| Abstract |
The relation between serum 25-hydroxy vitamin D [25(OH)D] and bone quality is not well understood, particularly for high levels. We measured bone microarchitecture in three groups of people stratified by their serum 25(OH)D. There was a weak association of serum 25(OH)D and microarchitecture for this cross-sectional population, suggesting possible benefits to bone quality. Vitamin D plays an important role in bone and mineral metabolism, but the relation between serum 25(OH)D and bone quality is not well understood. Here, we present a cross-sectional study that investigated a convenience group of participants from an ongoing health initiative in Alberta, Canada, who have been receiving daily vitamin D supplementation. A total of 105 participants were organized into three groups based on their serum 25(OH)D levels: low (<75 nmol/L), medium (75-175 nmol/L), and high (>175 nmol/L). They were also assessed with 25(OH)D as a continuous variable. Average daily supplementation was 7670 ± 438 IU, and the change in 25(OH)D ranged from 22 to 33 % during the period of receiving supplements. We used high-resolution peripheral quantitative computed tomography measurements at the radius and tibia to assess bone microarchitecture. Microarchitectural parameters were not strongly associated with serum 25(OH)D. In the tibia, there were fewer trabeculae (TbN; p = 0.015) and a non-significant trend toward thicker trabeculae (p = 0.067) of the high group. Body mass index (BMI) was negatively associated with serum 25(OH)D levels (p < 0.001) and PTH levels (p < 0.001). There was no clinically significant relationship detected between high serum 25(OH)D and high serum calcium. These data suggest a weak relationship between serum 25(OH)D and bone microarchitecture in this population of mostly vitamin-D-sufficient participants, and there were no indications of negative effects related to the high supplementation levels. These data provided a basis to design and implement our 3-year dose-dependent randomized controlled trial investigating the effects of vitamin D supplementation on bone health outcomes. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 17 August 2015.
All research outputs
#14,807,084
of 22,797,621 outputs
Outputs from Osteoporosis International
#2,215
of 3,608 outputs
Outputs of similar age
#148,936
of 264,934 outputs
Outputs of similar age from Osteoporosis International
#47
of 88 outputs
Altmetric has tracked 22,797,621 research outputs across all sources so far. This one is in the 32nd percentile – i.e., 32% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,608 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 7.6. This one is in the 35th percentile – i.e., 35% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 264,934 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 40th percentile – i.e., 40% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 88 others from the same source and published within six weeks on either side of this one. This one is in the 42nd percentile – i.e., 42% of its contemporaries scored the same or lower than it.
