Trends in health inequalities in childhood and adolescence in Germany: Results of the HBSC study 2009/10 - 2022.

Background: Many studies have identified health inequalities in childhood and adolescence. However, it is unclear how these have developed in recent years, particularly since the COVID-19 pandemic. Methods: Analyses are based on the German data from the international Health Behaviour in School-aged Children (HBSC) study from 2009/10 (n = 5,005), 2013/14 (n = 5,961), 2017/18 (n = 4,347), and 2022 (n = 6,475). A total of 21,788 students aged approximately between 11 and 15 years were included. Socioeconomic status (SES) was assessed using the Family Affluence Scale (FAS). Several health indicators were analysed stratified by gender using bivariate and multivariate analysis methods. Results: In 2022, there are clear socioeconomic inequalities in life satisfaction, self-rated health, fruit and vegetable consumption, and physical activity. These inequalities remained largely constant or increased between 2009/10 and 2022. Between 2017/18 and 2022, no significant changes in inequalities were found. Conclusions: Health inequalities are persistent and reduce the chances of growing up healthy. There is no evidence that inequalities in the analysed outcomes have changed during the pandemic period (between 2017/18 and 2022). Rather, the changes in the health indicators seem to affect all adolescents in a similar way.

Concept and methodology of the Health Behaviour in School-aged Children (HBSC) study - Insights into the current 2022 survey and trends in Germany.

Background: Health Behaviour in School-aged Children (HBSC) is one of the largest international studies on child and adolescent health and cooperates with the World Health Organization (WHO). In Germany, adolescents aged 11, 13 and 15 are surveyed every four years about their health, health behaviour and social conditions. This article describes the HBSC study and in particular the methodology of the current 2022 survey and prior surveys conducted between 2009/10 and 2017/18. Method: 174 schools with a total of 6,475 students participated in the 2022 survey. The survey was conducted using questionnaires and covered a wide range of topics (including mental health, physical activity, bullying experiences, social determinants of health and experiences related to COVID-19). The 2022 survey was complemented by a school principal survey (N = 160). In addition to the current sample, the samples of the three previous surveys with representative data for Germany are presented: 2009/10 (N = 5,005), 2013/14 (N = 5,961) and 2017/18 (N = 4,347). Discussion: The health of children and adolescents is of great public health importance. The HBSC study makes a substantial contribution by providing internationally comparable results, analysing trends, and providing stakeholders with comprehensive and representative health monitoring data.

Socioeconomic status, stressful life situations and mental health problems in children and adolescents: Results of the German BELLA cohort-study.

AIM: Children and adolescents with low socioeconomic status (SES) suffer from mental health problems more often than their peers with high SES. The aim of the current study was to investigate the direct and interactive association between commonly used indicators of SES and the exposure to stressful life situations in relation to children's mental health problems. METHODS: The prospective BELLA cohort study is the mental health module of the representative, population-based German National Health Interview and Examination Survey for children and adolescents (KiGGS). Sample data include 2,111 participants (aged 7-17 years at baseline) from the first three measurement points (2003-2006, 2004-2007 and 2005-2008). Hierarchical multiple linear regression models were conducted to analyze associations among the SES indicators household income, parental education and parental unemployment (assessed at baseline), number of stressful life situations (e.g., parental accident, mental illness or severe financial crises; 1- and 2-year follow-ups) and parent-reported mental health problems (Strength and Difficulties Questionnaire; 2-year follow-up). RESULTS: All indicators of SES separately predicted mental health problems in children and adolescents at the 2-year follow-up. Stressful life situations (between baseline and 2-year follow-up) and the interaction of parental education and the number of stressful life situations remained significant in predicting children's mental health problems after adjustment for control variables. Thereby, children with higher educated parents showed fewer mental health problems in a stressful life situation. No moderating effect was found for household income and parental employment. Overall, the detected effect sizes were small. Mental health problems at baseline were the best predictor for mental health problems two years later. CONCLUSIONS: Children and adolescents with a low SES suffer from multiple stressful life situations and are exposed to a higher risk of developing mental health problems. The findings suggest that the reduction of socioeconomic inequalities and interventions for families with low parental education might help to reduce children's mental health problems.

Socioeconomic inequalities and mental health problems in children and adolescents: a systematic review.

Socioeconomic inequalities in health are an important topic in social sciences and public health research. However, little is known about socioeconomic disparities and mental health problems in childhood and adolescence. This study systematically reviews publications on the relationships between various commonly used indicators of socioeconomic status (SES) and mental health outcomes for children and adolescents aged four to 18 years. Studies published in English or German between 1990 and 2011 were included if they reported at least one marker of socioeconomic status (an index or indicators, e.g., household income, poverty, parental education, parental occupation status, or family affluence) and identified mental health problems using validated instruments. In total, 55 published studies met the inclusion criteria, and 52 studies indicated an inverse relationship between socioeconomic status and mental health problems in children and adolescents. Socioeconomically disadvantaged children and adolescents were two to three times more likely to develop mental health problems. Low socioeconomic status that persisted over time was strongly related to higher rates of mental health problems. A decrease in socioeconomic status was associated with increasing mental health problems. The strength of the correlation varied with age and with different indicators of socioeconomic status, whereas heterogeneous findings were reported for gender and types of mental health problems. The included studies indicated that the theoretical approaches of social causation and classical selection are not mutually exclusive across generations and specific mental health problems; these processes create a cycle of deprivation and mental health problems. The review draws attention to the diversity of measures used to evaluate socioeconomic status, which might have influenced the comparability of international epidemiological studies. Furthermore, the review highlights the need for individual-level early childhood interventions as well as a reduction in socioeconomic inequalities at a societal level to improve mental health in childhood and adolescence.
