Abstract

Objective: The objective of the present study was to find the prevalence of attention deficit hyperactivity (ADH) symptoms in a sample of primary schoolchildren in Qatar and investigate the behaviour of the children with and without ADH symptoms in a highly consanguineous community. Subjects and Methods: A total of 2,500 primary school students, aged 6-12 years, were randomly selected from the government primary schools, and 1,869 students ( 947 boys and 922 girls) gave consent to participate in this study. An Arabic questionnaire was used to collect the sociodemographic variables and a standardized Arabic version of the Conners' Teacher Rating Scale for ADH symptoms. Results: Of the 947 boys, 158 (16.7%; 95% confidence interval, CI, 14.4-19.2) and of the 922 girls, 50 ( 5.4%; 95% CI 4.1-7.1) scored above the cut-off (>= 15) for ADH symptoms, thus giving an overall prevalence of 11.1% ( 95% CI 9.7-12.6). The children who had higher scores for ADH symptoms were in the age group of 6-9 years. Children who had higher scores for ADH symptoms had a poorer school performance than those with lower scores ( p = 0.002). Two hundred ( 96.2%) children with ADH were disobedient, 126 (60.6%) noisy and hyperactive, 76 (36.5%) very cranky, 78 (37.5%) troublesome and 79 (37.9%) nervous. The logistic regression identified socio-economic condition, number of children, school performance and poor relationship between parents as the main contributors to ADH. Although the univariate analysis showed a significant relationship ( p = 0.010) between ADH symptoms and consanguineous parents, logistic regression did not support this association ( p = 0.075). This suggests that consanguinity has no impact on ADH children. Conclusion: The study revealed that ADH is a common problem among schoolchildren. The children with higher scores for ADH symptoms had a poorer school performance than those with lower scores. A significant difference exists between the behaviour of children with and without ADH.
