Factors associated with fruit and vegetable consumption among people in the highest risk area for Cholangiocarcinoma in Thailand

Background: Over the past 30 years, the incidence of cholangiocarcinoma (CCA) in the Northeast of Thailand has been high and has tended to increase. Fruits and vegetables (FV) were accepted as protective factors against CCA. The prevalence of FV consumption among Northeast people is lower than recommended, which is a significant health problem that must be urgently solved. Objectives: This study investigated the factors associated with FV consumption among people in Ubon Ratchathani, one of the high-risk areas of Thailand. Methods: A multi-stage sampling method was used to select the population aged 40 years and over. Data were analyzed using descriptive and inferential statistics. A logistic regression analysis was performed to identify the factors associated with FV consumption. Results: Out of the total 744 respondents, only 11.83% consumed FV according to the standard of <400 grams/day. The bio-social factor regarding an average family income of more than 15,000 Baht had a 10.54 times greater effect on FV consumption (AOR=10.54, 95% CI: 7.59-20.57). Purchasing FVs from mobile sales trucks (AOR=4.11, 95% CI: 1.69-9.97) and receiving information from radio (AOR=1.97, 95% CI: 1.14-3.39) were associated with standard FV consumption. However, a good level of attitude had decreased the risk of FV consumption (AOR=0.30, 95% CI: 0.18-0.49). Conclusion: The prevalence of FV consumption among the study population is considerably low. Family income, purchasing from mobile sales trucks, receiving information from radio, and having a positive attitude were associated with standard FV consumption among people in Thailand's highest-risk area for CCA. Relevant organizations should organize activities to provide people of every economic status with knowledge and attitude on FV consumption via radio or social media and support access to quality and safe mobile sales trucks to meet consumption standards and prevent as well as reduce the risk of CCA.
