HABITUAL SNORING IN CHILDREN ASSOCIATED WITH POOR ACADEMIC PERFORMANCE
Habitual snoring in third-grade children was associated with poor academic performance on mathematics, science, and spelling in a large study of 1,129 German primary students. According to investigators, the research was the first to show a clear biological relationship between snoring frequency and the risk of poor academic performance. Of the 1,129 children for whom investigators had snoring information, 410 (36.3 percent) never snored and 605 (53.6 percent) snored occasionally. Eighty-nine youngsters (7.9 percent) snored frequently and 25 (2.2 percent) always snored. Snoring "always" was significantly associated with poor academic performance in mathematics, science, and spelling, while snoring "frequently" was significantly associated with low grades on mathematics and spelling. The investigators assessed snoring and intermittent hypoxia (inadequate amounts of available oxygen in the blood) using a parental questionnaire and nocturnal home oximetry. (In its most fundamental form, oximetry is a process designed to measure oxygen concentrations in the blood using an electrode placed on the finger or an earlobe.) The researchers found that children with intermittent hypoxia showed no independent association with poor academic performance, whereas the scientists did find a significant relationship between snoring and poor academic performance in children without intermittent hypoxia. The study appears in the second issue for August 2003 of the American Thoracic Society's peer-reviewed American Journal of Respiratory and Critical Care Medicine.

EXERCISE REDUCES THE DECLINE IN PULMONARY FUNCTION IN AGING MEN
In tests of male subjects over periods of up to 25 years, Finnish investigators found that higher levels of physical activity were associated with a slower rate of decline in pulmonary function with aging, along with lower mortality rates. T
