Abstract

Objective 目的

To test the effectiveness of a brief behavioural intervention to prevent weight gain over the Christmas holiday period.

验证简单行为干预预防圣诞节假期期间体重增加的效果

Design 设计

Two group, double blinded randomised controlled trial.

两组双盲随机临床试验

Setting 场景

Recruitment from workplaces, social media platforms, and schools pre-Christmas 2016 and 2017 in Birmingham, UK.

英国伯明翰2016年与2017年圣诞节前从工作单位、社交媒体平台以及学校招募受试者

Participants 研究人群

272 adults aged 18 years or more with a body mass index of 20 or more: 136 were randomised to a brief behavioural intervention and 136 to a leaflet on healthy living (comparator). Baseline assessments were conducted in November and December with follow-up assessments in January and February (4-8 weeks after baseline).

272名年龄18岁以上BMI超过20的成年人:136名随机分至简的行为干预组,136名分至对照组(有关健康生活习惯的宣传页)。在11月和12日进行基线评估,1月和2月(基线后4-8周)进行随访评估。

Interventions 干预措施

The intervention aimed to increase restraint of eating and drinking through regular self weighing and recording of weight and reflection on weight trajectory; providing information on good weight management strategies over the Christmas period; and pictorial information on the physical activity calorie equivalent (PACE) of regularly consumed festive foods and drinks. The goal was to gain no more than 0.5 kg of baseline weight. The comparator group received a leaflet on healthy living.

干预措施旨在通过常规并记录称重后绘制体重曲线限制饮食;在圣诞节期间提供有关良好体重管理策略的相关信息;以及有关常规节日饮食的体力活动热卡当量(PACE)的图像信息。目标为与基线体重相比,体重增加不超过0.5 kg。对照组收到有关健康生活习惯的宣传页。

Main outcome measures 主要预后指标

The primary outcome was weight at follow-up. The primary analysis compared weight at follow-up between the intervention and comparator arms, adjusting for baseline weight and the stratification variable of attendance at a commercial weight loss programme. Secondary outcomes (recorded at follow-up) were: weight gain of 0.5 kg or less, self reported frequency of self weighing (at least twice weekly versus less than twice weekly), percentage body fat, and cognitive restraint of eating, emotional eating, and uncontrolled eating.

主要预后指标为随访时体重。主要分析比较了干预组及对照组随访时的体重,并针对基线体重及参加减肥课程等变量进行校正。次要预后指标(随访时记录)包括体重增加不足0.5 kg,自己报告称重频率(至少每周2次 vs. 每周不到2次)、体脂含量,以及进食节制、情绪化进食和非控制进食。

Results 结果

Mean weight change was −0.13 kg (95% confidence interval −0.4 to 0.15) in the intervention group and 0.37 kg (0.12 to 0.62) in the comparator group. The adjusted mean difference in weight (intervention−comparator) was −0.49 kg (95% confidence interval −0.85 to −0.13, P=0.008). The odds ratio for gaining no more than 0.5 kg was non-significant (1.22, 95% confidence interval 0.74 to 2.00, P=0.44).

干预组平均体重变化为-0.13 kg(95% 可信区间 −0.4 to 0.15),对照组为0.37 kg (0.12 to 0.62)。校正后体重改变平均差异为(干预组-对照组)−0.49 kg (95% 可信区间 −0.85 to −0.13, P=0.008)。体重增加不超过0.5 kg的比数比无显著差异 (1.22, 95% 可信区间 0.74 to 2.00, P=0.44)。

Conclusion 结论

A brief behavioural intervention involving regular self weighing, weight management advice, and information about the amount of physical activity required to expend the calories in festive foods and drinks prevented weight gain over the Christmas holiday period.

包括常规称重、体重管理建议以及消耗节日饮食所需活动量在内的简单行为干预能够预防圣诞节期间的体重增加。
