NCT04878198

Brief Summary

This RCT study aims to compare effectiveness physical exercise and melatonin supplement on treating sleep disturbance in children with ASD. A four-arm randomized controlled trial with equal allocation ratio to the three intervention groups (i.e., jogging; melatonin supplement, combine jogging and melatonin supplement) and one placebo-control group will be conducted . Actigraph device and sleep log will be used for sleep assessment. 6-sulfoxymelatonin from 24-h and first morning urinary samples. The investigators will monitor the changes of four sleep parameters (sleep onset latency, sleep efficiency, wake after sleep onset and total sleep duration) and the 24-h and first morning melatonin level throughout the whole study.

Outcome Measures

Primary Outcomes (7)

  • Sleep onset latency

    Sleep onset latency (length of time taken to fall asleep, expressed in minutes, SOL) will be objectively measured by a GT3X accelerometer

    10-week

  • Sleep efficiency

    Sleep efficiency (actual sleep time divided by time in bed, expressed as a percent, SE) will be objectively measured by a GT3X accelerometer.

    10-week

  • Wake after sleep onset

    Wake after sleep onset (length of time they were awake after sleep onset, expressed in minutes, WASO) will be objectively measured by a GT3X accelerometer.

    10-week

  • Sleep duration

    Sleep duration (total sleep in hours and minutes, SD) will be objectively measured by a GT3X accelerometer.

    10-week

  • Parental-assessed sleep quality

    Participants' sleep patterns will be logged by their parents using daily sleep diary.

    10-week

  • 24-h melatonin level

    All participants will be instructed to collect a 24-h urine sample. 6-sulfatoxymelatonin, a creatinine-adjusted morning urinary melatonin and representative of melatonin level, will be measured from the sample. The weekend has been chosen to allow the participants to stay at home for sample collection. All urine samples will be collected using 24-h urine bottles containing 0.1L of 0.5M hydrochloric acid as a preservative

    10-week

  • First morning void melatonin level

    All participants will be instructed to collect the first morning void urine sample. 6-sulfatoxymelatonin, a creatinine-adjusted morning urinary melatonin and representative of melatonin level, will be measured from the sample. All urine samples will be collected using small urine bottles containing 0.1L of 0.5M hydrochloric acid as a preservative

    10-week

Study Arms (4)

Jogging intervention

EXPERIMENTAL

This intervention will be a 10-week jogging program consisting of 50 sessions (5 sessions per week, 30 min per session) in each participating school. The jogging program is confined to morning sessions based on the favourable sleep outcomes from previous study. To counteract the possible influence of natural sunlight exposure, all jogging sessions will be confined to indoor setting. Each session will be conducted in an identical format with 5 minutes of warm-up activities, followed by 20 minutes of jogging (intervention), and 5 minutes of cool-down activities. Participants are instructed to jog at a moderate intensity level. The intensity level of jogging will be measured by heart rate monitor (Polar H1). Meanwhile, questionnaire will be given to the research staff assisting the jogging intervention to assess the adherence of the intervention at T2.

Behavioral: Jogging program

Melatonin supplement group

EXPERIMENTAL

Participants in this intervention group will undergo a 10-week melatonin supplement intervention period, where melatonin supplement (Natrol®, Chatsworth CA) will be provided 30 minutes before bedtime. The prescription time (i.e. 30 minutes before bedtime) and the dosage of 3mg will be used because these are optimal for most of the participants as suggested by Malow and colleagues. 1 mg and 9 mg are not suggested to ensure the effectiveness of the intervention while preventing the potential daytime sleepiness. Similar to the aforementioned intervention, adherence of the intervention will be assessed at T2.

Drug: Melatonin supplement intervention

Combination group

EXPERIMENTAL

Participants will receive the jogging program and supplemental melatonin dose with identical format as that in the intervention A and B (e.g., identical duration, identical manpower, identical warm-up and cool-down, identical dose, identical acclimation procedure before the intervention adherence of the intervention for this group will also be assessed at T2.

Behavioral: Jogging programDrug: Melatonin supplement intervention

Control group

NO INTERVENTION

Participants in the placebo control group will receive no jogging and melatonin supplement dosing activity. However, they will be given a placebo flavored similar to the melatonin supplement (compounded by Pharmacare, Mt. Juliet, NT®). Meanwhile, they will also be required to wear an actigraph to control for their physical activity level at the assessment points (i.e. T1, T2, and T3). They will be expected for following their daily routine without participating in any additional formal physical exercise training program throughout the whole study period (T1-T3). After T3, they will be assisted with jogging program to recognize their contribution as controls.

Interventions

Jogging programBEHAVIORAL

This intervention consists of 50 sessions of morning jogging sessions at moderate intensity level. Each intervention session will be administered by a trained research assistant assisted by student helpers. All the research staff (i.e. student helpers and research assistant) will be required to attend a workshop (see educational plan) to standardize the procedure on implementing the intervention, as well as handling and motivating their ASD partners. Motivation techniques in previous protocol will be used to enhance the compliance rate.

Combination groupJogging intervention

This intervention is a 10-week melatonin supplement intervention where melatonin supplement will be provided 30 minutes before bedtime.
