Table 2. Vitamin D and calcium intake and percent below the Estimated Average Requirements of traditional food eaters and non-traditional food eaters a among Inuit and Inuvialuit women of child-bearing age (19–44 years) in Nunavut and the Northwest Territories.
| TFE (n = 99) | NTFE (n = 104) | Total (n = 203) | p-valueb | |
| Vitamin D (µg/day) c | ||||
| Mean ± SD | 7.11±7.47 | 4.88±4.72 | 5.97±6.30 | 0.02 |
| Median (P25-P75) | 5.13 (3.05–8.39) | 3.50 (2.42–5.63) | 4.21 (2.62–7.11) | |
| n (%) below EAR d | 81 (82.0) | 95 (91) | 176 (87.0) | |
| Calcium (mg/day) c | ||||
| Mean ± SD | 1428.0±649.0 | 1120.0±565.0 | 1270.0±625.0 | 0.0005 |
| Median (P25–P75) | 1299.0 (1002.4–1800.7) | 992.0 (688.9–1393.0) | 1154.0 (764.6–1641.2) | |
| n (%) below EAR d | 18 (18.0) | 36 (35.0) | 54 (27.0) |
EAR, estimated average requirement; P25–P75, 25 percentile and 75 percentile; NTFE, non-traditional food eaters; SD, standard deviation; TFE, traditional food eaters.
Traditional eaters consumed >300 g and non-traditional eaters consumed ≤300 g of traditional foods/day.
Non-parametric Wilcoxon rank-sum test was performed to compare differences in intake between TFE and NTFE.
The individual intake goal for vitamin D and calcium is referred to as the Recommended Dietary Allowance level. For Vitamin D and calcium the recommended intakes are15 µg/day and 1,000 mg/day respectively for women aged 19–50 years.
Adequacy was determined using the Estimated Average Requirements levels of 10 µg/day vitamin D and 800 mg/day for calcium for women aged 19-50 years.
