In‐home salivary melatonin collection: Methodology for children and adolescents

In‐home salivary collection quality and adherence to a prescribed collection methodology for evaluation of dim light melatonin onset (DLMO) is unknown in children. Primary aims of this study were to 1) describe a novel family centered methodology for in‐home salivary collection; 2) determine the acceptance and feasibility of this methodology; 3) measure adherence to collection instructions; and 4) identify patterns between participants’ age and quality of samples collected. After receiving instructional handouts from the study team, families utilized in‐home salivary melatonin collection. Participants (N = 64) included 39 children (21 female, mean age 9.5 ± 1.61 years) and 25 adolescents (11 female, mean age 15.9 ± 2.12 years) with craniopharyngioma. Participants were 90% adherent to collection schedule, and 89% of the samples collected were of sufficient quantity and quality, with no differences found between age (child vs. adolescent) and melatonin sample quantity and quality. In‐home saliva collection provides an acceptable and feasible method to collect salivary melatonin and biomarkers in children and adolescents.
