Abstract
Policy makers have proposed implementing sugar-sweetened beverage (SSB) portion size cap policies as a public health initiative to curb SSB consumption and prevent obesity. Such a policy would eliminate larger portion-sizes of SSB and render the smaller-sized portion as the healthier, default option. This study evaluated the effects of an SSB portion-size cap on food and beverages purchased, consumed and caloric intake in three projects.
First, a systematic scoping review of obesity prevention efforts in young children described obesity prevention efforts in the United States. Next, a cross-sectional survey study examined the association between a 16 ounces (oz) SSB portion-size cap at the Barclays Center and SSBs oz and food calories purchased and consumed compared to Madison Square Garden, an arena with no SSB portion restrictions. The final study examined the impact of the SSB portion-size limit and offering free SSB refills on food, beverage and SSB calories purchased and consumed during a randomized controlled simulated restaurant dining experience.
The scoping review found a limited number of community and societal public health obesity policy initiatives targeting young children. Study two found the portion-size cap was associated with Barclays customers’ purchasing 2.24 fewer beverage oz (95% confidence interval [CI]= 4.19, .29, p=.024) and purchasing and consuming 11.03 (95% CI= 17.21, 4.86, p<.001) and 12.10 (95% CI= 18.42, 5.78, p<.001) fewer SSB oz, after adjusting for sex, age, BMI, ethnicity, race, marital status, education, and income without impacting food calories and arena-event experience. Study three did not find any association between an SSB portion-size restriction and food, beverage and SSB calories consumed during the simulated restaurant dinner meal but found that offering free SSB refills along with a 16 oz portion-sized SSB was associated with ordering a greater number of SSB compared with the current restaurant portion, purchase refill condition (0.66 vs. 0.40, p=.048).
This study provides preliminary real-world evidence of the effectiveness of an SSB portion-size cap in sporting arenas and suggests that SSB portion cap policies may be an effective public health strategy to reduce SSB consumption but may be limited by promotions such as free-refills.
