  "abstract": "Introduction Children and young people (CYP) with obesity are at increased risk of obstructive sleep apnoea hypopnoea syndrome (OSAHS). Anecdotally, CYP with obesity may have poor sleep hygiene, characterised by modifiable behavioural factors that negatively influence sleep. The Complications of Excessive Weight (CEW) clinic was established to address the growing concern regarding CYP with obesity. CYP scoring >0.33 on the Paediatric Sleep Questionnaire (PSQ) are referred to the sleep service for a polysomnography (PSG) study and actigraphy. A high PSQ score increases the pre-PSG likelihood of OSAHS, though some questions could be consistent with sleep hygiene issues. This can be evaluated using PSG and actigraphy outcomes.Methods The data presented is the preliminary data of a service evaluation of CYP referred into the sleep service via the CEW clinic from November 2025 to February 2026. It includes 7 patients (5 female and 2 male) ages 9-17, with a BMI above the 99.6th centile. All patients had actigraphy and 4 have had a PSG in this timeframe.PSG and actigraphy are performed in accordance with the American Academy of Sleep Medicine guidelines. PSG measures nasal flow, electroencephalography, electrooculography, electrocardiography, oxygen saturation, chest and thoracic movement and transcutaneous carbon dioxide. The actigraphic device is worn for 2 weeks, providing average sleep onset and average sleep per 24-hour period.Results All 7 patients were found to have a late sleep onset on actigraphy respective of their age. 5 of these patients had reduced average sleep per 24-hour period (mean 7 hours 26 minutes, SD = 37 minutes). 1 patient was diagnosed with delayed sleep phase (average sleep onset of 03:40am).1 patient had a normal AHI of 0, 2 patients had an AHI of 3.2 (mild OSAHS) and 1 patient had an AHI of 33.9 (severe OSAHS). Of these, 3 patients had abnormal actigraphy.There was an incidental finding that 4/7 patients have learning difficulties.Conclusions As these are initial findings, increased patients in the cohort will be required to elucidate any significant findings. However, the findings in this cohort are in keeping with a sleep hygiene issue alongside OSAHS in some patients.",
