Job mobility and job performance: beliefs about social and occupational (dis)advantages as mediators.

. Modern working conditions require an increased amount of spatial mobility from employed personnel. Research suggests that different types of job mobility might exert negative effects on well-being and health, and additionally have different costs and benefits for the work and the social domains.

Sporting activity, prevalence of overweight, and risk factors: cross-sectional study of more than 12 500 participants aged 16 to 25 years.

Background: Recent studies show that habits detrimental to health are becoming established ever earlier in life. Because most of these investigations focus on adolescents up to the age of 18 years, it is largely unknown whether and to what extent negative behavioral modifications are intensified in young adults.

Methods: Within the cross-sectional study "Fit fürs Leben" (Fit for Life) 12 835 volunteers aged 16 to 25 years were anthropometrically investigated and interviewed about their lifestyle and habits (sporting activity, nutrition and health-related behavior).
