“…Mobile vending might exacerbate demographic, diet, and diet-related health disparities in urban neighborhoods, but the extent of their negative contributions to food-environment healthfulness may vary by weather and season. From a positive standpoint, mobile vending could improve healthy-food availability in neighborhoods (Abusabha et al, 2011; Jennings et al, 2012; Leggat et al, 2012; Marx, 2012; Tester et al, 2012; Widener et al, 2012) and might provide a viable alternative to more-resource-intensive strategies for food-environment modification focused on ‘fixed’ food sources (e.g., restricting fast-food development,(Babey et al, 2011; Keener, July 2009) attracting new grocers,(Babey et al, 2011; Centers for Disease Control, 2011; Institute of Medicine, 2009; Keener, July 2009) redesigning small stores,(Bodor et al, 2010; Centers for Disease Control, 2011; Dannefer et al, 2012; Gittelsohn et al, 2010; Institute of Medicine, 2009; Keener, July 2009; O'Malley et al, 2013; Raja, 2008) or promoting supermarkets (Centers for Disease Control, 2011; Giang et al, 2008; Institute of Medicine, 2009; Keener, July 2009; Morland et al, 2002; Pothunkuchi, 2005)). Future research on mobile vending should explore availability, quality, and price of mobile foods compared to foods from adjacent store-front businesses, and determine customer demographics, purchasing, and consumption patterns.…”
