Trajectories of perinatal sleep quality from early pregnancy to six weeks postpartum and their risk factors: A multicenter longitudinal study in China

Key Points

• Postpartum sleep quality declines, particularly in women with high prenatal anxiety and stress levels.
• Sleep quality was assessed from early pregnancy through six weeks postpartum across multiple centers in China.
• The longitudinal study identifies various risk factors impacting sleep across the perinatal period, including lifestyle and psychological stress.
• Understanding these trajectories supports the need for interventions to improve mental health and sleep quality after childbirth.
