Abstract
This study used data from the Sao Paulo Epidemiologic Sleep Study (EPISONO) undertaken in 2007, with a follow-up study in 2015. Women who took part in both editions of the study were distributed in two groups: those with insomnia symptoms (GIS) and those without insomnia symptoms (GWIS). To evaluate groups over time, the Chalder Fatigue Questionnaire, the Beck Anxiety Inventory, the Beck Depression Index, and the World Health Organization Quality of Life assessment were used. Additionally, full-night polysomnography was used to assess the participants’ sleep pattern. The GWIS presented significantly less fatigue, anxiety, and depression, and better results in all domains of quality of life, in both EPISONO editions. Moreover, time had a significant impact on the levels of fatigue and depression, regardless of groups. Insomnia symptoms were associated with higher levels of fatigue, anxiety and depression and a lower perception of quality of life, regardless of time.
