Dependent variable: 25(OH)D status (ng/mL). = 0.19, adjusted = 0.16, F (7, 142) = 5.0, and P < 0.001. 1Log transformed variables. 2Phytate : calcium ratio = mmol/day phytate intake/mmol/day calcium intake. 3% body surface area exposed to sunlight × hours of sun exposure/week. Higher values indicate greater exposure to sunlight. Time of day (24 hours) refers to the time of the day to sun exposure in 24-hour format. |
