Characteristics of Recurrent Large-for-Gestational-Age Infants in Obese Women.

Objective The objective of this study was to identify characteristics associated with recurrent large-for-gestational-age (LGA) infants in obese women and to explore the relationship between interpregnancy weight change and gestational weight gain (GWG) on risk of recurrence. Study Design We conducted a population-based historical cohort study of 1,190 obese women in Missouri who delivered LGA infants in their first pregnancy with two consecutive pregnancies resulting in singleton live births during 1998 to 2005. Adjusted odds ratios (aORs) for recurrent LGA infants were calculated with multiple logistic regression.

The impact of interpregnancy weight change on birthweight in obese women.

Objective: The purpose of this study was to estimate the impact of interpregnancy weight change from first to second pregnancies in obese women on the risk of large-for-gestational-age (LGA) and small-for-gestational-age (SGA) infants.

Study Design: A population-based historical cohort analysis of 10,444 obese women in Missouri who delivered their first 2 singleton live infants from 1998-2005. Interpregnancy weight change was calculated as the difference between prepregnancy body mass index (BMI) of the first and second pregnancies.
