The aim of this pilot study was to evaluate the effectiveness of the U.K. Change4Life Sugar Swaps campaign for improving nutritional intake in a small sample of families prior to the 2015 nationwide launch. A total of 49 participants from 14 families received information and materials during a two-week intervention period in November 2014 encouraging them to swap high sugar foods and drinks for low sugar alternatives. Daily dietary intake was reported with online food diaries over four stages, each two weeks in length: (i) baseline (no information provided), (ii) intervention when Sugar Swaps materials were accessible, (iii) immediate follow-up, and (iv) one year on from baseline. Data were analysed for sugar, glucose, fructose, sucrose, lactose, fat, saturated fat, carbohydrate, protein, salt, fibre, vitamin C, and energy. During the intervention, significant daily reductions of 32 g sugar, 11 g fat, and 236 kcal for each family member were observed, among others, and 61% of benefits achieved during the intervention period were maintained at immediate follow-up. Encouragingly, for children, reductions in sugar, sucrose, fat, saturated fat, carbohydrate, and energy were observed one year on. The Sugar Swaps Campaign is potentially an effective public health intervention for improving short- and long-term dietary behaviour for the whole family.
本初步研究旨在评估英国“改变生活，减少糖份”活动在 2015 年全国推广前，对改善一小部分家庭营养摄入的效果。2014 年 11 月，共有 14 个家庭的 49 名参与者参与了为期两周的干预，在此期间他们获得了有关信息和材料，鼓励他们用低糖替代品替换高糖食品和饮料。参与者通过在线饮食日记记录了四个阶段（每个阶段持续两周）的日常饮食摄入情况：（i）基线（未提供信息）；（ii）干预期间可获得“糖份交换”材料；（iii）即时随访；（iv）从基线开始一年后。对糖、葡萄糖、果糖、蔗糖、乳糖、脂肪、饱和脂肪、碳水化合物、蛋白质、盐、纤维、维生素 C 和能量进行了数据分析。在干预期间，每个家庭成员的每日糖摄入量减少了 32 克，脂肪减少了 11 克，热量减少了 236 卡路里，其中部分干预效果在即时随访时仍能保持。令人鼓舞的是，在一年后，儿童的糖、蔗糖、脂肪、饱和脂肪、碳水化合物和能量摄入量均有所减少。“糖份交换”活动对于改善整个家庭的短期和长期饮食行为可能是一种有效的公共卫生干预措施。
