摘要

背景:这项研究旨在了解一种行为的变化如何影响其他行为,称为“转移效应”,可以扩展复合健康风险行为之间共享结构的知识,并改进促进同时发生行为变化的方法。目前的研究探讨了完成体育活动(PA)随机对照试验的参与者是否在不干预饮食或营养的情况下改善了饮食。方法:美国成年人(N = 283)被随机分配到12周的运动视频游戏、标准运动或注意力控制中。进行二次分析,以检查干预结束时(EOT)和6个月随访时干预对饮食的可能转移影响。对潜在的PA结构(即运动乐趣、自我效能)和人口统计学(如年龄、性别)进行了评估。PA,特别是中等至剧烈的体力活动水平(MVPA),使用自我报告测量。饮食是使用“给你的盘子打分”饮食评估来衡量的。结果:研究结果支持随机化效应与MVPA增加的可能性较高相关(β = 30.00,95%CI = 4.46,64.46)和EOT时的饮食改善(β = 1.48,SE = .83,P = .01)和随访(β = 1.74,SE = .52,P = .02)。在EOT时,饮食的变化与更高的PA享受相关(β=0.41,SE=0.15,P = .01)。这种对饮食的干预效果受到性别的调节,女性的饮食改善程度高于男性(β =  - .78,SE = 13,P = .03)。6个月时,饮食改善与更高的自我效能感相关(β = .04,SE = .01,P = .01)。结论:本研究显示了两种协同行为之间存在转移效应的证据,并扩展了对预测这种行为变化发生的因素的理解。

Exploring Factors Associated with Dietary Improvement Among Participants Who Completed a Randomized Controlled Trial for Physical Activity: Evidence of a Transfer Effect.

Background: This research aimed at understanding how changes in one behavior affect other behaviors, known as "transfer effect," could extend knowledge of shared constructs among compound health risk behaviors, and improve methods for promoting simultaneous behavior changes. The current study explored whether participants who completed a randomized controlled trial for physical activity (PA) improved their diet with no intervention in diet or nutrition.

Methods: US adults (N = 283) were randomly assigned to 12 weeks of either exercise videogames, standard exercise, or an attention control. Secondary analyses were conducted to examine a possible transfer effect of the intervention on diet at end of intervention (EOT) and 6-month follow-up. Assessments of potential PA constructs (i.e., exercise enjoyment, self-efficacy) and demographics (e.g., age, gender) were conducted. PA, specifically moderate-to-vigorous levels of physical activity (MVPA), was measured using a self-report measure. Diet was measured using the Rate Your Plate dietary assessment.

Results: Findings support that a randomization effect was associated with a higher likelihood of increasing MVPA (β = 30.00, 95% CI = 4.46, 64.46) and dietary improvement at EOT (β = 1.48, SE = .83, P = .01) and follow-up (β = 1.74, SE = .52, P = .02). At EOT, changes in diet were associated with higher PA enjoyment (β = 0.41, SE = 0.15, P = .01). This intervention effect on diet was moderated by gender, with women showing more dietary improvement than men (β =  - .78, SE = 13, P = .03). At 6 months, dietary improvement was associated with greater self-efficacy (β = .04, SE = .01, P = .01).

Conclusion: This study shows evidence of a transfer effect among two synergistic behaviors and expands understanding of factors that predict the occurrence of this type of behavior change.

期刊介绍: The International Journal of Behavioral Medicine (IJBM) is the official scientific journal of the International Society for Behavioral Medicine (ISBM). IJBM seeks to present the best theoretically-driven, evidence-based work in the field of behavioral medicine from around the globe. IJBM embraces multiple theoretical perspectives, research methodologies, groups of interest, and levels of analysis. The journal is interested in research across the broad spectrum of behavioral medicine, including health-behavior relationships, the prevention of illness and the promotion of health, the effects of illness on the self and others, the effectiveness of novel interventions, identification of biobehavioral mechanisms, and the influence of social factors on health. We welcome experimental, non-experimental, quantitative, qualitative, and mixed-methods studies as well as implementation and dissemination research, integrative reviews, and meta-analyses.
