RESUMEN
Fatigue is one of the pregnant women prevalent complaints during pregnancy. Physical, psychological and situational factors predispose the women to fatigue. The aim of this study was to determine the correlation between intensity of fatigue and pregnancy outcome. In this analytical-descriptive study, a total of 180 pregnant mothers who had characteristics of survey units were selected by multistage sampling. They completed questionnaire from 32 week of gestation up to labor pain. Then, they were divided into 3 groups of mild, moderate and severe base on their fatigue scores. Age and birth weight determined with questionnaire and checklist and correlation between intensity of fatigue and delivery type, age and weight in birth with statistical tests were calculated. Based on the results, the frequency of mild, intermediate and intensive fatigue in the women were 37.77%, 35%, and 27.22%, respectively. The intensity of fatigue was correlated with delivery type [P<0.05, OR=1.07], neonatal age at birth [P<0.001, r=0.470] and birth weight [P<0.001, r=0.911]. Fatigue in pregnant women is a main problem and has undesirable effects on its outcome. Therefore, attention to train and interventional care for reduction of fatigue is suggested
