The list of risk factors for hypovitaminosis D in the Conclusion (first sentence, second paragraph) should include "higher latitude" rather than "lower latitude".The online version of the original article can be found at http://dx.doi.

25-Hydroxyvitamin D in Canadian adults: biological, environmental, and behavioral correlates

“…This finding concurs with other Canadian studies [12,13,15,[38][39][40] and with international [32] findings. The population of Canadians with darker skin pigmentation now stands at one in five Canadians, and the need for people of darker skin to take more vitamin D is increasingly recognized [41].…”

“…In this study, levels of serum 25(OH)D <75 nmol/L [22] were evident in 59% [11,12,15,31] and in other countries [32]. Consequently, it is likely that a large proportion of Canadians would have suboptimal vitamin D status at some point during the year.…”

High prevalence of vitamin D deficiency among healthy Saudi Arabian men: relationship to bone mineral density, parathyroid hormone, bone turnover markers, and lifestyle factors

“…The latter indicates that commonly used supplement doses are inadequate to ensure optimal vitamin D nutrition. Taken together with previous studies in Caucasians [17][18][19][20], Asians [21][22][23][24][25], and other men [17,26,27] confirm the observation that vitamin D deficiency and/or insufficiency is endemic among populations of the world, and countries with sunny climates are no exception.…”

Bone health in healthy Indian population aged 50 years and above

“…Strong positive correlation of BMI with BMD at all sites and negative correlation with PTH, ALP, and phosphates seen in the present study was also observed by several other workers [6,7,39]. There was no significant correlation observed between serum 25(OH)D and BMD at different sites which is in concordance with our earlier studies [8-11, 13, 32].…”
