Project description:We sought to investigate whether early mid pregnancy visceral and subcutaneous fat depths measured by ultrasound were associated with infant birth size, independent of early pregnancy BMI. A cohort study was performed at Uppsala University Hospital, Sweden, between 2015-2018. Visceral and subcutaneous fat depths were measured at the early second-trimester anomaly scan in 2498 women, giving birth to singleton, term infants. Primary outcomes were birthweight and LGA (birthweight standard deviation score > 90th percentile in the cohort). Linear and logistic regression models were used, adjusted for BMI, age, smoking, parity, maternal country of birth, gestational age and infant sex. A 5-mm increase in visceral fat depth was associated with an increase in birthweight of 8.3 g [95% confidence interval (CI) 2.5 - 14.1 g], after adjustments, and a 6% increase in the adjusted odds of having an infant born LGA (OR 1.06, CI 1.02-1.11). There was no association between subcutaneous fat depth and birthweight or LGA after covariate adjustments. Hence, visceral fat depth measured by ultrasound in early mid pregnancy was associated with excessive fetal growth, independent of early pregnancy BMI, and may be useful in models for predicting LGA infants.

Project description:While recent studies show that maternal use of snus during pregnancy is increasing, the potential effects on infant birth size is less investigated, with conflicting results. We aimed to determine if maternal use of snus during pregnancy influences the infant anthropometric and proportional size measures at birth. In 2313 mother-child pairs from the population-based, mother-child birth cohort PreventADALL (Preventing Atopic Dermatitis and ALLergies) in Norway and Sweden, we assessed nicotine exposure by electronic questionnaire(s) at 18 and 34 weeks of pregnancy, and anthropometric measurements at birth. Associations between snus exposure and birth size outcomes were analysed by general linear regression. Birthweight was not significantly different in infants exposed to snus in general, and up to 18 weeks of pregnancy in particular, when adjusting for relevant confounders including maternal age, gestational age at birth, pre-pregnancy body mass index, parity, fetal sex and maternal gestational weight gain up to 18 weeks. We found no significant effect of snus use on the other anthropometric or proportional size measures in multivariable linear regression models. Most women stopped snus use in early pregnancy. Exposure to snus use in early pregnancy, with most women stopping when knowing about their pregnancy, was not associated with birth size. We were unable to conclude on effects of continued snus use during pregnancy because of lack of exposure in our cohort.

Project description:BACKGROUND/OBJECTIVES:Maternal obesity impacts fetal growth as early as second trimester of pregnancy, yet little is known about the molecular mechanisms involved. We aimed to examine associations between maternal adipokines throughout pregnancy and neonatal size by prepregnancy obesity status. METHODS:In a prospective cohort of 2802 U.S. pregnant women from the NICHD Fetal Growth Studies-Singleton Cohort (2009-2013), biospecimens were analyzed in a matched case-control subset of 321 women. Blood was collected at 10-14, 15-26 (fasting), 23-31, and 33-39 gestational weeks. Plasma leptin and soluble leptin receptor (sOB-R) and total and high-molecular-weight (HMW)-adiponectin were measured. Free leptin was calculated as leptin/sOB-R. Birthweight was abstracted from medical records. Neonatal length and skinfolds were measured. RESULTS:Leptin and sOB-R in late pregnancy tended to be positively and negatively associated with neonatal length, respectively, while free leptin throughout pregnancy tended to be positively associated with length. Free leptin associations with neonatal length were differential by obesity (i.e., inversely among women without obesity and positively among women with obesity). A per unit increase in free leptin at 33-39 weeks was associated with a shorter neonatal length by -0.55?cm (95%CI, -0.83, -0.28) in women without obesity and longer length by 0.49?cm (95%CI, 0.34, 0.65) in women with obesity. HMW-adiponectin at 33-39 weeks was inversely associated with neonatal length (??=?-1.29?cm; 95%CI, -1.74, -0.85) and skinfold thickness (??=?-1.46?mm; 95%CI, -1.58, -0.56) among women with obesity. Free leptin across pregnancy tended to be negatively associated with neonatal skinfold thickness among women without obesity, while free leptin in early pregnancy was positively associated with skinfold thickness. CONCLUSIONS:Maternal adipokines were associated with multiple pathways that influence neonatal size including length and adiposity, which differed in timing across pregnancy and by prepregnancy obesity. These findings provide new potential insights into mechanisms and timing by which maternal obesity may impact fetal growth.

Project description:The objective of this study was to examine the associations of early mid-pregnancy ultrasound measured visceral and subcutaneous fat depths with blood-based protein biomarkers. This was a cross-sectional study including 201 pregnant women at Uppsala University Hospital, Sweden. The mean age of the women was 31.0 years, and 57.7% were nulliparous. Maternal visceral and subcutaneous fat depths were measured by ultrasound at the early second-trimester anomaly scan. A non-fasting blood sample was collected in conjunction with the second-trimester anomaly scan, and the Olink cardiovascular II panel was used to measure 92 blood-based protein biomarkers in the sample. Cross-sectional associations of visceral and subcutaneous fat depths with blood-based protein biomarkers were examined using Mann-Whitney U tests with false discovery rate adjustments. In addition, linear regression analyses adjusting for maternal age, parity, and early pregnancy body mass index were performed. The results showed differences in one biomarker between women with elevated (≥ 52 mm) versus normal (< 52 mm) visceral fat depth, and in three biomarkers between women with elevated (≥ 22 mm) versus normal (< 22 mm) subcutaneous fat depth. Hence, levels of blood-based protein biomarkers differ between pregnant women with dissimilar body fat distributions, which might reflect disparities in biological pathways.

Project description:BackgroundEffects of maternal leisure time physical activity (LTPA) on paediatric obesity are unknown. The objective of this study was to examine associations of maternal LTPA with offspring overall and central adiposity in mid-childhood.MethodsWe analysed data from 802 mother-child dyads from Project Viva, a prospective pre-birth cohort study. Women reported average weekly LTPA before and during mid-pregnancy. At age 7-10 years, we measured fat, truncal fat and lean mass with dual-energy X-ray absorptiometry. Using multivariable linear regression, we examined associations of maternal LTPA with offspring adiposity, adjusting for child age and sex, maternal race/ethnicity, education, age, pre-pregnancy body mass index, marital status and smoking status.ResultsMean (standard deviation) of LTPA before and during mid-pregnancy were 9.5 (8.1) and 7.1 (7.0) h week(-1) . At mean age 7.8 (0.8) years, childhood fat, truncal fat and lean mass indices were 4.3 (1.8), 1.4 (0.8) and 12.9 (1.4) kg m(-2) . We did not find that higher maternal LTPA was associated with lower child adiposity outcomes. For example, compared with 0-3 h week(-1) of LTPA during mid-pregnancy, children of mothers with +8 h week(-1) had fat mass index 0.07 kg m(-2) (95% confidence interval: -0.22, 0.36). In analyses of within-person LTPA change from before to mid-pregnancy, compared with +2 h week(-1) decrease in LTPA, increased LTPA (2 ± h week(-1) ) was associated with a 0.09 kg m(-2) fat mass index (-0.25, 0.43).ConclusionsContrary to our hypothesis, higher LTPA before and during mid-pregnancy, and the change between them, were not associated with lower adiposity in mid-childhood.

Project description: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.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).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.These results reinforce the importance of addressing appropriate GWG in early pregnancy.

Project description:Background and aimImpaired lung function in early infancy is associated with later wheeze and asthma, while fetal thoracic circumference (TC) predicts severity of neonatal lung hypoplasia. Exploring fetal origins of lung function in infancy, we aimed to determine if fetal TC in mid-pregnancy was associated with infant lung function.MethodsFrom the prospective Scandinavian general population-based PreventADALL mother-child birth cohort, all 851 3-month-old infants with tidal flow-volume measurements in the awake state and ultrasound fetal size measures at 18 (min-max 16-22) weeks gestational age were included. Associations between fetal TC and time to peak tidal expiratory flow to expiratory time (tPTEF /tE ) were analyzed in linear regression models. To account for gestational age variation, we adjusted TC for simultaneously measured general fetal size, by head circumference (TC/HC), abdominal circumference (TC/AC), and femur length (TC/FL). Multivariable models were adjusted for maternal age, maternal asthma, pre-pregnancy body mass index, parity, nicotine exposure in utero, and infant sex.ResultsThe infants (47.8% girls) were born at mean (SD) gestational age of 40.2 (1.30) weeks. The mean (SD) tPTEF /tE was 0.39 (0.08). The mean (SD) TC/HC was 0.75 (0.04), TC/AC 0.87 (0.04), and TC/FL 4.17 (0.26), respectively. Neither TC/HC nor TC/AC were associated with infant tPTEF /tE while a week inverse association was observed between TC/FL and tPTEF /tE ( β^$\hat{\beta }$ = -0.03, 95% confidence interval [-0.05, -0.007], p = 0.01).ConclusionMid-pregnancy fetal TC adjusted for fetal head or abdominal size was not associated with tPTEF /tE in healthy, awake 3-month-old infants, while a weak association was observed adjusting for fetal femur length.

Project description:OBJECTIVES:To assess associations between maternal prenatal diet quality and infant adiposity. DESIGN:The design was a prospective birth cohort. SETTING:We used data from the Nurture study, a cohort of women and their infants residing in the southeastern USA. PARTICIPANTS AND EXPOSURE ASSESSMENT:Between 2013 and 2015, we enrolled 860 women between 20 and 36 weeks' gestation. After reconsenting at delivery and excluding women with implausible calorie intakes, we measured dietary intake using the Block food frequency questionnaire, and assessed diet quality using a modified Alternate Healthy Eating Index 2010 (AHEI-2010), which assessed intake of 10 food categories, including fruits, vegetables, whole grains, nuts/legumes, fats, meats, beverages and sodium (excluding alcohol). OUTCOMES:We assessed birth weight for gestational age z-score, small and large for gestational age, low birth weight and macrosomia. Outcomes at 6 and 12 months were weight-for-length z-score, sum of subscapular and triceps skinfold thickness (SS+TR) and subscapular-to-triceps skinfold ratio (SS:TR). RESULTS:Among mothers, 70.2% were black and 20.9% were white; less than half (45.2%) reported having a high school diploma or less. Among infants, 8.7% were low birth weight and 8.6% were small for gestational age. Unadjusted estimates showed that a higher AHEI-2010 score, was associated with a higher birth weight for gestational z-score (β=0.01; 95% CI 0.002 to 0.02; p=0.02) and a greater likelihood of macrosomia (OR=1.04; 95% CI 1.004 to 1.09; p=0.03). After adjustment, maternal diet quality was not associated with infant adiposity at birth, 6 or 12 months. CONCLUSIONS:Although poor maternal diet quality during pregnancy was not associated with infant adiposity in our study, maternal diet during pregnancy may still be an important and modifiable factor of public health importance.
