Objective To analyze the mediating effect of social support on health literacy and medication comp-liance among elderly diabetic patients in rural Guangdong.Methods A questionnaire survey was conducted among 1 495 elderly people using the Diabetes Health Literacy Scale,the Social Support Rating Scale and the Medication Adherence Scale.Results The score of diabetes health literacy in rural elderly was(80.79±9.87),social support score was(26.69±3.72),medication adherence score was(4.98±0.99),and the rate of moderate or above medica-tion adherence was only 32.1％(467/1 495).Medication adherence and social support(r=0.704,P＜0.001)and health literacy(r=0.811,P＜0.001)were significantly correlated.Social support had a mediating effect of 0.031(95％boot CI:0.140-0.292)between health literacy and medication adherence.After age stratification,only 65-＜75 years old groups found a mediating effect between social support on health literacy and medication adherence[0.059(95％CI:0.035-0.073)].Conclusion Health literacy can directly have a positive effect on medication adherence,and can have an indirect effect through social support.Rural elderly diabetic groups should enhance their health lite-racy level and make full use of social support to improve medication compliance.
