Dietary intake and risk of asthma in children and adults: protocol for a systematic review and meta-analysis

Abstract

Background Diet has been proposed to modulate the risk of asthma in children and adults. An increasing body of epidemiological studies have been published in the last year investigating the association between dietary intake and asthma. As part of the Evidence-Based Clinical Practice Guideline Task Force on ‘Lifestyle Interventions in Allergy and Asthma’ funded by the European Academy of Allergy and Clinical Immunology, we will use a systematic approach to review the evidence from published scientific literature on dietary intake and asthma in children and adults.

Methods This systematic review will be carried out following the PRISMA guidelines. The protocol has been published in PROSPERO (CRD42016036078). We will review the evidence from epidemiological studies in children (from the age of 2 years) and adults and dietary intake of foods and nutrients.

Discussion The findings from this review will be used as a reference to inform guideline recommendations.
