Study Objectives
Little is known about the type and severity of sleep disturbances in the pediatric chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) population, compared with healthy adolescents. Using a range of objective and subjective measures, the aim of this study was to investigate sleep quality, the relationship between objective and subjective measures of sleep quality, and their associations with anxiety in adolescents with CFS/ME compared with healthy controls.

Methods
Twenty-one adolescents with CFS/ME aged 13 to 18 years (mean age 15.57 ± 1.40), and 145 healthy adolescents aged 13 to 18 years (mean age 16.2 ± 1.00) wore actigraphy watches continuously for 2 weeks to collect a number of objective sleep variables. The Pittsburgh Sleep Quality Index was used to obtain a subjective measure of sleep quality. Anxiety was measured by the Spence Children's Anxiety scale.

Results
On average over the 2-week period, adolescents with CFS/ME were found to have (1) significantly longer objective sleep onset latency, time in bed, total sleep time, and a later rise time (all P < .005), and (2) significantly poorer subjective sleep quality (P < .001), compared with healthy adolescents. The CFS/ME patient group displayed higher levels of anxiety (P < .05), and in both groups, higher levels of anxiety were significantly related to poorer subjective sleep quality (P < .001).

Conclusions
This study provides objective and subjective evidence of sleep disturbance in adolescents with CFS/ME compared with healthy adolescent controls.

Chronic fatigue syndrome (CFS), also called myalgic encephalomeyelitis (ME), is a chronic illness that affects up to 2.5 million Americans and is characterized by extreme fatigue that doesn’t improve with rest.

A recent study published in the Journal of Clinical Sleep Medicine has found that teens with chronic fatigue syndrome experience more sleep disturbances than those in a healthy control group, which could lead to poorer quality of life and impaired development. Other studies have shown the illness to also be linked to obesity, eating difficulties, and chronic widespread pain.

“Pediatric CFS/ME is a debilitating and poorly understood condition that can cause an adverse functional impact during a critical phase of development, typically adolescence between 10 and 19 years,” says Elisha Josev, lead author of the study. “The consequences of this condition can be different in adolescents compared to adults, including impacts on school functioning and school attendance, socializing, and vocational prospects.”
