The effect of COVID-19 lockdown on glycemic control in patients with type 2 diabetes mellitus in Turkey

BACKGROUND AND AIMS

A national lockdown to prevent the spread of coronavirus disease (COVID-19) in Turkey was introduced in March 2020. We think that lockdowns may lead to weight gain and worsening of glycemic parameters in patients with type 2 diabetes mellitus (DM). The purpose of this study was to investigate how type 2 DM patients were affected by the lockdown.

METHOD

Type 2 DM patients unable to attend regular follow-ups due to lockdown over a 75-day period between March and June 2020 and who again attended polyclinic follow-up when the lockdown was lifted were included in the study. These patients' glycemic control and weight status were compared with the pre-lockdown period. In addition, patients' general habits, and adherence to diet and exercise were evaluated, while their general health was assessed using the Short-Form 36-item survey.

RESULT

The research involved 101 type 2 DM patients, 57 men (56.5%) and 44 women (44.5%), with a mean age of 55 ± 13. Patients' mean pre-lockdown weight was 84.7 ± 16.4 kg, rising to 85.5 ± 16.8 kg post-lockdown, although the increase was not statistically significant (p = 0.781). In terms of glycemic parameters, Hba1c rose from 7.67 ± 1.76 to 8.11 ± 2.48, and fasting glucose from 157.9 (83-645) mg/dl to 163.2 (84-550) mg/dl, none of which were statistically significant (p = 0.253, p = 0.079, respectively).

CONCLUSION

In addition to weight gain among type 2 DM patients during the Covid 19 lockdown, statistically insignificant increases were also observed in such glycemic parameters. This was a small sample and further studies with larger sample are needed.
