Babini D, et al. - Researchers investigated risk factors for urinary incontinence (UI) in primiparous adolescents between 7 and 48 months after vaginal delivery. For this cohort study, sample size was estimated at 140 volunteers, considering the calculation for logistic regression, with 20 observation units for each of the 7 variables proposed in the theoretical model developed for the study. Episiotomy, large newborn for gestational age and less than six prenatal appointments were identified as risk factors for UI in primiparous adolescents after vaginal delivery. Based on observations, they suggest professionals working in maternal health care to pay particular attention to primigravid mothers, guide prenatal appointments, avoid routine episiotomy, and use obstetric practices recommended by the World Health Organization.
