Do Early Adolescent and Advanced Maternal Age Pregnancies Affect Term Birthweight?

Although it is known that there is a relationship between birthweight and maternal age, adverse pregnancy outcomes are reportedmore frequently in adolescent pregnancies (AP) and advanced maternal age pregnancies (AMA). We aimed to compare the meanmaternal age at delivery for the last 5 years in our hospital. And also we evaluated birthweights and adverse pregnancy outcomes infull-term births for maternal age categories.We evaluated 63,432 singleton birth between 2013 and 2018. In a subgroup, 21.575 full-term births were analyzed according to thebirthweight, type of delivery, maternal age category (including early AP and AMA), and over the years. In the statistical comparisons,ANOVA-test was performed for continuous data and Tukey-test was performed as an advanced analysis. The relationship betweenmaternal age and birth weight in the subgroup was analyzed by Pearson Correlation, and chi-square test was used for categoricalvalues. A P<.05 value was taken as significant.The mean maternal age was 26 years and no significant change was found according to years. Stillbirth rates were determined assignificantly higher in AMA (2.6%; p <0.001). In the early AP, the rate of low birthweight infants was highest (16%). The meanbirthweight was found to be the highest in the AMA directly proportional to the maternal age (r = 0.13, p
