Results: The estimated prevalence of MDD significantly increased among adolescents from 4% (95% CI 3–6%) at 13 years of age to 19% (95% CI 15–24%) at 16 years of age. From the age of 13, males were significantly less likely to have a diagnosis of MDD than females with the maximum sex difference occurring at the age of 15 (OR 0.24, 95% CI 0.13–0.47). All lifestyle risk factors were at some point significantly associated with MDD, but these associations did not differ by sex, except for body mass index. Discussion: These findings suggest that interventions designed to prevent the development of depression should be implemented in early adolescence, ideally before or at the age of 13 and particularly among young females given that the prevalence of MDD begins to rise and diverge from young males. Interventions should also simultaneously address lifestyle risk factors and symptoms of major depression.]]> Mon 21 Nov 2022 14:57:46 AEDT ]]> The Health4Life e-health intervention for modifying lifestyle risk behaviours of adolescents: secondary outcomes of a cluster randomised controlled trial https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:55399 Fri 24 May 2024 11:50:51 AEST ]]> Measurement Properties of Smartphone Approaches to Assess Physical Activity in Healthy Young People: Systematic Review https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51373 Fri 01 Sep 2023 13:41:09 AEST ]]>
