Changes in Adherence and Viral Load Suppression Among People with HIV in Manila: Outcomes of the Philippines Connect for Life Study

The Philippines HIV epidemic is among the fastest growing globally. Infections among men who have sex with men are rising at an alarming rate, necessitating targeted evidence-based interventions to retain people living with HIV in care, support adherence, and reach viral suppression. We conducted a 48-week prospective cohort study of 462 participants in which we provided a mobile health (mHealth) adherence support intervention using the Connect for Life platform. We observed an improvement in adherence, with the proportion of participants taking more than 95% of their antiretroviral therapy (ART) doses increasing from 78.6% at baseline to 90.3% at 48 weeks. Among treatment experienced participants, adherence improved significantly (McNemar's test = 21.88, P < 0.001). Viral load suppression did not change, with 92.6% suppression at baseline and 92.0% at 48 weeks. Illicit drug use was associated with reduced adherence (aOR = 0.56, 95%CI 0.31-1.00, P = 0.05) and being on second-line therapy was associated with poor viral load suppression (aOR = 0.33, 95%CI 0.14-0.78, P = 0.01). Quality of life improved following ART initiation, from a mean of 84.6 points (of a possible 120) at baseline to 91.01 at 48 weeks. Due to technical issues, fidelity to the intended intervention was low, with 22.1% (102/462) of participants receiving any voice calls and most others receiving a scaled-back SMS intervention. The mHealth intervention did not have any observed effect on adherence or on viral load suppression. While evidence of effectiveness of mHealth adherence interventions is mixed, these platforms should continue to be explored as part of differentiated treatment support services.

Prevalence of hypertension and high-normal blood pressure among young adults in Zimbabwe: findings from a large, cross-sectional population-based survey

BACKGROUND

Hypertension is the greatest driver of cardiovascular mortality and onset might be in youth. We aimed to investigate the prevalence of and risk factors for elevated blood pressure (hypertension ≥140 mm Hg systolic, ≥90 mm Hg diastolic, or both) and high-normal blood pressure (130-139 mm Hg systolic, 85-89 mm Hg diastolic, or both) among youth in Zimbabwe.

METHODS

A population-based, cross-sectional survey of randomly sampled youth aged 18-24 years from 24 urban and peri-urban communities in three provinces (Harare, Bulawayo, and Mashonaland East) in Zimbabwe was conducted between Oct 4, 2021, and June 2, 2022. Standardised questionnaires were used by research assistants to collect sociodemographic, behavioural, and clinical data. Height, bodyweight, and blood pressure were recorded. Three seated blood pressure measurements were taken at standardised timepoints during participant interview using a digital sphygmomanometer and cuffs sized on mid-upper arm circumference. The association of potential risk factors with elevated blood pressure was examined using multivariable logistic regression.

FINDINGS

17 682 (94·4%) of 18 729 eligible participants were recruited, 17 637 (99·7%) of whom had complete data, and 16 883 (95·7%) of whom were included in the final study sample after excluding 754 (4·3%) pregnant women. The median age was 20 years (IQR 19-22), 9973 (59·1%) participants were female, and 6910 (40·9%) were male. The prevalence of hypertension was 7·4% (95% CI 7·0-7·8) and high-normal blood pressure was 12·2% (11·7-12·7). Overall, prevalence of hypertension was higher in men (8·7% [95% CI 8·2-9·6]) than in women (6·6% [6·0-6·9]), but with age increased to similar levels (at age 18 years 7·3% [6·2-8·6] and 4·3% [3·5-5·2]; at age 23-24 years 10·9% [9·3-12·6] and 9·5% [8·4-10·7] in men and women, respectively). After adjusting for factors associated with hypertension in the crude analysis, hypertension was associated with male sex (adjusted odds ratio 1·53 [95% CI 1·36-1·74]), increasing age (age 19-20 years 1·20 [1·00-1·44]; age 21-22 years 1·45 [1·20-1·75]; age 23-24 years 1·90 [1·57-2·30], vs age 18 years), and BMI of 30·0 kg/m2 or more (1·94 [1·53-2·47] vs 18·5-24·9 kg/m2). A BMI of 18·5 kg/m2 or less (0·79 [0·63-0·98] vs 18·5-24·9 kg/m2) and living with HIV (0·71 [0·55-0·92]) were associated with lower odds of hypertension.

INTERPRETATION

Prevalence of elevated blood pressure is high among urban and peri-urban youth in Zimbabwe and increases rapidly with age. Further research is needed to understand drivers of blood pressure elevation and the extent of target organ damage in youth in Zimbabwe and similar sub-Saharan African settings, to guide implementation of prevention and management strategies.

Misconceptions, Misinformation, and Misperceptions: A Case for Removing the "Mis-" When Discussing Contraceptive Beliefs

Beliefs about contraception are commonly conceptualized as playing an important role in contraceptive decision-making. Interventions designed to address beliefs typically include counseling to dispel any "myths" or "misconceptions." These interventions currently show little evidence for impact in reducing beliefs. This commentary delves into the problems associated with using implicitly negative terminology to refer to contraceptive beliefs, which come laden with assumptions as to their validity. By conceptualizing women as getting it wrong or their beliefs as invalid, it sets the scene for dubious treatment of women's concerns and hampers the design of fruitful interventions to address them. To replace the multitude of terms used, we suggest using "belief" going forward to maintain value-free curiosity and remove any implicit assumptions about the origin or validity of a belief. We provide recommendations for measuring beliefs to help researchers understand the drivers and impacts of the belief they are measuring. Finally, we discuss implications for intervention design once different types of belief are better understood. We argue that tailored interventions by belief type would help address the root causes of beliefs and better meet women's broader contraceptive needs, such as the need for contraceptive autonomy and satisfaction.

Delivering an mHealth Adherence Support Intervention for Patients With HIV: Mixed Methods Process Evaluation of the Philippines Connect for Life Study

Background

The Philippines HIV epidemic is one of the fastest growing epidemics globally, and infections among men who have sex with men are increasing at an alarming rate. Connect for Life Philippines is a mobile health (mHealth) intervention that supports antiretroviral therapy (ART) adherence in this key population through individualized voice calls and SMS text messages.

Objective

The objective of this process evaluation is to assess the intervention reach, dose delivered and received, fidelity, and acceptability and to describe contextual factors affecting the implementation of an mHealth adherence support intervention for patients on ART in a clinic in Metro Manila, Philippines.

Methods

A mixed methods process evaluation approach was used in an observational cohort study. Quantitative data sources for the process evaluation were call and SMS text message logs obtained from the mHealth platform and questionnaires collected at 12-, 24-, and 48-week study visits. Qualitative data were collected from process reports and through a series of focus group discussions conducted with a subset of participants during the intervention development phase, after an initial 8-week pilot phase, and at the end of the study.

Results

The 462 study participants received 31,095 interactive voice calls and 8234 SMS text messages during the study. Owing to technical issues, intervention fidelity was low, with only 22.1% (102/462) of the participants receiving reminders via voice calls and others (360/462, 77.9%) receiving only SMS text messages during the intervention. After 48 weeks in the study, 63.5% (293/462) of the participants reported that they would be quite likely or very likely to recommend the program to a friend, and 53.8% (249/462) of the participants reported that they benefited quite a bit or very much from the intervention. Participants who were on ART for <6 months at the beginning of the study and those who received the daily or weekly pill reminders were more likely to report that they benefited from the intervention (P=.02 and P=.01, respectively).

Conclusions

The Connect for Life intervention had high participant satisfaction and acceptability, especially among those who received high dose of the intervention. However, poor reliability of local telecommunication networks had a large impact on the intervention’s usability, fidelity, and dose received.

Interactive Mobile Phone HIV Adherence Support for Men Who Have Sex With Men in the Philippines Connect for Life Study: Mixed Methods Approach to Intervention Development and Pilot Testing

BACKGROUND

The HIV epidemic in the Philippines is one of the fastest growing epidemics globally, and infections among men who have sex with men are rising at an alarming rate. The World Health Organization recommends the use of mobile health (mHealth) technologies to engage patients in care and ensure high levels of adherence to antiretroviral therapy (ART). Existing mHealth interventions can be adapted and tailored to the context and population served.

OBJECTIVE

This study aims to create a locally tailored intervention using a mobile phone platform to support treatment adherence for HIV patients on ART in the Philippines.

METHODS

A mixed methods approach guided by the Behavior Change Wheel framework was used to adapt an existing mHealth adherence support platform for the local setting and target population. A literature review, retrospective clinical record review, and focus group discussions with patients were conducted to understand the drivers of ART adherence and tailor the intervention accordingly. The resulting intervention was pilot-tested for 8 weeks, followed by focus group discussions with patients who received the intervention to assess the acceptability of the design.

RESULTS

Key issues contributing to nonadherence included side effects, lack of behavioral skills for pill taking, social support, mental health, and substance use. Patients identified mHealth as an acceptable mode of intervention delivery and wanted mHealth services to be highly personalizable. The study team, clinicians, and software developers integrated these findings into the intervention, which included a menu of services as follows: pill reminders, health tips, adherence feedback, appointment reminders, and symptom reporting. During the pilot phase, technical issues in the interactive voice response system (IVRS) were identified and addressed. Patients who participated in the pilot phase expressed a preference for SMS text messaging over the IVRS. Patients responded positively to the appointment reminders and health tips, whereas patient feedback on daily and weekly pill reminders and adherence feedback was mixed.

CONCLUSIONS

The mobile phone-based SMS text messaging and IVRS intervention was acceptable to men who have sex with men in Manila, the Philippines, and qualitative analysis suggested that the intervention helped promote ART adherence and appointment attendance.

What do adolescents value most and is this affected by HIV status? Aspirations and self-perceptions from a large cohort study in South Africa

Hundreds of millions of adolescents across Africa face challenges in many areas of their lives, including elevated risk of HIV exposure and acquisition. Understanding the aspirations and self-perceptions of adolescents could play an important role in better targeting effective investments to break the cycle of adversity for adolescents and into their adulthood. Aiming to understand what adolescents value most for themselves and their future, we analysed and summarised cross-sectional data on the aspirations and self-perceptions of 1519 adolescents living in South Africa, overall and by HIV status. Outcomes were coded from participant responses to two open-ended questions: 'What job do you want to do when you grow up?' and 'What are you most proud of about yourself?'. Associations with HIV status were then evaluated using multivariable logistic regression adjusting for six sociodemographic factors measured from the same cohort. The sample had a mean age of 14 years, 55% were female, and 70% were living with HIV. The five most common job aspirations were: 'Health and Medical Science Professionals' (28%), 'Law Enforcement and Public Safety Professionals' (14%), 'Social Work Associate Professionals' (12%), 'Legal Professionals' (9%), and 'Education Institutions Teaching Professionals' (6%). The top five themes for what adolescents were most proud of about themselves were 'School performance' (22%), 'Outward appearance' (15%), 'Sports skills' (12%), 'Personality' (11%), and 'Behaviour at home/with elders' (7%). Adjusted analysis showed no evidence that HIV status was associated with important differences in aspirations or self-perceptions. In conclusion, adolescents facing high levels of adversity in South Africa hold high value for their education and aspirations for their futures. Policies and initiatives should focus on meeting these aspirations as vehicles for development, independent of their HIV status. Therefore, more needs to be done to not just help adolescents survive but thrive into adulthood.

Engagement with young people as partners in health research: Four case studies from Sub-Saharan Africa

OBJECTIVES

Existing health services for young people (YP)(10-24 years), which are predominantly designed for but not with young people, often do not meet YP's needs. The 2018 Global Consensus Statement on meaningful adolescent and youth engagement affirms that YP have a fundamental right to actively and meaningfully engage in all matters that affect their lives. We present four case studies from three countries in sub-Saharan Africa as practical examples of the engagement of young people as partners in health research. We critically reflect on best practices to inform and guide the increasing adoption of collaborative approaches.

METHODS

We developed a narrative summary of each case study through review of study documentation and discussions with research staff and young people. A youth engagement framework was used to describe partnership activities according to the following dimensions: purpose, process, positioning, perspective, power relations, place and protection. We reflected on innovative practices used, overall level of participation achieved and strategies to address ethical, logistical and/or financial barriers.

RESULTS

In all case studies, we found evidence of engagement activities that aligned with the Global Consensus Statement on Meaningful Youth Engagement. However, access to participation was often uneven and despite efforts, marginalised young people continue to have insufficient opportunities to engage. Furthermore, although young people had some opportunity to influence the research methods, many of the key design decisions had been determined prior to their involvement. In our case studies, researchers had built in insufficient opportunities to evaluate the level and impact of youth engagement.

CONCLUSIONS

We therefore recommend early involvement of young people in the research process so that they can contribute to setting the research agenda, the design of planned studies and thus increase the scope of their engagement from the beginning. Youth engagement activities need to be evaluated from the perspective of all stakeholders including young people themselves with a focus on opportunities to engage, the level of engagement achieved and impact of engagement. From the beginning, researchers should provide space for learning, and involve young people in encouraging critical reflection of what does not yet work, as well as what does, to enable improvements.

Designing Routine Health Checkups for Adolescents in Zimbabwe

PURPOSE

The absence of routine health check-ups during adolescence in low- and middle-income countries is a missed opportunity for prevention, early identification, and treatment of health issues, and health promotion. We aimed to codesign the content and delivery for routine adolescent health checkups in Zimbabwe, with adolescents and key adults in their lives.

METHODS

We held participatory workshops with adolescents (16 workshops; 96 adolescents) and parents (8 workshops; 95 parents), and in-depth interviews with key informants including policymakers, programmers, and healthcare workers (n = 25). Analysis was iterative and the design of the checkups was refined based on participant preferences, document review of burden of disease data, and feasibility considerations.

RESULTS

Participants overwhelmingly supported the introduction of routine health checkups. Reported facilitators to attendance included free cost and desire to know one's health status. Barriers included tendencies for health service seeking only when ill, fear of diagnosis and judgment, and religious beliefs. Delivery preferences were by nonjudgmental medical professionals, in a youth friendly environment, and accompanied by youth engagement activities. Preferred location was schools for younger adolescents (10-14 years), and community settings for older adolescents (15-19 years). Prioritized content included sexual health, oral health, mental health, hearing, eyesight, growth and nutrition, anemia, immunization, and deworming, based on health burden and participant preferences.

DISCUSSION

This study resulted in an outline design of two routine health checkups with stakeholders in Zimbabwe, in schools for young adolescents, and in community settings for older adolescents. Evidence of feasibility, effectiveness, and cost-effectiveness of such checkups is required.

Effectiveness and costs associated with a lay counselor-delivered, brief problem-solving mental health intervention for adolescents in urban, low-income schools in India: 12-month outcomes of a randomized controlled trial

BACKGROUND

Psychosocial interventions for adolescent mental health problems are effective, but evidence on their longer-term outcomes is scarce, especially in low-resource settings. We report on the 12-month sustained effectiveness and costs of scaling up a lay counselor-delivered, transdiagnostic problem-solving intervention for common adolescent mental health problems in low-income schools in New Delhi, India.

METHODS AND FINDINGS

Participants in the original trial were 250 school-going adolescents (mean [M] age = 15.61 years, standard deviation [SD] = 1.68), including 174 (69.6%) who identified as male. Participants were recruited from 6 government schools over a period of 4 months (August 20 to December 14, 2018) and were selected on the basis of elevated mental health symptoms and distress/functional impairment. A 2-arm, randomized controlled trial design was used to examine the effectiveness of a lay counselor-delivered, problem-solving intervention (4 to 5 sessions over 3 weeks) with supporting printed booklets (intervention arm) in comparison with problem solving delivered via printed booklets alone (control arm), at the original endpoints of 6 and 12 weeks. The protocol was modified, as per the recommendation of the Trial Steering Committee, to include a post hoc extension of the follow-up period to 12 months. Primary outcomes were adolescent-reported psychosocial problems (Youth Top Problems [YTP]) and mental health symptoms (Strengths and Difficulties Questionnaire [SDQ] Total Difficulties scale). Other self-reported outcomes included SDQ subscales, perceived stress, well-being, and remission. The sustained effects of the intervention were estimated at the 12-month endpoint and over 12 months (the latter assumed a constant effect across 3 follow-up points) using a linear mixed model for repeated measures and involving complete case analysis. Sensitivity analyses examined the effect of missing data using multiple imputations. Costs were estimated for delivering the intervention during the trial and from modeling a scale-up scenario, using a retrospective ingredients approach. Out of the 250 original trial participants, 176 (70.4%) adolescents participated in the 12-month follow-up assessment. One adverse event was identified during follow-up and deemed unrelated to the intervention. Evidence was found for intervention effects on both SDQ Total Difficulties and YTP at 12 months (YTP: adjusted mean difference [AMD] = -0.75, 95% confidence interval [CI] = -1.47, -0.03, p = 0.04; SDQ Total Difficulties: AMD = -1.73, 95% CI = -3.47, 0.02, p = 0.05), with stronger effects over 12 months (YTP: AMD = -0.98, 95% CI = -1.51, -0.45, p < 0.001; SDQ Total Difficulties: AMD = -1.23, 95% CI = -2.37, -0.09; p = 0.03). There was also evidence for intervention effects on internalizing symptoms, impairment, perceived stress, and well-being over 12 months. The intervention effect was stable for most outcomes on sensitivity analyses adjusting for missing data; however, for SDQ Total Difficulties and impairment, the effect was slightly attenuated. The per-student cost of delivering the intervention during the trial was $3 United States dollars (USD; or $158 USD per case) and for scaling up the intervention in the modeled scenario was $4 USD (or $23 USD per case). The scaling up cost accounted for 0.4% of the per-student school budget in New Delhi. The main limitations of the study's methodology were the lack of sample size calculations powered for 12-month follow-up and the absence of cost-effectiveness analyses using the primary outcomes.

CONCLUSIONS

In this study, we observed that a lay counselor-delivered, brief transdiagnostic problem-solving intervention had sustained effects on psychosocial problems and mental health symptoms over the 12-month follow-up period. Scaling up this resource-efficient intervention is an affordable policy goal for improving adolescents' access to mental health care in low-resource settings. The findings need to be interpreted with caution, as this study was a post hoc extension, and thus, the sample size calculations did not take into account the relatively high attrition rate observed during the long-term follow-up.

Risk factors affecting adherence to antiretroviral therapy among HIV patients in Manila, Philippines: a baseline cross-sectional analysis of the Philippines Connect for Life Study

Background The Philippines HIV epidemic is one of the fastest growing, globally. Infections among men who have sex with men (MSM) are rising at an alarming rate, necessitating targeted evidence-based interventions to reach epidemic control. Treatment as prevention is a key strategy to end AIDS, making it a priority to explore novel approaches to retain people living with HIV (PLHIV) in care, support adherence, and reach viral suppression.

METHODS

This cross-sectional analysis describes HIV-related risk behaviours and adherence to antiretroviral therapy (ART) in a population of HIV-positive patients at a clinic in Metro Manila, Philippines participating in the Philippines Connect for LifeTM cohort study.

RESULTS

Among 426 HIV-positive adults taking ART, 79% reported ≥95% adherence over the prior 30 days. Longer time on treatment was associated with reduced adherence to ART (adjusted odds ratio (AOR) = 0.87 per year, P = 0.027). Being in a serodiscordant relationship, in which the subject's primary partner was HIV negative, increased adherence (AOR = 3.19, P = 0.006). Inconsistent condom use (AOR = 0.50, P = 0.103) and injection drug use (AOR = 0.54, P = 0.090) are potentially associated with reduced adherence to ART. Patients used drugs and alcohol at significantly higher rates than the general population.?

CONCLUSIONS

The study found that patients in this setting require intervention to address treatment fatigue. Interventions to improve social support of PLHIV, as well as harm-reduction approaches for drug and alcohol use, could improve adherence in this population, strengthening the test-and-treat strategy to control the epidemic.

Mobile Phone Access and Implications for Digital Health Interventions Among Adolescents and Young Adults in Zimbabwe: Cross-Sectional Survey

BACKGROUND

Mobile phones may help young people (YP) access health information and support health service engagement. However, in low-income settings there is limited knowledge on YP's phone and internet access to inform the feasibility of implementing digital health interventions.

OBJECTIVE

We investigated access to information and communication technologies among adolescents and young adults in Zimbabwe.

METHODS

A cross-sectional population-based survey was conducted from October to December 2018 among YP aged 13-24 years in 5 communities in urban and peri-urban Harare and Mashonaland East, Zimbabwe. Consenting YP completed a self-completed tablet-based questionnaire on mobile phone ownership and use, and use of the internet. The primary outcome was the proportion who reported owning a mobile phone. Secondary outcomes included phone and internet access and use behavior, and ownership and use of other technological devices. Multivariable logistic regression was used to investigate factors associated with mobile phone ownership and with internet access, with adjustment for the one-stage cluster sampling design. A priori exploratory variables were age, sex, marital status, and urban/peri-urban residence.

RESULTS

A total of 634/719 (88.2%) eligible YP, mean age 18.0 years (SD 3.3) and 62.6% (397/634) females, participated. Of the YP interviewed, 62.6% (396/633; 95% CI 58.5-66.5) reported owning a phone and a further 4.3% (27/633) reported having access to a shared phone. Phone ownership increased with age: 27.0% (43/159) of 13-15-year olds, 61.0% (72/118) of 16-17-year olds, 71.5% (103/144) of 18-19-year olds, and 84.7% (171/202) of 20-24-year olds (odds ratio [OR] 1.4, 95% CI 1.3-1.5) per year increase. Ownership was similar among females and males: 61.0% (236/387; 95% CI 55.6-66.1) versus 64.8% (153/236; 95% CI 57.8-71.2), age-adjusted OR 0.7 (95% CI 0.5-1.1); higher in those with secondary level education compared to primary or no education: 67.1% (346/516; 95% CI 62.6-71.2) versus 26% (21/82; 95% CI 16.4-37.7), age-adjusted OR 2.3 (95% CI 1.1-4.8); and similar across other sociodemographic factors. YP reported that 85.3% (361/423) of phones, either owned or shared, were smartphones. Among phone owners, the most commonly used phone app was WhatsApp (71.2%, 282/396), and 16.4% (65/396) reported having ever used their phone to track their health. A total of 407/631 (64.5%; 95% CI 60.3-68.5) currently had access to the internet (used in last 3 months on any device) with access increasing with age (OR 1.2, 95% CI 1.2-1.3 per year increase). In age-adjusted analysis, internet access was higher among males, the unmarried, those with a higher level of education, phone owners, and those who had lived in the community for more than 1 year. The aspect of the internet that YP most disliked was unwanted sexual (29.2%, 136/465) and violent (13.1%, 61/465) content.

CONCLUSIONS

Mobile phone-based interventions may be feasible in this population; however, such interventions could increase inequity, especially if they require access to the internet. Internet-based interventions should consider potential risks for participants and incorporate skill-building sessions on safe internet and phone use.

Modern contraceptive use among unmarried girls aged 15-19 years in South Western Nigeria: results from a cross-sectional baseline survey for the Adolescent 360 (A360) impact evaluation

PURPOSE

Adolescents 360 (A360) is an initiative being rolled out across Nigeria with the aim of increasing voluntary modern contraception use among women aged 15 to 19 years. Using evaluation study baseline data, we identified sexuality, fertility and contraceptive use characteristics of young unmarried girls in South Western Nigeria.

METHODS

A cross-sectional baseline survey of unmarried girls aged 15 to 19 years was conducted in Ogun state, Nigeria in August 2017. A clustered sampling design was used. We identified determinants of modern contraceptive use in this subpopulation using logistic regression.

RESULTS

Of 12,024 women interviewed, 15.3% reported sexual intercourse in the past year. The majority of respondents (79.6%, 9525/11,967) had heard of contraception. 45.3% of sexually active respondents were using a modern contraceptive method. Of those using any method of contraception, male condoms (50.3%) were the most widely used modern method followed by the emergency contraceptive pill (16.7%). Following adjustment for socio-demographic characteristics, there was evidence that the use of modern contraception was positively associated with having never given birth, living in an urban area, current enrolment in education, high level of education, high socioeconomic status, exposure to information about contraception, perceived social support for contraception, and self-efficacy for contraception.

CONCLUSIONS

In South Western Nigeria, unmarried sexually active adolescent girls have relatively low levels of modern contraceptive use. Programmes should aim to increase access to modern contraception and to increase social support and acceptability of contraceptive use.

Clustering of health risk behaviors among adolescents in Kilifi, Kenya, a rural Sub-Saharan African setting

BACKGROUND

Adolescents tend to experience heightened vulnerability to risky and reckless behavior. Adolescents living in rural settings may often experience poverty and a host of risk factors which can increase their vulnerability to various forms of health risk behavior (HRB). Understanding HRB clustering and its underlying factors among adolescents is important for intervention planning and health promotion. This study examines the co-occurrence of injury and violence, substance use, hygiene, physical activity, and diet-related risk behaviors among adolescents in a rural setting on the Kenyan coast. Specifically, the study objectives were to identify clusters of HRB; based on five categories of health risk behavior, and to identify the factors associated with HRB clustering.

METHODS

A cross-sectional survey was conducted of a random sample of 1060 adolescents aged 13-19 years living within the area covered by the Kilifi Health and Demographic Surveillance System. Participants completed a questionnaire on health behaviors which was administered via an Audio Computer-Assisted Self-Interview. Latent class analysis on 13 behavioral factors (injury and violence, hygiene, alcohol tobacco and drug use, physical activity, and dietary related behavior) was used to identify clustering and stepwise ordinal logistic regression with nonparametric bootstrapping identified the factors associated with clustering. The variables of age, sex, education level, school attendance, mental health, form of residence and level of parental monitoring were included in the initial stepwise regression model.

RESULTS

We identified 3 behavioral clusters (Cluster 1: Low-risk takers (22.9%); Cluster 2: Moderate risk-takers (67.8%); Cluster 3: High risk-takers (9.3%)). Relative to the cluster 1, membership of higher risk clusters (i.e. moderate or high risk-takers) was strongly associated with older age (p<0.001), being male (p<0.001), depressive symptoms (p = 0.005), school non-attendance (p = 0.001) and a low level of parental monitoring (p<0.001).

CONCLUSION

There is clustering of health risk behaviors that underlies communicable and non-communicable diseases among adolescents in rural coastal Kenya. This suggests the urgent need for targeted multi-component health behavior interventions that simultaneously address all aspects of adolescent health and well-being, including the mental health needs of adolescents.

Effectiveness of a brief lay counsellor-delivered, problem-solving intervention for adolescent mental health problems in urban, low-income schools in India: a randomised controlled trial

BACKGROUND

Mental health problems are a leading cause of disability in adolescents worldwide. Problem solving is a well-tested mental health intervention in many populations. We aimed to investigate the effectiveness of a brief, transdiagnostic problem-solving intervention for common adolescent mental health problems when delivered by non-specialist school counsellors in New Delhi, India.

METHODS

This randomised trial was done in six government-run schools (three all-boys schools, two all-girls schools, and one co-educational school) that serve low-income communities. We recruited participants from grades 9 to 12 (ages 12-20 years) by selecting students with persistently elevated mental health symptoms accompanied by distress or functional impairment. Clinical eligibility criteria were assessed by research assistants using the Hindi-language version of the Strengths and Difficulties Questionnaire (SDQ), with reference to locally validated borderline cutoff scores of 19 or greater for boys and 20 or greater for girls on the SDQ Total Difficulties scale, an abnormal score of 2 or more on the SDQ Impact scale, and persistence of more than 1 month on the SDQ Chronicity index. Participants were randomly allocated (1:1) to problem solving delivered through a brief (2-3 week) counsellor-led intervention with supporting printed materials (intervention group), or problem solving delivered via printed booklets alone (control group). Primary outcomes were adolescent-reported mental health symptoms (SDQ Total Difficulties scale) and idiographic psychosocial problems (Youth Top Problems [YTP]) at 6 weeks. Primary analyses were done on an intention-to-treat basis at the 6-week endpoint. The trial is registered with ClinicalTrials.gov, NCT03630471.

FINDINGS

Participants were enrolled between Aug 20, and Dec 4, 2018. 283 eligible adolescents were referred to the trial, and 251 (89%) of these were enrolled (mean age 15·61 years; 174 [69%] boys). 125 participants were allocated to each group (after accounting for one participant in the intervention group who withdrew consent after randomisation). Primary outcome data were available for 245 (98%) participants. At 6 weeks, the mean YTP scores were 3·52 (SD 2·66) in the intervention group and 4·60 (2·75) in the control group (adjusted mean difference -1·01, 95% CI -1·63 to -0·38; adjusted effect size 0·36, 95% CI 0·11 to 0·61; p=0·0015). The mean SDQ Total Difficulties scores were 17·48 (5·45) in the intervention group and 18·33 (5·45) in the control group (-0·86, -2·14 to 0·41; 0·16, -0·09 to 0·41; p=0·18). We observed no adverse events.

INTERPRETATION

A brief lay counsellor-delivered problem-solving intervention combined with printed booklets seemed to have a modest effect on psychosocial outcomes among adolescents with diverse mental health problems compared with problem-solving booklets alone. This counsellor-delivered intervention might be a suitable first-line intervention in a stepped care approach, which is being evaluated in ongoing studies.

Behavioural and socio-ecological factors that influence access and utilisation of health services by young people living in rural KwaZulu-Natal, South Africa: Implications for intervention

BACKGROUND

Young people's health service utilisation (the number accessing a facility) has been the focus of guidelines and health systems strengthening policies. This is due to young people being at an increased health risk because of inequitable access and utilisation of health services, which is more pronounced in rural settings with limited service availability. This is a major concern as globally, youth constitute a considerable and increasing part of the population in Sub-Saharan Africa.

OBJECTIVE

The objective of this paper is to present a comprehensive approach for the exploration of health service utilisation by young people in rural KwaZulu-Natal, South Africa. We examined barriers and facilitators conceptualised by the constructs of the Theory of Planned Behaviour, framed within a socio-ecological model.

METHODS

Data were collected in January to June 2017 from two sites using in-depth interviews, spiral transect walks and community mapping with young people (aged 10 to 24 years), primary care health providers, school health professionals, community stakeholders and young people's parents.

RESULTS

Socio-ecological and behavioural factors influenced young people's intention to use services. Barriers included perceived negative attitudes of health providers and perceived poor staff competencies. Facilitators included an appreciation of receiving health education and assumed improved health. At social and community levels, normative beliefs hindered young people from utilising services as they feared stigmatisation and gossip. At a public policy level, structural elements had a disempowering effect as the physical layout of the clinics hindered utilisation, limited resources influenced staffing, and facility opening times were not convenient for school goers.

CONCLUSION

We suggest that to fully appreciate the complexity of health service utilisation, it is necessary to not only consider factors and processes relevant to the individual, but also acknowledge and act upon, the disjuncture between community level cultural values, norms and national policies.

Linking health facility data from young adults aged 18-24 years to longitudinal demographic data: Experience from The Kilifi Health and Demographic Surveillance System

Background: In 2014, a pilot study was conducted to test the feasibility of linking clinic attendance data for young adults at two health facilities to the population register of the Kilifi Health and Demographic Surveillance System (KHDSS). This was part of a cross-sectional survey of health problems of young people, and we tested the feasibility of using the KHDSS platform for the monitoring of future interventions.

Methods: Two facilities were used for this study. Clinical data from consenting participants aged 18-24 years were matched to KHDSS records. Data matching was achieved using national identity card numbers or otherwise using a matching algorithm based on names, sex, date of birth, location of residence and the names of other homestead members. A study form was administered to all matched patients to capture reasons for their visits and time taken to access the services. Distance to health facility from a participants’ homestead was also computed.

Results: 628 participated in the study: 386 (61%) at Matsangoni Health Centre, and 242 (39%) at Pingilikani Dispensary. 610 (97%) records were matched to the KHDSS register. Most records (605; 96%) were matched within these health facilities, while 5 (1%) were matched during homestead follow-up visits.  463 (75.9%) of those matched were women. Antenatal care (25%), family planning (13%), respiratory infections (9%) and malaria (9%) were the main reasons for seeking care. Antenatal clinic visits (n=175) and malaria (n=27) were the commonest reasons among women and men, respectively. Participants took 1-1.5 hours to access the services; 490 (81.0%) participants lived within 5 kilometres of a facility.

Conclusions: With a full-time research clerk at each health facility, linking health-facility attendance data to a longitudinal HDSS platform was feasible and could be used to monitor and evaluate the impact of health interventions on health care outcomes among young people.

Primary healthcare and school health service utilisation by adolescents and young adults in KwaZulu-Natal, South Africa

BACKGROUND

Young people aged 10-24 years are a vulnerable group with poor health service access relative to other populations. Recent South African initiatives, the She Conquers campaign, the Integrated School Health Policy and the Adolescent & Youth Health Policy, include a focus on improving the breadth and quality of youth-friendly health service delivery. However, in some settings the provision and impact of scaled-up youth friendly health services has been limited indicating a gap between policy and implementation. In this study we reviewed existing sources of data on health service utilisation to answer the following question: 'What health conditions do young people present with and what services do they receive at public health clinics, mobile clinics and school health services?'

METHODS

We conducted a retrospective register review in three purposively selected primary healthcare clinics (PHCC), one mobile clinic, and one school health team in Hlabisa and Mtubatuba sub-districts of uMkhanyakude District, KwaZulu-Natal, South Africa. The focus was service utilisation for any reason by 10-24 year olds. We also conducted descriptive analysis of pre-existing data on service utilisation by young people available from the District Health Information System for all 17 PHCC in the study sub-districts.

RESULTS

Three quarters of 4121 recorded young person visits in the register review were by females, and 40% of all young person visits were by females aged 20-24 years. The most common presenting conditions were HIV-related, antenatal care, family planning, general non-specific complaints and respiratory problems (excluding TB). There were relatively few recorded consultations for other common conditions affecting young people such as mental health and nutritional problems. Antibiotics, antiretrovirals, contraceptives, vitamins/supplements, and analgesics were most commonly provided. Routine health registers recorded limited information, were often incomplete and/or inconsistent, and age was not routinely recorded.

CONCLUSIONS

Measuring morbidity and service provision are fundamental to informing policy and promoting responsive health systems. Efforts should be intensified to improve the quality and completeness of health registers, with attention to the documentation of important, and currently poorly documented, young people's health issues such as mental health and nutrition.

Challenges and opportunities in evaluating programmes incorporating human-centred design: lessons learnt from the evaluation of Adolescents 360

Adolescents 360 (A360) is a four-year initiative (2016-2020) to increase 15-19-year-old girls' use of modern contraception in Nigeria, Ethiopia and Tanzania. The innovative A360 approach is led by human-centred design (HCD), combined with social marketing, developmental neuroscience, public health, sociocultural anthropology and youth engagement 'lenses', and aims to create context-specific, youth-driven solutions that respond to the needs of adolescent girls. The A360 external evaluation includes a process evaluation, quasi-experimental outcome evaluation, and a cost-effectiveness study. We reflect on evaluation opportunities and challenges associated with measuring the application and impact of this novel HCD-led design approach. For the process evaluation, participant observations were key to capturing the depth of the fast-paced, highly-iterative HCD process, and to understand decision-making within the design process. The evaluation team had to be flexible and align closely with the work plan of the implementers. The HCD process meant that key information such as intervention components, settings, and eligible populations were unclear and changed over outcome evaluation and cost-effectiveness protocol development. This resulted in a more time-consuming and resource-intensive study design process. As much time and resources went into the creation of a new design approach, separating one-off "creation" costs versus those costs associated with actually implementing the programme was challenging. Opportunities included the potential to inform programmatic decision-making in real-time to ensure that interventions adequately met the contextualized needs in targeted areas. Robust evaluation of interventions designed using HCD, a promising and increasingly popular approach, is warranted yet challenging. Future HCD-based initiatives should consider a phased evaluation, focusing initially on programme theory refinement and process evaluation, and then, when the intervention program details are clearer, following with outcome evaluation and cost-effectiveness analysis. A phased approach would delay the availability of evaluation findings but would allow for a more appropriate and tailored evaluation design.

Exploring adolescents and young people's candidacy for utilising health services in a rural district, South Africa

BACKGROUND

We use the 'candidacy framework' to describe adolescents' and young people's (AYP) experiences of health services in a rural KwaZulu-Natal district, South Africa.

METHODS

A qualitative approach was used including group discussions, in-depth and key informant interviews with a purposive sample of AYP (n = 70), community leaders (n = 15), school health teams (n = 10), and health service providers (n = 6).

RESULTS

Findings indicate tacit understanding among AYP that they are candidates for general health services. However, HIV stigma, apprehensions and misconceptions about sexual and reproductive health, and socio-cultural views which disapprove of AYP pre-marital sex undermine their candidacy for sexual and reproductive services.

CONCLUSION

Consideration and understanding of the vulnerabilities and reasons AYP exclude themselves will inform interventions to address their health needs. AYP's participation in the design of health services will increase their acceptability and encourage uptake of services.

Sexuality, fertility and family planning characteristics of married women aged 15 to 19 years in Ethiopia, Nigeria and Tanzania: a comparative analysis of cross-sectional data

Background

Adolescents 360 (A360) is an initiative being rolled out across Ethiopia, Nigeria and Tanzania with the aim of increasing uptake of voluntary modern contraception among sexually active women aged 15 to 19 years. Using evaluation baseline survey data, we described key sexuality, fertility and contraceptive use characteristics of married women aged 15 to 19 years living in three sub-national settings.

Methods

Cross-sectional baseline surveys of married women aged 15 to 19 years were conducted in Oromia (Ethiopia), Nasarawa (Northern Nigeria), and Mwanza (Tanzania) between August 2017 and February 2018. We also interviewed the husbands of a sub-group of married respondents to measure spousal acceptance and support for adolescent women to use modern contraception. A clustered sampling design was used in all three countries. We produced descriptive statistics on the socio-demographic and sexual and reproductive health characteristics of married women aged 15 to 19 years by study setting.

Results

In Oromia, Nasarawa and Mwanza, 31.4% (327/1198), 27.4% (1321/4816) and 7.5% (15/201) of married women surveyed had no education, and 68.3, 81.3 and 83.1% had ever been pregnant, respectively. Unmet need for modern contraception was 20.5, 21.9 and 32.0% in married women in Oromia, Nasarawa and Mwanza, made up almost entirely of unmet need for spacing. The vast majority of married women surveyed in Oromia (89.1%) and Mwanza (90.1%) had seen or heard about contraception in the last 12 months, compared to 30.1% of those surveyed in Nasarawa. Modern contraceptive prevalence (mCPR) was highest in married women aged 15 to 19 years in Oromia (47.2%), followed by Mwanza (19.4%) and Nasarawa (8.7%). Of those using a modern method of contraception in Oromia, 93.4% were using injectables or long-acting methods, compared to 49.4% in Nasarawa and 69.6% in Mwanza.

Conclusions

Overall, unmet need for modern contraception is high among married women aged 15 to 19 years across the three settings. mCPR for married women aged 15 to 19 years is low in Nasarawa and Mwanza. Ultimately, no single intervention will suit all situations, but improving the quality, analyses and utilisation of subnational data can help decision-makers design more context specific interventions.

Who are the male sexual partners of adolescent girls and young women? Comparative analysis of population data in three settings prior to DREAMS roll-out

BACKGROUND

The DREAMS (Determined Resilient Empowered AIDS-free, Mentored and Safe) Partnership aims to reduce HIV incidence among adolescent girls and young women (AGYW,15-24y) with a core package of evidence-based interventions. Some interventions, including voluntary HIV counselling and testing and circumcision, will be targeted at the male sexual partners of AGYW. A priority of DREAMS is to characterise the male partners for effective targeting.

METHODS

Using population-based data (2010-2015) in three DREAMS impact evaluation settings in Kenya and South Africa, we describe the demographic characteristics and sexual behaviour of male partners reported by AGYW, and the characteristics of males who report sexual activity with AGYW.

RESULTS

In all settings, over 90% of recent male partners reported by AGYW were aged <35 years. Median ages of spousal and non-spousal partners were 29 and 23 years respectively in uMkhanyakude (rural South Africa) and 21 and 20 years respectively in Nairobi (urban Kenya). Most males reporting an AGYW partner had never been married (89%) and many were in school (39%). Most male partners reported only 1 AGYW partner in the past year; in Gem (rural Kenya) and Nairobi 25%-29% reported 2+(AGYW or older female) partners. Concurrent partners were reported by 16% of male partners in Gem and 3-4% in uMkhanyakude. Two thirds of male partners in Gem reported testing for HIV in the past 6 months and under half in uMkhanyakude reported testing for HIV in the past year. Almost all (96%) partners in Nairobi were circumcised, compared to 45% in Gem and 43% in uMkhanyakude.

CONCLUSIONS

With almost all AGYW's sexual partners aged 15-34 years, this is an appropriate target group for DREAMS interventions. Encouraging young men to reduce their number of partners and concurrency, and uptake prevention and treatment services such as HIV testing, circumcision and ART is crucial in the effort to reduce HIV among both AGYW and young men.

Donor-Derived Metastatic Melanoma and Checkpoint Inhibition

Donor-derived malignancy, particularly melanoma, is a rare but known complication of organ transplantation. Here we describe a case of metastatic melanoma in a deceased-donor kidney transplant recipient. After diagnosis, the patient was successfully treated with cessation of immunosuppression, explantation of the renal allograft, and novel melanoma therapies, including the mutation-targeted agents dabrafenib and trametinib and the immune checkpoint inhibitor nivolumab. These 2 new classes of melanoma therapy have revolutionized the course of metastatic melanoma, altering it from one of nearly certain mortality to one of potential cure. This case reviews the mechanisms of action of these therapies and reports our experience with them in the rare setting of donor-derived melanoma in a dialysis-dependent patient.

Psychometric evaluation of the Major Depression Inventory among young people living in Coastal Kenya

Background: The lack of reliable, valid and adequately standardized measures of mental illnesses in sub-Saharan Africa is a key challenge for epidemiological studies on mental health.  We evaluated the psychometric properties and feasibility of using a computerized version of the Major Depression Inventory (MDI) in an epidemiological study in rural Kenya.

Methods: We surveyed 1496 participants aged 13-24 years in Kilifi County, on the Kenyan coast. The MDI was administered using a computer-assisted system, available in three languages. Internal consistency was evaluated using both Cronbach’s alpha and the Omega Coefficient. Confirmatory factor analysis was performed to evaluate the factorial structure of the MDI.

Results:  Internal consistency using both Cronbach’s Alpha (α= 0.83) and the Omega Coefficient (0.82; 95% confidence interval 0.81- 0.83) was above acceptable thresholds. Confirmatory factor analysis indicated a good fit of the data to a unidimensional model of MDI (χ ² (33, N = 1409) = 178.52 p < 0.001, TLI = 0.947, CFI = 0.961, and Root Mean Square Error of Approximation, RMSEA = .056), and this was confirmed using Item Response Models (Loevinger’s H coefficient 0.38) that proved the MDI was a unidimensional scale. Equivalence evaluation indicated invariance across sex and age groups. In our population, 3.6% of the youth presented with scores suggesting major depression using the ICD-10 scoring algorithm, and 8.7% presented with total scores indicating presence of depression (mild, moderate or severe).  Females and older youth were at the highest risk of depression.

Conclusions: The MDI has good psychometric properties.  Given its brevity, relative ease of usage and ability to identify at-risk youth, it may be useful for epidemiological studies of depression in Africa.  Studies to establish clinical thresholds for depression are recommended. The high prevalence of depressive symptoms suggests that depression may be an important public health problem in this population group.

Conclusions: With a full-time research clerk at each health facility, linking health-facility attendance data to a longitudinal HDSS platform was feasible and could be used to monitor and evaluate the impact of health interventions on health care outcomes among young people.

Identification of Risk Factors Associated With Clostridium difficile Infection in Liver Transplantation Recipients: A Single-Center Analysis

Clostridium difficile remains the leading cause of health care-associated infectious diarrhea, and its incidence and severity are increasing in liver transplant recipients. Several known risk factors for C difficile infection (CDI) are inherently associated with liver transplantation, such as severe underlying illness, immunosuppression, abdominal surgery, and broad-spectrum antibiotic use. We conducted a single-center retrospective case control study to characterize risk factors for CDI among patients who received a liver transplant from January 2008 to December 2012. We also examined the associations of post-transplantation CDI with transplant outcomes. Cases were defined as having diarrhea with a positive test for C difficile by either toxin A/B enzyme immunoassay (EIA) or glutamate dehydrogenase EIA and polymerase chain reaction within 1 year after transplantation. Sixty-five consecutive patients were evaluated, of which 15 (23%) developed CDI. The median time from transplantation to CDI diagnosis was 65 days (interquartile range [IQR] 13-208) and more than one-half (53%) had severe infection. Risk factors that were associated with CDI among liver transplant recipients included: (1) previous history of CDI (20% vs 0%; P = .001); (2) exposure to proton-pump inhibitor therapy (93% vs 60%; P = .015); (3) antimicrobial therapy before transplantation (47% vs 18%; P = .039); (4) a prolonged length of stay before transplantation (1 day [IQR, 1-19] vs 1 day [IQR, 0-1]; P = .028); and (5) chronic kidney disease (53% vs 20%; P = .011). There was no significant differences in patient survivals at 6 months (93% vs 96%; P = .67) and 12 months (87% vs 94%; P = .35) among CDI case and control subjects, respectively.

Serum creatinine elevation after switch to dolutegravir in a human immunodeficiency virus-positive kidney transplant recipient

Dolutegravir is a preferred antiretroviral drug for human immunodeficiency virus (HIV)-infected patients following solid organ transplantation. It has potent antiretroviral activity and does not interact with calcineurin inhibitors. We describe a case of an HIV-infected kidney transplant patient, who was noted to have a rising serum creatinine following initiation of dolutegravir. At first, an acute rejection episode was suspected, but this finding was later attributed to inhibition of creatinine secretion by dolutegravir. We suggest that an awareness of this potential effect of dolutegravir is important for providers who take care of HIV-positive kidney transplant recipients, in order to prevent potentially unnecessary testing.

Low rates of vaccination in listed kidney transplant candidates

Despite clear consensus and strong recommendations, vaccination rates of kidney transplant (KT) recipients have remained below targets. As vaccination is most effective if it is given prior to transplantation and the initiation of immunosuppression, patients should ideally have their vaccination status assessed and optimized in the pre-transplant period. We performed a retrospective chart review to characterize vaccination rates and factors associated with gaps in vaccination in a single-center population of waitlisted patients being evaluated for kidney transplantation. We evaluated 362 KT patients. Three-quarters were receiving dialysis at the time of evaluation. Immunization rates were low with 35.9% of patients having completed vaccination for Pneumococcus, 55% for influenza, 6.9% for zoster, and 2.5% for tetanus. On multivariable analysis, patients who received other vaccines, including influenza, tetanus, or zoster vaccine (odds ratio [OR] 10.55, 95% confidence interval [CI] 5.65-19.71) were more likely to receive pneumococcal vaccine. Blacks (OR 0.24, 95% CI 0.12-0.47) were less likely to receive pneumococcal vaccine compared to whites. Patients on dialysis, and those active on the waiting list were more likely to receive pneumococcal vaccine than other groups (OR 2.81, 95% CI 1.44-5.51, and OR 1.84, 95% CI 1.08-3.14, respectively). We found that the overall immunization rate against common vaccine-preventable infections was low among patients evaluated for kidney transplantation. A significant gap remains between recommendations and vaccine uptake in clinical practice among this high-risk population.

Trends and Patterns in Reporting of Patient Safety Situations in Transplantation

Analysis and dissemination of transplant patient safety data are essential to understanding key issues facing the transplant community and fostering a "culture of safety." The Organ Procurement and Transplantation Network's (OPTN) Operations and Safety Committee de-identified safety situations reported through several mechanisms, including the OPTN's online patient safety portal, through which the number of reported cases has risen sharply. From 2012 to 2013, 438 events were received through either the online portal or other reporting pathways, and about half were self-reports. Communication breakdowns (22.8%) and testing issues (16.0%) were the most common types. Events included preventable errors that led to organ discard as well as near misses. Among events reported by Organ Procurement Organization (OPOs), half came from just 10 of the 58 institutions, while half of events reported by transplant centers came from just 21 of 250 institutions. Thirteen (23%) OPOs and 155 (62%) transplant centers reported no events, suggesting substantial underreporting of safety-related errors to the national database. This is the first comprehensive, published report of the OPTN's safety efforts. Our goals are to raise awareness of safety data recently reported to the OPTN, encourage additional reporting, and spur systems improvements to mitigate future risk.

Successful treatment of acute severe graft-versus-host-disease in a pancreas-after-kidney transplant recipient: case report

The development of acute graft-versus-host-disease (GVHD) in recipients of pancreas transplants is a rare and quite often a fatal post-transplantation complication. We present a 38-year-old male with a longstanding history of type 1 diabetes mellitus and end-stage kidney disease, with a living unrelated kidney transplant from his wife for 3 years, who received an enteric-drained 5-antigen HLA-mismatched deceased-donor pancreas. Five weeks after transplantation, he presented with spiking fevers, severe skin rash, diarrhea, pancytopenia, and increasingly abnormal liver function tests. Skin biopsies were consistent with grade 3 acute GVHD. The patient was treated for GVHD with escalated doses of tacrolimus, pulse doses of steroids, and basiliximab. He was discharged after a 4-week hospital stay with complete resolution of his rash, fever, abnormal liver enzymes, and leukopenia. He remained in good health with excellent kidney and pancreas allograft function 3 years later.

They are not always a burden: older people and child fostering in Uganda during the HIV epidemic

This qualitative study examines the role of older people (60 years and above) in fostering decisions for orphans and non-orphans within extended families in a rural Ugandan community heavily affected by HIV. Fieldwork conducted in 2006 provided information on the influence of HIV on fostering decisions through 48 individual in-depth interviews and two group interviews with foster-children and family members to develop detailed case studies related to 13 fostered adolescents. The adolescents included five non-orphans and eight orphans (five were double orphans because they had lost both parents). Older people play a very important role in fostering decisions as potential foster-parents, advisers, mediators and gatekeepers. They have a high level of authority over the foster-children, who are regarded as important resources within the extended family. With fewer potential caregivers available because of HIV-related deaths, the responsibility for fostering orphans has often fallen to surviving older people. Fostering is used by older people and the child's extended family as a strategy to ensure the welfare of the foster-child. When the foster-parent is an older person, it is also used to ensure physical and emotional support for the older person themselves. Support from the extended family towards foster households is widely reported to have been reduced by HIV by diminishing resources that would otherwise have been made available to support foster care. New initiatives and investment are required to complement community and family resources within well-managed social protection and welfare programmes. To be effective, such programmes will require adequate investment in administrative capacity and monitoring. They must aim to strengthen families and, recognizing that resources are limited, should prioritize the community's poorest households, rather than specifically targeting households with orphans or other foster-children.

Risk factors for unplanned pregnancy among young women in Tanzania

Background

With effective contraceptives available, unplanned pregnancies are preventable and educational interventions have been cited as a promising platform to increase contraceptive use through improving knowledge. However, results from trials of educational interventions have been disappointing. In order to effectively target future interventions, this study aimed to identify risk factors for unplanned pregnancy among young women in Mwanza, Tanzania.

Methods

Data were analysed from the MEMA kwa Vijiana Trial Long-term Evaluation Survey, a cross-sectional study of 13 814 young adults aged 15–30 years in Mwanza, Tanzania. Potential risk factors for unplanned pregnancy were grouped under three headings: socio-demographic, knowledge of and attitude towards sexual health, and sexual behaviour and contraceptive use. Conditional logistic regression was used to identify predictors of reported unplanned pregnancy among all sexually active women.

Results

Increasing age, lower educational level, not being currently married, knowing where to access condoms, increasing number of sexual partners and younger reported age at sexual debut were associated with unplanned pregnancy.

Discussion

A number of demographic and sexual behaviour risk factors for pregnancy are identified which will help guide future intervention programmes aiming to reduce unplanned pregnancies. This study suggests effective measures to prevent unplanned pregnancies should focus on encouraging girls to stay in school.

HIV Infection among Young People in Northwest Tanzania: The Role of Biological, Behavioural and Socio-Demographic Risk Factors

Background

Young people are at high risk of HIV and developing appropriate prevention programmes requires an understanding of the risk factors for HIV in this age group. We investigated factors associated with HIV among participants aged 15–30 years in a 2007–8 cross-sectional survey nested within a community-randomised trial of the MEMA kwa Vijana intervention in 20 rural communities in northwest Tanzania.

Methods

We analysed data for 7259(53%) males and 6476(47%) females. Using a proximate-determinant conceptual framework and conditional logistic regression, we obtained sex-specific Odds Ratios (ORs) for the association of HIV infection with socio-demographic, knowledge, behavioural and biological factors.

Results

HSV-2 infection was strongly associated with HIV infection (females: adjOR 4.4, 95%CI 3.2–6.1; males: adjOR 4.2, 95%CI 2.8–6.2). Several socio-demographic factors (such as age, marital status and mobility), behavioural factors (condom use, number and type of sexual partnerships) and biological factors (blood transfusion, lifetime pregnancies, genital ulcers, Neisseria gonorrhoeae) were also associated with HIV infection. Among females, lifetime sexual partners (linear trend, p<0.001), ≥2 partners in the past year (adjOR 2.0, 95%CI 1.4–2.8), ≥2 new partners in the past year (adjOR 1.9 95%CI 1.2, 3.3) and concurrent partners in the past year (adjOR 1.6 95%CI 1.1, 2.4) were all associated with HIV infection.

Conclusions

Efforts must be intensified to find effective interventions to reduce HSV-2. Effective behavioural interventions focusing on reducing the number of sexual partnerships and risk behaviour within partnerships are also needed. An increase in risky sexual behaviour may occur following marriage dissolution or when a young woman travels outside of her community and interventions addressing the needs of these subgroups of vulnerable women may be important.

Rapid increase in prevalence of male circumcision in rural Tanzania in the absence of a promotional campaign

Objectives

To estimate the prevalence of circumcision among young men in rural Mwanza, North-Western Tanzania, and document trends in circumcision prevalence over time. To investigate associations of circumcision with socio-demographic characteristics, reported sexual behaviours and sexually transmitted infections (STIs).

Design

A cross-sectional survey in communities which had previously participated in a cluster-randomized trial of an adolescent sexual health intervention that did not include male circumcision in 20 rural communities.

Methods

In 2007/08, 7300 young men (age 16–23 years) were interviewed and examined by a clinician. The prevalence of circumcision by age was compared with data collected during the trial in 1998–2002. Odds ratios (OR) and 95% confidence intervals (CI) for the association of circumcision with socio-demographic characteristics, reported sexual behaviours and with HIV and other STIs were estimated using multivariable conditional logistic regression.

Results

The prevalence of male circumcision was 40.6%, and age-specific prevalence had more than doubled since 2001/2002. Circumcised men reported less risky sexual behaviours, being more likely to report having ever used a condom (adjusted OR = 2.62, 95%CI:2.32–2.95). Men circumcised before sexual debut were at reduced risk of being HIV seropositive compared with non-circumcised men (adjusted OR = 0.50, 95%CI:0.25–0.97), and also had reduced risks of HSV-2 infection and genital ulcer syndrome in the past 12 months compared with non-circumcised men.

Conclusions

There was a steep increase in circumcision prevalence between 2001/02 and 2007/08 in the absence of a promotional campaign. Circumcised men reported safer sexual practices than non-circumcised men and had lower prevalence of HIV and HSV-2 infection.

The sexual behaviour of adolescents in sub-Saharan Africa: patterns and trends from national surveys

OBJECTIVES

To describe the sexual and reproductive behaviour of adolescents in sub-Saharan Africa, particularly 15- to 19-year-olds.

METHODS

 Using DHS/AIS data (2000-2010), nine indicators of adolescent behaviour and one of adult attitudes towards condom education for adolescents were described for 24 countries. Indicators were disaggregated by gender, urban/rural residency and educational status, and time trends were described.

RESULTS

Up to 25% of 15- to 19-year-olds reported sex before age 15; this proportion shrank over time in many countries. In most countries, ≥5% of females reported marriage before age 15, and >20% had commenced childbearing. Early sexual debut and childbearing were more common among the least educated and/or rural females. Reporting of multiple sexual partnerships was more common among males than among females, but decreases over time were more common among males. Urban males and females, and females with higher education, were more likely to report multiple partnerships. Urban youth and those with higher education also reported more condom use. Adult support for condom education for 12- to 14-year-olds has increased over time to 60-65%.

CONCLUSIONS

Many 15- to 19-year-olds are at risk of HIV/STIs and unplanned pregnancies because of multiple partnerships and insufficient condom and other contraceptive use. In many countries, trends are moving in a favourable direction. To better inform prevention programmes in this important area, we recommend routine collection of sexual and reproductive behaviour data for adolescents aged <15 years, expanding the data collected for 15- to 19-year-olds to include detailed information on sexual behaviour within partnerships, and disaggregating data according to sociodemographic variables.

Recall, relevance and application of an in-school sexual and reproductive health intervention 7-9 years later: perspectives of rural Tanzanian young people

Many adolescent sexual and reproductive health (ASRH) interventions have improved knowledge and reduced reported sexual risk behaviours, but found no impact on HIV. We explored potential reasons for this in 23 in-depth interviews, conducted 7-9 years after exposure to ASRH intervention. We discussed participants' memories and views of the relevance of the in-school intervention, and their subsequent ability to apply what they had learned. While most participants had favourable memories of the intervention, few recalled specific details. Most reported that the intervention had been relevant, although few reported being able to apply the teachings. Men found it easier to apply lessons about condoms than women. Inability to apply the intervention teachings was often linked to cultural norms around fertility and/or gender power relations. ASRH interventions should address structural factors such as the quality of parenting and explicitly link interventions to young peoples' future aspiration.

HIV prevention in young people in sub-Saharan Africa: a systematic review

PURPOSE

To systematically review and update evidence on the effectiveness of youth HIV/AIDS prevention interventions in sub-Saharan Africa (SSA) and to make evidence-based policy recommendations to guide efforts toward meeting the United Nations General Assembly Special Session HIV/AIDS goals.

METHODS

Recent evidence (January 2005-December 2008) on the effectiveness of interventions to improve reported sexual behavior and biological outcomes among youth in SSA was assessed using the Steady, Ready, Go! (SRG) approach and synthesized with an earlier SRG review (January 1990-June 2005).

RESULTS

A total of 23 studies were included following screening of approximately 1,200 citations. School-based, adult-led, curriculum-based interventions showed clear evidence of reducing reported risky sexual behavior. Interventions in health facilities increased the use of services when made accessible and more youth-friendly. In geographically defined communities, both interventions specifically targeting youth and community-wide interventions reduced reports of risky sexual behavior.

CONCLUSIONS

HIV prevention among youth is a top priority in SSA. The most promising interventions should be scaled-up now, with careful evaluation, while exploring supplementary interventions to impact HIV incidence.

The epidemiology of HIV among young people in sub-Saharan Africa: know your local epidemic and its implications for prevention

BACKGROUND

Broad patterns of HIV epidemiology are frequently used to design generic HIV programs in sub-Saharan Africa.

METHODS

We reviewed the epidemiology of HIV among young people in sub-Saharan Africa, and explored the unique dynamics of infection in its different regions.

RESULTS

In 2009, HIV prevalence among youth in sub-Saharan Africa was an estimated 1.4% in males and 3.4% in females, but these values mask wide variation at regional and national levels. Within countries there are further major differences in HIV prevalence, such as by sex, urban/rural location, economic status, education, or ethnic group. Within this highly nuanced context, HIV prevention programs targeting youth must consider both where new infections are occurring and where they are coming from.

CONCLUSIONS

Given the epidemiology, one-size-fits-all HIV prevention programs are usually inappropriate at regional and national levels. Consideration of local context and risk associated with life transitions, such as leaving school or getting married, is imperative to successful programming for young people.

The long-term impact of the MEMA kwa Vijana adolescent sexual and reproductive health intervention: effect of dose and time since intervention exposure

BACKGROUND

Despite recent decreases in HIV incidence in many sub-Saharan African countries, there is little evidence that specific behavioural interventions have led to a reduction in HIV among young people. Further and wider-scale decreases in HIV require better understanding of when behaviour change occurs and why. The MEMA kwa Vijana adolescent sexual and reproductive health intervention has been implemented in rural Mwanza, Tanzania since 1999. A long-term evaluation in 2007/8 found that the intervention improved knowledge, attitudes to sex and some reported risk behaviours, but not HIV or HSV2 prevalence. The aim of this paper was to assess the differential impact of the intervention according to gender, age, marital status, number of years of exposure and time since last exposure to the intervention.

METHODS

In 2007, a cross-sectional survey was conducted in the 20 trial communities among 13,814 young people (15-30 yrs) who had attended intervention or comparison schools between 1999 and 2002. Outcomes for which the intervention had an impact in 2001 or 2007 were included in this subgroup analysis. Data were analysed using cluster-level methods for stratified cluster-randomised trials, using interaction tests to determine if intervention impact differed by subgroup.

RESULTS

Taking into account multiplicity of testing, concurrence with a priori hypotheses and consistency within the results no strong effect-modifiers emerged. Impact on pregnancy knowledge and reported attitudes to sex increased with years of exposure to high-quality intervention.

CONCLUSIONS

The desirable long-term impact of the MEMA kwa Vijana intervention did not vary greatly according to the subgroups examined. This suggests that the intervention can have an impact on a broad cross-section of young people in rural Mwanza.

Factors associated with self-disclosure of HIV serostatus to significant others

OBJECTIVES

To examine rates and patterns of self-disclosure of HIV serostatus amongst individuals attending an out-patient HIV clinic in East London.

DESIGN

A cross-sectional survey design was used.

METHODS

A volunteer sample of 95 out-patient HIV clinic attendees completed a self-report questionnaire examining patterns of disclosure to self-identified significant others, reasons for disclosure and non-disclosure, satisfaction with social support (SSQ6), quality of life (MOS-30) and anxiety and depression (HADS). Self-disclosure was examined in relation to cultural background, gender, satisfaction with social support, and medical and psychological variables.

RESULTS

Seventy-nine men and 16 women reported a mean disclosure rate of 68% to self-identified significant others. Five individuals had not disclosed their HIV status to anyone; 91% of individuals had informed their partner. Friends were more frequently informed (79%) than family (53%). Ethnicity (p <.001) and length of time since testing HIV seropositive (p <.05) emerged as significant predictors of disclosure. Global satisfaction with social support was negatively correlated with depression but was not associated with the total rate of HIV disclosure. Frequently reported reasons for non-disclosure included wanting to protect others from distress and fear of discrimination.

CONCLUSIONS

Self-disclosure of HIV serostatus rates was highest for partners, followed by friends, and lowest for family members. Patterns of disclosure of HIV serostatus varied in relation to ethnicity. Fifteen years into the HIV epidemic, social stigma continues to contribute towards non-disclosure of diagnosis.

Long-term biological and behavioural impact of an adolescent sexual health intervention in Tanzania: follow-up survey of the community-based MEMA kwa Vijana Trial

BACKGROUND

The ability of specific behaviour-change interventions to reduce HIV infection in young people remains questionable. Since January 1999, an adolescent sexual and reproductive health (SRH) intervention has been implemented in ten randomly chosen intervention communities in rural Tanzania, within a community randomised trial (see below; NCT00248469). The intervention consisted of teacher-led, peer-assisted in-school education, youth-friendly health services, community activities, and youth condom promotion and distribution. Process evaluation in 1999-2002 showed high intervention quality and coverage. A 2001/2 intervention impact evaluation showed no impact on the primary outcomes of HIV seroincidence and herpes simplex virus type 2 (HSV-2) seroprevalence but found substantial improvements in SRH knowledge, reported attitudes, and some reported sexual behaviours. It was postulated that the impact on "upstream" knowledge, attitude, and reported behaviour outcomes seen at the 3-year follow-up would, in the longer term, lead to a reduction in HIV and HSV-2 infection rates and other biological outcomes. A further impact evaluation survey in 2007/8 ( approximately 9 years post-intervention) tested this hypothesis.

METHODS AND FINDINGS

This is a cross-sectional survey (June 2007 through July 2008) of 13,814 young people aged 15-30 y who had attended trial schools during the first phase of the MEMA kwa Vijana intervention trial (1999-2002). Prevalences of the primary outcomes HIV and HSV-2 were 1.8% and 25.9% in males and 4.0% and 41.4% in females, respectively. The intervention did not significantly reduce risk of HIV (males adjusted prevalence ratio [aPR] 0.91, 95%CI 0.50-1.65; females aPR 1.07, 95%CI 0.68-1.67) or HSV-2 (males aPR 0.94, 95%CI 0.77-1.15; females aPR 0.96, 95%CI 0.87-1.06). The intervention was associated with a reduction in the proportion of males reporting more than four sexual partners in their lifetime (aPR 0.87, 95%CI 0.78-0.97) and an increase in reported condom use at last sex with a non-regular partner among females (aPR 1.34, 95%CI 1.07-1.69). There was a clear and consistent beneficial impact on knowledge, but no significant impact on reported attitudes to sexual risk, reported pregnancies, or other reported sexual behaviours. The study population was likely to have been, on average, at lower risk of HIV and other sexually transmitted infections compared to other rural populations, as only youth who had reached year five of primary school were eligible.

CONCLUSIONS

SRH knowledge can be improved and retained long-term, but this intervention had only a limited effect on reported behaviour and no significant effect on HIV/STI prevalence. Youth interventions integrated within intensive, community-wide risk reduction programmes may be more successful and should be evaluated.

Kidney disease after heart and lung transplantation

Kidney disease is a commonly recognized complication of heart and lung transplantation and is associated with increased morbidity and mortality. While the spectrum of kidney disease in this population is wide-ranging, studies indicate that between 3% and 10% of these patients will ultimately develop end-stage renal disease (ESRD). This review examines the risk factors for both acute and chronic kidney injury, with a particular emphasis on the role of calcineurin inhibitor-mediated nephrotoxicity in both these settings. Against the background of current National Kidney Foundation Kidney Disease Outcomes Quality Initiative (KDOQI) guidelines, we have further considered and recommended appropriate strategies for long-term management of kidney disease-related manifestations in heart and lung transplant recipients. Specific aspects addressed include retarding progressive renal injury and minimizing nephrotoxicity, as well as treatment of hypertension, hyperlipidemia and anemia. Finally, for patients in this population with advanced kidney disease, renal replacement therapy options are discussed. Based on the impact of chronic kidney disease on outcomes in both heart and lung recipients, we advocate early referral to a nephrologist for patients displaying evidence of significant renal dysfunction.
