BACKGROUND
Unhealthy diet including consumption of high amounts of sugar-sweetened beverages is a key modifiable risk factor for obesity and NCDs which begin in childhood and adolescence. The study aimed to compare the effect of gain frame vs. loss frame messages on SSBs consumption intention and behavior of high school boy students.
METHODS
In this quasi-experimental study, 270 students from three boy's high schools were selected through a multistage random sampling. Data collection was done through a 15 items self-reported questionnaire before and two months after the intervention. Each of the two intervention groups received one of the two types of gain frame or loss frame designed pamphlets inspired with extended parallel process model. The control group received no pamphlet.
RESULTS
In control, GFM and LFM groups 91, 86 and 89 students participated in the study, respectively. After the intervention, significant differences were observed in perceived efficacy and threat of the GFM group and perceived efficacy, threat and intention in the LFM group compared with before the intervention. The GFM group had higher perceived self-efficacy than the control group and lower perceived severity than the LFM group. Intention to consume SSBs reduced significantly in LFM group, compared with the control group.
CONCLUSIONS
A combination of LFM and GFM messages could more effectively lead to nutritional behavior change regarding the consumption of SSBs. Results help to design messages for educational programs and nutritional campaigns.
背景
不健康的饮食，包括摄入大量含糖饮料，是肥胖和非传染性疾病的一个主要可改变风险因素，这些疾病始于儿童和青少年时期。本研究旨在比较增益框架与损失框架信息对高中男生 SSB 消费意愿和行为的影响。
方法
在这项准实验研究中，通过多阶段随机抽样，从三所男校中选取了 270 名学生。在干预前和干预后两个月，通过一份 15 项自我报告问卷收集数据。两个干预组分别收到了两种类型的增益框架或损失框架设计的小册子，这些小册子是受扩展平行过程模型启发而设计的。对照组没有收到小册子。
结果
在对照组、GFM 组和 LFM 组中，分别有 91、86 和 89 名学生参与了研究。干预后，与干预前相比，GFM 组的感知效能和威胁以及 LFM 组的感知效能、威胁和意图均有显著差异。GFM 组的感知自我效能感高于对照组，感知严重程度低于 LFM 组。与对照组相比，LFM 组 SSB 的消费意愿显著降低。
结论
增益框架与损失框架信息的结合可以更有效地促进 SSB 消费的营养行为改变。研究结果有助于为教育计划和营养运动设计信息。
