Vitamin D levels 36 ng average, and as high as 128 ng
We believe that the participants were encouraged to supplement with vitamin D
40 ng increase in vitamin D associated with fewer reported problems
- Mobility 40% fewer
- Usual activities 30% fewer
- Depression and anxiety 30% fewer

PURPOSE:
To assess how vitamin D status is associated with health-related quality of life (HRQOL) among older residents of Canada.DESIGN:
We analysed baseline data of 1,493 Canadians aged 50 years and over in Alberta on HRQOL (EQ-5D-5L) and serum 25-hydroxyvitamin D (25(OH)D) as a measure of vitamin D status. We applied multivariable regression methods to examine the association between vitamin D status and each of the five dimensions and the summary index of the EQ-5D-5L.RESULTS:
Participants with higher serum 25(OH)D levels were significantly less likely to report problems with mobility, usual activities, and depression and anxiety. Specifically, age- and gender-adjusted odds ratios for reporting problems with mobility, usual activities, and depression and anxiety were 0.58 (95 % confidence interval 0.44-0.78), 0.67 (0.50-0.89), and 0.67 (0.51-0.88) per 100 nmol/L increase in 25(OH)D, respectively. No significant associations were observed for problems with self-care and with pain and discomfort. HRQOL scores combining the responses of each of the five dimensions increased significantly with increasing serum 25(OH)D levels.CONCLUSIONS:
This is the first study to reveal the importance of vitamin D for the five dimensions of HRQOL in a community-based sample. The observed associations of vitamin D and HRQOL call for intervention studies to strengthen the evidence of the potential benefits of vitamin D supplementation for HRQOL among older adults.
