Abstract
ADHD and sleep-problems frequently overlap and their relationship is complex and bidirectional. The association between ADHD and sleep-problems has been little studied in our community.
Objectives To find out the frequency of sleep-problems among ADHD children from 6–14 year old in Andalusia, Spain.
Methods Prevalence study. Target population: school-students 6–14y=686.332 children; centres=2.493. Multistage cluster sampling centres=74.
Method Questionnaires-DSM-IV-TR-ADHD and performance Vanderbilt-parents-and-teachers, sleep-questionnaire (BEARS), interview and medical examination.
Results N=1963.
Meet criteria-DSM-IV-R-ADHD=157, male=111, female=46; ADHD-IA=62, ADHD-HI=31, ADHD-C=64; control=197Comorbidity ADHD-sleep-problems: Sleep-problems in the first year of life: 36%-ADHD, 25%-control. (p=0.03). Bedtime resistance:30%–ADHD, 6%-control.(p=0.000). Daytime sleepiness:10%-ADHD, 1.5%-control.(p=0.000). Night- Awakenings:14%-ADHD, 2%-control.(p=0.000).

Enuresis:18%-ADHD, 4.6%-control.(p=0.000)Regular time for bed: only 36%-ADHD. Bedsharing:18%-ADHD.≥ 3 sleep problems: 36%-ADHD. 12%- control. The association between ADHD subtypes and sleep-problems showed significant differences.
Conclusions The children with ADHD had more sleep-problems that control children.
The relationship between sleep disorders and ADHD should be considered by paediatricians as part of the global approach to the management of ADHD.
