OBJECTIVE. The goal was to examine the associations of weight-for-length at birth and 6 months with obesity 3 years age. METHODS. We studied 559 children in Project Viva, an ongoing, prospective, cohort study pregnant women their children. measured length weight birth, months, years. Our main exposures were z score adjusted for gestational age birth. used multivariate regression analyses predict independent effects and, separately, 6-month on BMI score, sum subscapular triceps skinfold...

OBJECTIVE: To identify sensitive periods of postnatal growth for preterm infants relative to neurodevelopment at 18 months' corrected age. PATIENTS AND METHODS: We studied 613 born <33 weeks' gestation who participated in the DHA Improvement Neurodevelopmental Outcome trial. calculated linear slopes weight, length, BMI, and head circumference from 1 week age term (40 postmenstrual age), 4 months, 12 we estimated their associations with Bayley Scales Infant Development, 2nd Edition,...

The authors investigated the rate of gestational weight gain associated with lowest combined risk 5 short- and longer-term maternal child health outcomes for 2,012 mother-child pairs recruited in 1999–2002 into Project Viva, a prebirth cohort study Massachusetts. Within each prepregnancy body mass index (BMI, kg/m2) stratum, they performed logistic regression analysis predicting all outcomes, from which determined at average predicted prevalence adverse was lowest. mean total 0.39 kg/week...

The incidence of mother-to-newborn SARS-CoV-2 transmission appears low and may be associated with biological social factors. However, data are limited on the factors neonatal clinical or viral testing outcomes.To ascertain percentage neonates who were born to mothers positive test results during birth hospitalization, sociodemographic result positivity, virological outcomes for newborns hospitalization 30 days after discharge.This multicenter cohort study included 11 academic community...

To provide an updated birth weight-for-gestational age (BW-for-GA) reference in the United States by using most recent, nationally representative data with obstetric estimates of gestational (GA).We abstracted 3 285 552 singleton births between 22 and 42 weeks' gestation nonmissing race and/or ethnicity, infant sex, parity, weight, estimate GA from 2017 US natality files. We used 2 techniques (nonlinear, resistant smoothing [4253H] lambda-mu-sigma) to derive smoothed BW-for-GA curves...

Abstract Background It is not known whether SARS-CoV-2 can be transmitted from mother to infant during breastfeeding, and if so the benefits of breastfeeding outweigh this risk. This study was designed evaluate 1) RNA detected in milk on breast infected women, 2) concentrations milk-borne anti-SARS-CoV-2 antibodies, 3) capacity neutralize infectivity. Methods We collected 37 samples 70 swabs (before after washing) 18 women recently diagnosed with COVID-19. Samples were analyzed for using...

In recent years, the prevalence of hypertension and prehypertension increased markedly among children adolescents, highlighting importance identifying determinants elevated blood pressure early in life. Low birth weight rapid childhood gain are associated with higher future pressure. However, few studies have examined timing postnatal relation to later pressure, little is known regarding contribution linear growth. We studied 957 participants Project Viva, an ongoing US prebirth cohort....
