目的探讨两种营养干预措施对食品、饮料和补充剂摄入与体重的影响。设计：随机对照试验。五家专业的养老院设施。参与者：有营养补充订单的长期居住居民（N = 154）。参与者被随机分为常规护理对照组、口服液营养补充剂（ONS）干预组和零食干预组。研究人员提供ONS，根据订单或各种零食和饮料，每天两次的正餐之间，每周5天，为期24周，并协助促进消费。测量在24周的干预期间，研究人员在基线和每月独立称重居民。使用标准化观察和称量摄入程序，在基线和干预期间每月两天对居民食品、饮料和补充剂摄入量以及工作人员提供帮助的时间进行评估。结果：与对照组相比，ONS干预组平均每天多摄入265卡路里，而零食干预组平均每天多摄入303卡路里。提供每次干预所需的工作人员时间平均为每人11分钟和14分钟，每次提供ONS和零食，常规护理所需的工作人员时间为3分钟。两种干预措施在增加热量摄入方面都具有成本效益，但两种干预措施对体重都没有显著影响，尽管有积极的趋势。结论口服液营养补充剂和零食提供在辅助促进消耗和多种选择的情况下可以有效促进热量摄入，但两种干预措施都不会导致体重显著增加。
ObjectivesTo determine the cost-effectiveness of two nutrition interventions on food, beverage, and supplement intake and body weight.DesignRandomized, controlled trial.SettingFive skilled nursing home facilities.ParticipantsLong-stay residents with orders for nutrition supplementation (N = 154).InterventionParticipants were randomized into a usual care control group, an oral liquid nutrition supplement (ONS) intervention group, or a snack intervention group. Research staff provided ONS, according to orders or a variety of snack foods and beverages twice per day between meals, 5 days per week for 24 weeks and assistance to promote consumption.MeasurementsResearch staff independently weighed residents at baseline and monthly during the 24-week intervention. Resident food, beverage and supplement intake and the amount of staff time spent providing assistance were assessed for 2 days at baseline and 2 days per month during the intervention using standardized observation and weighed intake procedures.ResultsThe ONS intervention group took in an average of 265 calories more per day and the snack intervention group an average of 303 calories more per day than the control group. Staff time required to provide each intervention averaged 11 and 14 minutes per person per offer for ONS and snacks, respectively, and 3 minutes for usual care. Both interventions were cost-effective in increasing caloric intake, but neither intervention had a significant effect on body weight, despite positive trends.ConclusionOral liquid nutrition supplements and snack offers were efficacious in promoting caloric intake when coupled with assistance to promote consumption and a variety of options, but neither intervention resulted in significant weight gain.
