Key Points

• Question Was there a change in the incidence of diabetes in children and adolescents after the onset of the COVID-19 pandemic?
• Findings In this systematic review and meta-analysis of 42 studies including 102 984 youths, the incidence of type 1 diabetes was higher during the COVID-19 pandemic compared with before the pandemic.
• Meaning The findings suggest the need to elucidate possible underlying mechanisms to explain temporal changes and increased resources and support for the growing number of children and adolescents with diabetes.

Importance There are reports of increasing incidence of pediatric diabetes since the onset of the COVID-19 pandemic. Given the limitations of individual studies that examine this association, it is important to synthesize estimates of changes in incidence rates.

Objective To compare the incidence rates of pediatric diabetes during and before the COVID-19 pandemic.

Data Sources In this systematic review and meta-analysis, electronic databases, including Medline, Embase, the Cochrane database, Scopus, and Web of Science, and the gray literature were searched between January 1, 2020, and March 28, 2023, using subject headings and text word terms related to COVID-19, diabetes, and diabetic ketoacidosis (DKA).

Study Selection Studies were independently assessed by 2 reviewers and included if they reported differences in incident diabetes cases during vs before the pandemic in youths younger than 19 years, had a minimum observation period of 12 months during and 12 months before the pandemic, and were published in English.

Data Extraction and Synthesis From records that underwent full-text review, 2 reviewers independently abstracted data and assessed the risk of bias. The Meta-analysis of Observational Studies in Epidemiology (MOOSE) reporting guideline was followed. Eligible studies were included in the meta-analysis and analyzed with a common and random-effects analysis. Studies not included in the meta-analysis were summarized descriptively.

Main Outcomes and Measures The primary outcome was change in the incidence rate of pediatric diabetes during vs before the COVID-19 pandemic. The secondary outcome was change in the incidence rate of DKA among youths with new-onset diabetes during the pandemic.

Results Forty-two studies including 102 984 incident diabetes cases were included in the systematic review. The meta-analysis of type 1 diabetes incidence rates included 17 studies of 38 149 youths and showed a higher incidence rate during the first year of the pandemic compared with the prepandemic period (incidence rate ratio [IRR], 1.14; 95% CI, 1.08-1.21). There was an increased incidence of diabetes during months 13 to 24 of the pandemic compared with the prepandemic period (IRR, 1.27; 95% CI, 1.18-1.37). Ten studies (23.8%) reported incident type 2 diabetes cases in both periods. These studies did not report incidence rates, so results were not pooled. Fifteen studies (35.7%) reported DKA incidence and found a higher rate during the pandemic compared with before the pandemic (IRR, 1.26; 95% CI, 1.17-1.36).

Conclusions and Relevance This study found that incidence rates of type 1 diabetes and DKA at diabetes onset in children and adolescents were higher after the start of the COVID-19 pandemic than before the pandemic. Increased resources and support may be needed for the growing number of children and adolescents with diabetes. Future studies are needed to assess whether this trend persists and may help elucidate possible underlying mechanisms to explain temporal changes.

VitaminDWiki – Overview Diabetes and vitamin D contains

• Diabetes is 5X more frequent far from the equator
• Children getting 2,000 IU of vitamin D are 8X less likely to get Type 1 diabetes
• Obese people get less sun / Vitamin D - and also vitamin D gets lost in fat
• Sedentary people get less sun / Vitamin D
• Worldwide Diabetes increase has been concurrent with vitamin D decrease and air conditioning
• Elderly get 4X less vitamin D from the same amount of sun
      Elderly also spend less time outdoors and have more clothes on
• All items in category Diabetes and Vitamin D 551 items: both Type 1 and Type 2

Vitamin D appears to both prevent and treat diabetes

• Appears that >2,000 IU will Prevent
• Appears that >4,000 IU will Treat , but not cure
• 90% less T2 Diabetes in the group having lots of Vitamin D
• Appears that Magnesium helps both Prevention and Treatment
• Many diabetics would be better treated if Gut-Friendly Vitamin D were used

This increase in T1 may be due to COVID's deactivation of Vitamin D Receptor

COVID protects itself by deactivation of the VDR.
COVID probably fails to re-activate the VDR when it leave the body

• Excess deaths - 5 possible reasons - many studies
  • primary suspect: deactivation of Vitamin D Receptor
  • There are 37 studies in both Virus and Vitamin D Receptor categories
• Type 1 diabetes 1.6 times more likely if a Vitamin D Receptor problem – Feb 2017
• Type 1 Diabetes association with poor Vitamin D Receptor: 39 studies – April 2017
