Abstract
Mental health research is still relatively neglected and highly difficult in the Arab world. ADHD is the most common neurodevelopmental pediatric disorder. Our work was a population-based epidemiologic study of ADHD not a clinic-referred research. It was conducted on a representative sample of school children (ages: 4 to 12 years) in Minia city, Minia Governorate to determine the prevalence of ADHD.
Study groups in our study included: Children with ADHD (70 children) who fulfilled all diagnostic criteria and required investigations and a control group (25 children) with matched age and sex, average intelligence (IQ≥90) and normal attention. Results revealed; the overall prevalence of ADHD was 6.5% and the prevalence rates of different subtypes in order of frequency were; hyperactive impulsive type (3.51%), then combined type (2.13%), and lastly inattentive type (0.86%). The prevalence in males was (4.01%), while in females (2.48%). Male to female ratio was 1.61:1. The prevalence of males was higher than in females regarding the hyperactive-impulsive and combined types, while the reverse was in the inattentive type.
A variety of socioeconomic factors were significantly associated with the development of ADHD. These included low socioeconomic status (P-value < 0.001), scholastic achievement (P-value < 0.001), first birth order (P<0.04), large family size (P<0.03) and bottle feeding (P<0.01). Children with ADHD had higher abnormal EEG findings, low HB%. There were significant differences between cases and control groups regarding some co morbid disorders as secondary nocturnal enuresis (p = 0.02), delayed developmental milestones (p = 0.04) and disruptive behaviors (p = 0.02).
Insignificant differences between cases and control groups were present regarding: Age, gestational age, IQ scores, total leucocytic count, platelet count and random blood sugar and some comorbid disorders eating disorders and sleep disorders.
We have been faced by many obstacles in our research. The majority of our results were to some extent matched with the literature of ADHD while some results weren’t the same which may be attributed to cultural characteristics and sociodemographic issues. Further research is needed in our community on the etiology, associated genetics, biological, and culture-specific risk factors, prevention and treatment.
