Project description:Childhood blood pressure (BP) is a strong predictor of later risk of cardiovascular disease. However, few studies have assessed dynamic BP trajectories throughout the early-life period. We investigated the relationship between early-life factors and systolic BP (SBP) from infancy to adolescence using linear spline mixed-effects models among 1,370 children from Project Viva, a Boston, Massachusetts-area cohort recruited in 1999-2002. After adjusting for confounders and child height, we observed higher SBP in children exposed to gestational diabetes mellitus (vs. normoglycemia; age 3 years: β = 3.16 mm Hg (95% confidence interval (CI): 0.28, 6.04); age 6 years: β = 1.83 mm Hg (95% CI: 0.06, 3.60)), hypertensive disorders of pregnancy (vs. normal maternal BP; age 6 years: β = 1.39 mm Hg (95% CI: 0.10, 2.67); age 9 years: β = 1.84 mm Hg (95% CI: 0.34, 3.34); age 12 years: β = 1.70 mm Hg (95% CI: 0.48, 2.92)), higher neonatal SBP (per 10-mm Hg increase; age 3 years: β = 1.26 mm Hg (95% CI: 0.42, 2.09); age 6 years: β = 1.00 mm Hg (95% CI: 0.49, 1.51); age 9 years: β = 0.75 mm Hg (95% CI: 0.17, 1.33)), and formula milk in the first 6 months of life (vs. breast milk only; age 12 years: β = 2.10 mm Hg (95% CI: 0.46, 3.74); age 15 years: β = 3.52 mm Hg (95% CI: 1.40, 5.64); age 18 years: β = 4.94 mm Hg (95% CI: 1.88, 7.99)). Our findings provide evidence of programming of offspring SBP trajectories by gestational diabetes, hypertensive disorders of pregnancy, and formula milk intake and of neonatal BP being a potentially useful marker of childhood BP. These factors could be relevant in identifying children who are at risk of developing elevated BP.

Project description:ObjectiveThe purpose of this article is to characterize metabolomic profiles of four overweight/obesity (OWOB) and metabolic risk (MetRisk) phenotypes among 524 adolescents aged approximately 13 years.MethodsA four-level phenotype variable (non-OWOB and low MetRisk, non-OWOB and high MetRisk, OWOB and low MetRisk, and OWOB and high MetRisk) was created using BMI percentile to define OWOB, and high versus low MetRisk was derived as the fourth versus first to third quartiles of a z score calculated as the average of five externally standardized z scores for waist circumference, homeostatic model assessment of insulin resistance, high-density lipoprotein, triglycerides, and systolic blood pressure. Then associations of nine metabolite patterns derived from principal components analysis with phenotype after accounting for age, sex, race, and pubertal status were evaluated.ResultsFive metabolite patterns differed with respect to phenotype: factor 1 consisted of long-chain fatty acids and was lower among non-OWOB and high MetRisk (-0.90 [95% CI: -1.39 to -0.42]) versus non-OWOB and low MetRisk (referent); factors 5 (branched-chain amino acids), 8 (diacylglycerols), and 9 (steroid hormones) were highest among OWOB and high MetRisk; and factor 7 (long-chain acylcarnitines) was higher among non-OWOB and high MetRisk (0.47 [95% CI: 0.04 to 0.91]) and lower among OWOB and low MetRisk (-0.36 [95% CI: -0.68 to -0.04]).ConclusionsLong-chain fatty acids, branched-chain amino acids, acylcarnitines, diacylglycerols, and steroid hormones differed by weight status and metabolic phenotype.

Project description:We established Project Viva to examine prenatal diet and other factors in relation to maternal and child health. We recruited pregnant women at their initial prenatal visit in eastern Massachusetts between 1999 and 2002. Exclusion criteria included multiple gestation, inability to answer questions in English, gestational age ≥22 weeks at recruitment and plans to move away before delivery. We completed in-person visits with mothers during pregnancy in the late first (median 9.9 weeks of gestation) and second (median 27.9 weeks) trimesters. We saw mothers and children in the hospital during the delivery admission and during infancy (median age 6.3 months), early childhood (median 3.2 years) and mid-childhood (median 7.7 years). We collected information from mothers via interviews and questionnaires, performed anthropometric and neurodevelopmental assessments and collected biosamples. We have collected additional information from medical records and from mailed questionnaires sent annually to mothers between in-person visits and to children beginning at age 9 years. From 2341 eligible women, there were 2128 live births; 1279 mother-child pairs provided data at the mid-childhood visit. Primary study outcomes include pregnancy outcomes, maternal mental and cardiometabolic health and child neurodevelopment, asthma/atopy and obesity/cardiometabolic health.

Project description:BackgroundThe developing kidney is vulnerable to prenatal environmental factors such as metal exposure, potentially altering the risk of later-life kidney dysfunction. This study examines the relationship between prenatal metal exposures, individually and as mixtures, and adolescent kidney function in Project Viva, a prospective longitudinal birth cohort in Massachusetts, USA.MethodsWe used data on metals measured in blood during pregnancy including 15 in the first trimester and four in the second trimester. We calculated estimated glomerular filtration rate (eGFR) in adolescents (mean: 17.7 years) using cystatin C- (eGFRcys) and creatinine-based (eGFRcreat) equations for children. We used linear regression for single metal analyses, and Bayesian kernel machine regression and quantile-based g-computation for mixture analyses, adjusting for relevant covariates. To account for multiple comparisons in the single metal analyses, we applied the Holm-Bonferroni procedure to control the false discovery rate.ResultsThis study included 371 participants with first trimester metals and adolescent eGFR, and 256 with second trimester metals. Each doubling in first trimester cadmium concentration was associated with lower adolescent eGFRcys (β:-1.51; 95% CI:-2.83, -0.18). Each doubling in first trimester chromium (β:-1.45; 95% CI:-2.71, -0.19), nickel (β:-1.91; 95% CI:-3.65, -0.16), and vanadium (β:-1.69; 95% CI:-3.21, -0.17) was associated with lower adolescent eGFRcreat. After adjusting for multiple comparisons, p-values for associations between adolescent eGFR and chromium, nickel, vanadium and cadmium did not meet the criteria for significance. Metal mixture analyses did not identify statistically significant associations with adolescent eGFR.ConclusionsThese findings have important implications for future studies investigating the potential mechanisms through which prenatal metal exposures affect long-term kidney health in children.

Project description:BackgroundAlthough sexual dimorphism in wheeze and asthma prevalence are well documented, sex-specific risk factors for wheeze and longitudinal wheeze phenotypes have not been well elucidated.ObjectiveBy using a large prebirth cohort, this study aimed to identify sex-specific risk factors for wheeze from birth through midchildhood and identify distinct longitudinal wheeze phenotypes and the sex-specific risk factors associated with these phenotypes.MethodsMothers reported child wheeze symptoms over the past year approximately yearly on 9 occasions starting at age 1 year. We identified sex-specific predictors of wheeze, wheeze phenotypes, and sex-specific predictors of these phenotypes by using generalized estimating equations, latent class mixed models, and multinomial logistic analysis, respectively.ResultsA total of 1623 children had information on wheeze at 1 or more time points. Paternal asthma was a stronger predictor of ever wheezing in boys (odds ratio [OR], 2.15; 95% CI, 1.74-2.66) than in girls (OR, 1.53; 95% CI, 1.19-1.96; P for sex by paternal asthma interaction = .03), whereas being black or Hispanic, birth weight for gestational age z score, and breast-feeding duration had stronger associations among girls. We identified 3 longitudinal wheeze phenotypes: never/infrequent wheeze (74.1%), early transient wheeze (12.7%), and persistent wheeze (13.1%). Compared with never/infrequent wheeze, maternal asthma, infant bronchiolitis, and atopic dermatitis were associated with persistent wheeze in both sexes, but paternal asthma was associated with persistent wheeze in boys only (OR, 4.27; 95% CI, 2.33-7.83; P for sex by paternal asthma interaction = .02), whereas being black or Hispanic was a predictor for girls only.ConclusionWe identified sex-specific predictors of wheeze and longitudinal wheeze patterns, which might have important prognostic value and allow for a more personalized approach to wheeze and asthma treatment.

Project description:Physiological regulatory problems in infancy (i.e., problems with sleeping, feeding, and tactile reactivity) have been associated with impairing functional somatic symptoms (FSS) at ages 5-7. We aimed to extend this finding by examining not only the association of physiological regulatory problems but also other infancy factors (i.e., emotion dysregulation and contact problems) with FSS in pre- and late adolescence. Standardized behavioral assessments and self-report questionnaire data from assessment waves at 0-1, 11-12, and 16-17 years of the population-based Copenhagen Child Cohort (CCC2000) were linked with Danish register data on maternal postpartum psychiatric illness and family adversity as covariates. Multiple linear regression analyses were performed to examine the association between infancy factors and FSS in pre- and late adolescence. Only infancy physiological regulatory problems significantly predicted preadolescent FSS (b = 0.38, 95% CI [0.14, 0.62]), also when accounting for maternal postpartum psychiatric illness and family adversity. The association was attenuated for late adolescent FSS.ConclusionInfancy physiological regulatory problems may represent early signs of a dysregulated stress system and were found to significantly predict FSS in pre- but not late adolescence. Implications for early FSS prevention could include testing interventions promoting infants' regulation of sleep, feeding, and tactile reactivity.What is known• Functional somatic symptoms (FSS) are common in adolescence. • Explanatory models of FSS emphasize a multifactorial etiology involving interactions between early child-related vulnerabilities and contextual factors. • Infancy physiological regulatory problems (i.e., problems in the area of sleeping, feeding, and tactile reactivity) might represent early signs of a dysregulated stress system, and have been shown to predict impairing FSS in preschool childhood.What is new• This study investigated the association between infancy factors, namely physiological regulatory problems with feeding, sleeping, and/or tactile reactivity, emotion dysregulation, and contact problems, and FSS in pre- and late adolescence. • Only a combination of infancy physiological regulatory problems significantly predicted preadolescent FSS, with the association attenuating for FSS in late adolescence. • Implications for early FSS prevention could include parent-mediated interventions aiming to promote infants' physiological regulatory skills.

Project description:BackgroundFew prospective data link early childhood adiposity with asthma-related symptoms.ObjectiveWe sought to examine the associations of weight-for-length (WFL) at age 6 months with incidence of wheezing by age 3 years.MethodsWe studied 932 children in a prospective cohort of children. The main outcome was recurrent wheezing, which was defined as parents' report of wheezing between 2 and 3 years of age plus wheezing in either year 1 or 2 of life. Secondary outcomes included any wheezing from 6 months to 3 years and current asthma. We used multiple logistic regression to examine associations of 6-month WFL z scores with these outcomes.ResultsAt 6 months, the infants' mean WFL z score was 0.68 (SD, 0.94; range -2.96 to 3.24). By age 3 years, 14% of children had recurrent wheezing. After adjustment for a variety of potential confounders, we found that each 1-unit increment in 6-month WFL z score was associated with greater odds of recurrent wheezing (odds ratio [OR], 1.46; 95% CI, 1.11-1.91) and any wheezing (OR, 1.23; 95% CI, 1.03-1.48). We observed a weaker association between 6-month WFL z score and current asthma (OR, 1.22; 95% CI, 0.94-1.59).ConclusionInfants with higher WFL z scores at 6 months of age had a greater risk of recurrent wheezing by age 3 years. It is unclear whether the relationship of infant adiposity and early-life wheeze extends to allergic asthma or wheeze that can persist into later childhood. Our findings suggest that early interventions to prevent excess infant adiposity might help reduce children's risk of asthma-related symptoms.

Project description:BackgroundExposure to fine particulate matter (PM with diameter ? 2.5 ?m; PM2.5) has been linked to type 2 diabetes mellitus, but associations with hyperglycemia in pregnancy have not been well studied.MethodsWe studied Boston, Massachusetts-area pregnant women without known diabetes. We identified impaired glucose tolerance (IGT) and gestational diabetes mellitus (GDM) during pregnancy from clinical glucose tolerance tests at median 28.1 weeks gestation. We used residential addresses to estimate second-trimester PM2.5 and black carbon exposure via a central monitoring site and spatiotemporal models. We estimated residential traffic density and roadway proximity as surrogates for exposure to traffic-related air pollution. We performed multinomial logistic regression analyses adjusted for sociodemographic covariates, and used multiple imputation to account for missing data.ResultsOf 2,093 women, 65 (3%) had IGT and 118 (6%) had GDM. Second-trimester spatiotemporal exposures ranged from 8.5 to 15.9 ?g/m3 for PM2.5 and from 0.1 to 1.7 ?g/m3 for black carbon. Traffic density was 0-30,860 vehicles/day × length of road (kilometers) within 100 m; 281 (13%) women lived ? 200 m from a major road. The prevalence of IGT was elevated in the highest (vs. lowest) quartile of exposure to spatiotemporal PM2.5 [odds ratio (OR) = 2.63; 95% CI: 1.15, 6.01] and traffic density (OR = 2.66; 95% CI: 1.24, 5.71). IGT also was positively associated with other exposure measures, although associations were not statistically significant. No pollutant exposures were positively associated with GDM.ConclusionsGreater exposure to PM2.5 and other traffic-related pollutants during pregnancy was associated with IGT but not GDM. Air pollution may contribute to abnormal glycemia in pregnancy.

Project description:BackgroundReligion has rarely been studied as a determinant of infant feeding practices. We examined whether religious affiliation is associated with formula feeding vs breastfeeding intention and practice in women from the United States Project Viva cohort.MethodsBetween 1999 and 2002, 2128 pregnant women were recruited in the area of Boston, Massachusetts. They reported by questionnaire their religious affiliation, and their intended and practiced infant feeding mode (exclusive formula feeding vs partial vs exclusive breastfeeding) at different time points. We examined associations of religious affiliation with infant feeding intention and practice by modified Poisson regression and multinomial logistic regression adjusted for known sociodemographic confounders.ResultsOf 1637 women with complete data, 52% reported being Catholic, 29% Protestant, 11% unaffiliated, 4% Jewish, and 4% other religion. Overall, 8.5% and 15.9% women intended and initiated exclusive formula feeding, respectively. Compared with unaffiliated women, Catholics were more at risk to intend to exclusively formula-feed their infant at birth (risk ratio [95% CI]: 6.4 [1.6-26.0]) and to exclusively formula-feed after delivery (2.4 [1.3-4.2]) and 3 months postpartum (1.3 [0.98-1.8]). The odds ratio for intending and practicing partial (vs exclusive) breastfeeding did not differ by religious affiliation at most examined time points. Associations of Protestant women with infant feeding exhibited estimates closer to unaffiliated than to Catholic women.ConclusionsCatholic women are more at risk to intend and practice exclusive formula feeding than women of other religious affiliations. Our findings may help health care practitioners adapt their breastfeeding promotion to the mother's religious affiliation.

Project description:ObjectiveThis study aimed to examine the associations of two obesity-related metabolite patterns with changes in metabolic biomarkers during early adolescence.MethodsMultivariable linear regression was used to examine associations of branched chain amino acid (BCAA) and androgen hormone patterns with changes in glycemia (fasting glucose, insulin, homeostatic model assessment of insulin resistance), adipokines (leptin, adiponectin), inflammation (C-reactive protein, interleukin-6), lipid profile, and blood pressure during ∼5 years of follow-up among 213 children aged 6 to 10 years at baseline. Covariates included baseline age, pubertal status, biomarker level, and BMI percentile, and age at follow-up. Interactions with sex and baseline BMI percentile were also considered.ResultsThe median age at baseline was 7.7 years; 48.8% were boys. In adjusted models, each 1 unit of the BCAA pattern corresponded with a 4.82 (95% CI: 0.92 to 8.71) mg/dL decrease in fasting glucose in boys. In girls, the BCAA pattern was associated with an increase in triglycerides (4.17 [0.03 to 8.32] mg/dL). The androgen pattern was associated with decreased leptin (-2.35 [-4.34 to -0.35] ng/dL) and increased C-reactive protein (0.28 [0.03 to 0.54] mg/dL) in girls. These relationships did not differ by baseline BMI percentile.ConclusionsThe BCAA and androgen hormone metabolite patterns are related to changes in metabolic parameters in a sex-specific manner during early adolescence.
