This scoping review examines the literature as it relates to autonomous vehicles and impact on movement behavior (i.e., physical activity, sedentary behavior, and sleep) or mode choice (e.g., public transit), beliefs about movement behavior or mode choice, or impact on environments that may influence movement behavior or mode choice. ⋯ Though no experimental or longitudinal studies have been published to date, the available research suggests that autonomous vehicles will impact aspects of mode choice and the built environment of people residing in much of the developed world, resulting in reduced walking and more sitting.

Prior studies have identified associations between obesity and numerous conditions that increase risks for chronic pain. However, the impact of obesity on prescription opioid use is not well known. This study investigates the association between obesity and incidence of long-term prescription opioid use. ⋯ These findings suggest that obesity has contributed to prescription opioid use in the U.S. Future investments in chronic pain reduction may benefit from increased integration with obesity prevention and treatment.

Fast food restaurants, including top burger chains, have reduced calorie content of some menu items in recent years. However, the extent to which the nutrition profile of restaurant menus is changing over time is unknown. ⋯ At large chain burger restaurants, most items were unhealthy, and the overall nutrition profile of menus remained unchanged from 2012 to 2016. Future research should examine the nutrition profile of restaurant menus in a larger, more diverse sample of restaurants over a longer timeframe and examine whether results are robust when other measures of nutritional quality are used.
