Vitamin D is a fat-soluble secosteroid prohormone that is produced on the skin by contact with sunlight. Through various metabolic changes in the body, it transforms into a hormone known as calcitriol, with a key role in the calcium and phosphate metabolism (1). Vitamin D serves plenty of functions in the body. Therefore, its deficiency may cause musculoskeletal symptoms such as bone pain, muscle weakness, gait difficulty, skeletal deformity, in addition to extraskeletal symptoms such as autoimmune diseases, cardiovascular diseases, and neuropsychiatric diseases (2).
Down Syndrome occurs as a result of trisomy, which occurs due to an extra copy of the whole or part of the long arm of chromosome 21 and is the most commonly known cause of delay in development. DS affects 1 in every 787 liveborn babies (3). DS is often accompanied by distinctive craniofacial features, congenital heart disease and immune, musculoskeletal and endocrine system abnormalities (4,5).
In patients with this syndrome, various environmental and hormonal factors such as hypotonia, low physical activity, poor calcium and vitamin D intake, intrauterine growth restriction, hypogonadism and thyroid dysfunction may contribute to bone mass and quality (6,7). Among all the others, vitamin D may have a crucial role in the health of these people. Vitamin D levels differ with many factors, including exposure to sunlight, dietary intake, and supplement use (8,9).
There is a lack of scientific evidence on the prevalence and severity of vitamin D deficiency in children with DS. Hence, this study aimed to determine vitamin D deficiency in children with DS, from infancy to toddler and particularly during the preschool period, and to raise awareness on the matter.
