In the above article published in the September 2009 issue of the Journal, an error concerning how the intake of vitamin D was reported was identified by a reader. The authors would like to address this matter as follows:

The vitamin D intakes of our subjects was reported as mcg but should have been presented in International Units (IU), as seen in Table 5 of the article. This error led to a significant over-estimation of the vitamin D intake, as the conversion factor is 40 IU to 1 mcg. The mean intakes in IU (SE) of all subjects (n = 324) was 202.3 IU (11.6) from dietary intakes alone, and 222.1 IU (13.3) from diet with supplementation. Compared to a recommended DRI requirement of 200 IU (based on the needs of 18- to 50-year-olds), the female subjects on average did not meet their DRI from their diet and from their diet with supplementation which was determined to be 172.2 IU (13.3) and 184.8 IU (15.0), respectively. However, the male subjects met their DRI with 252.6 IU (21.6) from diet alone as well as from their dietary intake with supplementation with 286.3 IU (25.7). In conclusion, overall the 324 subjects' mean intake of vitamin D was sufficient relative to diet and diet with supplementation. However, on average, the female subjects failed to meet their daily requirement for vitamin D from diet as well as from diet with supplements.
