Association between Dietary Inflammatory Index and Risk of Colorectal Adenomatous Polyps in Kashgar Prefecture of Xinjiang, China.

Malignant colorectal tumors and precancerous lesions are closely associated with chronic inflammation. Specific dietary patterns can increase chronic inflammation in the body, thereby promoting the occurrence of tumors and precancerous lesions. We have conducted a case-control study in Kashgar Prefecture, Xinjiang, China, to explore the association between the energy-adjusted dietary inflammatory index (E-DII) and the risk of colorectal adenomatous polyps (CAP). A total of 52 newly diagnosed patients with CAP and 192 controls at the First People's Hospital of Kashgar Prefecture were enrolled in this study. Dietary information was collected using a food frequency questionnaire. The E-DII was calculated based on dietary data, reflecting an individual's dietary inflammatory potential. Logistic regression models were used to evaluate the relationship between the E-DII and the risk of CAP, with adjustments for potential confounding factors. The results showed that the maximum anti- and pro-inflammatory values of E-DII were -4.33 and +3.48, respectively. Higher E-DII scores were associated with an increased risk of CAP, and this association remained statistically significant after adjusting for age, sex, body mass index, smoking status, and other relevant variables. Notably, a more pro-inflammatory dietary pattern may be related to an increased risk of developing CAP in Kashgar Prefecture.

Associated Behavioral Factors and Prevalence of the Common Anorectal Disease Among Uyghur Male Adults of China: A Population-Based Crosssectional Study.

Objectives: We investigated the behavioral associated factors and prevalence of common anorectal disease (hemorrhoids, perianal pruritus, anal fistula, and others) among Uyghur male adults in southern Xinjiang. Methods: We conducted a cross-sectional study with a random sampling method from December 2020 to March 2021. Uyghur males aged 18 years and older were selected from Kashgar Prefecture in Xinjiang. The prevalence was evaluated by a bilingual questionnaire (including socio- demographic information, dietary habit, lifestyle, and behavioral habits) and anorectal examinations. The chi-square test was used for categorical variables. Logistic regression analysis was used to identify potential associated factors.Results: A total of 402 Uygur males aged ≥ 18 years were included in the final analysis. Of those, 192 (47.8%) participants were identified with common anorectal disease (CAD). Older age, lower education attainment, being a farmer, having lower personal annual income, having a high level of alcohol consumption, performing less anus-rinsing after defecation, and having less pubic hair removal were significantly associated with CAD. Conclusions: Common anorectal disease is a significant public health concern for the Uygur male population. Anus-rinsing after defecation and pubic hair removal are ethnic-specific behaviors among Uygur and could be preventive strategies for CAD.
