Fatigue and sleep quality in different trimesters of pregnancy

OBJECTIVES: Fatigue is one of the most common and persistent complaints of pregnant women. Increased severity of fatigue during pregnancy can increase the risk of preterm labor, prolonged labor, cesarean section, and postpartum depression. Therefore, this study aimed to determine the fatigue status in different trimesters of pregnancy and its relationship with sleep quality in pregnant women. MATERIAL AND METHODS: This cross-sectional study was performed by two-stage cluster sampling on pregnant women referred to Tabriz health centers. Data were collected using socio-demographic questionnaire, multidimensional assessment of fatigue and Pittsburgh sleep quality index. RESULTS: Among the 605 pregnant women studied, 94.2% of women suffered from fatigue during pregnancy. The mean (standard deviation) of fatigue score in the first, second and third trimesters of pregnancy was 23.53 (8.05), 25.78 (6.56) and 26.46 (6.72), respectively. There was also significant reverse correlation between total fatigue score with total sleep quality score (p=0.031) and with an increase in fatigue, sleep quality was reduced. DISCUSSION: The findings of this study may be used to design interventional measures for fatigue and medical care to improve quality of sleep in pregnancy.
