RESUMO
We prospectively examined associations between mobility in neighborhood opportunity and early childhood recurrent wheezing/asthma. Downward mobility was associated with developing asthma, but not recurrent wheezing, though associations were attenuated after adjusting for family-level socioeconomic status. Elucidating how neighborhoods impact asthma may inform asthma equity initiatives in early childhood.

OBJECTIVE: The objective of this study was to evaluate whether the children's neighborhood quality, as a measure of place-based social determinants of health, is associated with the odds of developmental delay and developmental performance up to the age of 4 years. STUDY DESIGN: Mothers of 5702 children from the Upstate KIDS Study, a longitudinal population-based cohort of children born from 2008 through 2010, provided questionnaire data and a subset of 573 children participated in a clinic visit. The Child Opportunity Index 2.0 was linked to home census tract at birth. Probable developmental delays were assessed by the Ages and Stages Questionnaire up to 7 times between 4 and 36 months, and developmental performance was assessed via the Battelle Developmental Inventory at the age of 4 years. RESULTS: In unadjusted models, higher neighborhood opportunity was protective against developmental delays and was associated with slightly higher development scores at age 4. After adjusting for family-level confounding variables, 10-point higher Child Opportunity Index (on a 100-point scale) remained associated with a lower odds of any developmental delay (OR = .966, 95% CI = .940-.992), and specifically delays in the personal-social domain (OR = .921, 95% CI = .886-.958), as well as better development performance in motor (B = 0.79, 95% CI = 0.11-1.48), personal-social (B = 0.64, 95% CI = 0.003-1.28), and adaptive (B = 0.69, 95% CI = 0.04-1.34) domains at age 4. CONCLUSIONS: Community-level opportunities are associated with some aspects of child development prior to school entry. Pediatric providers may find it helpful to use neighborhood quality as an indicator to inform targeted developmental screening.

OBJECTIVES: To investigate childhood growth patterns in twins and to determine whether they show the same signs of excess growth as singletons born small-for-gestational age (SGA), which may confer future cardiometabolic risk. STUDY DESIGN: In the Upstate KIDS cohort of infants delivered from 2008 through 2010, we compared height, weight, and body mass index (BMI) z-scores at 0-3 and 7-9 years of age, as well as risk of rapid weight gain (RWG) in infancy and overweight/obesity beginning at 2 years, among appropriate-for-gestational age (AGA) twins (n = 1121), AGA singletons (n = 2684), and two groups of SGA twins: uncertain SGA twins (<10th percentile for birthweight by a singleton reference but >10th% by a population-based twin birthweight reference; n = 319) and true SGA twins (<10th% by a population-based twin reference; n = 144). RESULTS: Compared with AGA twins, both SGA twin groups had lower weight and BMI z-scores at both time points. By 7-9 years, both groups caught up in height with AGA twins. Compared with AGA singletons, z-score differences decreased between 0-3 and 7-9 years for uncertain SGA and true SGA twins, though true SGA twins had the lowest z-scores for all measures. During infancy, twins were more likely to display RWG compared with AGA singletons (RR = 2.06 to 2.67), which may reflect normal catch-up growth, as no twin group had higher prevalence of overweight/obesity at either time point. CONCLUSIONS: Though twins had lower height, weight, and BMI z-scores at birth and into toddlerhood, differences were reduced by 7-9 years, with no evidence of pathological growth and no group of twins showing elevated risk of overweight/obesity.

OBJECTIVES: To assess the association between age of juice introduction and child anthropometry after the American Academy of Pediatrics changed their guidelines in 2017 to recommend delaying juice introduction until at least 12 months of age (previously 6 months), citing concerns of weight gain. STUDY DESIGN: Upstate KIDS is a prospective birth cohort with follow-up through 9 years of age. Juice introduction was assessed on parental questionnaires at 4-18 months and categorized as <6, 6-<12, and ≥12 months. Child height and weight were recorded at 2-3 and 7-9 years of age. Weight-, height-, and body mass index (BMI)-for-age and sex z scores were calculated using the Centers for Disease Control and Prevention reference. Overweight/obese and obese status were categorized as BMI-for-age z score ≥85th and ≥95th percentiles. Controlling for sociodemographic characteristics and parental BMI, we assessed the associations of age of juice introduction with child anthropometry. RESULTS: Prevalence of childhood obesity was 16.4% at 2-3 (n = 1713) and 22.8% at 7-9 years of age (n = 1283). Juice introduction at <6 vs ≥12 months was associated with higher weight-for-age z score at 2-3 years of age (mean difference = 0.21; 95% CI 0.04-0.37). At 7-9 years of age, juice introduction at <6 vs ≥12 months was related to higher BMI-for-age (0.38; 0.12-0.64) and weight-for-age z scores (0.27; 0.06-0.49). Risk of developing overweight/obesity and obesity was 1.54 (0.99-2.38) and 2.17 (1.11-4.23) times higher among children with juice introduced at <6 months. No associations were found with juice introduced at 6-<12 vs ≥12 months. CONCLUSIONS: Risk of developing overweight/obesity or obesity is higher among children introduced to juice before 6 months of age compared with ≥12 months.

OBJECTIVE: To determine whether feeding problems are indicators of developmental delay. STUDY DESIGN: In this prospective longitudinal cohort study, mothers of 3597 children (49% female, 35% multiples) reported on their children's feeding problems and developmental delays (using the Ages and Stages Questionnaire [ASQ]) when children were age 18, 24, and 30 months. Average scores of feeding problems were computed at each age, as well as a categorical score indicating a persistently high number of feeding problems ≥90th percentile across time. The Battelle Developmental Inventory, Second Edition (BDI-2) was used to assess development in 5 domains for a subset of children at 4 years. RESULTS: In adjusted analyses, feeding problems (per point increase) were increasingly associated with 6 ASQ domains from 18 months (OR, 1.30-1.98) to 24 months (OR, 2.07-2.69) to 30 months (OR, 3.90-5.64). Compared with children who never experienced feeding problems, children who experienced a high number of feeding problems at 1 or 2 time points were more than twice as likely to have a delay on all ASQ domains (OR, 2.10-2.50), and children who experienced a high number of feeding problems at all 3 time points were ≥4-fold more likely to have a delay on all ASQ domains (OR, 3.94-5.05). Children with 1-point higher feeding problems at 30 months scored 3-4 points lower in all BDI-2 domains at 4 years. CONCLUSIONS: Frequent feeding problems, especially those that persist into the third year, could be used to identify children at risk for developmental delay for more targeted screening.

In a cross-society comparison, we assessed the state of mothers' knowledge of child rearing and child development. The study included 1,077 mothers from five countries on four continents: Argentina, Belgium, Italy, South Korea, and the United States. A criteria-referenced instrument, the Knowledge of Infant Development Inventory, was used to assess parenting knowledge after being adapted for cross-society comparison using item response theory and the alignment optimization approach for testing between-sample measurement invariance. Levels of mothers' parenting knowledge varied across the five societies and were associated with different sociodemographic factors and personal and non-personal supports.
RESUMO
OBJECTIVE: To investigate whether children born very preterm, moderate-late preterm, and term differ in their average level and individual-difference stability in language performance over time. STUDY DESIGN: Language was assessed at 5 and 20 months and 4, 6, and 8 years of age in 204 very preterm (<32 weeks' gestation), 276 moderate-late preterm (32-36 weeks' gestation), and 268 term (37-41 weeks' gestation) children from the Bavarian Longitudinal Study. RESULTS: Very preterm children consistently performed worse than term-born children, and moderate-late preterm children scored in between. Language performance was stable from 5 months through 8 years in all gestation groups combined, and stability increased between each succeeding wave. Stability was stronger between 5 months and 4 years in very preterm than moderate-late preterm and term groups, but this differential stability attenuated when covariates (child nonverbal intelligence and family socioeconomic status) were controlled. CONCLUSIONS: Preterm children, even moderate-late preterm, are at risk for poorer language performance than term-born children. Because individual differences in language performance are increasingly stable from 20 months to 8 years in all gestation groups, pediatricians who attend to preterm children and observe language delays should refer them to language intervention at the earliest age seen.

Mother-infant vocal interactions serve multiple functions in child development, but it remains unclear whether key features of these interactions are community-common or community-specific. We examined rates, interrelations, and contingencies of vocal interactions in 684 mothers and their 5½-month-old infants in diverse communities in 11 countries (Argentina, Belgium, Brazil, Cameroon, France, Israel, Italy, Japan, Kenya, South Korea, and the United States). Rates of mothers' and infants' vocalizations varied widely across communities and were uncorrelated. However, collapsing the data across communities, we found that mothers' vocalizations to infants were contingent on the offset of the infants' nondistress vocalizing, infants' vocalizations were contingent on the offset of their mothers' vocalizing, and maternal and infant contingencies were significantly correlated. These findings point to the beginnings of dyadic conversational turn taking. Despite broad differences in the overall talkativeness of mothers and infants, maternal and infant contingent vocal responsiveness is found across communities, supporting essential functions of turn taking in early-childhood socialization.

BACKGROUND: It is generally believed that parental rejection of children leads to child maladaptation. However, the specific effects of perceived parental acceptance-rejection on diverse domains of child adjustment and development have been incompletely documented, and whether these effects hold across diverse populations and for mothers and fathers are still open questions. METHODS: This study assessed children's perceptions of mother and father acceptance-rejection in 1,247 families from China, Colombia, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand, and the United States as antecedent predictors of later internalizing and externalizing behavior problems, school performance, prosocial behavior, and social competence. RESULTS: Higher perceived parental rejection predicted increases in internalizing and externalizing behavior problems and decreases in school performance and prosocial behavior across 3 years controlling for within-wave relations, stability across waves, and parental age, education, and social desirability bias. Patterns of relations were similar across mothers and fathers and, with a few exceptions, all nine countries. CONCLUSIONS: Children's perceptions of maternal and paternal acceptance-rejection have small but nearly universal effects on multiple aspects of their adjustment and development regardless of the family's country of origin.

We assessed 2 forms of agreement between mothers' and fathers' socially desirable responding in China, Colombia, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand and the United States (N = 1110 families). Mothers and fathers in all 9 countries reported socially desirable responding in the upper half of the distribution, and countries varied minimally (but China was higher than the cross-country grand mean and Sweden lower). Mothers and fathers did not differ in reported levels of socially desirable responding, and mothers' and fathers' socially desirable responding were largely uncorrelated. With one exception, mothers' and fathers' socially desirable responding were similarly correlated with self-perceptions of parenting, and correlations varied somewhat across countries. These findings are set in a discussion of socially desirable responding, cultural psychology and family systems.
