Socio-structural determinants of physical activity behavior in children and adolescents
The purpose of this study is to analyze the influence of socio-structural determinants of physical activity (PA) behavior in children and adolescents. We expected that socioeconomic status, social support, and physical environment influence PA directly while socioeconomic status also has an indirect influence via social support and physical environment. Cross-sectional data from the German Motorik-Modul study (MoMo) were used (Wave 2, 2014-2017).…
Physical Activity and Recurrent Pain in Children and Adolescents in Germany—Results from the MoMo Study
Recurrent pain can be a significant disruption in the activities of daily life, and is not only a health problem in adults but also in children and adolescents. This study analyzed the prevalence of recurrent pain in the current sample (n = 1516; 11-17 years (mean age = 14.4 ± 2.0 years); 50.8% female) of a nationwide study in Germany, evaluated the association of participants' device-based physical activity (PA) with the prevalence of recurrent …
A Study on the Psychometric Properties of the Short Version of the Physical Activity Enjoyment Scale in an Adult Population
A new measure of the short form of the Physical Activity Enjoyment Scale (PACES-S), including four items, has been developed that focuses on the subjective experience of enjoyment. As validation has so far only been conducted in a youth population, the purpose of the present article was to test the psychometric properties of the measure in an adult population in three studies. In the first study ( n = 1017) the results supported the unidimensiona…
Community networks of sport and physical activity promotion
The study provided valid and robust findings on significant mechanisms and conditions of interorganizational cooperation in community networks focused on sport and physical activity promotion. Based on the results, implications for the development and most efficient governance of these networks can be derived
Changes of Self-Rated Health Status, Overweight and Physical Activity During Childhood and Adolescence—The Ratchet Effect of High Parental Socioeconomic Status
Childhood and adolescence are important life periods for the development of health status and physical activity (PA) behaviours. This study analyses the stability and potential changes of self-rated health status, overweight and PA behaviour over time, specifically focusing on the age and the socioeconomic status of children and adolescents. We employ representative longitudinal data for German children and adolescents from the Motorik-Modul Stud…

The Impact of Covid-19 on the Interrelation of Physical Activity, Screen Time and Health-Related Quality of Life in Children and Adolescents in Germany
Reduced physical activity (PA) and prolonged screen time (ST) negatively influence health-related quality of life (HRQoL), a protective factor against illness and mortality. Studies addressing the relationship between PA, ST, and mental health in youth are scarce, especially in times with high mental health burdens like the COVID-19 pandemic. The purpose of this examination was to investigate whether PA, ST, and HRQoL before COVID-19 predict PA, …
Standing Breaks in Lectures Improve University Students’ Self-Perceived Physical, Mental, and Cognitive Condition
While adolescents and adults should limit high levels of sedentary behavior, university students spend large amounts of time on sedentary activities. The aim of this study was to investigate the effect of this prolonged sitting on students' self-perceived physical, mental, and cognitive condition and to answer the question of whether simple standing breaks in lectures can help students improve these conditions and for example feel more concentrat…
A Short Version of the Physical Activity Enjoyment Scale
The results indicate that PACES-S is a reliable and valid instrument that may be particularly useful to measure physical activity enjoyment in large-scale studies. It shows comparable measurement properties as the long version of PACES
Indicators to Assess Physical Health of Children and Adolescents in Activity Research—A Scoping Review
Sufficient physical activity can help promote and maintain health, while its lack can jeopardize it. Since health and physical activity lay their foundation for later life in childhood and adolescence, it is important to examine this relationship from the beginning. Therefore, this scoping review aims to provide an overview of physical health indicators in children and adolescents in research on the effects of physical activity and sedentary beha…
Relating outdoor play to sedentary behavior and physical activity in youth - results from a cohort study
In Study 1, outdoor play was negatively related to SB cross-sectionally. In Study 2, outdoor play in early childhood was negatively related to PC and Gaming time in later childhood. Thus, providing outdoor play opportunities, especially during early childhood, has potential to prevent SB. Future research should investigate longitudinal relationships using device-based assessments for SB and MVPA
Comparison of self-reported & device-based, measured physical activity among children in Germany
Children and adolescents living in Germany show a very low adherence to the WHO guideline on PA. While younger children are much more active with their free play, especially children over 10 years of age and especially girls should be the target of programs to increase PA
Physical activity and screen time of children and adolescents before and during the Covid-19 lockdown in Germany
The impact of COVID-19 on social life has been drastic and global. However, the different numbers of cases and different actions in different countries have been leading to various interesting yet unexplored effects on human behavior. In the present study, we compare the physical activity and recreational screen time of a representative sample of 1711 4- to 17-year-olds before and during the strictest time of the first COVID-19 lockdown in German…
Representative Percentile Curves of Physical Fitness From Early Childhood to Early Adulthood
Introduction: The aim of this analysis is to report sex- and age-specific physical fitness percentile curves from childhood to early adulthood in a nationwide sample in Germany. Already in childhood, physical fitness is considered as one of the most important health markers. From a developmental and preventive perspective, physical fitness levels are relatively stable from childhood to early adulthood. Thus, it is important to monitor physical fi…
Social Support and Modelling in Relation to Physical Activity Participation and Outdoor Play in Preschool Children
Physical activity during early childhood is a prerequisite for healthy development in many cases. The aim of this study was to assess the relationships of social modelling and support from parents, peers, and siblings and domain-specific physical activity participation in a nationwide sample of preschool boys and girls from Germany. 519 preschool children aged 4-6 and one of their parents participated in the 'MoMo' Wave 1 Study between 2009 and 2…
Exploratory Determined Correlates of Physical Activity in Children and Adolescents
Background : Physical activity is an important contributor to reducing the risk for a variety of diseases. Understanding why people are physically active contributes to evidence-based planning of public health interventions because successful actions will target factors known to be related to physical activity (PA). Therefore the aim of this study is to identify the most meaningful correlates of PA in children and adolescents using a large, repre…
Physical Activity of German Children and Adolescents 2003–2012
Organized and unorganized physical activity (PA) hold an important role in the daily life of children and adolescents. Regular representative tracking of PA in different settings is important to evaluate social trends and implemented interventions. In this paper, representative PA data of German children and adolescents from the MoMo Baseline-Study (2004, n = 4528) are compared to those of Wave 1 (2010, n = 3994). Participants aged 4-17 were draw…
Subjektivierung und gesellschaftliche Transformation
The process of transformation is understood as a continuing series of challenges and responses, in which social change often arises from the strains between social practices, institutional structures, societal beliefs and self-descriptions, on the one hand, and the actors’ orientations and aspirations, on the other. Explicit and implicit rules and expectations do not necessarily correspond. Focussing on the actors’ perspectives and roles in the p…

Hegels System der Sittlichkeit
Das "System der Sittlichkeit" (1802/03) stellt die erste Vorform von Hegels Philosophie des Geistes dar. In seinem Versuch einer philosophischen Rekonstruktion der Sittlichkeit fragt Hegel, wie sich das moderne Subjekt in die verschiedenen Sphären des gesellschaftlichen und politischen Lebens integriert. Er sucht nach den Bindungskräften, die das in seiner Persönlichkeit dem Anspruch nach unverletzliche Individuum vor Isolierung und Entfremdung b…

Bureaucrats as Modernizing Brokers? Clientelism in Colombia
A growing literature suggests that important features of many political systems can be explained through an analysis of patron-brokerclient relationships within these systems.1 Such relationships involve the reciprocal exchange of goods and services.2 They are multiplex and require the proximity and socioeconomic inequality of the participants.3 Party politics sometimes draw these clientelist relations into the political process. When this occurs…
La Violencia Revisited
Lying at the heart of the problem in analyzing Colombian violence is the relative poverty of conceptual frameworks not only for dealing with violence but with the institutions and processes and traditions which form the social environment of the society. In the following pages I shall argue that a dialectic between violence and patron-client relations offers a useful analytical framework. The first part will deal with the historical dynamics of C…

Women in Colombia
For] women to begin to participate more fully in politics on an equal par with men, the changes that have to take place go far beyond the raising of consciousness of women themselves, as well as of the men. Major changes will also be necessary in the structure of the society, in particular in the relationship between the two institutions-the family and the polity.In this concluding paragraph of a paper on Brazilian women, Blachman (1972) charts t…
