Abstract
Objective:
We aimed to investigate the relation between birth order, number of siblings, and prevalence of Attention Defi cit Hyperactivity Disorder (ADHD), among children brought to the world via vaginal delivery.
Method:
Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Version-Turkish Version (K-SADSPL- T) was applied to 66 children with ADHD and 77 healthy children, and Turgay Child and Adolescent Disruptive Behavioral Disorders Screening and Rating Scale, that was derived from DSM-IV ADHD criteria and sociodemographic data form for all participants were completed by the parents of all children.
Results:
Forty three (65.2%) of ADHD children were fi rst borns in their families, 20 (30.3%) were the second, 2 (3%) were the third, and 1 (1.5%) was the fourth child. In the control group 48 (62.3%) were the fi rst, 24 (31.2%) were second, and 5 (6.5%) were third children of their families. No difference between groups was found regarding order of birth. Likewise, there was no difference between groups in terms of gender and Turgay Child and Adolescent Disruptive Behavioral Disorders Screening and Rating Scale scores. The number of siblings correlated with hyperactivity-impulsivity subscale scores, in ADHD group.
Discussion:
‘The number of siblings was negatively correlated with hyperactivity-impulsivity subscale scores in ADHD group.’
