[PMID: 38614240 PMCID: PMC11217026 DOI: 10.1016/j.tjnut.2024.04.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2023] [Revised: 03/11/2024] [Accepted: 04/09/2024] [Indexed: 04/15/2024] Open
Abstract
BACKGROUND Few diet quality indices have been developed and validated for use among children and adolescents. Additionally, many available indices require completion of burdensome dietary assessments. OBJECTIVES We aimed to calculate and evaluate the performance of a modified version of the food-based Prime Diet Quality Score (PDQS) derived from different diet assessment methods conducted at 4 time points in a single study population from childhood through adolescence. METHODS Among 1460 child participants in the Project Viva cohort, we calculated the PDQS in early and mid-childhood and early and mid-adolescence using dietary data obtained from food frequency questionnaire (early childhood: parent report), PrimeScreen (mid-childhood: parent report; early adolescence: self-report) and 24-h recall (mid-adolescence: self-report). We evaluated construct and relative validity and internal reliability of the score in each life stage. RESULTS The PDQS showed a range of scores at all life stages and higher scores were associated with intake of many health-promoting macronutrients and micronutrients (e.g., protein, fiber, and vitamins) in early childhood and mid-adolescence. The PDQS performed similarly to the Youth Healthy Eating Index/Healthy Eating Index (Spearman r = 0.63-0.85) in various assessments. Higher PDQS was associated with expected characteristics including more frequent breakfast eating, family dinners, and vigorous physical activity; with less frequent TV viewing and fast food intake; and with more sleep and higher maternal diet scores during pregnancy. Cross-sectional associations of the PDQS with various anthropometric measurements and biomarkers were inconsistent but generally in the expected directions (e.g., higher PDQS associated with lower triglycerides and insulin and higher HDL cholesterol). Internal reliability was consistent with what has been found for other diet quality indices. CONCLUSIONS The PDQS can be calculated from data collected using different and brief dietary assessment methods and appears to be a valid and useful measure of overall diet quality in children and adolescents. Project Viva was registered at clinicaltrials.gov as NCT02820402.

Mediators of the association between maternal body mass index and breastfeeding duration in 3 international cohorts. Am J Clin Nutr 2023; 118:255-263. [PMID: 37407164 PMCID: PMC10493413 DOI: 10.1016/j.ajcnut.2023.04.004] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2022] [Revised: 03/07/2023] [Accepted: 04/03/2023] [Indexed: 07/07/2023] Open
Abstract
BACKGROUND Maternal obesity has been associated with shorter breastfeeding duration, but little is known about mediating factors explaining this association. It is important to assess these relationships across diverse populations because breastfeeding is culturally patterned. OBJECTIVES We investigated the association of prepregnancy maternal body mass index (BMI) with breastfeeding outcomes and potential mediators of this relationship in 3 culturally diverse international cohorts. METHODS We analyzed 5120 singleton pregnancies from mother-child cohorts in Spain (INfancia y Medio Ambiente), Greece (Rhea), and the United States (Project Viva). Outcome variables were duration of any and exclusive breastfeeding. A priori hypothesized mediators in the association of maternal prepregnancy BMI with breastfeeding were birthweight (BW), maternal prenatal C-reactive protein (CRP), cesarean delivery, maternal dietary inflammatory index (DII) during pregnancy, gestational age at delivery, and gestational diabetes mellitus (GDM). We estimated the association between BMI and breastfeeding duration using linear regression adjusting for confounders. Mediation analysis estimated direct and indirect effects of maternal overweight/obesity on breastfeeding for each mediator. RESULTS Women with overweight and obesity had shorter duration of any and exclusive breastfeeding compared with normal-weight women (any: overweight β = -0.79 mo, 95% CI: -1.17, -0.40; obese β = -1.75 mo 95% CI: -2.25, -1.25; exclusive: overweight β = -0.30 mo, 95% CI: -0.42, -0.16; obese β = -0.73 mo, 95% CI: -0.90, -0.55). Significant mediators (% change in effect estimate) of this association were higher CRP (exclusive: 5.12%), cesarean delivery (any: 6.54%; exclusive: 7.69%), and higher DII (any: 6.48%; exclusive: 7.69%). GDM, gestational age, and BW did not mediate the association of maternal weight status with breastfeeding. CONCLUSIONS Higher prepregnancy BMI is associated with shorter duration of any and exclusive breastfeeding. Maternal dietary inflammation, systemic inflammation, and mode of delivery may be key modifiable mediators of this association. Identification of mediators provides potential targets for interventions to improve breastfeeding outcomes.

THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY. IN PRACTICE 2022; 10:2713-2721.e2. [PMID: 35779778 PMCID: PMC10846592 DOI: 10.1016/j.jaip.2022.06.022] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/16/2022] [Revised: 05/09/2022] [Accepted: 06/14/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Current guidelines emphasize early introduction to potentially allergenic foods, but the optimal timing, amount, and exposure routes for foods other than peanut are not well-established. Cow's milk is often the first allergenic food introduced through infant formulas. OBJECTIVE To examine timing of cow's milk protein introduction (CMPI), including interaction with formula supplementation after delivery, in relation to reported cow's milk adverse reactions throughout childhood. METHODS Among children in the Boston, Mass-area Project Viva cohort, we assessed timing of CMPI (<2 weeks, 2 weeks-<6 months, ≥6 months) with questionnaires administered in infancy. Outcomes were (1) parent-reported cow's milk adverse reactions via annual questionnaires from age 2 to 13 years (n = 1298) and (2) milk sensitization (n = 505) and IgE-mediated milk allergy (n = 491) at age approximately 8 years. We used multivariable logistic regression models adjusted for parental atopy history, delivery mode, gestational age at delivery, child race, and census tract median household income, and investigated effect modification by ever/never breast-fed status and formula supplementation in the delivery hospital. RESULTS A total of 32% were introduced to cow's milk protein at age less than 2 weeks, 38% at age 2 weeks to less than 6 months, and 30% at age 6 months or more. Compared with children with CMPI at age less than 2 weeks, children with CMPI at age 6 months or more had a higher risk of cow's milk adverse reaction at age 2 to 5 years (odds ratio, 2.4 [1.2-4.7]). Children given formula after delivery + CMPI at age less than 2 weeks had the lowest risk overall. Among children not given formula after delivery, CMPI at age 2 weeks to 6 months appeared most protective. Results were similar among ever-breast-fed children. Timing of CMPI was not associated with milk sensitization or IgE-mediated milk allergy in mid-childhood. CONCLUSIONS Early, consistent cow's milk exposure appears protective against adverse reactions to cow's milk.

J Nutr 2021; 151:1256-1268. [PMID: 33693813 PMCID: PMC8243768 DOI: 10.1093/jn/nxaa456] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2020] [Revised: 12/08/2020] [Accepted: 12/29/2020] [Indexed: 01/17/2023] Open
Abstract
BACKGROUND Suboptimal vitamin D (VitD) status has been associated with poor bone health and other adverse health outcomes and is common among children. Various early-life factors are associated with child VitD, yet few studies have examined multiple factors simultaneously in a single study population. OBJECTIVES We aimed to characterize relations of early-life factors with plasma 25-hydroxyvitamin D [25(OH)D] concentrations in early and mid-childhood, and to explore potential differences in these associations between white and black children. METHODS We identified associations of various early-life factors with 25(OH)D concentrations in early and mid-childhood among 961 children in Project Viva using linear regression models. All variables associated with 25(OH)D were included together in final multivariable models at each outcome time point: 1 in the overall sample and additional models for children whose mothers identified them as being white or black. RESULTS Overall mean ± SD 25(OH)D concentrations were 86 ± 29 nmol/L in early childhood and 68 ± 21 nmol/L in mid-childhood. After accounting for other predictors, children who took VitD supplements (compared with those who did not) had 25(OH)D concentrations 5.6 nmol/L (95% CI: 2.0, 9.2 nmol/L) higher in early childhood and 8.2 nmol/L (95% CI: 4.8, 11.6 nmol/L) higher in mid-childhood. Other factors consistently associated with higher 25(OH)D were blood collection in summer or fall, white race, nonfall birth season, prenatal exposure to higher 25(OH)D, and higher dietary intake of VitD. Greater waist circumference was associated with lower 25(OH)D in early childhood (β: -3.8; 95% CI: -7.4, -0.2 per 1-SD increase) among black children only. CONCLUSIONS Our findings may help clinicians better target children at risk of lower 25(OH)D for screening and/or intervention and may inform research focused on associations of 25(OH)D with different exposures and outcomes or causal effects of early-life factors on later VitD status.This trial was registered at clinicaltrials.gov as NCT02820402.

Abstract
OBJECTIVE To evaluate the associations of pregestational BMI, gestational weight gain (GWG) and breast-feeding at 1 month postpartum with four patterns of weight change during the first year after delivery: postpartum weight retention (PPWR), postpartum weight gain (PPWG), postpartum weight retention + gain (PPWR + WG) and return to pregestational weight. DESIGN In this secondary analysis of a prospective study, we categorised postpartum weight change into four patterns using pregestational weight and weights at 1, 6 and 12 months postpartum. We evaluated their associations with pregestational BMI, GWG and breast-feeding using multinomial logistic regression. Results are presented as relative risk ratios (RRR) and 95 % CI. SETTING Mexico City. PARTICIPANTS Women participating in the Programming Research in Obesity, Growth, Environment and Social Stressors pregnancy cohort. RESULTS Five hundred women were included (53 % of the cohort). Most women returned to their pregestational weight by 1 year postpartum (57 %); 8 % experienced PPWR, 14 % PPWG and 21 % PPWR + WG. Compared with normal weight, pregestational overweight (RRR 2·5, 95 % CI 1·3, 4·8) and obesity (RRR 2·2, 95 % CI 1·0, 4·7) were associated with a higher risk of PPWG. Exclusive breast-feeding, compared with no breast-feeding, was associated with a lower risk of PPWR (RRR 0·3, 95 % CI 0·1, 0·9). Excessive GWG, compared with adequate, was associated with a higher risk of PPWR (RRR 3·3, 95 % CI 1·6, 6·9) and PPWR + WG (RRR 2·4, 95 % CI 1·4, 4·2). CONCLUSIONS Targeting women with pregestational overweight or obesity and excessive GWG, as well as promoting breast-feeding, may impact the pattern of weight change after delivery and long-term women's health.

Abstract
OBJECTIVE The purpose of this study was to test the extent to which pregnancy per- and polyfluoroalkyl substance (PFAS) concentrations were associated with gestational weight gain and postpartum weight changes. METHODS This study was composed of 1,614 women recruited between 1999 and 2002 via the Project Viva cohort with pregnancy plasma concentrations of six PFAS, including perfluorooctanesulfonic acid, perfluorooctanoic acid (PFOA), and 2-(N-ethyl-perfluorooctane sulfonamido) acetic acid. Gestational weight gain was defined as the difference between last pregnancy weight and prepregnancy weight, 1-year postpartum weight retention as the difference between 1-year postpartum weight and prepregnancy weight, and 3-year postpartum weight change as the difference between 3-year postpartum weight and prepregnancy weight. RESULTS During pregnancy, women gained 0.37 kg (95% CI: 0.11-0.62) more weight per doubling of 2-(N-ethyl-perfluorooctane sulfonamido) acetic acid. At 1 year post partum, women retained 0.55 kg (95% CI: 0.07-1.04) more weight per doubling of PFOA. At 3 years post partum, women gained 0.91 kg (95% CI: 0.25-1.56) more weight per doubling in PFOA. Findings were similar after adjustment for all PFAS. Other PFAS were not associated with weight changes. Postpartum associations were stronger among women with higher prepregnancy BMI. Models were adjusted for demographics. CONCLUSIONS Pregnancy PFAS were associated with greater gestational weight gain, weight retention, and weight gain years after pregnancy.

Abstract
Latinos are the largest and fastest-growing minority group in the U.S., and Latina women represent the largest portion of minority births, having the highest birth rate in the U.S. for over 20 years. In addition, Latina women are at increased risk of entering pregnancy being overweight or having obesity and gaining excess gestational weight. Excess gestational weight gain (GWG) has short- and long-term adverse health outcomes for the woman and her child. Although culturally tailored interventions show promise toward promoting healthy GWG among Latina women, findings from current interventions have had mixed results, suggesting the need for further tailoring to meet the needs of this heterogeneous population group. This qualitative study was designed to explore first-time pregnant, low-income Latina women’s beliefs, attitudes, and experiences with GWG. The study employed qualitative research using semi-structured interviews conducted with 23 first-time pregnant Latina women between 22 and 36 weeks of gestation. Interviews were conducted by trained bilingual staff, transcribed verbatim, and analyzed using thematic analysis. Results showed that participants were uncertain if their GWG was within a healthy range. Although the majority of participants knew that GWG should be limited, they were not sure what the amount should be. In addition, the majority of participants reported attitudes of acceptance of and resignation to excessive GWG as being part of pregnancy. Several women appeared to believe that they did not have control over their weight gain during pregnancy. Moreover, analysis identified that sociocultural and interpersonal factors such as social support influence the beliefs, attitudes, and experiences with GWG of the low-income, majority immigrant Latina women who participated in this study. Study findings can be used to further tailor prenatal care practices and interventions aimed at altering modifiable risk factors associated with excess GWG among Latinas. Future interventions designed for low-income, immigrant Latina women that consider sociocultural influences on women’s beliefs and attitudes related to GWG, as well as the influence of social support networks on women’s health behaviors during pregnancy, will likely be more effective in preventing excessive GWG.

Abstract
BACKGROUND High pre-pregnancy body mass index (ppBMI) has been linked to neurodevelopmental impairments in childhood. However, very few studies have investigated mechanisms in human cohorts. METHODS Among 1361 mother-child pairs in Project Viva, we examined associations of ppBMI categories with the Peabody Picture Vocabulary Test III [PPVT] and Wide Range Assessment of Visual Motor Abilities [WRAVMA] in early childhood (median 3.2y); and with the Kaufman Brief Intelligence test (KBIT) and WRAVMA in mid-childhood (7.7y). We further examined the role of maternal inflammation in these associations using the following measures from the 2nd trimester of pregnancy: plasma C-reactive protein (CRP), dietary inflammatory index (DII), and plasma omega-6 (n-6): n-3 fatty acid ratio. RESULTS Children of mothers with prenatal obesity (ppBMI ≥30 kg/m2) had WRAVMA scores that were 2.1 points lower (95% CI: -3.9, -0.2) in early childhood than children of normal weight mothers (ppBMI 18.5-<25 kg/m2), in a covariate adjusted model. This association was attenuated when we additionally adjusted for maternal CRP (β -1.8 points; 95% CI: -3.8, 0.2) but not for other inflammatory markers. PpBMI was not associated with other cognitive outcomes. CONCLUSION Maternal inflammation may modestly mediate the association between maternal obesity and offspring visual motor abilities.

[PMID: 31127822 PMCID: PMC6656419 DOI: 10.1210/jc.2018-02550] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/26/2018] [Accepted: 04/17/2019] [Indexed: 01/12/2023]
Abstract
CONTEXT Vitamin D may be important for prenatal programming of insulin and glucose regulation, but maternal vitamin D deficiency during pregnancy is common. OBJECTIVE We examined associations of early vitamin D status with markers of fetal insulin secretion (cord blood insulin and c-peptide). We hypothesized that maternal 25-hydroxyvitamin D (25(OH)D) during pregnancy and cord blood 25(OH)D would both be positively associated with cord blood insulin and c-peptide. METHODS We studied mother-newborn pairs from two cohorts: Project Viva (862 pairs included) and Genetics of Glucose Regulation in Gestation and Growth (Gen3G, 660 pairs included). We analyzed associations of the cord blood hormones with maternal 25(OH)D using generalized additive models with nonlinear spline terms and with cord blood 25(OH)D using multivariable linear regression models. RESULTS 25(OH)D levels were <75 nmol/L in over 70% of mothers and 85% of newborns. Maternal and cord blood 25(OH)D levels were correlated: r=0.58 in Project Viva and 0.37 in Gen3G. Maternal 25(OH)D had an inverted U-shaped relationship with cord blood insulin and c-peptide in both cohorts. Cord blood 25(OH)D had a linear relationship with the cord blood hormones. In fully adjusted models, each 10-nmol/L increase in cord blood 25(OH)D was associated with higher cord blood insulin and c-peptide concentrations: 3.7% (95% CI: (0.09, 7.5) and 3.2% (95% CI: 0.8, 5.6), respectively in Project Viva; 2.2% (95% CI: -0.1, 4.6) and 3.6% (95% CI: 1.0, 6.3), respectively in Gen3G. CONCLUSIONS Vitamin D may play a role in regulating fetal insulin secretion, potentially impacting glucose regulation and growth.

Dietary behaviors throughout childhood are associated with adiposity and estimated insulin resistance in early adolescence: a longitudinal study. Int J Behav Nutr Phys Act 2018; 15:129. [PMID: 30558613 PMCID: PMC6296122 DOI: 10.1186/s12966-018-0759-0] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2018] [Accepted: 12/03/2018] [Indexed: 12/27/2022] Open
Abstract
BACKGROUND Despite the growing prevalence of excess weight and prediabetes in children, the contributing role of dietary behaviors throughout childhood remains poorly understood. We examined longitudinal associations of dietary behaviors throughout childhood with adiposity and estimated insulin resistance (HOMA-IR) in adolescence. METHODS Among 995 children from Project Viva, a pre-birth cohort, we examined associations of child dietary behaviors (frequency of eating breakfast, fast food, family dinner, and eating meals while watching television) reported annually throughout childhood (from ages 4 to 11 years) with body mass index z-score (BMI-z; n = 991), waist circumference (WC; n = 995), DXA overall and central adiposity measurements (n = 721), and HOMA-IR (n = 579) in early adolescence (13.2 ± 0.9 years old). We used mixed effects models adjusted for potential confounders. RESULTS Eating breakfast daily throughout childhood was associated with lower BMI-z and DXA-measured overall and central adiposity in boys and girls (e.g. for whole-body fat %: β - 1.43% [95% CI: -2.42, - 0.45] and - 1.47% [- 2.25, - 0.68]), and with lower HOMA-IR in boys (% difference - 15.6% [- 22.7, - 7.9]). Daily family dinner and eating fast food less than once per week throughout childhood were both associated with lower BMI-z and adiposity in girls (for BMI-z: β - 0.17 units [- 0.24, - 0.11] and β - 0.09 units [- 0.17, - 0.02]) and lower insulin resistance in boys (% difference - 7.3% [- 12.4,- 1.8] and - 7.6% [- 13.2, - 1.7]). Finally, eating meals while watching television < 1/week throughout childhood was associated with lower adolescent adiposity (e.g. WC: - 1.55 cm [- 2.39, - 0.71]) and HOMA-IR (% difference: - 10.7% [- 15.8, - 5.2]) in boys. CONCLUSION Healthful dietary behaviors throughout childhood are associated with less adiposity and lower estimated insulin resistance in early adolescence. TRIAL REGISTRATION NCT02820402.

Abstract
BACKGROUND Of the various barriers to breastfeeding, limited information is available on the relationship between prenatal stress and breastfeeding. This study investigates the association between prenatal stressful life event (SLE) exposure and breastfeeding initiation postpartum. MATERIALS AND METHODS Using Rhode Island Pregnancy Risk Assessment Monitoring System data from 2012 to 2014, SLE was defined as self-report of prenatal exposure to 14 predefined life events such as job loss or illness. Exposure to SLE was categorized by number and type of events. Multivariable logistic regression was performed to assess the relationship between SLE and breastfeeding initiation. Results accounted for complex survey design and were adjusted for maternal and infant characteristics (age, race, ethnicity, insurance, delivery type, parity, gestational age, birth weight for gestational age, and neonatal intensive care unit admission). RESULTS Among 3,353 respondents, 86% reported breastfeeding initiation, 74% reported exposure to ≥1 SLE, and 17% reported exposure to ≥4 SLE. Decreased odds of breastfeeding initiation were associated with prenatal exposure to ≥4 SLE (adjusted odds ratio [aOR] 0.67; 95% confidence interval [CI]: 0.48-0.95), emotional stressors (aOR 0.77; 95% CI: 0.61-0.98), and traumatic stressors (aOR 0.68; 95% CI: 0.50-0.91). CONCLUSION This study underscores the impact of exposure to prenatal SLE on breastfeeding initiation among postpartum women. Findings may assist providers in identifying at-risk women for anticipatory guidance to improve breastfeeding rates.

Abstract
PURPOSE Prepregnancy obesity and weight changes accompanying pregnancy (gestational weight gain and postpartum weight retention) may be associated with risk of maternal depressive symptoms during pregnancy and in the postpartum. The few studies that have examined these relationships report conflicting findings. METHODS We studied pregnant (n = 2112) and postpartum (n = 1686) women enrolled in Project Viva. We used self-reported prepregnancy and postpartum weight and measured prenatal weight to calculate prepregnancy body mass index (BMI), gestational weight gain (GWG), and postpartum weight retention at 6 months after birth. We assessed elevated depressive symptoms (EDS) with the Edinburgh Postnatal Depression Scale (≥13 on 0-30 scale) at midpregnancy and 6 months postpartum. We used logistic regression to estimate the odds of prenatal and postpartum EDS in relation to prepregnancy BMI, GWG, and postpartum weight retention. RESULTS A total of 214 (10%) participants experienced prenatal EDS and 151 (9%) postpartum EDS. Neither prepregnancy BMI nor GWG was associated with prenatal EDS. Prepregnancy obesity (BMI ≥ 30 kg per m2) was associated with higher odds of postpartum EDS (odds ratio = 1.69, 95% confidence interval, 1.01-2.83) compared to normal prepregnancy weight in a model adjusted for age, race/ethnicity, nativity, education, marital status, household income, parity, pregnancy intention, and smoking. CONCLUSIONS Prepregnancy obesity is associated with elevated depressive symptoms in the postpartum period. Given the current obesity epidemic in the US and the consequences of perinatal depression, additional prevention and screening efforts in this population may be warranted.

Higher Maternal Protein Intake during Pregnancy Is Associated with Lower Cord Blood Concentrations of Insulin-like Growth Factor (IGF)-II, IGF Binding Protein 3, and Insulin, but Not IGF-I, in a Cohort of Women with High Protein Intake. J Nutr 2017; 147:1392-1400. [PMID: 28592512 DOI: 10.3945/jn.117.250589] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2017] [Revised: 04/07/2017] [Accepted: 05/12/2017] [Indexed: 01/10/2023] Open
Abstract
Background: Prenatal exposure to dietary protein may program growth-regulating hormones, consequently influencing early-life growth patterns and later risk of associated chronic diseases. The insulin-like growth factor (IGF) axis is of particular interest in this context given its influence on pre- and postnatal growth and its sensitivity to the early nutritional environment.Objective: Our objective was to examine associations of maternal protein intake during pregnancy with cord blood concentrations of IGF-I, IGF-II, IGF binding protein-3 (IGFBP-3), and insulin.Methods: We studied 938 mother-child pairs from early pregnancy through delivery in the Project Viva cohort. Using multivariable linear regression models adjusted for maternal race/ethnicity, education, income, smoking, parity, height, and gestational weight gain and for child sex, we examined associations of second-trimester maternal protein intake [grams per kilogram (weight before pregnancy) per day], as reported on a food frequency questionnaire, with IGF-I, IGF-II, IGFBP-3, and insulin concentrations in cord blood. We also examined how these associations may differ by child sex and parity.Results: Mothers were predominantly white (71%), college-educated (64%), and nonsmokers (67%). Mean ± SD protein intake was 1.35 ± 0.35 g ⋅ kg-1 ⋅ d-1 Each 1-SD increment in second-trimester protein intake corresponded to a change of -0.50 ng/mL (95% CI: -2.26, 1.26 ng/mL) in IGF-I and -0.91 μU/mL (95% CI: -1.45, -0.37 μU/mL) in insulin. Child sex and parity modified associations of maternal protein intake with IGF-II and IGFBP-3: protein intake was inversely associated with IGF-II in girls (P-interaction = 0.04) and multiparous mothers (P-interaction = 0.05), and with IGFBP-3 in multiparous mothers (P-interaction = 0.04).Conclusions: In a cohort of pregnant women with relatively high mean protein intakes, higher intake was associated with lower concentrations of growth-promoting hormones in cord blood, suggesting a pathway that may link higher protein intake to lower fetal growth. This trial was registered at clinicaltrials.gov as NCT02820402.

First and second trimester gestational weight gains are most strongly associated with cord blood levels of hormones at delivery important for glycemic control and somatic growth. Metabolism 2017; 69:112-119. [PMID: 28285640 PMCID: PMC5354298 DOI: 10.1016/j.metabol.2017.01.019] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/05/2016] [Revised: 01/09/2017] [Accepted: 01/10/2017] [Indexed: 11/22/2022]
Abstract
BACKGROUND Excessive gestational weight gain (GWG) during pregnancy is associated with adverse outcomes for mothers and offspring. Early, mid, and late pregnancy GWGs have different associations with fetal growth and later life adiposity, but associations with cord blood hormones, which might predict later health, are not well studied. METHODS In 978 pregnant women from the pre-birth Project Viva cohort, we calculated trimester-specific GWG using clinically recorded prenatal weights. Outcomes were levels of umbilical cord blood hormones related to fetal and postnatal growth. We used linear regression models adjusted for maternal race/ethnicity, pre-pregnancy BMI, parity, education, pregnancy smoking status and child sex; 2nd and 3rd trimester models were additionally adjusted for GWG in prior trimesters. RESULTS Mean±SD pre-pregnancy BMI was 24.9±5.5kg/m2, 30% were non-white, and 63% were college graduates. Mean±SD cord blood hormone levels were insulin-like growth factor [IGF]-1 (56.4±24.3ng/mL), IGF-2 (408.5±92.7ng/mL), IGFBP-3 (1084±318ng/mL), insulin (6.5±7.2 uU/mL), C-peptide (1.0±0.6ng/mL), leptin (9.0±6.6ng/mL) and adiponectin (28.7±6.8μg/mL). Mean±SD 1st, 2nd and 3rd trimester GWG rates were 0.22±0.22, 0.49±0.19 and 0.46±0.22kg/wk. Greater 1st trimester GWG (per 0.2kg/wk) was associated with higher insulin (0.5 uU/mL; 95% CI 0.1, 0.9) and C-peptide (0.06ng/mL; 95% CI 0.02, 0.09) and lower adiponectin (-0.4μg/mL; 95% CI -0.9, 0.0). Greater 2nd trimester GWG (per 0.2kg/wk) was associated with higher IGF-1 (2.3ng/mL; 95% CI 0.6, 4.0), IGF-2 (7.9ng/mL; 95% CI 1.2, 14.6), IGFBP-3 (41.6ng/mL; 95% CI 19.4, 63.7) and leptin (0.9ng/mL; 0.4, 1.4). 3rd trimester GWG was not associated with cord blood hormones. CONCLUSION 1st trimester weight gain appears to matter more for cord blood hormones related to offspring glucose/insulin regulation, whereas 2nd trimester gain matters more for hormones related to growth and adiposity.

Abstract
Self-reported maternal weight is error-prone, and the context of pregnancy may impact error distributions. This systematic review summarizes error in self-reported weight across pregnancy and assesses implications for bias in associations between pregnancy-related weight and birth outcomes. We searched PubMed and Google Scholar through November 2015 for peer-reviewed articles reporting accuracy of self-reported, pregnancy-related weight at four time points: prepregnancy, delivery, over gestation and postpartum. Included studies compared maternal self-report to anthropometric measurement or medical report of weights. Sixty-two studies met inclusion criteria. We extracted data on magnitude of error and misclassification. We assessed impact of reporting error on bias in associations between pregnancy-related weight and birth outcomes. Women underreported prepregnancy (PPW: -2.94 to -0.29 kg) and delivery weight (DW: -1.28 to 0.07 kg), and over-reported gestational weight gain (GWG: 0.33 to 3 kg). Magnitude of error was small, ranged widely, and varied by prepregnancy weight class and race/ethnicity. Misclassification was moderate (PPW: 0-48.3%; DW: 39.0-49.0%; GWG: 16.7-59.1%), and overestimated some estimates of population prevalence. However, reporting error did not largely bias associations between pregnancy-related weight and birth outcomes. Although measured weight is preferable, self-report is a cost-effective and practical measurement approach. Future researchers should develop bias correction techniques for self-reported pregnancy-related weight.

Abstract
Background Few studies have examined sex-specific associations of maternal gestational glycemia with cord blood hormones, which might predict later health. Methods In 976 women without pre-existing diabetes in the Project Viva cohort, we used linear regression to examine associations of maternal gestational glycemia with cord hormone concentrations, adjusted for maternal characteristics and stratified by infant sex. Results A total of 6.1% of women had gestational diabetes mellitus (GDM), 8.8% isolated hyperglycemia, 3.2% gestational impaired glucose tolerance, and 81.9% were normoglycemic. In boys, compared with infants of normoglycemic mothers, infants of GDM mothers had higher cord levels of IGF-2 (β 35.55 ng/mL; 95% CI: 2.60, 68.50), IGFBP-3 (111.2 ng/mL; 5.53, 216.8), insulin (4.66 uU/mL; 2.38, 6.95), C-peptide (0.46 ng/mL; 0.25, 0.67), and leptin (3.51 ng/mL; 1.37, 5.64), but lower IGF-1 (-6.71 ng/mL; -12.7, - 0.76, adjusted for IGFBP-3). In girls, GDM offspring had higher cord blood levels of IGF-1 adjusted for IGFBP-3 (12.45 ng/mL; 4.85, 20.04). Boys, but not girls, of mothers with abnormal glucose tolerance but not GDM also had higher levels of some hormones. Conclusion GDM was associated with growth factors and adipokines in cord blood from boys, but only IGF-1 in girls. These findings suggest sex differences in responses to fetal overnutrition.

Abstract
OBJECTIVE It is unclear how specific periods of gestational weight gain (GWG) during pregnancy relate to childhood adiposity. The goal of this study was to assess the differential impact of GWG timing on childhood body composition. METHODS In 979 mother-child pairs from the pre-birth Project Viva cohort, trimester-specific GWG was calculated using clinically recorded weights. Outcomes included body mass index (BMI) z-score, dual X-ray absorptiometry fat mass index (kg/m(2) ), and fat-free mass index (kg/m(2) ) in mid-childhood. Linear regression models were used to assess associations of each trimester's GWG (per 0.2 kg/week) with childhood outcomes, adjusted for maternal prepregnancy BMI, sociodemographic variables, lifestyle, and GWG in prior trimester(s). RESULTS Mean (SD) first trimester GWG was 0.22 (0.22) kg/week, second trimester 0.49 (0.18) kg/week, and third trimester 0.47 (0.20) kg/week. Faster first trimester GWG was associated with higher BMI z-score (0.06 units [95% CI: 0.01-0.12] per 0.2 kg/week) and with higher adiposity according to all indices; associations were strongest in women with prepregnancy BMI >30 kg/m(2) . Faster second trimester GWG was associated with higher BMI z-score (0.11 [0.04-0.18]), fat mass (fat mass index = 0.16 [0.02-0.31] kg/m(2) ), and lean mass (fat-free mass index = 0.11 [0.01-0.22] kg/m(2) ). Third trimester GWG was not associated with childhood adiposity. CONCLUSIONS These results reinforce the importance of addressing appropriate GWG in early pregnancy.
