Abstract
Background:Urinary incontinence and impaired bone health are significant health problems among the elderly. We evaluated the impact of urinary incontinence on bone health in the elderly.Material and Methods:Our study used data from the Korea National Health and Nutrition Examination. We included 901 women aged ≥ 65 years. The bone mineral density was measured by dual-energy X-ray absorptiometry. Impaired bone health was characterized by lumbar spine, femoral neck, or total femur T-scores of ≤ −1.0 SD. Each participant’s incontinence status was recorded using constructed questionnaires.Results:The prevalence of self-reported urinary incontinence in the women aged ≥ 65 years was 9.5%. After adjustments for age, height, and weight, the T-scores for the lumbar spine of the urinary incontinence and the no urinary continence groups were −2.48 ± 0.11 and −2.37 ± 0.03, respectively and didn’t show the difference between them (p = 0.390). Likewise, the T-scores for the total femur and femoral neck were not significantly different. After adjusting for covariates, we found no statistically significant association between impaired bone health with urinary incontinence.Conclusions:This study found urinary incontinence was not an independent risk factor of impaired bone health in the elderly women.
Highlights
The International Continence Society defines urinary incontinence as “the complaint of any involuntary leakage of urine” [1]
We examined the adjusted Odds ratio (OR) for impaired bone health of the total femur, femoral neck, and lumbar spine in the two groups
This study has important meaning because it is the first domestic study of the association between urinary incontinence and bone health that used Korea National Health and Nutrition Examination Survey (KNHANES) data. In this representative population-based study, we showed that 9.5% of the elderly women reported inconvenience due to urinary incontinence and only 3.0% were diagnosed as having urinary incontinence by a physician
Summary
The International Continence Society defines urinary incontinence as “the complaint of any involuntary leakage of urine” [1]. According to the current research, increased fat mass which was accurately measured by dual-energy X-ray absorptiometry is closely linked to urinary incontinence [5]. Urinary incontinence and impaired bone health are significant health problems among the elderly. We evaluated the impact of urinary incontinence on bone health in the elderly. Impaired bone health was characterized by lumbar spine, femoral neck, or total femur T-scores of ≤ −1.0 SD. Results: The prevalence of self-reported urinary incontinence in the women aged ≥ 65 years was 9.5%. After adjusting for covariates, we found no statistically significant association between impaired bone health with urinary incontinence. Conclusions: This study found urinary incontinence was not an independent risk factor of impaired bone health in the elderly women
