Article: The relationship between community structural characteristics, the context of crack use, and HIV risk behaviors in San Salvador, El Salvador.
[show abstract] [hide abstract]
ABSTRACT: This paper explores community structural factors in different low-income communities in the San Salvador, El Salvador, that account for differences in the social context in which crack is used and HIV risk behaviors among crack users. Results suggest that both more distal (type of low-income community, level of violent crime, and poverty) and proximate structural factors (type of site where drugs are used, and whether drugs are used within or outside of community of residence) influence HIV risk behaviors among drug users. Additionally, our results suggest that community structural factors influence the historical and geographic variation in drug use sites.Substance Use & Misuse 02/2012; 47(3):265-77. · 1.10 Impact Factor -
Article: Access to housing subsidies, housing status, drug use and HIV risk among low-income U.S. urban residents.
[show abstract] [hide abstract]
ABSTRACT: Much research has shown an association between homelessness and unstable housing and HIV risk but most has relied on relatively narrow definitions of housing status that preclude a deeper understanding of this relationship. Fewer studies have examined access to housing subsidies and supportive housing programs among low-income populations with different personal characteristics. This paper explores personal characteristics associated with access to housing subsidies and supportive housing, the relationship between personal characteristics and housing status, and the relationship between housing status and sexual risk behaviors among low-income urban residents. Surveys were conducted with 392 low-income residents from Hartford and East Harford, Connecticut through a targeted sampling plan. We measured personal characteristics (income, education, use of crack, heroin, or cocaine in the last 6 months, receipt of welfare benefits, mental illness diagnosis, arrest, criminal conviction, longest prison term served, and self-reported HIV diagnosis); access to housing subsidies or supportive housing programs; current housing status; and sexual risk behaviors. To answer the aims above, we performed univariate analyses using Chi-square or 2-sided ANOVA's. Those with significance levels above (0.10) were included in multivariate analyses. We performed 2 separate multiple regressions to determine the effects of personal characteristics on access to housing subsidies and access to supportive housing respectively. We used multinomial main effects logistic regression to determine the effects of housing status on sexual risk behavior. Being HIV positive or having a mental illness predicted access to housing subsidies and supportive housing, while having a criminal conviction was not related to access to either housing subsidies or supportive housing. Drug use was associated with poorer housing statuses such as living on the street or in a shelter, or temporarily doubling up with friends, acquaintances or sex partners. Living with friends, acquaintances or sex partners was associated with greater sexual risk than those living on the street or in other stable housing situations. Results suggest that providing low-income and supportive housing may be an effective structural HIV prevention intervention, but that the availability and accessibility of these programs must be increased.Substance Abuse Treatment Prevention and Policy 11/2011; 6:31. · 1.16 Impact Factor -
Article: Influence of coping, social support, and depression on subjective health status among HIV-positive adults with different sexual identities.
[show abstract] [hide abstract]
ABSTRACT: The authors examined associations between psychosocial variables (coping self-efficacy, social support, and cognitive depression) and subjective health status among a large national sample (N = 3,670) of human immunodeficiency virus (HIV)-positive persons with different sexual identities. After controlling for ethnicity, heterosexual men reported fewer symptoms than did either bisexual or gay men and heterosexual women reported fewer symptoms than did bisexual women. Heterosexual and bisexual women reported greater symptom intrusiveness than did heterosexual or gay men. Coping self-efficacy and cognitive depression independently explained symptom reports and symptom intrusiveness for heterosexual, gay, and bisexual men. Coping self-efficacy and cognitive depression explained symptom intrusiveness among heterosexual women. Cognitive depression significantly contributed to the number of symptom reports for heterosexual and bisexual women and to symptom intrusiveness for lesbian and bisexual women. Individuals likely experience HIV differently on the basis of sociocultural realities associated with sexual identity. Further, symptom intrusiveness may be a more sensitive measure of subjective health status for these groups.Behavioral Medicine 02/2009; 34(4):133-44. · 1.14 Impact Factor -
Article: HIV testing rates, testing locations, and healthcare utilization among urban African-American men.
[show abstract] [hide abstract]
ABSTRACT: African-American men bear a disproportionate burden of HIV infection in the United States. HIV testing is essential to ensure that HIV-infected persons are aware of their HIV-positive serostatus, can benefit from early initiation of antiretroviral therapy, and can reduce their risk of transmitting the virus to sex partners. This cross-sectional study assessed HIV testing history and healthcare utilization among 352 young African-American men recruited in urban neighborhoods in a Midwestern city. The self-administered survey measured sexual risk behaviors, factors associated with HIV testing, and barriers to testing. The acceptability of community venues for HIV testing was also assessed. Of the respondents, 76% had been tested for HIV at some time in their lives, 52% during the prior 12 months. Of the participants, 70% had unprotected intercourse during the prior 12 months, 26% with two or more partners. Nearly three-quarters (72%) of participants had seen a healthcare provider during the prior year. In univariate analyses, those who had at least one healthcare provider visit during the prior 12 months and those who had a primary doctor were more likely to have been tested in the prior 12 months. In multivariate analyses, having a regular doctor who recommended HIV testing was the strongest predictor of having been tested [OR=7.38 (3.55, 15.34)]. Having been diagnosed or treated for a sexually transmitted disease also was associated with HIV testing [OR=1.83 (1.04, 3.21)]. The most commonly preferred testing locations were medical settings. However, community venues were acceptable alternatives. Having a primary doctor recommend testing was strongly associated with HIV testing and most HIV testing occurred at doctors' offices. But, a substantial proportion of persons were not tested for HIV, even if seen by a doctor. These results suggest that HIV testing could be increased within the healthcare system by increasing the number of recommendations made by physicians to patients. The use of community venues for HIV testing sites could further increase the number of persons tested for HIV.Journal of Urban Health 01/2009; 86(1):119-31. · 2.13 Impact Factor -
Article: Decision-making at menopause: a randomized controlled trial of a computer-based hormone therapy decision-aid.
[show abstract] [hide abstract]
ABSTRACT: Decision-making at menopause remains a challenge for women and their health care providers as the paradigm for hormone therapy continues to evolve. The role of decision-support for this process remains to be defined. A randomized controlled trial of a computer-based hormone therapy (HT) decision-aid versus a control intervention consisting of a printed pamphlet among 177 post-menopausal women receiving care in a Veterans Affairs Medical Center. Participants found the computer-based decision-aid easy to use and retained risk information incorporated from emerging scientific data. There was no difference between groups with respect to the primary outcomes of knowledge, satisfaction with decision, decisional conflict or HT use. A trend was reported towards decreased decisional conflict in the evidence in decision-making (p=0.07) and factors of uncertainty (p=0.06) domains among the subset of participants who were on HT at baseline and used the computer-based decision-aid. The computer-based decision-aid was able to effectively incorporate emerging scientific information but was no more effective than a printed pamphlet control with regard to improving decision-process outcomes. The incremental benefit of a complex versus simpler decision-aid for post-menopausal women remains to be established prior to widespread dissemination of interactive computer-based HT decision-aids.Patient Education and Counseling 07/2007; 67(1-2):100-7. · 2.31 Impact Factor -
Article: Demographic characteristics, treatment history, drug risk behaviors, and condom use attitudes for U.S. and Russian injection drug users: the need for targeted sexual risk behavior interventions.
[show abstract] [hide abstract]
ABSTRACT: Two separate databases, one on Russian (n = 444) injection drug users (IDUs), and the other on U.S. IDUs (n = 241), were merged, and responses were compared. Results indicated that Russian IDUs perceived themselves to be at greater risk for HIV/AIDS based upon behaviors over the past 90 days. U.S. IDUs were more likely to be tested for HIV, report a negative HIV result, and know more people with HIV. U.S. IDUs consumed greater amounts of alcohol and marijuana, and made more alcohol/drug treatment attempts than Russian IDUs. Russian IDUs injected more frequently, although were more likely to recently use clean needles. Russian and U.S. IDUs responded significantly differently to eight AIDS knowledge questions. Eight condom attitude questions were asked of each group, and each revealed significantly different responses. Gender differences for Russian IDUs were also observed. There is a clear need to create culturally targeted sexual risk reduction interventions.AIDS and Behavior 04/2005; 9(1):111-20. · 3.49 Impact Factor -
Article: Predictors of risky sex of young men after release from prison.
[show abstract] [hide abstract]
ABSTRACT: A longitudinal study of demographic and behavioural characteristics associated with risky sexual behaviours of young men after release from prison. One hundred and six men were interviewed in prison and at one week and six months after release. Overall, 37% reported a previous sexually transmitted disease (STD) diagnosis. In the 30 days before incarceration, 33% had had sex with a risky partner, and 59% had had multiple female sex partners. After release, 38 (36%) men reported having had risky sex (>or=2 female sex partners and unprotected vaginal sex): 12 (13%) at one week and 31 (34%) at six months. The only factor independently associated with risky sex was the use of alcohol/drugs before sex: one-week odds ratio (OR)=6.11 (95% confidence interval [CI]: 1.42-26.40), six-month OR=3.05 (95% CI: 1.30-9.42). Behavioural intervention programmes for incarcerated men should address drug and alcohol use and its contribution to higher risk for HIV and STDs.International Journal of STD & AIDS 08/2003; 14(8):519-23. · 1.09 Impact Factor -
Article: Characteristics and predictors of HIV risk behaviors among injection-drug-using men and women in St. Petersburg, Russia.
[show abstract] [hide abstract]
ABSTRACT: The purpose of this study was to establish the prevalence of high-risk sexual behaviors and drug-using behaviors in a large community sample of male and female injection drug users (IDUs) in St. Petersburg, Russia. This investigation used a data collection plan that systematically recruited a drug user sample from venues where IDUs were known to congregate and could be accessed. Surveys were completed by 239 IDUs (males = 139, females = 100), aged 13-25. Participants averaged 44 injections (range = 0-240) in the past 30 days, with heroin (70%) and heroin plus other drugs (20%) the most frequently used. Participants' mean age of first drug injecting was 17.6 years, 41% of participants regularly shared needles, most had multiple sexual partners (mean = 9.3 partners in the past 3 months), and 70% reported engaging in vaginal intercourse without condoms. Stepwise logistic regression showed that high-risk sexual behavior was predicted by being female, young, using heroin several times a month, and less negative attitudes toward using condoms. Effective HIV prevention efforts for IDUs in Russia must be tailored to their age, gender, drug use, and condom attitudes. These programs will also have to address the dual risk factors, unique to IDUs, of risky sexual behaviors and needle sharing. Without a rapid intervention response, Russia's HIV/AIDS crisis will soon turn catastrophic.AIDS Education and Prevention 09/2002; 14(4):295-305. · 1.59 Impact Factor
