To determine the association between longitudinal growth measures (height, weight, head circumference, and extent of catch-up growth) and neuropsychological functioning at 7 years in moderately and late preterm children.This study was part of a prospective, community-based cohort study. Data on growth were obtained from records on routine assessments in well-child centers until age 4 years and in a research setting at 7 years. Neuropsychological functioning was assessed at age 7 years. We assessed associations of growth with neuropsychological functioning and determined odds ratios for impaired neuropsychological functioning. All analyses were corrected for maternal education.We included 234 children. Median gestational age was 34 weeks (P25-75: 33-35 weeks), and mean birth weight was 2.2 kg ( 0.5 kg). Short stature at all ages was associated with poorer motor, IQ, and attention scores and led to increased risks of impaired motor skills and low IQ. Lower weight at 1 and 4 years was associated with poorer IQ scores. Increased weight gain between age 4 and 7 years was, however, associated with poorer motor, IQ, and attention scores. Decreased head circumference gain in the first year of life was associated with poorer motor and attention scores and led to an increased risk of impaired motor and attention skills.In moderately and late preterm children, poorer growth in the first 7 years is associated with poorer neuropsychological functioning. Regarding height, short stature was also associated with a higher likelihood of clinically relevant impaired neuropsychological functioning.

Patterns of longitudinal lung function growth and decline in childhood asthma have been shown to be important in determining risk for future respiratory ailments including chronic airway obstruction and chronic obstructive pulmonary disease.To determine the genetic underpinnings of lung function patterns in subjects with childhood asthma.We performed a genome-wide association study of 581 non-Hispanic white individuals with asthma that were previously classified by patterns of lung function growth and decline (normal growth, normal growth with early decline, reduced growth, and reduced growth with early decline). The strongest association was also measured in two additional cohorts: a small asthma cohort and a large chronic obstructive pulmonary disease metaanalysis cohort. Interaction between the genomic region encompassing the most strongly associated single-nucleotide polymorphism and nearby genes was assessed by two chromosome conformation capture assays.An intergenic single-nucleotide polymorphism (rs4445257) on chromosome 8 was strongly associated with the normal growth with early decline pattern compared with all other pattern groups (P=6.710Early decline in lung function after normal growth is associated with a genetic polymorphism that may also protect against early decline in reduced growth groups. Clinical trial registered with www.clinicaltrials.gov (NCT00000575).
