Objective The objective of this study was to determine the effect, if any, of maternal body mass index (BMI) and amniotic fluid index (AFI) on the accuracy of sonographic estimated fetal weight (EFW) at 40 to 42 weeks' gestation. Methods This was a retrospective cohort study of singleton gestations with ultrasound performed at 40 to 42 weeks from 2010 to 2013. In this study, patients with documented BMI and sonographic EFW and AFI, concurrently, within 7 days of delivery were included. Chronic medical conditions and fetal anomalies were excluded from this study. The primary variable of interest was the rate of substantial error in EFW, defined as absolute percentage error (APE) >10%. Results A total of 1,000 pregnancies were included. Overall, the APE was 6.0 ± 4.5% and the rate of substantial error was 17.4% (n = 174). There was no significant difference in APE or rate of substantial error between BMI groups. In the final multivariable logistic regression model, the rate of substantial error was increased in women with oligohydramnios (OR 1.79; 95% CI: 1.10–2.92). Furthermore, oligohydramnios was significantly more likely to overestimate EFW while polyhydramnios was more likely to underestimate EFW. Maternal BMI did not affect the accuracy of sonographic EFW. Conclusion Sonographic EFW may be affected by extremes of AFI in the postdates period. Maternal BMI does not affect EFW accuracy at 40 to 42 weeks.

Maternal body mass index (BMI) has been reported to be associated with the number of fetal body movements and the duration of fetal breathing movements in hypertensive pregnant women (Brown et al., 2008). However, whether a relationship exists in pregnancies classified as overweight or normal weight but not complicated by hypertension is unknown and the focus of this study. Forty-five maternal-fetal pairs (normotensive, normal weight=15; normotensive, overweight=15; hypertensive=15) who had participated in a study of fetal behavior which included a 20 min real-time ultrasound scan observation of fetal movements were randomly selected from the laboratory archival database. Gestational age at testing ranged from 33-39 weeks [M(SD)= 36.2 (1.4) weeks]. All infants were delivered healthy at term. Video-recordings of the ultrasound scans were scored for the number of fetal body movements (interrater reliability r=.97) and the cumulative duration of breathing (interrater reliability r=.94) movements. The number of fetal body movements differed between groups, F(2,38)=3.19, p=0.05, with fetuses of overweight mothers moving less frequently than those of normal weight mothers (M=9.7 vs 15.5, respectively). Maternal BMI prior to pregnancy, r=-0.43, p<0.01, and at time of observation, r=-0.44, p<0.01, was associated with the number of fetal body movements, but not with duration of breathing movements. As BMI increased, the number of fetal body movements decreased. It was concluded that maternal BMI may affect the number of spontaneous fetal movements. A prospective study is necessary to determine whether BMI should be considered when using body movement counts to assess well-being and/or neurodevelopment.

AbstractMaternal obesity in pregnancy predicts offspring psychopathology risk in childhood but it remains unclear whether maternal obesity or underweight associate with adult offspring mental disorders. We examined longitudinally whether maternal body mass index (BMI) in pregnancy predicted mental disorders in her offspring and whether the associations differed by offspring birth year among 68,571 mother–child dyads of Aberdeen Maternity and Neonatal Databank, Scotland. The offspring were born 1950–1999. Maternal BMI was measured at a mean 15.7 gestational weeks and classified into underweight, normal weight, overweight, moderate obesity and severe obesity. Mental disorders were identified from nationwide registers carrying diagnoses of all hospitalizations and deaths in Scotland in 1996–2017. We found that maternal BMI in pregnancy was associated with offspring mental disorders in a time-dependent manner: In offspring born 1950–1974, maternal underweight predicted an increased hazard of mental disorders [Hazard Ratio (HR) = 1.74; 95% Confidence Interval (CI) = 1.01–3.00)]. In offspring born 1975–1999, maternal severe obesity predicted increased hazards of any mental (HR 1.60; 95% CI 1.08–2.38) substance use (HR 1.91; 95% CI 1.03–3.57) and schizophrenia spectrum (HR 2.80; 95% CI 1.40–5.63) disorders. Our findings of time-specific associations between maternal prenatal BMI and adult offspring mental disorders may carry important public health implications by underlining possible lifelong effects of maternal BMI on offspring psychopathology.
