<h4>Background</h4>Previous reports of associations of maternal seafood intake with fetal growth were inconsistent. Further, little is known whether associations differ across seafood subtypes or fetal growth indices.<h4>Methods</h4>Among 3141 participants of the Omega study, a pregnancy cohort study, we investigated associations of periconceptional shell, lean, and fatty fish intake with fetal growth indices. We categorised food frequency questionnaire reported seafood intake into frequencies o ...[more]

Project description:OBJECTIVE:To investigate associations of maternal periconceptional shellfish, lean fish and fatty fish intake with risk of pregnancy complications. DESIGN:In this prospective cohort study, we collected information on intake of seafood subtypes using FFQ. We categorized seafood intake into frequencies of 1 servings/week. We ascertained gestational hypertension, pre-eclampsia, gestational diabetes and preterm birth diagnoses from medical records. Using generalized linear models with a log link, the Poisson family and robust standard errors, we estimated risk ratios and 95 % confidence intervals across seafood intake categories. SETTING:The Omega study, a study of risk factors for pregnancy complications among women recruited from prenatal clinics in Washington State, USA, 1996-2008. SUBJECTS:The current study included 3279 participants from the Omega study. RESULTS:Median (interquartile range) shellfish, lean fish and fatty fish intake was 0·3 (0-0·9), 0·5 (0-1·0) and 0·5 (0·1-1·0) servings/week, respectively. Lean fish intake of >1 servings/week (v. <0·2 servings/month) was associated with a 1·55-fold higher risk of preterm birth (95 % CI 1·04, 2·30) and was not associated with the other pregnancy complications. Higher intake of seafood (total or other subtypes) was not associated with pregnancy complications (separately or combined). CONCLUSIONS:Higher intake of lean fish, but not fatty fish or shellfish, was associated with a higher risk of preterm birth; these findings may have significance for preterm birth prevention. Studies of mechanisms and potential contributing factors (including seafood preparation and nutrient/contaminant content) are warranted.

Project description:Study questionIs periconceptional multiple-micronutrient supplement (MMS) use including folic acid (FA) compared to FA use only associated with increased embryonic growth, development, and birth weight in a high-risk population?Summary answerWomen with MMS intake show no significant differences in first-trimester morphological embryo development, but increased first-trimester embryonic growth trajectories and fewer neonates born small for gestational age (SGA), less than the 3rd percentile (<p3), compared to women using only FA.What is known alreadyPericonceptional maternal FA intake in the general population is associated with increased embryonic and fetal growth, and reduced risks of neural tube defects, other congenital malformations, low birth weight, and neonates born SGA.Study design, size, durationA prospective tertiary hospital-based cohort study (the Rotterdam Periconceptional Cohort) was conducted from January 2010 to December 2020.Participants/materials, setting, methodsWe included 1076 women from the Rotterdam Periconceptional Cohort, before 10 weeks of pregnancy with follow-up until delivery. Embryonic growth was assessed by measurement of crown-rump length (CRL) and embryonic volume (EV), and embryonic morphology was described by Carnegie stages using longitudinal three-dimensional ultrasound scans and virtual reality techniques. Birth outcomes were extracted from medical records. General characteristics and supplement use were extracted from research questionnaires.Main results and the role of chanceThis study showed increased embryonic growth trajectories (adjusted models, CRL: β = 0.052, 95% CI 0.012-0.090, EV: β = 0.022, 95% CI 0.002-0.042) in women using MMS compared to those using only FA. Moreover, a 45% reduced risk of a neonate-born SGA (<p3) was shown in women using MMS compared to FA users (adjusted OR = 0.546, 95% CI 0.308, 0.969). Embryonic morphological development (Carnegie stages) and the occurrence of miscarriages did not differ between women using MMS or solely FA.Limitations, reasons for cautionFollowing the heterogeneity of the composition and dose of MMS preparations, it is unclear which specific micronutrient, combination, or dose explains the increased embryonic growth trajectory and reduction in risk for SGA. This also hampers the possibility of differentiating between the effects of FA alone or as a component of MMS.Wider implications of the findingsOur findings emphasize the importance of periconceptional maternal MMS use as a potential preventative intervention against reduced embryonic growth and neonates born SGA. Therefore, we recommend the periconceptional use of MMS in women at risk of inadequate micronutrient intake. However, awareness of potentially harmful side effects of high doses and combinations of micronutrients is essential, therefore the optimal composition and dose need to be investigated, and careful surveillance is recommended.Study funding/competing interest(s)This research was funded by the Department of Obstetrics and Gynaecology, Erasmus MC, University Medical Center, Rotterdam, The Netherlands, and the ZonMw grant Open Competition 2018 (09120011910046).

Project description:ContextMarine long-chain omega-3 fatty acids have been positively related to markers of fecundity in both men and women. However, seafood, their primary food source, can also be a source of toxicants, which could counteract the reproductive benefits.ObjectiveTo examine the relationship of male and female seafood intake with time to pregnancy (TTP).DesignOur prospective cohort study included 501 couples planning pregnancy, who participated in the Longitudinal Investigation of Fertility and the Environment study (2005 to 2009) and were followed up for ≤1 year or until pregnancy was detected. Seafood intake was collected daily during follow-up in journals.SettingCouples residing in Michigan and Texas were recruited using population-based sampling frameworks.Main outcome measuresThe primary outcome was the TTP, determined using an in-home pregnancy test. A secondary outcome was sexual intercourse frequency (SIF) as recorded in the daily journals.ResultsCouples with male and female partners who consumed eight or more seafood servings per cycle had 47% (95% CI, 7% to 103%) and 60% (95% CI, 15% to 122%) greater fecundity (shorter TTP) than couples with male and female partners who consumed one or fewer seafood servings per cycle. Couples with both partners consuming eight or more seafood servings per cycle had 61% (95% CI, 17% to 122%) greater fecundity than couples consuming less. Male and female partners with the highest seafood intake (eight or more servings per cycle) also had 22% greater SIF.ConclusionsGreater male and female seafood intake was associated with a higher SIF and fecundity among a large prospective cohort of couples attempting pregnancy.

Project description:ObjectiveUltraprocessed foods (UPFs) have been linked with obesity and cardiometabolic diseases in the general population but are understudied in pregnancy. We examined associations of UPF intake with gestational weight gain (GWG), glycemic, and blood pressure outcomes in pregnancy.Research design and methodsPregnant women (n = 1,948) in a prospective U.S. cohort self-reported the past 3-month diet using a food frequency questionnaire (FFQ) at 8-13 weeks of gestation. The intake quantity (g/day) of foods and beverages identified as UPFs was ranked into quartiles. Associations of UPFs were evaluated, after adjusting for confounders, with 2nd and 3rd trimester Institute of Medicine (IOM) GWG categories, gestational diabetes mellitus (GDM), and hypertensive disorders of pregnancy (GHTN). Secondary outcomes included GWG rate, glucose challenge test 1-h glucose, and blood pressure trajectories from linear mixed models.ResultsA total of 492 (25.2%) and 699 women (35.9%) had 2nd and 3rd trimester excessive GWG, respectively, and 85 women (4.4%) had GDM and 63 (3.2%) had severe hypertension or preeclampsia. UPF intake was not associated with higher odds of excessive GWG (quartile 4 vs. 1: adjusted odds ratio 0.68 [95% CI 0.44, 1.05], P-trend = 0.10 for 2nd trimester) or GDM risk (quartile 4 vs. 1: adjusted risk ratio 0.99 [95% CI 0.46, 2.11], P-trend = 0.85). Although UPF intake was positively associated with minor differences blood pressure trajectories, associations with GHTN were null.ConclusionsThe expected unfavorable association of higher UPF intake with excessive GWG, GDM, and GHTN was not observed in our cohort of low-risk pregnant women. These results are based on a limited sample size and require replication.

Project description:Maternal seafood intake is of great health interest since it constitutes an important source of n-3 fatty acids, but provides also an important pathway for fetal exposure to Hg. The objective of the present study was to determine associations between Hg contamination and both maternal seafood consumption and fetal growth in French pregnant women. Pregnant women included in the 'EDEN mother-child' cohort study answered FFQ on their usual diet in the year before and during the last 3 months of pregnancy, from which frequencies of seafood intake were evaluated. Total hair-Hg level was determined for the first 691 included women. Associations between Hg level, seafood intake and several neonatal measurements were studied using linear regressions adjusted for confounding variables. The median Hg level for mothers was 0.52 ?g/g. Maternal seafood intake was associated with Hg level (r 0.33; P < 0.0001). There was no association between Hg level and fetal growth in the whole sample of women, except for an early negative relationship with biparietal diameter. A positive association was found between seafood intake and fetal growth in overweight women only which remained unchanged after adjustment for Hg level (birth weight: +101 g for a difference of 1 sd in seafood consumption; P = 0.008). Although seafood intake was associated with Hg contamination in French pregnant women, the contamination level was low. There was no consistent association between Hg level and fetal growth. Taking into account Hg level did not modify associations between seafood intake and fetal growth.

Project description:Meat, including fish and shellfish, represents a valuable constituent of most balanced diets. Consumption of different types of meat and fish has been associated with both beneficial and adverse health effects. While white meats and fish are generally associated with positive health outcomes, red and especially processed meats have been associated with colorectal cancer and other diseases. The contribution of these foods to the development or prevention of chronic diseases is still not fully elucidated. One of the main problems is the difficulty in properly evaluating meat intake, as the existing self-reporting tools for dietary assessment may be imprecise and therefore affected by systematic and random errors. Dietary biomarkers measured in biological fluids have been proposed as possible objective measurements of the actual intake of specific foods and as a support for classical assessment methods. Good biomarkers for meat intake should reflect total dietary intake of meat, independent of source or processing and should be able to differentiate meat consumption from that of other protein-rich foods; alternatively, meat intake biomarkers should be specific to each of the different meat sources (e.g., red vs. white; fish, bird, or mammal) and/or cooking methods. In this paper, we present a systematic investigation of the scientific literature while providing a comprehensive overview of the possible biomarker(s) for the intake of different types of meat, including fish and shellfish, and processed and heated meats according to published guidelines for biomarker reviews (BFIrev). The most promising biomarkers are further validated for their usefulness for dietary assessment by published validation criteria.

Project description:PurposePrevious studies have shown an association between maternal fever in early pregnancy and neural tube defects (NTDs) such as spina bifida. Periconceptional folic acid intake has been shown to reduce the risk of these outcomes.MethodsUsing data from the Slone Epidemiology Center Birth Defects Study (1998-2015), we examined the impact of folic acid on the relationship between maternal fever in the periconceptional period (28 days before and after the last menstrual period) and NTDs. Logistic regression models were used to calculate adjusted odds ratios (ORs) and 95% confidence intervals (CIs).ResultsMothers of 375 cases and 8247 nonmalformed controls were included. We observed an elevated risk for NTDs for fever in the periconceptional period (OR: 2.4; 95% CI: 1.5-4.0). This association was weaker for mothers who reported consuming the recommended amount of folic acid (≥400 μg per day; OR: 1.8; 95% CI: 0.8-4.0) than mothers with low folic acid intake (<400 μg per day; OR: 4.2; 95% CI: 2.2-8.2).ConclusionsOur data support an association between maternal periconceptional fever and an increased risk for NTDs and also provide evidence that this association was attenuated for mothers who reported consuming folic acid at recommended levels in the periconceptional period.

Project description:ObjectivesTo examine the associations of maternal intake of fruits and vegetables (FVs), considering pesticide residue levels, with fetal growth.MethodsWe studied 1777 mothers (1275 white, 502 non-white) and their infants from Project Viva, a prospective pre-birth cohort (1999-2002). We categorized FVs as containing high or low pesticide residues using data from the US Department of Agriculture. We then used a food frequency questionnaire to estimate each participant's intake of high and low pesticide residue FVs in the first and second trimester. The primary outcomes were small-for-gestational-age (SGA; <10th percentile in birth-weight-for-gestational-age), large-for-gestational-age (LGA; ≥10th percentile in birth-weight-for-gestational-age) and preterm birth (gestational age <37 weeks). We also evaluated whether the associations between high pesticide residue FV intake and birth outcomes were modified by race/ethnicity.Results5.5% of newborns were SGA, 13.7% were LGA, and 7.3% were preterm. Intakes of high or low pesticide residue FVs, regardless of pregnancy trimester, were not associated with risks of SGA, LGA, or preterm birth. In addition, the associations of high pesticide FV intake with SGA and LGA were not modified by race/ethnicity. However, we observed heterogeneity in the relationship between first trimester high pesticide FV intake and risk of preterm birth by race/ethnicity (P value for interaction = 0.01), although this relationship did not persist after correction for multiple comparisons (Bonferroni corrected level of significance: P < 2.8 × 10-3).ConclusionsThere were no clear associations between high or low pesticide FV intake during pregnancy with SGA, LGA or preterm birth.

Project description:BackgroundFolic acid supplementation during pregnancy plays an important role in fetal growth and development. To our knowledge, no experimental study has examined the effect of folic acid on fetal brain growth in women who smoke cigarettes during pregnancy.ObjectivesThe aim of this study was to investigate the efficacy of higher-dose compared with standard-dose folic acid supplementation on prenatal fetal brain growth, measured by head circumference, brain weight, and brain-body weight ratio (BBR).DesignIn this randomly assigned, double-blind, controlled clinical trial, we recruited 345 smoking pregnant women attending a community health center in Tampa, FL between 2010 and 2014. Participants were randomly assigned in a 1:1 ratio to receive either 0.8 mg folic acid/d (standard of care at the study center) or 4 mg folic acid/d (higher strength). Participants were also enrolled in a smoking cessation program. A 2-level linear growth model was used to assess treatment effect and factors that predict intrauterine growth in head circumference over time. Multiple linear regression analyses were conducted to estimate the effect of higher-strength folic acid on head circumference at birth, fetal brain weight, and fetal BBRs.ResultsMothers who received the higher dose of folic acid had infants with a 1.18 mm larger mean head circumference compared with infants born to mothers who received the standard dose, but this difference was not statistically significant (P = 0.2762). Higher-dose folic acid also had no significant effect on brain weight. The BBR of infants of mothers who received higher-dose folic acid was, however, 0.33 percentage points lower than that for infants of mothers who received the standard dose of folic acid (P = 0.044).ConclusionsInfants of smokers in pregnancy may benefit from higher-strength maternal folic acid supplementation. We noted a decrease in the proportion of infants with impaired BBR among those on higher-dose folic acid. This trial was registered at clinicaltrials.gov as NCT01248260.

Project description:BackgroundAccurately identifying pregnancies with accelerated or diminished fetal growth is challenging and generally based on cross-sectional percentile estimates of fetal weight. Longitudinal growth velocity might improve identification of abnormally grown fetuses.ObjectiveWe sought to complement fetal size standards with fetal growth velocity, develop a model to compute fetal growth velocity percentiles for any given set of gestational week intervals, and determine association between fetal growth velocity and birthweight.Study designThis was a prospective cohort study with data collected at 12 US sites (2009 through 2013) from 1733 nonobese, low-risk pregnancies included in the singleton standard. Following a standardized sonogram at 10w0d-13w6d, each woman was randomized to 1 of 4 follow-up visit schedules with 5 additional study sonograms (targeted ranges: 16-22, 24-29, 30-33, 34-37, and 38-41 weeks). Study visits could occur ± 1 week from the targeted GA. Ultrasound biometric measurements included biparietal diameter, head circumference, abdominal circumference, and femur length, and estimated fetal weight was calculated. We used linear mixed models with cubic splines for the fixed effects and random effects to flexibly model ultrasound trajectories. We computed velocity percentiles in 2 ways: (1) difference between 2 consecutive weekly measurements (ie, weekly velocity), and (2) difference between any 2 ultrasounds at a clinically reasonable difference between 2 gestational ages (ie, velocity calculator). We compared correlation between fetal growth velocity percentiles and estimated fetal weight percentiles at 4-week intervals, with 32 (±1) weeks' gestation for illustration. Growth velocity was computed as estimated fetal growth rate (g/wk) between ultrasound at that gestational age and from prior visit [ie, for 28-32 weeks' gestational age: velocity = (estimated fetal weight 32-28)/(gestational age 32-28)]. We examined differences in birthweight by whether or not estimated fetal weight and estimated fetal weight velocity were <5th or ≥5th percentiles using χ2.ResultsFetal growth velocity was nonmonotonic, with acceleration early in pregnancy, peaking at 13, 14, 15, and 16 weeks for biparietal diameter, head circumference, femur length, and abdominal circumference, respectively. Biparietal diameter, head circumference, and abdominal circumference had a second acceleration at 19-22, 19-21, and 27-31 weeks, respectively. Estimated fetal weight velocity peaked around 35 weeks. Fetal growth velocity varied slightly by race/ethnicity although comparisons reflected differences for parameters at various gestational ages. Estimated fetal weight velocity percentiles were not highly correlated with fetal size percentiles (Pearson r = 0.40-0.41, P < .001), suggesting that these measurements reflect different aspects of fetal growth and velocity may add additional information to a single measure of estimated fetal weight. At 32 (SD ± 1) weeks, if both estimated fetal weight velocity and size were <5th percentile, mean birthweight was 2550 g; however, even when size remained <5th percentile but velocity was ≥5th percentile, birthweight increased to 2867 g, reflecting the important contribution of higher growth velocities. For estimated fetal weight ≥5th percentile, but growth velocity <5th, birthweight was smaller (3208 vs 3357 g, respectively, P < .001).ConclusionWe provide fetal growth velocity data to complement our previous work on fetal growth size standards, and have developed a calculator to compute fetal growth velocity. Preliminary findings suggest that growth velocity adds additional information over knowing fetal size alone.
