Background

College students encounter challenges in managing their weight. The COVID-19 pandemic exacerbated the problem. The purpose of this study was to determine the effect of a motivational interviewing (MI) intervention compared to online education (control) on body composition and self-determination theory constructs among college students with overweight.

Methods

This was a randomized clinical trial of 40 college students comparing an MI versus a control group. The MI group received monthly interviews: three face-to-face interviews before the pandemic, and three video chat interviews after the outbreak of COVID-19 spanning a total of 6 months. The control group received 6 monthly education modules. Body composition was measured by the iDexa, and self-determination theory (SDT) variables were assessed with surveys.

Results

Mixed analysis of variance [ANOVAs] from pre-post revealed significant changes in fat mass (P=0.03, η²=0.22), lean mass (P<0.05, η²=00.18), body fat percentage (P<0.01, η²=0.37), autonomy (P<0.01, η²=0.38), relatedness (P<0.01, η²=0.41), amotivation (P=0.01, η²=0.29), external regulation (P=0.02, η²=0.23), identified regulation (P=0.02, η²=0.25), integrated regulation (P<0.00, η²=0.49), and intrinsic regulation (P=0.01, η²=0.27).

Conclusions

In this exploratory analysis, MI demonstrated a positive trend in body composition maintenance when compared to online education among overweight college students during a national pandemic. Future studies utilizing MI would enhance the literature by further investigating the relationship between MI and SDT and measuring body composition.
