Study N Follow-up
(months)		 BMI (or wt) Δ Δ in prevalence
of UI episodes		 Other outcomes
Deitel et al
(66), 1988		 138 ? 124 to 79 kg 61.2% to 11.6%
(P < 0.001)		 After wt loss, infertility,
menstrual irregularities
and obstetric
complications improved

33.1 (131.5 to
88.1 kg)		 92.3% to 23.1%
(P = 0.004)		 Improvements seen in:

significantly associated
with decrease in BMI
