Diet and special educational needs (SENs) among children and adolescents: a systematic review

Abstract

<jats:title>Abstract</jats:title> <jats:p>Special educational needs (SENs) refer to children and adolescents needing additional educational support. Diet during pregnancy and pediatric age can influence the prevalence/severity of symptoms in SEN-related conditions/disabilities. This review aims to summarize associations between (i) pregnant women's diet and the prevalence of SEN-related conditions/disabilities among children/adolescents and (ii) the diet of children/adolescents with SEN-related conditions/disabilities and their symptomatology/well-being. A literature search was performed on Medline and Scopus, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The following inclusion criteria were considered, for each aim: (i) children/adolescents aged 19 years and younger, pregnant women's diet/nutrition, and diagnosis of SEN-related conditions/disabilities in children/adolescents; (ii) children/adolescents aged 19 years and younger, children/adolescents' diet/nutrition, and symptomatology/well-being of children/adolescents with SEN-related conditions/disabilities. 87 articles were included, referring to 10 different SEN-related conditions/disabilities, from which attention-deficit/hyperactivity disorder (ADHD) (41 articles) and autism spectrum disorder (ASD) (34 articles) stand out. Noteworthy results were seen regarding maternal caffeine consumption; pregnant woman multivitamin supplementation, high-sugar foods, and beverage intake during childhood/adolescence; maternal breastfeeding; and vitamin D supplementation. Despite the notable associations, further research using more standardized and homogeneous methodologies is needed to strengthen these findings. PROSPERO registration number: CRD42022313235.</jats:p>
