促使员工将平常的午餐改为低能量的替代品可能有助于使能量摄入量与公共卫生建议保持一致。我们测试了在有或没有身体活动卡路里当量 (PACE) 信息的情况下提供低能量交换对在假设的在线工作场所食堂预订的午餐能量的影响。英国就业成年人（n = 2,150）被邀请通过定制的在线平台从食堂预订午餐。他们按照 1:1:1 随机分配给：(i) 对照：不提供掉期； (ii) 提供较低能源互换； (iii) 提供带有 PACE 信息的低能量互换。主要结果是使用协方差分析并控制初始订购项目的能量含量订购的总能量。次要结果是掉期接受率和干预可接受性。参与者中 54% 为女性，平均年龄为 36.8 岁 (SD = 11.6)，BMI 为 26.3 (SD = 5.6)。与对照中订购的平均 819 kcal 能量相比，交换和交换 + PACE 干预措施均显着降低了订购的平均能量，分别为 47 kcal（95% CI：-82 至 -13，p = 0.003）和 66 kcal（95% CI：-100 至 -31，p< 0.001）。与仅提供掉期相比，掉期 + PACE干预导致掉期接受率显着提高（OR：1.63，95％CI：1.27至2.09，p < 0.001），但并没有显着减少订购的能量（-19kcal，95％CI：-53至16，p = 0.591）。大约 65% 和 16% 的干预参与者分别认为互换干预可接受和不可接受，其中互换 + PACE 干预被认为比仅互换更可接受（OR：1.32，95%CI：1.09 至 1.60，p< 0.004）。提供带有或不带有 PACE 信息的低能量交换实验性地减少了预订午餐的能量。这两种干预措施都有望减少购买的食品和饮料的能量。 试用注册如预测参考号：56358，22/01/21，https://aspredicted.org/pw2qr.pdf 在线版本包含补充材料，网址为 10.1186/s12966-022-01257-5。
Prompting employees to swap their usual lunches for lower-energy alternatives may help align energy intake with public health recommendations. We tested the effect of offering lower-energy swaps with and without physical activity calorie equivalent (PACE) information on the energy of lunches pre-ordered in an online hypothetical workplace canteen. UK employed adults (n = 2,150) were invited to hypothetically pre-order their lunch from the canteen through a custom-made online platform. They were randomised 1:1:1 to: (i) control: no swaps offered; (ii) lower-energy swaps offered; or (iii) lower-energy swaps offered with PACE information. The primary outcome was the total energy ordered using analysis of covariance and controlling for the energy content of the initial items ordered. Secondary outcomes were swap acceptance rate and intervention acceptability. Participants were 54% female, had a mean age of 36.8 (SD = 11.6) and a BMI of 26.3 (SD = 5.6). Compared with an average 819 kcal energy ordered in the control, both the swaps and swaps + PACE interventions significantly reduced average energy ordered by 47 kcal (95% CI: -82 to -13, p = 0.003) and 66 kcal (95% CI: -100 to -31, p < 0.001), respectively. Compared with offering swaps only, the swaps + PACE intervention led to significantly higher swap acceptance (OR: 1.63, 95% CI: 1.27 to 2.09, p < 0.001) but did not significantly reduce energy ordered (-19 kcal, 95% CI: -53 to 16, p = 0.591). About 65% and 16% of intervention participants found the swap interventions acceptable and unacceptable, respectively, with the swaps + PACE intervention being considered more acceptable than swaps only (OR: 1.32, 95%CI: 1.09 to 1.60, p < 0.004). Offering lower-energy swaps with or without PACE information reduced the energy of pre-ordered lunches experimentally. Both interventions hold promise for reducing the energy of purchased foods and drinks.
