ASSESSMENT OF SOME EFFECTIVE FACTORS ON THE WEIGHT GAIN DURING PREGNANCY AND BIRTH WEIGHT OF NEWBORNS

Background and Objectives: The nutritional status of women prior to pregnancy as well as during gestational period influences maternal and fetal well - being. The objectives of this study were : assessment of weight gain during pregnancy, birth weight status and some effective factors in women who attended health centers of Maraud district, Tabriz. Materials and Methods: A total of 91 pregnant women were studied in this longitudinal, descriptive -analytical survey by interviewing with subjects and athropometric measurments. Results: Mean pregnancy weight gain was 8.12± 2.99 kg and mean birth weight of the newborns was 3350 ± 46mg. From all subjects only 12% had prepregnancy BMI lower than 19.8 and 73.63% of subjects had inadequate weight gain during pregnancy. Negative significant correlation was found between pregnancy weight gain and age of mothers (r =-().31, p<0.002). Birth weight of newborns correlated positively and significantly with prepregnancy weight and prepregnancy BMI of mothers and sex (male) of new borns(r=0.39, p<0.000l, r=0.35, p<0.00l, r=0.23, p<0.03, respectively). Based on stepwise multiple regression analysis, prepregnancy weight of mothers was the most independent variable associated with the birth weight. Conclusion: These findings indicate the importance of the effect of prepregnancy maternal weight on the newborn weight status. Therefore, nutritional interventions are emphasized to improve the nutritional status of women prior to pregnancy as well as during pregnancy.
