Insomnia During the Perinatal Period and its Association with Maternal and Infant Psychopathology: A Systematic Review and Meta-Analysis.

While sleep serves important regulatory functions for mental health, sleep disturbances, in particular insomnia, may contribute to mental disorders. Since insomnia symptoms are frequent during the perinatal period, the aim of this work is to systematically review the potential association between perinatal insomnia and maternal and infant psychopathology. A systematic search was conducted according with PRISMA guidelines, and meta-analytic calculations were conducted. Totally, 34 studies were included and involved 835,021 perinatal women. Four meta-analysis yielded four statistically significant random-effect models. All models show that women with perinatal symptoms of insomnia possess increased odds of developing clinically relevant symptoms of depression OR = 3.69, p = 0.001 and anxiety OR = 2.81; p < 0.001, as well as increased suicidal risk OR = 3.28; p < 0.001, and distress in the newborn OR = 2.80 (P = 0.007). These findings emphasize the role of assessing and addressing insomnia during the perinatal period to mitigate its negative effect on maternal and infant mental health via sleep regulation.
