Abstract

Background: Vitamin D deficiency is common among children and adolescents and can be affected by several factors such as puberty and obesity.

Objective: The aim of this study was to evaluate vitamin D status in children and adolescents and to analyse the influence of puberty and obesity on its level.

Method: A cross-sectional study was carried-out, in which clinical and biochemical data were gathered from 384 healthy children and adolescents between May 2019 to May 2020.

Results: 220 females and 164 males were enrolled (aged 7-16 years; mean ± SD: 11 ± 2.5). Vitamin D deficiency was found in 49% of the total cases and was significantly more prevalent in females than males (33.1% in female; 15.9% in male, P < .001). Mean vitamin D level was lower in obese children compared with non-obese (P < .001). Non-obese group had significantly higher levels of vitamin D in Tanner stage IV of puberty than obese individuals (20.1 ± 17.0 vs 5.4 ± 2.0) (P = .03). Vitamin D levels were significantly lower in females than males only in Tanner stage II (12.3 ± 9.0 vs 19.6 ± 16.6) (P = .005). The lowest level of Vitamin D was in Tanner stage Ⅳ-Ⅴ in boys and in Tanner stage Ⅱ-Ⅲ in girls (P < .001).

Conclusion: Puberty is an additional risk factor for vitamin D deficiency especially in girls and obese children. This increased risk, together with the fact that most important time for building a proper skeleton is during childhood and adolescent, makes it essential to monitor vitamin D in these age groups.

儿童和青少年维生素D缺乏:青春期和肥胖对维生素D状况的影响。

背景:维生素D缺乏症在儿童和青少年中很常见，可能受到青春期和肥胖等多种因素的影响。目的:本研究的目的是评估儿童和青少年的维生素D水平，并分析青春期和肥胖对其水平的影响。方法:采用横断面研究方法，收集2019年5月至2020年5月384例健康儿童青少年的临床及生化资料。结果:纳入220名女性和164名男性(年龄7-16岁;平均值±SD: 11±2.5)。在所有病例中，有49%的人缺乏维生素D，女性的患病率明显高于男性(女性为33.1%;男性15.9%，P < 0.001)。肥胖儿童的平均维生素D水平低于非肥胖儿童(P < 0.001)。非肥胖组青春期Tanner期维生素D水平显著高于肥胖组(20.1±17.0 vs 5.4±2.0)(P = 0.03)。维生素D水平仅在Tanner II期女性明显低于男性(12.3±9.0 vs 19.6±16.6)(P = 0.005)。男孩Tanner期Ⅳ~Ⅴ、女孩Tanner期Ⅱ~Ⅲ维生素D水平最低(P < 0.001)。结论:青春期是维生素D缺乏的另一个危险因素，尤其是在女孩和肥胖儿童中。由于风险增加，再加上儿童和青少年是骨骼发育最重要的时期，因此监测这些年龄段的维生素D至关重要。
