Epidemiological Characteristics

Abstract Background: We conducted a meta-analysis and systematic review to identify a reliable estimate of sleep disorders prevalence among children in mainland China and to describe its epidemiological characteristics.Methods: Relevant studies were searched thoroughly via electronic databases included China National Knowledge Infrastructure, Wanfang,Weipu,PubMed,Web of Science and Medline databases from inception until December 2020.Prevalence estimates were calculated by random-effects models. The sources of heterogeneity were explored using subgroup analyses and Meta-regression analysis, and publication bias was estimated by funnel plots and Egger’s Test. Results: Overall, 66 studies were included in this meta-analysis, which revealed that the pooled prevalence of sleep disorders was 37.6% (95%CI: 34.3-40.9%)with high heterogeneity (I2=99.6%,P=0.000).The prevalence rate of sleep disorders among males was higher than females (OR:1.01,95%CI:1.05-1.13).In all age groups, the prevalence rates of sleep disorders increased with age, including infancy or early childhood group(33.3%),pre-school group(38.9%), school-age group(43.7%). The prevalence rate in South China (30.4%, 95%CI: 23.9–36.8%) was the lowest, and the highest prevalence rate was in West China (47.4 %,95%CI:35.9–58.9%), which than any other region in China. The point estimate for sleep disorders prevalence obtained using the CSHQ criterion was higher than other criteria.Meta-regression indicated that age group could influence prevalence estimation (P = 0.011).Conclusions: Over the past two decades, the prevalence rate of sleep disorders among children in mainland China has increased, significantly affecting two-fifth of the school-age children. The prevalence rate of sleep disorders in west China was significantly higher than in any other area. There is still a lack of guidelines on children's sleep disorders in mainland China, so future research should pay special attention to the sleep disorders of school-age children and children in economically backward areas.

Background: In recent years, zinc deficiency in children has attracted global attention. There are some differences in zinc deficiency in different countries and regions. However, there are few multi-center and large-sample studies on zinc deficiency in children in mainland China. Objective: To evaluate the status of zinc deficiency and its influence factors in children under 14-year-old in mainland China, and to provide evidence-based evidence for the strategy of prevention and treatment of zinc deficiency in children. Methods: PubMed, Embase, CNKI and other databases were searched about the cross-sectional survey literature on zinc deficiency and its influencing factors of under 14-year-old children in mainland China from 2005 to 2021. Stata 14.0 statistical software was used for Meta-analysis. Two independent reviewers identified eligible studies. Results: We identified 55 studies with 292,877 healthy children and adolescents in the Meta-analysis. The overall zinc deficiency rate was 27.0% (95% CI 22.8%-31.3%). From coastal areas of China showed that the zinc deficiency rate was 21.7% (95% CI 16.2%-27.1%) as 29.6% (95% CI 24.9%- 34.4%) from inland area of China. The zinc deficiency rate in the male group was greater than in the female group, and the difference was statistically significant [OR=1.052, 95% CI (1.019, 1.087), p=0.002]. The zinc deficiency rate in infant group was higher than that in toddler group [OR=1.38, 95% CI (1.16, 1.64), p=0.000], preschool group [OR=1.475, 95% CI (1.163, 1.870), p=0.001], and school-age group [OR=1.746, 95% CI (1.257, 2.425), p=0.001], with statistical significance. There was no significant difference in zinc deficiency rate between the toddler group and the preschool group [OR=1.059, 95% CI (0.918, 1.222), p=0.429], the toddler group and the school-age group [OR=1.136, 95% CI (0.848, 1.523), p=0.394], and the preschool group and the school-age group [OR=0.986, 95% CI (0.754, 1.291), p=0.919]. There was no statistically significant difference in zinc deficiency rate between the groups of well-educated and the poor-educated dietary provider. (OR=1.095, 95% CI (0.867, 1.383), p=0.446), and no statistical significance in zinc deficiency rate between urban group and rural group [OR=1.152, 95% CI (0.810, 1.637), p=0.432]. Conclusions: At present, zinc deficiency in children and adolescents in mainland China is still serious, especially in infants. The zinc deficiency rate in male children was more serious than that of female children. The zinc deficiency rate of children in inland areas was higher than that in coastal areas. Factors such as different educational level of food providers and different areas from urban or rural were not the major influencing factors of zinc deficiency.

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.

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
