Is avoidance of sunlight a cause of fractures of the femoral neck in elderly Saudis?
A study of the frequency of admitted cases of femoral neck fractures to Riyadh Central Hospital, Riyadh, Saudi Arabia, showed admission of 95 patients over 40 years of age in a period of one year. The male to female ratio was 64% males to 36% females. Vitamin D nutritional status of patients with fractures of the neck of the femur expressed as 25-(OH)D3 was significantly lower (5.9 +/- 2.9 ng/ml) than of controls (9.7 +/- 4.7 ng/ml). Comparison of the housing types of both patients and controls showed that those living in traditional mud houses have significantly lower levels of 25-(OH)D3 than those occupying villas or flats. A third group of patients with low stores of vitamin D were exposed to natural ultraviolet light for a short period. This resulted in a significant increase in the levels of serum 25-(OH)D3 and a decrease in alkaline phosphatase activity. It is concluded that low levels of serum 25-(OH)D3 may play a role in the pathogenesis of femoral neck fractures in elderly Saudis and this may be due to minimal exposure to natural ultraviolet irradiation.

Sunlight and protection of the skin.
Sunburn, wrinkling and malignancies are the frequent results of excessive sun exposure. Photosensitivity and photoallergic or phototoxic reactions are less commonly observed. Sunscreens containing para-aminobenzoic acid (PABA), PABA esters and benzophenones offer substantial protection, allowing even fair-skinned persons to participate freely in outdoor activities. These products are now rated and assigned a sun protection factor (SPF). Their routine use should be encouraged.
