Status and influential factors of vitamin D among children aged 0 to 6 years in a Chinese population.

ABSTRACT: BACKGROUND:Vitamin D insufficiency and deficiency in childhood are common. However, the status and influential factors of vitamin D during different ages are not clear. This study aimed to survey vitamin D concentrations in children aged 0 to 6?years and explore its influential factors. METHODS:A total of 6953 children were recruited in Wuxi City of East China from January to December in 2016. Enzyme-linked immunosorbent assay was used to determine the serum concentrations of 25-hydroxyvitamin D [25(OH)D]. RESULTS:The median vitamin D concentrations in the infant group (0-1?years of age) was 69.40?nmol/L, which were higher than that in both the toddlerhood group (1-3?years of age; 62.30?nmol/L) and the preschool group (3-6?years of age; 50.85?nmol/L). In addition, the median vitamin D concentrations were 71.70?nmol/L in summer, which was higher than that in spring (64.25?nmol/L), autumn (62.95?nmol/L) and winter (64.10?nmol/L). However, no difference was observed between genders (P?=?0.974). Furthermore, the prevalence of vitamin D deficiency (
