Feasibility, Acceptability and Effectiveness of the SOmNI Mobile Phone App for Sleep Promotion in Adolescents

2019-09-19 03:56:46 | BioPortfolio


This study evaluates the acceptability, feasibility, and efficacy of an intervention using wearable sensors and a mHealth application, SOmNI, to promote sleep for adolescents. The investigators hypothesize that a behavioural intervention delivered through a mobile app will be a cost-effective and accessible method of engaging adolescents in the self-management of sleep behaviours. Participants will be randomized to either the SOmNI Intervention group or the Control group. Participants receiving the SOmNI app will attempt to incrementally move their school night bedtime earlier in the evening.


Over 60% of adolescents sleep less than the 9 hours of sleep recommended for 13-18 year olds. Quality of life is reduced due to the daytime consequences of chronic sleep deprivation such as sleepiness, fatigue, low mood, and inattentiveness at school. Although this sleep debt occurs in otherwise healthy adolescents, it significantly increases their risk of development of the chronic health conditions (cardiovascular disease and depression) and forms of accidental injury (motor vehicle accidents) that place the greatest demands on our health care system. Despite increased recognition of adequate sleep as a key contributor to health, there exist few effective interventions to promote sleep in adolescents. This study is designed to determine compliance, feasibility and preliminary data on health outcomes (nocturnal sleep measured objectively by actigraphy; daytime sleepiness; anxiety; depression; unintentional injuries; morning school attendance). This study will be a pilot RCT, randomizing 76 adolescents to one of two groups (i.e. 38 per group). Study arms will include a control group and intervention group (activity monitoring device with custom application). Mobile health, user-friendly low-intensity interventions with wearable sleep sensors and tailored feedback may help many adolescents to increase the amount of sleep they achieve.

Medical and Biotech [MESH] Definitions

The state of being deprived of sleep under experimental conditions, due to life events, or from a wide variety of pathophysiologic causes such as medication effect, chronic illness, psychiatric illness, or sleep disorder.

Excessive periodic leg movements during sleep that cause micro-arousals and interfere with the maintenance of sleep. This condition induces a state of relative sleep deprivation which manifests as excessive daytime hypersomnolence. The movements are characterized by repetitive contractions of the tibialis anterior muscle, extension of the toe, and intermittent flexion of the hip, knee and ankle. (Adams et al., Principles of Neurology, 6th ed, p387)

A disorder characterized by recurrent apneas during sleep despite persistent respiratory efforts. It is due to upper airway obstruction. The respiratory pauses may induce HYPERCAPNIA or HYPOXIA. Cardiac arrhythmias and elevation of systemic and pulmonary arterial pressures may occur. Frequent partial arousals occur throughout sleep, resulting in relative SLEEP DEPRIVATION and daytime tiredness. Associated conditions include OBESITY; ACROMEGALY; MYXEDEMA; micrognathia; MYOTONIC DYSTROPHY; adenotonsilar dystrophy; and NEUROMUSCULAR DISEASES. (From Adams et al., Principles of Neurology, 6th ed, p395)

Periods of sleep manifested by changes in EEG activity and certain behavioral correlates; includes Stage 1: sleep onset, drowsy sleep; Stage 2: light sleep; Stages 3 and 4: delta sleep, light sleep, deep sleep, telencephalic sleep.

Dyssomnias (i.e., insomnias or hypersomnias) associated with dysfunction of internal sleep mechanisms or secondary to a sleep-related medical disorder (e.g., sleep apnea, post-traumatic sleep disorders, etc.). (From Thorpy, Sleep Disorders Medicine, 1994, p187)
