Low vitamin D deficiency in Irish toddlers despite northerly latitude and a high prevalence of inadequate intakes

Purpose While reports of inadequate vitamin D intakes among young children are widespread, data on the prevalence of vitamin D deficiency are inconsistent. We aimed to quantify vitamin D intake and serum 25-hydroxyvitamin D [25(OH)D] concentrations in children aged 2 years in the prospective Cork BA...

Description
Summary:Purpose While reports of inadequate vitamin D intakes among young children are widespread, data on the prevalence of vitamin D deficiency are inconsistent. We aimed to quantify vitamin D intake and serum 25-hydroxyvitamin D [25(OH)D] concentrations in children aged 2 years in the prospective Cork BASELINE Birth Cohort Study. Methods Serum 25(OH)D was analysed using UPLC-MS/MS in 741 children living in Cork, Ireland (51°N). Two-day weighed food diaries were collected in 467 children, and 294 provided both a blood sample and a food diary. Results Mean (SD) 25(OH)D concentrations were 63.4 (20.4) nmol/L [winter: 54.5 (19.9), summer: 71.2 (17.5)]. The prevalence of vitamin D deficiency (
