Child Opportunity Index Mobility, Recurrent Wheezing, and Asthma in Early Childhood: A Population-Based Prospective Cohort Study.

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.

Place-Based Child Opportunity at Birth and Child Development from Infancy to Age 4.

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.

Longitudinal Child Growth Patterns in Twins and Singletons in the Upstate KIDS Cohort.

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.

Age of Juice Introduction and Child Anthropometry at 2-3 and 7-9 Years.

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.

Feeding Problems as an Indicator of Developmental Delay in Early Childhood.

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.

Parental Weight Status and Offspring Behavioral Problems and Psychiatric Symptoms.

OBJECTIVES: To assess relations of prepregnancy maternal and paternal obesity with offspring behavioral problems and psychiatric symptoms at 7-8 years in the Upstate KIDS study, a prospective cohort study. STUDY DESIGN: Maternal body mass index (BMI) was calculated from prepregnancy height and weight provided in vital records or self-report at 4 months postpartum. Mothers reported paternal height and weight. At 7-8 years, mothers indicated if their children had been diagnosed with ADHD or anxiety (n = 1915). Additionally, children's behavior was measured with the Strengths and Difficulties Questionnaire at 7 years of age (n = 1386) and the Vanderbilt ADHD Diagnostic Parent Rating Scale at 8 years of age (n = 1484). Based on Strengths and Difficulties Questionnaire scores, we identified children with borderline behavioral problems. Adjusted risk ratios (aRR) and 95% CIs were estimated with robust multivariable Poisson regression. RESULTS: Compared with children of mothers with a BMI of <25, children whose mothers had BMI 25-30, 30-35, and ≥35 kg/m2 had higher risks of reported ADHD (aRR, 1.14, 95% CI, 0.78-1.69; aRR, 1.96, 95% CI, 1.29-2.98; and aRR, 1.82, 95% CI,1.21-2.74, respectively). Risks of hyperactivity problems identified by the Strengths and Difficulties Questionnaire and a positive screen for inattentive or hyperactive/impulsive behavior with the Vanderbilt ADHD Diagnostic Parent Rating Scale were also higher with increasing maternal prepregnancy BMI. Paternal BMI was not associated with child outcomes. CONCLUSIONS: Our findings suggest that maternal, rather than paternal, obesity is associated with maternal report of child ADHD diagnosis and inattentive or hyperactivity problems. Further research is needed to understand how maternal obesity might influence these behavioral changes during or after pregnancy.

Assessing the health of migrant and seasonal farmworkers in New York State: statewide data 2003-2005.

OBJECTIVES: New York State data were used to document demographic characteristics and identify the top five most prevalent disease conditions among migrant and seasonal farmworkers and their families working in the state from 2003 to 2005. METHODS: Prevalence estimates were derived using enumeration and diagnosis data provided by New York State Department of Health contractors. The sample totals ranged from 6,500 to 8,000 migrant and seasonal farmworkers and their families. RESULTS: The majority of migrant and seasonal farmworkers were Hispanic with New York or Mexico the most frequently reported migrant home. Infections, muscular skeletal problems, respiratory disease, hypertension, and diabetes were the five most prevalent diseases identified. CONCLUSION: Migrant and seasonal farmworkers in New York State experienced health conditions common among agricultural workers. Additional research and surveillance are necessary for understanding and serving their health needs.
