Web-based Dietary Intervention for Diabetic Patients (myDIDeA)

24. december 2017 opdateret af: Amutha Ramadas, Monash University

Dietary Intervention Among Patients With Type 2 Diabetes Mellitus: An e-Approach

The Internet holds promise for a wide-scale promotion of dietary and lifestyle behavioural change. Website-delivered interventions have a potentially broad population reach as it is available 24 hours, and could be hosted by both government and non-governmental agencies. To date, there is no published study focused on dietary behaviour change in adults with Type 2 Diabetes Mellitus (T2DM) via a website-based system.

myDIDeA was a 12-months two-armed randomised controlled trial conducted in three tertiary public hospitals in Klang Valley, Malaysia. The primary outcome was the Dietary Knowledge, Attitude and Behaviour (DKAB) score, while the secondary outcomes included the food intake, anthropometry measurements, blood pressure and resting heart rate, blood biomarkers and the Dietary Stages of Change (DSOC) score.

Detaljeret beskrivelse

The study was designed according to the recommendations of the CONSORT statement for randomised trials of non-pharmacologic treatment. The study commenced in November 2009 after obtaining the ethical approvals from relevant authorities, and the trial has been registered with Clinicaltrials.gov (NCT01246687). After being screened for eligibility, 128 patients with Type 2 Diabetes Mellitus (T2DM) from the outpatient clinics at these hospitals were recruited into the study with informed consent. After the baseline data collection, the participants were randomised into the e-intervention (n=66) or the control (n=62) group. The e-intervention group received an intensive six-month dietary intervention through the study website, which was developed based on various established guidelines and recommendations but personalised according to the participants' DSOC, in addition to the usual standard treatment at the outpatient clinics. In contrast, the control group received the usual standard treatment given to patients with T2DM, and did not receive the website login information, or any reinforcement via e-mail or SMS. Data were collected at baseline, six months post-intervention and at 12 months follow-up. A structured and pre-tested questionnaire was used for this purpose. The anthropometry measurements, blood pressure and resting heart rate were measured at data collection. Details on the blood biomarkers were obtained from the hospital medical records. The statistical analysis revealed that myDIDeA was successful in improving overall DKAB score by improving the diabetes-related dietary knowledge and attitude of the participants. Besides, the intervention programme also have successfully improved the DSOC score of the intervention group, suggesting the participants were indeed making small but significant progress in changing their dietary behaviour. Improvement in the diet quality (improvement in vegetable intake and reduction in carbohydrate and protein intake), glycaemic control and total cholesterol have added credibility to this web-delivered intervention. The process evaluation of the study website revealed that on the average each participant logged in the website once a week and spent 11 minutes at the website per visit. The usability (facilitating conditions) scored the highest, while the acceptability (anxiety) scored the lowest.
