIV risk, ease of access to the sector, psychosocial risks, and influence of other local interventions or research activities. The authors identified six priority groups of non-gay-identifying men who have sex with men (and sites where members of these groups could be approached): hustlers, closeted men, experimenters, incarcerated or formerly incarcerated men, men of color, and heterosexually identified bisexuals. Masturbation and oral sex were reportedly common, but anal and vaginal sex were also noted; condom use was rarely reported. Risk behaviors among non-gay-identifying men who have sex with men persist for a variety of reasons and may require a variety of intervention approaches.

High grade anal dysplasia in visually normal mucosa in homosexual men: seven cases.
BACKGROUND: Anal cancer and anal human Papillomavirus (HPV) infection are increased in homosexual men. METHODS: We screened high risk homosexual men as part of a longitudinal study examining the effect of HIV infection on the risk of development of high grade anal intraepithelial neoplasia (AIN II, III). RESULTS: We found seven men who had histological evidence of AIN II-III with visually normal findings by anoscopy. Two men were HIV-seronegative, five were HIV-seropositive, and only one of the HIV-seropositive men had a low CD4 count < 200. Abnormal cytological results seen over follow-up periods of 3 months to 2.5 yr suggest the persistence of visually inapparent anal abnormalities. Two of the men had had small internal warts at earlier examinations, and three of the seven men subsequently developed visually abnormal anal findings. All men had HPV 16 DNA detected at some point. CONCLUSIONS: We hypothesize that high grade anal neoplasia may develop deep in the glands and can be detected by cytology before visible lesions are detected even with the aid of a colposcope. However, the implications of finding high grade anal cytology are not known at this time. Natural history studies are ongoing.

HIV transmission: Women's risk from bisexual men.
The purpose of this study was to characterize the risk of human immunodeficiency virus (HIV) infection for men who have sex with men and to identify the risk such men pose to their female sex partners. The subjects were 5480 men who were tested for HIV between January 1987 and December 1991 and who reported having had sex with a man since 1977. Men who identified themselves as bisexual or straight were more likely to use injection drugs, had a substantial HIV seroprevalence, and reported many more female partners than men who identified themselves as gay. Men who identify themselves as bisexual pose the greatest risk to their female partners.

Men's disclosure of HIV test results to male primary sex partners.
We evaluated disclosure of human immunodeficiency virus (HIV) antibody status to a main sex partner and the impact on the relationship in men who have sex with men and who are enrolled in the Acquired Immunodeficiency Syndrome (AIDS) Community Demonstration Projects cohorts. Eighty-nine percent of both seronegative and seropositive men disclosed the results to their main sex partner. Seventy percent of the seronegative men and 82% of the seropositive men who did so reported that the relationship remained "as strong as ever" after 6 months. Most men who did not disclose their test results to their main partner reported being "single" after 6 months.

Risk factors for gastroschisis.
The prevalence at birth of gastroschisis, a rare abnormality of the abdominal wall, appears to have increased over the past decade. To characterize risk factors that might explain this increase, birth certificates for Washington State residents were compared for 62 infants born with gastroschisis during the years 1984 to 1987 and 617 randomly selected unaffected infants matched for birth year. After simultaneously adjusting for 14 potential risk factors, 4 factors stood out. Infants born during January, February, or March were at greater risk than infants born in any other months (odds ratio 2.2, 95% confidence interval 1.1, 4.1). Mothers less than 25 years old were at greater risk than mothers 25 years and older, with the highest risk to mothers less than 20 years old (odds ratio 4.1, 95% confidence interval 1.4, 12.0). Women who smoked during pregnancy were at greater risk than women who did not smoke (odds ratio 2.0, 95% confidence interval 1.03, 3.8). Finally, mothers receiving inadequate prenatal care were at greater risk than mothers receiving adequate prenatal care (odds ratio 2.1, 95% confidence interval 0.99, 4.6). Unidentified behavioral and environmental exposures may explain the associations with month of birth, maternal age, and prenatal care. However, smoking during pregnancy is a plausible risk factor that should be examined further as an explanation of the apparently increasing prevalence at birth of gastroschisis in developed nations.
