BACKGROUND
Vitamin D (VD) deficiency and childhood obesity are a public health problem in Mexico. Both are related to the development of various chronic diseases. It is important to describe and identify the main risk factors involved in VD deficiency in this population.
OBJECTIVE
To describe VD intake in obese Mexican adolescents and evaluate its association with serum 25(OH)D concentrations.
MATERIAL AND METHODS
A cross-sectional study was performed in 80 obese adolescents from Mexico City. Sociodemographic, anthropometric, dietary intake, sun exposure, and physical activity data were collected. A blood sample was taken to determine serum 25(OH)D concentrations.
RESULTS
VD deficiency and insufficiency occurred in 30% and 42.2% of adolescents. The median VD intake was 110.4 IU/day and the mean sun exposure score was 13 ± 7.5. Serum 25(OH)D levels were correlated with vitamin D intake (p = 0.010). Concentrations of 25(OH)D in serum were similar when compared between sex, sunscreen use, season, and skin type (p > 0.05).
CONCLUSIONS
VD deficiency in adolescents with obesity is high. In contrast with its dietary intake and degree of sun exposure which are considerably low. A significant association was observed between dietary VD intake and serum 25(OH)D concentrations.
背景
维生素D（VD）缺乏和儿童肥胖是墨西哥的公共卫生问题。两者都与多种慢性疾病的发生有关。描述和确定该人群中VD缺乏的主要危险因素很重要。
目的
描述肥胖墨西哥青少年的VD摄入量，并评估其与血清25（OH）D浓度的关联。
材料与方法
对来自墨西哥城的80名肥胖青少年进行了一项横断面研究。收集了社会人口统计学、人体测量学、饮食摄入量、阳光暴露和身体活动数据。采集血样以测定血清25（OH）D浓度。
结果
30%的青少年存在VD缺乏，42.2%的青少年存在VD不足。VD摄入量中位数为110.4 IU/天，平均阳光暴露评分为13±7.5。血清25（OH）D水平与维生素D摄入量相关（p = 0.010）。按性别、是否使用防晒霜、季节和皮肤类型比较时，血清中25（OH）D的浓度相似（p>0.05）。
结论
肥胖青少年中VD缺乏情况严重。相比之下，他们的饮食摄入量和阳光暴露程度相当低。观察到饮食中VD摄入量与血清25（OH）D浓度之间存在显著关联。
