The association between dietary nutrient intake and GC dose change (decreased vs unchanged/increased) between –1 year to inclusion, inclusion to +1 year and −1 year to +1 year
| Time period | Nutrient* | OR† | 95% CI | p Value |
|---|---|---|---|---|
| −1 year to Inclusion | Beta-carotene (µg) | 0.29 | 0.10 to 0.88 | 0.029 |
| Inclusion to +1 year | Vitamin B12 (µg) | 3.72 | 1.08 to 12.84 | 0.038 |
| −1 year to +1 year | Fatty acid C18:2 (g) | 0.30 | 0.10 to 0.90 | 0.031 |
| Vitamin B6 (µg) | 0.29 | 0.10 to 0.87 | 0.027 | |
| Calcium (mg)‡ | 5.36 | 1.64 to 17.52 | 0.005 | |
| Vitamin B12 (µg) | 3.20 | 1.08 to 9.43 | 0.035 |
*All nutrients are dichotomised into lower (<median) intake and higher (>median) intake. Low intake=referent group.
†OR adjusted for age and gender.
‡After adjusting for calcium/vitamin D supplementation: OR=5.60 (95% CI 1.67 to 18.76).
GC, glucocorticoid.
