Background: Audio computer assisted self interview (ACASI) may minimise social desirability bias in the ascertainment of sensitive behaviours. The aim of this study was to describe the difference in reporting risk behaviour in ACASI compared to a face to face interview (FFI) among public sexually transmitted diseases (STD) clinic attendees. Study design: Randomly selected patients attending a public STD clinic in Baltimore, Maryland, sequentially took an ACASI formatted risk behaviour assessment followed by an FFI conducted by a single clinician, with both interview modalities surveying sexual and drug use behaviours. Binary responses were compared using the sign test, and categorical responses were compared using the Wilcoxon signed rank test to account for repeated measures. Results: 671 (52% men, mean age 30 years, 95% African American) of 795 clinic attendees screened consented to participate. Subjects affirmed sensitive sexual behaviours such as same sex contact (p = 0.012), receptive rectal sexual exposure (p,0.001), orogenital contact (p,0.001), and a greater number of sex partners in the past month (p,0.001) more frequently with ACASI than with an FFI. However, there were no differences in participant responses to questions on use of illicit drugs or needle sharing. Conclusions: Among STD clinic patients, reporting of sensitive sexual risk behaviours to clinicians was much more susceptible to social desirability bias than was reporting of illegal drug use behaviours. In STD clinics where screening of sexual risk is an essential component of STD prevention, the use of ACASI may be a more reliable assessment method than traditional FFI.

Background. Policymakers need estimates of the impact of tobacco control (TC) policies to set priorities and targets for reducing tobacco use. We systematically reviewed the independent effects of TC policies on smoking behavior. Methods. We searched MEDLINE (through January 2012) and EMBASE and other databases through February 2009, looking for studies published after 1989 in any language that assessed the effects of each TC intervention on smoking prevalence, initiation, cessation, or price participation elasticity. Paired reviewers extracted data from studies that isolated the impact of a single TC intervention. Findings. We included 84 studies. The strength of evidence quantifying the independent effect on smoking prevalence was high for increasing tobacco prices and moderate for smoking bans in public places and antitobacco mass media campaigns. Limited direct evidence was available to quantify the effects of health warning labels and bans on advertising and sponsorship. Studies were too heterogeneous to pool effect estimates. Interpretations. We found evidence of an independent effect for several TC policies on smoking prevalence. However, we could not derive precise estimates of the effects across different settings because of variability in the characteristics of the intervention, level of policy enforcement, and underlying tobacco control environment.

Evidence supporting the use of Web-based interventions for smoking cessation is insufficient to moderate in adults and insufficient in college students and adolescents. These RCTs have, however, elucidated clinical, methodological, and statistical practices that are likely to improve future trial design and treatment delivery.

Background Binge drinking is associated with risky sexual behaviors and STDs. Few studies have investigated this by gender or in an STD clinic. This cross-sectional study examined the association between binge drinking and risky sexual behaviors/STDs among patients attending an urban STD clinic. Method 671 STD clinic patients were tested for STDs, and queried about recent alcohol/drug use and risky sexual behaviors using audio computer-assisted-self-interview. The association between binge drinking and sexual behaviors/STDs was analyzed using logistic regression adjusting for age, employment, and drug use. Results Binge drinking was reported by 30% of women and 42% of men. Gender differences were found in rates of receptive anal sex which increased linearly with increased alcohol use among women but did not differ among men. Within gender analyses showed that women binge drinkers engaged in anal sex at more than twice the rate of women who drank alcohol without binges(33.3% vs. 15.9%;p<.05) and three times the rate of women who abstained from alcohol(11.1%;p<.05). Having multiple sex partners was more than twice as common among women binge drinkers than women abstainers(40.5% vs. 16.8%;p<.05). Gonorrhea was nearly 5 times higher among women binge drinkers compared to women abstainers(10.6% vs.2.2%;p<.05). The association between binge drinking and sexual behaviors/gonorrhea remained after controlling for drug use. Among men, rates of risky sexual behaviors/STDs were high, but did not differ by alcohol use. Conclusion Rates of binge drinking among STD clinic patients were high. Among women, binge drinking was uniquely associated with risky sexual behaviors and an STD diagnosis. Our findings support the need to routinely screen for binge drinking as part of clinical care in STD clinics. Women binge drinkers, in particular, may benefit from interventions that jointly address binge drinking and risky sexual behaviors. Developing gender-specific interventions could improve overall health outcomes in this population.

Depression in STD clinic patients is associated with HIV risk behaviors but not STD diagnosis. Identifying depression and developing strategies to intervene effectively may reduce HIV risk behaviors and improve health outcomes.

HIV risk behaviors before incarceration were highly prevalent among the women in this study. Rates of PTSD, depression, and dysthymic disorder were also high. PTSD was associated with prostitution and receptive anal sex, and the disorder may contribute to high rates of risky sexual behavior. Targeted HIV risk reduction efforts among women prisoners should include evaluation for PTSD; conversely, women prisoners with a diagnosis of PTSD should be evaluated for prior HIV sexual risk behaviors.

Objective Hazardous alcohol use by HIV-infected women is associated with poor HIV outcomes and HIV transmission risk behaviors. We examined the effectiveness of brief alcohol intervention (BI) among hazardous drinking women receiving care in an urban, HIV clinic. Methods Women were randomized to a 2-session BI or usual care. Outcomes assessed at baseline, 3, 6 and 12 months included 90-day frequency of any alcohol use and heavy/binge drinking (≥4 drinks per occasion), and average drinks per drinking episode. Secondary outcomes included HIV medication and appointment adherence, HIV1-RNA suppression, and days of unprotected vaginal sex. We examined intervention effectiveness using generalized mixed effect models and quantile regression. Results Of 148 eligible women, 74 were randomized to each arm. In mixed effects models, 90-day drinking frequency decreased among intervention group compared to control, with women in the intervention condition less likely to have a drinking day (OR: 0.42 (95% CI: 0.23–0.75). Heavy/binge drinking days and drinks per drinking day did not differ significantly between groups. Quantile regression demonstrated a decrease in drinking frequency in the middle to upper ranges of the distribution of drinking days and heavy/binge drinking days that differed significantly between intervention and control conditions. At follow-up, the intervention group had significantly fewer episodes of unprotected vaginal sex. No intervention effects were observed for other outcomes. Conclusions Brief alcohol intervention reduces frequency of alcohol use and unprotected vaginal sex among HIV-infected women. More intensive services may be needed to lower drinks per drinking day and enhance care for more severely affected drinkers.

BackgroundPersons living with HIV and substance use disorders face barriers to sustained engagement in medical care, leading to suboptimal antiretroviral treatment outcomes. Innovative mobile technology tools such as customizable smartphone applications have the potential to enhance existing care coordination programs, but have not been rigorously studied.MethodsWe developed and implemented a two-component intervention consisting of peer health navigation supported by a smartphone application conducting ecologic momentary assessment (EMA) of barriers to care and medication adherence. Patients with a history of antiretroviral treatment failure and substance use were recruited to participate in the 9-month pilot intervention. Three peer health navigators were trained to provide social and logistical support while participants re-engaged in HIV care. We assessed the acceptability of the intervention components using qualitative analysis of in-depth interviews conducted with study participants and peer navigators.ResultsOf 19 patients enrolled in the study, 17 participated for at least 2 months and 15 completed the entire 9-month study protocol. The acceptability of the peer navigation intervention was rated favorably by all participants interviewed, who felt that peer support was instrumental in helping them re-engage in HIV care. Participants also responded favorably to the smartphone application, but described its usefulness mostly as providing reminders to take medications and attend appointments, rather than as a facilitator of patient navigation.ConclusionsPeer health navigation and smartphone-based EMA are acceptable approaches to facilitating engagement in HIV care for drug using populations. Future studies to evaluate the efficacy of this approach for improving long-term retention in care and antiretroviral treatment outcomes are warranted.
