Abstract: Background　Rheumatoid arthritis （RA） prevalence is increasing，and its diagnosis and treatment are becoming standardized gradually.Pain is the chief complaint.Whether subjective pain is associated with food intake is a generally concerned problem in these patients due to influence of some traditional ideas，and it has been studied rarely in recent studies，leading to insufficient adequate information for conducting effective patient education.Therefore，it is necessary to carry out relevant research.Objective　To investigate the effect of food intake on subjective pain in RA patients，providing evidence for health education for these patients.Methods　The outpatients and inpatients with RA from the First Affiliated Hospital of Guangxi Medical University，and Fourth Affiliated Hospital of Guangxi Medical University were enrolled during December 2014 to October 2016，and were surveyed using a questionnaire covering demographic data，and the influence of food intake on subjective pain（changes in pain level after eating different foods）.Results　A total of 500 cases participated in the survey.Among them，206（41.2%）thought that food intake had effect on subjective pain，but others 〔294（58.8%）〕 did not think so.However，these two groups showed similar severity distribution of disease activity （χ2=2.432，P=0.296）.The top three foods that aggravated subjective pain were poultry 〔45.9%（89/194）〕，red meat 〔30.9%（60/194）〕 and bamboo shoots 〔24.7%（48/194）〕.The top three foods that alleviated subjective pain were Chinese red dates 〔50.0%（21/42）〕，longan 〔28.6%（12/42）〕 and ginger 〔19.0%（8/42）〕.The prevalence of opinions about food intake aggravating subjective pain level was higher in females than that of males （P<0.05）.RA residents in coastal areas were more likely to believe that food intake could alleviate subjective pain compared with those from hilly areas （P<0.05）.Conclusion　The subjective pain level of some RA patients is influenced by food intake.Eating poultry，red meat and bamboo shoots are thought to be aggravating factors for pain level，whereas eating Chinese red dates，longan and ginger are considered to be alleviating factors of the pain.Females are more likely to think that food intake aggravates subjective pain.And those living in coastal areas are more likely to believe that food intake can reduce subjective pain compared with those living in hilly areas.
