Abstract
OBJECTIVE: Investigate attention to Nutrition Facts Labels (NFLs) with numeric only vs both numeric and activity-equivalent calorie information, and attitudes toward activity-equivalent calories. DESIGN: An eye-tracking camera monitored participants' viewing of NFLs for 64 packaged foods with either standard NFLs or modified NFLs. Participants self-reported demographic information and diet-related attitudes and behaviors. SETTING:Participants came to the Behavioral Medicine Lab at Colorado State University in spring, 2015. PARTICIPANTS: The researchers randomized 234 participants to view NFLs with numeric calorie information only (n = 108) ornumeric and activity-equivalent calorie information (n = 126). MAIN OUTCOME MEASURE(S): Attention to and attitudes about activity-equivalent calorie information. ANALYSIS: Differences by experimental condition and weight loss intention (overall and within experimental condition) were assessed using t tests and Pearson's chi-square tests of independence. RESULTS: Overall, participants viewed numeric calorie information on 20% of NFLs for 249 ms. Participants in the modified NFL condition viewed activity-equivalent information on 17% of NFLs for 231 ms. Most participants indicated that activity-equivalent calorie information would help them decide whether to eat a food (69%) and that they preferred both numeric and activity-equivalent calorie information on NFLs (70%). CONCLUSIONS AND IMPLICATIONS: Participants used activity-equivalent calorie information on NFLs and found this information helpful for making food decisions.
