Introduction The disease burden caused by type 2 diabetes mellitus is a prime public health concern. The prevalence and rate of deaths from diabetes mellitus in low- and middle-income countries (LMICs) are higher than the high-income countries. Increased physical activity and a balanced diet are essential and successful measures to prevent the onset of diabetes mellitus. This systematic review aims to explore the available non-pharmacological approaches for the prevention of type 2 diabetes mellitus in LMICs. Methods and analysis Six online databases will be explored to get related randomized controlled trials (RCTs) published in English from inception to September 2020, and two coders will independently screen, identify studies, extract data, and assess the risk of bias in each article. The searched articles will be included by applying specific inclusion and exclusion criteria. Joanna Briggs Institute’s tool for RCTs will be used for appraising the trials critically. Narrative synthesis and pooled effect of the interventions will be demonstrated. A meta-analysis will be conducted using the random-effects model if assumptions are fulfilled. Discussion This review is an attempt to explore the available non-pharmacological approaches for the prevention of type 2 diabetes mellitus in LMICs. Findings from the review will highlight effective non-pharmacological measures for the prevention of type 2 diabetes mellitus to guide policy for future strategies. Systematic review registration The review protocol has been registered (CRD42020191507).

ObjectiveDiabetes poses serious health threats and economic burdens to patients, especially in low-income and middle-income countries (LMICs). This systematic review searches for non-pharmacological interventions for the prevention of type-2 diabetes mellitus (T2DM) among patients who are non-diabetic and pre-diabetic from LMICs.SettingsLMICs.ParticipantsAdult population aged over 18 years without having diabetes.Primary and secondary outcomesPrimary outcome is to measure the change in the incidence of T2DM. The secondary outcome is to measure changes in glycated haemoglobin (HbA1c) level, weight/body mass index (BMI), fasting glucose level and 2-hour glucose from baseline of the included randomised controlled trials.MethodsThis review has been conducted following the standard systematic review guidelines. A total of six electronic databases including MEDLINE, Embase, the Cochrane Library, Web of Science, ClinicalTrials.gov and International Clinical Trials Registry Platform were searched in February 2021 using a comprehensive search strategy.Two sets of independent reviewers performed screening, risk of bias (ROB) assessment using the Cochrane ROB tool and data extraction. Narrative coalescence of selected articles was demonstrated using tables. No meta-analysis was performed due to the lack of homogenous intervention strategies and study settings.ResultA total of five studies were included for the review with a combined population of 1734 from three countries. Three of the studies showed a significant reduction in T2DM incidence after the intervention of physical training and dietary modifications. Four of the studies also demonstrated a significant reduction of different secondary outcomes like weight, BMI, fasting and 2-hour plasma glucose and HbA1c. All the studies demonstrated a low ROB in most of the bias assessment domains with some unclear results in allocation concealments.ConclusionsEmphasising non-pharmacological interventions for T2DM prevention can improve health outcomes and lessen the economic burdens, which will be of paramount importance in LMICs.Systematic review registration numberCRD42020191507

Background: South Asia is facing the challenges of non-communicable diseases (NCDs) which are getting doubled due to the low quality of care (QoC) around NCD services. This systematic rapid review aims to unpack available approaches to establish the quality of care around NCD services and the impact of those approaches to reduce NCD burden in South Asian countries. Methods: Three electronic databases (Medline, Embase, and the Cochrane Library) were searched. Studies published from 1st January 1990 to 31st December 2020 were included. Studies written in English in the South Asian context following any research design about four major NCDs (cancer, diabetes, cardiovascular disease, chronic respiratory disease), and interventions to achieve QoC were included. Data extraction was done using a pre-specified form. A narrative synthesis was conducted for analyzing the extracted information. This systematic rapid review is registered in PROSPERO (International prospective register of systematic reviews) - CRD42020157401.Results: Among 829 identified studies 13 were included in the review for in-depth analysis. Most of the studies focused on cancer followed by diabetes and cardiovascular disease. Community and clinic-based screening, NCD care education, NCD specialized corner or hospital, and a follow-up system ensure patient satisfaction, accessibility, early detection, timely referral, and help to reduce disease severity, mortality rate, and incidence of the new disease.Conclusions: The effective interventions for improving QoC around NCD services can be scaled up in different settings in South Asia to reduce the burden of NCDs.

Background: Although Bangladesh has made significant improvements in maternal, neonatal, and child health, the disparity between rich and poor remains a matter for concern. Objective: The study aimed to increase coverage of women in seeking skilled maternal healthcare services while minimizing inequity gap among different socioeconomic groups. Methods: icddr, b implemented an integrated maternal and neonatal health (MNH) intervention between 2009 and 2012, in Shahjadpur sub-district of Shirajganj district, Bangladesh. The study was pre- and post-test in design for evaluation including baseline and endline surveys. The baseline and endline surveys were conducted among 3158 and 3540 recently delivered mothers respectively. Asset index derived from household assets using principal component analysis was categorized into five ordinal categories, i.e. Poor, Less poor, Middle, Upper middle, Rich. Inequity in maternal healthcare utilization was calculated for the baseline and endline periods using rich-to-poor ratio and the concentration index. Result: Mean age of mothers were 23.5 and 24.3 years in baseline and endline, respectively. Reduction in rich-poor ratio was quite large in utilization of skilled 4+ antenatal care (ANC) (2.4:1 to 1.1:1), childbirth (1.7:1 to 1.0:1), and postnatal care (PNC) (2.5:1 to 1.0:1) from trained providers between these two surveys. The concentration indices (CI) in endline for skilled 4+ ANC (CI: 0.220 and 0.013), delivery (CI: 0.161 and -0.021), and PNC (CI: 0.197 and -0.004) were found to be lower than the indices in baseline period respectively. Conclusion: The MNH intervention was successful in reducing inequity in receiving skilled 4+ ANC, delivery, and PNC in rural Bangladesh. Improvements in maternal healthcare utilizations by poor mothers would be influenced by the properly designed and integrated demand- and supply-side MNH interventions package.
