ABSTRACT
Objective
Some versions of restaurant menu labelling legislation do not require energy information to be posted on menus for drive-through lanes. The present study was designed to quantify the number of customers who purchase fast food through drive-in windows as a means of informing legislative labelling efforts.Design: This was an observational study.
Setting
The study took place at two McDonald’s and Burger King restaurants, and single Dairy Queen, Kentucky Fried Chicken, Taco Bell and Wendy’s restaurants. Subjects: The number of customers entering the chain restaurants and purchasing food via the drive-through lane were recorded. A total of 3549 patrons were observed.
Results
The percentage of customers who made their purchases at drive-throughs was fifty-seven. The overall average (57%) is likely a conservative estimate because some fast-food restaurants have late-night hours when only the drive- throughs are open.
Conclusions
Since nearly six in ten customers purchase food via the drive- through lanes, menu labelling legislation should mandate the inclusion of menu labels on drive-through menu boards to maximise the impact of this public health intervention.
