Ie. Nygaard et Jh. Lemke, URINARY-INCONTINENCE IN RURAL OLDER WOMEN - PREVALENCE, INCIDENCE ANDREMISSION, Journal of the American Geriatrics Society, 44(9), 1996, pp. 1049-1054
OBJECTIVES: To determine the prevalence, incidence, and remission rate
s of urinary incontinence in a large group of older women over a 6-yea
r time span and to assess factors associated with incontinence inciden
ce and remission. DESIGN: Longitudinal cohort study SETTING: Two rural
counties in Iowa PARTICIPANTS: 2025 women aged 65 years or older resi
ding in rural Iowa, enrolled in the Iowa 65+ Rural Health Study of EPE
SE (Establishment of Populations for Epidemiologic Studies of the Elde
rly) were interviewed in person annually for 6 years; specific respons
es to queries about urinary incontinence were given at baseline, 3-, a
nd 6-year intervals. MEASUREMENTS: Conditional multivariate logistic r
egression analysis was done to assess the relationship between inconti
nence symptoms and various factors previously found to be related to i
ncontinence. RESULTS: The baseline prevalence of urge incontinence was
36.3%, and of stress incontinence it was 40.3%. For urge incontinence
,the 3-year incidence and remission rates between the third and sixth
years were 28.5% and 22.1%, respectively. For stress incontinence, the
3-year incidence and remission rates between years 3 and 6 were 28.6%
and 25.1%, respectively. Seventy-six percent and 84% of women who rep
orted no urge or stress incontinence, respectively, at the baseline in
terview were continent at both follow-up interviews. The only signific
ant factors related to changes in incontinence status were age, which
was associated with an increased incidence of urge incontinence (OR 1.
11, P = .017, 95% CI 1.019-1.203), and improvement in activities of da
ily living, which was associated with a increased remission of urge in
continence (OR 0.50, P = .015, 95% CT 0.28-0.9) CONCLUSION: In some ol
der women, urinary incontinence is a dynamic state, with women moving
back and forth along a continuum between continence and incontinence.
These results are tempered by limitations of the study, which include
its questionnaire design and lack of ability to detect potential treat
ment effect.
