Abstract
OBJECTIVE: To assess pregnant women's knowledge, attitudes, and practices (KAP) regarding premature rupture of membranes (PROM) and associated factors. METHODS: A cross-sectional study was conducted at Beijing Friendship Hospital, Capital Medical University (Beijing, China) from January 10th, 2025 to February 28th, 2025. Using convenience sampling, pregnant women with gestational age ≥ 28 weeks who provided informed consent were recruited, while those with abnormal pregnancy/adverse outcomes, psychological/mental illness, or current PROM/PPROM at enrollment were excluded. Data were collected via an online questionnaire, and statistical analyses were performed using R (version 4.3.2) and Stata (SEM). RESULTS: A total of 422 participants were included. Mean (SD) knowledge, attitude, and practice scores were 36.32 (7.91), 20.76 (3.61), and 6.91 (1.50), respectively. Using the 60% cutoff, 81.04% had good knowledge, 45.02% had positive attitude, and 84.36% had proactive practice. Proactive practice was associated with higher knowledge (OR = 1.09, 95% CI 1.04, 1.13) and attitude scores (OR = 1.20, 95% CI 1.08, 1.34) and higher monthly income. SEM showed knowledge directly affected attitude (β = 0.18) and practice (β = 0.46). CONCLUSIONS: Pregnant women showed relatively good knowledge and proactive practices, while attitudes were less favorable. Knowledge played a key role in shaping reported practices.
