摘要

BACKGROUND/OBJECTIVES: Vitamin D deficiency in children remains a global concern. Although literature exists on the vitamin D status and its risk factors among children in the Middle East, findings have yielded mixed results, and large, representative community studies are lacking. SUBJECTS/METHODS: In a nationally representative survey of 1077 Jordanian children of preschool age (12-59 months) in Spring 2010, we measured 25(OH)D-3 concentrations by liquid chromatography-tandem mass spectrometry and calculated prevalence ratios for deficiency associated with various factors. RESULTS: Results showed 19.8% (95% confidence interval (Cl): 16.4-23.3%) deficiency ( < 12 ng/ml) and 56.5% (95% Cl: 52.0-61.0%) insufficiency ( < 20 ng/ml). In adjusted models, prevalence of deficiency was higher for females compared with males (prevalence ratio (PR) = 1.74, 95% Cl: 1.22-2.47, P=0.002) and lower for children 24-35 months of age (PR=0.64, 95% Cl: 0.44-0.92, P=0.018) compared with children 12-23 months of age. In rural areas, there was no difference in prevalence of vitamin D deficiency between those whose mothers had/did not have vitamin D deficiency (P=0.312); however, in urban areas, prevalence of vitamin D deficiency was 3.18 times greater among those whose mothers were vitamin D deficient compared with those whose mothers were not deficient (P=0.000). CONCLUSIONS: Vitamin D deficiency and insufficiency pose significant public health problems in Jordanian children with female children disproportionately affected. Strong associations between vitamin D status in children and urban residency and maternal vitamin D status suggest that the behaviors related to sun exposure in urban mothers likely also affect the sun exposure and thus vitamin D status of their children.
