Maximal expiratory airflow peaks early in the third decade of life, then gradually declines with age. The pattern of airflow through adulthood for individuals born very preterm (at <32 weeks' gestation) or with very low birthweight (<1501 g) is unknown. We aimed to compare maximal expiratory airflow in these individuals during late adolescence and early adulthood with that of control individuals born with normal birthweight (>2499 g) or at term.

ABSTRACTLiterature has shown that participation in physical activity is associated with a reduction in the incidence of certain cancers. Physical activity levels across the life course are low. Since cellular damage from an inactive lifestyle accumulates over time, promoting physical activity from childhood is fundamental for cancer prevention. To date, interventions to promote physical activity in children have been unsuccessful over the long term. Physical activity can be accrued through several domains including sport and active play. Research suggests that sport participation and not active play tracks from childhood to adulthood. Active play may be easier to promote because it does not necessitate a certain level of skill or competency, and is enjoyable. The purpose of the present paper is to encourage more research into all areas of active play to increase population physical activity levels across the life course and thus aid in the prevention of specific cancers.

The purpose of this systematic literature review was to examine current empirical research on general and respiratory health outcomes in adult survivors of bronchopulmonary dysplasia (BPD).

The workplace is ideal to encourage habitual physical activity, but little evidence exists on effective behaviour change interventions that lead to sustained behaviour. We aimed to address this gap by evaluating the effectiveness and cost-effectiveness of a loyalty-based intervention on physical activity in public sector employees.
