[Unintentional injuries in childhood and adolescence: current prevalence, determinants, and trends: results of the KiGGS study: first follow-up (KiGGS Wave 1)].

BACKGROUND

In Germany and worldwide, unintentional injuries (UI) are a major health threat for children and adolescents. The first follow-up of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS Wave 1, 2009-2012) continued the national UI monitoring that started with the KiGGS baseline study (2003-2006). The present analysis provides updated information and for the first time gives indications on time trends.

METHODS

KiGGS Wave 1 is a combined nationwide cross-sectional and longitudinal survey by the Robert Koch Institute (RKI) providing information about 12,368 participating children and adolescents (0-17 years old; response rates: 38.8% first time invited, 72.9% reinvited). Parents were asked about their children's UI and poisonings via telephone interviews. Information on UI is available for 11,665 children and adolescents (1-17 years old). The 12-month prevalence rate and 95% confidence interval were calculated, and KiGGS Wave 1 was compared with the KiGGS baseline study. The Rao-Scott chi-square test corrected over the F distribution was used to test for the statistical significance of subgroup differences and trend effects.

RESULTS

Within the previous 12 months, 15.5% of all children and adolescents aged 1-17 years were medically treated for UI. UI were significantly more prevalent among boys (17.0%) than among girls (14.0%), and 3.4% of the subjects had more than one accident leading to UI. One in eight children and adolescents who suffered UI stayed in hospital (12.3%) for inpatient treatment for at least one night. The home, childcare and educational institutions, and sports facilities/playgrounds were the predominant accident locations. Compared to the baseline study, neither the overall prevalence of UI nor the gender- and age-specific patterns changed significantly.

CONCLUSION

Since a large proportion of UI is avoidable, knowledge of high-risk subgroups and accident locations is of particular use for prevention. KiGGS Wave 1 makes an important contribution to the comprehension of these issues. The transfer of research into practice is of particular importance for the avoidance of UI.
