ABSTRACT

The Foundation for Advancement of International Medical Education and Research (FAIMER), a member of Intealth, offers longitudinal faculty development programs (LFDPs) in health professions education (HPE) and leadership through its International FAIMER Institute (IFI) in the United States and FAIMER Regional Institutes (FRIs) globally. FAIMER fosters mutual collaboration and delineates shared responsibilities for FRI development in partnership with local institutions, using an adapted hub-and-spoke organizational design. This paper describes FAIMER's model, its sustainability, and its impacts at individual, institutional, and national levels. IFI was launched in 2001 in Philadelphia, Pennsylvania, as a 2-year part-time hybrid LFDP; with the COVID-19 pandemic onset, IFI transitioned to a fully online program. Since FAIMER's launch, 11 FRIs developed in Brazil, Chile, China, Egypt, India, Indonesia, and South Africa, each modeled on the IFI curriculum and adapted to local context. The more than 1,600 IFI and FRI graduates (fellows) from over 55 countries now form a global community of health professions educators who have shared exposure to HPE methods and assessment, leadership and management, educational scholarship and research, and project management and evaluation. Across all global locations and program formats, fellows self-reported a similar increase in knowledge and skills in HPE. All programs center on the fellows' institutional projects as experiential learning; these projects have focused primarily on educational methods and curriculum revisions. An increased quality of education was reported as the top impact resulting from fellows' projects. As a result of these programs, fellows have influenced education policy in their countries and established academic societies for HPE, thus contributing to recognition of the HPE academic specialty. FAIMER has successfully developed a sustainable model for advancing HPE globally, creating a vibrant network of health professions educators who have influenced country-specific educational policy and practice. FAIMER's model offers one approach to building global capacity in HPE.

ABSTRACT

INTRODUCTION: HIV-related stigma continues to serve as a major barrier to HIV care. HIV stigma reduction interventions are urgently needed to promote and protect the health of persons living with HIV (PLWH). Resilience has been identified as a potential leverage to mitigate the impact of HIV-related stigma among PLWH. METHODS: We examined whether two resilience measures (i.e., social support and resilience assets and resources [RAR]) moderated the relationship between experienced HIV stigma and the HIV care continuum as well as how they moderated the relationship between the consequences of experienced HIV stigma (CES) and the HIV care continuum among 300 PLWH in Louisiana. Separate bootstrapping analyses were conducted to test for evidence of moderated moderation. RESULTS: Most participants were Black (79%) and had been living with HIV for 10 years or more. A relatively high sample of men who have sex with men (MSM) were enrolled (37%). The most common CES were depression (67%). The most common manifestation of experienced HIV stigma was being gossiped about (53%). Participants reported moderate levels of social support. In terms of RAR, most participants (71%) reported that they knew of groups that could support them in responding to experienced HIV stigma. After adjusting for potential covariates, social support and RAR both significantly moderated the relationship between experienced HIV stigma and length of time since their last HIV care visit, B(SE) = .003(.001), p = .03. At high levels of RAR and high levels of social support, those with higher levels of experienced HIV stigma reported a longer length of time since their last HIV care visit than those who reported lower levels of experienced HIV stigma (B(SE) = .17(.04), p < .001). RAR moderated the relationship between social support and HIV care, B(SE) = .01(.004), p < .001. Those who experienced greater CES reported a longer length of time since their last doctor's visit B(SE) = .04(.02), p < .05. Experienced HIV stigma was not significantly associated with viral load results. However, social support significantly moderated the relationship between experienced stigma and viral load results. At higher levels of social support, those who experienced lower levels of stigma were more likely to report an undetectable viral load than those who had higher levels of stigma, B(SE) = - .13(.03), p < .001. Finally, both RAR and social support moderated the relationship between CES and viral load results. Those who reported higher levels of RAR B(SE) = - .07(.02), p < .001, and social support, B(SE) = - .02(.01), p < .05, also reported having an undetectable viral load at most recent HIV care visit. CES was not significantly related to reporting an undetectable viral load (p = .61). CONCLUSIONS: Enrolled PLWH already have some level of resilience which plays an important protective role within the context of the HIV care continuum up to a certain extent. Interventions to enhance the RAR and social support components may be useful especially among MSM and persons who have been living with HIV for a shorter period of time.

ABSTRACT

The various forms of HIV-related stigma continue to serve as major barriers to HIV care and treatment among men who have sex with men (MSM). The study of resilience within the context of HIV-related stigma among MSM living with HIV represents a promising area of research to inform the development of future HIV interventions for this population. We examined resilience within the context of HIV related stigma among MSM living with HIV in Louisiana with a particular interest in how resilience may be more relevant for Black MSM. We utilized Pearson's correlations and layered chi-square non-parametric tests to examine associations and racial differences in resilience, four HIV-related stigma measures/consequences (i.e., anticipated, internalized, enacted, and consequences of enacted HIV stigma), and HIV care outcomes (i.e., length of time since last HIV care visit, time since last HIV lab result, most recent HIV viral load result) among 110 MSM living with HIV in Louisiana who participated in the Louisiana HIV Stigma Index Project. The majority of MSM participants were Black (75%), lived in New Orleans (52%), and reported limited education (52%) and income (76%). MSM who reported higher levels of enacted HIV stigma, consequences of enacted HIV stigma, and internalized HIV stigma reported poorer HIV care outcomes. Both internalized and anticipated HIV stigma significantly negatively impacted Black MSM perceptions of their overall health compared with White MSM. Compared with White MSM, Black MSM who reported greater consequences of enacted HIV stigma had poorer HIV care outcomes. Resilience was associated with positive HIV care outcomes for both Black and White MSM. However, having higher levels of resilience may have been more protective for Black MSM such that higher levels of resilience were associated with less time since last HIV care visit for Black MSM than for White MSM. The current study provides preliminary information on the potential positive relationship between resilience and HIV care outcomes among MSM, particularly Black MSM. However, these findings need to be confirmed among a more representative sample of Black and White MSM in Louisiana.

ABSTRACT

Durable viral suppression (DVS) is needed to reduce HIV transmission risk and prevent new HIV infections. We examined changes in viral suppression and correlates of DVS among 97 criminal justice-involved (CJI) Black men living with HIV in Louisiana enrolled in a linkage, re-engagement, and retention in care intervention. Most participants (75%) were Black men who have sex with men. Forty-four percent (44%) were virally suppressed at baseline and only 20% had achieved DVS over a 12-month period. Multinomial logistic regression analyses showed that compared with DVS participants, those with no viral suppression (NVS) and some viral suppression (SVS) were more likely to have lived with HIV for a longer period of time and were less likely to be adherent at baseline. Medication adherence was critical for DVS among this sample of CJI Black men living with HIV who represent a high priority population for HIV care and treatment interventions.

ABSTRACT

BACKGROUND: We describe the background, rationale, intervention components, and formative results of a demonstration project aimed to ameliorate five socio-structural barriers to HIV services for young Black men aged 18-29 living with and at risk for HIV in Louisiana. METHODS: The interventions and activities consisted of (1) five person-centered approaches to enhance linkage to HIV services and improve socio-economic outcomes; (2) the implementation of systematic mystery shopping tests to document instances of housing discrimination; (3) the development and implementation of a multi-prong communications campaign to increase knowledge about the signs of housing discrimination and community resources among young Black men who have sex with men (YBMSM); (4) the integration of HIV/STI services and lesbian, gay, bisexual, and trans (LGBT)-inclusive events on Historically Black Colleges and Universities (HBCUs); and (5) the development of a safe space for YBMSM. A multi-method approach was used to evaluate the outcomes of the different interventions. RESULTS: The majority (62%) of participants living with HIV were linked to HIV care and 49% had achieved viral suppression. More than 40% of participants were employed during the project. Thirty-seven percent (37%) of the mystery shopping tests showed definite or possible signs of housing discrimination. The housing campaign's duration was limited with unknown long-term impact among YBMSM. Fifteen cases of syphilis were identified during two HBCU events. A safe space was specifically created for YBMSM at a community-based organization. CONCLUSION: Multi-component holistic health interventions are needed to improve HIV outcomes and curb the high HIV rates among young Black men, particularly YBMSM in the United States and the Deep South.

ABSTRACT

This article was migrated. The article was marked as recommended. Program theories have not been extensively used in evaluating faculty development programs in medical education. Ample evidence shows that a well-formulated program theory plays a pivotal role in program implementation and evaluation. Program theory links activities and expected outcomes using a logical process showing how they lead to long-term goals. It also develops appropriate metrics or indicators for assessing if those outcomes and activities really occurred. In this study, FAIMER's theory of change was adopted as a framework for evaluation. Survey data from FAIMER Fellows was used to assess the effectiveness of FAIMER's faculty development program in meeting the goal of improving health professions education. We used structural equation modeling to examine the association among outcomes mapped out in our theory of change and their association with improving field of health professions education. The study results indicated that FAIMER's faculty development program appeared to have positively influenced advancement of multiple facets of health professions education as envisaged in our theory of change. Using a theoretical framework for evaluating a program helped us identify the specific areas of outcomes that need to be strengthened for program improvement as well as provided us with a data-driven evaluation framework to measure program progress.

ABSTRACT

We explored the correlates of linkage to HIV medical care and barriers to HIV care among PLWH in Louisiana. Of the 998 participants enrolled, 85.8% were successfully linked to HIV care within 3 months. The majority of participants were male (66.2%), African American (81.6%), and had limited education (74.4%). Approximately 22% of participants were Black gay and bisexual men. The most common reported barrier to care was lack of transportation (27.1%). Multivariable analysis revealed that compared with Black gay and bisexual men, White gay and bisexual men were significantly more likely to be linked to HIV care (adjusted prevalence ratio, aPR 1.08, 95% CI 1.02-1.13). Additionally, participants reporting moderate to high levels of stigma at intake (p < 0.05) were significantly more likely to be linked to HIV care compared with those reporting low or no stigma at enrollment. Study findings highlight the continued importance of client-centered interventions and multi-sector collaborations to link PLWH to HIV medical care.

ABSTRACT

BACKGROUND: The relationship between mental health status and smoking is complicated and often confounded by bi-directionality, yet most research on this relationship assumes exogeneity. OBJECTIVES: The goal of this article is to implement an instrumental variable approach to (1) test the exogeneity assumption and (2) report on the association between mental health status and smoking post-disaster. METHODS: This analysis utilizes the 2006 and 2007 Louisiana Behavioral Risk Factor Surveillance Survey to examine the link between mental distress and smoking in areas affected by Hurricanes Katrina and Rita. Residence in a hurricane-affected parish (county) was used as an instrumental variable for mental distress. RESULTS: Just over 22% of the sample resided in a hurricane-affected parish. Residents of hurricane-affected parishes were significantly more likely to report occasional and frequent mental distress. Residence in a hurricane-affected parish was not significantly associated with smoking status. With residence established as a salient instrumental variable for mental distress, the exogeneity assumption was tested and confirmed in this sample. A dose-response relationship existed between mental distress and smoking, with smoking prevalence increasing directly (and non-linearly) with mental distress. CONCLUSIONS: In this sample, the relationship between mental distress and smoking status was exogenous and followed a dose-response relationship, suggesting that the disasters did not result in an uptake of smoking initiation, but that the higher amounts of mental distress may lead to increased use among smokers. The findings suggest that tobacco control programs should devise unique strategies to address mentally distressed populations.

ABSTRACT

txt4health is an innovative, 14-week, interactive, population-based mobile health program for individuals at risk of type 2 diabetes, developed under the Beacon Community Program in the Greater New Orleans, La., area. A comprehensive social marketing campaign sought to enroll hard-to-reach, at-risk populations using a combination of mass media and face-to-face engagement in faith-based and retail environments. Little is known about the effectiveness of social marketing for mobile technology application in the general population. A systematic evaluation of the campaign identified successes and barriers to implementing a population-based mobile health program. Face-to-face engagement helped increase program enrollment after the initial launch; otherwise, enrollment leveled off over time. Results show positive trends in reaching target populations and in the use of mobile phones to record personal health information and set goals for reducing the risk of type 2 diabetes. The lessons from the txt4health campaign can help inform the development and programmatic strategies to provide a person-level intervention using a population-level approach for individuals at risk for diabetes as well as aid in chronic disease management.

ABSTRACT

OBJECTIVE: Persons with schizophrenia often receive suboptimal physical health care, but the reasons are poorly understood. Vignettes have been used to examine how a patient's race, gender, or physical health influences a provider's practice; in this study, we used vignettes to examine the effect of a mental health diagnosis (schizophrenia) on providers' clinical expectations and decision making regarding physical health care. METHOD: A cross-sectional survey was administered from August 2011 to April 2012 to 275 primary care and mental health providers in 5 US Department of Veterans Affairs medical centers. Vignettes described identical scenarios for patients with and without schizophrenia. The survey assessed providers' clinical expectations of patients (adherence, competence, ability to read and understand health education materials) and practice behaviors (referrals to weight reduction, pain management, and sleep study). RESULTS: Clinicians expected persons with schizophrenia would be less adherent to treatment (P = .04), less able to read and understand educational materials (P = .03), and less capable of managing their health and personal affairs (P < .01). Providers were less likely to refer a patient with schizophrenia to a weight-reduction program (P = .03). Other types of referral decisions (for pain management and sleep study) were not influenced by a schizophrenia diagnosis. CONCLUSIONS: For both mental health and primary care providers, a history of schizophrenia was found to negatively affect provider expectations of patients' adherence to treatment, ability to understand educational materials, and capacity to manage their treatment and financial affairs as well as some treatment decisions, such as referral to a weight-reduction program.

ABSTRACT

OBJECTIVE: This study compared the attitudes of mental health and primary care providers toward persons with schizophrenia at 5 Veterans Affairs (VA) facilities. METHOD: This study utilized a cross-sectional anonymous survey, including clinical vignettes describing identical patient scenarios for a hypothetical patient with and without schizophrenia, to examine the differences in attitudes of primary care and mental health providers. The survey was distributed in 3 waves from August 2011 to April 2012. Participants included 351 VA providers from 5 VA medical centers, including 205 mental health providers (psychiatrists, psychologists, and mental health nurses) and 146 primary care providers (nurses and physicians). Providers' attitudes were assessed on 3 domains, including social distance, stereotyping, and attribution of mental illness. RESULTS: Primary care providers had significantly more negative attitudes toward the vignette patient with schizophrenia compared with the patient without schizophrenia on 2 of 3 attitude measures (stereotyping and attribution of mental illness); however, this difference was not observed for mental health providers on the 2 measures. Conclusions and Implication for Practice: Primary care providers' negative attitudes toward individuals with schizophrenia represent a potential target for interventions to reduce disparities in care for individuals with schizophrenia.

ABSTRACT

INTRODUCTION: Quality incentive programs, such as Meaningful Use, operate under the assumption that clinical quality measures can be reliably extracted from EHRs. Safety Net providers, particularly Federally Qualified Health Centers and Look-Alikes, tend to be high adopters of EHRs; however, recent reports have shown that only about 9% of FQHCs and Look-Alikes were demonstrating meaningful use as of 2013. Our experience working with the Crescent City Beacon Community (CCBC) found that many health centers relied on chart audits to report quality measures as opposed to electronically generating reports directly from their EHRs due to distrust in the data. This paper describes a step-by-step process for improving the reliability of data extracted from EHRs to increase reliability of quality measure reports, to support quality improvement, and to achieve alignment with national clinical quality reporting requirements. BACKGROUND: Lack of standardization in data capture and reporting within EHRs drives distrust in EHR-reported data. Practices or communities attempting to achieve standardization may look to CCBC's experience for guidance on where to start and the level of resources required in order to execute a data standardization project. During the time of this data standardization project, CCBC was launching an HIE. Lack of trust in EHR data was a driver for distrust in the HIE data. METHODS: We present a case study where a five-step process was used to harmonize measures, reduce data errors, and increase trust in EHR clinical outcomes reports among a community of Safety Net providers using a common EHR. Primary outcomes were the incidence of reporting errors and the potential effect of error types on quality measure percentages. The activities and level of resources required to achieve these results were also documented by the CCBC program. FINDINGS: Implementation of a community-wide data reporting project resulted in measure harmonization, reduced reporting burden, and error reduction in EHR-generated clinical outcomes reporting across participating clinics over a nine-month period. Increased accuracy of clinical outcomes reports provided physicians and clinical care teams with better information to guide their decision-making around quality improvement planning. DISCUSSION: A number of challenges exist to achieving reliable population level quality reporting from EHRs at the practice, vendor, and community levels. Our experience demonstrates that quality measure reporting from EHRs is not a straightforward process, and it requires time and close collaboration between clinics and vendors to improve reliability of reports. Our experience found that practices valued the opportunity and step-wise process to validate their data locally (out of their EHRs) prior to reporting out of the HIE. CONCLUSION AND NEXT STEPS: Communities can achieve higher levels of confidence in quality measure reporting at the population level by establishing collaborative user groups that work with EHR vendors as partners and use technical assistance to build relationships and trust in EHR-generated reports. While this paper describes the first phase of our work around improving standardization and reliability of EHR reports, vendors should continue to explore modifications for improving data capture (at the front-end) via standardized data entry templates.

ABSTRACT

Successful recall Ab responses require recruitment of quiescent memory B cells to secondary lymphoid organs. However, the cellular dynamics of memory cells responding to local antigenic challenge at lymphoid sites distal from the initial Ag encounter are not well understood. We show in this study that memory B cells generated following s.c. immunization in one footpad generate secondary responses to soluble Ag given i.p. but not to Ag given s.c. in the contralateral footpad unless LPS is coadministered. Memory B cells do not express CD62L, and CD62L(-ve) cells cannot enter lymph nodes unless LPS-mediated inflammation is induced there. Functional TLR4 is required on the B cells, as well as on non-B cells, in the lymph node to achieve full recruitment. Furthermore, splenectomized mice fail to respond to such inflammatory s.c. challenge in contralateral footpads, unlike lymphadenectomized mice lacking the original draining lymph nodes. Splenectomized mice also fail to respond to i.p. challenge with soluble Ag. Together, these data indicate that, unlike the central memory pool of T cells, which circulates through resting lymph nodes, the majority of long-lived memory B cells are spleen resident and require inflammatory signals for mounting recall responses at distal challenge sites.

ABSTRACT

Cystatin, a natural cysteine protease inhibitor, has strong antileishmanial activity, which is due to its potential to induce nitric oxide (NO) generation from macrophages. Cysteine protease-inhibitory activity and NO-up-regulatory activity correspond to different regions, as revealed by the dissection of cystatin cDNA into nonoverlapping fragments. By using synthetic overlapping peptides, the NO-up-regulatory activity was found to be confined to a 10-mer sequence. In addition to having reasonable inhibitory effects on amastigote multiplication within macrophages (50% inhibitory concentration, 5.2 microg/ml), 97 and 93% suppression, respectively, of liver and spleen parasite burdens was achieved with the 10-mer peptide at a dose of 0.5 mg/kg of body weight/day, given consecutively for 4 days along with a suboptimal dose of gamma interferon in a 45-day mouse model of visceral leishmaniasis. Peptide treatment modulated the levels of cytokine secretion by infected splenocytes, with increased levels of interleukin-12 and tumor necrosis factor alpha and increased inducible NO synthase production, and also resulted in resistance to reinfection. The generation of a natural peptide from cystatin with robust immunomodulatory potential may therefore provide a promising therapeutic agent for macrophage-associated diseases.

ABSTRACT

OBJECTIVE: The purpose of this study was to examine the feelings of disadvantaged patients about and experiences of treatment for anxiety disorders in primary care settings. METHODS: The patients had participated in the Collaborative Care for Anxiety and Panic study, which tested the effectiveness of an intervention to help primary care providers treat panic disorder. The treatment comprised cognitive behavioral therapy (CBT) combined with pharmacotherapy administered by primary care physicians with the expert advice of a psychiatrist. Post hoc semistructured interviews were conducted with 21 intervention participants who were classified according to adherence or nonadherence to treatment. The interview focused on reactions to CBT; reactions to the different features of the intervention, such as therapy sessions, demonstration videotapes, exercises, and a workbook; and comfort with the therapist. Two members of the research team independently coded, analyzed, and interpreted the data. RESULTS: Three themes emerged: information was empowering and reduced the sense of isolation experienced by participants, participants engaged in a dynamic and iterative personalized assessment of the intervention, and barriers to adherence were predominantly logistical. CONCLUSIONS: Results indicate that the extent to which patients chose to remain in treatment and follow treatment recommendations was rarely an all-or-nothing phenomenon. In a disadvantaged population such decisions seem to be influenced by the beliefs of the patient about what will and will not be effective in his or her individual case, an ongoing self-assessment of well-being, and the logistical barriers that come into play.

ABSTRACT

A neuronal type Ca2+ stimulated nitric oxide synthase was earlier reported by us to be present in the protozoan parasite Leishmania donovani. As part of nitric oxide-cyclic GMP transduction signaling operative in higher eukaryotes and involved in the long-term potentiation, a soluble guanylyl cyclase has also been detected in this lower eukaryote. However, detailed biochemical characterization revealed the enzyme to be Ca2+ modulated and unstimulated by nitric oxide donors as opposed to higher eukaryotes. The possible role of intracellular Ca2+ level in the regulation of guanylyl cyclase activity as well as L. donovani infectivity was explored by measuring the intracellular survival of the parasites in mammalian macrophages after treatments, which decrease or elevate the intracellular Ca2+. Parasites loaded with intracellular Ca2+ chelators displayed significantly decreased infectivity and cyclic GMP level. In contrast, pretreatment with Ca2+ ionophores, which elevated Ca2+ levels in L. donovani, significantly enhanced the cyclic GMP level as well as the infectivity of the parasites. Moreover, treatment with selective inhibitors of soluble guanylyl cyclase also reduced infectivity, even in cases of calcium ionophore-treated parasites. The gene encoding the soluble guanylyl cyclase was cloned, sequenced and over expressed in bacterial system. The recombinant protein showed enzyme characteristics similar to that obtained in L. donovani promastigote cytosol. Together these results suggest a possible link between guanylyl cyclase, intracellular Ca2+ content and parasite infectivity.

ABSTRACT

PURPOSE: This study was undertaken to determine whether the Adult Identity Mentoring (AIM) project successfully promotes abstinence, delays initiation of sex, and decreases intention to engage in sex. METHODS: Twenty middle school classes of African-American seventh graders were randomly assigned to receive either the AIM intervention or a standard health education control curriculum. The AIM is a 10-session curriculum based on the theory of possible selves. Class exercises encourage students to articulate a possible future self-identity and to develop self-promotion skills. Surveys about sexual activity were conducted before the intervention, 19 weeks after baseline, and again at 1 year after the intervention. RESULTS: Hierarchical logistic regression analyses showed significant effects for the intervention on sexual intentions, abstinence, and a trend toward fewer virgins initiating intercourse for the first time, 19 weeks after baseline. Specifically, students who received the intervention showed decreased intention to engage in sex and increased abstinence compared with students not receiving the intervention. Effects for 1-year follow-up, with smaller sample size, showed only that AIM male participants maintained the significant abstinence effect. CONCLUSIONS: A new intervention, AIM was evaluated among African-American seventh graders. This program, by focusing students on positive future selves, effectively modified sexual risk without directly providing instruction on sexually explicit topics.

ABSTRACT

Even when interventions are shown to be both clinically effective and cost-effective within a system of care, they are rarely sustained beyond the period of external funding. The reason may be that these interventions are often developed and introduced in a "top-down" manner, with little input from frontline clinicians. The purpose of this article is to describe a "bottom-up" approach in which services researchers assist frontline clinicians in testing interventions that clinicians themselves have devised. This approach is explored in the clinical partnership program developed by the Veterans Healthcare Administration's South Central Mental Illness Research, Education, and Clinical Center. The program is expected to expand the evaluation and research capacity of clinicians, enhance the collaborative skills of services researchers, and result in interventions that are more likely to be sustained over time.

ABSTRACT

This study examined the perceived public stigma for alcohol use and treatment among a sample of 733 at-risk drinkers living in the South. Substantial levels of perceived stigma were reported for the community's judgment about at-risk drinking (86.1%), community's judgment about seeking primary care treatment for alcohol disorders (48.9%), community's judgment about seeking specialty treatment (56.3%), and primary care providers' judgment about their patients who were at-risk drinkers (35.7%). Similarly, respondents perceived a substantial lack of privacy associated with primary care treatment (42.0%) and specialty treatment (45.2%). African Americans were more likely to perceive a lack of treatment privacy but they were less likely to perceive community judgment about seeking specialty treatment. Those with greater social network contact intensity were more likely to perceive community judgment about at-risk drinking and more likely to perceive a lack of treatment privacy. Rural at-risk drinkers were more likely to perceive a lack of privacy in primary care.

ABSTRACT

Early sexual activity of adolescents is associated with increased risk of teenage pregnancy, sexually transmitted infections including HIV, and higher maternal/perinatal morbidity and mortality. HIV and adolescent pregnancy are among the most serious public health problems in Jamaica. The objective of this study was to identify the potential predictors of adolescent sexual activity in Jamaica. A cross-sectional survey was conducted among 788 students 13-19 years of age in Jamaica. A questionnaire containing items on socio-demographic characteristics such as age and gender, and scales on adolescent values about sexual activity, self-efficacy for abstinence, parental love, and depression were administered to adolescents at secondary schools in the parish of Hanover. Reliability analysis of the scales, descriptive statistics, and logistic regression to determine predictors of sexual activity were conducted. Approximately 62% of adolescents who responded reported previous sexual intercourse and 38% reported never having had sex. The mean age for sexual debut was 13.6 years. Logistic regression revealed delay values (values towards delaying sexual activity) as protective (OR=0.16, CI=0.09-0.26) against involvement in sexual activity. Risk factors for sexual activity included being older (OR=1.9, CI=1.50-2.50), being male (OR=2.26, CI=1.39-3.68) and having grown-up values (OR=1.49, CI=1.05-2.12). Contrary to expectations, having higher self-efficacy skills was predictive (OR=1.47, CI=1.05-2.05) of adolescent sexual involvement. Analyses by gender revealed that delay and grownup values predicted male sexual activity, while self-efficacy, paternal love and delay values predicted female behavior. These findings show the importance of age, gender, self-efficacy, delay and grown-up values in predicting sexual activity in adolescents and indicate the need for gender-specific interventions for Jamaican adolescents.
