Vitamin D insufficiency and deficiency can be diagnosed with measurements of serum 25-hydroxyvitamin D (25OHD). Most vitamin D is derived from sunlight (80%), so serum 25OHD levels are lowest in late winter and early spring. Dietary vitamin D in North America is small, about 100 to 200 IU daily. A recent review of the literature shows many association studies relating vitamin D deficiency and insufficiency to several diseases. Large randomized trials of vitamin D are underway and soon there may be answers as to whether vitamin D is clinically effective and what level of serum 25OHD is necessary.

Attention Score in Context
Attention Score in Context
This research output has an Altmetric Attention Score of 1. 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 31 January 2021.
All research outputs
#24,783,232
of 34,400,738 outputs
Outputs from Endocrinology and metabolism clinics of North America (Print)
#826
of 1,054 outputs
Outputs of similar age
#248,163
of 359,974 outputs
Outputs of similar age from Endocrinology and metabolism clinics of North America (Print)
#7
of 13 outputs
Altmetric has tracked 34,400,738 research outputs across all sources so far. This one is in the 19th percentile – i.e., 19% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,054 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 12.0. This one is in the 19th percentile – i.e., 19% 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 359,974 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 23rd percentile – i.e., 23% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 13 others from the same source and published within six weeks on either side of this one. This one is in the 46th percentile – i.e., 46% of its contemporaries scored the same or lower than it.
