However, the link between chronotype and depression in the general adolescent population, independently of poor sleep and prior mental health problems, remains unclear.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This study investigated the association between time\u2010to\u2010sleep (TTS) and depressive symptoms in middle adolescence (age 14\u00a0years) using data from a large, nationally representative birth cohort from the UK. The relationship between TTS and self\u2010reported number of depressive symptoms was adjusted for individual, family, and neighborhood characteristics, including sleep quality, earlier mental health, diet and family meal routines, body\u2010mass index, screen time, physical activity, chronic illness, special educational needs, peer victimization, socioeconomic status, maternal mental health, area safety and the built environment (air pollution).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>An \u201cevening\u201d chronotype was positively associated with depressive symptoms, and biological sex moderated this association\u2014with eveningness being more strongly related to depressive symptoms in females. TTS inconsistency between non\u2010school and school nights was associated with depressive symptoms and sleeping later on non\u2010school nights predicted fewer depressive symptoms. The results were robust to further sensitivity analyses that used the sleep midpoint on non\u2010school nights and controlled for sleep duration.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Limitations<\/jats:title>\n                    <jats:p>This was a correlational study.
