Research assumes that post-secondary pathways have immediate and/or long-term impacts on health and well-being, but empirical investigations on this are scarce and restricted to few countries. Therefore, this study traced the development of health and well-being throughout the highly institutionalised school-to-work transition (STWT) in Germany. Methods: We used longitudinal data of the National Educational Panel Study (NEPS), a representative sample of 11,098 school-leavers (50.5\% girls) repeatedly interviewed between 2011 and 2020. We estimated the effect of post-secondary transitions on self-rated health and subjective well-being by applying fixed-effects (FE) regression, elimi-nating bias resulting from time-constant confounding and self-selection into different pathways. A multiple-sample strategy was used to account for the increasing diversity of STWTs patterns. Models were controlled for age, as well as household and residential changes to minimise temporal heterogeneity. Results: Findings indicate that leaving school was good for health and well-being. Compared with participants who did not find a training position after school, direct transitions to vocational training or university were linked to higher absolute levels of health and well-being, but also to a lower relative decline over time. Furthermore, upward transi-tions (e.g. to programs leading to better education or from unemployment to employment) were associated with improvements in health and well-being, while downward transitions were followed by deteriorations. Conclusion: Findings suggest that school-leave is a sensitive period and that post-secondary pathways provide young people with different abilities to maintain health and well-being. Youth health interventions might benefit when setting a stronger focus on unsuccessful school-leavers.}, language = {en} } @misc{DeindlDiehlSpalleketal., author = {Deindl, Christian and Diehl, Katharina and Spallek, Jacob and Richter, Matthias and Sch{\"u}ttig, Wiebke and Rattay, Petra and Dragano, Nico and Pischke, Claudia R.}, title = {Self-rated health of university students in Germany-The importance of material, psychosocial, and behavioral factors and the parental socio-economic status}, series = {Frontiers in Public Health}, volume = {11}, journal = {Frontiers in Public Health}, issn = {2296-2565}, doi = {10.3389/fpubh.2023.1075142}, abstract = {Health inequalities start early in life. The time of young adulthood, between late teens and early twenties, is especially interesting in this regard. This time of emerging adulthood, the transition from being a child to becoming an adult, is characterised by the detachment from parents and establishing of an own independent life. From a health inequality perspective, the question about the importance of the socio-economic background of parents is important. University students are an especially interesting group. Many students come from a privileged background and the question of health inequality among university students has not yet been properly studied. Based on the National Educational Panel Study (NEPS), we analysed health inequalities among 9,000 students in Germany ({\O} 20 years in the first year of their studies) over a period of eight years. We found that university students in Germany report a good and very good health. Yet, we still found substantial health inequalities. Students whose parents had a higher occupational status also reported less health problems. We were also able to tie health inequality on health behaviour, psychosocial resources, and material conditions.}, language = {en} } @misc{ReuterDiehlRichteretal., author = {Reuter, Marvin and Diehl, Katharina and Richter, Matthias and Sundmacher, Leonie and H{\"o}vener, Claudia and Spallek, Jacob and Dragano, Nico}, title = {A longitudinal analysis of health inequalities from adolescence to young adulthood and their underlying causes}, series = {Advances in Lifecourse Research}, volume = {Vol. 59}, journal = {Advances in Lifecourse Research}, issn = {1879-6974}, doi = {10.1016/j.alcr.2024.100593}, abstract = {Research suggests that children of low-educated parents face greater health burdens during the passage from adolescence to young adulthood, as they are more likely to become low-educated themselves, establish behavioural and psychosocial disadvantages, or being exposed to unhealthy working conditions. However, studies examining the development and drivers of health inequalities during this particular life stage are limited in number and have produced varied results. This study investigates trajectories of self-rated health and overweight from 14 to 25 years of age, stratified by parental education, and explores the role of potential mediators (educational achievement, health behaviours, psychosocial factors, working conditions). We rely on prospective cohort data from the National Educational Panel Study (NEPS), a representative sample of 14,981 German ninth graders interviewed yearly from 2011 to 2021 (n = 90,096 person-years). First, we estimated random-effects growth curves for self-rated health and overweight over participants' age and calculated the average marginal effect of high versus low parental education. Second, a series of simulation-based mediation analyses were performed to test how much of health inequalities were explained by children's educational attainment (years of school education, years in university), health behaviours (smoking, alcohol, physical inactivity), psychosocial factors (number of grade repetitions, years in unemployment, chronic stress, self-esteem) and working conditions (physical and psychosocial job demands). We accounted for potential confounding by controlling for age, sex, migration background, residential area, household composition, and interview mode. Results show that higher parental education was related to higher self-rated health and lower probabilities of being overweight. Interaction between parental education and age indicated that, after some equalisation in late adolescence, health inequalities increased in young adulthood. Furthermore, educational attainment, health behaviours, psychosocial factors, and early-career working conditions played a significant role in mediating health inequalities. Of the variables examined, the level of school education and years spent in university were particular strong mediating factors. School education accounted for around one-third of the inequalities in self-rated health and one-fifth of the differences in overweight among individuals. Results support the idea that the transition to adulthood is a sensitive period in life and that early socio-economic adversity increases the likelihood to accumulate health disadvantages in multiple dimensions. In Germany, a country with comparatively low educational mobility, intergenerational continuities in class location seem to play a key role in the explanation of health inequalities in youth.}, language = {en} } @misc{WinterMoorMarkertetal., author = {Winter, Kristina and Moor, Irene and Markert, Jenny and Bilz, Ludwig and Bucksch, Jens and Dadaczynski, Kevin and Fischer, Saskia M. and Helmchen, Ronja M. and Kaman, Anne and M{\"o}ckel, Juliane and Rathmann, Katharina and Ravens-Sieberer, Ulrike and Reiß, Franziska and Schierl, Theresa and Sch{\"u}tz, Raphael and Sendatzki, Saskia and St{\"u}rmer, Elisabeth and Sudeck, Gorden and Richter, Matthias}, title = {Concept and methodology of the Health Behaviour in School-aged Children (HBSC) study - Insights into the current 2022 survey and trends in Germany}, series = {Journal of Health Monitoring}, volume = {9}, journal = {Journal of Health Monitoring}, number = {1}, issn = {2511-2708}, doi = {10.25646/11878}, pages = {99 -- 117}, abstract = {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).

These include regular standardized examinations (so called U/J examinations) and several vaccinations. Although strongly recommended, most of them are not mandatory. Our aim is to identify factors associated with the use of U/J examinations and vaccination against diphtheria, hepatitis B, Hib, pertussis, polio, and tetanus. While previous research has focused on sociodemographic factors, we also include socioeconomic, behavioral, and psychosocial factors. Methods: We analyzed cross-sectional data from 15,023 participants (aged 0-17 years) of the nationwide representative KiGGS Wave 2 Survey. Participation in U/J examinations was assessed using a questionnaire, filled out by participants and/or their parents. Information on vaccination status was drawn from the participants' vaccination booklets. To identify relevant determinants for the use of preventive examinations and vaccinations, unadjusted and adjusted logistic regression models were employed with up to 16 different independent variables. Results: Various independent variables showed an association with the use of preventive services. Higher socioeconomic status, absence of migration background, and lower household size were associated with significantly higher utilization of U examinations. Parents' marital status, area of residence, behavioral and psychosocial factors yielded insignificant results for most U/J examinations. Higher vaccination rates were found for children with no migration background, with residence in eastern Germany, lower household size, and with married parents. Conclusion: This study attempted to depict the influence of sociodemographic, psychosocial, and behavioral factors on the use of several preventive services. Our results indicate that predominantly sociodemographic variables influence the use of preventive services.

The material's self-heating effect results from irreversible changes in the material's microstructure that are directly coupled with the inelastic deformations. These processes are highly dissipative, which is reflected in the heat generation of the material. To describe such effects, a numerical framework that combines an elasto-viscoplastic Chaboche model with the Gurson Tvergaard Needleman damage approach is analysed and thermomechanically extended. This paper characterises the sample preparation, the experimental set-up, the development of the thermomechanical approach, and the material model. A user material subroutine applies the complete material model for the finite element software Abaqus 2022. To validate the material model and the parameters, a complex tensile test is performed. In order to check the finite element model, the energy transformation ratio is included in the evaluation. The numerical analyses of the mechanical stress evolution and the self-heating behaviour demonstrate good agreement with the experimental test. In addition, the calculation shows the expected behaviour of the void volume fraction that rises from the initial value of 0.0373\%to a higher value under a complex mechanical load.}, language = {en} } @misc{HerkeReuterMayeretal., author = {Herke, Max and Reuter, Marvin and Mayer, A. and Spallek, Jacob and Rattay, Petra and Moor, Irene and Richter, Matthias}, title = {Wie wirkt sich die sozio{\"o}konomische Komposition der Schule auf Ungleichheiten im subjektiven Wohlbefinden von Sch{\"u}lerinnen und Sch{\"u}lern in Deutschland aus?}, series = {Gesundheitswesen}, volume = {84}, journal = {Gesundheitswesen}, number = {08/09}, publisher = {Georg Thieme Verlag}, doi = {10.1055/s-0042-1753867}, pages = {826}, abstract = {Einleitung Zielsetzung des Beitrags ist es, zu untersuchen, inwiefern die sozio{\"o}konomische Komposition von Schulen mit dem Wohlbefinden von Sch{\"u}lerinnen und Sch{\"u}lern in Deutschland assoziiert ist. Konkret wurden die Assoziationen der Bildung, des Einkommens und des beruflichen Status der Eltern auf Individualebene und aggregiert auf Schulebene sowie die Interaktionen zwischen diesen Ebenen auf das subjektive Wohlbefinden von Sch{\"u}lern der Sekundarstufe I untersucht. Methoden Es wurden Daten der Startkohorte „Klasse 5" des Nationalen Bildungspanels (NEPS) herangezogen. Die Kohorte startete 2010 mit einer repr{\"a}sentativen Stichprobe von F{\"u}nftkl{\"a}sslern in Deutschland, welche j{\"a}hrlich nachverfolgt wurden. Es wurden Erhebungswellen von der f{\"u}nften bis zur neunten Klasse zusammengefasst. Damit konnten 14.265 Beobachtungen mit vollst{\"a}ndigen Angaben von 3.977 Sch{\"u}lerinnen und Sch{\"u}lern in 218 Schulen in den Analysen ber{\"u}cksichtigt werden. Mit Mixed-Models wurde getestet, ob die sozio{\"o}konomische Position auf individueller und/oder schulischer Ebene und die ebenen{\"u}bergreifende Interaktion dieser Indikatoren mit dem Wohlbefinden (adaptierter Personal Well-Being - School Children-Index) der Jugendlichen assoziiert ist. Es wurde f{\"u}r Alter, Geschlecht, Migrationshintergrund, Familienform, Schultyp und Notendurchschnitt kontrolliert. Ergebnisse Auf individueller Ebene war das elterliche Einkommen mit h{\"o}herem Wohlbefinden verbunden. Der berufliche Status der Eltern zeigte keine signifikanten Assoziationen. Auf Schulebene fanden wir einen geringen, positiven Zusammenhang zwischen dem durchschnittlichen elterlichen Einkommen und dem individuellen Wohlbefinden, aber auch einen m{\"a}ßig negativen Einfluss eines hohen Anteils hoch gebildeter Eltern auf das Wohlbefinden. In Sensitivit{\"a}tsanalysen blieben diese Zusammenh{\"a}nge auch bei separater Betrachtung dieser Indikatoren bestehen. Die Zusammenh{\"a}nge auf Individualebene wurden nicht durch die sozio{\"o}konomische Komposition von Schulen moderiert, es konnten keine signifikanten ebenen{\"u}bergreifende Interaktionen festgestellt werden. Schlussfolgerung Es wurde ein Zusammenhang der sozio{\"o}konomischen Zusammensetzung der Schule mit dem subjektiven Wohlbefinden der Jugendlichen gefunden.
