摘要

研究目的本研究的目的是评估纽约市超市对水果蔬菜(F&V)和无热量饮料打折后的购买量、摄入量和体重:进行了一项为期 16 周的随机对照试验,基线期为 4 周,干预期为 8 周,果蔬和无热量饮料打五折,后续期为 4 周。购买情况通过会员卡进行跟踪,摄入量通过 24 小时膳食回顾进行跟踪。在五次上门访问中测量了体重:对 67 名参与者的数据进行了分析(实验组 38 人;对照组 29 人)。实验组每周购买的食品和饮料以及非热量饮料多于对照组(平均差异[SD]为 4.64 美元[1.44 美元],P餐饮和非热量饮料的半价优惠促进了餐饮和非热量饮料购买量和摄入量的增加,并促使体重减轻。

Effects of discounting fruits, vegetables, and noncaloric beverages in New York City supermarkets on purchasing, intake, and weight

Objective

The objective of this study was to assess purchasing, intake, and weight after discounting fruits and vegetables (F&V) and noncaloric beverages in New York City supermarkets.

Methods

A 16-week randomized controlled trial was conducted with a 4-week baseline, an 8-week intervention with 50% discounts on F&V and noncaloric beverages, and a 4-week follow-up. Purchasing was tracked via loyalty cards, and intake was tracked via 24-h dietary recalls. Weights were measured at five in-person visits.

Results

Data from 67 participants were analyzed (38 in the experimental group; 29 in the control group). F&V and noncaloric beverage weekly purchasing was greater in the experimental than the control group (mean difference [SD], $4.64 [$1.44], p < 0.0001; $0.53 [$0.39], p = 0.008) during intervention, with F&V purchasing remaining greater in the experimental versus control group during follow-up (p = 0.005). F&V intake was greater for the experimental than the control group during intervention (142 [105] g/day; p = 0.009) and follow-up (p = 0.001). Although no difference in noncaloric beverage consumption was observed between groups, there was lower alcohol intake in the experimental than the control group during follow-up (−85.8 [60.2] g/day; p = 0.004). The experimental group lost weight compared with the control group (−1.33 [0.92] kg; p = 0.006 intervention and p = 0.106 follow-up). No differences in nutrient composition or high energy-dense product consumption were found.

Conclusions

A 50% discount on F&V and noncaloric beverages promoted increased purchasing and intake of F&V and induced weight loss.
