These analyses used 79,468 participants initially free of cancer. Baseline dietary data were obtained using a food frequency questionnaire and incident cancers by matching with state and Canadian provincial cancer registries. Hazard ratios (HRs) were estimated using proportional hazard regression. Small amounts of missing data were filled using multiple imputations.\u003Cbr>Results: Overall cancers, all vegetarians combined compared with nonvegetarians, had HR: 0.88; 95% confidence interval (CI): 0.83,0.93; P \u003C 0.001, and for medium frequency cancers, HR: 0.82; 95% CI: 0.76, 0.89; P \u003C 0.001. Of specific cancers, colorectal (HR: 0.79; 95% CI: 0.66, 0.95; P ¼ 0.011), stomach (HR: 0.55; 95% CI: 0.32, 0.93; P ¼ 0.025), and lymphoproliferative (HR: 0.75; 95% CI: 0.60,0.93; P ¼ 0.010) cancers, were significantly less frequent among vegetarians. A joint test that HR ¼ 1.0 for all vegetarian subtypes compared with nonvegetarians was rejected for cancers ofthe breast (P ¼ 0.012), lymphoma (P ¼ 0.031), all lymphoproliferative cancers (P ¼ 0.004), prostate cancer (P ¼ 0.030), colorectal cancers (P ¼ 0.023), medium frequency cancers (P \u003C 0.001), and for all cancers combined (P \u003C 0.001) .\u003Cbr>Conclusions: These data indicate a lower risk in vegetarians for all cancers combined, as well as for medium-frequency cancers as a group. Specific cancers with evidence of lower risk are breast, colorectal, prostate, stomach, and lymphoproliferative subtypes. Risk at some other sites may also differ in vegetarians, but statistical power was limited.\u003Cbr>Keywords: vegetarian subtypes, site-specific cancers, Seventh-day Adventists, North American subjects, Adventist Health Study-2 |\n\nIntroduction  \nA common characteristic of vegetarians, as compared with more typical Western diets, is a greater content of fruit, vegetables, nuts, and legumes [1,2], which contain phytochemicals thought to protect against cancer [3] . In addition, there is the absence of meats, some of which probably promote certain cancers. Vegetarians are, on average (mean  \nvalues), less prone to overweight [4,5], wh","cbCaibj5kCMKDlPt","https://ap.wps.com/l/cbCaibj5kCMKDlPt","pdf",1164178,"English","# Abstract\n# Introduction","[{\"question\":\"What was the main objective of this study?\",\"answer\":\"To describe multivariable-adjusted associations between different types of vegetarian diets (vs nonvegetarians) and cancer risk at different bodily sites.\"},{\"question\":\"How were participants and cancer outcomes determined?\",\"answer\":\"The cohort included North American Seventh-day Adventists with 79,468 participants initially free of cancer; baseline diet came from a food frequency questionnaire, and incident cancers were identified by matching with state and Canadian provincial cancer registries.\"},{\"question\":\"Which cancer outcomes showed significantly lower risk among vegetarians?\",\"answer\":\"Vegetarians had significantly less frequent overall cancers and medium-frequency cancers, and specific reductions were reported for colorectal, stomach, and lymphoproliferative cancers.\"}]","Longitudinal associations between vegetarian dietary habits and site-specific cancers in the Adventist Health Study-2 North American cohort | PDF",1790172807,23]
