Is there a connection between sleep deprivation and obesity?

The startling statistic today is that more than one-third of American adults are obese and childhood obesity has more than tripled in the past 30 years. Doctors know there are several factors behind obesity including: more sedentary lifestyles (lack of regular physical activity) and excessive caloric intake in addition to a person’s genes and their environment. They’ve also noted a connection between the fact that Americans are sleeping less and they have begun studying whether sleep deprivation and obesity are connected.

In the past our ancestors slept about nine to ten hours a night and we are now sleeping, on average, seven hours. Researchers found that sleeping less than six hours a night increased the likelihood of obesity. They also found a connection between obesity and going to sleep after midnight.  A study conducted in 2002 found that increases in body mass index (BMI) occurred in individuals when they habitually got less than seven hours of sleep a night.  Researchers found that overweight and obese individuals slept less hours per night than individuals who were not obese.

As children sleep less, obesity levels rise. A study in the British Medical Journal found that short sleep duration at age 30 months is a predictor of obesity in children by the time they reached seven years of age. The study leads researchers to believe that poor sleep could have a permanent impact on the hypothalamus – the part of the brain that regulates appetite and energy.

Individuals who slept less than four hours a night for a period of one week experienced impaired glucose tolerance – a precursor to diabetes – they also experienced hypertension and changes in hormones related to weight gain. Researchers found the changes were reversible once the individuals returned to their normal sleep times.

Obesity in children raises other concerns as well. The increase in obesity has been tied to increased incidence of sleep apnea in these individuals. The Center for Disease Control conducted a 20-year study of obesity-associated diseases among children aged six to 17-years-old and found that among those who had obesity related diseases, an increased incidence of 436% of sleep apnea was noted.

In adults, an estimated 18 million suffer from sleep apnea and this is often associated with those who are overweight. “As the person gains weight, especially in the trunk and neck area, the risk of sleep-disordered breathing increases due to compromised respiratory function,” say Margaret Moline, PhD, and Lauren Broch, PhD, two sleep specialists at New York Weill Cornell Medical Center.

Client Reviews

"I recommend them highly!! I took my 2 year old daughter for a sleep study and was very impressed. Our sleep technician was amazing with her, very patient and kind. The DVD we brought to watch while getting her hooked up got stuck in the TV and they vowed to return it. We got a call the next day checking on our daughter and saying how sweet she was, they mentioned the DVD. Several days later, we received the DVD plus a new copy of the Lion King with a nice note. They are very good at what they do and if they can make a 2 year old feel at ease, they can probably do the same with anyone!!"

"I was especially impressed with Andrew the Respiratory Therapist who reviewed my study with me and answered my questions. Andrew thoroughly explained everything about the Cpap machine-from start to finish. I never felt rushed and was assured I could contact him with any additional questions or needs. Andrew told me he would follow up with a call in a week and he did. I believe this center performed the study appropriately and the added benefit of having Andrew teach me about the machine and what to expect was a bonus."
