Technologic advances mean automated, wearable cameras are now feasible for investigating health behaviors in a public health context. This paper attempts to identify and discuss the ethical implications of such research, in relation to existing guidelines for ethical research in traditional visual methodologies. ⋯ This paper attempts to formalize the protection of all according to best ethical principles through the development of an ethical framework. Respect for autonomy, through appropriate approaches to informed consent and adequate privacy and confidentiality controls, allows for ethical research, which has the potential to confer substantial benefits on the field of health behavior research.

Video game-based exercise, Latino children's physical health, and academic achievement.
There is a paucity of research investigating the effects of innovative physical activity programs on physical health and academic performance in the Latino population. ⋯ The DDR-based exercise intervention improved children's cardiorespiratory endurance and math scores over time. Professionals should consider integrating exergaming at schools to achieve the goals of promoting a physically active lifestyle and enhancing academic success among Latino children.

Fighting childhood obesity has become a key policy focus. The role of community-based interventions to promote physical activity is an important part of an overall strategy to increase physical activity for youth. ⋯ These findings point to the promise of relying on existing community resources in the fight against childhood obesity. Fitness-focused afterschool programs will need to ensure that the highest-risk children--including those who are Latino and low-income--are served.

Participation in physical activity brings health benefits for adolescents. However, limited data are available on the percentage of U.S. adolescents who engage in levels of aerobic and muscle-strengthening activities recommended in the 2008 Physical Activity Guidelines for Americans (2008 Guidelines). ⋯ Less than 20% of adolescents reported engaging in recommended levels of both aerobic and muscle-strengthening activities.

Food diaries are commonly used to assess individual dietary intake in both the general and sporting populations. Despite the widespread use of such diaries, evidence suggests that individuals' self-reported energy intake frequently and substantially underestimate true energy intake. ⋯ Results from this first-generation study suggest that a more accurate estimate of total energy intake is provided when combining the use of a conventional food diary and a SenseCam. Additional information on portion size, forgotten foods, leftovers, and brand names can be obtained by using this novel sensing technology in conjunction with the diary, with improved dietary assessment a potential outcome.
