Babies and Mobiles May Lead to ‘Daytime Dysfunction’

Parents of infants with sleep trouble have increased risk of daytime dysfunction, including work and driving performance. New Flinders research has also measured the effects of sleep disruption from waking up regularly to deal with text messages during the night.

The research was among the key presentations at the national Sleep DownUnder 2019 conference — and the international World Sleep 2019 Conference in Vancouver. Poor infant sleep deprives parents. The study found sleep-deprived parents are three times at risk of experiencing daytime dysfunction compared to the parents of infants without sleep problems.

Further, as infants continue to have sleep problems, the likelihood of parents reporting daytime dysfunction increases by 14 percent per month. Daytime dysfunction can impede activities, including driving and occupational performance, and with sleep problems prevalent in 20-30 percent of infants, potentially impacts a significant portion of parents.

Flinders University sleep researchers partnered with New York-based tech company Nanit for this new sleep research study that links infant sleep troubles and daytime dysfunction among parents. The paper — titled Are parents of infants with sleep problems at risk for daytime dysfunction?, by lead author Meg Pillion from Flinders University — was presented at the World Sleep 2019 Conference.

The study used Nanit’s smart baby monitors to track infant sleep quality across 619 families and automatically analyzed the data with its computer vision algorithm.

A Brief Infant Sleep Questionnaire was then used to measure the presence of infant sleep problems as reported by parents. To measure parents’ daytime dysfunction, researchers utilized a sub-component of the Pittsburgh Sleep Quality Index (PSQI).

Co-author Professor Michael Gradisar, Clinical Psychologist at the Child and Adolescent Sleep Clinic at Flinders University, says using the Nanit camera system and AI allows for objective measurement of both the infants’ sleep quality and parents’ behavior, adding:

Flinders University and Nanit are collaborating on another study to provide objective evidence demonstrating the link between parental involvement and deficient infant sleep, finding that parental night-time visits were more frequent for younger infants, as well as for infants with poorer sleep quality. Dr. Michal Kahn, a co-author on the study and a postdoctoral fellow at Flinders University, said:

One in five Aussies wake to text messages

Meanwhile, researchers at the Adelaide Institute of Sleep Health at Flinders University have found Australians routinely wake up to send and receive text messages long after the lights are out.

After questioning 2,044 adults about their use of electronic devices after going to sleep, the research found late-night texting and emailing regularly disturbs the sleep of Australians from adolescence and beyond. Lead researcher Dr. Sarah Appleton said:

These people were two to six times more likely to report adverse daytime functional outcomes due to sleepiness or a sleep problem, including having or nearly having a motor vehicle accident, work absenteeism and errors, falling asleep on the job, and missing social activities. Dr. Appleton said:

These outcomes were not limited to young adults, with adults 55 years and older experiencing device disturbance. The research team called for new public health strategies aimed across the age spectrum to encourage people to switch off, turn down, or relocate their electronic devices or phones to another room at bedtime.

The research was presented at Sleep DownUnder 2019, the annual conference of the Australasian Sleep Association, held October 17-19 at the International Convention Centre, Sydney.

Technology use at night, sleep quality and daytime disturbances: a screenshot of Australian adults by Dr. Sarah Appleton, Dr. Amy Reynolds, Dr. Tiffany Gill, Dr. Yohannes Adama Melaku, and Professor Robert Adams, who received funding from the Sleep Health Foundation.

Introduction: Technology/light emitting electronic device use and its relationship with health are well described in children and adolescent populations.

In adult populations, this is less well described. We determined demographic correlates of technology use during the night, in addition to associations with sleep quality and daytime disturbances in a representative sample of Australian Adults.

Methods: A cross-sectional national online survey of sleep health was conducted in 2019 (n=2044, age range 18-90). The sample demographic profile closely matched ABS estimates. Survey questions were derived from the 2002 U.S. and 2016 Australian Sleep Health Foundation Surveys.

Technology use was assessed by using the question: “In the past seven days, how often did you wake from sleep or were woken to send or receive text messages, email,s or other electronic communications?” Responses were categorized as not at all, one night, two, or three/most or all nights.

Results: Electronic communications during the night were reported by 31.4 percent of adults, with 12.7 p[ercent (n=251) reporting one night, and 18.7 percent (n=371) responding two or three or most/all nights. Bedroom technology included: computer (25 percent), mobile phone/phone (72 percent), tablet/iPad (33 percent), and television (43 percent).

Technology-related activities in the hour before sleep conducted 3 or more times/week included watching television (76 percent), doing work related to one’s job (14 percent), using the Internet (66 percent), and social media (49 percent) and all were significantly associated with electronic communications during the night.

Compared to those not sending/receiving texts/emails, communication ≥ 2 or 3 nights/week was significantly associated with perceptions of reduced sleep insufficiency and autonomy, and at least one symptom of difficulty initiating and maintaining sleep (55 percent cf 75 percent) and daytime disturbances (≥3 days/week in past month; 57 percent cf 85 percent), including measures of sleepiness, fatigue, mood, and attention problems.

In contrast, no significant association with self-rated health was seen. Adjusted for demographic factors, electronic communications ≥ 2 or 3 nights/week was significantly associated with male gender, age groups 18-24, 25-34, 35-44, and 45-54, and language other than English spoken at home.

Conclusion: Public health implications of not switching off devices at night are significant in terms of sleep quality and daytime psychosocial function. The younger age of those waking from sleep to text and email may mitigate the physical health impacts of sleep disruption.
