Proinflammatory Diets during Pregnancy and Neonatal Adiposity in the Healthy Start Study.

ABSTRACT: OBJECTIVE:To evaluate the association between dietary inflammatory index (DII) scores during pregnancy and neonatal adiposity. STUDY DESIGN:The analysis included 1078 mother-neonate pairs in Healthy Start, a prospective prebirth cohort. Diet was assessed using repeated 24-hour dietary recalls. DII scores were obtained by summing nutrient intakes, which were standardized to global means and multiplied by inflammatory effect scores. Air displacement plethysmography measured fat mass and fat-free mass within 72 hours of birth. Linear and logistic models evaluated the associations of DII scores with birth weight, fat mass, fat-free mass, and percent fat mass, and with categorical outcomes of small- and large-for-gestational age. We tested for interactions with prepregnancy BMI and gestational weight gain. RESULTS:The interaction between prepregnancy BMI and DII was statistically significant for birth weight, neonatal fat mass, and neonatal percent fat mass. Among neonates born to obese women, each 1-unit increase in DII was associated with increased birth weight (53 g; 95% CI, 20, 87), fat mass (20 g; 95% CI, 7-33), and percent fat mass (0.5%; 95% CI, 0.2-0.8). No interaction was detected for small- and large-for-gestational age. Each 1-unit increase in DII score was associated a 40% increase in odds of a large-for-gestational age neonate (1.4; 95% CI, 1.0-2.0; P?=?.04), but not a small-for-gestational age neonate (1.0; 95% CI, 0.8-1.2; P?=?.80). There was no evidence of an interaction with gestational weight gain. CONCLUSIONS:Our findings support the hypothesis that an increased inflammatory milieu during pregnancy may be a risk factor for neonatal adiposity.

Project description:CONTEXT:The impact of specific maternal fuels and metabolic measures during early and late gestation on neonatal body composition is not well defined. OBJECTIVE:To determine how circulating maternal glucose, lipids, and insulin resistance in the first and second halves of pregnancy influence neonatal body composition. DESIGN:A prospective pre-birth cohort enrolling pregnant women, the Healthy Start Study, was conducted, in which fasting maternal serum samples were collected twice during pregnancy to measure glucose, insulin, hemoglobin A1c, triglyceride, total cholesterol, high-density lipoprotein, and free fatty acids. Neonatal body composition was measured with air displacement plethysmography. SETTING:An observational epidemiology study of pregnant women attending obstetric clinics at the University of Colorado, Anschutz Medical Center. PARTICIPANTS:This analysis includes 804 maternal-neonate pairs. RESULTS:A strong positive linear relationship between maternal estimated insulin resistance (homeostasis model of assessment for insulin resistance) in the first half of pregnancy and neonatal fat mass (FM) and FM percentage (FM%) was detected, independent of prepregnancy body mass index (BMI). In the second half of pregnancy, positive linear relationships between maternal glucose levels and offspring FM and FM% were observed, independent of prepregnancy BMI. An inverse relationship was detected between high-density lipoprotein in the first half of pregnancy and FM, independent of prepregnancy BMI. Free fatty acid levels in the second half of pregnancy were positively associated with higher birth weight, independent of prepregnancy BMI. CONCLUSION:Maternal insulin resistance in the first half of pregnancy is highly predictive of neonatal FM%, whereas maternal glycemia, even within the normal range, is an important driver of neonatal adiposity in later pregnancy, independent of prepregnancy BMI. Our data provide additional insights on potential maternal factors responsible for fetal fat accretion and early development of adiposity.

Project description:BackgroundMaternal obesity and weight gain during pregnancy are risk factors for child obesity. Associations may be attributable to causal effects of the intrauterine environment or genetic and postnatal environmental factors.ObjectiveWe estimated associations of maternal prepregnancy body mass index (BMI) and gestational weight gain (GWG) overall and in early pregnancy, midpregnancy, and late pregnancy with neonatal adiposity.DesignParticipants were 826 women enrolled in a Colorado prebirth cohort who delivered term infants (2010-2013). GWG to 39 wk of gestation was predicted by using mixed models, and early pregnancy, midpregnancy, and late pregnancy rates of GWG (0-17, 17-27, and 27 wk to delivery) were calculated from repeated weight measures. Neonatal body composition was measured by using air-displacement plethysmography ≤3 d after birth.ResultsEach1-kg/m(2) increase in maternal BMI was associated with increased neonatal fat mass (5.2 g; 95% CI: 3.5, 6.9 g), fat-free mass (7.7 g; 95% CI: 4.5, 10.9 g), and percentage of body fat (0.12%; 95% CI: 0.08%, 0.16%). Each 0.1-kg/wk increase in predicted GWG was associated with increased fat mass (24.0 g; 95% CI: 17.4, 30.5 g), fat-free mass (34.0 g; 95% CI: 21.4, 46.6 g), and percentage of body fat (0.55%; 95% CI: 0.37%, 0.72%). No interaction was detected between BMI and GWG in their effects on neonatal body composition. Early pregnancy, midpregnancy, and late pregnancy rates of GWG were independently associated with fat mass and percentage of body fat. Midpregnancy and late pregnancy GWGs were associated with fat-free mass. An observed GWG that exceeded recommendations was associated with higher neonatal fat mass and fat-free mass but not percentage of body fat relative to adequate GWG.ConclusionsMaternal prepregnancy BMI and GWG, including period-specific GWG, were positively and independently associated with neonatal adiposity. Associations of early and midpregnancy weight gain with neonatal adiposity support the hypothesis that greater maternal weight gain during pregnancy, regardless of prepregnancy BMI, is directly related to offspring adiposity at birth. The Healthy Start study was registered as an observational study at clinicaltrials.gov as NCT02273297.

Project description:Maternal obesity increases adult offspring risk for cardiovascular disease; however, the role of offspring adiposity in mediating this association remains poorly characterized.To investigate the associations of maternal pre-pregnant body mass index (maternal BMI) and gestational weight gain (GWG) with neonatal cardiometabolic markers independent of fetal growth and neonatal adiposity.A total of 753 maternal-infant pairs from the Healthy Start study, a large multiethnic pre-birth observational cohort were used. Neonatal cardiometabolic markers included cord blood glucose, insulin, glucose-to-insulin ratio (Glu/Ins), total and high-density lipoprotein cholesterol (HDL-c), triglycerides, free fatty acids and leptin. Maternal BMI was abstracted from medical records or self-reported. GWG was calculated as the difference between the first pre-pregnant weight and the last weight measurement before delivery. Neonatal adiposity (percent fat mass) was measured within 72?h of delivery using whole-body air-displacement plethysmography.In covariate adjusted models, maternal BMI was positively associated with cord blood insulin (P=0.01) and leptin (P<0.001) levels, and inversely associated with cord blood HDL-c (P=0.05) and Glu/Ins (P=0.003). Adjustment for fetal growth or neonatal adiposity attenuated the effect of maternal BMI on neonatal insulin, rendering the association nonsignificant. However, maternal BMI remained associated with higher leptin (P<0.0011), lower HDL-c (P=0.02) and Glu/Ins (P=0.05), independent of neonatal adiposity. GWG was positively associated with neonatal insulin (P=0.02), glucose (P=0.03) and leptin levels (P<0.001) and negatively associated with Glu/Ins (P=0.006). After adjusting for neonatal adiposity, GWG remained associated with higher neonatal glucose (P=0.02) and leptin levels (P=0.02) and lower Glu/Ins (P=0.048).Maternal weight prior and/or during pregnancy is associated with neonatal cardiometabolic makers including leptin, glucose and HDL-c at delivery, independent of neonatal adiposity. Our results suggest that intrauterine exposure to maternal obesity influences metabolic processes beyond fetal growth and fat accretion.

Project description:ObjectiveTo capture multidimensional maternal psychosocial stress using responses from the Edinburgh Postnatal Depression Scale (EPDS) and Cohen's Perceived Stress Scale (PSS) administered during pregnancy, and to identify sociodemographic, biological, and health behavioral correlates of the stress domains.MethodsUsing data from 1,079 pregnant women, we implemented principal component analysis on EPDS and PSS responses and retained factors based on the Scree plot and Eigenvalues >1. We then used linear regression to identify perinatal correlates of each domain.ResultsWe identified three stress domains: "Feeling Overwhelmed," "Anhedonia," and "Lack of Control," which accounted for 10.6% of variance in questionnaire responses. In multivariable analyses, household income ≤$70,000 (β = 0.21 confidence interval [95% CI: 0.05-0.39]), primiparity (0.36 [0.02-0.71]), inadequate (0.21 [0.04-0.39]) or excessive gestational weight gain (0.27 [0.11-0.42]), and Healthy Eating Index (HEI) score ≤57 (0.14 [0.00-0.28]) were associated with Feeling Overwhelmed. Older age (0.02 [0.00-0.03] per 1-year), Hispanic ethnicity (0.19 [0.00-0.38]), and HEI score ≤57 (0.15 [0.02-0.28]) were associated with Anhedonia. Non-Hispanic Black race/ethnicity (0.37 [0.10-0.63]), not having graduated from college (0.16 [-0.02 to 0.35]), having a partner born outside the United States (0.17 [-0.02 to 0.37]), household size of ≥5 persons (0.21 [-0.02 to 0.37]), receiving public assistance (0.18 [-0.02 to 0.37]), and prenatal smoking (0.32 [0.05-0.59]) were associated with Lack of Control.ConclusionsThree domains of maternal psychosocial stress during pregnancy (Feeling Overwhelmed, Anhedonia, and Lack of Control) were differentially related to sociodemographic, biological, and health behavioral characteristics that may be targets for interventions to ameliorate stress in pregnant women.Clinical trial registry: The Healthy Start study is registered as an observational study at clinicaltrials.gov (NCT #002273297).

Project description:BackgroundVegetarian diets are becoming increasingly popular in the USA. Limited research has examined the health consequences of vegetarian diets during pregnancy. We comprehensively examined associations of vegetarianism during pregnancy with maternal and neonatal outcomes.MethodsWe used data from the Eunice Kennedy Shriver National Institute of Child Health and Human Development's Fetal Growth Studies-Singletons, a prospective multi-site cohort of 1948 low-risk pregnant women of four races/ethnicities (White, Black, Hispanic, Asian/Pacific Islander) in the USA (2009-2013). Vegetarianism was self-reported and also defined based on dietary patterns measured using a self-administered first-trimester food-frequency questionnaire (full [lacto-ovo and vegan], pesco-, semi- and non-vegetarians). Neonatal outcomes included birthweight and neonatal anthropometric measures, small for gestational age, small for gestational age with neonatal morbidity and preterm delivery. Maternal outcomes included gestational weight gain, gestational diabetes, hypertensive disorders of pregnancy and gestational anaemia.ResultsNinety-nine (6.2%) women self-reported being vegetarian. The diet-based definition identified 32 (2.0%) full vegetarians, 7 (0.6%) pesco-vegetarians and 301 (17.6%) semi-vegetarians. Neonates of diet-based full vegetarians had higher odds of being small for gestational age [adjusted odds ratio (ORadj) = 2.51, 95% confidence interval: 1.01, 6.21], but not of being small for gestational age with a postnatal morbidity. Full vegetarians had marginally increased the odds of inadequate second-trimester gestational weight gain (ORadj = 2.24, 95% confidence interval: 0.95, 5.27).ConclusionVegetarian diets during pregnancy were associated with constitutionally smaller neonatal size, potentially via the mothers' reduced gestational weight gain. Notably, vegetarianism was not associated with small-for-gestational-age-related morbidities or other adverse maternal outcomes.

Project description:BACKGROUND:Infant body composition has been associated with later metabolic disease risk, but few studies have examined the association between maternal macronutrient intake and neonatal body composition. Furthermore, most of those studies have used proxy measures of body composition that may not reflect body fat distribution, particularly abdominal internal adiposity. OBJECTIVE:We investigated the relation between maternal macronutrient intake and neonatal abdominal adiposity measured by using MRI in a multiethnic Asian mother-offspring cohort. METHODS:The macronutrient intake of mothers was ascertained by using a 24-h dietary recall at 26-28 wk gestation. Neonatal abdominal adiposity was assessed by using MRI in week 2 of life. Mother-offspring dyads with complete macronutrient intake and adiposity information (n = 320) were included in the analysis. Associations were assessed by both substitution and addition models with the use of multivariable linear regressions. RESULTS:Mothers (mean age: 30 y) consumed (mean ± SD) 15.5% ± 4.3% of their energy from protein, 32.4% ± 7.7% from fat, and 52.1% ± 9.0% from carbohydrate. A higher-protein, lower-carbohydrate or -fat diet during pregnancy was associated with lower abdominal internal adipose tissue (IAT) in the neonates [? (95% CI): -0.18 mL (-0.35, -0.001 mL) per 1% protein-to-carbohydrate substitution and -0.25 mL (-0.46, -0.04 mL) per 1% protein-to-fat substitution]. These associations were stronger in boys than in girls (P-interaction < 0.05). Higher maternal intake of animal protein, but not plant protein, was associated with lower offspring IAT. In contrast, maternal macronutrient intake was not associated consistently with infant anthropometric measurements, including abdominal circumference and subscapular skinfold thickness. CONCLUSIONS:Higher maternal protein intake at the expense of carbohydrate or fat intake at 26-28 wk gestation was associated with lower abdominal internal adiposity in neonates. Optimizing maternal dietary balance might be a new approach to improve offspring body composition. This trial was registered at clinicaltrials.gov as NCT01174875.
