Abstract

OBJECTIVES
The aims of this study were to examine the prevalence of Attention Deficit Hyperactivity Disorder(ADHD) as well as the relationship between ADHD and related factors among elementary school students living nearby Shihwa-Banwol industrial complex.
METHODS
A cross-sectional survey was conducted on 573 elementary students living nearby Shihwa-Banwol industrial complex. Dupaul ADHD rating scales were used for assessment of ADHD. Information on age, gender, birth weight, family history, environmental factors including second-hand smoke, house income, house type, bring up a child, road proximity and behavioral factors including outside activity time, eating habits, and cell phone usage were based on data from self-administered questionnaires. Multiple logistic regression analysis was performed, and all odds ratios were adjusted according to age and gender.
RESULTS
The prevalence of ADHD was 9.4%, and those aged 10 years were the most affected. Male elementary school students were 3.19 times (95% CI:1.71~5.93) more likely to have ADHD than females. ADHD was significantly associated with family history of mental disease (adjusted OR 8.69; 95%CI 1.93~39.22), lack of cell phones usage (adjusted OR 2.27; 95%CI 1.21~4.26), a road adjacent to child's residence (adjusted OR 2.21; 95%CI 1.20~4.05) and lack of seafood consumption (adjusted OR 2.08; 95%CI 1.08~4.00).
CONCLUSIONS
More research effort should be focused on determining the prevalence of ADHD and relevant factors among children living nearby industrial complexes.
