The Associations of Romantic Relationships, Eating Out Habits, and Alcohol Consumption in College Freshman Over Time

Background: While a growing body of literature acknowledges the role that close relationships have on nutrition outcomes, little research has assessed how significant others impact health during youth. This study assessed how being in a relationship during freshman year is associated with fast food consumption, restaurant meals, and alcohol intake.Methods: The current study is a secondary analysis from SPARC (Social impact of Physical Activity and nutRition in College), a longitudinal study of nutrition and weight outcomes among college freshman. Participants (n=535; 73% female; 50% non-white) completed web-based surveys during the 2015-2016 academic year at two different time points: August 2015 (Time 1) and November 2015 (Time 2). Mixed generalized logistic regression, adjusted for participant sociodemographic and clustering of students within residence halls, examined the association between fast food consumption, restaurant meals, and alcohol intake at Time 2, after controlling for Time 1 relationship status and Time 1 eating out, and alcohol intake. Results: At Time 1, 34% of participants were in a relationship, 23% of participants reported fast food consumption >2 days/week and 31% reported restaurant meals >1 day/week, and 43% reported weekly alcohol intake. Participants in a relationship at Time 1 were significantly more likely to eat in a restaurant at Time 2, after controlling for Time 1 restaurant use (OR= 1.78, p=0.009). No association was observed with relationship status and fast food consumption (OR=1.36, p=0.226), or alcohol consumption (OR=0.67, p=0.096). Conclusions: Findings suggest romantic relationships are associated with greater restaurant use in college freshman, but none of the other assessed behaviors. Future research is needed to assess the extent to which being in a relationship influences eating behavior among college freshman, and how it may relate to weight changes.
