Antiretroviral therapy clinic attendance among children aged 0-14 years in Kahama district, Tanzania: a cross-sectional study
Background: Efforts made to scale up care and treatment for HIV in Tanzania have started to pay off. The number of people living with HIV (PLHIV) who are on antiretroviral therapy (ART) has massively increased owing to an increase in investment made. However, this is not reflected in all populations, especially children living with HIV. This study, therefore, aims to determine the magnitude and factors associated with ART uptake among children living with HIV in Kahama district, Tanzania.Methods: This cross-sectional study was conducted among pairs of children aged 0-14 years and their caregivers. A total of 423 randomly selected caregivers of HIV-positive children were interviewed using a structured questionnaire. The outcome variable was ART uptake while independent variables constituted of socio-demographic, health facility, and systemic factors.Results: A total of 132 (31%) of all caregivers reported to have missed at least one clinic visit for their children during a period of three months before the survey. Of them, one in four missed at least two clinics. Caregivers cited factors such as lack of transport fare and distance to the health facility as barriers to attend the planned clinics. After adjusting for the important confounders and other covariates, factors associated with ART uptake were being divorced/widowed (AOR= 0.57, 95% CI; 0.33-0.97) and having primary education or more (AOR 0.30, 95% CI 0.11-0, 82).Conclusion: One in every three HIV-positive children miss their scheduled routine ART clinics in Kahama, Shinyanga. Tailored interventions should target caregivers of such children who are divorced or widowed and those with low or no education while addressing distance and transportation challenges in this and other areas with similar contexts.
Short inter-pregnancy interval: why is it still high among women in Dar es Salaam?
Introduction: in Tanzania, for the past decade, there has been a rising trend of women with short inter-pregnancy interval (IPI) (16% to 19%). Short IPI is associated with poor maternal and neonatal outcomes. We aimed to determine the factors associated with short IPI among women attending antenatal clinic (ANC) at Mnazi Mmoja Hospital, Dar es Salaam, Tanzania.
Methods: a cross-sectional study was conducted in September 2018 at Mnazi Mmoja hospital among women receiving ante-natal care. A total of 530 women were included in the analysis. Analysis was conducted through SPSS version 24 computer program using descriptive analyses to determine the IPI and characteristics thereof, and logistic regression analysis to examine factors associated with IPI among pregnant women. Associations with a p-value < 0.05 were considered statistically significant.
Results: twenty-two percent of the women attending ANC in Mnazi Mmoja hospital had short IPI. Short IPI was associated with young(<25years) age (AOR=2.67, 95% CI=1.23-5.79); non-use of a contraceptive method (AOR=2.05, 95%CI=1.22-3.45); breastfeeding for less than 6 months (AOR=3.45,95% CI=1.17-10.13) and having an antecedent dead child at the time of index conception (AOR=3.38,95% CI=1.15-9.93).
Conclusion: about 1 in every 5 women attending ANC in Dar es Salaam had a short IPI. Addressing short IPI will complement the government´s efforts to improve maternal indicators in Tanzania and areas with similar contexts. Such efforts should emphasize in adherence to recommended infant feeding practices, women at a younger reproductive age group, those with a history of pregnancy loss, and strengthening contraception use among women of reproductive age
Towards Eliminating Malaria in High Endemic Countries: The Roles of Community Health Workers and Related Cadres and their Challenges in Integrated Community Case Management for Malaria: A Systematic Review.
Human resource for health crisis has impaired global efforts against malaria in highly endemic countries. To address this, the World Health Organization (WHO) recommended scaling-up of community health workers (CHWs) and related cadres owing to their documented success in malaria and other disease prevention and management. Evidence is inconsistent on the roles and challenges they encounter in malaria interventions. This systematic review aims to summarize evidence on roles and challenges of CHWs and related cadres in integrated community case management for malaria (iCCM). This systematic review retrieved evidence from PubMed, CINAHL, ISI Web of Knowledge, and WHO regional databases. Terms extracted from the Boolean phrase used for PubMed were also used in other databases. The review included studies with Randomized Control Trial, Quasi-experimental, Pre-post interventional, Longitudinal and cohort, Cross-sectional, Case study, and Secondary data analysis. Because of heterogeneity, only narrative synthesis was conducted for this review. A total of 66 articles were eligible for analysis out of 1380 studies retrieved. CHWs and related cadre roles in malaria interventions included: malaria case management, prevention including health surveillance and health promotion specific to malaria. Despite their documented success, CHWs and related cadres succumb to health system challenges. These are poor and unsustainable finance for iCCM, workforce related challenges, lack of and unsustainable supply of medicines and diagnostics, lack of information and research, service delivery and leadership challenges. Community health workers and related cadres had important preventive, case management and promotive roles in malaria interventions. To enable their effective integration into the health systems, the identified challenges should be addressed. They include: introducing sustainable financing on iCCM programmes, tailoring their training to address the identified gaps, improving sustainable supply chain management of malaria drugs and diagnostics, and addressing regulatory challenges in the local contexts

Nutrition Training Improves Health Workers' Nutrition Knowledge and Competence to Manage Child Undernutrition: A Systematic Review.
Medical and nursing education lack adequate practical nutrition training to fit the clinical reality that health workers face in their practices. Such a deficit creates health workers with poor nutrition knowledge and child undernutrition management practices. In-service nutrition training can help to fill this gap. However, no systematic review has examined its collective effectiveness. We thus conducted this study to examine the effectiveness of in-service nutrition training on health workers' nutrition knowledge, counseling skills, and child undernutrition management practices. We conducted a literature search on nutrition interventions from PubMed/MEDLINE, CINAHL, EMBASE, ISI Web of Knowledge, and World Health Organization regional databases. The outcome variables were nutrition knowledge, nutrition-counseling skills, and undernutrition management practices of health workers. Due to heterogeneity, we conducted only descriptive analyses. Out of 3910 retrieved articles, 25 were selected as eligible for the final analysis. A total of 18 studies evaluated health workers' nutrition knowledge and showed improvement after training. A total of 12 studies with nutrition counseling as the outcome variable also showed improvement among the trained health workers. Sixteen studies evaluated health workers' child undernutrition management practices. In all such studies, child undernutrition management practices and competence of health workers improved after the nutrition training intervention. In-service nutrition training improves quality of health workers by rendering them more knowledge and competence to manage nutrition-related conditions, especially child undernutrition. In-service nutrition training interventions can help to fill the gap created by the lack of adequate nutrition training in the existing medical and nursing education system. In this way, steps can be taken toward improving the overall nutritional status of the child population
Impaired fasting glucose levels among perinatally HIV-infected adolescents and youths in Dar es Salaam, Tanzania
ObjectiveThis study assessed impaired fasting glucose and associated factors among perinatally HIV-infected adolescents and youths in Dar es salaam Tanzania.BackgroundImpaired fasting glucose is a marker of heightened risk for developing type 2 diabetes among perinatally HIV-infected individuals. Therefore, identifying individuals at this stage is crucial to enable early intervention. Therefore, we assessed impaired fasting glucose (IFG) and associated factors among perinatally HIV-infected population in Dar es salaam Tanzania. MethodsA cross-sectional study was conducted among 152 adolescents and youth attending HIV clinic at Muhimbili National Hospital and Infectious Disease Centre from July to August 2020. Fasting blood glucose (>8 hours) was measured using one-touch selects LifeScan, CA, USA. We also examined C-Reactive Protein and interleukin-6 inflammatory biomarkers in relation to impaired fasting glucose (IFG). Associations between categorical variables were explored using Chi-square, and poison regression with robust variance was used to calculate the prevalence ratios.ResultsOf the 152 participants, the majority were male (n=83[54.6%]), and the median age was 15(14-18) years. Overweight or obesity was prevalent in 16.4%, while more than one in ten (13.2%) had high blood pressure (≥149/90mmHg). All participants were on antiretroviral therapy (ART); 46% had used medication for over ten years, and about one in three had poor medication adherence. Among the recruited participants, 29% had impaired fasting glucose. The odds of IFG were two times higher in males compared to females (PR, 2.07, 95% CI 1.19 -3.59 p=0.001). Moreover, we found with every increase of Interleukin 6 biomarker there was a 1.01 probability increase of impaired fasting glucose (PR, 1.01, 95% CI 1.00 – 1.02 p=0.003).ConclusionAbout one in three perinatally HIV-infected youths had impaired fasting glucose in Dar es Salaam, Tanzania, with males bearing the biggest brunt. Moreover, with every increase of 1.101 of the probability of having IFG increased. This calls for urgent measures to interrupt the progression to diabetes disease and prevent the dual burden of disease for this uniquely challenged population
Improving communication about HIV prevention among people living with HIV and their at-risk social network members in Dar es Salaam, Tanzania.
Although a number of HIV prevention programs have been implemented, such as mass media campaigns, high rates of unprotected and concurrent sexual partnerships, as well as low uptake HIV testing and limited HIV knowledge, persist in Tanzania. We examined the effect and predicting factors of HIV prevention communication among people living with HIV (PLH) exposed to NAMWEZA intervention, and their at-risk social network members (NMs) Quantitative data were collected from 326 participants at baseline and 24 months of follow-up. In-depth interviews with 20 PLH were conducted at follow-up. Results indicated specific communication about condom use and HIV testing increased; (mean increase of 0.28 (SD = 0.14) scores, P = 0.012 and 0.42 (SD = 0.11) scores, p < 0.001 respectively while general discussion about protecting other people from HIV did not change significantly; mean increase was 0.01 scores (SD = 0.005), p = 0.890. Positive predictors of communication included being single; OR = 1.10, p = 0.01, female; OR = 1.15, p = 0.03, aged 30 years or older; OR = 1.23, p < 0.01, HIV knowledge, dose of NAMWEZA participation; OR = 1.01, p < 0.001, and high self-efficacy for condom use; OR = 1.4, p < 0.001. Stigma demonstrated a significant but negative association with communication for condom use; OR = 1.01, p < 0.01.Qualitative data reflected perceived possession of more individual skills and ability to address some personal/cultural obstacles to communicating about HIV prevention including those observed in the quantitative data. NAMWEZA improved communication about HIV prevention among PLH with their at-risk-NMs. The approach is a promising complement to media campaigns in similar populations. Future research and program evaluation efforts should explore how communities perceive and communicate about protecting others from HIV
Experiential Learning and Mentorship in Global Health Leadership Programs: Capturing Lessons from Across the Globe.
OBJECTIVES: The changing global landscape of disease and public health crises, such as the current COVID-19 pandemic, call for a new generation of global health leaders. As global health leadership programs evolve, many have incorporated experiential learning and mentoring (ELM) components into their structure. However, there has been incomplete consideration on how ELM activities are deployed, what challenges they face and how programs adapt to meet those challenges. This paper builds on the co-authors' experiences as trainees, trainers, organizers and evaluators of six global health leadership programs to reflect on lessons learned regarding ELM. We also consider ethics, technology, gender, age and framing that influence how ELM activities are developed and implemented. FINDINGS: Despite the diverse origins and funding of these programs, all six are focused on training participants from low- and middle-income countries drawing on a diversity of professions. Each program uses mixed didactic approaches, practice-based placements, competency and skills-driven curricula, and mentorship via various modalities. Main metrics for success include development of trainee networks, acquisition of skills and formation of relationships; programs that included research training had specific research metrics as well. Common challenges the programs face include ensuring clarity of expectations of all participants and mentors; maintaining connection among trainees; meeting the needs of trainee cohorts with different skill sets and starting points; and ensuring trainee cohorts capture age, gender and other forms of diversity. CONCLUSIONS: ELM activities for global health leadership are proving even more critical now as the importance of effective individual leaders in responding to crises becomes evident. Future efforts for ELM in global health leadership should emphasize local adaptation and sustainability. Practice-based learning and established mentoring relationships provide the building blocks for competent leaders to navigate complex dynamics with the flexibility and conscientiousness needed to improve the health of global populations. Key Takeaways: Experiential learning and mentorship activities within global health leadership programs provide the hands-on practice and support that the next generation of global health leaders need to address the health challenges of our times.Six global health leadership programs with experiential learning and mentorship components are showcased to highlight differences and similarities in their approaches and capture a broad picture of achievements that can help inform future programs.Emphasis on inter-professional training, mixed-learning approaches and mentorship modalities were common across programs. Both individual capacity building and development of trainees' professional networks were seen as critical, reflecting the value of inter-personal connections for long-term leadership success.During program design, future programs should recognize the "frame" within which the program will be incorporated and intentionally address diversity-in all its forms-during recruitment as well as consider North-South ethics, leadership roles, hierarchies and transition plans
Undernutrition among HIV-positive children in Dar es Salaam, Tanzania: antiretroviral therapy alone is not enough
BackgroundThe prevalence of HIV/AIDS has exacerbated the impact of childhood undernutrition in many developing countries, including Tanzania. Even with the provision of antiretroviral therapy, undernutrition among HIV-positive children remains a serious problem. Most studies to examine risk factors for undernutrition have been limited to the general population and ART-naive HIV-positive children, making it difficult to generalize findings to ART-treated HIV-positive children. The objectives of this study were thus to compare the proportions of undernutrition among ART-treated HIV-positive and HIV-negative children and to examine factors associated with undernutrition among ART-treated HIV-positive children in Dar es Salaam, Tanzania.MethodsFrom September to October 2010, we conducted a cross-sectional survey among 213 ART-treated HIV-positive and 202 HIV-negative children in Dar es Salaam, Tanzania. We measured the children\u27s anthropometrics, socio-demographic factors, food security, dietary habits, diarrhea episodes, economic status, and HIV clinical stage. Data were analyzed using both univariate and multivariate methods.ResultsART-treated HIV-positive children had higher rates of undernutrition than their HIV-negative counterparts. Among the ART-treated HIV-positive children, 78 (36.6%) were stunted, 47 (22.1%) were underweight, and 29 (13.6%) were wasted. Households of ART-treated HIV-positive children exhibited lower economic status, lower levels of education, and higher percentages of unmarried caregivers with higher unemployment rates. Food insecurity was prevalent in over half of ART-treated HIV-positive children\u27s households. Furthermore, ART-treated HIV-positive children were more likely to be orphaned, to be fed less frequently, and to have lower body weight at birth compared to HIV-negative children.In the multivariate analysis, child\u27s HIV-positive status was associated with being underweight (AOR = 4.61, 95% CI 1.38-15.36 P = 0.013) and wasting (AOR = 9.62, 95% CI 1.72-54.02, P = 0.010) but not with stunting (AOR = 0.68, 95% CI 0.26-1.77, P = 0.428). Important factors associated with underweight status among ART-treated HIV-positive children included hunger (AOR = 9.90, P = 0.022), feeding frequency (AOR = 0.02, p \u3c 0.001), and low birth weight (AOR = 5.13, P = 0.039). Factors associated with wasting among ART-treated HIV-positive children were diarrhea (AOR = 22.49, P = 0.001) and feeding frequency (AOR = 0.03, p \u3c 0.001).ConclusionHIV/AIDS is associated with an increased burden of child underweight status and wasting, even among ART-treated children, in Dar es Salaam, Tanzania. In addition to increasing coverage of ART among HIV-positive children, interventions to ameliorate poor nutrition status may be necessary in this and similar settings. Such interventions should aim at promoting adequate feeding patterns, as well as preventing and treating diarrhea
Community-based interventions targeting multiple forms of malnutrition among adolescents in low-income and middle-income countries:protocol for a scoping review
Background:Adolescent malnutrition is a significant public health challenge in low-income and middle-income countries (LMICs), with long-term consequences for health and development. Community-based interventions have the potential to address multiple forms of malnutrition and improve the health outcomes of adolescents. However, there is a limited understanding of the content, implementation and effectiveness of these interventions. This scoping review aims to synthesise evidence on community-based interventions targeting multiple forms of malnutrition among adolescents in LMICs and describe their effects on nutrition and health. Methods and analysis:A comprehensive search strategy will be implemented in multiple databases including MEDLINE (through PubMed), Embase, CENTRAL (through Cochrane Library) and grey literature, covering the period from 1 January 2000 to 14 July 2023. We will follow the Participants, Concept and Context model to design the search strategy. The inclusion criteria encompass randomised controlled trials and quasi-experimental studies focusing on adolescents aged 10–19 years. Various types of interventions, such as micronutrient supplementation, nutrition education, feeding interventions, physical activity and community environment interventions, will be considered. Two reviewers will perform data extraction independently, and, where relevant, risk of bias assessment will be conducted using standard Cochrane risk-of-bias tools. We will follow the PRISMA Extension for Scoping Reviews checklist while reporting results. Ethics and dissemination:The scope of this scoping review is restricted to publicly accessible databases that do not require prior ethical approval for access. The findings of this review will be shared through publications in peer-reviewed journals, and presentations at international and regional conferences and stakeholder meetings in LMICs.</p
