Almost 40% of firefighters suffer from at least one sleep disorder


Sleep problems could be a major factor in explaining why more than 60 percent of firefighter deaths are caused by heart attacks and traffic accidents, a new study published in The Journal of Clinical Sleep Medicine has found.

Researchers sampled almost 7,000 firefighters across the U.S. and examined how many tested positive for sleep disorders such as obstructive sleep apnea, insomnia, shift-work disorder and restless leg syndrome, the New York Times reports.

They found that 37 percent of firefighters suffered from at least one type of sleep disorder.

“Our findings demonstrate the impact of common sleep disorders on firefighter health and safety, and their connection to the two leading causes of death among firefighters,” said lead author Laura K. Barger. “Unfortunately, more than 80% of firefighters who screened positive for a common sleep disorder were undiagnosed and untreated.”

Barber’s team found that when compared with those who had a good night’s sleep, firefighters who had a sleep disorder were more likely to crash their car or fall asleep at the wheel.

Adult ferritin treatment threshold too high for kids with restless sleep

VITALSKey clinical point: For children with restless sleep, consider iron supplementation at a serum ferritin level of 20 mcg/L.Major finding: A serum ferritin threshold of 20 mcg/L is a better predictor of sleep restlessness in children than is the adult threshold of 50 mcg/L.

Data source: Review of 537 children (1-18 yrs) referred to the University of Michigan pediatric sleep clinic.

Disclosures: The study was supported by a grant from the Charles Woodson Fund for Clinical Research.

 MINNEAPOLIS – Using the adult treatment threshold for serum ferritin to guide treatment in children with restless sleep may lead to inappropriate iron supplementation.

In both adults and children, iron deficiency has been linked to the presence and severity of restless legs syndrome (RLS) and periodic limb movements of sleep (PLMS). For adults, a serum ferritin less than 50 mcg/L is the threshold commonly used to guide iron supplementation for patients with RLS or PLMS.
