Methods: We analyzed data from 7216 men and women (55–80 years) without CRC at baseline from the PREvención con DIeta MEDiterránea study. Baseline consumption of vitamin D was assessed using a validated 137-item food frequency questionnaire. Cox proportional hazards ratios (HRs) of CRC and colon cancer incidence were estimated for quartiles and per 1-SD of baseline vitamin D intake. Results: During a median follow-up of 6 years, we documented 97 incident CRC cases after the exclusion of subjects with no baseline dietary data and/or outliers of energy intake. A non-significant HRs and 95% confidence intervals (CIs) of CRC for the comparison of extreme quartiles (4th vs 1st) of vitamin D intake were observed [0.55 (0.30–1.00), P for trend = 0.072], whereas it was significant for colon cancer incidence alone [0.44 (0.22–0.90), P for trend = 0.032]. However, this association became significant in CRC and colon cancer incidence, after excluding 391 subjects consuming baseline vitamin D and/or calcium medication or prescribed supplements [0.52 (0.28–0.96) and 0.41 (0.12–0.85), respectively]. Conclusion: A higher dietary intake of vitamin D was significantly associated with a reduced CRC risk in individuals at high cardiovascular risk.||URI:||http://hdl.handle.net/10553/107456||ISSN:||1436-6207||DOI:||10.1007/s00394-021-02585-1||Source:||European Journal of Nutrition[ISSN 1436-6207], (Mayo 2021)|
