CI = confidence interval
CSHCN = Children with Special Health Care Needs
MEHM = Minimal European Health Module
ADHD = Attention Deficit Hyperactivity Disorder
* Total group of 12- to 17-year-olds with parental data on CSHCN weighted by the weighting factor from the baseline survey in order to ensure representativeness (weighted on the population as of 31 December 2004)
** Group of repeat participants of people who were aged between 12 and 17 at the time of KiGGS Wave 1; weighted with the longitudinal weight to compensate for the different chances of participating again and to correct for deviations from the population at the time of the baseline survey (31 December 2004)
