AIM： To assess the effcacy and safety of probiotics for preventing pediatric：（1） antibiotic associated diarrhea and （2） clostridium diffcile （C. diffcile） ***： On June 3, 2013, we searched PubMed （1960-2013）, EMBASE （1974-2013）, Cochrane Da-tabase of Systematic Reviews （1990-2013）, CINAHL （1981-2013）, AMED （1985-2013）, and ISI Web of Science （2000-2013）. Additionally, we conducted an extensive grey literature search including contact with National Institutes of Health Clinical Trials Registry, abstracts from annual infectious disease and gastroen-terology meetings, experts in the feld and correspondence with authors. The primary outcomes were the incidence of antibiotic-associated diarrhea （AAD） and C. difficile infections （CDI）. Dichotomous outcomes （e.g. , incidence of AAD or CDI） were pooled using a random-effects model to calculate the relative risk and corresponding 95% confidence interval （95%CI） and weighted on study quality. To explore possible explanations for heterogeneity, a priori subgroup analysis were conducted on probiotic strain type, daily dose, quality of study and safety of probiotics. The overall quality of the evidence supporting each outcome was assessed using the grading of recommendations, assessment, development and evaluation ***： A total of 1329 studies were identifed with 22 trials （23 treatment arms and 4155 participants） meeting eligibility requirements for our review of prevention of AAD and 5 trials （1211 participants） for the prevention of CDI. Trials in adult populations, trials of uncertain antibiotic exposure or studies which did not provide incidence of AAD were excluded. We found 12 trials testing a single strain of probiotic and 10 trials testing a mixture of probiotic strains. Probiotics （all strains combined） signifcantly reduced the incidence of pediatric AAD （pooled RR = 0.42, 95%CI： 0.33-0.53） and significantly reduced pediatric CDI （pooled RR = 0.35, 95%CI： 0.13-0.92）. Of the two strains wi
