Predictive factors for vaginal douching and tampon use among US women: Are these behaviors risk factors for bacterial vaginosis and trichomonas?

The use of feminine products such as vaginal douches, tampons, and sanitary napkins are common among women. Despite the results of some studies that suggest an association between douching and bacterial vaginosis, douching remains a topic that is understudied. The possibility of an association between tampon use and infection has not been significantly investigated since the toxic shock outbreak in the 1980s. The first objective of our study was to evaluate demographic, reproductive health, and sexual behavior variables to establish an epidemiologic profile of menstruating women who reported douching and women who reported using sanitary napkins only. The second objective of our study was to evaluate whether the behaviors of douching and using tampons were associated with an increased risk of bacterial vaginosis or trichomonas. We analyzed these factors, using logistic regression, among the 3,174 women from the NHANES cross sectional data from 2001-2004, who met the inclusion criteria determined for our study. We established an epidemiologic profile for women who had the highest frequency of douching reported as women who were age 36-49, had a high school education or GED, black race, not taking oral contraceptives, reported vaginal symptoms in the last month, two or more sexual partners in the last year, or tested positive for bacterial vaginosis or trichomonas. The profile for those who had the highest frequency of exclusive sanitary napkin use included women with less than a high school education, married women, women classified as black or "other" in race, and women who were not on oral contraceptives. While we were able to establish a significant increase in the odds of douching among women who tested positive for bacterial vaginosis or trichomonas, we did not find any significant difference in the odds of exclusive napkin use and testing negative for bacterial vaginosis or trichomonas.^

The influence of HIV/AIDS on the association between genital human papillomavirus and cervical cancer in HIV/AIDS infected women: A literature review

Background: With over 440 million cases of infections worldwide, genital HPV is the most frequent sexually transmitted infection. There are several types including high risk types 16, 18, 58 and 70 among others, which are known to cause cervical cell abnormality and if persistent, can lead to cervical cancer which globally, claims 288,000 lives annually. 33.4 million people worldwide are currently living with HIV/AIDS, with 22.4 million in sub-Saharan Africa where 70% of the female population living with HIV/AIDS is also found. Similar risk factors for HPV, cervical cancer and HIV/AIDS include early age at sexual debut, multiple sexual partners, infrequent condom use, history of STI and immune-suppression. ^ Objectives: To describe the role of HPV in cervical cancer development, to describe the influence of HIV/AIDS on HPV and in the development of cervical cancer and to describe the importance of preventive measures such as screening. ^ Methods: This is a literature review where data were analyzed qualitatively and a descriptive narrative style used to evaluate and present the information. The data came from searches using Pub Med, Cochrane Library, EBSCO Medline databases as well as websites such as the CDC and WHO. Articles selected were published in English over the last 10 years. Keywords used included: 'HPV, cervical cancer and HIV', 'HIV and HPV', 'HPV and cervical cancer', 'HPV infection', 'HPV vaccine', 'genital HPV', 'HIV and cervical cancer', 'prevalence of HIV and cervical cancer' and 'prevalence of cervical cancer'. ^ Results: Women with HIV/AIDS have multiple HPV types, persistent infection, are more likely to present with cervical neoplasia and are at higher risk for cervical cancer. Research also shows that HIV could affect the transmissibility of HPV and that HPV itself could also increase the susceptibility to HIV acquisition. ^ Conclusion: HIV, genital HPV and cervical cancer are all preventable. Need to emphasize programs that aim to increase HIV/AIDS, HPV and cervical cancer awareness. Stress importance of behavior modification such as frequent use of condoms, decreased sexual partners and delayed first intercourse. Facilitate programs for screening and treating HPV, male circumcision, effective management of HAART and HPV vaccination.^

Nutritional factors and the risk of cervical dysplasia

A case comparison study of 159 women was conducted to test the hypotheses that women with cervical dysplasia had a higher prevalence of low dietary intakes of carotenoids, vitamin C, and folacin than women without cervical dysplasia, and that there would be no association between the risk of having cervical dysplasia and dietary intake of retinol. Information regarding the prevalence of known risk factors for cervical dysplasia, early age at first intercourse, multiple sexual partners, early age at first pregnancy, history of having sexually transmitted diseases, cigarette smoking, and sociodemographic data was collected. Dietary intake was estimated using a 97 item quantified food frequency questionnaire designed to obtain information on consumption of all sources of retinol, carotenoids, vitamin C and folacin. Univariate analyses showed that the presence of cervical dysplasia was positively and significantly associated with all the risk factors. In analyses of the association of the dietary variables with cervical dysplasia, information on carotenoid intake was calculated in two ways, as total carotenoid intake and as intake of lycopene and other carotenoids. While there appeared to be an inverse association between the presence of cervical dysplasia and intakes of lycopene and folacin, lower intake of retinol, total carotenoids, other carotenoids (non-lycopene carotenoids) or vitamin C did not increase the risk of having cervical dysplasia. Multivariable analyses showed that, in comparison to women who usually consume 105 RE/day of lycopene, the odds of having cervical dysplasia for women who consume 31-104 RE/day and 30 RE/day or less were 1.31 and 1.66 respectively. The odds of having cervical dysplasia in women who consume 199-396 mcg/day and 198 mcg/day or less of folacin were 2.66 and 2.97 respectively as compared to women who usually consume 397 mcg/day or more. These results suggest the importance of re-evaluating existing dietary data and planning in future studies to evaluate the associations of lycopene and folacin with cervical cancer, as well as to extend these results to other diet/cancer investigations. ^

Cigarette smoking and cervical intraepithelial neoplasia among colposcopy patients

Epidemiologic and biochemical evidence suggest that smoking is an independent risk factor for cervical neoplasia; however, only two studies have adjusted by the potential confounding effect of human papillomavirus (HPV). To determine the association between self-reported current cigarette smoking and cervical intraepithelial neoplasia (CIN), we conducted a case-control study that controlled for HPV infection and other reported risk factors. The medical records of all new patients referred to the University of Texas M. D. Anderson Cancer Center (UTMDACC) Colposcopy Clinic were reviewed. The study population (n = 564) consisted of all white, black, and Hispanic non-pregnant women who were residents of Texas, and had no history of treatment for cervical neoplasia. Cases (n = 313) included women diagnosed at the UTMDACC with CIN; while controls (n = 251) included those patients diagnosed at the colposcopy clinic as non-CIN (negative 47%, inflammation or atypia 25%, and koilocytosis 27%). Diagnosis was based on a colposcopically directed biopsy in 95% of the subjects, and all subjects were tested for HPV by dot blot hybridization. The crude odds ratio for cigarette smoking and CIN was 1.37 (95% CI 0.97-1.95); however, after adjusting for HPV, age, education, race, number of sexual partners, and age at first sexual intercourse, the odds ratio decreased to 0.91 (95% CI 0.61-1.41). A higher crude odds ratio was observed with CIN 3 (OR = 1.75, 95% CI 1.08-2.83), but this effect also disappeared after adjustment (OR = 1.06, 95% CI 0.57-1.96). Similar results were observed when controlling only for HPV: OR = 1.11 (95% CI 0.77-1.59) for CIN combined and 1.25 (95% CI 0.76-2.08) for CIN 3. These findings suggest that cigarette smoking is not an independent risk factor for CIN in this population, and that HPV may be an important confounding factor for this association. ^

Prevalence of HIV risk-related behaviors among undocumented Central American immigrant women in Houston, Texas, 2010

The primary aim of this dissertation research is to provide epidemiological data on HIV risk-related behaviors among undocumented Central American immigrant women living in Houston, Texas. Between February and May 2010, we used respondent driven sampling (RDS) to recruit 230 Guatemalan, Honduran, and El Salvadoran women, ages 18 to 50 years, living in Houston without a valid United States visa or residency papers. RDS is a probability-based sampling method that utilizes social networks to access members of hidden populations that lack a sampling frame. Participants completed an interview regarding their demographics, access to and utilization of healthcare services, HIV testing, and sexual behaviors. Data from this study were used 1) to describe the prevalence of sexual HIV risk-related behaviors among undocumented Central American immigrant women, comparing those who recently immigrated to the U.S. (within the past five years) to those with more established residency (of over five years); 2) to describe the prevalence of lifetime HIV testing and evaluate its associated factors in this target population; and 3) to describe the effectiveness of RDS to access members of this target population. ^ As described in Paper 1, there was a generally low prevalence of individual HIV risk-related behaviors (i.e., multiple, concurrent, convenience, and casual sexual partnerships) among the undocumented Central American immigrant women in this study. However, there was evidence of HIV risk due to unprotected sex with male partners who have concurrent sexual partnerships. We identified recent immigrants as the subpopulation at greatest risk, as they were significantly more likely than established immigrants to have multiple and/or concurrent sexual partners. As described in Paper 2, the lifetime prevalence of HIV testing was almost 70%. After adjusting for age, number of years living in the U.S., income security, and resource barriers, lifetime HIV testing was significantly associated with being from Honduras, having more than a sixth grade education, having a regular healthcare provider, and having knowledge of available healthcare resources. Finally, as described in Paper 3, RDS was an effective method for obtaining a diverse sample of Central American immigrant women in Houston. ^ This project is the first to use RDS to conduct an HIV behavioral survey among undocumented Central American immigrant women. Our results will inform the design of future research studies and the implementation of HIV prevention activities among undocumented Central American immigrants in the U.S.^

HIV prevalence and contextual risk-factors among injection drug users in Harris County, Texas

Injection drug use is the third most frequent risk factor for new HIV infections in the United States. A dual mode of exposure: unsafe drug using practices and risky sexual behaviors underlies injection drug users' (IDUs) risk for HIV infection. This research study aims to characterize patterns of drug use and sexual behaviors and to examine the social contexts associated with risk behaviors among a sample of injection drug users. ^ This cross-sectional study includes 523 eligible injection drug users from Houston, Texas, recruited into the 2009 National HIV Behavioral Surveillance project. Three separate set of analyses were carried out. First, using latent class analysis (LCA) and maximum likelihood we identified classes of behavior describing levels of HIV risk, from nine drug and sexual behaviors. Second, eight separate multivariable regression models were built to examine the odds of reporting a given risk behavior. We constructed the most parsimonious multivariable model using a manual backward stepwise process. Third, we examined whether HIV serostatus knowledge (self-reported positive, negative, or unknown serostatus) is associated with drug use and sexual HIV risk behaviors. ^ Participants were mostly male, older, and non-Hispanic Black. Forty-two percent of our sample had behaviors putting them at high risk, 25% at moderate risk, and 33% at low risk for HIV infection. Individuals in the High-risk group had the highest probability of risky behaviors, categorized as almost always sharing needles (0.93), seldom using condoms (0.10), reporting recent exchange sex partners (0.90), and practicing anal sex (0.34). We observed that unsafe injecting practices were associated with high risk sexual behaviors. IDUs who shared needles had higher odds of having anal sex (OR=2.89, 95%CI: 1.69-4.92) and unprotected sex (OR=2.66, 95%CI: 1.38-5.10) at last sex. Additionally, homelessness was associated with needle sharing (OR=2.24, 95% CI: 1.34-3.76) and cocaine use was associated with multiple sex partners (OR=1.82, 95% CI: 1.07-3.11). Furthermore, twenty-one percent of the sample was unaware of their HIV serostatus. The three groups were not different from each other in terms of drug-use behaviors: always using a new sterile needle, or in sharing needles or drug preparation equipment. However, IDUs unaware of their HIV serostatus were 33% more likely to report having more than three sexual partners in the past 12 months; 45% more likely to report to have unprotected sex and 85% more likely to use drug and or alcohol during or before at last sex compared to HIV-positive IDUs. ^ This analysis underscores the merit of LCA approach to empirically categorize injection drug users into distinct classes and identify their risk pattern using multiple indicators and our results show considerable overlap of high risk sexual and drug use behaviors among the high-risk class members. The observed clustering pattern of drug and sexual risk behavior among this population confirms that injection drug users do not represent a homogeneous population in terms of HIV risk. These findings will help develop tailored prevention programs.^

A comparison of health behaviors of African -American male and female illicit drug users: Implications for community health practice

Prevalence of drug use, HIV, syphilis, and other STDs is particularly high in African-American populations. Although some studies have documented protective changes in health behaviors relevant to these outcomes, other research indicates that risky health behaviors are still widespread. Moreover, little is known about how African-American men and women have differed in their responses to calls to adopt protective behaviors. The study reported in this dissertation investigates gender differences in health risk behavior in a sample of 482 African American chronic, frequent injection drug and crack cocaine users residing in Houston, Texas. It uses baseline and 9 month follow-up data collected on this sample. Four major research questions are addressed. These questions are: Research question 1. What was the overall pattern of reduction in drug use for subjects in the sample? In particular, did subjects who reported a recent (30 day) reduction in drug use and needle sharing risk at baseline also report a reduction at follow-up? Research question 2. Is gender significantly associated with the overall pattern of risk reduction in drug injection observed in the two waves of the study? Research question 3. Is gender significantly associated with the overall pattern of reduction in the number of sexual partners observed in the two waves of the study? Research question 4. Is gender significantly associated with the overall pattern of increase in the use of barrier contraceptives in the two waves of the study? ^

Sida y mujer : un análisis prospectivo de las causas de la infección del VIH/SIDA en las mujeres

El presente informe es el resultado de la investigación prospectiva realizada en mujeres infectadas por VIH/SIDA como tema de tesis de Magíster Políticas Sociales y Gestión Local defendida el 25 de noviembre de 2002 en el aula magna de la Facultad de Ciencias Políticas y Sociales, UNC. El SIDA no es sólo una enfermedad biológica sino que tiene una fuerte incidencia en lo social. La intención de este trabajo es despertar la inquietud para que las personas se movilicen a trabajar en la prevención y la asistencia, buscando respuestas alternativas que le faciliten al ser humano la posibilidad de tener una vida más digna. Las estadísticas nacionales demuestran una marcada feminización de esta epidemia. Las formas que asume la sexualidad son muy variadas y están determinadas por el tiempo y lugar donde vivimos. Las mujeres sufren una falta de contención de sus parejas sexuales con escasa toma de conciencia de la posibilidad de progresión de la enfermedad si no se utilizan métodos de barrera, que está íntimamente relacionado con la falta de educación sexual, también en el varón. Como conclusión, podemos decir que el 63,9% de las mujeres no utilizan métodos anticonceptivos debido a temores y prejuicios provocados por la falta de educación sexual. El 75,3% proviene de la negativa del varón a usar preservativo y el 100 % de las mujeres, a pedir el uso del preservativo por vergüenza o miedo. Todo esto nos está demostrando el poco diálogo con sus parejas sexuales y, por parte del hombre, la no protección de la mujer como madre, compañera y miembro útil de la sociedad.

Alcohol use and risk taking among regular ecstasy users

We examine alcohol use in conjunction with ecstasy use and risk-taking behaviors among regular ecstasy users in every capital city in Australia. Data on drug use and risks were collected in 2004 from a national sample of 852 regular ecstasy users (persons who had used ecstasy at least monthly in the preceding 6 months). Users were grouped according to their typical alcohol use when using ecstasy: no use, consumption of between one and five standard drinks, and consumption of more than five drinks (binge alcohol use). The sample was young, well educated, and mainly working or studying. Approximately two thirds (65%) of the regular ecstasy users reported drinking alcohol when taking ecstasy. Of these, 69% reported usually consuming more than five standard drinks. Those who did not drink alcohol were more disadvantaged, with greater levels of unemployment, less education, higher rates of drug user treatment, and prison history. They were also more likely than those who drank alcohol when using ecstasy to be drug injectors and to be hepatitis C positive. Excluding alcohol, drug use patterns were similar between groups, although the no alcohol group used cannabis and methamphetamine more frequently. Binge drinkers were more likely to report having had three or more sexual partners in the past 6 months and were less likely to report having safe sex with casual partners while under the influence of drugs. Despite some evidence that the no alcohol group were more entrenched drug users, those who typically drank alcohol when taking ecstasy were as likely to report risks and problems associated with their drug use. It appears that regular ecstasy users who binge drink are placing themselves at increased sexual risk when under the influence of drugs. Safe sex messages should address the sexual risk associated with substance use and should be tailored to reducing alcohol consumption, particularly targeting heavy alcohol users. The study's limitations are noted.

DO VIRTUAL AO REAL: COMUNICAÇÃO, SEXO E INTERNET

Este trabalho é um estudo exploratório sobre o Ambiente Comunicacional Internet que investiga tanto a possibilidade da influência de suas ferramentas de interação/comunicação sobre o comportamento sexual e de risco quanto o desenvolvimento de comportamento compulsivo no uso destas ferramentas na busca de parceiros sexuais. A metodologia adotada é, além da pesquisa bibliográfica, a da pesquisa exploratória, um levantamento e análise de dados quantitativos e pode ser considerada como pertencente ao paradigma tradicional empírico, pois a coleta de dados foi baseada em respostas a questionários semi-estruturados, aplicados a um grupo de informação composto por 428 estudantes universitários dos cursos ligados à área de Computação e Informática de uma instituição particular de Ensino Superior do município de São Paulo SP, Brasil. Para isso, obedece à Resolução do Conselho Nacional de Saúde CNS 196/96 e conta com o TCLE. Os resultados indicam que as práticas sexuais, a exposição a DST e vírus HIV e, particularmente, a tendência ao desenvolvimento do Transtorno de Adicção à Internet se distinguem de modo irrefutável. Os participantes que alegaram buscar parceiros sexuais reais na Internet são diretos nos seus objetivos, pois quando encontram esse parceiro concretizam o ato sexual, em ambientes impessoais, como por exemplo, o motel, e muitas vezes de modo arriscado no que toca à prevenção e à segurança no contato com outro. Destaca-se, ainda, que a compulsão não é reconhecida pelo grupo e que a procura de parceiros por intermédio das mídias digitais, para esse grupo, não está relacionada a itens negativos quanto a sua qualidade de vida o que suscita o estudo e a discussão mais aprofundada sobre a interação comunicação, sexo e Internet .(AU)

EFICÁCIA ADAPTATIVA E SITUAÇÕES DE CRISE EM PORTADORES DO VÍRUS HIV IMUNODEFICIÊNCIA HUMANA / AIDS.

O objetivo desta pesquisa foi investigar a eficácia adaptativa e situações de crise de indivíduos portadores do vírus HIV do Programa Municipal DST/AIDS de Aparecida SP. O instrumento utilizado foi a Entrevista Clínica Preventiva - EDAO (Escala Diagnóstica Adaptativa Operacionalizada). Participaram do estudo 5 homens e 5 mulheres que freqüentavam o serviço de saúde. Os resultados do trabalho revelaram que ser portador de uma doença crônica carregada de estigmas como a AIDS é um fator desestruturante para o diagnóstico. Foi percebida na população estudada o comprometimento dos setores afetivo-relacional e produtividade, seguido do sóciocultural. Foram observados alguns aspectos importantes como: a crise do impacto diagnóstico como sendo algo marcante em todos os participantes, bem como o uso de drogas, comportamentos vulneráveis que possivelmente levaram à infecção pelo vírus HIV, dificuldades de resolução de conflitos e nas relações interpessoais, perdas vivenciadas durante toda a vida e também no decorrer da infecção e o fenômeno da feminização do vírus HIV através das mulheres entrevistadas, que foram infectadas por seus parceiros sexuais estáveis. No setor orgânico de funcionamento, a população estudada mostrou adesão ao tratamento A maioria da população estudada foi diagnosticada com adaptação ineficaz severa. Este estudo trouxe questionamentos importantes sobre a maneira com a qual o indivíduo portador do vírus HIV mantém seu equilíbrio psíquico e suas relações com o trabalho que executa, chamando atenção para a necessidade de outros estudos que contemplem diferentes instrumentos para a compreensão do tema.

Sex and diabetes:a thematic analysis of gay and bisexual men's accounts

Around 50 per cent of men with diabetes experience erectile dysfunction. Much of the literature focuses on quality of life measures with heterosexual men in monogamous relationships. This study explores gay and bisexual men's experiences of sex and diabetes. Thirteen interviews were analysed and three themes identified: erectile problems; other 'physical' problems; and disclosing diabetes to sexual partners. Findings highlight a range of sexual problems experienced by non-heterosexual men and the significance of the cultural and relational context in which they are situated. The personalized care promised by the UK government should acknowledge the diversity of sexual practices which might be affected by diabetes.

Knowledge and perceptions about HIV/AIDS and safer sex practices among Korean-Americans in Dade County, Florida

This study was conducted to identify Korean-Americans' knowledge, perceptions, and efficacy (both self and response) relating to HIV/AIDS, as well as safer sex practices. Age, gender, education, Confucianism, religion, and acculturation were also examined for potential relationships with the main variables. A total of 200 Korean-Americans in Dade County, Florida, participated in the study. The mean age of the participants was 32.6 years (range 19-55). The AIDS Risk Assessment Questionnaire (ARA-Q) derived from the AIDS Risk Measurement Study Questionnaire (ARMS-Q) and the Risk Behavior Assessment (RBA) were used for data collection. The overall mean score of HIV/AIDS knowledge was 12.3 (77%) out of a possible 16. Knowledge, and perceptions about HIV/AIDS were not related to safer sex practices. Significant correlations between attitudes toward condoms and the frequency of condom use during oral intercourse were evident. Male subjects reported more sexual partners in their lifetime and more frequent condom use during vaginal intercourse during the last year than female subjects. The number of sexual partners in the last year was not related to perceived HIV/AIDS susceptibility and response-efficacy among men or women, but response-efficacy positively correlated to frequency of condom use among both genders. Acculturation scores were positively correlated with the number of sexual partners and the frequency of condom use during vaginal intercourse for men and women. Further research is needed to determine factors that may increase the cultural relevance of AIDS prevention strategies to the Korean-American community. The findings of this study may be used as a basis for designing culturally-sensitive HIV/AIDS education programs to reach various segments of this ethnic community. ^

Correlates of voluntary HIV testing and counseling among middle aged and older Latinas

This study identifies and describes HIV Voluntary Counseling and Testing (VCT) of middle aged and older Latinas. The rate of new cases of HIV in people age 45 and older is rapidly increasing, with a 40.6% increase in the numbers of older Latinas infected with HIV between 1998 and 2002. Despite this increase, there is paucity of research on this population. This research seeks to address the gap through a secondary data analysis of Latina women. The aim of this study is twofold: (1) Develop and empirically test a multivariate model of VCT utilization for middle aged and older Latinas; (2) To test how the three individual components of the Andersen Behavioral Model impact VCT for middle aged and older Latinas. The study is organized around the three major domains of the Andersen Behavioral Model of service use that include: (a) predisposing factors; (b) enabling characteristics and (c) need. Logistic regression using structural equation modeling techniques were used to test multivariate relationships of variables on VCT for a sample of 135 middle age and older Latinas residing in Miami-Dade County, Florida. Over 60% of participants had been tested for HIV. Provider endorsement was found to he the strongest predictor of VCT (odds ration [OR] 6.38), followed by having a clinic as a regular source of healthcare (OR=3.88). Significant negative associations with VCT included self rated health status (OR=.592); Age (OR=.927); Spanish proficiency (OR=.927); number of sexual partners (OR=.613) and consumption of alcohol during sexual activity (.549). As this line of inquiry provides a critical glimpse into the VCT of older Latinas, recommendations for enhanced service provision and research will he offered.

Social factors influencing antiretroviral therapy (ART) adherence among Black men living with HIV who use illicit drugs

In the United States 1.2 million persons are HIV infected. Among men, HIV rates in Blacks are seven times higher than Whites. More Black men progress to AIDS because of treatment failure and adherence problems. Antiretroviral therapy (ART), the only treatment effective for long term HIV suppression, requires near perfect adherence. Illicit drug use and homelessness pose further challenges. Suboptimal ART adherence leads to HIV mutations that can render entire classes of medication ineffective and transmission of mutated HIV to others in the community. The purpose of this study was to investigate ART adherence behaviors of Black men living with HIV who use illicit drugs. A sample of 160 Black men living with HIV who use illicit drugs was recruited using flyers and snowball sampling. These men completed study questionnaires that included: demographics, the K-10, PSOM and Social Capital Integrated Questionnaire, among others. One-way ANOVAs, multiple regression, and path analysis were used to address the study's research questions. Most of the Black men in this sample were high school graduates and single, with high rates of being marginally housed and homeless. Unemployment and disability were common, and personal and household income was low. The men reported high numbers of sexual partners both over the past year and during their lifetimes, suggesting continued engagement in high risk behaviors. The majority of the men attributed their HIV to heterosexual sex, with sexual commoditization being common. About half of the 105 men currently taking ART reported the current regimen was their first. Patient-provider relationship was positively associated with tolerability of ART. ART adherence was greater with less psychological distress, lower frequency of current illicit drug use, and greater tolerability of ART. Partner status negatively influenced ART adherence. This study of Black men's ART adherence behaviors has implications for public health. It identified social context factors that influence ART adherence among the men and provides evidence to refine existing, or develop new, ART adherence interventions.
