Weight status in individuals with autism spectrum disorder: A study protocol for systematic review and meta-analysis.

ABSTRACT: BACKGROUND:Weight status and autism spectrum disorder (ASD) are rising public health concerns. An increasing number of reports indicate that individuals with ASD may have unhealthy weight status, but the evidence is mixed. To understand the weight status in individuals with ASD and provide strategies for prevention and intervention, we describe the protocol for a systematic review and meta-analysis aimed at assessing the prevalence of obesity, overweight, and underweight in ASD. METHODS:A broad range of key bibliographic databases including MEDLINE (PubMed), Embase, Cochrane, and ISI Web of Science will be searched to identify studies reporting the prevalence of obesity, overweight, and underweight in patients with ASD. Retrieved records will be independently screened by 2 authors and relevant estimates will be extracted from studies reporting data on obesity, overweight, and underweight prevalence among individuals with ASD. The assessment of study quality will be conducted primarily using the Newcastle-Ottawa scale and checklist proposed by the Joanna Briggs Institute. Prevalence estimates of obesity and overweight will be separately pooled using random-effects model. The pooled estimates will be summarized and presented by regional groupings. Subgroup analysis will be conducted for variables (such as study setting, participants' age, and geographical region) across studies, depending on data availability. Between-study heterogeneity will be assessed using the I statistic and explored through subgroup analyses. This systematic review and meta-analysis will be reported following the preferred reporting items for systematic reviews and meta-analyses checklist and the meta-analysis of observational studies in epidemiology statements guidelines for meta-analysis and systematic reviews of observational studies. RESULTS:In this study, we will outline details of the aims and methods on the meta-analysis of weight status of individuals with ASD. CONCLUSION:The results of this study will summarize the current data of weight status of individuals with ASD.

Project description:An ever-growing literature has aimed to determine how individuals with autism spectrum disorder (ASD) differ from their typically developing (TD) peers on measures of multisensory integration (MSI) and to ascertain the degree to which differences in MSI are associated with the broad range of symptoms associated with ASD. Findings, however, have been highly variable across the studies carried out to date. The present work systematically reviews and quantitatively synthesizes the large literature on audiovisual MSI in individuals with ASD to evaluate the cumulative evidence for (a) group differences between individuals with ASD and TD peers, (b) correlations between MSI and autism symptoms in individuals with ASD and (c) study level factors that may moderate findings (i.e., explain differential effects) observed across studies. To identify eligible studies, a comprehensive search strategy was employed using the ProQuest search engine, PubMed database, forwards and backwards citation searches, direct author contact, and hand-searching of select conference proceedings. A significant between-group difference in MSI was evident in the literature, with individuals with ASD demonstrating worse audiovisual integration on average across studies compared to TD controls. This effect was moderated by mean participant age, such that between-group differences were more pronounced in younger samples. The mean correlation between MSI and autism and related symptomatology was also significant, indicating that increased audiovisual integration in individuals with ASD is associated with better language/communication abilities and/or reduced autism symptom severity in the extant literature. This effect was moderated by whether the stimuli were linguistic versus non-linguistic in nature, such that correlation magnitudes tended to be significantly greater when linguistic stimuli were utilized in the measure of MSI. Limitations and future directions for primary and meta-analytic research are discussed.

Project description:BackgroundAutism spectrum disorder (ASD) is a neurodevelopmental disorder defined by persistent deficits in social functioning and the presence of restricted and repetitive behaviours (RRBs). RRBs refer to four subtypes of behaviour including repetitive movements, speech, or use of objects; insistence on sameness; restricted interests; and sensory processing abnormalities. Many individuals with ASD also experience anxiety, which compounds ASD-related difficulties and inhibits daily functioning. RRBs have been found to be positively associated with anxiety; however, our understanding of the interplay between RRB subtypes and anxiety remains unclear. Thus, the current review aims to clarify the association between RRBs and anxiety by conducting a systematic review and meta-analysis.MethodsTo identify relevant studies, we will search five databases: CINAHL Plus, Cochrane Central Register of Controlled Trials, Ovid MEDLINE, PsycINFO, and Scopus. Articles included in the review will have their titles, abstracts, and full texts reviewed by two independent authors and their methodological quality assessed via the modified Newcastle-Ottawa Scale. Random-effects meta-analyses will then be conducted to calculate the pooled association between RRB subtypes and anxiety. Sensitivity analyses will also be conducted to assess the potential impact of bias, missing data, outliers, and methodological differences on this relationship. Additionally, this review will collate the factors which may influence the anxiety-RRB relationship to help identify who is most vulnerable to developing anxiety.DiscussionThis will be the first review to examine the association between the four subtypes of RRBs and anxiety in individuals with ASD. Understanding this relationship, and the factors associated with this, may help clinicians understand the different underpinnings and presentations of anxiety within this population with potential implications for assessment and treatment.Systematic review registrationPROSPERO CRD42020185434.

Project description:BackgroundThe aim of this study was to assess the efficiency and safety of acupuncture in core symptomatic improvement of children with autism spectrum disorder (ASD).MethodsWe searched the following databases: Cochrane Library, PubMed, Embase, Medline, China National Knowledge Infrastructure (CNKI), Wanfang, Chinese Science and Technology Periodical (VIP) and Chinese Biological Medicine (CBM), from 1 January 2012 to 25 September 2022. The Autism Behavior Checklist (ABC), Childhood Autism Rating Scale (CARS), and Autism Treatment Evaluation Checklist (ATEC) were adopted as outcome indicators. Three reviewers independently assessed the risk of bias (ROB) and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE)assessment. Utilizing Review Manager (RevMan) 5.3 and Stata 12.0, data were analyzed.ResultsA total of 38 trials were included, and 2862 participants participated in qualitative synthesis and meta-analysis. Only 1 trial was assessed as having a low ROB, and 37 trials were assessed as having an overall high ROB. The quality of evidence for most indicators were considered very low by the GRADE criteria. The results showed that acupuncture groups might have a higher clinical effective rate than nonacupuncture groups (relative risk [RR] = 1.33,95% confidence interval [CI] = 1.25-1.41; heterogeneity: x2=18.15, P = .64, I2 = 0%). Regarding changes in ABC scores, the acupuncture groups might exhibit greater decrease than nonacupuncture groups (MMD = -6.06, 95%CI = -7.25 to -4.87, P < .00001; heterogeneity: x2 =73.37, P = .03, I2 = 77%). In terms of changes in CARS score, acupuncture group may benefit more than nonacupuncture group (MMD = -3.93, 95%CI = 4.90 to -2.95, P < .00001; heterogeneity: x2=234.47, P < .00001, I2 = 90%). Additionally, in terms of ATEC score, acupuncture groups showed more benefit than nonacupuncture groups (MMD = -10.24, 95%CI = -13.09 to -7.38, P < .00001; heterogeneity: x2=45.74, P = .04, I2 = 85%). Both subgroup analysis and sensitivity analysis are existing heterogeneity. Only 1 RCT study involved adverse events with mild symptoms that did not interfere with treatment and evaluation.ConclusionChildren with ASD may benefit from acupuncture because of its effectiveness and safety. Nevertheless, given the low quality of the evidence for the assessed outcomes and the high ROB of analyzed trials, the results should be regarded with caution.
