Abstract

In a group of thirty-six non-housebound normal people aged 70 to 88 years living independently in their homes, mean serum-25-hydroxy-vitamin-D (±1 S.D.) was 8·62±3·08 ng/ml in midwinter and had risen to 14·13±4·90 ng/ml the following September. These values were lower and the seasonal variation was less than previously found in healthy young British adults.

    The association of serum 25(OH)D and UV radiation (UVR) exposure has been demonstrated in several epidemiological studies [3,4]. Two important demonstrations of this correlation are the dependence of serum vitamin D on seasonality and on latitude [5–7]. Accordingly, during migration from tropical latitudes, Homo sapiens has been subjected to a strong selective pressure in order to adapt to changing geographical and climate conditions at low UVB irradiance, as clearly demonstrated by fascinating studies about evolution of human skin color [8].

    One study did report a 13–19% within-individual variability in 25(OH)D (54), causing the authors to question the clinical utility of a single 25(OH)D measurement in an individual patient. However, it seems likely that this conclusion reflects the well-known seasonal 25(OH)D change and not day-to-day variability (55). Given the relatively long half-life of 25(OH)D, day-to-day variability seems unlikely to impact this measurement.
