This review examines the determinants of fruit and vegetable consumption among children and adolescents, focusing on quantitative studies. The authors conducted a comprehensive literature search in Medline and PsycINFO, identifying 98 papers that met the inclusion criteria. The review found that gender, age, socioeconomic position (SEP), preferences, parental intake, and home availability/accessibility are the most consistently supported determinants of fruit and vegetable intake. Girls and younger children tend to have higher or more frequent intake than boys and older children. Socioeconomic position, preferences, parental intake, and home availability/accessibility are positively associated with intake. The review highlights the need for more international comparative, longitudinal, theory-based, and multi-level studies that consider both personal and environmental factors. Despite the lack of consistent evidence for many determinants, the review provides recommendations for practice, emphasizing the importance of interventions to promote fruit and vegetable intake, especially among lower SEP groups and boys. The review also identifies areas where research is lacking, such as the influence of national and community-level factors, and suggests improvements in design and methodology for future studies.This review examines the determinants of fruit and vegetable consumption among children and adolescents, focusing on quantitative studies.
