This study evaluates associations between unrecognized HIV infection and demographic factors, internalized homonegativity, drug use, and sexual behaviors among HIV positive men who have sex with men (MSM). We analyzed data from 347 HIV positive participants from the Los Angeles site for NIDA's Sexual Acquisition and Transmission of HIV-Cooperative Agreement Program. Participants were HIV positive MSM and MSM/W and predominantly African American (36.0%) or Latino (38.7%), and unemployed (82.8%). Results from a multivariate logistic regression suggest that, compared to HIV positive participants who correctly reported their HIV positive status, being African-American (OR: 9.81, CI: 1.2-77.9) or Latino (OR: 10.92, CI: 1.3-88.4) rather than White, MSM/W rather than MSM (OR: 3.24, CI: 1.09-9.62), and having higher homonegativity scores (OR: 1.22, CI: 1.02-1.4) is associated with unrecognized HIV infection, controlling for age, education, and homelessness. Findings provide some immediate evidence to help craft HIV prevention interventions.

This study evaluates associations between internalized homonegativity and demographic factors, drug use behaviors, sexual risk behaviors, and HIV status among men who have sex with men (MSM) and with men and women (MSM/W). Participants were recruited in Los Angeles County using respondent-driven sampling (RDS) and completed the Internalized Homonegativity Inventory (IHNI) and questionnaires on demographic and behavioral factors. Biological samples were tested for HIV and for recent cocaine, methamphetamine, and heroin use. The 722 MSM and MSM/W participants were predominantly African American (44%) and Hispanic (28%), unemployed (82%), homeless (50%), and HIV positive (48%) who used drugs in the past 6 months (79.5%). Total and Personal Homonegativity, Gay Affirmation, and Morality of Homosexuality IHNI scores were significantly higher for African American men than for other ethnicities, for MSM/W than for MSM, for recent cocaine users than for recent methamphetamine users, and for HIV-seronegative men than for HIV-seropositive men. Linear regression showed the Gay Affirmation scale significantly and inversely correlated with the number of sexual partners when controlling for effects of ethnicity/race and sexual identification, particularly for men who self-identified as straight. Highest IHNI scores were observed in a small group of MSM/W (n = 62) who never tested for HIV. Of these, 26% tested HIV positive. Findings describe ways in which internalized homophobia is a barrier to HIV testing and associated HIV infection and signal distinctions among participants in this sample that can inform targeted HIV prevention efforts aimed at increasing HIV testing.

Background: Screening for low bone mineral density (BMD) by dual-energy x-ray absorptiometry (DXA) is the primary way to identify asymptomatic men who might benefit from osteoporosis treatment. Identifying men at risk for low BMD and fracture can help clinicians determine which men should be tested. Purpose: To identify which asymptomatic men should receive DXA BMD testing, this systematic review evaluates 1) risk factors for osteoporotic fracture in men that may be mediated through low BMD and 2) the performance of non-DXA tests in identifying men with low BMD. Data Sources: Studies identified through the MEDLINE database (1990 to July 2007). Study Selection: Articles that assessed risk factors for osteoporotic fracture in men or evaluated a non-DXA screening test against a gold standard of DXA. Data Extraction: Researchers performed independent dual abstractions for each article, determined performance characteristics of screening tests, and assessed the quality of included articles. Data Synthesis: A published meta-analysis of 167 studies evaluating risk factors for low BMD-related fracture in men and women found high-risk factors to be increased age (>70 years), low body weight (body mass index <20 to 25 kg/m²), weight loss (>10%), physical inactivity, prolonged corticosteroid use, and previous osteoporotic fracture. An additional 102 studies assessing 15 other proposed risk factors were reviewed; most had insufficient evidence in men to draw conclusions. Twenty diagnostic study articles were reviewed. At a T-score threshold of -1.0, calcaneal ultrasonography had a sensitivity of 75% and specificity of 66% for identifying DXA-determined osteoporosis (DXA T-score, -2.5). At a risk score threshold of -1, the Osteoporosis Self-Assessment Screening Tool had a sensitivity of 81% and specificity of 68% to identify DXA-determined osteoporosis. Limitation: Data on other screening tests, including radiography, and bone geometry variables, were sparse. Conclusion: Key risk factors for low BMD-mediated fracture include increased age, low body weight, weight loss, physical inactivity, prolonged corticosteroid use, previous osteoporotic fracture, and androgen deprivation therapy. Non-DXA tests either are too insensitive or have insufficient data to reach conclusions. [ABSTRACT FROM AUTHOR]
