Vitamin D has an essential role in bone growth and metabolism. Currently, its role has been investigated in different diseases. It is high prevalence of vitamin D deficiency in the world, particularly in developing countries.

Objectives

The aim of this study is to investigate the prevalence of vitamin D deficiency in children of 1 - 6 years old and its relation with their age, sex and body mass index.

Methods

This study was conducted in pediatric clinic of Javaheri Hospital in Tehran, from 2016 to 2017. The study population was children of 1 - 6 years old presenting to the pediatric clinic for routine examination or treatment. The collected data included age, gender, height, weight, and serum 25-hydroxy vitamin D level.

Results

Of the total population of 288 children, 47.2% were female and 52.8% were male. The prevalence of vitamin D deficiency was 51%, while 4.51% had severe deficiency (level of vitamin D < 10 ng/mL). The relation between the level of vitamin D and variables of gender, height, weight, and body mass index was not statistically significant. Nonetheless, the level of vitamin D had a statistically significant relation with age such that, serum level of 25(OH) vitamin D reduced by 3.47 ng/mL for every one year of age (P < 0.001).
