Impacts of school feeding on educational and health outcomes of school-age children and adolescents in low- and middle-income countries: A systematic review and meta-analysis

Abstract Background Biological changes underlying the sexual and reproductive maturation of school-age children are linked with various sexual and reproductive health and rights risks. SRHR risks are predictors of poor SRHR outcomes, such as poor knowledge of sexually transmitted diseases and early sexual initiation occurring predominantly among school-age children. The aim of this proposed review, therefore, is to identify educational interventions that have proven to be effective in promoting or supporting the sexual and reproductive health and rights of school-aged children in low- and middle-income countries. Methods A systematic review of studies on the strategies promoting the SRHR of school-aged children shall be conducted. Electronic searches will be conducted from January 2000 onwards on the following databases: MEDLINE(R) ALL (Ovid), Embase (Ovid), CINAHL (EBSCOHost), APA PsycInfo (Ovid), ERIC (Ovid), Cochrane Central Register of Controlled Trials (Ovid), Education Source (EBSCOHost), Web of Science (Clarivate Analytics), SciELO Citation Index (Clarivate Analytics), Global Health (Ovid), and Sociological Abstract (Proquest). Studies eligible for inclusion will be randomized control trials (RCTs), non-randomized trials, quasi-experimental studies (e.g., pre-post tests), and observational studies (cross-sectional and cohort studies). Peer-reviewed studies published in English and/or French and involving school-aged children 5–10 years old will be included. The primary outcomes of interest will include knowledge, awareness, or attitudes about SRHR topics. The secondary outcomes of interest will include sexual and reproductive behaviors. Two reviewers will independently screen all citations, abstract data, and full-text articles, and the methodological quality of each study will be appraised using JBI critical appraisal tools. A narrative synthesis of extracted data will be conducted. Discussion The systematic review will synthesize the evidence on existing educational interventions targeting SRHR outcomes of school-aged children in low- and middle-income countries. It will identify which interventions have proven to be effective, and which interventions have not proven to be effective in promoting or supporting their SRHR. Review findings will provide a useful reference for policy-makers, program developers, global health leaders, and decision makers who wish to support the SRHR of school-age children. Systematic review registration The protocol has been registered at the International Prospective Register of Systematic Reviews (PROSPERO CRD42020173158).

Abstract Background Metabolic syndrome (MetS) is a clustering of cardiovascular risk factors, which is rising in the low and middle income countries (LMICs). There are various studies with inconsistent findings that are inconclusive for policy makers and program planners. Thus, this systematic review and meta-analysis aimed at estimating the pooled prevalence of MetS and its components in LMICs. Methods Electronic searches were conducted in international databases including PubMed, Web of Science, EMBASE (Elsevier), Scopus, CINAHL (EBSCOhost), Science direct (Elsevier), Food Science and Technology Abstracts (FSTA), Global Health and Medline, and other sources (World Cat, Google Scholar, and Google). The pooled estimates were computed in the random effect model. The pooled prevalence was computed using the three diagnostic methods (IDF, ATP III and de Ferranti). Publication bias was verified using funnel plot and Egger’s regression test. Subgroup and sensitivity analysis were performed to identify the possible sources of heterogeneity among the included studies. Result In this study, 142,142 children and adolescents from 76 eligible articles were included to compute the pooled prevalence of MetS and its components in LMCIs. MeTs among overweight and obese population was computed from 20 articles with the pooled prevalence of 24.09%, 36.5%, and 56.32% in IDF, ATP III and de Ferranti criteria, respectively. Similarly, a total of 56 articles were eligible to compute the pooled prevalence of MetS in the general population of children and adolescents. Hence, Mets was found in 3.98% (IDF), 6.71% (ATP III) and 8.91% (de Ferranti) of study subjects. Regarding the components of MetS, abdominal obesity was the major component in overweight and obese population and low HDL-C was the most common component in the general population. This study also revealed that males were highly affected by MetS than females. Conclusion This study illustrates that MetS among children and adolescents is an emerging public health challenge in LMICs, where the prevalence of obesity is on the move. Preventive strategies such as community and school based intervention need to be designed. Promoting physical activities and healthy eating behaviors could avert this problem.
