Mental health problems in children and adolescents in Germany. Results of the cross-sectional KiGGS Wave 2 study and trends

Mental health problems in children and adolescents are associated with individual and family-related constraints as well as social costs. 20.0% of children and adolescents showed mental health problems at the KiGGS baseline study (2003-2006). This study investigates the current prevalence for KiGGS Wave 2 (2014-2017) as well as time trends in comparison with the KiGGS baseline study. Mental health problems were assessed for 3- to 17-year-old children and adolescents by using the parent-based version of the Strengths and Difficulties Questionnaire (SDQ). For KiGGS Wave 2, the prevalence of mental health problems was 16.9%. A decreasing trend is pronounced particularly among boys between 9 and 17 years of age. Mental health problems are displayed more frequently by girls and boys from families with a low socioeconomic status compared to their peers from families with a medium or high socioeconomic status. These findings are discussed in the light of various measures and actions in health promotion and health care.
