“…Because of the nature of NHANES data collection, all the surveys in the north were taken during the summer, so these findings are likely to underestimate the prevalence of vitamin D insufficiency in this population. It also appears that vitamin D deficiency in some dark-pigmented groups seems to differentially affect bone-fracture risk, which is known to be low in African Americans (Holick, 2004;Whiting & Calvo, 2005a) and elevated in Aboriginal women (Leslie et al, 2004) relative to the general population. Concerning dietary practices, vitamin D intake appears to be lower in some vegetarians (Davey et al) and vegans (Outila et al) and in those who consume few dairy products or fortified foods Whiting & Calvo, 2005b).…”

A surprisingly high prevalence of vitamin D insufficiency and deficiency has recently been reported worldwide. Although very little is known about vitamin D status among athletes, a few studies suggest that poor vitamin D status is also a problem in athletic populations. It is well recognized that vitamin D is necessary for optimal bone health, but emerging evidence is finding that vitamin D deficiency increases the risk of autoimmune diseases and nonskeletal chronic diseases and can also have a profound effect on human immunity, inflammation, and muscle function (in the elderly). Thus, it is likely that compromised vitamin D status can affect an athlete's overall health and ability to train (i.e., by affecting bone health, innate immunity, and exercise-related immunity and inflammation). Although further research in this area is needed, it is important that sports nutritionists assess vitamin D (as well as calcium) intake and make appropriate recommendations that will help athletes achieve adequate vitamin D status: serum 25(OH)D of at least 75 or 80 nmol/L. These recommendations can include regular safe sun exposure (twice a week between the hours of 10 a.m. and 3 p.m. on the arms and legs for 5-30 min, depending on season, latitude, and skin pigmentation) or dietary supplementation with 1,000-2,000 IU vitamin D 3 per day. Although this is significantly higher than what is currently considered the adequate intake, recent research demonstrates these levels to be safe and possibly necessary to maintain adequate 25(OH)D concentrations.

“…First Nations peoples are the largest group of aboriginal peoples in Canada. Until the early 2000s, Canadian First Nations peoples were unidentified as a group at high risk for fracture [14]. Of clinical concern is that First Nations peoples have nearly twice the odds of experiencing a hip or spine fracture and three times greater likelihood of experiencing a wrist fracture compared to non-First Nations peoples [14].…”

“…Until the early 2000s, Canadian First Nations peoples were unidentified as a group at high risk for fracture [14]. Of clinical concern is that First Nations peoples have nearly twice the odds of experiencing a hip or spine fracture and three times greater likelihood of experiencing a wrist fracture compared to non-First Nations peoples [14]. This risk for individuals of First Nations ethnicity is known to be affected by multiple demographic variables including age, gender, income, and area of residence [15].…”

“…It is notable that Canadian Aboriginal women have a disproportionately higher rate of fractures than Caucasian women [2]. The First Nations Bone Health Study (Manitoba, Canada) reported lower BMD, related to increased bone area, after adjustment for weight in Canadian Aboriginal than Caucasian women at the distal forearm, calcaneus and whole body [3].…”

Bone mineral density (BMD) has been reported to be both higher and lower in Indigenous women from different populations. Body composition data have been reported for Indigenous Australians, but there are few published BMD data in this population. We assessed BMD in 161 Indigenous Australians, identified as Aboriginal (n=70), Torres Strait Islander (n=68) or both (n=23). BMD measurements were made on Norland-XR46 (n=107) and Hologic (n=90) dual energy X-ray absorptiometry (DXA) machines. Norland BMD and body composition measurements in these individuals, and also in 36 Caucasian Australians, were converted to equivalent Hologic BMD (BMDH) and body composition measurements for comparison.Femoral neck (FN) and lumbar spine Z-scores were high in Indigenous participants (mean FN Zscore: Indigenous men +0.98, p<0.0001 vs. mean zero; Indigenous women +0.82, p<0.0001 vs. mean zero). FN BMDH was higher in Aboriginal and/or Torres Strait Islander than Caucasian participants, after adjusting for age, gender, diabetes and height and remained higher in men after addition of lean mass to the model. We conclude that FN BMD is higher in Aboriginal and/or Torres Strait Islander Australians than Caucasian Australian reference ranges and these
