Abstract

Aims: Intensive lifestyle, dietary interventions and patient education have been recommended as key milestones in to facilitate the management of Diabetes and contain the growing incidence. We performed a systematic review and meta-analysis to assess the health benefits of medical nutrition therapy among patients with diabetes. Design: A systematic search was performed in MEDLINE/PubMed, SCOPUS, and Cochrane library from onset up to February 2019 to identify trials investigating the health effect of Medical nutrition (MNT) in patients with diabetes. Random-effects models were used to calculate the effect sizes as weighted mean difference (WMD) and 95% confidence intervals (CI). Results: Eleven studies containing 1227 participants were included in the meta-analysis. Pooled results showed a significant reduction in Fasting blood sugar (FBS) (WMD= −8.85 mg/dl, 95% CI: −14.41, −3.28), HbA1c (WMD: −0.43%, 95% CI: −0.69, −0.17), weight (WMD: −1.54 kg, 95% CI: −2.44, −0.64), Body mass index (BMI) (WMD: −0.34 Kg/m2, 95% CI: −0.52, −0.17), waist circumference (WMD: −2.16 cm, 95% CI: −4.09, −0.23), cholesterol (WMD: −4.06 mg/dl, 95% CI: −7.31, −0.81), Systolic blood pressure (SBP) (WMD: −7.90 mmHg, 95% CI: −13.03, −2.77). Results of meta-regression analysis based on age of participants and duration of intervention were not significant. Conclusions: Patients with diabetes who received medical nutrition therapy showed significant improvements in outcome measures of FBS, HbA1c, weight, BMI, waist circumference, cholesterol, and SBP.
