title: Steps towards permanently increasing physical activity in the population.
abstract: OBJECTIVE
  Maintaining recommended levels of physical activity throughout the lifespan is an important public health objective, considering this behaviour is positively associated with both physical and mental health across all age groups. This article provides an overview of selected publications with an exclusive focus on research relating to physical activity promotion published in the past 18 months.
  
  
  RESULTS
  Physical activity can be integrated during the life-course of individuals through recreational, transportation and occupational activities. A growing body of research on social-cognitive theories continues to inform the conceptualization and development of physical activity interventions.
  
  
  CONCLUSIONS
  Transitions during the life-course provide numerous challenges and opportunities for physical activity interventions. Multiple-level approaches across various settings and modes of delivery need to be taken into account to keep individuals active.
