Abstract Background Seroprevalence of SARS Cov-2 provides a good indication of the extent of exposure and spread in the population, as well as those likely to benefit from a vaccine candidate. To date, there is no published or ongoing systematic review on the seroprevalence of COVID-19 in Low- and Middle-Income Countries (LMICs). This systematic review and meta-analysis will estimate SARS Cov-2 seroprevalence and the risk factors for SARS Cov-2 infection in LMICs.Methods We will search PubMed, EMBASE, WHO COVID-19 Global research database, Google Scholar, the African Journals Online, LILAC, HINARI, medRxiv, bioRxiv and Cochrane Library for potentially useful studies on seroprevalence of COVID-19 in LMICs from December 2019 to December 2020 without language restriction. Two authors will independently screen all the articles, select studies based on pre-specified eligibility criteria and extract data using a pre-tested data extraction form. Any disagreements will be resolved through discussion between the authors. The pooled seroprevalence of SARS CoV-2 for people from LMICs will be calculated. Random effects model will be used in case of substantial heterogeneity in the included studies, otherwise fixed-effect model will be used. A planned subgroup, sensitivity and meta-regression analyses will be performed. For comparative studies, the analyses will be performed using Review Manager v 5.4; otherwise, STATA 16 will be used. All effect estimates will be presented with their confidence intervals.Discussion The study will explore and systematically review empirical evidence on SARS Cov-2 seroprevalence in LMICs, and to assess the risk factors for SARS Cov-2 infection in Low Middle Income Countries in the context of rolling out vaccines in these countries. Finally, explore risk classifications to help with the rolling out of vaccines in LMICs.Systematic review registration: The protocol for this review has been registered in PROSPERO (CRD422020221548).

Abstract Background: Cotton workers are exposed to various hazards in the textile industry that might result in different ailments including hypertension (HTN). However, few attempts have been made to systematically review the prevalence of hypertension and its risk factor among cotton textile workers in low-and-middle-income countries (LMICs). The objective of this study will be to evaluate the prevalence of hypertension and its risk factors among adult cotton textile workers in low- and middle-income countries. Methods: We designed and registered a study protocol for a systematic review of descriptive epidemiology data. We will include observational studies (e.g. cross-sectional, cohort, surveys) on the epidemiology of hypertension among adult cotton textile workers in low- and middle-income countries. The primary outcome will be the prevalence of hypertension. Secondary outcomes will be the prevalence of risk factors of hypertension. Literature searches will be conducted in multiple electronic databases (from January 2000 onwards), including PubMed/MEDLINE, CINAHL, Science Direct, and Cochrane Library. Grey literature will be identified through searching conference abstracts, thesis dissertations and public repositories. Two investigators will independently screen all citations, full-text articles, and abstract data. The study methodological quality (or bias) will be appraised using an appropriate tool. If feasible, we will conduct random effects meta-analysis. Additional analyses will be conducted to explore the potential sources of heterogeneity (e.g. age, gender, years of service, textile department). Discussion: This review will highlight the proportion of hypertension along with its risk factor among cotton textile workers in LMICs. Given that, some of the factors can be prevented in this high-risk population, we will call on health, experts to prioritize policies and commission and conduct programs to support the improvement in their health. This systematic review will identify, evaluate and integrate evidence on the prevalence and risk factors of hypertension among adult cotton textile workers in low- and middle-income countries. Our findings will be made publicly available in a repository and published in a peer-reviewed journalSystematic Review Registration: The present protocol has been registered within the PROSPERO database (registration ID: CRD42020167175)

Background: Self-harm (defined here as an act of intentionally causing harm to own self, irrespective of the type, motive or suicidal intent) is one of the strongest antecedents of suicide in youth. While there have been a number of studies of youth self-harm in low- and middle-income countries (LMICs), there is currently no systematic review of studies of prevalence rates and risk and protective factors. Aim: To systematically review the evidence relating to the prevalence rates and forms of self-harm in youth in LMICs and its relationship to family economic status, family functioning, relationship with the peer group, social relationships and academic performance. Methods: Electronic searches of three databases, MEDLINE, PsycINFO and Scopus, were performed. In total, 27 school-, community- and hospital-based studies evaluating self-harm in LMICs with youth focus (with participants between 12 and 25 years) were included. Results: The self-harm was divided into suicidal and non-suicidal depending on the nature of self-harm. The 12-month prevalence rates of non-suicidal self-harm varied from 15.5% to 31.3%, and the range of suicidal behaviour rates was from 3.2% to 4.7%. Banging and hitting were the most common in the community-based studies, followed by cutting, scratching and wound picking. Self-poisoning with pesticides was most commonly reported in hospital-based studies. Risk factors for self-harm were family conflict, peer groups with members indulging in self-harm, truancy and school absenteeism. Protective factors were having an understanding family, having friends and higher school competence. Risk factors for suicidal thoughts and attempts were lack of close friends and history of suicide by a friend. Conclusion: The 12-month prevalence rates of youth self-harm in LMICs are comparable to high-income countries (HICs). The profile of risk and protective factors suggests that family-based interventions could be useful in treatment and prevention. Future studies should aim for greater consistency in assessment methods and the constructs under evaluation.
