Obesity, disordered eating, impulsivity, and stress represent distinct conditions, each with its own etiology and course and the potential to create profound ill-health in an individual. This study examined the interrelationship among these four health phenomena. Over a hundred college student participants completed an online health questionnaire including measures of impulsivity, perceived stress, and eating behavior. Negative urgency impulsivity was positively correlated with uncontrolled,...
Show moreObesity, disordered eating, impulsivity, and stress represent distinct conditions, each with its own etiology and course and the potential to create profound ill-health in an individual. This study examined the interrelationship among these four health phenomena. Over a hundred college student participants completed an online health questionnaire including measures of impulsivity, perceived stress, and eating behavior. Negative urgency impulsivity was positively correlated with uncontrolled, emotional, and binge eating while positive urgency impulsivity was positively correlated with uncontrolled eating. I hypothesized that five bivariate associations would be moderated by one or more variables. Nine two-way, between-subjects ANOVAs were conducted using median-splits to test the moderating effects of BMI, perceived stress, and impulsivity on disordered eating. Main effects for BMI level indicated that overweight/obese participants scored higher on emotional eating and uncontrolled eating than normal weight/underweight participants. An interaction between motor impulsivity and perceived stress explained variations in uncontrolled eating while an interaction between total impulsivity and perceived stress explained variations in binge eating. Limitations included a small educated, predominantly female, convenience sample. More men need to be included in future studies.
