Background summary
Vitamin D deficiency is common in older persons, in particular in residents of
nursing homes. It may lead to muscle weakness, bone loss and therefore to
fractures. Vitamin D supplementation decreases the risk of falls and fractures.
Vitamin D status in the elderly can be improved by oral vitamin D
supplementation or by ultraviolet irradiation. Ultraviolet irradiation may have
an extra positive effect on well being and health. While using ultraviolet
irradiation vitamin D intoxication is negligible.
Although the elderly skin is still capable of producing vitamin D, it is not
known whether in elderly nursing home residents, weekly half body irradiations
can lead to adequate serum 25(OH)D levels.
Study objective
The aim of this pilot study is to investigate in a Dutch psycho geriatric
nursing home population whether weekly half body UVB irradiation after
showering is an efficient and in daily practice feasible method for the
supplementation of vitamin D.
Study design
pilot study on the effect of weekly half-body ultraviolet irradiation at half
the *minimal erythemal dose*(MED) by using two 100W/12 UVB lamps: a so called
*dose adequacy study*
Intervention
half-body UVB irradiation after showering, during 8 weeks, once a week with 1
SED = 0,5 MED
Study burden and risks
burden and risks are negligible: the two minutes UVB irradiaton takes place
after showering. extra tansfers or not necesary/ 4 times blood sampling
