Bottom Line: Five RCTs with a total of 1932 participants met the inclusion criteria.This review was not however able to clearly characterise effective interventions promoting increased physical activity in this patient group.Further research is required to establish effective interventions to promote adherence to physical activity in this population.

ABSTRACT

Background: Little is known about colorectal adenoma patients' ability to adhere to behavioural interventions promoting a change in diet and physical activity. This review aimed to examine health behaviour intervention programmes promoting change in diet and/or physical activity in adenoma patients and characterise interventions to which this patient group are most likely to adhere.

Methods: Searches of eight databases were restricted to English language publications 2000-2014. Reference lists of relevant articles were also reviewed. All randomised controlled trials (RCTs) of diet and physical activity interventions in colorectal adenoma patients were included. Eligibility and quality were assessed and data were extracted by two reviewers. Data extraction comprised type, intensity, provider, mode and location of delivery of the intervention and data to enable calculation of four adherence outcomes. Data were subject to narrative analysis.

Results: Five RCTs with a total of 1932 participants met the inclusion criteria. Adherence to the goals of the intervention ranged from 18 to 86 % for diet and 13 to 47 % for physical activity. Diet interventions achieving ≥ 50 % adherence to the goals of the intervention were clinic based, grounded in cognitive theory, delivered one to one and encouraged social support.

Conclusions: The findings of this review indicate that behavioural interventions can encourage colorectal adenoma patients to improve their diet. This review was not however able to clearly characterise effective interventions promoting increased physical activity in this patient group. Further research is required to establish effective interventions to promote adherence to physical activity in this population.

Mentions: Figure 1 shows the outcome of the search process and application of the selection criteria. The electronic searches identified 2221 potentially relevant articles. Following removal of 805 duplicates, 1416 papers remained. A further 1206 of these articles were excluded following review of the title or abstract and 196 articles were excluded after a full review of the article. The reasons for exclusion are provided in Table 2. The 14 remaining articles reported on nine RCTs which included individuals with a diagnosis of colorectal adenoma. Two of these RCTs were excluded from further review because they reported on RCTs of a dietary supplement and two RCTs were excluded because calculation of adherence was not possible. Five RCTs of a diet and/or physical activity intervention in colorectal adenoma patients were included in the current review [31–35].Fig. 1
