There are papers by Gard and Lavallee that address this directly

The papers by Gard and Lavallee are not present in the retrieved evidence, so I cannot confirm what they specifically found about urinary incontinence and exercise engagement in midlife women.

The studies that were retrieved focus on treatment, not on the barrier question. One study of 125 new female fitness club members found that about 17% had incontinence at enrollment, and that prevalence stayed flat over 12 months of regular exercise [3]. That suggests incontinence does not necessarily stop women from joining a gym, but it does not tell you how many avoid exercise entirely because of it. Another study in young women found that high-volume competitive training (over 7 hours per week) roughly doubled the risk of incontinence compared to low-volume exercise [1]. That is the opposite causal direction: exercise can cause or worsen the condition, especially high-impact activity.

What the evidence does show is that pelvic floor muscle training (PFMT) can reduce incontinence symptoms. In a 2022 study of perimenopausal women, PFMT improved quality-of-life scores in physical activity, social relationships, and traveling domains [2]. A 2020 study found that among women with incontinence at 12 months, 82% were not doing regular PFMT [3]. That gap suggests many women do not know about or use the one intervention that could help them stay active.

The evidence base here is thin on the exact question. No study in this retrieval compared exercise participation rates between midlife women with and without incontinence. No study measured how often incontinence causes women to stop or avoid specific types of exercise. The treatment studies are small, mostly quasi-experimental, and none tracked long-term exercise adherence as an outcome.

My call: the evidence confirms that incontinence is common and that PFMT can help, but it does not quantify how much incontinence reduces exercise engagement. Confidence: low for the specific question asked.
