Descrição: BackgroundHigh-risk groups for COVID-19, such as ethnic minorities, also experience the greatest risk for micronutrient deficiencies including Vitamin D. Vitamin D may positively impact COVID-19 prevention and treatment, however, further studies are needed to understand its role.ObjectivesTo guide further studies exploring Vitamin D and COVID-19, this study aimed to identify national nutrition surveys containing information regarding Vitamin D status, deficiency or supplementation intake.MethodsSystematic searches were performed on MedLine and an extraction template was used to collect information on surveys; country, year of data collection, Vitamin D indicators and access.Results27 national nutrition surveys were identified as collecting Vitamin D data across global countries; 8 were publicly available (open-access), 9 required applications and raw-data was not accessible (N/A) for 10. Table 1 displays survey information, including the Vitamin D indicators used. Surveys recorded either serum 25-hydroxyvitamin D (25-OHD) concentration (nmol/L) or estimated Vitamin D intake from interviews/food diaries.Additionally, Vitamin D data was rarely collected in low-income countries such as Africa. Data mapping has outlined disease reporting standards in countries and has emphasised the systematic differences between healthcare systems.Abstract 14 Table 1National nutrition surveys collecting vitamin D data Country Nutrition Survey Vitamin D Indicator Access Europe UK PHE National Diet & Nutrition Survey (NDNS) [2008–19] Serum 25-OHD concentrationSupplement intake Open France French national dietary survey (INCA1, INCA2, INCA3) [1998–2017] Serum 25-OHD concentrationSupplement intake Open Finland The Finnish National Dietary Survey in Adults and Elderly (FinDiet 2017) Serum 25-OHD concentrationEstimated intake (microgram) Application Germany Nationale Verzehrsstudie II: Estimated intake (microgram)Supplement usage Application Israel Mabat First Israeli National Health and Nutrition Survey Estimated intake (microgram) Application Netherlands Dutch National Food Consumption Survey Supplement usage Application Belgium Belgium Health Examination survey (BELHES) Estimated intake (microgram) Application Austria Austrian Nutrition Report (OSES) [2017] Serum 25-OHD concentration N/A Denmark National Survey of Dietary Habits and Physical Activity (DANSDA) Serum 25-OHD concentrationSupplement intake N/A Spain National Food Survey in the adult population, the elderly and pregnant women.

N/A – raw data not accessibleConclusionVitamin D data can be combined with COVID-19 incidence and mortality data, to explore the relationship between Vitamin D and COVID-19. Further research can explore inter-individual differences in Vitamin D requirements, optimal therapeutic doses required and how individual requirements can be determined. Findings will improve disease pathway understanding, support the generation of aetiological hypotheses and contribute to COVID-19 prevention and treatment. Substandard diagnosis and reporting in low-middle income countries underestimates disease rates, compared to high income countries. Studies investigating countries across income levels may therefore be affected by case-ascertainment bias, however also highlight where future resources should be directed to improve overall health and reduce inequalities, as well as reducing the burden of COVID-19.
