Predictors of sleep pattern disturbances. Results from a third-level university hospital

INTRODUCTION: Obesity is considered an epidemic condition. It is related to the increased prevalence of chronic degenerative diseases, but there are no studies in the Mexican paediatric population on its relationship with sleep disorders. AIM OF THE STUDY: We sought to determine the prevalence of sleep disorders in paediatrics, as well as factors for their development. MATERIAL AND METHODS: An observational, analytical, retrospective study, was performed including patients aged 2 to 16 years, between March 2019–2021. The Paediatric Sleep Questionnaire was used to assess the presence of sleep disorders. RESULTS: Sixty-four patients were included, 27 (42.18%) of whom had sleep disorder criteria. Among these, obesity, i.e. weight percentile ≥ 75 and body mass index percentile ≥ 93.5, was a risk factor. Normal weight was protective. CONCLUSIONS: Obesity in paediatric patients may favour the appearance of sleep disorders; screening could favour early diagnosis, correct treatment, and better life quality.
