“…[6][7][8][9] Recent studies have linked some of these same exposures with early postnatal growth. For instance, smoking during pregnancy has been linked both directly with rapid growth and indirectly to rapid growth by low birth weight.…”

Association between Prepregnancy Body Mass Index and Gestational Weight Gain with Size, Tempo, and Velocity of Infant Growth: Analysis of the Newborn Epigenetic Study Cohort

Background: The first 1000 days of life is a critical period of infant growth that has been linked to future adult health. Understanding prenatal factors that contribute to variation in growth during this period could inform successful prevention strategies.Methods: Prenatal and maternal characteristics, including prepregnancy obesity and gestational weight gain were evaluated in relation to weight growth trajectories during the first 24 months of life using the SuperImposition by Translation and Rotation (SITAR) method, which provides estimates of infant size, timing to peak velocity, and growth velocity. The study sample included 704 mother-infant dyads from a multiethnic prebirth cohort from the Southeastern United States. The total number of weight measures was 8670 (median number per child = 14).Results: Several prenatal and maternal characteristics were linked with infant growth parameters. The primary findings show that compared to women with a prepregnancy BMI between 18 and 24.9, women with a prepregnancy BMI ‡40 had infants that were 8% larger during the first 24 months, a delayed tempo of around 9 days, and a slower velocity. Mothers who had greater than adequate gestational weight gain had infants that were 5% larger even after controlling for prepregnancy BMI and several other covariates.Conclusions: The findings contribute new data on the associations between gestational weight gain and aspects of early growth using the SITAR method, and support a growing consensus in the literature that both prepregnancy BMI and gestational weight gain relate independently to risk for greater postnatal weight growth.

“…Recent evidence showed inadequate weight gain during pregnancy (both low and excessive) was linked to preterm birth at various BMI starting points. 12,13 Women who do not gain weight within the guidelines set by the Institute of Medicine (IOM) 14 are more likely to have suboptimal outcomes than women who gain the recommended amount of weight for their BMI. 15 We investigated maternal weight in relation to core symptoms of ADHD in offspring using prospective data gathered within three Nordic pregnancy cohorts considering also the combination of pre-pregnancy BMI and pregnancy weight gain.…”

Maternal adiposity prior to pregnancy is associated with ADHD symptoms in offspring: evidence from three prospective pregnancy cohorts

et al. 2007

Objectives: We examine whether pregnancy weight (pre-pregnancy body mass index (BMI) and/or weight gain) is related to core symptoms of attention deficit hyperactivity disorder (ADHD) in school-age offspring. Design: Follow-up of prospective pregnancy cohorts from Sweden, Denmark and Finland within the Nordic Network on ADHD. Methods: Maternal pregnancy and delivery data were collected prospectively. Teachers rated inattention and hyperactivity symptoms in offspring. High scores were defined as at least one core symptom rated as 'severe' and two as 'present' (approximately 10% of children scored in this range). Logistic regression and latent class analyses were used to examine maternal pregnancy weight in relation to children's ADHD core symptoms. Results: Teacher rated 12 556 school-aged children. Gestational weight gain outside of the Institute of Medicine guidelines was not related to ADHD symptoms (below recommendations: odds ratio (OR): 0.96; 95% confidence interval (CI): 0.81, 1.14; above recommendations: OR: 0.98; 95% CI: 0.82, 1.16). To examine various patterns of pre-pregnancy BMI and weight gain, we used latent class analysis and found significant associations between classes that included pre-pregnancy overweight or obesity and a high ADHD symptom score in offspring, ORs ranged between 1.37 (95% CI: 1.07, 1.75) and 1.89 (95% CI: 1.13, 3.15) adjusted for gestational age, birth weight, weight gain, pregnancy smoking, maternal age, maternal education, child gender, family structure and cohort country of origin. Children of women who were both overweight and gained a large amount of weight during gestation had a 2-fold risk of ADHD symptoms (OR: 2.10, 95% CI: 1.19, 3.72) compared to normal-weight women. Conclusions: We show for the first time that pre-pregnancy BMI is associated with ADHD symptoms in children. Our results are of public health significance if the associations are causal and will then add ADHD symptoms in offspring to the list of deleterious outcomes related to overweight and obesity in the prenatal period.

“…There seems to be an upward trend [2,3], which contributes to almost 3.6 million preterm births accounting for 23.6% of the global preterm births reported each year [4]. Preterm birth has been consistently associated with maternal underweight and nutrient deficiencies during pregnancy [5][6][7][8][9]. Therefore, nutritional assessment needs to be an integral part of antenatal care and should be continued during pregnancy in order to reduce the risk of maternal, fetal and neonatal complications, as well as the short-and long-term adverse outcomes.…”

Energy and protein intake during pregnancy in relation to preterm birth: A Case Control Study

et al. 2015

View full text Add to dashboard Cite

Objective: To find the association of maternal energy and protein intake with preterm birth.Design: Case-control study. Setting:Two hospitals at Lucknow in Northern India.Participants: Cases (n=350) were defined as mothers (age 18-40 y) of singleton live preterm (<37 wks) neonates. Controls (n=350) were mothers who delivered a singleton neonate, consecutive to enrolled case, after completing 37 weeks of gestation.Results: There was a statistically significant lower mean (SD) energy intake [cases 1624 (249) Conclusion:Lower energy and protein intake during pregnancy is possibly associated with preterm birth.

Combined Effects of Prepregnancy Body Mass Index and Weight Gain During Pregnancy on the Risk of Preterm Delivery

Abstract: This study supports concerns about very low weight gain during pregnancy, even among overweight and obese women, and also suggests that high weight gain, regardless of prepregnancy BMI, deserves further investigation.
