Portion-size estimation is an important component of weight management. Literacy and numeracy skills may be important for accurate portion-size estimation. It was hypothesized that low literacy and numeracy would be associated with decreased accuracy in portion estimation. ⋯ In this study, many participants had poor portion-size estimation skills. Lower literacy skills were associated with less accuracy when participants were asked to serve a single serving. Opportunities may exist to improve portion-size estimation by addressing literacy.

Fatal all-terrain vehicle crashes: injury types and alcohol use.
Since the 1990s, West Virginia has led the U.S. in the per-capita death rate from all-terrain vehicle (ATV) crashes, with rates eight times the national average and continually increasing. A comprehensive assessment was conducted of ATV fatalities to provide critical guidance for community interventions and public health policy to prevent further deaths. ⋯ Fatal crash and injury types differ significantly depending on the location of ATV use, although alcohol and drug abuse are frequent risk factors in all types of ATV crashes. In addition to promoting helmet use, interventions are needed to address alcohol use among ATV users.

The rise in obesity levels in the U. S. in the past several decades has been dramatic, with serious implications for public health and the economy. Experiences in tobacco control and other public health initiatives have shown that public policy may be a powerful tool to effect structural change to alter population-level behavior. ⋯ Moving forward, timely evaluation of natural experiments is of especially high priority. A variety of policies intended to promote healthy weight in children and adults are being implemented in communities and at the state and national levels. Although some of these policies are supported by the findings of intervention research, additional research is needed to evaluate the implementation and quantify the impact of new policies designed to address obesity.

The University of California at Irvine Interdisciplinary Summer Undergraduate Research Experience (ID-SURE) program had three objectives: (1) designing an interdisciplinary health promotion training curriculum for undergraduate research fellows; (2) developing measures for evaluating and assessing program-related educational processes and products; and (3) comparing these educational process and product measures between groups of students who did or did not receive the training. ⋯ The findings from this study offer evidence for the efficacy of the ID-SURE program for training undergraduate students in transdisciplinary concepts, methods, and skills that are needed for effective scientific collaboration. Additionally, this study makes two important contributions to the development and evaluation of interdisciplinary health research training programs: (1) It presents and evaluates a novel curriculum for training undergraduate students in interdisciplinary theories, concepts, and methods of health promotion that can be replicated in other settings and contexts; (2) It provides and tests the reliability of new measures for evaluating interdisciplinary collaborative processes and develops objective criteria for rating the integrative and intellectual quality of students' research products.

Measuring food availability and access in African-American communities: implications for intervention and policy.
Obesity is a major public health concern in the U. S. As compared to whites, minority populations are disproportionately at risk, with the highest prevalence rates of overweight and obesity occurring among African American women. ⋯ A major challenge has been the need for reliable and valid measures to assess aspects of the neighborhood food environment that encourage or inhibit healthful eating behaviors and weight management. Investigators have made considerable gains in the development of tools and approaches to measure neighborhood food environments overall, but few studies focus on the specific challenges and issues associated with characterizing neighborhood food environments in communities of color. This paper highlights important considerations for measuring food environments in African-American neighborhoods and their implications for developing programmatic and policy solutions to reduce racial disparities in overweight.
