Field tests measuring the same construct, in this case, aerobic capacity, use different scales, which makes fitness assessment of children and youth potentially confusing. The Primary Field Test Centered Equating Method has been developed to set tests on the same scale, as illustrated by the conversion of Progressive Aerobic Capacity Endurance Run (PACER) scores to 1-mile run/walk times to estimate VO(2)max. ⋯ The Primary Field Test Centered Equating Method performs as well or better in estimating VO(2)max as several other models using PACER scores, especially for boys, and thus may be successfully used in practice. More research is needed to understand the relatively low prediction and classification accuracy in girls.

This is one of six short papers that describe additional innovations to help integrate public health into medical education; these were featured in the "Patients and Populations: Public Health in Medical Education" conference. They represent relatively new endeavors or curricular components that had not been explored in prior publications. Although evaluation data are lacking, it was felt that sharing a description of the public health, prevention, population health, and policy (P4) curriculum at the University of Arizona College of Medicine, Phoenix (UACOM-P), would be of value to medical educators.

Research examining the association between environmental attributes and physical activity among youth is growing. An updated review of literature is needed to summarize the current evidence base, and to inform policies and environmental interventions to promote active lifestyles among young people. ⋯ Mode of measurement greatly influenced the consistency of associations between environmental attributes and youth physical activity. For both children and adolescents, the most consistent associations involved objectively measured environmental attributes and reported physical activity. The most supported correlates for children were walkability, traffic speed/volume, access/proximity to recreation facilities, land-use mix, and residential density. The most supported correlates for adolescents were land-use mix and residential density. These findings support several recommendations for policy and environmental change from such groups as the IOM and National Physical Activity Plan.

Randomized Controlled Trial
Telephone counseling and attendance in a national mammography-screening program a randomized controlled trial.
In Germany, a mammography-screening program (MSP) was implemented on a national level. It complies with all criteria of the European guidelines for quality assurance in screening mammography; however, the attendance rate is 54%, falling short of the target attendance rate of 70%. The aim of this study was to investigate whether additional telephone counseling improves attendance among nonresponders and the level of satisfaction with telephone counseling. ⋯ Individual telephone counseling for nonresponders to a national program for breast cancer screening was well accepted by participants and effective.

Evidence, mainly from cross-sectional studies, suggests that physical activity is a potentially important modifiable factor associated with physical performance and strength in older age. It is unclear whether the benefits of physical activity accumulate across life or whether there are sensitive periods when physical activity is more influential. ⋯ There are cumulative benefits of physical activity across adulthood on physical performance in midlife. Increased activity should be promoted early in adulthood to ensure the maintenance of physical performance in later life.
