Association between birth weight and neurodevelopment at age 1-6 months: results from the Wuhan Healthy Baby Cohort.

ABSTRACT:

Objective

The association between birth weight and infants' neurodevelopment is not well understood. We aimed to examine the impact of birth weight on neurodevelopment of infants at age 1-6 months using data from the Wuhan Healthy Baby Cohort (WHBC) study.

Setting and participants

This is a prospective cohort study of 4026 infants from the WHBC study who were born at the Women and Children's Hospital of Wuhan, China between October 2012 and September 2013 and who had complete healthcare records within 6 months after birth. Participants were categorised into three groups according to their birth weight: low birth weight (LBW; birth weight <2500?g), normal birth weight (2500 g ? birth weight <4000?g) and macrosomia (birth weight ?4000?g).

Main outcome measures

The main outcomes were development quotient (DQ) and clinical diagnosis of neurodevelopmental delay. Both adjusted regression coefficients and ORs were estimated for LBW and macrosomia.

Results

Of the 4026 infants, 166 (4.12%) were of LBW and 237 (5.89%) were with macrosomia. Adjusted regression coefficients of LBW and macrosomia for gross motor DQ were -11.18 (95% CI -11.36 to 10.99) and 0.49 (95% CI 0.36 to 0.63), fine motor DQ -6.57 (95% CI -6.76 to -6.39) and -2.73 (95% CI -2.87 to -2.59), adaptability DQ -4.87 (95% CI -5.05 to -4.68) and -1.19 (95% CI -1.33 to -1.05), language DQ -6.23 (95% CI -6.42 to -6.05) and 0.43 (95% CI 0.29 to 0.57), and social behaviour DQ -6.82 (95% CI -7.01 to -6.64) and 1.10 (95% CI 0.96 to 1.24). Adjusted OR of LBW for clinical diagnosis of 'neurodevelopmental delay' in gross motor was 2.43 (95% CI 1.65 to 3.60), fine motor 1.49 (95% CI 1.01 to 2.19) and adaptability 1.56 (95% CI 1.06 to 2.31). LBW has no significant effects on 'neurodevelopmental delay' in language and social behaviour, and macrosomia has no significant effects on clinical diagnosis of 'neurodevelopmental delay' in all domains.

Conclusion

Both LBW and macrosomia are associated with infants' DQ, and LBW increases the risk of being diagnosed with 'neurodevelopmental delay' in gross motor, fine motor and adaptability among infants aged 1-6 months.

Project description:BackgroundIn utero exposure to Zika virus (ZIKV) is known to be associated with birth defects. The impact of in utero ZIKV exposure on neurodevelopmental outcomes in early childhood remains unclear. The objective of this study was to determine the impact of in utero ZIKV exposure on neurodevelopment at 24?months of age among toddlers who were born normocephalic to women who were pregnant during the 2016 ZIKV outbreak in French territories in the Americas.MethodsWe conducted a population-based mother-child cohort study of women whose pregnancies overlapped with the 2016 ZIKV epidemic in Guadeloupe, Martinique, and French Guiana. Infants were included in this analysis if maternal ZIKV infection during pregnancy could be determined, the newborn had a gestational age ? 35?weeks, there were no abnormal transfontanelle cerebral ultrasound findings after delivery or no abnormal ultrasound findings on the last ultrasound performed during the third trimester of the mother's pregnancy, there was an absence of microcephaly at birth, and the parent completed the 24-month neurodevelopment assessment of the infant at 24?months (±?1?month) of age. ZIKV exposure of the toddler was determined by evidence of maternal ZIKV infection during pregnancy. Neurodevelopment assessments included the Ages and Stages Questionnaire (ASQ) for five dimensions of general development-communication, gross motor, fine motor, problem solving, and personal-social skills; the Modified Checklist for Autism on Toddlers (M-CHAT) for behavior; and the French MacArthur Inventory Scales (IFDC) for French language acquisition.ResultsBetween June 2018 and August 2019, 156 toddlers with and 79 toddlers without in utero ZIKV exposure completed neurodevelopment assessments. Twenty-four (15.4%) ZIKV-exposed toddlers and 20 (25.3%) ZIKV-unexposed toddlers had an ASQ result below the reference -?2SD cut-off (P?=?0.10) for at least one of the five ASQ dimensions.ConclusionIn one of the largest population-based cohorts of in utero ZIKV-exposed, normocephalic newborns to date, there were minimal differences apparent in neurodevelopment outcomes at 24?months of age compared to ZIKV-unexposed toddlers at 24?months of age.Trial registrationClinicalTrials.gov, NCT02810210 .

Project description:ObjectivePostnatal steroid use decreases lung inflammation but increases impairment. We hypothesized that increased dose is associated with increased neurodevelopmental impairment, lower postmenstrual age at exposure increases impairment, and risk of bronchopulmonary dysplasia modifies the effect of postnatal corticosteroid.MethodsSteroid dose and timing of exposure beyond 7 days was assessed among 2358 extremely low birth weight infants nested in a prospective trial, with 1667 (84%) survivors examined at 18 to 22 months' postmenstrual age. Logistic regression tested the relationship between impairment (Bayley Mental Developmental Index/Psychomotor Developmental Index of <70, disabling cerebral palsy, or sensory impairment), total dose (tertiles: <0.9, 0.9-1.9, and >/=1.9 mg/kg), and postmenstrual age at first dose. Separate logistic regression tested effect modification according to bronchopulmonary dysplasia severity (Romagnoli risk > 0.5 as high risk, n = 2336 (99%) for days of life 4-7).ResultsThree hundred sixty-six (16%) neonates were steroid-treated (94% dexamethasone). Treated neonates were smaller and less mature; 72% of those treated were at high risk for bronchopulmonary dysplasia. Exposure was associated with neurodevelopmental impairment/death. Impairment increased with higher dose; 71% dead or impaired at highest dose tertile. Each 1 mg/kg dose was associated with a 2.0-point reduction on the Mental Developmental Index and a 40% risk increase for disabling cerebral palsy. Older age did not mitigate the harm. Treatment after 33 weeks' postmenstrual age was associated with greatest harm despite not receiving the highest dose. The relationship between steroid exposure and impairment was modified by the bronchopulmonary dysplasia risk, with those at highest risk experiencing less harm.ConclusionsHigher steroid dose was associated with increased neurodevelopmental impairment. There is no "safe" window for steroid use in extremely low birth weight infants. Neonates with low bronchopulmonary dysplasia risk should not be exposed. A randomized trial of steroid use in infants at highest risk is warranted.

Project description:Introduction:Understanding which foods are introduced in the diet and when provides valuable information on complementary feeding. Fortified baby rice cereal is the most common first solid food given to infants, often followed by other baby cereals. The objective of this study was to examine food patterns among infants and toddlers consuming rice or non-rice baby cereals versus non-consumers. Methods:NHANES 2001-2014 data were used to assess dietary intake, nutrient adequacy, and food specific patterns of infants and toddlers. Groups were: baby cereal non-consumers (n = 3,910), non-rice baby cereal consumers (n = 711), and rice baby cereal consumers (n = 966). Those consuming both non-rice cereal and rice cereal were included in the rice cereal group (n = 9, 48, 61, and 10 for those 0-3, 4-6, 7-11, and 12-23 mos, respectively). Least-square means ± SEs were determined for nutrient intake and food group consumption by using covariate controlled regression analyses (p < 0.01). Results:Baby cereal consumer groups, compared to non-consumers, had higher intakes of carbohydrates, iron, calcium, magnesium, zinc, and vitamin E, with lower percentage having intakes below the Estimated Average Requirement for iron, calcium, and vitamin E. Infants 0-3 mos and 4-6 mos in both baby cereal consumption groups consumed other solid foods, including baby foods and beverages, sweetened beverages, coffee and tea, 100% juice, vegetables (excluding potatoes), fruit, sugars, milk and yogurt, and mixed dishes. The baby cereal consumers and non-consumers groups had intakes aligned with the "American diet". Baby cereal non-consumers had a significantly higher percentage of exclusively breast fed at ages 0-3 mos and a lower percentage formula fed. Conclusion:This study provides detailed information on the introduction of baby cereals which was associated with better nutrient intakes and other complementary foods and intakes of nutrients that require special attention during early life. Further, cow's milk products and solid foods were introduced prior to the American Academy of Pediatrics' age recommendations.
