RELATIONSHIP BETWEEN NOCTURNAL URINARY FREQUENCY AND SLEEP DISTURBANCES IN AGED MEN

The relationship between nocturnal urinary frequency and sleep disturb ances is investigated in aged men in 12. rural towns in Kyoto and Shig a Prefectures. The subjects were 178 men who did not have diseases or symptoms that were likely to affect urinary condition or sleep. There were no significant differences in sleep disturbances, except sleep ma intenance, between the normal group (nocturnal urinary frequency below twice per night) and the abnormal group (nocturnal urinary frequency twice or more per night). In healthy aged men, nocturnal urinary frequ ency only caused disturbance in sleep maintenance, but did not cause a ny other sleep disturbance.
