  El objetivo de este estudio fue conocer qué investigaciones de carácter longitudinal se han llevado a cabo que hayan analizado variables relacionadas con el sobrepeso, la obesidad y el sedentarismo en edad escolar, y qué datos se pueden extraer de las mismas. Se revisaron las siguientes bases de datos: MEDLINE (PubMed), Scopus, SportDiscus y WOS (Web of Science). Dicha revisión fue realizada siguiendo el modelo PICOs, y a partir de él, se constituyó el protocolo de búsqueda utilizando términos que definan o representen a niños y jóvenes en edad escolar, que puedan presentar o no sobrepeso u obesidad y sedentarismo. Siguiendo el procedimiento Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA), de los 2237 estudios encontrados tan solo 28 cumplieron todos los criterios, por lo que fueron analizados en su totalidad para poder ser incluidos en la revisión. La calidad metodológica de los estudios se evaluó mediante la escala Newcastle-Otawa. De los 28 estudios seleccionados finalmente, 13 tenían una calidad metodológica buena, mientras que los 15 restantes tenían una calidad aceptable. Tras realizar la revisión, se puede concluir que el sedentarismo se ve aumentado paulatinamente con la edad mientras que la actividad física decrece, y consecuentemente, esta situación hace que el sobrepeso y la obesidad se vean incrementadas.  Abstract: The objective of this study was to find out what longitudinal researches have been carried out that have analyzed variables related to overweight, obesity and sedentary lifestyle in school age, and what data can be extracted from them. A systematic review of the MEDLINE (PubMed), Scopus, SportDiscus and WOS (Web of Science) databases was carried out following the PICOs model, using terms that define or represent children and young people of school age, who may or may not be overweight or obese. Following the PRISMA procedure, of the 2237 studies found only 28 met all the criteria and were therefore analyzed in their entirety for inclusion in the review. The methodological quality of the studies was assessed using the Newcastle-Otawa scale. Of the 28 studies finally selected, 13 were of good methodological quality, while the remaining 15 were of acceptable quality. After review was conducted, it can be concluded that sedentary lifestyle is gradually increased with age while physical activity decreases, and consequently, this situation causes overweight and obesity increase.

IntroductionIn previous studies, it has been found that on average, children consistently gained weight during the summer months at an increased rate compared with the 9-month school year. This contributed to an increased prevalence of overweight and obesity in children. Several obesity-related interventions have occurred during or targeting the summer months. We propose to conduct a systematic review and meta-analysis of the impact of obesity prevention and treatment interventions for school-age children conducted during the summer or targeting the summer months when children are not in school on their body mass index (BMI), or weight-related behaviours.Methods and analysesA literature search will be conducted by the first author (JPM) using MEDLINE/PubMed, Cochrane Library, Scopus, CINAHL, PsycINFO, EMBASE and Proquest Dissertations and Theses databases from the date of inception to present. Studies must examine interventions that address the modification or promotion of weight-related behaviours (eg, dietary patterns, eating behaviours, physical activity (PA), sedentary behaviour or sleep) and target school-age children (ages 5–18). The primary outcomes will be changes from baseline to postintervention and/or the last available follow-up measurement in weight, BMI, BMI percentile, standardised BMI or per cent body fat. Secondary outcomes will include changes in dietary intake, PA, sedentary behaviour or sleep. Risk of bias will be assessed using the Cochrane risk of bias tool for randomised and non-randomised studies, as appropriate.Ethics and disseminationBecause this is a protocol for a systematic review, ethics approval will not be required. The findings will be disseminated via presentations at scientific conferences and published in a peer-reviewed journal. All amendments to the protocol will be documented and dated and reported in the PROSPERO trial registry.PROSPERO registration numberCRD42016041750

Objective We conducted a meta-analysis and systematic review of literature comparing pre-reading and general reading in school-age children with nonsyndromic cleft palate with or without cleft lip (NSCP/L) to their peers without NSCP/L. Methods Our literature search identified 1238 possible records. After screening we identified 11 samples for inclusion for systematic review and eight for meta-analysis. We compared 292 children with NSCP/L to 311 peers for 23 pre-reading effect sizes and 17 general reading effect sizes (EFg). We conducted a random-effects metaregression using robust variance estimation. Results On average school-age children with NSCP/L scored lower on pre-reading (EFg = −0.36) and general reading measures (EFg = −0.38) compared to their peers. We conducted post-hoc analyses on phonological awareness and word decoding effect sizes; children with NSCP/L performed lower on phonological awareness (EFg = −0.22) and word decoding (EFg = −0.39) compared to their peers. There was weak evidence that hearing status and/or speech-language functioning might moderate reading development. There was limited evidence that age or socioeconomic status moderated reading development. However, samples did not consistently report several characteristics that were coded for this project. Conclusions Our findings suggest that school-age children with NSCP/L have persistent reading problems. Further research is needed to explore reading development in children with NSCP/L, as well as the relationships among hearing, speech, language, and reading development.

Global Prevalence

Background WHO-recommended prevalence thresholds for deciding schistosomiasis mass drug administration (MDA) are based on anecdotal evidence and unclear. Objectives This systematic review and meta-analysis commissioned by the WHO, as part of its new schistosomiasis evidence-based guideline development, was to generate a single and global prevalence threshold that should be applied in MDA programmes. Methods We searched several databases from 1979 to 31st March 2021 without language restriction. Two reviewers selected studies, extracted data and assessed the risk of bias using relevant risk of bias tools and resolved disagreements through discussion. The review followed the PRISMA guidelines. Data were analysed and presented as prevalence reduction (PR) and relative risk (RR) for dichotomous outcomes or mean difference for continuous outcomes with their 95% confidence intervals (CIs). Meta-regression of observations on prevalence rates and intensity of infection of MDA programmes and sensitivity analyses to assess the robustness of the results to the risk of bias components were performed. Evidence on benefits, harms, values, preferences, compliance, acceptability, equity and feasibility were also assessed. The overall level of evidence was graded using GRADE. Results Out of 1,232 studies retrieved, 38 studies met our inclusion criteria and 34 studies were included in the meta-analysis. No direct relation was observed between prevalence and intensity of infection. Praziquantel reduced prevalence of S. haematobium in school age children (SAC) at 12 months (RR 0.38, 95% CI 0.28 to 0.52; 8 studies, n=37,868); at 24 months (RR 0.30; 95% CI 0.30 to 0.52; 7 studies; n=37107); at 36 months (RR 0.39, 95% CI 0.21 to 0.71; 5 studies, n=28,146). There was no significant reduction in prevalence at 48 months (2 studies, n=10,954). For S. mansoni, there were reductions in prevalence at 12 months (RR 0.56, 95% CI 0.46 to 0.69; 14 studies, n=86,073); 24 months (RR 0.46; 95% CI 0.32 to 0.66; 14 studies; n=83,721);36 months (RR 0.44, 95% CI 0.33 to 0.58; 7 studies, n=70,933) and at 48 months (RR 0.25, 95% CI 0.11 to 0.59; 5 studies; n=27,483). Further analyses were performed from a series of created prevalence thresholds of 5%, 10%, 15%, 20%, 30% and ≥40% which showed differences in effect of MDA when each of the thresholds was applied. For annual MDA of school age children (SAC), school-based treatment (SBT) appears to perform better than community-wide treatment (CWT) in terms of prevalence reduction. For the different schistosome species, the model suggests, using the same prevalence threshold, it will take shorter time to reach elimination for S. haematobium than S. mansoni; annual MDA using SBT approach for S. haematobium will require about 10 years to achieve elimination whereas it will take over 10 years to around 15 years to achieve elimination for S. mansoni. Conclusion The evidence presented in this systematic review suggests that 10% prevalence should be used as the global prevalence threshold for implementing MDA in endemic countries.
