The Food and Drug Administration currently is assessing the public health impact of menthol cigarettes. Whether menthol cigarettes pose increased barriers to quitting is a critical issue because previous declines in smoking prevalence have stalled. ⋯ Smoking menthol cigarettes is associated with decreased cessation at the population level, and this association is more pronounced among black and Puerto Rican smokers. These findings support the recent calls to ban menthol flavoring in cigarettes.

Integrating public health into medical curricula poses a substantial challenge to educators. However, the needs of trainees and the population requirements of accrediting bodies provide a compelling call to action to improve how tomorrow's medical practitioners are prepared to incorporate public health into their practices. This article provides insights about the nature of the challenges, and it identifies opportunities and practical approaches to integrating public health content into medical school curricula. The paper incorporates authors' opinions with a synthesis of the discussions from a workshop at the 2010 "Patients and Populations: Public Health in Medical Education" conference.

Aerobic fitness (VO(2)max) is a key component of youth fitness testing. Criterion-referenced (CR) assessments are used in FITNESSGRAM(®) to assess health risk. ⋯ The Quadratic Model and Linear Model 2 provide valid estimates of VO(2)max and compare favorably to previous models. The CR validity evidence for the Quadratic Model and Linear Models developed in this study was slightly better than for the other models examined.

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.

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.
