Consumo de cafeína durante a gestação e transtorno de déficit de atenção e hiperatividade (TDAH): Uma revisão sistemática da literature

Abstract

This aim of this study was to conduct a systematic literature review on the association between maternal caffeine intake during pregnancy and attention deficit hyperactivity disorder (ADHD) in childhood. The systematic multiple-stage literature search in PubMed, LILACS, BIREME, and PsycINFO was limited to research in human subjects and published in Portuguese, English, and Spanish. A total of 373 references were retrieved. Of these, only five met the study’s objectives and were kept in the review. Most of the studies employed a longitudinal design, were conducted in developed countries, and were published in the last five years. Only one study found a positive association. Studies on caffeine consumption during pregnancy and ADHD are scarce, with conflicting results and several methodological difficulties such as lack of standardized outcome measures.
