摘要：We surveyed 7318 customers from 275 randomly selected restaurants of 11 fast food chains. Participants purchased a mean of 827 calories, with 34% purchasing 1000 calories or more. Unlike other chains, Subway posted calorie information at point of purchase and its patrons more often reported seeing calorie infomation than patrons of other chains (32% vs 4%; P <.001); Subway patrons who saw calorie information purchased 52 fewer calories than did other Subway patrons ( P <.01). Fast-food chains should display calorie information prominently at point of purchase, where it can be seen and used to inform purchases. Rates of obesity and associated health complications are increasing rapidly in the United States. Fast food is typically calorie-dense, and frequent intake of fast food has been associated with increased calorie intake, weight gain, overweight, and obesity. 1 – 5 Despite this, fast-food restaurants are not required to provide nutritional information, and, at the time of this study, only 1 large fast-food restaurant chain in New York City (Subway) lists calorie information at the point of purchase. Various state and local governments, including New York City’s, are considering requiring restaurants to post calorie information prominently. We conducted a large cross-sectional survey to characterize patrons’ fast-food purchases and their observation and use of calorie information.
