Colorectal Cancer (CRC) Screening Literacy and Facilitators Related to a Free Screening Program in Thailand.

OBJECTIVE: This study aimed to evaluate CRC screening literacy and to determine the association between demographic characteristics and levels of CRC screening literacy and facilitators motivating participation. METHODS: This cross-sectional study was carried out with 1,272 Thai citizens aged 50-70 years consenting to complete the screening protocol. Data were collected at the final visit by a self-reported questionnaire which was developed and validated using I-CVI=1. Difficulty of CRC screening knowledge dimension was tested by KR20, Cronbach's alpha 0.49. RESULTS: The majority of participants, 834 (65.6%) had sufficient CRC screening literacy and association between characteristics and levels of CRC screening literacy was not different. Comparing between characteristics and facilitators showed significant differences in trusting healthcare providers, perceiving harmless procedures, having constipation and time available. By married and own income participants exhibited lower trust in healthcare providers, 68% (OR 0.32, 95%CI 0.14 - 0.73) and 59% (OR 0.41, 95%CI 0.19 - 0.95), respectively. Married individuals perceived the procedures of screening involved higher harm, 32% (OR 0.68, 95%CI 0.45 - 0.99). Female and age over 60 with constipation constituted higher screening, 1.9 fold (OR 1.93, 95%CI 1.44 - 2.60) and 1.4 fold (OR 1.44, 95%CI 1.09 - 1.90). Though time available, age over 60 was lower screening 56% (OR 0.44, 95%CI 0.24 - 0.80), while own income and income more than 30,000 THB/month participants constituted higher screening 15 fold (OR 15.14, 95%CI 4.72 - 48.56) and 2.5 fold (OR 2.50, 95%CI 1.50 - 4.18), respectively. CONCLUSION: CRC screening literacy of participants was high. The association between characteristics and CRC screening literacy levels did not differ while characteristics and facilitators differed in some aspects. The free program promoted CRC screening equity; however, multilevel facilitators must be concerned, prioritized and intervened to motivate participation.

Association between Low Fruit and Vegetable Consumption and Colorectal Polyps in Thailand.

OBJECTIVE: This study aimed to evaluate the association between low fruit and vegetable consumption and colorectal polyps. METHODS: A retrospective study was conducted among 1,228 participants aged 50-65 years who completed 2-time colonoscopy exams at the first and the fifth year of a colorectal screening program. Consuming less than one serving of fruit and vegetable daily was rated as low. Colorectal polyps from colonoscopy findings were recognized in 3 types: hyperplastic, low risk and high risk adenomatous polyps. RESULTS: The findings demonstrated high prevalence of low fruit (93.6%) and low vegetable (85.8%) consumption. Exercising individuals were more likely to consume both fruit (OR 2.28, 95%CI 1.42-3.65) and vegetable (OR 1.40, 95%CI 1.00-1.96), while smoking history individuals tended to consume vegetable (OR 2.08, 95%CI 1.22-3.55). Low fruit consumption was strongly associated with high risk adenomatous polyps (OR 4.39, 95%CI 2.40-8.03), while low vegetable consumption was distinctively associated with low risk (OR 6.26, 95%CI 4.11-9.55) and high risk adenomatous polyps (OR 8.64, 95%CI 5.30-14.09). CONCLUSION: This study provides additional evidence of the association between low fruit and vegetable consumption and colorectal polyps. Enhancing people fiber eating behavior may help preventing colorectal cancer risk.
