Abstract

 Background and Objectives

 Studies on the relationship between maternal hemoglobin (Hb) level and adverse pregnancy outcomes have been inconsistent. The aim of this study was to examine the birth outcomes in pregnant adolescents as high risk mothers.

 Materials and Methods

 In this cross sectional study, 312 healthy pregnant women with GA=37-40 weeks were selected by random sampling. After their medical records were taken and clinical investigation done, Hb tests were conducted. After birth, the correlation between the levels of Hb concentration during pregnancy and birth outcomes was estimated. Statistical analyses were performed with SPSS software using t-test, chi-square, and ANOVA.

 Results

 The prevalence rate of anemia was 23.2 % . The average birth weight was 3197.8 ± 398.25 g and it was higher in mothers with Hb=10.5-12.5 g/dL than others (10.5 > Hb > 12.5 g/dL) (p< 0.01). Apgar score less than 8 was higher in the anemic group.

 Conclusions

 Our findings demonstrated that abnormal Hb concentrations increased the risk of adverse birth outcomes in pregnant adolescents. Thus, the intensive care is recommended for them.
