P-215: Study of Some Related Factors with Fetal Macrosomia and Low Birth Weight

Background: Birth weight are the major factors determining the physical and mental development of infants and credible signs of intrauterine growth. The purpose of this study was the Study of birth weight on maternal and neonatal factors in the women referred to delivery room of Specialized Hospital in 2010. Materials and Methods: In this cross sectional study, 3076 women with the normal vaginal delivery (NVD) entered into the study population. The Statistical Package for the Social Sciences, SPSS 17 for Windows, was used for the analysis. Data analysis was performed by using descriptive and analytical statistics (mean ± SD), Chi-square test, independent sample t test, ANOVA, post hoc scheffe and liner regression). The significant level was set at less than 0.05 (p<0.05). Results: The prevalence rate of low birth weight was 6.7% (205) and macrosomia 3.2% (97). Average neonatal birth weight was 3248.18 ± 458 g and maternal age was 25.33 ± 5.7 years. On the basis of linear regression, types and number of delivery, neonatal sex, preeclampia and age of mother were respectively the most factors of low birth weight. None of them relate to macrosomia. Conclusion: Our findings showed by detection and control of many factors which relate to birth weight, we can decrease prevalence of low birth weight and macrosomia and result in normal birth weight.
