Over the past decade, the body of research linking energy balance to the incidence, development, progression, and treatment of cancer has grown substantially. No prior NIH portfolio analyses have focused on energy balance within one institute. This portfolio analysis describes the growth of National Cancer Institute (NCI) grant research on energy balance-related conditions and behaviors from 2004 to 2010 following the release of an NCI research priority statement in 2003 on energy balance and cancer-related research. ⋯ Breast cancer was the most commonly studied cancer. Inclusion of minorities rose, and funding specific to cancer survivors more than doubled. From FY2004 to FY2010, NCI's investment in energy balance and related health behavior research showed growth in funding and diversity of mechanisms, topics, and disciplines-growth that reflects new directions in this field.

In 2009, the quadrivalent human papillomavirus (HPV) vaccine was licensed by the U.S. Food and Drug Administration for use in men/boys aged 9-26 years. In 2009, the Advisory Committee on Immunization Practices (ACIP) provided a permissive recommendation allowing HPV vaccine administration to this group. ⋯ HPV vaccination initiation among men aged 18-26 years in 2010 was low. HPV and HPV vaccine awareness were also low, and messages in this area directed to men are needed. Since ACIP published a recommendation for routine use of HPV4 among men/boys in December 2011, continued monitoring of HPV vaccination uptake among men aged 18-26 years is useful for evaluating the vaccination campaigns, and planning and implementing strategies to increase coverage.

Sedentary behavior is associated with increased risk of chronic disease and sedentary behavior is increasing among adolescents. Data on changes in sedentary behavior in developing countries are limited. ⋯ Nonschool sedentary behavior increased among Vietnamese adolescents with age. The largest increase was in recreational screen time (28%), which would be the most obvious target for preventive health strategies.

Neighborhood designs often relate to physical activity and to BMI. ⋯ Although walking/biking to work is rare in the U.S., greater proportions of such workers in neighborhoods relate to lower weight and higher MVPA. Bikeability merits greater attention as a modifiable activity-friendliness factor, particularly for men.

Studies have shown relationships between important health outcomes and sedentary behavior, independent of physical activity. There are known errors in tools employed to assess sedentary behavior. Studies of accelerometers have been limited to laboratory environments. ⋯ Researchers should be aware of the strengths and weaknesses of the 100-cpm accelerometer cutpoint for identifying sedentary behavior. The SenseCam may be a useful tool in free-living conditions to better understand health behaviors such as sitting.
