Adherence to the WCRF/AICR 2018 recommendations for cancer prevention and risk of cancer : prospective cohort studies of men and women

• BackgroundIn 2018, the World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) issued revised recommendations for cancer prevention. We examined the relation between adherence to these recommendations and risk of total cancer in two population-based Swedish prospective cohorts (29,451 men and 25,349 women).MethodsStandardized-WCRF/AICR 2018 and simplified-WCRF/AICR 2018 adherence scores were constructed based on the WCRF/AICR recommendations for body weight, physical activity, diet, alcohol consumption and dietary supplement use. Data were collected using a self-administered questionnaire.ResultsDuring the 15.4 years of follow-up, 12,693 incident cancers were ascertained. The multivariable HR between extreme categories of the Standardized-WCRF/AICR 2018 score (4.1–7 vs. 0–2) was 0.88 (95% CI = 0.82–0.95) and for the Simplified score (5–8 vs. 0–2) was 0.85 (95% CI = 0.80–0.90); each 1-score increment in recommendation adherence was associated with 3% (95% CI = 1–5%) and 4% (95% CI = 2–5%) decreased risk, respectively. Based on the Simplified scoring, most participants (>90%) did not meet WCRF/AICR 2018 recommendations regarding consumption of plant foods, limited consumption of red/processed meat and ‘fast food’/processed food, and <50% of participants met the weight and physical activity recommendations.ConclusionsAdherence to the 2018WCRF/AICR recommendations substantially reduced the risk of total cancer. Given that many people do not meet the recommendations, there is a great potential for cancer prevention.
