The studies included in this review show evidence of improvements in protective behaviours and knowledge among children exposed to school-based programmes, regardless of the type of programme. The results might have differed had the true ICCs or cluster-adjusted results been available. There is evidence that children's knowledge does not deteriorate over time, although this requires further research with longer-term follow-up. Programme participation does not generate increased or decreased child anxiety or fear, however there is a need for ongoing monitoring of both positive and negative short- and long-term effects. The results show that programme participation may increase the odds of disclosure, however there is a need for more programme evaluations to routinely collect such data. Further investigation of the moderators of programme effects is required along with longitudinal or data linkage studies that can assess actual prevention of child sexual abuse.

AIM It has been reported that rates of epilepsy and mortality are higher among the population with autism spectrum disorder (ASD) than in the general population. The aim of this systematic review is to provide comprehensive evidence for clinicians, carers, and people with ASD regarding these outcomes.METHOD Studies were eligible for inclusion if the main focus of the study involved observation over a period of 12 months or more of an initially defined population (with appropriate diagnostic label). Studies were also required to have at least 30 participants in order to differentiate case series from cohort studies. The Cochrane Database of Systematic Reviews, the Database of Reviews of Effectiveness, MEDLINE, PsycINFO, EMBASE, and CINAHL were searched. The date of the last search was September 2010. The risk of bias of included studies was assessed and a meta-analysis was undertaken.RESULTS Twenty-one studies were identified, 16 measuring the percentage of participants with epilepsy and five measuring mortality using a standardized mortality ratio. The pooled estimate for the percentage of participants with epilepsy was 1.8% (95% CI 0.4-9.4%) in studies in which the majority did not have an intellectual disability and the mean age was <12 years at follow-up, and 23.7% (95% CI 17.5-30.5%) in studies in which the majority did have an intellectual disability and the mean age at follow-up was more than 12 years. The pooled estimate for the standardized mortality ratio was 2.8 (95% CI 1.8-4.2). INTERPRETATIONThe prevalence of epilepsy is higher among the population with ASD than in the general population. People with ASD have a higher risk of mortality than the general population. This has important health promotion implications.

Objective: To assess evidence of the effectiveness of school-based education programs for the prevention of child sexual abuse (CSA). The programs deliver information about CSA and strategies to help children avoid it and encourage help seeking. Methods: Systematic review including meta-analysis of randomized controlled trials (RCTs), cluster RCTs, and quasi-RCTs. Results: Twenty-four studies with 5,802 participants were included. Child self-protective skills, odds ratio ¼ 5.71, confidence interval ¼ [1.98, 16.51]; factual, standardized mean difference (SMD) ¼ 0.61 [0.45, 0.78]; and applied knowledge, SMD ¼ 0.45 [0.24, 0.65], increased in the intervention group, and knowledge gains were retained at 6 months, SMD ¼ 0.69 [0.51, 0.87].There were no differences in anxiety or fear, SMD ¼ À0.08 [0.22, 0.07], and findings regarding disclosure of abuse were inconclusive. Conclusion: Children's self-protective skills and knowledge can be increased by participation in school-based sexual abuse prevention programs. However, it is unknown whether gains in skills and knowledge actually decrease the likelihood of CSA.
