Summary

This study looks at whether the position a woman gives birth in (lying on her back, upright, or on her side) can help prevent stress urinary incontinence (leaking urine when coughing or sneezing) after childbirth. Researchers will follow 669 first-time mothers, ages 20-35, who plan a vaginal delivery. Pelvic floor function will be checked 6 weeks after birth to see which position leads to better outcomes.
