Technological advancements in the past decades have improved dietary intake and physical activity measurements. This report reviews current developments in dietary intake and physical activity assessment in youth. Dietary intake assessment has relied predominantly on self-report or image-based methods to measure key aspects of dietary intake (e.g., food types, portion size, eating occasion), which are prone to notable methodologic (e.g., recall bias) and logistic (e.g., participant and researcher burden) challenges. Although there have been improvements in automatic eating detection, artificial intelligence, and sensor-based technologies, participant input is often needed to verify food categories and portions. Current physical activity assessment methods, including self-report, direct observation, and wearable devices, provide researchers with reliable estimations for energy expenditure and bodily movement. Recent developments in algorithms that incorporate signals from multiple sensors and technology-augmented self-reporting methods have shown preliminary efficacy in measuring specific types of activity patterns and relevant contextual information. However, challenges in detecting resistance (e.g., in resistance training, weight lifting), prolonged physical activity monitoring, and algorithm (non)equivalence remain to be addressed. In summary, although dietary intake assessment methods have yet to achieve the same validity and reliability as physical activity measurement, recent developments in wearable technologies in both arenas have the potential to improve current assessment methods. ⋯ This article is part of a theme issue entitled Innovative Tools for Assessing Diet and Physical Activity for Health Promotion, which is sponsored by the North American branch of the International Life Sciences Institute.

Electronic cigarettes (e-cigarettes) are promoted as a less risky alternative to conventional cigarettes and have grown in popularity. Experimental and clinical evidence suggests that they could increase the risk of myocardial infarction. ⋯ Daily e-cigarette use, adjusted for smoking conventional cigarettes as well as other risk factors, is associated with increased risk of myocardial infarction.

Interventions that reduce access to highly lethal and commonly used methods of suicide (e.g., limiting firearm access) are considered essential elements of effective suicide prevention programs. Scant epidemiologic data are available to inform such efforts among Veterans. The aim of this study is to describe firearm storage practices and correlates of those practices among a nationally representative sample of U.S. Veteran firearm owners. ⋯ Storing a firearm loaded and unlocked is common among Veterans. Storage practices are strongly related to reasons for ownership and potentially malleable perceptions including beliefs about firearm-related risks. Suicide prevention initiatives among Veterans should incorporate communication strategies that address common misperceptions about household firearm risk and whether safe storage practices may better align with reasons most Veterans own firearms (i.e., safety)-especially when someone in their home is at increased risk for suicide.
