Researchers at the University of Bari, Italy screened over 800 boys and girls (average age 7.3 years) and categorized them into non-snorers, occasional snorers or habitual snorers. Almost 25% of subjects were either overweight or obese. The children categorized as habitual snorers and who failed an oximetry study, underwent polysomnographic monitoring (also known as a sleep study) for sleep disordered breathing..
The researchers found the frequency of habitual snoring was significantly higher in obese subjects than in overweight and normal-weight children. Although only 1.7% of children were diagnosed with obstructive sleep apnea syndrome (OSAS), the findings suggest that there is a higher incidence of OSAS in over-weight children.
According to the research published in the journal CHEST, the researchers in Italy found that obesity is associated with childhood snoring.
