Abstract Objective The unknown aetiology of Serrated Polyposis Syndrome (SPS) impedes risk prediction and prevention. We investigated risk factors for SPS, overall and stratified by World Health Organization (WHO)2010 clinical criteria and by colorectal cancer (CRC). Method A retrospective case-control study involving a cross-sectional analysis from 350 unrelated individuals with SPS from the Genetics of Colonic Polyposis Study and 714 controls from the Australasian Colorectal Cancer Family Registry. Univariate and multivariate logistic regression modelling was used to determine the association between risk factors and SPS and risk factors associated with CRC in SPS. Results Female biological sex (odds ratio (OR) = 4.54; 95%Confidence interval (CI) = 2.77–7.45), increasing body mass index (BMI) at age 20 years (OR = 1.09; 95%CI = 1.04–1.13), hormone replacement therapy (OR = 0.44; 95%CI = 0.20.98), and increasing weekly folate intake (OR = 0.82; 95%CI = 0.75–0.90) were associated with SPS by multivariate analysis. Increasing weekly calcium intake (OR = 0.79; 95%CI = 0.64–0.97) and smoking > 10 cigarettes daily (OR = 0.45; 95%CI = 0.23–0.86) were associated with WHO criterion I only. The consumption of 1-100 g of alcohol per week (OR = 0.39; 95%CI = 0.18–0.83) was associated with WHO criterion III only. Smoking 1–5 cigarettes daily (OR = 2.35; 95%CI = 1.09–5.05), weekly non-steroidal anti-inflammatory drug (NSAIDs) intake (OR = 0.88; 95%CI = 0.78–0.99), and increased height (OR = 1.09; 95% = 1.05–1.13), were associated with SPS fulfilling both WHO criteria I and III. Moreover, weekly NSAIDs intake (OR = 0.81; 95%CI = 0.67–0.98) was associated with a reduced likelihood of CRC in SPS. Conclusion We identified novel risk and potential protective factors associated with SPS, some specific for certain WHO2010 criteria. Weekly use of NSAIDs may reduce the risk of CRC in people with SPS.
