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. Results Mean s-25(OH)D was 56·8 ( sd 12·5) nmol/l and positively associated with fat-free mass index ( P =0·014). Children being active 6–7 h/week had 5·6 (95% CI 1·1, 10·0) nmol/l higher s-25(OH)D than less active children ( P =0·014). Children seeking shade sometimes or rarely/never had 7·0 (95% CI 1·2, 12·9; P =0·018) and 7·2 (95% CI 0·8, 13·6; P =0·028) nmol/l higher s-25(OH)D, respectively, than children always/often seeking shade. Pre-school children had more sun-safe behaviour than school children in terms of use of a hat, sunscreen and sunscreen sun protection factor ( P P =0·014) nmol/l higher s-25(OH)D v . always/often ( P interaction =0·019). Vitamin D intake was not associated with s-25(OH)D ( P =0·241). 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
