RESUMO
This is an interventional research. Its objective was to survey the effect of educational intervention on improvement of nutritional behaviours in pregnant women referring to kermanshah health care centers in 1384. This study was conducted on 180 pregnant women selected randomly [90 in intervention group and 90 in control group] and their gestational health services were provided in 9 urban health centers. Their nutritional knowledge, attitude and practice were assessed before implementation of educational program by using questionnaire. These variables were evaluated and analized one month after implementation of the program in intervention group. The results indicated no significant difference between control and intervention groups regarding the variables. Also the mean score of knowledge attitude and practice in control and intervention groups before education showed no significant difference. However the relationship between knowledge attitude and practice in the two groups before and after education was statistically significant. The mean of knowledge, attitude and practice scores increased significantly after education in intervention group [P<0/0001]. Regarding these results, positive effects of gestational nutrition education for pregnant women can be regarded as important. So we recommend a nutritional education program for pregnant women in the health care system
