Abstract

OBJECTIVE:

Children with very low birth weight (<1500 g) are at increased risk for attention deficit hyperactivity disorder (ADHD). Whether this increased risk continues into adulthood is unknown. The authors assessed behavioral symptoms of ADHD in a well-characterized cohort of very-low-birth-weight young adults who were either small for gestational age (less than two standard deviations below the Finnish mean) or appropriate for gestational age (within two standard deviations of the mean).

METHOD:

A total of 162 very-low-birth-weight subjects (small for gestational age: N=52; appropriate for gestational age: N=110) and 172 term comparison subjects 18 to 27 years of age completed the Adult Problem Questionnaire, which yielded six exploratory factor analysis-derived subscales. Participants were also asked about substance use.

RESULTS:

Very-low-birth-weight adults in the small for gestational age subgroup scored higher on the executive dysfunctioning and emotional instability subscales of the Adult Problem Questionnaire than did those in the appropriate for gestational age subgroup and the comparison group. The appropriate for gestational age and comparison groups had similar scores on these subscales. On the alcohol use subscale of the Adult Problem Questionnaire, both the appropriate and small for gestational age subgroups scored lower than comparison subjects and also reported fewer risk-taking behaviors (alcohol, smoking, and use of recreational drugs) than did comparison subjects.

CONCLUSIONS:

Rather than very low birth weight per se, intrauterine growth retardation, as reflected by small for gestational age status in the very-low-birth-weight subjects, confers a risk for behavioral and emotional adversity related to ADHD in young adulthood.
