Abstract

Background: Vitamin D deficiency is common among people withIntellectual and Developmental Disability (IDD) and is linked to worsehealth outcomes.Aims: To re-evaluate vitamin D testing and supplementation amonginpatients with IDD and examine any correlates with physical healthconditions including COVID-19.Method: Records of all inpatients between January 2019 and July 2020 were examined for 25-hydroxyvitamin D [25(OH)D] level, ward area, supplementation status, test seasonality, medication, and health status.Results: Mean 25(OH)D level for supplemented (800IU/day) patients was 75nmol/l (SD 20) compared to 40nmol/l (SD 19) in the nonsupplemented group (p<0.001). Thirty-eight percent of those who were inpatients during the first wave of the COVID-19 pandemic developed symptoms, but the small sample size could not establish vitamin D levels as a predictor of outcome.Conclusions: Vitamin D (800IU/day) supplementation is effective butadequacy of the nationally recommended dose of 400IU/day is unclear. Links to COVID-19 merit further research.
