O048 The CF elephant in the adolescent room: a cross sectional study of sleep and mood in adolescents with cystic fibrosis

Background Mental health issues are of increasing burden within the adolescent CF population, with known impacts from sleep disturbance. There are limited studies examining mediators of this relationship. We aimed to investigate the relationship between sleep quality and mood in adolescents with CF alongside a range potential mediating factors including socioeconomic and family influences in adolescents. Study Design Adolescents with CF aged 10–18 and their parents at a Victorian tertiary paediatric CF centre were eligible. Adolescents-parent pairs cross sectionally completed age appropriate online questionnaires assessing sleep (Pediatric Daytime Sleepiness Scale, Sleep Disturbance Scale for Children), mood (Global Anxiety Disorder-7, Patient Health Questionnaire-9, Beck’s Depression Inventory, Brigid Jordan CF screen), health-related quality of life (CF Questionnaire-Revised), family dynamics (Family Assessment Device, Family Management Measure), CF respiratory symptoms (CF Respiratory Symptom Score), and treatment adherence. Socioeconomic status and impacts from pandemic lockdowns were also surveyed. Progress to date 45 CF adolescents-parent pairs have been recruited. Questionnaires have been distributed and awaiting return of results for analysis. Intended outcome and impact We anticipate demonstrating the known association between impaired sleep quality and elevated mood scores. We will also make commentary on associations with a range of social factors (family dynamics, socioeconomic status) as well as parental mental health. Discussion will also include impacts on treatment adherence, HRQOL and respiratory symptom scores. Results from this pilot will inform the upcoming AREST CF prospective longitudinal study where the bidirectional relationships between factors studied can be further explored.
