Seasonal trends in antidepressant prescribing, depression, anxiety, and self-harm in adolescents and young adults: an open cohort study using UK primary care data.

There were higher rates of antidepressant prescribing, depression, and anxiety at the start of the school year in adolescents. Support around mental health issues from GPs and schools should be focused during this period. Future studies should examine whether these results apply to younger children and develop interventions to lessen their impacts on adolescents.
