INTRODUCTION: A @entity716 may be sufficiently traumatic to induce symptoms of @entity1005 ( @entity1005 ), which could impact outcomes in @entity716 ( @entity716 ). The objectives of this systematic review and meta-analysis were to estimate the prevalence of @entity1005 symptoms in relation to @entity716 in @entity716 and to identify risk factors for the development of @entity1005 symptoms. METHODS: We searched electronic databases and conducted manual searching of reference lists and tables of contents to identify relevant studies. Quantitative studies were included if the population was experiencing @entity716 and if @entity1005 was measured in relation to @entity716 . Prevalence of @entity1005 symptoms and diagnoses were meta-analyzed using a random effects model. Potential risk factors for @entity1005 symptoms were summarized qualitatively. RESULTS: Thirteen studies were included. Eight studies assessed @entity1005 symptoms, three studies assessed full @entity1005 , and two studies assessed both. The pooled prevalence of @entity1005 symptoms was 42% (95% CI 30%-55%), and the pooled prevalence of a @entity1005 diagnosis was 30% (95% CI 21%-40%). Exploratory subgroup analyses suggest that prevalence may be higher in affective @entity716 and inpatient samples. Evidence from included studies implicate @entity308 and @entity148 as potential risk factors for @entity1005 symptoms. CONCLUSIONS: Approximately one in two @entity1 experience @entity1005 symptoms and one in three experience full @entity1005 following a first @entity716 . Evidence-based interventions to treat @entity1005 symptoms in the context of @entity716 are needed to address this burden and improve outcomes after the first @entity716 . Further studies are needed to clarify the associated risk factors.
