Introduction Multiple micronutrient supplementation (MMS) during pregnancy has a greater potential for reducing the risk of low birth weight (LBW) compared with the standard iron–folic acid supplementation. WHO recently included MMS on their Essential Medicines List. The Social Marketing Company (SMC) in Bangladesh is implementing a countrywide, market-based roll-out of MMS to pregnant women. We aimed to evaluate the implementation of the supplementation programme and its impact on reducing LBW.Methods and analysis A two-arm, quasi-experimental and mixed-methods evaluation design will be used to evaluate the impact of this 36-month roll-out of MMS. In the intervention areas, pregnant women will purchase MMS products from the SMC’s pharmacy networks. Pregnant women in comparison areas will not be exposed to this product until the end of the study. We will collect 4500 pregnant women’s data on anthropometric, socioeconomic, nutrition-related and relevant programme indicators during recruitment and bimonthly follow-up until the end of their pregnancy. We will measure children’s birth weight within 72 hours of birth and evaluate the changes in LBW prevalence. We will observe market-based MMS service delivery-related conditions of the pharmacies and the quality of the provider’s service delivery. Concurrently, we will carry out a process evaluation to appraise the programme activities and recommend course correction. Cluster-adjusted multivariable logistic regression or log-binomial regression analysis of quantitative outcome data will be performed. For qualitative data, we will follow a thematic analysis approach. We will consolidate our study findings by triangulating the data derived from different methods.Ethics and dissemination This study received ethical approval from the institutional review board of icddr,b (PR number 21001). We will recruit eligible participants after obtaining their informed written/verbal consent (and assent where needed) with full disclosure about the study. The results will be disseminated through peer-reviewed publications and conference presentations.Trial registration number NCT05108454.

Introduction Caring for stroke survivors creates high levels of care burden among family caregivers. Previous initiatives at alleviating the care burden have been unsuccessful. The proposed study aims to evaluate the effect of a tailored multidimensional intervention on the care burden among family caregivers of stroke survivors. Based on the perceived needs of family caregivers, this intervention takes into account scientific recommendations to combine three different approaches: skill-building, psychoeducation and peer support.Methods and analysis Using a prospective, randomised, open-label, parallel-group design, 110 family caregivers will be enrolled from Dakahlia Governorate, Egypt between December 2019 and May 2020, and randomly assigned to either the intervention group or the control group. The tailored multidimensional intervention will be administered for 6 months, including three home visits, six home-based telephone calls and one peer support session. The primary outcome is the care burden as measured using the Zarit Burden Interview. Secondary outcomes include changes in the family caregivers’ perceived needs (Family Needs Questionnaire-Revised), coping strategies (Brief-Coping Orientation to Problems Experienced) and quality of life (WHO Quality of Life-BREF). Outcomes evaluation will be conducted at baseline (T0), month 3 (T1) and month 6 (T2). Independent t-test will be performed to compare the mean values of study variables between the two groups at both T1 and T2. After adjusting for confounding variables, analysis of covariance will be used to assess the effect of the intervention. In addition, repeated measures analysis of variance will be conducted to assess changes in effect over time.Ethics and dissemination This study was approved by the Research Ethics Committee of the Faculty of Nursing, Mansoura University, Mansoura, Egypt (P.0195). The results will be published in a scientific peer-reviewed journal, and findings will be disseminated at the local and international levels.Trial registration number NCT04211662.
