Evidence of associations between active transportation (walking and bicycling for transportation) and health outcomes is limited. Better understanding of this relationship would inform efforts to increase physical activity by promoting active transportation. Purpose
This study examined associations between active transportation and cardiovascular disease risk factors in U.S. adults. Methods
Using the 2007-2008 and 2009-2010 cycles of the National Health and Nutrition Examination Survey (NHANES), adults (N=9933) were classified by level of active transportation. Multivariable linear and logistic regression analyses controlled for sociodemographic characteristics, smoking status, and minutes/week of non-active transportation physical activity. Analyses were conducted in 2011. Results
Overall, 76% reported no active transportation. Compared with no active transportation, mean BMI was lower among individuals with low (-0.9, 95% CI= -1.4, -0.5) and high (-1.2, 95% CI= -1.7, -0.8) levels of active transportation. Mean waist circumference was lower in the low (-2.2 cm, 95% CI= -3.2, -1.2) and high (-3.1 cm, 95% CI= -4.3, -1.9) active transportation groups. The odds of hypertension were 24% lower (AOR=0.76, 95% CI=0.61, 0.94) and 31% lower (AOR=0.69, 95% CI=0.58, 0.83) among individuals with low and high levels of active transportation, respectively, compared with no active transportation. High active transportation was associated with 31% lower odds of diabetes (AOR=0.69, 95% CI=0.54, 0.88). Active transportation was not associated with high-density lipoprotein level. Conclusions
Active transportation was associated with more-favorable cardiovascular risk factor profiles, providing additional justification for infrastructure and policies that permit and encourage active transportation.

World Bank report examines likely impacts and risks associated with a 4 °C global warming within this centuryhttp://www.greencarcongress.com/2012/11/turndown-20121119.html 19 November 2012 A new report commissioned by the World Bank, and prepared by the Potsdam Institute for Climate Impact Research (PIK) and Climate Analytics, provideshttp://www.worldbank.org/en/news/2012/11/18/new-report-examines-risks-of-degree-hotter-world-by-end-of-century a snapshot of recent scientific literature and new analyses of likely impacts and risks that would be associated with a 4 °C global warming within this century. The report—Turn Down the Heat—attempts to outline a range of risks, focusing on developing countries and especially the poor. The report is not a comprehensive scientific assessment, the authors note; one such is slated to be forthcoming from the Intergovernmental Panel on Climate Change (IPCC) in 2013–14 in its Fifth Assessment Report. The World Bank report focused on developing countries, while recognizing that developed countries are also vulnerable and at serious risk of major damages from climate change.
