目的：为了评估维生素D的膳食来源，摄入量和25-羟基维生素D的状态及其与墨西哥children.Design的个人和社会人口特征的关联：从2695名1-11岁的儿童从墨西哥国家健康和营养调查（2012年）获得的数据进行了分析。饮食由141项FFQ评估。25-结果：学龄前儿童平均维生素D摄入量为3.38（SE0.09）μ g/d（135.2（SE3.6）IU/d），学龄期儿童平均维生素D摄入量为2.85（SE0.06）μ g/d（114.0（SE2.4）IU/d）。牛奶占学龄前儿童维生素D摄入量的64.4%和学龄儿童的54.7%。维生素D缺乏症（血清25-羟维生素D < 50 nmol/l）在学龄前儿童中为25.9%，在学龄儿童中为36.6%。超重/肥胖学龄儿童与正常体重儿童相比，维生素D缺乏的风险更高（OR = 2.23; 95% CI 1.36，3.66; P < 0.05）。结论：墨西哥儿童维生素D摄入量低，牛奶是维生素D的主要来源。维生素D缺乏症很常见，与学龄儿童超重有关。
Objective: To assess vitamin D dietary sources, intake and 25-hydroxyvitamin D status and their association with individual and sociodemographic characteristics in Mexican children.Design: Data obtained from 2695 children aged 1-11 years from the Mexican National Health and Nutrition Survey (2012) were analysed. Diet was assessed by a 141-item FFQ. 25-Hydroxyvitamin D was measured by a chemiluminescent assay.Results: Mean vitamin D intake was 3.38 (SE 0.09) mu g/d (135.2 (SE 3.6) IU/d) among pre-school children and 2.85 (SE 0.06) mu g/d (114.0 (SE 2.4) IU/d) in school-age children. Milk accounted for 64.4% of vitamin D intake in pre-school children and 54.7% in school-age children. Vitamin D deficiency (serum 25-hydroxyvitamin D < 50 nmol/l) was 25.9% in pre-schoolers and 36.6% in school-age children. Overweight/obese school-age children had a higher risk of vitamin D deficiency compared with normal-weight children (OR = 2.23; 95% CI 1.36, 3.66; P < 0.05).Conclusions: Vitamin D intakes are low in Mexican children, and milk is the main source of the vitamin. Vitamin D deficiency is common and associated with overweight in school-age children.
