Table 2.
Vitamin D status among the Fok-I genotypic groups before and after 12 months of vitamin D supplementation.
| Vitamin D status (N = 199) | TT (N = 113) | TC (70) | CC (16) | |||
|---|---|---|---|---|---|---|
| Baseline | Follow-up | Baseline | Follow-up | Baseline | Follow-up | |
| Desirable | 0 (0.0) | 14 (12.4) | 1 (1.4) | 9 (12.9) | 0 (0.0) | 0 (0.0) |
| Sufficiency | 10 (8.8) | 66 (58.4) | 4 (5.7) | 25 (35.7) | 1 (6.3) | 1 (6.3) |
| Deficiency | 103 (91.2) | 33 (29.2) | 65 (92.9) | 36 (51.4) | 15 (93.8) | 15 (93.8) |
Note: Σ2 test showed a Ptrend of 0.626 at baseline; Ptrend at 12-month follow-up is < 0.0001. Data is presented as frequencies (%). Deficiency: Serum 25(OH)D level < 50 nmol/l. Sufficiency: Serum 25(OH)D level between 50 to 75 nmol/l. Desirable: Serum 25(OH)D level > 75 nmol/l.
