Abstract
Introduction and hypothesis: Urinary incontinence (UI) is associated with body mass index (BMI) and may be influenced by depressive symptoms. This study was aimed at assessing the relationship between BMI and UI risk and frequency in adult women, with a focus on depressive symptoms, measured by Patient Health Questionnaire-9 (PHQ-9) score, as a potential mediator.
Methods: Data from 6107 adult women in the National Health and Nutrition Examination Survey from 2005 to 2018 were analyzed. Weighted multivariable-adjusted regression analysis determined odds ratios (ORs) and 95% confidence intervals (CIs) for BMI-UI associations. Restricted cubic spline (RCS) analysis evaluated nonlinear relationships, and causal mediation analysis examined the mediating role of depressive symptoms. Subgroup analyses were stratified by PHQ-9 score.
Results: Higher BMI was associated with increased UI risk and frequency. When BMI was categorized into quartiles, UI risk progressively increased from Q2 to Q4. In the fully adjusted model, OR for UI risk in Q4 vs Q1 was 2.53 (95% CI 1.83, 3.52; p < 0.001), with a significant trend across quartiles. RCS analysis indicated a nonlinear relationship, with increased UI risk, particularly at BMI levels above 30. Depressive symptoms were independently associated with higher UI risk and frequency, with significant mediation effects. Mediation analysis revealed that PHQ-9 score accounted for approximately 6.8% of the effect of the BMI on UI risk and 6.5% on UI frequency (both p < 0.001).
Conclusions: Elevated BMI and depressive symptoms are independently associated with increased UI risk and frequency among adult women. The mediation effect of depressive symptoms underscores the importance of addressing mental health and weight management to reduce UI risk. These findings advocate a holistic approach to UI prevention and treatment, integrating physical and mental health strategies.
期刊介绍：
The International Urogynecology Journal is the official journal of the International Urogynecological Association (IUGA).The International Urogynecology Journal has evolved in response to a perceived need amongst the clinicians, scientists, and researchers active in the field of urogynecology and pelvic floor disorders. Gynecologists, urologists, physiotherapists, nurses and basic scientists require regular means of communication within this field of pelvic floor dysfunction to express new ideas and research, and to review clinical practice in the diagnosis and treatment of women with disorders of the pelvic floor. This Journal has adopted the peer review process for all original contributions and will maintain high standards with regard to the research published therein. The clinical approach to urogynecology and pelvic floor disorders will be emphasized with each issue containing clinically relevant material that will be immediately applicable for clinical medicine. This publication covers all aspects of the field in an interdisciplinary fashion
