INTRODUCTION: Sub-Saharan Africa is experiencing an epidemiological transition as the burden of NCDs overtake communicable diseases. However, it is unknown what capacity and gaps exist at primary care level to address the growing burden of NCDs. This study aimed to assess the Zambian health system's capacity to address in NCDs, using an adapted WHO Essential Non Communicable Disease Interventions (WHO PEN) tool. METHODOLOGY: This was a cross-sectional facility survey in the three districts conducted from September 2017 to October 2017. We defined facility readiness along five domains: basic equipment, essential services, diagnostic capacity, counseling services, and essential medicines. For each domain, we calculated an index as the mean score of items expressed as percentage. These indices were compared to an agreed cutoff at 70%, meaning that a facility index or district index below 70% off was considered as 'not ready' to manage NCDs at that level. All analysis were performed using Stata 15 MP. RESULTS: There appeared to be wide heterogeneity between facilities in respect of readiness to manage NCDs. Only 6 (including the three 1st level hospitals) out of the 46 facilities were deemed ready to manage NCDs. Only the first level hospitals scored a mean index higher than the 70% cut off; With regard to medications needed to manage NCDs, urban and rural health facilities were comparably equipped. However, there was evidence that calcium channel blockers (p = 0.013) and insulin (p = 0.022) were more likely to be available in urban and semi-urban health facilities compared to rural facilities. CONCLUSION: Our study revealed gaps in primary health care capacity to manage NCDs in Zambia, with almost all health facilities failing to reach the minimum threshold. These results could be generalized to other similar districts in Zambia and the sub-region, where health systems remain focused on infectious rather than non-communicable Disease. These results should attract policy attention and potentially form the basis to review current approach to NCD care at the primary care level in Zambia and Sub-Saharan Africa.

BACKGROUND: Despite increasing morbidity and mortality from non-communicable diseases (NCD) globally, health systems in low- and middle-income countries (LMICs) have limited capacity to address these chronic conditions, particularly in sub-Saharan Africa (SSA). There is an urgent need, therefore, to respond to NCDs in SSA, beginning by applying lessons learned from the first global response to any chronic disease-HIV-to tackle the leading cardiometabolic killers of people living with HIV (PLHIV). We have developed a feasible and acceptable package of evidence-based interventions and a multi-faceted implementation strategy, known as "TASKPEN," that has been adapted to the Zambian setting to address hypertension, diabetes, and dyslipidemia. The TASKPEN multifaceted implementation strategy focuses on reorganizing service delivery for integrated HIV-NCD care and features task-shifting, practice facilitation, and leveraging HIV platforms for NCD care. We propose a hybrid type II effectiveness-implementation stepped-wedge cluster randomized trial to evaluate the effects of TASKPEN on clinical and implementation outcomes, including dual control of HIV and cardiometabolic NCDs, as well as quality of life, intervention reach, and cost-effectiveness. METHODS: The trial will be conducted in 12 urban health facilities in Lusaka, Zambia over a 30-month period. Clinical outcomes will be assessed via surveys with PLHIV accessing routine HIV services, and a prospective cohort of PLHIV with cardiometabolic comorbidities nested within the larger trial. We will also collect data using mixed methods, including in-depth interviews, questionnaires, focus group discussions, and structured observations, and estimate cost-effectiveness through time-and-motion studies and other costing methods, to understand implementation outcomes according to Proctor's Outcomes for Implementation Research, the Consolidated Framework for Implementation Research, and selected dimensions of RE-AIM. DISCUSSION: Findings from this study will be used to make discrete, actionable, and context-specific recommendations in Zambia and the region for integrating cardiometabolic NCD care into national HIV treatment programs. While the TASKPEN study focuses on cardiometabolic NCDs in PLHIV, the multifaceted implementation strategy studied will be relevant to other NCDs and to people without HIV. It is expected that the trial will generate new insights that enable delivery of high-quality integrated HIV-NCD care, which may improve cardiovascular morbidity and viral suppression for PLHIV in SSA. This study was registered at ClinicalTrials.gov (NCT05950919).

BACKGROUND: Sexual and gender minorities face high levels of stigma, discrimination, and violence. In many countries, they are often criminalized and are at risk of mental health challenges. In Zambia, little is known about the psychosocial challenges and coping strategies of sexual and gender minorities. This study sought to explore psychosocial challenges and coping strategies among sexual and gender minority populations in Lusaka, Zambia to inform mental health and human rights promotion for this population. METHODS: The study used a qualitative phenomenological study design. Data were collected through in-depth interviews with 16 sexual and gender minority participants (lesbian, gay, bisexual, and transgender) and four key informants. The sexual minorities included four lesbian, five gay, and three bisexual participants while the gender minorities included two transgender men and two transgender women. Interviews with gender and sexual minorities were mostly focused on the lived experiences of participants, while those of key informants focused on their work with sexual and gender minorities. Snowball strategy was used to recruit participants, while purposive sampling was used to select key informants. All interviews were recorded and transcribed verbatim. Thematic analysis was carried out with the aid of Nvivo 12 software. RESULTS: Psychosocial challenges included victimization in the form of threats and physical assault. Stigma and discrimination were experienced in different settings such as healthcare, the workplace, and school. Participants reported having experienced feelings of depression. Rejection from family members was experienced by those who revealed their sexual or gender minority status. Reported coping strategies included social support, self-concealment, listening to music, and substance use. CONCLUSION: This study suggests that sexual and gender minorities in Zambia experience various psychosocial challenges related to their sexuality and gender identity. To assist them cope better with the obstacles they experience, improved psychosocial counseling and mental health services are needed.

BACKGROUND: Adolescent school-going mothers return to school in the rekindled hope of obtaining an education. However, their re-introduction into the school environment requires adequate support from teachers, fellow pupils, and the community. The purpose of this study was to explore the experiences of school-going mothers in Lusaka to understand their coping mechanism in the process of re-integration. METHOD: This is a qualitative case study. We conducted in-depth interviews with 24 school going mothers between the ages of 16-19, purposively selected from 2 schools in Lusaka district. Audio-recorded interviews were transcribed, coded using Nvivo 10 software and analysed using thematic analysis. RESULTS: The girls reported experiencing stigmatization, discrimination, mockery and abuse from their teachers. Some community members labelled, humiliated, gossiped about and isolated the girls from their friends and classmates because of fear of 'contamination'. Families forced some girls into early marriages making them feel rejected. These experiences resulted in low self-esteem, inferiority complex, poor performance in their academic work and identity crises in the young mothers. Therefore, because of the experiences the girls faced, they developed certain behaviours such as beer drinking, truancy and running away from home. They found it difficult to adjust to motherhood while doing their schoolwork. CONCLUSION: There is a need for the teachers to undergo training on how to handle young mothers and have a flexible time-table to accommodate adolescent school going mothers when they miss lessons to attend to their babies. Non-parenting school girls should be counseled so that they do not stigmatize adolescent mothers. Parents need to be educated on how to deal with adolescent mothers in the community. The guidance office should have a qualified psychosocial counselor to help create a conducive learning environment for adolescent mothers, by helping them with missed lessons and seeing to it that they are not stigmatized.
