title: Serum 25(OH)D3 and ultraviolet exposure of residents in an old people's home in Germany.
abstract: The 25(OH)D3 serum levels of 31 and 29 residents of an old people's home in Dresden were determined in February and in August 1991. The mean 25(OH)D3 levels in winter were below 10 ng/ml. Bedridden patients did not reach this level even in summer. Polysulphone films are useful indicators of a deficiency of ultraviolet light, which can result in a subsequent vitamin D deficiency.
