Abstract Background 

Screening programmes provide an opportunity to combine early detection programmes with prevention strategies for chronic disease risk reduction. The aim of the current exploratory research was to identify diet and activity habits in adults diagnosed with colorectal adenomas on screening colonoscopy in order to inform the development of an intervention study in this patient group. Methods 

Participants were recruited from colonoscopy clinics and completed a 7-day food diary and physical activity record. Results 

Valid food diaries were completed by 32 participants. Mean daily intake of nonstarch polysaccharide was estimated at 14.2  (SD 4.2) g per day and fruit and vegetable intake (FVI) at 3.6 (SD 1.9) portions. The highest quartile of FVI consumers reported greater consumption of fruit (on any occasion) and vegetables (at evening meal) compared with low FVI consumers. Physical activity records (n = 36) indicated that walking was the most common method of activity with few indications of leisure time sport. Overall, 37% of participants failed to meet minimum recommend activity levels. Conclusion 

The magnitudes of change in activity and diet required to conform with current guidelines were estimated. Food habits that were pertinent to the population were identified and help to provide goal-based guidance for intervention design.
