Background Underst and ing the correlates of dietary intake is necessary in order to effectively promote healthy dietary behavior among children and adolescents . A literature review was conducted on the correlates of the following categories of dietary intake in children and adolescents :  Fruit , Juice and Vegetable Consumption , Fat in Diet , Total Energy Intake , Sugar Snacking , Sweetened Beverage Consumption , Dietary Fiber , Other Healthy Dietary Consumption , and Other Less Healthy Dietary Consumption in children and adolescents . Methods Cross-sectional and prospect i ve studies were identified from PubMed , PsycINFO and PsycArticles by using a combination of search terms . Quantitative research examining determinants of dietary intake among children and adolescents aged 3–18 years were included . The selection and review process yielded information on country , study design , population , instrument used for measuring intake , and quality of research study . Results Seventy-seven articles were included . Many potential correlates have been studied among children and adolescents . However , for many hypothesized correlates substantial evidence is lacking due to a dearth of research . The correlates best supported by the literature are : perceived modeling , dietary intentions , norms , liking and preferences . Perceived modeling and dietary intentions have the most consistent and positive associations with eating behavior . Norms , liking , and preferences were also consistently and positively related to eating behavior in children and adolescents . Availability , knowledge , outcome expectations , self-efficacy and social support did not show consistent relationships across dietary outcomes . Conclusion This review examined the correlates of various dietary intake ; Fruit , Juice and Vegetable Consumption , Fat in Diet , Total Energy Intake , Sugar Snacking , Sweetened Beverage Consumption , Dietary Fiber , Other Healthy Dietary Consumption , and Other Less Healthy Dietary Consumption in cross-sectional and prospect i ve studies for children and adolescents . The correlates most consistently supported by evidence were perceived modeling , dietary intentions , norms , liking and preferences . More prospect i ve studies on the psychosocial determinants of eating behavior using broader theoretical perspectives should be examined in future research Background The use of financial incentives and penalties to encourage uptake of healthy behaviors is increasingly seen as a viable intervention in developed countries . Previous review s of the effectiveness of financial incentives and penalties for encouraging the uptake of healthy behaviors have focused on individual behaviors making it difficult to draw overall conclusions about the effectiveness of such interventions . This systematic review will explore the effectiveness of financial incentives and penalties for encouraging a wide range of behaviors , including : smoking cessation , increased physical activity , healthier dietary intake , sensible patterns of alcohol consumption , safe sun , safe sex , and primary preventive clinical behaviors . Methods Systematic methods will be used to search existing literature and screen studies for inclusion . All studies that meet the following inclusion criteria will be included in the review : participants were 18 years old or older and living in high-income countries ; interventions included cash or cash-like incentives to promote the uptake of healthy behaviors , or cash or cash-like penalties to discourage unhealthy behaviors ; the comparator was usual care or no intervention ; study design was r and omized controlled trial , cluster r and omized controlled trial , controlled before and after study , or interrupted time series analysis . Two review ers will independently screen the publications to ensure they meet the inclusion criteria . Quality will be assessed by two research ers , working independently , using the Cochrane risk of bias tool . Meta- analysis will be conducted , if appropriate . Any studies identified as at ‘ high risk of bias ’ will be excluded from meta- analysis . Discussion This systematic review will provide policy-relevant recommendations for the use of financial incentives and penalties as a method of encouraging uptake of healthy behaviors Environmental intervention represents an effective strategy to promote the purchase and consumption of healthful foods in community-based setting s. Three such studies promoted the consumption of healthier snacks and lower-fat foods at worksites and at schools . The first study examined lower prices and point-of-purchase promotion on sales of lower-fat snacks in vending machines in 12 worksites and 12 secondary schools . Price reductions of 10 % , 25 % and 50 % on lower-fat snacks result ed in an increase in sales of 9 % , 39 % and 93 % , respectively , as compared to usual-price conditions . The second study examined the impact of a 50 % price reduction on the consumption of fresh fruit and baby carrots in 2 secondary school cafeterias . In the third study , 20 secondary schools were r and omly assigned to either an environmental intervention or a control group for a 2-y period . The intervention increased the availability of lower-fat foods  and implemented student-based promotions . School-based environmental interventions to increase availability and promotion of lower-fat foods and healthier snacks can increase purchase of these foods among adolescents Background Growing evidence suggests that childhood and adolescence self-regulation contributes to multiple health , educational and social outcomes . Considering the potential impact of self-regulation skills on improved life chances in conjunction with evidence suggesting that self-regulation can be modified by interventions , there is a need to identify interventions which are most effective in improving childhood and adolescence self-regulation . The present systematic review was design ed to determine the effectiveness of universal interventions focused on enhancing the  self-regulation of children and adolescents . As secondary outcomes , we will also examine the effectiveness of such interventions on distal health and social outcomes . Methods Eligible studies include r and omised controlled trials ( including cluster r and omised trials ) reporting on universal interventions design ed to improve self-regulation in childhood and adolescence ( age 0–19 years ) . The following data bases will be search ed for peer- review ed publications using an iterative search strategy : Medline , PsycINFO , EMBASE , ERIC , CINAHL Plus , British Education Index , Child Development & Adolescent Studies and CENTRAL without applying language or date filters . Additionally , reference lists and citations of included studies will be search ed for eligible studies . A 10 % proportion of the total titles and abstract s will be r and omly selected and screened independently by two review ers ( AP and DH ) . Results will be compared to ensure less than 5 % discrepancy , followed by screening of all results by one review er ( AP ) . Full-text review and data collection will be independently performed by two review ers . Any discrepancies will be solved by mutual discussion , and if unresolved , a third review er ( RV ) will be consulted . Meta- analysis will be conducted to quantify trial effects , if the data is sufficiently homogenous to allow quantitative synthesis . Otherwise , results will be described narratively . Discussion The evidence derived from the systematic review will strengthen the evidence base to inform planning of effective interventions targeting self-regulation skills in childhood and adolescence . This will benefit policy makers , academicians , research ers , health professionals , and also , young people who will benefit from policy and interventions informed by this review . Systematic review registration CRD42016047661 BACKGROUND The number of placebo-controlled r and omized studies relating to EEG-neurofeedback and its effect on neurocognition in attention-deficient/hyperactivity disorder ( ADHD ) is limited . For this reason , a double blind , r and omized , placebo-controlled study was design ed to assess the effects of  EEG-neurofeedback  on neurocognitive functioning in children with ADHD , and a systematic review on this topic was performed . METHODS Forty-one children ( 8 - 15 years ) with a DSM-IV-TR diagnosis of ADHD were r and omly allocated to EEG-neurofeedback or placebo-neurofeedback treatment for 30 sessions , twice a week . Children were stratified by age , electrophysiological state of arousal , and medication use . Neurocognitive tests of attention , executive functioning , working memory , and time processing were administered before and after treatment . Research ers , teachers , children and their parents , with the exception of the neurofeedback-therapist , were all blind to treatment assignment . Outcome measures were the changes in neurocognitive performance before and after treatment . CLINICAL TRIAL REGISTRATION www . clinical trials.gov : NCT00723684 . RESULTS No significant treatment effect on any of the neurocognitive variables was found . A systematic review of the current literature also did not find any systematic beneficial effect of EEG-neurofeedback on neurocognitive functioning . CONCLUSION Overall , the existing literature and this study fail to support any benefit of neurofeedback on neurocognitive functioning in ADHD , possibly due to small sample sizes and other study limitations Objective : To systematic ally summarize the experimental effects of exercise on cognitive-related memory function among young to middle-aged adults , which has yet to be done in the literature . Data Source : PubMed . Study Inclusion and Exclusion Criteria : Studies were included if they were published in the English language , indexed in PubMed , employed an experimental study design ( eg , traditional parallel group r and omized controlled trial : either acute intervention or chronic/training intervention study ) , and conducted among human adults . Studies were excluded if nonhumans ( ie , animal models ) were studied , if children/adolescents ( < 18 years ) or older adults ( > 50 years ) were evaluated , and if select chronic diseases ( eg , diabetes and dementia ) were present . Data Extraction : A systematic review approach was employed . Data Synthesis : An extraction table was created synthesizing the key results , and recommendations for future research are emphasized . Results : Among the 17 evaluated studies , 2 were published before the year 2000 ( ie , 1998 and 1999 ) , 2 were published in 2007 , and the remaining 13 were published in the years 2011 and beyond . This highlights the emergence of this research topic within this age-group ( young to middle-aged adults ) . Among the 17 evaluated studies , 14 were conducted among healthy sample s , with 3 conducted among those with a diagnosis of depression . Among the 17 studies , 4 employed a chronic training protocol , with 13 utilizing an acute exercise protocol . Among the 3 experimental studies in the depressed population , all demonstrated a favorable effect of exercise on memory function . Among the 14 trials in the nondepressed population , 10 ( 71 % ) demonstrated a favorable effect of exercise on some aspect of memory function . Conclusion : Acute and chronic exercise appears to play a pronounced effect on memory function  among young to middle-aged adults . Implication s and recommendations for future research are outlined in this systematic review BACKGROUND Peer mediated intervention ( PMI ) is a promising practice used to increase social skills in children with autism spectrum disorder ( ASD ) .  PMIs engage typically developing peers as social models to improve social initiations , responses , and interactions . METHOD The current study is a systematic review examining PMIs for children and adolescents with ASD conducted using group design s. Five studies met the pre-specified review inclusion criteria : four r and omized controlled trials and one pre- and post-test design . RESULTS Four of the studies were conducted in school setting s , whereas one study was conducted in a camp setting . The studies all reported that participants improved in social skills ( e.g. , social initiations , social responses , social communication ) post intervention . Additionally , sustainment , generalization , and fidelity of implementation were examined . CONCLUSION PMI is a promising approach to address social skills in children with ASD , and this approach can be conducted in meaningful real-word context s , such as schools . Limitations of the studies as well as future directions are discussed Objective : Refined grains consumption is positively associated with obesity .  White rice is the most usual refined grain in Iran . However , few studies have assessed the association between rice intake and anthropometric measures among adolescents . Therefore , we aim ed to compare anthropometric measures as well as the diet quality indices across the tertiles of  white rice consumption among Iranian adolescents . Methods : This cross-sectional study was conducted on 415 female adolescents who were chosen by using a systematic cluster r and om sampling .  Dietary intake assessment was done using a vali date d semiquantitative food frequency question naire . Anthropometric measures were done according to the st and ard protocol s. Diet quality indices ( including dietary energy density [ DED ] , nutrient adequacy ratio [ NAR ] , and mean adequacy ratio [ MAR ] ) were calculated using st and ard definitions . Results : The prevalence of overweight across the tertiles of rice consumption was 11.6 , 17.8 , and 24.6 % , respectively ( p = 0.03 ) . Corresponding values for obesity were 2.1 , 5.7 , and 8.6 % , respectively ( p = 0.04 ) . A significant positive association was observed for the prevalence of central obesity across the tertile of rice intake ( 13.1 , 21.4 , and 28.1 % ; p = 0.02 ) . Dietary fiber and energy intake and diet quality indices were significantly different among different tertiles of white rice intake . Those in the highest tertiles of white rice intake had the lowest scores for MAR and NAR and highest scores for DED . Conclusion : There was significant association between rice consumption and obesity as well as diet quality indices among Iranian adolescents One of the main focuses of lifestyle modification for the prevention of osteoporosis and osteoporotic fractures  in Japan is improvement in dietary calcium intake . However , virtually no r and omized controlled trial to assess the preventive effects of administration of calcium on the risk of fractures has been conducted in Japan . In this study , we review ed all the scientific papers currently available from medical literature data bases to propose evidence -based recommendations on the preventive procedures for osteoporosis . The result of the present systematic review gives the evidence showing that calcium supplementation or optimal dietary calcium intake increases bone density in childhood and adolescence and reduces the risk of fracture due to osteoporosis in the elderly people regardless of the gender . The evidence also supports the current health policy guiding the elderly to increase their dietary calcium intake in daily life Background Various clinical trials suggested that risperidone was beneficial in the treatment of autism spectrum disorder ( ASD ) in children and adolescents . Objective The aim of this systematic review was to determine the efficacy , acceptability and tolerability of risperidone in the treatment of children and adolescents with ASD . Data sources The data bases of Scopus , PubMed , CINAHL and Cochrane Controlled Trials Register were search ed in February 2017 . Study eligibility criteria , participants and interventions Eligible RCTs of risperidone in the treatment of child and adolescent patients with ASD . Language s were not restricted . Study appraisal and synthesis methods The full-text versions of relevant studies were thoroughly assessed and extracted . The primary efficacy of outcome was the pooled response rate and the pooled mean changed scores of the st and ardized rating scales for ASD . Results A total of 372 r and omized subjects from seven RCTs were included in this review . In acute treatment , the pooled mean change score of the Aberrant Behavior Checklist for irritability subscale ( ABC-I ) and response rate for the risperidone-treated group had a greater significance than that of the placebo-treated group . In the long-term treatment , the pooled mean change score of the CARS in the risperidone-treated group was significantly greater than that in the placebo-treated group . According to the discontinuation phase , the overall pooled relapse rate of the risperidone-treated group was significantly less than that of the placebo-treated group . The rates of pooled overall discontinuation and discontinuation due to adverse events rates were not different between the two groups in acute and long-term treatments . Limitations A small study was included in the current review . Conclusion In relation to the current systematic review , risperidone is efficacious in the treatment of symptoms in children and adolescents with ASD . Although its acceptability is comparable to placebo , treatment with risperidone is well tolerated in children and adolescents with ASD
Taken together , evidence suggests a positive association between healthy dietary consumption and executive functioning .
A systematic review was conducted to evaluate whether healthier dietary consumption  among children and adolescents impacts executive functioning .
