Effects of Advanced Maternal Age and Race/Ethnicity on Placental Weight and Placental Weight/Birthweight Ratio in Very Low Birthweight Infants

To study the association of advanced maternal age (AMA) and race/ethnicity on placental pathology in very low birthweight (VLBW) infants. Retrospective analysis of placental pathology of inborn singleton VLBW infants from a regional level 3 NICU between July, 2002 and June, 2009. Subjects were strat...

Description
Summary:To study the association of advanced maternal age (AMA) and race/ethnicity on placental pathology in very low birthweight (VLBW) infants. Retrospective analysis of placental pathology of inborn singleton VLBW infants from a regional level 3 NICU between July, 2002 and June, 2009. Subjects were stratified by age and race/ethnicity. Statistical analysis included One-way ANOVA, Chi Square and multivariable analyses. A total of 739 mother/infant dyads were included. AMA was associated with a decrease in placental weight and placental weight/birthweight ratio. Black/Non-Hispanic mothers ≥35 had a lower placental weight ( p  = 0.01) and lower placental weight/birth weight ratio (z-score, −0.45 ± 0.71 vs −0.04 ± 1.1, p  = 0.01) compared to Black/Non-Hispanic mothers
