关于如何改善和创造癌症幸存者的可持续生活方式行为知之甚少。基于社会认知理论（SCT）的干预措施已经显示出希望。本综述研究了针对癌症幸存者的基于SCT的体力活动和营养干预措施的效果，并确定了与其疗效相关的因素。对7个数据库的系统性检索确定了随机对照试验，这些试验（i）针对成年癌症幸存者（从诊断开始的任何时间点）;（ii）报告了体力活动、饮食或体重管理的主要结局;（iii）包括针对体力活动或饮食的基于SCT的干预。进行了定性综合和荟萃分析。理论结构和干预的特点进行了检查，以确定与干预效果的因素。18项研究（在33篇出版物中报告）符合审查纳入标准。Meta分析（n = 12）显示，对体力活动有显著的干预效果（标准化平均差异（SMD）= 0.33; P < 0.01）。大多数针对饮食变化的研究（八分之六）报告了饮食质量至少在一个方面的显着改善。没有SCT结构与干预效果相关。没有一致的趋势，有关干预提供方法或干预是否针对单一或多种行为。基于SCT的干预措施显示出改善癌症幸存者身体活动和饮食行为的希望，使用一系列干预提供模式。需要进一步的工作来了解这些干预措施如何以及为什么能够改善行为。针对饮食或体力活动的基于SCT的干预措施是安全的，并会导致饮食和体力活动行为发生有意义的变化，从而改善健康状况。
Little is known about how to improve and create sustainable lifestyle behaviors of cancer survivors. Interventions based on social cognitive theory (SCT) have shown promise. This review examined the effect of SCT-based physical activity and nutrition interventions that target cancer survivors and identified factors associated with their efficacy. A systematic search of seven databases identified randomized controlled trials that (i) targeted adult cancer survivors (any point from diagnosis); (ii) reported a primary outcome of physical activity, diet, or weight management; and (iii) included an SCT-based intervention targeting physical activity or diet. Qualitative synthesis and meta-analysis were conducted. Theoretical constructs and intervention characteristics were examined to identify factors associated with intervention efficacy. Eighteen studies (reported in 33 publications) met review inclusion criteria. Meta-analysis (n = 12) revealed a significant intervention effect for physical activity (standardized mean difference (SMD) = 0.33; P < 0.01). Most studies (six out of eight) that targeted dietary change reported significant improvements in at least one aspect of diet quality. No SCT constructs were associated with intervention effects. There were no consistent trends relating to intervention delivery method or whether the intervention targeted single or multiple behaviors. SCT-based interventions demonstrate promise in improving physical activity and diet behavior in cancer survivors, using a range of intervention delivery modes. Further work is required to understand how and why these interventions offer promise for improving behavior. SCT-based interventions targeting diet or physical activity are safe and result in meaningful changes to diet and physical activity behavior that can result in health improvements.
