研究在一个以社区为基础的互联网行为项目中,增加小的、可变的经济激励或可选的小组会议是否能改善减肥效果。参与者(N=268)从塑造了罗得岛2012年,一个为期3个月的基于网络的社区健康倡议,被随机分配到:塑造+互联网行为计划(SI),塑造+互联网计划+激励(SII),或塑造+互联网计划+小组会议(SIG)。在3个月计划结束时,SII实现的体重减轻显著大于SI(SII:6.4% [5.1-7.7]; SI:4.2% [3.0-5.6]; P= 0.03); SIG中的体重减轻与其他两种情况无显著差异(SIG:5.8% [4.5-7.1],P ≥ 0.10)。然而,在12个月无治疗随访访视时,SII和SIG的体重减轻均大于SI(SII:3.1% [1.8-4.4]; SIG:4.5% [3.2-5.8]; SI:1.2% [-0.1-2.6]; P ≤.05)。在3个月(SII:34美元/公斤; SI:34美元/公斤; SIG:87美元/公斤)和12个月(SII:64美元/公斤; SI:140美元/公斤; SIG:113美元/公斤)时,SII是最具成本效益的方法。适度的经济激励措施在社区活动中增强了体重减轻,激励措施和可选的小组会议在随访期间改善了整体体重减轻结果。然而,使用财政奖励是最具成本效益的办法。
To examine whether adding either small, variable financial incentives or optional group sessions improves weight losses in a community-based, Internet behavioral program. Participants (N=268) from Shape Up Rhode Island 2012, a 3 month Web-based community wellness initiative, were randomized to: Shape Up+Internet behavioral program (SI), Shape Up+Internet program+Incentives (SII), or Shape Up+Internet program+Group sessions (SIG). At the end of the 3 month program, SII achieved significantly greater weight losses than SI (SII:6.4% [5.1-7.7]; SI:4.2% [3.0-5.6]; P=.03); weight losses in SIG were not significantly different from the other two conditions (SIG: 5.8% [4.5-7.1], P’s≥.10). However, at the 12 month no treatment follow-up visit, both SII and SIG had greater weight losses than SI (SII: 3.1% [1.8-4.4]; SIG: 4.5% [3.2-5.8]; SI: 1.2% [-0.1-2.6]; P’s≤.05). SII was the most cost-effective approach at both 3 (SII: $34/kg; SI: $34/kg; SIG: $87/kg) and 12 months (SII: $64/kg; SI: $140/kg; SIG: $113/kg). Modest financial incentives enhance weight losses during a community campaign and both incentives and optional group meetings improved overall weight loss outcomes during the follow-up period. However, the use of the financial incentives is the most cost-effective approach.
