Epidemiology of XXXX in an elderly ambulatory population.

@entity1 @entity281 @entity793
This study of @entity793 in elderly (mean age 85 years, range 68 to 103) Jewish subjects of mostly middle and upper class attempted to determine disease prevalence, define the turnover in infected subjects, and assess the relation between functional status and @entity281 . The prevalence of @entity793 (midstream clean-catch method) was assessed in 373 @entity1 and 150 @entity1 . It was higher in @entity1 (18.2 percent) than in @entity1 (6.0 percent) (p less than 0.001) and was more common in functionally impaired nursing home residents (23.5 percent) than in apartment house dwellers (12.1 percent) (p less than 0.01). In longitudinal studies, 260 subjects (184 @entity1 and 76 @entity1 ) had three urine culture surveys at six-month intervals. The cumulative percent infected on at least one survey was high ( @entity1 30.4 percent, @entity1 10.5 percent). However, persistence of the same organism on all three surveys was surprisingly infrequent ( @entity1 6.0 percent, @entity1 1.3 percent), and the turnover of infected and noninfected subjects was considerable. Persistence of @entity793 on all three surveys was significantly more common in nursing home residents (13.9 percent) than in apartment house dwellers (3.1 percent) (p less than 0.01). Thus, @entity793 is common in the elderly and appears related to functional status. However, the turnover of infected and noninfected subjects was high, and surprisingly, persistence was not found in most. The transient nature of @entity793 in most provides support against the treatment of asymptomatic @entity793 in the elderly.
