Resumen
BACKGROUND SLEEP DURATION MAY BE A RISK FACTOR FOR COGNITIVE IMPAIRMENT. AIM TO INVESTIGATE THE ASSOCIATION BETWEEN SLEEP DURATION AND COGNITIVE FUNCTION IN CHILEAN OLDER ADULTS. MATERIAL AND METHODS WE ANALYZED INFORMATION FROM 1,384 PARTICIPANTS AGED > 60 YEARS PARTICIPATING IN THE NATIONAL HEALTH SURVEY 2009-2010 WHO WERE ASSESSED WITH THE MINI MENTAL STATE EXAMINATION (MMSE) AND SELF-REPORTED THEIR AVERAGE DAILY SLEEP HOURS. LOGISTIC REGRESSION ANALYSIS WAS PERFORMED TO INVESTIGATE THE ASSOCIATION BETWEEN MMSE AND SLEEP DURATION. RESULTS COMPARED TO THOSE PARTICIPANTS WHO REPORTED SLEEPING 7 HOURS PER DAY, THOSE THAT REPORTED SLEEPING < 5 HOURS HAD A HIGHER ODD FOR COGNITIVE IMPAIRMENT (ODDS RATIO (OR): 3.66 [95% CONFIDENCE INTERVALS (CI: 1.69; 7.95], P < 0.01). SIMILARLY, THOSE WHO REPORTED SLEEPING > 8 HOURS PER DAY ALSO SHOWED A HIGHER ODD FOR COGNITIVE IMPAIRMENT (OR: 2.56 [95% CI: 1.32; 4.95], P < 0.01). THIS ASSOCIATION WAS EVEN STRONGER FOR PEOPLE WHO REPORTED MORE THAN 10 HOURS OF SLEEP PER DAY (OR: 4.46 [95% CI: 1.32; 4.95], P < 0.01). CONCLUSIONS LONG AND SHORT SLEEP DURATION IS ASSOCIATED WITH COGNITIVE IMPAIRMENT IN OLDER ADULTS IN CHILE INDEPENDENT OF MAJOR CONFOUNDING FACTORS.
