Objectives:The objective of research is to use meta-analysis for bibliotherapy on anxiety and depression disorders for children and adolescent in recent ten years in Iran and abroad.The aim was to combine the results of different researches and extract new and comprehensive results and calculate the effect sizes.Also the research studied that how much the type of dependent variables and different moderators could be effectiveMaterials and Methods:In this study, meta-analysis was considered as a statistical technique for determining,collecting,combining and summarizing the finding that relates to the effect of bibliotherapy in children and adolescent.The population of the present meta-analysis was preceding studies in the field of bibiotherapy and was the all scientific papers published in academic journals,scientific conferences and thesis in the 10-year period (1394-1384) by the subject of bibliotherapy.The papers must be available in different database and have the necessary condition.According to Inclusion criteria of study,14 work by 20 effect size get.To calculate the effect size,CMA software version 2 was usedResults:Findings showed that overall effect size was 0.423 that is average according to the table of Cohen.The finding of this meta-analysis is compliance with previous studies that shows bibliotherapy is an effective and efficient approach for treating and helping to treat disorders and preventing and development of children and adolescent. Findings also showed that moderators like type of therapist, contact to therapist are not very effectiveConclusion:The effectiveness of bibliotherapy for children and adolescent is average and could be used as a treatment method for depression and anxiety disorders

Background & Objectives: This study was performed to meta-analysis of available studies on the effectiveness of treatments and offer effective treatment for prisoners suffering from mental disorders. Materials & Methods: The research method was meta-analysis. The study population included all studies with experimental and quasi-experimental designs from 1991 to 2017 in 1124 cases was about the prisoners. 50 studies that had criteria for entering the meta-analysis were selected using a census method. Data collection was done through a researcher-made checklist. The calculation of effect size was done through index r by CMA2 software. Results: the effect size index of all studies according random effects model was t r=0.603 and cognitive therapy with the effect size of r=0.669 was evaluated as the most effective treatment method. Conclusion: In general, the use of therapeutic methods for the treatment of mental disorders in prisoners is effective and the effect of the Cohen classification is high.

Background and objective:Non-alcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver disease which is created by the accumulation of fat in the liver. Several studies have reported the prevalence of fatty liver in Iran, with different results. Our goal is to estimate the Overall prevalence of fatty liver in Iranian children and adolescents.Materials and methods:We searched the national and international databases (PubMed ,Science Direct ,Scopus ,Web of Science),) Magiran,Iran Medex , and Scientific Information Database) With keyword " prevalence ", "Nonalcoholic fatty liver", "fatty liver", "children", "adolescents" and "Iran" from the years 1998-2017. The variance of each study was calculated by the binomial distribution formula. We used a random effect model to combine the prevalence rates reported in the studies. The STATA software (version 12) was used to analyze the data.Results: Eight studies were identified with of a total of 6118 subjects. The pooled prevalence of NAFLD in both population (male and female) was 27.88% (95%CI: 18.7% to 37.02%) .In both populations there was marked heterogeneity between studies (I2 = 99.3%). There was evidence that prevalence was generally higher in males compared with females .Conclusion:Our review suggests the prevalence of NAFLD in children and adolescent is high, particularly in those who are obese and in males.

Background: Sexual dysfunction in women is common and is one of the factors of divorce and disintegration in families. The aim of this study was to determine the prevalence of female sexual dysfunction in Iran using a descriptive meta-analysis study. Materials and Methods: In this meta-analysis study, the databases of ISI Web of Knowledge, PubMed, Scopus, Google Scholar and interior databases were searched during 2001 to 2015. Between the studies with regard to the inclusion and exclusion criteria, 11 studies were selected. Heterogeneity assessed by Cochran’s Q statistic and I2 index. Cause of heterogeneity was evaluated using meta-regression model. Results: Total samples size in the 11 studies were 8248. Cochran’s Q statistic and I2 index revealed observable heterogeneity between studies (Q=552.70, P-value 2= 98.4). Overall prevalence of female sexual dysfunction based on the random effect model (Inverse Variance Method) was obtained 43.9% (95% CI: 35.0 – 52.8). Prevalence of desire, arousal, lubricating, orgasmic, satisfaction and pain disorders were 42.7 % (32.0-53.4), 38.5% (27.6-49.5), 30.6% (22.0-39.2), 29.2% (24.1-34.3), 21.6% (11.5-31.8) and 40.1% (31.8-48.3), respectively. Conclusion: This meta-analysis showed a comprehensive view about female sexual function in Iran. However, compared with other developing countries, Iran has a favorable situation. Considering the high prevalence of female sexual dysfunction, more epidemiological research for detection of affecting factors, intervention and preventive actions seem essential.

Background: The use of industrial drug such as methamphetamine ,reported asan important health problemin students and adolescents in around the world. It was regarded as a concerning event in the students by World Health Organization (WHO). Therefore, the aim of present study was determining prevalence of methamphetamine in the Iranian male student using a meta-analysis study. Material and Methods: the present meta-analysis was conducted using random effect model. For the selecting studies on the prevalence of methamphetamine were searched in SID, Iranmedex, Magiran, Medlib, Pubmed, ISIand Scopus databases by three researchers from 2001 to2014. Then, were identified 69articles and after reviewing based on inclusion and exclusion criteria wereincluded10 articles in the study and was used from the random-effects model by CMA-2 software for analyzing data. Also, the heterogeneity was determined to Q,Ƭ2 and I2 coefficients. Results:The pooled effect size (prevalence)was obtained around 1.2% (CI 95%: 0.8-1.6). Also, in the subgroup analysis, the prevalence of amphetamine was attained 1.6% and 0.9%after and before 2010, respectively. Moreover, the indices related to heterogeneity were including; Q=6.38, I2=0.31 and T2=0.16. In addition, there was a significant association between age and the prevalence of methamphetamine (B=1.13, p=0.01) in the meta-regression analysis. Discussion: Although, the prevalence of methamphetamine was less than other drugs in the male students. But, the increasing prevalence of methamphetamine in the Iranian students, especially in male students, is as a serious warning to the authorities and families.
