The FAN Social Marketing program was developed to improve dietary and physical activity habits of families with children in Ticino, Switzerland. The aim of this study was to examine if the effects of the program on children's food intake differed by intervention group.
Effects of the FAN program were tested through a Randomized Controlled Trial. The program lasted 8 weeks, during which participants received tailored communication about nutrition and physical activity. Families were randomly allocated to one of three groups, where the parent received the intervention by the Web (G1), Web + e-mail (G2) or Web + SMS (G3). Children in all groups received tailored print letters by post. Children's food consumption was assessed at baseline and immediate post intervention using a 7-day food diary. Generalized linear mixed models with child as a random effect and with time, treatment group, and the time by treatment interaction as fixed effects were used to test the impact of the intervention.
Analyses were conducted with a sample of 608 children. After participating in FAN the marginal means of daily consumption of fruit changed from 0.95 to 1.12 in G1, from 0.82 to 0.94 in G2, and from 0.93 to 1.18 in G3. The margins of the daily consumption of sweets decreased in each group (1.67 to 1.56 in G1, 1.71 to 1.49 in G2, and 1.72 to 1.62 in G3). The change in vegetable consumption observed from pre to post intervention in G3 (from 1.13 to 1.21) was significantly different from that observed in G1 (from 1.21 to 1.17).
A well-designed Web-based Social Marketing intervention complemented with print letters can help improve children's consumption of water, fruit, soft drinks, and sweets. The use of SMS to support greater behavior change, in addition to Web-based communication, resulted only in a small significant positive change for vegetables, while the use of e-mail in addition to Web did not result in any significant difference.
The trial was retrospectively registered in the ISRCTN registry (ID ISRCTN48730279 ).
FAN 社会营销计划旨在改善瑞士提契诺州有孩子的家庭的饮食和体育活动习惯。本研究的目的是检验该计划对儿童食物摄入量的影响是否因干预组而异。
通过随机对照试验检验 FAN 计划的效果。该计划持续 8 周，在此期间，参与者收到有关营养和体育活动的个性化沟通。家庭被随机分配到三个组中的一个，其中父母通过网络（G1）、网络+电子邮件（G2）或网络+短信（G3）接受干预。所有组的儿童都通过邮寄收到个性化的印刷信件。使用 7 天食物日记在基线和即时干预后评估儿童的食物消耗。使用具有儿童为随机效应且具有时间、治疗组和时间与治疗组交互作为固定效应的广义线性混合模型来检验干预的影响。
对 608 名儿童的样本进行了分析。在参与 FAN 后，G1 组每天水果摄入量的边际均值从 0.95 增加到 1.12，G2 组从 0.82 增加到 0.94，G3 组从 0.93 增加到 1.18。每组的甜食每日摄入量都有所减少（G1 组从 1.67 减少到 1.56，G2 组从 1.71 减少到 1.49，G3 组从 1.72 减少到 1.62）。与 G1 组（从 1.21 减少到 1.17）相比，G3 组从干预前到干预后的蔬菜摄入量观察到的变化（从 1.13 增加到 1.21）差异有统计学意义。
精心设计的基于网络的社会营销干预措施辅以印刷信件可以帮助改善儿童对水、水果、软饮料和甜食的摄入。除了网络沟通外，使用短信来支持更大的行为改变只会导致蔬菜的微小显著积极变化，而除了网络外使用电子邮件并没有导致任何显著差异。
该试验在 ISRCTN 注册处（ID ISRCTN48730279）进行了回顾性注册。
