Sleep quantity and quality as a predictor of injuries in a rural population.
This study aimed to assess the association of sleep disturbance and injuries in a rural population of Iowa. Study participants were 1345 adults who were enrolled in the KCRHS. Sleep problems were assessed based on self-reports at the beginning of the study. Injury information was collected by telephone interviews an average of every 6 months from August 1999 to June 2004. Sleeping for less than 7.5 hours increased the risk for injuries by 61% (rate ratio, 1.61; 95% confidence interval, 1.21-2.15) compared with sleeping for 7.5 to 8.5 hours (reference). Snoring frequency/severity and daytime fatigue/sleepiness were not significant in predicting the risk for injuries. Alcohol consumption of 1 to 2 or more drinks per day increased the risk for injuries among those who had sleep problems. Having adequate hours of sleep is important in preventing injuries. Avoiding alcohol consumption would be especially helpful in reducing injuries among people with sleep disturbance.
