Implication

Cross-sectional study finds frequent fast-food intake associated with higher body mass index in children, suggesting age-specific dietary impacts.

Key Points

To determine whether reported fast-food consumption over the previous year is associated with higher body mass index in children and adolescents across multiple countries.
Analyzed data from the multicentre, international cross-sectional ISAAC Phase Three study, comprising 72,900 children aged 6–7 years across 17 countries and 199,135 adolescents aged 13–14 years across 36 countries.
Assessed fast-food frequency via questionnaires categorizing consumption as infrequent (never/occasionally), frequent (1–2 times weekly), or very frequent (≥3 times weekly).
Applied general linear mixed models to assess associations with body mass index, adjusting for country-level Gross National Income per capita, measurement method, age, and sex.
Frequent and very frequent fast-food consumption was reported in 23% and 4% of children, and 39% and 13% of adolescents, respectively.
Children consuming fast food frequently and very frequently had a body mass index 0.15 kg/m² and 0.22 kg/m² higher, respectively, than infrequent consumers (p < 0.001).
Adolescents showed lower body mass index with frequent and very frequent consumption compared to infrequent consumption (males: -0.14 kg/m² and -0.28 kg/m²; females: -0.19 kg/m²; p < 0.001 for all).
