Mediating effect of depression between restricted diet and control status of diabetes mellitus

ObjectiveTo explore the mediating effect of depression between restricted diet and control status of diabetes mellitus.

MethodsConvenience sampling was used in this study.The self-designed general information questionnaire, self-rating depression scale(SDS), three-factor eating questionnaire(TFEQ) and control status scale for diabetics(CSSD70) were filled out by all participants.

ResultsFor all the participants, the overall score of SDS, TFEQ, and CSSD70 were(40.39±7.78), (9.58±3.06) and(43.84±9.59) points, respectively.Pearson correlation analysis showed that depression was positively correlated with restricted diet(r=0.233, P < 0.01) and negatively correlated with control status of diabetes mellitus(r=-0.237, P < 0.01).The mediating effect test showed that depression had a complete mediating effect between restricted diet and control status of diabetes mellitus, and the mediating rate was 51.81%.

ConclusionsThe depression was an intermediary variable mediating the relationship between restricted diet and control status of diabetes mellitus.
