ABSTRACT
Investigations have shown that the emotional stress during the pregnancy period could have sustainable effects on the embryo. Different factors such as family members, spouse, supporting friends could relive these effects, but coping skills especially relaxation could be more effective on stress. This study was conducted to investigate the effect of relaxation training to pregnant mothers on health index such as Apgar index, weight, height, and cowlick grade in infants. This is a clinical trail in which 100 pregnant women who referred to health center of Yasuj [2006-2008] were selected using simple sampling method and assigned randomly to case and control groups. The relaxation was taught to the case group whereas nothing was taught to control groups. At the time of delivery the above mentioned indices were assessed. The gathered data was analyzed using SPSS software. The results showed a significant difference between two groups in weight, height, cephalic index, and colic grade [with better situation in case group]. There was no significant difference between two groups in Apgar scores. Considering the results of this study, it seems that teaching of relaxation to pregnant women could be effective in health index of children especially in the time of delivery. Therefore attention should be paid to different methods for reducing the stress in this group of mothers
