Evaluation of the Relative Frequency of Attention Deficit Hyperactivity Disorder (ADHD) in 6-Year-Old Children with Low Birth Weight in Yazd

ADHD (attention deficit hyperactivity disorder) is a neuro-behavioral syndrome that is characterized by a lack of attention, irritability, high activity, distressed behaviors, especially in boys. A cohort study was conducted on 120 children aged 6 years. 60 children with low birth weight (less than 2500 g) as exposed group and 60 children with birth weight more than 3000 g as non-cohort Exposure to information collection was collected through a questionnaire distributed to families. At the end of the study, the relative frequency of hyperactivity and attention deficit disorders in low birth weight children was investigated The relative frequency of composite ADHD in the exposed group was 26/7% and in the non-exposed group was 18/3% (P-value: 0/274). The mean ADHD of the compound type in the exposure group was 5/060 and in the non-exposed group was 3/400 (P value: 0/033). In this study, the relative frequency of composite ADHD in terms of sex, feeding during infancy and birth was considered. The results showed that the p value was not significantly different, but probably not due to the quantitative size of the sample. Relative frequency of composite ADHD in children with low birth weight was 26/7%, but this level was not statistically significant, ie, ADHD is not associated with low birth weight. But in terms of medicine, this relative frequency is almost 1/5 times higher than the non-exposed group.
