Seasonal Vitamin D Status of Healthy Schoolchildren and Predictors of Low Vitamin D Status

Abstract

Vitamin D deficiency is prevalent among healthy schoolchildren. It is noteworthy that 25(OH)D levels were significantly lower in girls and during autumn. We recommend vitamin D supplementation for children in addition to more time spent for outdoor activities for sensible sunlight exposure.

A History of Cow’s Milk Allergy Is Associated with Lower Vitamin D Status in Schoolchildren

“…Female gender has also been associated with a lower vitamin D status in other studies [19, 31]. This could be due to the finding that girls spend less time outdoors than boys, as was also seen in our study [32]. However, in our cohort, this is an unlikely explanation, as most of the 25(OH)D measurements were performed during the season when sunlight exposure outdoors is limited.…”

Prevelance of vitamin D and B12 deficiency in adolescence

“…Bu farkın dini ya da geleneksel kapalı giyim şekli yaygın olan bölgelerde, özellikle kız ergenlerde endojen D vitamini üretiminin az olması nedeniyle geliştiği düşünülmektedir. Ülkemizde yapılan bir çalışmada da kapalı giyim şekli olan ergenlerde D vitamin düze-yinin düşük olduğu gösterilmiştir (28) . Çalışmamızda cinsiyete göre D vitamin düzeyleri arasında fark bulunmamıştır.…”

Bone mineral density and vitamin K status in children with celiac disease: Is there a relation?

“…Vitamin D levels did not differ between patients with CD and healthy participants. This may be attributed to a generally low intake of vitamin D in healthy children and adolescents in Eastern Anatolia (28). Adequate vitamin D and calcium intake plays an important role in the prevention and treatment of osteoporosis.…”
