Association between childhood allergic diseases, educational attainment and occupational status in later life: systematic review protocol.

INTRODUCTION: Childhood allergic diseases may prevent affected children from achieving their academic potential. Potential mechanisms include absence from school due to illness and medical appointments. Experience of symptoms in classes or leisure time, and stigma associated with visible signs and symptoms, including skin disease, requirements for medication during school time or the need for specific diets, may also contribute to reduced educational attainment. Studies have investigated the association between specific allergic diseases and educational attainment. The aim of this study is to systematically review the literature on allergic diseases, educational attainment and occupational status, and if possible, calculate meta-analytic summary estimates for the associations. METHODS: Systematic electronic searches in Medline, EMBASE, Cochrane, Cumulative Index to Nursing & Allied Health Literature (CINAHL), PsycINFO and education Resources Information Center (ERIC); hand search in reference lists of included papers and conference reports; search for unpublished studies in clinical trial registers and the New York Academy of Medicine Grey Literature Report; data extraction; and study quality assessment (Newcastle-Ottawa Scale) will be performed. ANALYSIS: Data will be summarised descriptively, and meta-analysis including meta-regression to explore sources of heterogeneities will be performed if possible. ETHICS AND DISSEMINATION: Dissemination in a peer-reviewed, open-access, international scientific journal is planned. PROSPERO REGISTRATION NUMBER: CRD42017058036.
