Participants: N=574 Dutch young adults (18–35 years old).Measurements: Participants completed a survey on eating and sleep habits including the Eating Disorder Screen for Primary care (ESP) and SLEEP-50 questionnaire subscales for sleep apnea, insomnia, circadian rhythm disorder (CRD), and daytime functioning.SLEEP-50 outcomes of participants who screened negative (≤2) and positive (>2) on the ESP were compared.
In addition, SLEEP-50 scores of groups of participants with different ESP T/T House Loft Bed scores (0–4) and different BMI groups (ie, underweight, healthy weight, overweight, and obese) were compared using nonparametric statistics.Results: Almost 12% (n=67) of participants screened positive for having an eating disorder.Relative to participants without eating disorders, participants who screened positive Diet Supplements for eating disorders reported significantly higher scores on sleep apnea (3.
7 versus 2.9, P=0.012), insomnia (7.
7 versus 5.5, P<0.0001), CRD (2.
9 versus 2.3, P=0.011), and impairment of daytime functioning (8.
8 versus 5.8, P=0.0001).
ESP scores were associated with insomnia (r=0.117, P=0.005), sleep apnea (r=0.
118, P=0.004), sleep quality (r=−0.104, P=0.
012), and daytime functioning (r=0.225, P<0.0001), but not with CRD (r=0.
066, P=0.112).BMI correlated significantly with ESP scores (r=0.
172, P<0.0001) and scores on sleep apnea (r=0.171, P<0.
0001).When controlling for BMI, the partial correlation between ESP and sleep apnea remained significant (r=0.10, P=0.
015).Conclusion: Participants who score positive for eating disorders scored significantly higher on sleep disorder scales, and reported significantly more impairment of daytime functioning.Keywords: eating disorders, sleep disorders, insomnia, apnea, circadian rhythm disorder, daytime functioning.
