Factors associated with melatonin use in child sleep disturbance: a survey of Australian parents

Objective: Sleep disturbances are prevalent in Australian children and cause a significant amount of stress to both children and their parents. If sleep disturbances are left untreated, they can result in detrimental consequences to both child and parental wellbeing. While behavioural interventions are recognised as the gold standard treatment for paediatric insomnia, there is a growing use of melatonin from both prescription and non-prescription sources in paediatrics. However, empirical research on the efficacy and safety of melatonin for children is sparse, conflicting, and inconsistent. This first Australian study aimed to investigate correlates of melatonin use in a sample of children with sleep disturbance in Australia and assess whether melatonin is being administered to children contrary to Therapeutic Goods Administration Guidelines. Methods: An exploratory online study was undertaken with 318 parents of Australian children with sleep disturbance (95.30% females). Logistic regression, mediation and descriptive analysis were conducted. Results: As hypothesised, higher parental stress, older child age, and a diagnosis of ADHD were significantly associated with melatonin use in this sleep disturbed sample. Other potential correlates such as financial stress, number of household dependents, child sleep disturbance, and autism were not significantly associated with melatonin use in adjusted analyses. Conclusion: Findings show off-label melatonin use in children with sleep disturbance is prevalent. For the first time, this study showed an indirect path linking child sleep disturbances with melatonin use via parental stress. Overall, while the safety of melatonin use remains unknown, there is a clear need to mitigate parental stress to minimise potentially unmonitored and improper use of melatonin in children.
