Depression in childhood and adolescence
Research on adolescent depression focuses on two key areas: (i) understanding the female excess in depression that emerges during adolescence; and (ii) identifying risk factors for adolescent depression.
Girls experience a rise in rates of depression and depressive symptoms in early adolescence, and by the mid-teens are twice as likely to experience an episode of depression compared with boys. Research conducted within the Centre has identified that girls who experience earlier onset menarche and more advanced pubertal development than their peers are at greater risk of developing depressive symptoms in adolescence. Ongoing research is examining whether timing of menarche is a causal risk factor for depression in adolescence.
Other work focuses on the role of individual factors in childhood (e.g. early temperament), family environmental factors (e.g. parenting, maternal depression) and childhood adversities (low socioeconomic status, father absence, bullying) in the aetiology of adolescent depression, as well as understanding the role of modifiable risk factors (such as physical activity and obesity) that may inform prevention strategies.
