A surge of Type 1 Diabetes Mellitus among Nigerian children during the COVID-19 pandemic

Abstract

Background: A substantial increase in Type 1 Diabetes Mellitus (T1DM) has been reported globally among children following the discovery of COVID-19. This study reports a similar trend among Nigerian children.
Method: A twelve-year (2010-2021) retrospective review of T1DM cases admitted in the Paediatric wing of a tertiary hospital in South-East Nigeria.
Result: During the twelve-year study, 21 T1DM patients were seen: 9 (43%) males and 12 (57%) females. Approximately 60% of these cases presented during the pandemic (2020-2021). The mean age of subjects with T1DM was 10.5 ± 4.1 years, with females being slightly older than the male subjects (11.6 ± 3.7 years vs 9.2 ± 4.3 years respectively; p=0.176). Prior to the pandemic, females were significantly older than males (11.6 ± 3.7 years vs 4.5 ± 2.1 years respectively; p=0.042), but no age difference was observed during the pandemic (11.6 ± 4.1 years vs 10.4 ± 3.9 years respectively; p=0.597). 80% of all males in this study were seen during the pandemic and were older than the males seen before the pandemic (10.4 ± 3.9 years vs 4.5 ± 2.1 years; p=0.078). Following adjustments for age and gender, older children and males had an increased odd of developing T1DM during the pandemic but this was not statistically significant.
Conclusion: This study highlights the need for increased awareness and high index of suspicion of T1DM among children during this pandemic. In the interim, more robust multi-centre studies are required to investigate the underlying relationship between COVID-19 and T1DM.
