摘要

Information on vitamin D deficiency in prepubertal children is scarce. The authors studied calcium intake, sunlight exposure, serum calcium, alkaline phosphatase, 25-hydroxyvitamin (25OHD), and intact parathormone (iPTH) in the children (N = 135) attending the pediatric endocrinology clinic (declared normal after evaluation) and their healthy siblings. Serum 25OHD < 12 ng/mL was frequent (55.6%) and median (IQR) 25OHD lower [10.1 (11.4) ng/mL] in pubertal (n = 36) versus prepubertal (n = 99) children [36.4% (p < 0.05), 15.5 (13.2) ng/mL (p < 0.001)]. Girls had lower 25OHD [12.33 (10.32)] vs. [15.83 (13.37) ng/mL, p < 0.05], calcium intake [517.20 (405.5) vs. 623.6 (430.5) mg, p < 0.05], and minutes of sunlight exposure [MSE, 38.55 (42.86) vs. 63.4 (66.8) min, p < 0.01] than boys. MSE and body surface area (BSA) exposed were significant associations of 25OHD in a multivariate model. Vitamin D deficiency in children, both pubertal and prepubertal, assumes public health importance in the authors' region. Girls are at higher risk. Duration of sunlight exposure and BSA are modifiable factors.
