Abstract (Summary)

Background: High-fructose corn syrup is widely used as a sweetener in the beverage industry. High consumption of fructose was found to be associated with increased de novo lipogenesis and increased triglyceride deposition in the liver and adipose tissues. Some studies found that high consumption of sugar-sweetened beverages (SSB) was correlated with increased BMI and body adiposity. No studies to date have examined the association between college-level nutrition education and habitual SSB consumption.

Objective: The purpose of this study was to determine the correlations between habitual SSB consumption and body fat mass, percent body fat, waist circumference and BMI in college students. In addition, this study examined the difference in habitual SSB consumption between nutrition and dietetics majors and non-nutrition and dietetics majors.

Design: This cross-sectional descriptive study recruited 155 college students by convenience sampling at a university in the US Midwest region. Seventy-three were nutrition and dietetics students (graduating seniors and graduate students) and 83 were non-nutrition and dietetics students with any class standing. After the participants completed a beverage intake questionnaire, their height was measured using a wall-mounted stadiometer, their weight and body composition were assessed using a Tanita scale, and waist circumference was measured using a cloth tape.

Main outcome measures: Body fat mass, percent body fat, waist circumference, BMI and self-report habitual SSB consumption.

Statistical analyses performed: Pearson correlations were used to determine the correlations between habitual SSB consumption and body fat mass, percent body fat, waist circumference and BMI. An independent t test was used to determine if there was a mean difference in habitual SSB consumption between nutrition and dietetics and non-nutrition and dietetics students. Multiple regression analyses were completed post hoc to find out if there were any predictors of body adiposity and habitual SSB consumption.

Results: There was no significant correlation between habitual SSB consumption and body fat mass (r = 0.002, p = 0.98), percent body fat (r = -0.078, p = 0.34) and BMI (r = 0.102, p = 0.21). There was a significant positive correlation between habitual SSB consumption and waist circumference (r = 0.169, p = 0.04). Non-nutrition and dietetics majors consumed significantly more SSB than nutrition and dietetics majors, 20.5 ± 20.1 fluid ounces (293.3 ± 301.8 kcal) vs. 7.8 ± 9.0 fluid ounces (111.4 ± 142.6 kcal), t(118) = -4.879, p < 0.001. The results of multiple regression analyses suggested that females and students who wanted to lose weight were more likely to have high body fat mass. Older students, females and students who wanted to lose weight were more likely to have high percent body fat. Males, non-Hispanic Whites or students who wanted to lose weight were more likely to have high waist circumference. Males and students who wanted to lose weight were more likely to have high BMI. Non-nutrition and dietetics major was a predictor of high habitual SSB consumption.

Conclusion: Results suggested that a high habitual SSB consumption was correlated with a large waist circumference (an indicator of central obesity) and college-level nutrition education might help students make better beverage choices and reduce habitual SSB consumption. Further research with a large and diverse sample is warranted to investigate factors in addition to SSB consumption that may contribute to body adiposity, such as demographic characteristics, lifestyle factors, eating pattern and portion sizes.
