[Utilization of Occupational Therapy in Children - Results from the KiGGS Basis Survey].

BACKGROUND
A population-based analysis on use of occupational therapy by child's parentally reported health restrictions and socio-demographic determinants is missing.


PATIENTS AND METHODS
The basis KiGGS survey (2003 to 2006) reports on health in 17 641 children aged 0 to 17 years. The use of occupational therapy in the last 12 months could be ticked as other therapies with a free text field to name occupational therapy or others. Health restrictions potentially relevant for the use of occupational therapy and sociodemographic factors were assessed. The proportion of use of occupational therapy explained by the health restrictions was estimated by the population attributable risk fraction.


RESULTS
The average use of occupational therapy for 3 to 13-year-olds was 2.4%. There was no association with the socioeconomic status; Children with immigration background used occupational therapy less often (e. g. age group 3 to 6 years: ORadjusted 0.2 [95-% KI: 0.1-1.0]). The proportion of occupational therapy explainable by the health restrictions considered ranged from 45% (3 to 6 years) to 65% (11 to 13 years).


DISCUSSION
The lower use of occupational therapy in the KiGGS survey compared to health insurance reports may be explained by the ascertainment method. A lower use of occupational therapy related to immigration background matches lower use for physician visits.


CONCLUSION
The causes for the low proportion of explained occupational therapy in young children and the lower use in children with immigration background warrant further research.
