Abstract

Objective: Over the past several decades, increase in SSB consumption has coincided with increasing rates of obesity. This study evaluated the association between SSB consumption and BMI. Methods: FFQ data from NHANES 2003-2004 was used to examine 100% orange juice, sugar-sweetened fruit drinks, soft drinks, and other beverage consumption frequency vs. mean BMI. ANOVA, relative risk, and linear regression analyses were done. Results: ANOVA found significant differences in mean BMI across consumption frequencies for orange juice (p=.001), sugar-sweetened fruit drinks (p<.001), and soft drinks (p<.001). Increased risk of being obese was associated with increasing consumption frequency for orange juice (RR=1.282), sugar-sweetened fruit drinks (RR=1.417), and soft drinks (RR=1.749). Multiple linear regression found significant positive associations between mean BMI and sugar-sweetened fruit drinks (b=.056, p=.004) and soft drinks (b=.134, p=.001). Conclusion: This study found that mean BMI was positively associated with certain beverage consumption frequency (sugar-sweetened fruit drinks, soft drinks consumed during summer, soft drinks consumed during rest of year), but not others (100% orange juice). Fewer significant results were found when confounding variables were controlled. Drinking soft drinks or sugar-sweetened fruit drinks increased the risk of obesity more than drinking natural fruit juices.
