Comparison of body composition and overactive bladder symptoms in overweight female university students
Abstract
Objectives: To compare body composition in young overweight women with OAB compared to women without OAB, and to determine the severity of the symptoms of OAB, as well as to investigate the impact of OAB on quality of life. Study Design: Cross-sectional study.
The sample consisted of 1932 enrolled women classed as overweight (BMI:25-29.9).From this sample, 276 women were recruited. Of these, 206 women with an average age of 30.6 +/- 20.4 years and an average BMI of 25.8 +/- 3.0 were confirmed to be overweight.
We used the Voiding Diary, the Overactive Bladder Questionnaire(OAB-q),and the Incontinence Quality of Life (I-QoL) scale. Body composition was measured using direct segmental multi-frequency bioelectrical impedance analysis, with assessment of: skeletal muscle mass(kg)(SMM), body fat mass (kg)(BFM), body fat percentage (%)(BFP), visceral fat area (cm(2)/level)(VFA), and waist to hip ratio(WHR).
Results: The voiding diary and OAB-q results confirmed OAB in 102 women. There was no significant difference in BMI between groups.
The body composition analysis showed significant differences in BFP, VFA, and WHR, with higher values in the OAB group(p < 0.01). SMM, however, was higher in the group without OAB(p < 0.01).
Recorded I-QoL scores showed worse parameters in the OAB group(p < 0.001). Women with a body fat percentage above 32% have a 1.95 times greater chance of developing OAB.
Odds ratio [OR] = 1.95,(95%CI:1.09-3.52,p < 0.02). Conclusion: Body fat percentage, visceral fat area, and waist to hip ratio were significantly higher in overweight women with OAB, compared with women without OAB and a comparable BMI.
