Sun behaviour and physical activity associated with autumn vitamin D status in 4-8-year-old Danish children
Research output: Contribution to journal › Journal article › Research › peer-review
Objective: To explore determinants of serum 25-hydroxyvitamin D (s-25(OH)D) during autumn in young, Caucasian children not consuming vitamin D-fortified foods or supplements, and explore differences in sun behaviours between pre-school and school children.
Design: In September-October, s-25(OH)D was measured by LC-MS/MS; physical activity, sun behaviours and vitamin D intake were assessed with questionnaires.
Setting: Baseline data from the ODIN Junior trial at 55°N.
Subjects: Children aged 4-8 years (n 130), of whom 96% gave blood samples.
Conclusions: Physical activity and sun behaviours are associated with s-25(OH)D in young children. Identifying factors influencing autumn s-25(OH)D is relevant to optimize levels before sun exposure diminishes. Strategies to reduce risk of inadequacy should consider risk of skin cancer and sunburn, and could include fortification and/or vitamin D supplementation.
