EL = 2+
Investigate the prevalence of stress or urge UI in past participants in long-term high impact exercise (gymnastics or track and field) compared with low impact exercise (swimming)104F, past USA OlympiansPrevalence of stress or urge UI according to prior participation in high or low-impact exerciseNo significant differences:
Urge UI: 34% high impact vs 17% low
Stress UI: 41% vs 50%
Funding: none declared.
BMI reported to be a risk for regular stress and urge UI.
Eliasson 2005216Cohort
EL = 2+
To describe physical activity and urinary leakage before, during and after the first childbirth725 enrolled, 665 (81%) answered both questionnaires*F mean age 28 (17–43) in their first pregnancy. Mean BMI 22.5 (range 16.6–41.3)
The physical activity/exercises were classified according to their impact on the pelvic floor, and the women were divided into three groups: high-impact exercise (n = 327), low-impact exercise (n = 84) and the inactive group (n = 254)
Prevalence39% before pregnancy: 44% in high-impact group, 30% low-impact, and 35% in no activity grp
62% during pregnancy: 64% in high-impact group, 60% low-impact, and 63% in no activity grp
75% at 1 year post-partum
Funding: Centre for healthcare sciences Karolinska Institutet, Stockholm.
*women answered one questionnaire during the 36th gestation week and another 1 year post-partum.
High-impact exercise = gymnastics, running, jumping, dancing, ball sports and strength training.
Low-impact = walking, bicycling, swimming, riding.
