Evangelidis N, et al. - In this systematic review of trials of lifestyle behavior change interventions (comprising diet, physical activity, smoking and/or alcohol) published to September 2018 in adults with CKD stages 1–5, experts determined and assessed behavior change techniques and functions in lifestyle interventions in order to prevent the progression of CKD. In total, 26 studies involving 4,263 persons were involved. In most studies, the risk of bias was high or unclear. Interventions included diet, physical activity or general lifestyle. The most commonly used function was education, followed by enablement, training, persuasion, environmental restructuring, modeling, and incentivization. Behavioral instruction, social support, behavioral demonstration, feedback on behavior and behavioral practice/rehearsal were the most prevalent behavior change techniques. Eighteen studies exhibited a notable betterment in at least one primary outcome, all of which involved education, persuasion, modeling, and incentivization. In conclusion, for CKD individuals, lifestyle behavior change interventions commonly used education, goal setting, feedback, monitoring, and social support. Moreover, the most promising interventions involved education and practiced diverse intervention functions (persuasion, modeling, and incentivization).
