Evidence of Závora Bay as a critical site for reef manta rays, Mobula alfredi, in southern Mozambique

The largest known reef manta ray (Mobula alfredi) population in Africa has been monitored for more than 20 years at several locations on the coast of the Inhambane Province in southern Mozambique. Nonetheless, before this study, little had been reported on the population dynamics of M. alfredi from Závora, a remote bay in the region. Photographic mark-recapture was used to investigate the size and structure of M. alfredi that aggregate at "Red Sands," a reef cleaning station in Závora Bay. An 11 year photographic data set was used to identify 583 M. alfredi individuals between 2010 and 2021. More than half of M. alfredi individuals were resighted at least once, with most encounters (up to 18 for one individual) occurring during the peak sighting period in July-November each year. An even sex ratio was observed, 44% females and 50% males, with no significant difference in resightings between the sexes. Pollock's robust design population models were used to estimate annual abundance, emigration, annual apparent survival and capture probability at Red Sands from July to November over a 6 year period (2016-2021). Abundance estimates varied year to year, ranging from 35 (95% c.i. [30, 45]) up to 233 (95% c.i. [224, 249]) M. alfredi individuals. Given the seasonal affinity of M. alfredi observed at Red Sands, this study highlights the importance of understanding fine-scale site use within the larger home range of this population to develop local management strategies.

Implementation of the South African Triage Scale (SATS) in a New Ambulance System in Beira, Mozambique: A Retrospective Observational Study

In 2019, an urban ambulance system was deployed in the city of Beira, Mozambique to refer patients from peripheral health centres (HCs) to the only hospital of the city (Beira Central Hospital-HCB). Initially, the system worked following a first-in-first-out approach, thus leading to referrals not based on severity condition. With the aim of improving the process, the South African Triage Scale (SATS) has been subsequently introduced in three HCs. In this study, we assessed the impact of SATS implementation on the selection process and the accuracy of triage performed by nurses. We assessed 552 and 1608 referral charts from before and after SATS implementation, respectively, and we retrospectively calculated codes. We compared the expected referred patients' codes from the two phases, and nurse-assigned codes to the expected ones. The proportion of referred orange and red codes significantly increased (+12.2% and +12.9%) while the proportion of green and yellow codes decreased (-18.7% and -5.8%). The overall rates of accuracy, and under- and overtriage were 34.2%, 36.3%, and 29.5%, respectively. The implementation of SATS modified the pattern of referred patients and increased the number of severe cases receiving advanced medical care at HCB. While nurses' accuracy improved with the routine use of the protocol, the observed rates of incorrect triage suggest that further research is needed to identify factors affecting SATS application in this setting.

Validation of brief screening instruments for internalizing and externalizing disorders in Mozambican adolescents

BACKGROUND

Mental disorders are the leading cause of disability for youth worldwide. However, there is a dearth of validated, brief instruments to assess mental health in low- and middle-income countries (LMIC). We aimed to facilitate identification of mental disorders in LMIC contexts by adapting and validating measures of internalizing and externalizing disorders for adolescents in Mozambique, an LMIC in southeastern Africa.

METHODS

We selected instruments with good support for validity in high-income and other LMIC settings: the Patient Health Questionnaire Adolescent (PHQ-A), Generalized Anxiety Disorders 7 (GAD-7), and Strengths and Difficulties Questionnaire (SDQ). Instruments were adapted by local and international mental health specialists followed by cognitive interviews (n = 48) with Mozambican adolescents. We administered the instruments along with the Miniature International Neuropsychiatric Interview for Children and Adolescents (MINI-KID)to 485 adolescents aged 12-19 years attending two secondary schools in Maputo City, Mozambique. One week later, we re-administered instruments to a randomly selected sample of 49 adolescents.

RESULTS

Participants were 66.2% (n = 321) female and the average age was 15.9 (S.D = 1.7).Internal consistency (alpha = 0.80, PHQ-A; 0.84, GAD-7; 0.80, SDQ) and test-retest reliabilty (ICC = 0.74, PHQ-A; 0.70, GAD-7; 0.77, SDQ) were acceptabe for the PHQ-A, GAD-7, and the full SDQ. The SDQ internalizing subscale showed poor test-retest reliability (ICC = 0.63) and the SDQ externalizing subscale showed poor internal consistency (alpha = 0.65). All instruments demonstrated good sensitivity and specificity (> 0.70). Youden's index identified optimal cutoff scores of 8 for the PHQ-A, 5 for the GAD-7, 10 for the SDQ internalizing and 9 for the SDQ externalizing subscales, though a range of scores provided acceptable sensitivity and specificity.

CONCLUSIONS

Our data supports reliability and validity of the PHQ-A, GAD-7, and SDQ instruments for rapidly assessing mental health problems in Mozambican adolescents. Use of these tools in other contexts with limited specialists may asist with expanding mental health assessment. Specific instrument and cutoff selection should be based on screening goals, treatment resources, and program objectives.

Fostering Sustainable Biomedical Research Training in Mozambique: A Spin-Off of the Medical Education Partnership Initiative

Background

The further development of research capacity in low- and middle-income countries is critical to the delivery of evidence-based healthcare, the design of sound health policy and effective resource allocation. Research capacity is also critical for the retention of highly skilled faculty and staff and for institutional internationalization.

Objectives

We summarize the accomplishments, challenges and legacy of a five-year program to train biomedical researchers entitled "Enhanced Advanced Biomedical Research Training for Mozambique (EABRTM)".

Methods

A program conducted from 2015-2021 built upon the Medical Education Partnership Initiative to develop research capacity at Eduardo Mondlane University (UEM) and allied institutions. The project included design and implementation of postgraduate training programs and bolstered physical and human research infrastructure.

Findings

The program supported development and implementation of UEM's first doctoral (Bioscience and Public Health) and master (Biosciences) programs with 31 and 23 students enrolled to date, respectively. Three master programs were established at Lúrio University from which 176/202 (87.1%) and 107/202 (53.0%) students obtained a Postgraduate Diploma or master's degree, respectively. Scholarships were awarded to 39 biomedical researchers; 13 completed master degrees, one completed a PhD and five remain in doctoral studies. Thirteen administrative staff and four biomedical researchers were trained in research administration and in biostatistics, respectively. A total of 119 courses and seminars benefited 2,142 participants. Thirty-five manuscripts have been published to date in peer-reviewed international journals of which 77% are first-authored by Mozambicans and 44% last-authored by Africans. Sustainability was achieved through 59 research projects awarded by international agencies, totaling $16,363,656.42 and funds ($ 7,319,366.11) secured through 2025.

Conclusions

The EABRTM program substantially increased research and mentorship capacity and trained a new generation of biostatisticians and research administrators. These programmatic outcomes significantly increased the confidence of early stage Mozambican researchers in their ability to successfully pursue their career goals.

Association Between Girl-child Marriage and Intimate Partner Violence in Sub-Saharan Africa: Insights From a Multicountry Analysis of Demographic and Health Surveys

While considerable attention has been given to the health consequences of child marriage in Sub-Saharan Africa (SSA), limited studies exist on its impact on intimate partner violence (IPV) in the region. We address this gap by examining the link between child marriage and IPV. We tested our study hypothesis using demographic and health survey data of 28,206 young women aged 20-24 years from 16 SSA countries with recent surveys (2015-2019). Binary logistic regression models were used to examine the effect of child marriage on IPV. Child marriage prevalence ranged from 13.5% in Rwanda, in East Africa, to 77% in Chad, in Central Africa, while IPV ranged from 17.5% in Mozambique in Southern Africa to 42% in Uganda, in East Africa. Past year experience of IPV was higher among young women who married or begun cohabiting before the age of 18 (36.9%) than those who did at age 18 or more (32.5%). This result was consistent for all forms of violence: physical violence (22.7% vs 19.7%), emotional violence (25.3% vs 21.9%), and sexual violence (12% vs 10.4%). After controlling for covariates, we found that young women in SSA who married before 18 years were more likely to experience IPV than those who married as adults (AOR: 1.20; 95% CI [1.12, 1.29]). Significant heterogeneity was observed in the country-level results, with a higher likelihood of IPV found in 14 of the 16 countries and lower in Angola and Chad. Child marriage is associated with a higher likelihood of IPV in most SSA countries, suggesting that ending child marriage will result in a substantial reduction in IPV. There is a need to institute policies to support and protect women who marry as children from abusive relationships in SSA.

To spray or target mosquitoes another way: focused entomological intelligence guides the implementation of indoor residual spraying in southern Mozambique

BACKGROUND

To eliminate malaria in southern Mozambique, the National Malaria Control Programme and its partners are scaling up indoor residual spraying (IRS) activities in two provinces, Gaza and Inhambane. An entomological surveillance planning tool (ESPT) was used to answer the programmatic question of whether IRS would be effective in target geographies, given limited information on local vector bionomics.

METHODS

Entomological intelligence was collected in six sentinel sites at the end of the rainy season (April-May 2018) and the beginning of the dry season (June-July 2018). The primary objective was to provide an 'entomological snapshot' by collecting question-based, timely and high-quality data within one single week in each location. Host-seeking behaviour (both indoors and outdoors) was monitored by human-baited tent traps. Indoor resting behaviour was quantified by pyrethrum spray catches and window exit traps.

RESULTS

Five different species or species groups were identified: Anopheles funestus sensu lato (s.l.) (66.0%), Anopheles gambiae s.l. (14.0%), Anopheles pharoensis (1.4%), Anopheles tenebrosus (14.1%) and Anopheles ziemanni (4.5%). Anopheles funestus sensu stricto (s.s.) was the major vector among its sibling species, and 1.9% were positive for Plasmodium falciparum infections. Anopheles arabiensis was the most abundant vector species within the An. gambiae complex, but none tested positive for P. falciparum infections. Some An. tenebrosus were positive for P. falciparum (1.3%). When evaluating behaviours that impact IRS efficacy, i.e. endophily, the known primary vector An. funestus s.s., was found to rest indoors-demonstrating at least part of its population will be impacted by the intervention if insecticides are selected to which this vector is susceptible. However, other vector species, including An. gambiae s.l., An. tenebrosus, An. pharoensis and An. ziemanni, showed exophilic and exophagic behaviours in several of the districts surveilled.

CONCLUSION

The targeted approach to entomological surveillance was successful in collecting question-based entomological intelligence to inform decision-making about the use of IRS in specific districts. Endophilic An. funestus s.s. was documented as being the most prevalent and primary malaria vector suggesting that IRS can reduce malaria transmission, but the presence of other vector species both indoors and outdoors suggests that alternative vector control interventions that target these gaps in protection may increase the impact of vector control in southern Mozambique.

"If it weren't for my traditional healer, I would be dead": Engaging traditional healers to support people living with HIV in rural Mozambique

Across rural sub-Saharan Africa, people living with HIV (PLHIV) commonly seek out treatment from traditional healers. We report on the clinical outcomes of a community health worker intervention adapted for traditional healers with insight into our results from qualitative interviews. We employed a pre-post intervention study design and used sequential mixed methods to assess the impact of a traditional healer support worker intervention in Zambézia province, Mozambique. After receiving a positive test result, 276 participants who were newly enrolled in HIV treatment and were interested in receiving home-based support from a traditional healer were recruited into the study. Those who enrolled from February 2016 to August 2016 received standard of care services, while those who enrolled from June 2017 to May 2018 received support from a traditional healer. We conducted interviews among healers and participants to gain insight into fidelity of study activities, barriers to support, and program improvement. Medication possession ratio at home (based on pharmacy pick-up dates) was not significantly different between pre- and post-intervention participants (0.80 in the pre-intervention group compared to 0.79 in the post-intervention group; p = 0.96). Participants reported receiving educational and psychosocial support from healers. Healers adapted their support protocol to initiate directly observed therapy among participants with poor adherence. Traditional healers can provide community-based psychosocial support, education, directly observed therapy, and disclosure assistance for PLHIV. Multiple factors may hinder patients' desire and ability to remain adherent to treatment, including poverty, confusion about medication side effects, and frustration with wait times at the health facility.

Systems analysis and improvement approach to optimize outpatient mental health treatment cascades in Mozambique (SAIA-MH): study protocol for a cluster randomized trial

BACKGROUND

Significant investments are being made to close the mental health (MH) treatment gap, which often exceeds 90% in many low- and middle-income countries (LMICs). However, limited attention has been paid to patient quality of care in nascent and evolving LMIC MH systems. In system assessments across sub-Saharan Africa, MH loss-to-follow-up often exceeds 50% and sub-optimal medication adherence often exceeds 60%. This study aims to fill a gap of evidence-based implementation strategies targeting the optimization of MH treatment cascades in LMICs by testing a low-cost multicomponent implementation strategy integrated into routine government MH care in Mozambique.

METHODS

Using a cluster-randomized trial design, 16 clinics (8 intervention and 8 control) providing primary MH care will be randomized to the Systems Analysis and Improvement Approach for Mental Health (SAIA-MH) or an attentional placebo control. SAIA-MH is a multicomponent implementation strategy blending external facilitation, clinical consultation, and provider team meetings with system-engineering tools in an overall continuous quality improvement framework. Following a 6-month baseline period, intervention facilities will implement the SAIA-MH strategy for a 2-year intensive implementation period, followed by a 1-year sustainment phase. Primary outcomes will be the proportion of all patients diagnosed with a MH condition and receiving pharmaceutical-based treatment who achieve functional improvement, adherence to medication, and retention in MH care. The Consolidated Framework for Implementation Research (CFIR) will be used to assess determinants of implementation success. Specific Aim 1b will include the evaluation of mechanisms of the SAIA-MH strategy using longitudinal structural equation modeling as well as specific aim 2 estimating cost and cost-effectiveness of scaling-up SAIA-MH in Mozambique to provincial and national levels.

DISCUSSION

This study is innovative in being the first, to our knowledge, to test a multicomponent implementation strategy for MH care cascade optimization in LMICs. By design, SAIA-MH is a low-cost strategy to generate contextually relevant solutions to barriers to effective primary MH care, and thus focuses on system improvements that can be sustained over the long term. Since SAIA-MH is integrated into routine government MH service delivery, this pragmatic trial has the potential to inform potential SAIA-MH scale-up in Mozambique and other similar LMICs.

Being dragged into adulthood? Young people's agency concerning sex, relationships and marriage in Malawi, Mozambique and Zambia

This study aimed to explore how young people exercise agency in rural Malawi, Mozambique and Zambia in relation to sex, relationships and marriage, to inform local programmes aiming to prevent teenage pregnancy and child marriage. In each country, focus group discussions with young people and parents, in-depth interviews with young people and a variety of other participants, and a household survey with young people (15-24 years) were conducted. We found that (child) marriage was often a response to teenage pregnancy, which was highly prevalent in all study areas. Young people's aspirations to enter adulthood were influenced by their life circumstances. Initiation ceremonies symbolised the transition to adulthood and gave social endorsement to young people to start engaging in (often unprotected) sexual activity. Given the uncertain socio-economic context, resource constraints led families to marry off their daughters; or girls themselves to marry early to relieve the burden on their families, but also to get pregnant as a 'next step' towards adulthood. Transactional sex was common. These intersecting cultural, social and economic contextual factors constrained young women's agency, more as compared to young men. However, young women did manoeuvre within contextual constraints to exercise a degree of agency.

Predictive Analytics Using Machine Learning to Identify ART Clients at Health System Level at Greatest Risk of Treatment Interruption in Mozambique and Nigeria

BACKGROUND

A core objective of HIV/AIDS programming is keeping clients on treatment to improve their health outcomes and to limit spread. Machine learning and artificial intelligence can combine client, temporal, and locational attributes to identify which clients are at greatest risk of loss to follow-up (LTFU) and enable health providers to direct support interventions accordingly.

SETTING

The analysis was part of a project funded by U.S. President's Emergency Plan for AIDS Relief and United States Agency for International Development, Data for Implementation, and applied to data from publicly available sources (health facility data, geospatial data, and satellite imagery) and de-identified electronic medical record data on antiretroviral therapy clients in Nigeria and Mozambique.

METHODS

The project applied binary classification techniques using temporal cross-validation to predict the risk that patients would be LTFU. Classifiers included logistic regression, neural networks, and tree-based models.

RESULTS

Models showed strong predictive power in both settings. In Mozambique, the best-performing model, a Random Forest, achieved an area under the precision-recall curve of 0.65 compared against an underlying LTFU rate of 23%. In Nigeria, the best-performing model, a boosted tree, achieved an area under the precision-recall curve of 0.52 compared against an underlying LTFU rate of 27%.

CONCLUSIONS

Machine-learned models outperformed current classification techniques and showed potential to better direct health worker resources toward patients at greatest risk of LTFU. Moreover, models performed equally across sex and age groups, supporting the model's generalizability and wider application.

Environmentally Just Futures: A Collection of Community-Driven African Environmental Education and Improvement Initiatives

Advocating for healthy environments is a matter of justice. Changes in environments have tremendous impacts on the health of communities, and oftentimes, individuals are unable to safeguard themselves through individual actions alone. Efforts frequently require collective action and are often most effective when led by the communities most impacted. In this spirit, we launched “Vibrations”, an African environment photo essay contest. Through funding and publicity, we aimed to support community-led environmental improvement and education initiatives presently taking place on the continent. We received nearly two dozen submissions and selected eight winners. The winners come from five countries (Ghana, Kenya, Mozambique, Nigeria, and South Africa) and have taken on a range of projects aimed at improving environments across a variety of African regions. Projects included efforts to combat pollution, create environmentally conscious school curricula, utilize clean energy sources, and spread awareness about environmental justice concerns in local communities. It is our hope that this report highlights these transformative community-driven efforts, promotes continued conversations on environmental justice in Africa, and encourages meaningful action via policy changes and collaborations throughout the African continent and beyond.

Leveraging Stakeholder Engagement and Virtual Environments to Develop a Strategy for Implementation of Adolescent Depression Services Integrated Within Primary Care Clinics of Mozambique

Psychiatric disorders are the number one cause of disability in adolescents worldwide. Yet, in low- and middle-income countries (LMIC), where 90% of adolescents reside, mental health services are extremely limited, and the majority do not have access to treatment. Integration of mental health services within primary care of LMICs has been proposed as an efficient and sustainable way to close the adolescent mental health treatment gap. However, there is limited research on how to effectively implement integrated mental health care in LMIC. In the present study, we employed Implementation Mapping to develop a multilevel strategy for integrating adolescent depression services within primary care clinics of Maputo, Mozambique. Both in-person and virtual approaches for Implementation Mapping activities were used to support an international implementation planning partnership and promote the engagement of multilevel stakeholders. We identified determinants to implementation of mental health services for adolescents in LMIC across all levels of the Consolidated Framework for Implementation Research, of which of 25% were unique to adolescent-specific services. Through a series of stakeholder workshops focused on implementation strategy selection, prioritization, and specification, we then developed an implementation plan comprising 33 unique strategies that target determinants at the intervention, patient, provider, policy, and community levels. The implementation plan developed in this study will be evaluated for delivering adolescent depression services in Mozambican primary care and may serve as a model for other low-resource settings.

A high level of antibiotic resistance in Klebsiella and Aeromonas isolates from street water sold in Mozambique, associated with the prevalence of extended-spectrum and AmpC ß-lactamases

This study aims to evaluate the resistance profile and the prevalence of antibiotic resistance genes in 30 isolates of Klebsiella spp. and Aeromonas spp. recovered from water sold in the streets of Maputo. Susceptibility profiles to 15 antibiotics were performed according to Clinical Laboratory Standard Institute guidelines with antibiotic disks on Mueller-Hinton agar plates. Multiplex PCRs were performed targeting 10 ß-lactamase genes, five ESBL (bla_TEM-variants, bla_OXA-variants, Bla_SHV-variants, MCTX-_M Group 1 and Group 9 variants) and five AmpC (ACC variants, FOX variants, MOX variants, CIT variants and DHA variants). The results showed a high prevalence of Klebsiella resistance to ß-lactam antibiotics, such as amoxicillin/clavulanic acid (62.5%), amoxicillin (56.3%), ampicillin (50%), cefoxitin (43.8%), and cefotaxime (43.8%). Aeromonas showed resistance to cefoxitin and ampicillin (71.4%), amoxicillin/clavulanic acid (57.1%) and imipenem (42.9%). ESBL bla_OXA-variants, bla_SVH-variants, MCTX-M Group 1 variants, and MCTX-M Group 9 variants were the most prevalent b-lactam genes, followed by the b-lactams AmpC, ACC variants and FOX variants. It is extremely important to improve waterborne disease control strategies, especially in terms of public awareness of the potential health implications of multidrug-resistant strains of Klebsiella and Aeromonas, which are often neglected.

Perceptions of Community Health Workers (CHW) on barriers and enablers to care for people with psychosis in rural Mozambique: findings of a focus group discussion study using the Capability, Opportunity, Motivation and Behaviour framework (COM-B framework)

BACKGROUND

Psychotic disorders contribute significantly to the global disease burden by causing disability, impaired quality of life, and higher mortality in affected people compared with the general population. In rural settings, where there is limited or no access to healthcare, individuals living with psychotic disorders often seek support from Community Health Workers (CHWs). However, little is known about what CHWs know about psychosis and how they manage such cases. This study aimed to explore the CHWs perception of psychosis and their experiences and beliefs about the factors that might enable or hinder care-taking for patients with psychosis in rural settings in Mozambique.

METHODS

A qualitative study was conducted in rural districts of Maputo Province, a southern region of Mozambique, using six focus group discussions with participation of 79 CHWs. Thematic analysis was used informed by the Capabilities, Opportunities, Motivation and Behaviour framework (COM-B).

RESULTS

Nine primary themes were identified. Overall, CHWs perceived psychosis as treatable medical conditions and held a positive attitude about being part of the care-taking process of patients with psychosis in rural settings. Partnerships with key-stakeholders such as traditional healers, health care workers, and families, were perceived by CHWs as enablers to improve access to care in rural areas. However, stigma, myths, and lack of competencies to treat people with psychosis were perceived by CHWs as barriers for appropriate care.

CONCLUSION

CHWs, with adequate support, could play an important role in the care of patients with psychosis in rural settings, including identifying patients requiring care and referring them to appropriate healthcare professionals, and following up medicated patients with psychosis. Training of CHWs should consider inclusion of basic mental health care competencies.

Human-Centered Design for Public Health Innovation: Codesigning a Multicomponent Intervention to Support Youth Across the HIV Care Continuum in Mozambique

Adolescents and young people represent a growing proportion of people living with HIV (AYAHIV), and there is an urgent need to design, implement, and test interventions that retain AYAHIV in care. Using a human-centered design (HCD) approach, we codesigned CombinADO, an intervention to promote HIV viral suppression and improve antiretroviral therapy (ART) adherence and retention in care among AYAHIV in Nampula, Mozambique. The HCD process involves formative design research with AYAHIV, health care providers, parents/caretakers, and experts in adolescent HIV; synthesis of findings to generate action-oriented insights; ideation and prototyping of intervention components; and a pilot study to assess feasibility, acceptability, and uptake of intervention components.CombinADO promotes ART adherence and retention in care by fostering peer connectedness and belonging, providing accessible medical knowledge, demystifying and destigmatizing HIV, and cultivating a sense of hope among AYAHIV. Successful prototypes included a media campaign to reduce HIV stigma and increase medical literacy; a toolkit to help providers communicate and address the unique needs of AYAHIV clients; peer-support groups to improve medical literacy, empower youth, and provide positive role models for people living with HIV; support groups for parents/caregivers; and discreet pill containers to promote adherence outside the home. In the next phase, the effectiveness of CombinaADO on retention in care, ART adherence, and viral suppression will be evaluated using a cluster-randomized control trial.We demonstrate the utility of using HCD to cocreate a multicomponent intervention to retain AYAHIV in care. We also discuss how the HCD methodology enriches participatory methods and community engagement. This is then illustrated by the youth-driven intervention development of CombinADO by fostering youth empowerment, addressing power imbalances between youth and adult stakeholders, and ensuring that language and content remain adolescent friendly.

The effects of text reminders on the use of family planning services: evidence from a randomised controlled trial in urban Mozambique

Introduction

Reduction of unmet need for contraception is associated with enhanced health outcomes. We conducted a randomised controlled trial in Mozambique analysing the effects of text messages encouraging use of family planning services.

Methods

This trial was conducted within a sample of women served by the Integrated Family Planning Program implemented by Population Services International, in which community health workers provide clinic referrals for family planning services. The evaluation enrolled 5370 women between 20 January and 18 December 2020 who received a referral, reported access to a mobile phone and provided consent. Women were randomly assigned to a treatment group that received a series of text message reminders encouraging them to visit a clinic or to a control arm. An intention-to-treat analysis was conducted to analyse the effect of reminders on the probability of a clinic visit and contraceptive uptake. The final analysis includes 3623 women; 1747 women were lost to follow-up.

Results

Women assigned to receive the text reminders are weakly more likely to visit a clinic (risk difference 2.3 percentage points, p=0.081) and to receive a contraceptive method at a clinic (2.2 percentage points, p=0.091), relative to a base rate of 48.0% and 46.9%, respectively. The effect on clinic visits is larger and statistically significant in the prespecified subsample of women enrolled prior to the COVID-19-related state of emergency (3.2 percentage points, p=0.042).

Conclusion

Evidence from this trial suggests that text message reminders are a promising nudge that increases the probability that women receive contraception.

Qualitative evaluation of enabling factors and barriers to the success and sustainability of national public health institutes in Cambodia, Colombia, Liberia, Mozambique, Nigeria, Rwanda and Zambia

OBJECTIVES

The success of National Public Health Institutes (NPHIs) in low-income and middle-income countries (LMICs) is critical to countries' ability to deliver public health services to their populations and effectively respond to public health emergencies. However, empirical data are limited on factors that promote or are barriers to the sustainability of NPHIs. This evaluation explored stakeholders' perceptions about enabling factors and barriers to the success and sustainability of NPHIs in seven countries where the U.S. Centers for Disease Control and Prevention (CDC) has supported NPHI development and strengthening.

DESIGN

Qualitative study.

SETTING

Cambodia, Colombia, Liberia, Mozambique, Nigeria, Rwanda and Zambia.

PARTICIPANTS

NPHI staff, non-NPHI government staff, and non-governmental and international organisation staff.

METHODS

We conducted semistructured, in-person interviews at a location chosen by the participants in the seven countries. We analysed data using a directed content analysis approach.

RESULTS

We interviewed 43 NPHI staff, 29 non-NPHI government staff and 24 staff from non-governmental and international organisations. Participants identified five enabling factors critical to the success and sustainability of NPHIs: (1) strong leadership, (2) financial autonomy, (3) political commitment and country ownership, (4) strengthening capacity of NPHI staff and (5) forming strategic partnerships. Three themes emerged related to major barriers or threats to the sustainability of NPHIs: (1) reliance on partner funding to maintain key activities, (2) changes in NPHI leadership and (3) staff attrition and turnover.

CONCLUSIONS

Our findings contribute to the scant literature on sustainability of NPHIs in LMICs by identifying essential components of sustainability and types of support needed from various stakeholders. Integrating these components into each step of NPHI development and ensuring sufficient support will be critical to strengthening public health systems and safeguarding their continuity. Our findings offer potential approaches for country leadership to direct efforts to strengthen and sustain NPHIs.

Determinants of immunisation dropout among children under the age of 2 in Zambézia province, Mozambique: a community-based participatory research study using Photovoice

OBJECTIVE

Immunisations are highly impactful, cost-effective public health interventions. However, substantial gaps in complete vaccination coverage persist. We aimed to describe caregivers' immunisation experiences and identify determinants of vaccine dropout.

DESIGN

We used a community-based participatory research approach employing Photovoice, SMS (short messaging service) exchanges and in-depth interviews. A team-based approach was used for thematic analysis. The Increasing Vaccination Model guided the analysis and identification of vaccination facilitators and barriers.

SETTING

This study was conducted in Zambézia province, Mozambique, in Namarroi and Gilé districts, where roughly 19% of children under 2 start but do not complete the recommended vaccination schedule.

PARTICIPANTS

Participants were identified through health facility vaccination records and included caregivers of children aged 25-34 months who were fully vaccinated (n=10) and partially vaccinated (n=22). We also collected data from 12 health workers responsible for delivering immunisations at the selected health facilities.

RESULTS

Four main patterns of barriers leading to dropout emerged: (1) social norms and limited family support place the immunisation burden on mothers; (2) perceived poor quality of health services reduces caregivers' trust in vaccination services; (3) concern about side effects causes vaccine hesitancy; and (4) caregivers hesitate to seek and advocate for vaccination due to power imbalances with health workers. COVID-19 created additional barriers related to social distancing, mask requirements, supply chain challenges and disrupted outreach services. For most caregivers, dropout becomes increasingly likely with compounding barriers. Caregivers of fully-vaccinated children noted facilitators, including accompaniment to health facilities or assistance caring for other children, which enabled them to complete vaccination.

CONCLUSIONS

Overcoming immunisation barriers requires strengthening health systems, including improving logistics to avert vaccine stockouts and building health worker capacity, including empathic communication with caregivers. Consistent and reliable immunisation outreach services could address access challenges and improve immunisation uptake, particularly in distant communities.

Integrating a Transdiagnostic Psychological Intervention Into Routine HIV Care: A Mixed-Methods Evaluation of the Common Elements Treatment Approach in Mozambique

INTRODUCTION

We integrated a transdiagnostic psychological intervention (Common Elements Treatment Approach [CETA]) into routine HIV care in Sofala, Mozambique. This task-shared program screens and treats newly diagnosed HIV+ patients with comorbid mental health symptoms.

METHODS

A mixed-methods evaluation included demographics, intake screening scores, mental health symptoms, and barriers/facilitators to implementation examined through interviews. Multilevel models were used to analyze factors associated with symptom improvement and loss to follow-up (LTFU).

RESULTS

From March 2019 to June 2020, 820 individuals were screened for CETA treatment; 382 (46.6%) showed clinically significant mental health symptoms and attended 1484 CETA sessions. Of CETA patients, 71.5% (n = 273/382) had general mental distress, 7.3% (n = 28) had alcohol abuse/dependence, 12.0% (n = 46) had suicidal ideation, and 3.7% (n = 14) had other violent ideation; 66.2% (n = 253) had experienced at least 1 traumatic event at intake. Mental health symptoms decreased by 74.1% (17.0 to 4.4) after 5 CETA sessions, and 37.4% of patients (n = 143) achieved a ≥50% symptom reduction from intake. LTFU was 29.1% (n = 111), but 59.5% of LTFU patients (n = 66) achieved a ≥50% symptom reduction before LTFU. Facilitators for CETA implementation included readiness for change given the unaddressed burden of mental illness. Barriers included complexity of the intervention and stigma.

CONCLUSIONS

Approximately 45% of newly diagnosed HIV+ individuals in Mozambique have clinically significant mental health symptoms at diagnosis. Integrating CETA into routine HIV platforms has in-context feasibility. Future implementation studies can optimize strategies for patient retention and scale-up.

A pilot to promote early child development within health systems in Mozambique: a qualitative evaluation

Health systems offer unique opportunities for integrating services to promote early child development (ECD). However, there is limited knowledge about the implementation experiences of using health services to target nurturing care and ECD, especially in sub-Saharan Africa. We conducted a qualitative implementation evaluation to assess the delivery, acceptability, perceived changes, and barriers and facilitators associated with a pilot strategy that integrated developmental monitoring, nutritional screening, and early learning and nutrition counseling into the existing health facility, and community-based services for young children in rural Mozambique. We completed individual interviews with caregivers (N = 36), providers (N = 27), and district stakeholders (N = 10), and nine facility observational visits at three primary health facilities in October-November 2020. We analyzed data using thematic content analysis. Results supported fidelity to the intended pilot model and acceptability of nurturing care services. Respondents expressed various program benefits, including strengthened health system capacity and improved knowledge, attitudes, and practices regarding nurturing care and ECD. Government leadership and supportive supervision were key facilitators, whereas health system resource constraints were key barriers. We conclude that health systems are promising platforms for supporting ECD and discuss several programmatic recommendations for enhancing service delivery and maximizing potential impacts on nurturing care and ECD outcomes.

Measuring and valuing broader impacts in public health: Development of a sanitation-related quality of life instrument in Maputo, Mozambique

Two billion people globally lack access to a basic toilet. While improving sanitation reduces infectious disease, toilet users often identify privacy, safety and dignity as more important. However, these outcomes have not been incorporated in sanitation-related economic evaluations. This illustrates the general challenge of outcome measurement and valuation in the economic evaluation of public health interventions, and risks misallocating the US$ 20 billion invested in sanitation in low- and middle-income countries every year. In this study in urban Mozambique, we develop an instrument to measure sanitation-related quality of life (SanQoL). Applying methods from health economics and the capability approach, we develop a descriptive system to measure five attributes identified in prior qualitative research: disgust, health, shame, safety and privacy. Sampling individuals from the intervention and control groups of a sanitation intervention trial, we elicit attribute ranks to value a SanQoL index and assess its validity and reliability. In combination with a measure of time using a sanitation service, SanQoL can quantify incremental benefits in a sanitation-focused cost-effectiveness analysis. After monetary valuation based on willingness to pay, QoL benefits could be summed with health gains in cost-benefit analysis, the most common method in sanitation economic evaluations.

Health-Seeking Behaviors in Mozambique: A Mini-Study of Ethnonursing

In settings where traditional medicine is a crucial part of the healthcare system, providing culturally competent healthcare services is vital to improving patient satisfaction and health outcomes. Therefore, this study sought to gain insight into how cultural beliefs influence health-seeking behaviors (HSBs) among Mozambicans. Participant observation and in-depth interviews (IDIs) were undertaken using the ethnonursing method to investigate beliefs and views that Mozambicans (living in Pemba City) often take into account to meet their health needs. Data were analyzed in accordance with Leininger’s ethnonursing guidelines. Twenty-seven IDIs were carried out with 12 informants from the Makonde and Makuwa tribes. The choice of health service was influenced by perceptions of health and illness through a spiritual lens, belief in supernatural forces, dissatisfaction with and dislike of the public medical system on grounds of having received poor-quality treatment, perceived poor communication skills of health professionals, and trust in the indigenous medical system. This study confirmed the need for health professionals to carefully take cultural influences into consideration when providing care for their patients. We recommend an educational intervention that emphasizes communication skills training for healthcare workers to ensure successful physician/nurse–patient relationships.

Modeling the Influence of Abiotic and Biotic Factors on Spatial and Temporal Fluctuations of Prostephanus truncatus (Coleoptera: Bostrichidae) Populations in Mozambique

The larger grain borer, Prostephanus truncatus (Horn) (Coleoptera: Bostrichidae), is a serious pest of stored maize in Mozambique and in other African countries. This study investigated the influence of abiotic and biotic factors on populations of P. truncatus at four sites over a two-year period (2013-2014) in Mozambique. Fourteen 250 × 250 m quadrants were selected at each site. Plant species diversity, temperature, precipitation, and relative humidity data were recorded. Pheromone-baited Uni-traps were used to monitor P. truncatus inside each quadrant. In addition, plant species were identified using visual observation and measurement of morphological features of leaves and fruits, and quantified, after which the percentage of host plant species of P. truncatus was determined out of all species in each quadrant. Multiple regression analysis and generalized linear models showed that host plant species dominance, maximum and minimum temperature, relative humidity, and rainfall influenced the variations in P. truncatus abundance. The development of these models of P. truncatus flight activity provides a baseline for further studies predicting dispersal and potential areas of invasion by this pest.

Nevirapine hair and plasma concentrations and HIV-1 viral suppression among HIV infected ante-partum and post-partum women attended in a mother and child prevention program in Maputo city, Mozambique

INTRODUCTION

Prevention of mother to child transmission of HIV (PMTCT) is frequently challenged by irregular access to more effective anti-retroviral therapy. Nevirapine single dose (sdNVP), sdNVP+AZT+3TC for MTCT prophylaxis and NVP+ AZT+3TC for treatment and PMTCT were withdrawn due to low genetic resistance barrier and low efficacy. However current PMTCT lines in Mozambique include DTG+3TC+TDF, TDF+3TC+EFV, DTG +ABC+3TC, and AZT + NVP syrup prophylaxis for exposed babies. We assessed NVP hair and plasma concentrations and association with HIV-1RNA suppression among HIV+ ante-partum and post-partum women under PMTCT in Maputo, Mozambique.

METHODS

From December 2013 to November 2014, prospectively were enrolled 200 HIV+ ante-partum women on 200mg nevirapine and zidovudine 300 plus lamivudine 150mg twice daily at least with 3 months treatment and seen again at 24 weeks post-partum. Self-reported pill-taking adherence, NVP concentrations in hair, plasma, hemoglobin, CD4 cell count, HIV-1 RNA load was evaluated. NVP concentration in hair and plasma was analyzed as categorical quartile variable based on better data fit. NVP concentration was set between ≤3.77 ng/ml in plasma and ≤17,20 ng/mg in hair in quartile one to ≥5.36 ng/ml in plasma and ≥53.21 ng/mg in hair in quartile four. Logistic regression models for repeated measures were calculated. Following the World Health Organization (WHO) guidelines we set viral suppression at HIV-1RNA < 1000 c/mL. Outcome was HIV-1 RNA<1000 copies/ml. Predictor was NVP concentration in hair categorized in quartiles.

RESULTS

In total 369 person-visits (median of 1.85) were recorded. Self-reported adherence was 98% (IQR 97-100%) at ante-partum. In 25% person visits, NVP concentrations were within therapeutic levels (3.77 ng/ml to 5.35 ng/ml) in plasma and (17.20 ng/mg to 53.20 ng/mg) in hair. In 50% person visits NVP concentrations were above 5.36 ng/ml in plasm and 53.21 ng/mg in hair. HIV-1 RNA suppression was found in 34.7% of women with two viral loads, one at enrollment and another in post-partum. Odds of HIV-1 RNA suppression in quartile 4, was about 6 times higher than in quartile 1 (p-value = 0.006) for NVP hair concentration and 7 times for NVP plasma concentration (p-value = 0.012).

CONCLUSIONS

The study results alert for potential low efficacy of current PMTCT drug regimens in use in Mozambique. Affordable means for individual monitoring adherence, ART plasma and hair levels, drug resistant and HIV-1 RNA levels monitoring are recommended for prompt identification of inadequate drug regimens exposure patterns and adjust accordingly.
