73: Accuracy of bladder scanner measurements in patients with pelvic organ prolapse

Abstract

Subjects completed validated questionnaires, including incontinence [International Consultation on Incontinence QuestionnaireeUrinary Incontinence (ICIQ-UI), Incontinence Resource Use Questionnaire (IRUQ)] and physical activity surveys [Physical Activity Scale for the Elderly (PASE) questionnaire]. Weekly pad usage was determined from the IRUQ. Physical activity was also directly recorded by accelerometer for one week. We examined UI severity (measured by ICIQ or number of pads used) in women with high versus low levels of physical activity and sedentary time using t-test and Wilcoxon rank sum. Linear regression was used to examine relationships between activity measurements and incontinence severity. Spearman's correlation was used to test associations between accelerometer and questionnaire data. RESULTS: Thirty-six subjects were included. Both accelerometer and physical activity questionnaires revealed high prevalence of sedentary behavior and low levels of physical activity in this population. Overall 89% of subjects were highly sedentary. Active time was mostly spent in light intensity activities. Compared to subjects in the 25 th quartile, those in 75 th quartile for moderate and vigorous physical activity duration, step counts, and daily MET rate (measured by accelerometer) had significantly less pad use (p¼0.03, 0.004, and 0.04, respectively). There was a non-significant trend towards greater pad use in those with higher sedentary bout time (p¼0.058). Urinary incontinence scores were not significantly different in women with high versus low physical activity and sedentary bout time (p>0.05). Greater daily step counts and increased total time spent in any level of activity was associated with decreasing pad use (p¼0.045). When comparing accelerometer to physical activity questionnaire, there was no correlation in measures of sedentary or active behavior between the two methods. CONCLUSION: Increased physical activity was significantly associated with decreased use of pads for UI. Sedentary activity showed a nonsignificant trend towards greater pad use. Intervention for UI may be beneficial for increasing physical activity in older adults. The physical activity questionnaire correlated poorly with accelerometer data and likely captures a separate construct of physical activity.
