Hi all,
I'm weighing in a little late on the math and obesity discussion. Obviously, there are lots of great reasons to support active transportation beyond obesity -- the role
of physical activity and active transportation in reducing cancer and other chronic diseases, assisting in smoking cessation, preventing transportation injuries, addressing climate change, etc. But I too was a little troubled by this article's blithe dismissal
of physical activity having any role in obesity.
Poking around today, I found this fascinating journal article, which noted and hotly (for a journal article) disputed the claim that physical activity doesn't have a role
in obesity. Church TS, Thomas DM, Tudor-Locke C, Katzmarzyk PT, Earnest CP, et al. (2011) Trends over 5 Decades in U.S. Occupation-Related Physical Activity and Their Associations with Obesity. PLoS ONE 6(5): e19657.
http://www.plosone.org/article/info:doi/10.1371/journal.pone.0019657.
The authors analyzed occupational physical activity levels in a nationally representative sample over the past 50 years, and found that daily energy expenditure related
to work has dropped by more than 100 calories per day in men and women. They conclude that this decrease likely plays a significant factor in the increase in obesity levels, and they note specific flaws in the assumptions that food intake alone accounts for
obesity levels. The most interesting quote to me was:
Given that it is unlikely that there will be a return to occupations that demand moderate levels of physical activity; our findings provide further
strong evidence of the public health importance of promoting physically active lifestyles outside of the work day. Our estimation of a reduction of more than 100 calories per day in occupation-related energy expenditure over the last 50 years would have been
adequately compensated for by meeting the 2008 federal physical activity recommendations of 150 minutes per week of moderate intensity activity or 75 minutes per week of vigorous intensity activity.
There are many, many articles assessing the relationship between obesity and physical activity levels and interventions, with various results – e.g.
http://www.activelivingresearch.org/files/ALR_Brief_ActiveTransportation.pdf,
http://www.saferoutespartnership.org/resourcecenter/research/impact-of-physical-activity, etc. But this was one of the few articles that directly addressed the notion that physical activity levels had been unchanged over the last several decades, and I
found it particularly convincing.
That said, it would definitely be interesting to hear researchers in the field hash out the eating versus physical activity debate. If anyone can find a resource featuring
such a discussion among knowledgeable individuals, please share!

That's all well and good, but it does not override the documented benefits of physical activity for people of all weights.

Subject: Call for Abstracts: 2012 Health Disparities Summit
[cid:image001.png@01CCFD1D.89670210]
CALL FOR ABSTRACTS
The 2012 Summit on the Science of Eliminating Health Disparities is now accepting abstracts for program sessions. All abstracts must be submitted no later than 5:00 p.m. Eastern Time on June 15, 2012. The abstract submission website
will be available within the next few days with more detailed information. You will receive a follow-up e-mail as soon as the site is available for abstract submissions.
The Summit is organized around the core principle of integrating science, policy, and practice, and offers a forum to advance scholarship and translate new knowledge into action.
Presentation Categories
Abstracts will be accepted in three categories: posters, oral presentations, and integrated panel presentations. Applicants may submit abstracts to more than one category, but each submission must be based on a separate research project.
Additional information about each category is available below.
Poster Presentations
Abstracts accepted in this category will be presented during the poster session on either November 1st or November 2nd, 2012. You will receive further details about the scheduled presentation date if your abstract is accepted.
Word Limit: Please limit poster abstracts to 300 words.
Oral Presentations
Oral presentations will take place in a roundtable panel format. Each panel will have an assigned moderator in order to promote dialogue and stimulate discussion. Abstracts that are accepted for oral presentations will be presented as
concurrent sessions. There is also the option of submitting an abstract in this category with the option to be considered for a poster presentation if the abstract is not accepted for oral presentation.
Word Limit: Please limit oral presentation abstracts to 300 words.
Integrated Panel Presentations
Integrated panel presentations are designed to allow a group of presenters from diverse disciplines (i.e., Science, Practice, and Policy) to discuss health disparities and related findings on a similar theme. Abstracts for this category
should focus on science, practice, policy, and include a community component or discuss societal issues that influence health disparities.
Word Limit: Please limit integrated panel presentation abstracts to 500 words. This should also include the presentation title for each panelist.
Presentation Tracks
Proposals, regardless of category, should also fall under one of three tracks:
Track 1: Translational and Transdisciplinary Research These presentations should promote the integration of science, practice and policy.
* Science or research abstracts might include basic and applied, health services, patient-oriented, epidemiological, environmental, behavioral, and social sciences research related to health disparities.
* Policy-oriented abstracts delve into policies linked to health or healthcare, or other areas impacting health such as public, social, and economic policies.
* Practice abstracts examine public health practice related to community health, healthcare, or social services delivery, and education and training.
Applicants must clearly articulate how findings lead to new knowledge in science, practice, or policy interventions in health disparities. For example, policy abstracts should include the scientific evidence or practice concept that
led to the policy. If the submission is a science abstract, then applicants should indicate how the science translates into either practice or policy.
Themes: The following themes fall under Track 1: Translational and Transdisciplinary Research
* Integrating Biological, Social, Behavioral and Environmental Determinants of Health
* Health Disparity Populations, Disease Conditions and Risk Factors
* Primary Prevention and Health
* Discrimination, Racism and Stress
* Healthcare Disparities and Quality Research
* Best Practices and Approaches for Community Engagement
* Health Information Technology
* Global Population Health
Track 2: Capacity-Building and Infrastructure Abstracts submitted under Track 2: Capacity-Building and Infrastructure, will explore the challenges and opportunities associated with building capacity for research, public health and primary
care practice, services delivery, training, and education. These presentations will also investigate the implementation and sustainability of infrastructure and economic development in disparate communities.
Themes: The following themes fall under Track 2: Capacity-Building and Infrastructure
* Multi-sectoral Capacity-Building
* Health Workforce
* Community Capacity-Building and Sustainable Economic Development
* Data and Research Evaluation
Track 3: Outreach, Partnerships, Collaborations, and Opportunities Eliminating health disparities requires effective outreach, partnerships, and collaborations across federal agencies, academic institutions, foundations, non-profit and
private organizations. Track 3: Outreach, Partnerships, Collaborations, and Opportunities, provides a venue for representatives from various agencies and organizations to showcase their innovative partnerships, outreach, and dissemination efforts, including
successful collaborations on addressing health disparities.
Themes: The following themes fall under Track 3: Outreach, Partnerships, Collaborations, and Opportunities
* Public Public-Private Partnerships
* Community Partnerships
* Outreach Dissemination
* Global Health Networks
General Guidelines
* Abstracts will be peer reviewed
* Authors must select the track and theme under which their abstracts should be considered. Abstracts may be submitted under only one Summit theme, and must be related to one or more of the topics listed under the selected theme.
* General selection criteria will be based on: (1) quality of abstract; (2) implications for health disparities research, policy, or practice, or its application; (3) new insights for health disparities research or its application;
(4) clarity and completeness of abstract; and (5) relevance to specified theme.
* Applicants may submit abstracts to more than one category, but each submission must come from a distinct research project.
* All abstract submissions are final, no changes or modifications will be permitted.
Abstract Awards/Recognition: Abstracts will be considered for recognition in the following award categories: outstanding scientific poster, outstanding policy poster, outstanding public health practice poster, outstanding clinical practice
poster, and outstanding community-based health disparities research or intervention poster. Early investigators, junior faculty, community researchers, and policy professionals are eligible for recognition. More details to come.
