Low weight, socioeconomics and behavioral issues: examining a population in the Northeast of Brazil.

Background: Preterm and low weight children at birth are exposed to higher risks and rates of motor, cognitive, behavioral and emotional problems. Being born under low socioeconomic conditions adds even more complexity to these children. This report describes the emotional and behavioral issues of a group of children who were born in low income families and had low weigh at birth in the Northeast region of Brazil.

Method: A total of 100 children (47 with adequate and 53 with low weigh) were assessed with the Child Behavior Checklist for behavioral and emotional problems, as well as with the Autism Behavior Checklist for autism symptoms.

Results: Results show no difference between the two groups (low and adequate weight) in terms of behavior problems or autism characteristics, however, it shows elevated clinical prevalence's of behavioral and emotional problems and more vulnerability for autism symptoms when compared to the general population. Data also showed the more years children spent in pre-school, the less internalizing problems they manifested.

Conclusion: This study indicates that the impact of low socioeconomics environment is more prominent in the development of behavioral and emotional problems than low weight at birth, in addition it points to the benefits of pre-school years for the emotional and behavioral adjustment of children from low income and with low weight at birth.
