Healthy Eating in College Students: 24-Hour Dietary Recall and the Theory of Planned Behavior

The transition to college is marked by poorer eating behaviors. The Theory of planned behavior (TPB) represents a promising tool for predicting eating behaviors through the examination of attitudes (ATT), subjective norms (SN), perceived behavioral control (PBC), and intention (INT). Despite prior application of the TPB, there exist several key methodological issues in the literature addressing eating behaviors. The present study utilized an enhanced dietary assessment methodology, the ASA24 dietary recall, and a short-term prospective design to assess the healthy eating behaviors of emerging adults in college. Dietary recalls of 68 participants (average age = 20.76 years; 70.6% female; 70.6% non-Hispanic, 48.5% White, 22.10% Black/African American, 13.20% Asian) were analyzed using the Healthy Eating Index (HEI)-2010 scoring system. Results revealed that very few college students are meeting recommended dietary guidelines. Linear regression indicated that the indirect TPB variables (ATT, SN, and PBC) were related to INT (F[3,64] = 19.67, p < .001), although SN did not account for unique variance. Further, the direct TPB variables (INT and PBC) were related to HEI-2010 scores (F[2,65] = 4.00, p = .023); however, only PBC accounted for significant variance. Overall, findings suggest that more favorable attitudes relate to intention, but only perceived behavioral control consistently relates to actual healthy eating behavior.
