Background Environmental and behavioral interventions hold promise to reduce sugar-sweetened beverage (SSBs) consumption. Purpose To test, among frequent SSB consumers, whether motivations to consume SSBs moderated the effects of (a) a workplace SSB sales ban (environmental intervention) alone, and (b) a “brief motivational intervention” (BI) in addition to the sales ban, on changes in SSB consumption. Methods We assessed whether (1) baseline motivations to consume SSBs (craving, psychological stress, or taste enjoyment) impacted changes in daily SSB consumption at 6-month follow-up among frequent (>12oz of SSBs/day) SSB consumers (N = 214); (2) participants randomized to the BI (n = 109) versus to the sales ban only (n = 105) reported greater reductions in SSB consumption at follow-up; and (3) motivations to consume SSBs moderated any changes in SSB consumption. Results In response to the sales ban alone, individuals with stronger SSB cravings (+1 SD) at baseline showed significantly smaller reductions in daily SSB consumption at 6-month follow-up relative to individuals with weaker (−1 SD) SSB cravings (2.5 oz vs. 22.5 oz), p < .01. Receiving the BI significantly increased reductions for those with stronger SSB cravings: Among individuals with stronger cravings, those who received the BI evidenced significantly greater reductions in daily SSB consumption [M(SE) = −19.2 (2.74) oz] than those who did not [M(SE) = −2.5 (2.3) oz, p < .001], a difference of 16.72 oz. Conclusions Frequent SSB consumers with stronger SSB cravings report minimal reductions in daily SSB consumption with a sales ban only, but report greater reductions if they also receive a motivational intervention. Future multilevel interventions for institutions should consider both environmental and individualized multi-level interventions. Clinical Trial information NCT02585336.

一个简短的激励干预以不同的方式减少含糖饮料 (SSB) 的消费

背景 环境和行为干预有望减少含糖饮料 (SSB) 的消费。目的 测试在频繁使用 SSB 的消费者中，消费 SSB 的动机是否会缓和（a）工作场所 SSB 销售禁令（环境干预）和（b）除销售外的“简短动机干预”（BI）的影响。禁止，对 SSB 消费的变化。方法 我们评估了（1）消费 SSB 的基线动机（渴望、心理压力或味觉享受）是否会影响在 6 个月的随访中，SSB 频繁（>12 盎司/天）SSB 消费者（N = 214); (2) 随机分配到 BI (n = 109) 与仅接受销售禁令 (n = 105) 的参与者报告在随访中 SSB 消费量减少了更多；(3) 消费 SSB 的动机缓和了 SSB 消费的任何变化。结果 仅针对销售禁令，基线时对 SSB 渴望更强 (+1 SD) 的个体在 6 个月的随访中显示出相对于对 SSB 渴望较弱 (-1 SD) 的个体 (2.5 oz 与 22.5 oz)，p < .01. 接受 BI 显着增加了对 SSB 渴望更强烈的人的减少：在渴望更强烈的人中，接受 BI 的人的每日 SSB 消耗量显着减少 [M(SE) = -19.2 (2.74) oz] 比那些没有[M(SE) = -2.5 (2.3) 盎司，p < .001]，相差 16.72 盎司。结论 具有强烈 SSB 渴望的频繁 SSB 消费者报告说，仅在销售禁令的情况下，每日 SSB 消费量的减少幅度很小，但如果他们也接受了激励干预，他们会报告更大的减少。未来对机构的多层次干预应考虑环境和个性化的多层次干预。临床试验信息 NCT02585336。
