Differences in weight status among Australian children and adolescents from priority populations: a longitudinal study
Authors' conclusion
Our findings identified key population groups at higher risk of overweight and obesity in childhood and adolescence. Prevention efforts should prioritize these groups to avoid exacerbating inequalities in healthy weight in childhood.
