Abstract

Vitamin D (Vit D) is suggested to play a role in the regulation of physical function as well as in depression. Since, Vit D deficiency is common in patients with heart failure (HF), this study aims to explore if Vit D levels are associated with depressive symptoms and if this association is mediated by the patients' physical function. 506 HF patients (mean age 71, 38% women) were investigated. Depressive symptoms and physical function were measured with the Centre for Epidemiological Studies Depression Scale and the physical function scale from the RAND-36. Vit D was measured in blood samples RESULTS: At baseline there was no relationship between depressive symptoms and Vit D levels. However, at 18months follow-up 29% of patients with Vit D <50nmol/l at baseline had depressive symptoms compared 19% of those with Vit D levels >50nmol/l (p<0.05). Only in patients with Vit D <50nmol/l, Vit D correlated significantly to physical function and depressive symptoms (r=.29, p<0.001 and r=.20, p<0.01). In structural equation modelling an indirect association between Vit D and depressive symptoms was found, mediated by physical function (B=0.20). This association was only found in patients with Vit D levels <50nmol/l. In HF patients with Vit D <50nmol/l, Vit D is associated to depressive symptoms during follow-up and this association is mediated by physical function. This relationship is not found in patients with Vitamin D level >50nmol/l.

Attention Score in Context

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 26 January 2016.
All research outputs
#16,045,990
of 25,368,786 outputs
Outputs from International Journal of Cardiology
#4,150
of 7,535 outputs
Outputs of similar age
#219,214
of 401,526 outputs
Outputs of similar age from International Journal of Cardiology
#51
of 136 outputs
Altmetric has tracked 25,368,786 research outputs across all sources so far. This one is in the 34th percentile – i.e., 34% of other outputs scored the same or lower than it.
So far Altmetric has tracked 7,535 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.0. This one is in the 42nd percentile – i.e., 42% 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 401,526 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 42nd percentile – i.e., 42% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 136 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 60% of its contemporaries.
