[Parental strain, inattention/hyperactivity symptoms and parent-reported ADHD in children and adolescents: results of the KiGGS study]. / Elterliches Belastungserleben, Unaufmerksamkeits­/Hyperaktivitätssymptome und elternberichtete ADHS bei Kindern und Jugendlichen: Ergebnisse aus der KiGGS-Studie.

BACKGROUND: A child's attention deficit hyperactivity disorder (ADHD) is associated with strain for the parents. In turn, psychosocial parental strain is associated with higher probabilities for the occurrence of inattention/hyperactivity symptoms (IHS) in their children. The aim of this paper is to assess the association between parental strain, IHS, and a parent-reported ADHD diagnosis of the children. METHODOLOGY: Based on data from n = 4596 participants of the KiGGS cohort (wave 2: 2014-2017), the type and extent of parental strain was set in relation to IHS and an ADHD diagnosis of the child in cross-sectional analysis. Frequencies, means, beta coefficients, and odds ratios adjusted for sex, age, socioeconomic status, and migration background are reported. RESULTS: In individual consideration, a greater number of parental strains were associated with IHS than with an ADHD diagnosis. In a multivariate analysis, financial worries and parenting problems/conflicts with the children were significant predictors of IHS and an ADHD diagnosis, respectively. In addition, four or more types of parental strain were associated with a higher likelihood of both IHS and an ADHD diagnosis. DISCUSSION: Financial and child-rearing strain are relevant to parents of children with IHS and an ADHD diagnosis. Interrelationships between parental stress and a child's IHS or an ADHD diagnosis can be assumed. To relieve their burden, prevention can either aim at improving the situation of ADHD-affected families or at improving the family's handling of the child's ADHD.

[Mental health surveillance at the Robert Koch Institute - strategies for monitoring the mental health of the population]. / Mental Health Surveillance am Robert Koch-Institut ­ Strategien zur Beobachtung der psychischen Gesundheit der Bevölkerung.

The continuous and systematic surveillance of the health of populations is fundamental for effective public health practice. In light of the growing importance of mental health within population health, a Mental Health Surveillance for Germany is being established at the Robert Koch Institute. Its aim is to continually provide reliable information on the current state and development of the mental health of the population.Three surveillance strategies are currently being pursued: 1) Regular comprehensive assessments aim to describe the mental health status of the population using a wide range of indicators and data sources and to observe long-term developments. They build on existing work in epidemiology and health services research. 2) High-frequency monitoring of a selection of indicators is used for the early detection of trends. 3) A continuous literature review collates current findings on mental health developments in the COVID-19 pandemic on a monthly basis. The latter two strategies were implemented in response to new information needs in the pandemic.This paper describes and discusses these three strategies and their functions, limitations, and potential for development. Their results are communicated through different forms of reporting and serve to identify needs for action and research in public mental health. The further development and long-term operation of the Mental Health Surveillance as a whole has the potential to facilitate the achievement of public mental health objectives and to contribute on different levels to the improvement of population health.

Prevalence and Time Trends of Self-Reported Mental Health Problems Among Children and Adolescents Between 11 and 17 Years in the KiGGS Study.

Objective: Knowledge about the prevalence of mental disorders in childhood and adolescence is important for clinicians and policymakers. This study examines the prevalence and trends in self-reported mental health problems among 11- to 17-year-olds in Germany. Method: We evaluated data from the self-report version of the Strength and Difficulties Questionnaire (SDQ) of 6,725 children and adolescents from the baseline of the German Health Interview and Examination Survey (KiGGS, 2003-2006) and 6,145 from its second wave (KiGGS wave 2, 2014-2017). Results: According to the SDQ total difficulties score, the prevalence estimates did not vary significantly between the study waves, neither regarding the category "abnormal" (9.3 % vs. 9.4 %) nor the pooled categories "borderline/abnormal" (16.9 % vs. 15.4 %). We confirmed the results by linear regression analyses using mean values instead of the SDQ categories. Analyses of the SDQ subscales revealed gender and age-specific time trends. Conclusions: These findings differ from those based on the SDQ parent report, which suggests significant declines in symptom load between the study waves. The results indicate the importance of integrating youth self-reports when measuring mental health problems, at least as part of a multi-informant approach.

[A Continuous Literature Review for Mental Health Surveillance during the Covid-19 Pandemic in Germany - Method, Selected Results and Lessons Learned]. / Kontinuierliches Literaturreview zur Surveillance der psychischen Gesundheit in Deutschland während der COVID-19-Pandemie ­ Methode, ausgewählte Ergebnisse und Lessons Learned.

In order to provide an up-to-date overview on changes in population's mental health during the COVID-19 pandemic, a continuous literature review was conducted. Building on a rapid review, systematic and hand searches were conducted monthly until December 31, 2022. Studies were assessed for observation periods, risk of bias and outcomes. Trends in depressive symptoms in adults were summarized by vote counting. 102 publications were included from 62 studies in the adult population. Studies declined over the course of the pandemic. Overall, 37% of the studies and 56% of the publications can assess trends in the population reliably. Among evidence for changes in depressive symptoms deteriorations predominated at last. The heterogeneity of results published by the end of 2022 limits evidence syntheses. Evidence of deterioration requires further surveillance. A continuous review can indicate evidence gaps at an early stage.

Development of a prototype for high-frequency mental health surveillance in Germany: data infrastructure and statistical methods.

In the course of the COVID-19 pandemic and the implementation of associated non-pharmaceutical containment measures, the need for continuous monitoring of the mental health of populations became apparent. When the pandemic hit Germany, a nationwide Mental Health Surveillance (MHS) was in conceptual development at Germany's governmental public health institute, the Robert Koch Institute. To meet the need for high-frequency reporting on population mental health we developed a prototype that provides monthly estimates of several mental health indicators with smoothing splines. We used data from the telephone surveys German Health Update (GEDA) and COVID-19 vaccination rate monitoring in Germany (COVIMO). This paper provides a description of the highly automated data pipeline that produces time series data for graphical representations, including details on data collection, data preparation, calculation of estimates, and output creation. Furthermore, statistical methods used in the weighting algorithm, model estimations for moving three-month predictions as well as smoothing techniques are described and discussed. Generalized additive modelling with smoothing splines best meets the desired criteria with regard to identifying general time trends. We show that the prototype is suitable for a population-based high-frequency mental health surveillance that is fast, flexible, and able to identify variation in the data over time. The automated and standardized data pipeline can also easily be applied to other health topics or other surveys and survey types. It is highly suitable as a data processing tool for the efficient continuous health surveillance required in fast-moving times of crisis such as the Covid-19 pandemic.

Time trends in mental health indicators in Germany's adult population before and during the COVID-19 pandemic.

Background: Times of crisis such as the COVID-19 pandemic are expected to compromise mental health. Despite a large number of studies, evidence on the development of mental health in general populations during the pandemic is inconclusive. One reason may be that representative data spanning the whole pandemic and allowing for comparisons to pre-pandemic data are scarce. Methods: We analyzed representative data from telephone surveys of Germany's adults. Three mental health indicators were observed in ~1,000 and later up to 3,000 randomly sampled participants monthly until June 2022: symptoms of depression (observed since April 2019, PHQ-2), symptoms of anxiety (GAD-2), and self-rated mental health (latter two observed since March 2021). We produced time series graphs including estimated three-month moving means and proportions of positive screens (PHQ/GAD-2 score ≥ 3) and reports of very good/excellent mental health, as well as smoothing curves. We also compared time periods between years. Analyses were stratified by sex, age, and level of education. Results: While mean depressive symptom scores declined from the first wave of the pandemic to summer 2020, they increased from October 2020 and remained consistently elevated throughout 2021 with another increase between 2021 and 2022. Correspondingly, the proportion of positive screens first decreased from 11.1% in spring/summer 2019 to 9.3% in the same period in 2020 and then rose to 13.1% in 2021 and to 16.9% in 2022. While depressive symptoms increased in all subgroups at different times, developments among women (earlier increase), the youngest (notable increase in 2021) and eldest adults, as well as the high level of education group (both latter groups: early, continuous increases) stand out. However, the social gradient in symptom levels between education groups remained unchanged. Symptoms of anxiety also increased while self-rated mental health decreased between 2021 and 2022. Conclusion: Elevated symptom levels and reduced self-rated mental health at the end of our observation period in June 2022 call for further continuous mental health surveillance. Mental healthcare needs of the population should be monitored closely. Findings should serve to inform policymakers and clinicians of ongoing dynamics to guide health promotion, prevention, and care.

Changes in mental health in the German child and adolescent population during the COVID-19 pandemic - Results of a rapid review.

Background: This rapid review examines changes in the mental health of the German child and adolescent population during the COVID-19 pandemic. Methods: The basis are 39 publications, which were identified by means of systematic literature search (until 19.11.2021) and manual search. The databases of the included publications were systematized with regard to their representativeness for the general population, and the indicators used were categorized with regard to the depicted constructs and their reliability. Results: The large majority of the studies took place at the beginning of the pandemic until the summer plateau 2020. Representative studies mainly reported high levels of pandemic-related stress, increases in mental health problems, and negative impacts on the quality of life. Non-representative studies showed mixed results. Vulnerable groups could only be identified to a limited extent. Both routine and care-related data showed declines in the outpatient and inpatient service utilisation during the various waves of the pandemic followed by catch-up effects. Children and adolescents turned out to be more vulnerable during the pandemic compared to adults, but their stress levels varied with the waves of the pandemic and the related containment measures. Conclusions: A future forward-looking crisis and pandemic management requires a close-knit and continuous surveillance of the mental health of children as well as an improved identification of risk groups.

The effects of mental health problems in childhood and adolescence in young adults: Results of the KiGGS cohort.

Mental health problems in childhood and adolescence may have effects into adulthood. With the KiGGS cohort, data are available for the first time that can be used to track the effects of internalising and externalising problems in childhood or adolescence into young adulthood on a national database. From the KiGGS baseline survey (2003-2006) to KiGGS Wave 2 (2014-2017), a total of 3,546 children and adolescents aged 11 to 17 years were tracked over a period of eleven years into young adulthood. Mental health problems in childhood or adolescence were variously associated with impaired mental health, lower life satisfaction and poorer quality of life and indicators of sexual and reproductive health in young adulthood. When psychosocial protective factors at the time of the KiGGS baseline survey were considered, the longitudinal correlations of internalising and externalising problems with indicators of mental health, life satisfaction and physical and psychological quality of life decreased, as did, to a lesser extent, the correlations with indicators of sexual and reproductive health and, for externalising disorders, also with low educational status (reference: medium). Implications for prevention and intervention are discussed.

Mental health of the adult population in Germany during the COVID-19 pandemic. Rapid Review.

This rapid review examines how the mental health of adults in the general population in Germany changed during the COVID-19 pandemic. We conducted a systematic literature search and included 68 publications as of July 30 2021. The underlying studies were classified according to their suitability for representative statements for the general population and for estimating changes in mental health over time. In addition, the observation period and operationalisation of outcomes were considered. The first wave of infection and the summer plateau were mapped by 65% of the studies. Studies that were particularly suitable for representative statements due to their research design showed mixed results, which tend to indicate a largely resilient adult population with a proportion of vulnerable individuals. A predominantly negative development of mental health was described by results from more bias-prone study designs. Routine data analyses showed decreases in outpatient and especially inpatient care, increased use of a crisis service, mixed results for outpatient diagnoses, incapacity to work and mortality as well as indications of shifts in the spectrum of diagnoses. As the current evidence is ambiguous, generalised statements should be reflected in favour of a differentiated view. There is a need for research on the further course of the pandemic, specific risk groups and the prevalence of mental disorders.

Individual trajectories of asthma, obesity and ADHD during the transition from childhood and adolescence to young adulthood.

The German Health Interview and Examination Survey for Children and Adolescents (KiGGS) provides comprehensive and reliable data on the health situation of the upcoming generation. The KiGGS cohort accompanies participants from the KiGGS baseline study (2003-2006) into adulthood. Until now, two follow-up surveys of the cohort have been implemented with KiGGS Wave 1 (2009-2012) and KiGGS Wave 2 (2014-2017). In KiGGS Wave 2, the cohort was supplemented by the in-depth study 'Family and care-specific factors influencing the development, trajectories and effects of mental disorders (especially ADHD), obesity and allergic diseases (especially asthma)'. One aim of the study was to identify individual trajectories of these health disorders. For this purpose, probabilities for typical transitions from the KiGGS baseline study to KiGGS Wave 2 were calculated. An important result is that many participants who had asthma, obesity or ADHD at KiGGS baseline still had the disease more than ten years later: Over a third still had asthma (35%) or ADHD (37%), and almost half were still affected by obesity (47%). The results point to the need for early preventive measures to stop these potentially chronic diseases from developing in childhood and adolescence.
