Abstract
As the incidence and prevalence of diabetes increases, intervention through dietary education is becoming more important for diabetes control. This systematic review aimed to confirm the ef-fect of dietary intervention education on diabetes control. The study subjects were type 2 diabet-ic patients, and the main outcome variable was glycosylated hemoglobin level (HbA1c). The target studies were randomized controlled trials. Thirty-six studies were included in the analysis, of which 33 were included in the meta-analysis. The effect size between the dietary education and general intervention, was -0.42 (n=5,639, MD=-0.42; 95% CI -0.53 to -0.31) and was signifi-cantly different (Z=7.73, P<.001). When subgroup analyses were performed following the appli-cation periods, intervention methods, and intervention contents, the mean differences in 4–6-month application, individual education, diet-exercise-psychosocial intervention were -0.51, (n=2,742, 95% CI -0.71 to -0.32), -0.63 (n=627, 95% CI -1.00 to -0.26), and -0.51 (n=3.244, 95% CI -0.71 to -0.32), respectively. Dietary education interventions provided for at least 3 months were highly effective in controlling blood sugar levels. Regarding the education method, individual-ized education was more effective, and for this, contact or non-contact education may be applied. Combining diet, exercise, and psychosocial intervention is more effective than diet education alone.
