BackgroundLittle is known about the decision-making process of adults who choose to eat at fast-food restaurants. Impulsivity is the concept that individuals value immediate rewards and disregard future costs.ObjectiveTo determine the association between impulsivity and consumption of fast food among employed adults and to explore their reasons for eating fast food.DesignA cross-sectional, online survey was conducted; participants were recruited using a mass electronic mailing.Participants/settingFour hundred seventy-eight adults employed in a university setting completed the survey.Main outcome measuresThe association between frequency of fast-food consumption and impulsivity was assessed. Impulsivity is assessed by the area under the delay discounting curve (AUC). The AUC is estimated by using a binary choice delay discounting task incorporating hypothetical monetary rewards. Greater AUC reflects lower impulsivity.Statistical analyses performedAnalysis of variance, Student’s t tests, and Pearson correlation coefficients were used to measure unadjusted associations among demographic variables, fast-food consumption, and AUC. Linear regression was used to assess whether AUC was a significant predictor of having consumed fast food in the past 7 days, controlling for age, total household income, and education.ResultsThe majority (67%) of the participants reported eating one or more meals from a fast-food restaurant or pizza place in the past 7 days. The mean number of meals was 2.8±2.5 per week among those who reported eating at a fast-food restaurant or pizza place. Both fast-food consumption and body mass index (BMI) were correlated with greater impulsivity. Controlling for age, total household income, and education level, fast-food consumption was negatively related to AUC (P=0.017). The most commonly reported reasons for consuming fast food were convenience and to socialize.ConclusionsThese findings indicate that greater impulsivity was associated with greater fast-food consumption. Successful efforts to encourage healthful dietary behaviors might emphasize methods to overcome impulsivity, such as reward substitution and precommitment.
