Structural interventions refer to public health interventions that promote health by altering the structural context within which health is produced and reproduced. They draw on concepts from multiple disciplines, including public health, psychiatry, and psychology, in which attention to interventions is common, and sociology and political economy, where structure is a familiar, if contested, concept. This has meant that even as discussions of structural interventions bring together researchers from various fields, they can get stalled in debates over definitions. In this paper, we seek to move these discussions forward by highlighting a number of critical issues raised by structural interventions, and the subsequent implications of these for research.
The Center for Adherence Support Evaluation (CASE) Adherence Index, a simple composite measure of self-reported antiretroviral therapy (ART) adherence, was compared to a standard threeday self-reported adherence measure among participants in a longitudinal, prospective cross-site evaluation of 12 adherence programs throughout the United States. The CASE Adherence Index, consisting of three unique adherence questions developed for the cross-site study, along with a threeday adherence self-report were administered by interviews every three months over a one-year period. Data from the three cross-site adherence questions (individually and in combination) were compared to three-day self-report data and HIV RNA and CD4 outcomes in cross-sectional analyses. The CASE Adherence Index correlated strongly with the three-day self-reported adherence data (p < 0.001) and was more strongly associated with HIV outcomes, including a 1-log decline in HIV RNA level (maximum OR = 2.34; p < 0.05), HIV RNA<400 copies/ml (maximum OR = 2.33; p < 0.05) and performed as well as the three-day self-report when predicting CD4 count status. Participants with a CASE Index score >10 achieved a 98 cell mean increase in CD4 count over 12 months, compared to a 41 cell increase for those with scores ≤10 (p < 0.05). The CASE Adherence Index is an easy to
Background Engagement in HIV care helps to maximize viral suppression, which, in turn, reduces morbidity and mortality and prevents further HIV transmission. With more HIV cases than any other US city, New York City reported in 2012 that only 41% of all persons estimated to be living with HIV (PLWH) had a suppressed viral load, while nearly three-quarters of those in clinical care achieved viral suppression. Thus, retaining PLWH in HIV care addresses this central goal of both the US National HIV/AIDS Strategy and Governor Cuomo's plan to end the AIDS epidemic in New York State. Methods We conducted 80 in-depth qualitative interviews with PLWH in four NYC populations that were identified as being inconsistently engaged in HIV medical care: African immigrants, previously incarcerated adults, transgender women, and young men who have sex with men. Results Barriers to and facilitators of HIV care engagement fell into three domains: (1) system factors (e.g., patient-provider relationship, social service agencies, transitions between penal system and community); (2) social factors (e.g., family and other social support; stigma related to HIV, substance use, sexual orientation, gender identity, and incarceration); and (3) individual factors (e.g., mental illness, substance use, resilience). Similarities and differences in these themes across the four populations as well as research and public health implications were identified. Conclusions Engagement in care is maximized when the social challenges confronted by vulnerable groups are addressed; patient-provider communication is strong; and coordinated services are available, including housing, mental health and substance use treatment, and peer navigation.
In Lesotho, men have lower HIV testing rates, less contact with HIV clinical settings, and less knowledge of HIV prevention than women. However, women’s HIV prevalence has consistently remained higher than men’s. This paper explores gender norms, sexual decision-making, and perceptions of HIV among a sample of Basotho men and women in order to understand how these factors influence HIV testing and prevention. Two hundred women and 30 men were interviewed in Lesotho between April–July 2011. Participants reported reluctance among women to share information about HIV prevention and testing with men, and resistance of men to engage with testing and/or prevention services. Findings demonstrate a critical need for educational initiatives for men, among other strategies to engage men with HIV testing and prevention. This study highlights how gender issues shape perceptions of HIV and sexual decision-making and underlines the importance of engaging men along with women in HIV prevention efforts. More studies are needed to determine the most effective strategies to inform and engage men.
We conducted a randomized controlled trial among 305 truck drivers from two North Star Alliance roadside wellness clinics in Kenya to see if offering HIV testing choices would increase HIV testing uptake. Participants were randomized to be offered (1) a provider-administered rapid blood (finger-prick) HIV test (i.e., standard of care [SOC]) or (2) a Choice between SOC or a self-administered oral rapid HIV test with provider supervision in the clinic. Participants in the Choice arm who refused HIV testing in the clinic were offered a test kit for home use with phone-based posttest counseling. We compared HIV test uptake using the Mantel Haenszel odds ratio (OR) adjusting for clinic. Those in the Choice arm had higher odds of HIV test uptake than those in the SOC arm (OR = 1.5), but the difference was not statistically significant (p = 0.189). When adding the option to take an HIV test kit for home use, the Choice arm had significantly greater odds of testing uptake (OR = 2.8, p = 0.002). Of those in the Choice arm who tested, 26.9% selected the SOC test, 64.6% chose supervised self-testing in the clinic, and 8.5% took a test kit for home use. Participants varied in the HIV test they selected when given choices. Importantly, when participants who refused HIV testing in the clinic were offered a test kit for home use, an additional 8.5% tested. Offering truck drivers a variety of HIV testing choices may increase HIV testing uptake in this key population.
Migrant female sex workers (FSWs) are one of the most at-risk populations for HIV in China. This study demonstrates how multiple risk factors are situated and vary by types of sex work environments in a sample of 348 migrant FSWs in Beijing. Participants reported high rates of clients' refusal to use condoms (76%), unsafe sex with both clients (32%), non-paid regular partners (e.g., boyfriend or husband) (76%), and a STI symptom (79%) last year. Only 22% of FSWs had been tested for HIV. Risk factors were compared by three types of sex work environments: (1) entertainment establishments, (2) personal services sectors, and (3) street-based venues, including roadside brothels. Street-based FSWs, compared to the other FSWs, were more likely to be older, married with children, migrate from rural areas, and be arrested by police, and less likely to be educated, have contact with prevention services, be knowledgeable about HIV, and be tested for HIV. The FSWs in entertainment establishments were more likely than streetbased FSWs to have reported being physically, verbally, and/or sexually abused by clients. Multiple discriminant analysis distinguished a profile of two different groups of risk factors: (1) police arrest, lack of protection from violence, access to prevention and health care, and HIV knowledge, and (2) verbal and physical abuse and clients' refusal of condom use. In the massive internal migration in China, disadvantages in economic sectors drive women to become involved in sex work. HIV prevention strategies must target socio-structural factors embedded in sex work environments. Keywordsmigrants; female sex workers; sex work environment; China; HIV preventionChina's open door policy in 1978 toward market-driven economic development led to massive migration from rural to urban areas. In Beijing, an estimated 5.4 million of the 17.4 million city residents in 2007 were migrants (Juan, 2007). Large-scale urbanization also resulted in the reemergence of the sex work industry and a resurgence of sexually transmitted infections (STIs) (Chen et al., 2007;Gil et al, 1996). There are an estimated 10 million FSWs in China (Yang et al., 2005c) As sexual transmission is currently the primary driver of the HIV epidemic in China, the potential spread of HIV via the expanded sexual networks among migrant "floating" populations along with urbanization is of particular concern (Anderson et al., 2003;Yang et al., 2005c). In Li and colleagues' study (2004) of migrants in Beijing, mobility, assessed by the total years of migration and the number of migratory cities, was highly correlated with sexual risk. There have been consistent findings that female migrants reported higher STI rates than male migrants in China (Detels et al., 2003;Liu et al., 2005;Mao & Sun, 1999;Sun, 1997). One of the reasons for this disparity may be women's relative disadvantage to men in socio-economic status, facilitating women's entry into the sex work industry and exposure to other health risks (Huang, 2001;Ren, 1999;Yang & Xia, 2006).
