Sleep apnea sufferers more likely to have unhealthy food
Washington, October 15 : A new study has revealed that people suffering from severe
obstructive sleep apnea, a sleep disordered breathing condition, are more likely to
consume unhealthy food, which may be a factor contributing to greater cardiovascular
morbidity and mortality.
Published in the Journal of Clinical Sleep Medicine, a research article says that these
findings were most evident among women.
Dr. Stuart Quan, division of sleep medicine at Harvard Medical School, said: "We found
that persons who had severe obstructive sleep apnea ate a diet that was unhealthy with
increased intake of cholesterol, fat and saturated fatty acids."
During the study, the researchers observed that all participants with extremely severe
SDB, or those with respiratory disturbance index (RDI) above 50 disruptions per hour,
consumed 88.16 more milligrams of cholesterol per day as compared to those who had less
severe OSA.
Women with severe SDB, on average, consumed 21.96 more grams of protein, 27.75 more
grams of total fat, and 9.24 more grams of saturated fatty acids.
The researchers said that the results remained significant after controlling for BMI,
age, and daytime sleepiness.
They said that among the 320 participants, increasing RDI severity was associated with
greater consumption of cholesterol, protein and trans-fatty acids.
According to the team, there also was a trend towards greater ingestion of total
saturated fatty acids and total fat, but not carbohydrates, sucrose or dietary fiber.
The researchers said that with the exception of cholesterol, such associations were
primarily observed in women.
They said that the mechanism producing the higher dietary consumption of unhealthy
nutrients in persons with extremely severe SDB seemed to exaggerate behaviors already
observed among obese women.
In their study report, the researchers say that poor sleep quality, a consequence of
OSA, may result in a compensatory increase in caloric intake in an effort to boost energy
levels, which promotes weight gain.
Based on their observations, the researchers said that their study provided important
new information on the dietary habits of people with OSA, which might be another mechanism
through which SDB leads to serious health conditions like cardiovascular disease,
hypertension and stroke.
