| Abstract |
We investigated the association between dietary, supplementary and total vitamin D intake and incident psoriasis in women. A prospective study was performed of 70,437 US female nurses aged 47-74 enrolled in the Nurses' Health Study who did not have psoriasis at baseline in 1994 and who completed semi-quantitative food frequency questionnaires in 1994, 1998, 2002 and 2006. The incidence of clinician-diagnosed psoriasis was ascertained and validated by self-reported questionnaires. 502 confirmed incident psoriasis cases were documented during 973,057 person-years of follow-up from 1994 June to 2008 June. Association between vitamin D intake and incident psoriasis was assessed using multivariable-adjusted cox regression analysis. After adjusting for age, smoking, body mass index, calorie intake, UV flux, exercise and alcohol use, there was no significant association between vitamin D intake (dietary, supplementary and total vitamin D) and the risk of incident psoriasis. Compared with women whose dietary vitamin D intake was <100 IU/day, multivariate relative risks for psoriasis was 1.13 (95 % CI 0.66-1.92) for ≥400 IU/day (P trend = 0.88). The multivariate relative risk for women who took supplementary vitamin D ≥400 IU/day was 1.18 (95 % CI 0.88-1.58) compared with women who did not take supplementary vitamin D. The multivariate risk for women who had total vitamin D intake of 300-399 IU/day was no different than at higher and lower doses of vitamin D intake. Our study does not support preventive roles of dietary or supplemental vitamin D intake for incident psoriasis. |

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 14 September 2015.
All research outputs
#13,396,317
of 22,731,677 outputs
Outputs from Archives of Dermatological Research
#870
of 1,321 outputs
Outputs of similar age
#110,796
of 211,390 outputs
Outputs of similar age from Archives of Dermatological Research
#7
of 13 outputs
Altmetric has tracked 22,731,677 research outputs across all sources so far. This one is in the 39th percentile – i.e., 39% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,321 research outputs from this source. They receive a mean Attention Score of 4.8. This one is in the 32nd percentile – i.e., 32% 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 211,390 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 46th percentile – i.e., 46% 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.
