Diabetes mellitus (DM) is a progressive disease that may develop to serious difficulties varying from microvascular to macrovascular complications. Quality of life of patients with DM dramatically declines after the time of diagnosis.
Two groups of DM patients were recruited to assess their quality of life. The interventional group (IG), included 15 patients, was assigned on whole-grain food and plant based diet for 12 weeks with no any medication for DM. Control matching group (CG), of 15 patients, was assigned to conventional diet and medications for DM. At the end of follow up period both groups filled WHO qol-bref questionnaire which contained 4 domains related to their quality of life.
Interventional group showed significant differences in all domains as follows: Physical domain was 57.87± 12.9 and 65.67 ± 5.2 for CG and IG respectively. Psychological domain was 46.0 ± 17.5 and 64.7 ± 6.6 for CG and IG respectively. Social domain 41.7 ± 18.18 and 72.5 ±14.3 for CG and IG respectively. Environmental domain 52.5 ± 12.3 and 60.6 ± 7.4 for CG and IG respectively. Overall quality of life scored 48.2 and 66.0 for CG and IG respectively.
Patients of interventional group have shown improvement in their quality of life due to adopting plant based diet. Moreover, such a group had no medication during the follow up period. However, large scale study is recommended to verify this pilot study’s results.
Key words: diabetes, quality of life, WHO qol-bref, plant-based diet.
