A study led by the University of Granada, in which the Andalusian Health Service (SAS) and researchers from the University of Jaen have taken part, reveals that 64% of pregnant women suffer from insomnia in the third trimester of pregnancy. This figure is ten times higher than that for women suffering from insomnia prior to pregnancy (6%). The research study was recently published in the prestigious European Journal of Obstetrics & Gynecology and Reproductive Biology. 486 healthy pregnant women from Granada, Jaen, Huelva and Seville who had attended the Andalusian Health Service (SAS) before the 14th week of pregnancy (first trimester) participated in the study. The effects of pregnancy on these women were monitored throughout all three trimesters. The results reveal that 44% of pregnant women suffer from insomnia in the first trimester of pregnancy, which increases to 46% in the second trimester and 64% in the third trimester. These are very high figures which, according to the authors of the research, justify the need for a “systematic approach to this problem.”
