Effects of Movement Control Order (MCO) During Covid-19 Pandemic on Patients With Diabetes Mellitus (DM) in Malaysian Tertiary Centers

Introduction: The Malaysian government implemented MCO or lockdown for nearly 3 months from 18 Mar to 9 Jun 2020 in response to the Covid-19 pandemic. This restricted access to usual food, workplace, and leisure sports, and also led to reduced clinic attendance. The effects of MCO on patients with chronic lifestyle diseases like DM is unknown. Methodology: This is a cross-sectional study exploring effects of MCO on adult (>18 years) DM patients (both Type 1 and Type 2) attending endocrinologist-run DM clinics in 3 tertiary centres in Malaysia. Glycaemic and metabolic parameters were collected through medical record review while data on healthcare utilisation, dietary and lifestyle habits before MCO (17 Nov 2019 to 17 Mar 2020) and during MCO were collected by investigator-administered questionnaires during routine clinic follow-up after the MCO period (10 Jun to 30 Oct 2020). Results: From a total of 207 patients (56.5% female, 73.4% T2D and 80% on insulin) no significant difference between mean (SD) A1c [8.6(2.39) % vs 8.4(2.14) %; p=0.073] or BMI [29.2(7.57) vs 29.4(9.23)kg/m2; p=0.968] were seen before and during MCO respectively. More than 95% of the patients attended clinic before MCO and at least 20.3% saw either the DM nurse educator, DM pharmacist or dietitian. In contrast, during MCO only 31.4% of patients attended clinic and less than 10% had face-to-face consultation with the DM support team. More patients also reported missing insulin (11.6% vs 7.7%) and not checking blood glucose (17.9% vs 15.5%) during MCO. Before MCO, 61.8% of patients had home-cooked food daily. During MCO this increased to 83.1%. However, there was a trend towards unhealthy eating during MCO. Patients reported eating more frequently with those eating more than 4 meals a day nearly tripled during MCO (18.4% vs 6.8%). In addition, 22% of patients recalled consuming more confectionary; a similar percentage also reported higher consumption of processed food like dry snacks, canned food and instant noodles during MCO.
