Lamerton TJ, Mielke GI, Brown WJ, et al. - In view of current evidence suggesting overweight and obesity as relevant risk factors for urinary incontinence in women, researchers sought to compare prevalence rates of urinary incontinence and high BMI in two cohorts of young women. In addition, they examined correlations between changes in BMI and urinary incontinence using analysis of combined data from the two cohorts and determined the correlations between physical activity and urinary incontinence, with adjustment for BMI. Two cohorts of young women in the Australian Longitudinal Study of Women’s Health (n = 16,065), born 17 years apart: 1973-78 (Cohort 1) and 1989-95 (Cohort 2), were assessed for data. Both cohorts showed an increase in rates of obesity over 4 years. Given that obesity rates are likely to raise further with age and parity, a strong correlation between obesity and urinary incontinence in young women is suggested to be a public health concern. Findings suggested the potential lowering effects of physical activity on the obesity-incontinence relationship, which merit further investigation.
