The screening context may provide a "teachable moment" for promoting health behaviours. The present study examined the impact on diet, alcohol and physical activity of providing individually-tailored advice in the context of flexible sigmoidoscopy (FS) screening.
Adults (n=365) aged 58-59 years who attended FS screening between 2006 and 2008 and had no abnormalities detected were randomised to one of three groups: (i) control (usual care); (ii) standard leaflet on healthy lifestyle; or (iii) standard leaflet plus brief, tailored feedback based on information from the pre-screening questionnaire. A 6-month follow-up questionnaire assessed group differences in fruit and vegetable consumption, alcohol intake and physical activity.
More people in the tailored group were meeting the 5-a-day fruit and vegetable recommendation at 6 months (OR: 2.28, CI[1.09, 4.76]). For physical activity there was a non-significant trend towards meeting current activity guidelines in the tailored group (OR: 1.26, CI[0.62, 2.55]). Alcohol intake was low overall and did not change in any group.
Tailored advice given in the context of cancer screening may provide an opportunity to improve dietary behaviours. Further research is needed to determine whether screening provides a unique "teachable moment" or if similar effects can be achieved in other health settings.
筛查背景可为促进健康行为提供“教学时刻”。本研究探讨了在灵活乙状结肠镜检查（FS）筛查背景下提供个性化建议对饮食、酒精和体力活动的影响。
2006 年至 2008 年间接受 FS 筛查且未发现异常的 58-59 岁成年人被随机分为三组：（i）对照组（常规护理）；（ii）健康生活方式标准手册；或（iii）标准手册加基于预筛查问卷信息的简短个性化反馈。6 个月随访问卷评估了组间在水果和蔬菜摄入、饮酒和体力活动方面的差异。
在 6 个月时，更多的个性化组人群符合每日 5 份蔬果推荐量（OR：2.28，CI[1.09，4.76]）。对于体力活动，个性化组有达到当前活动指南的非显著趋势（OR：1.26，CI[0.62，2.55]）。总体而言，饮酒量较低，且任何一组均未发生变化。
在癌症筛查背景下提供的个性化建议可能为改善饮食行为提供机会。需要进一步研究确定筛查是否提供独特的“教学时刻”，或者是否可以在其他健康环境中获得类似效果。
