The aim of this narrative review is to present up-to-date information about the impact of vitamin D deficiency (VDD) on the health status of infants in their first year of life. Vitamin D is indispensable for skeletal growth and bone health, and emerging research suggests that it may also have significant roles in maternal and fetal health. VDD affects a large proportion of infants according to current guidelines. However, its prevalence varies depending on geographic location, skin pigmentation, and the time of year. Based on current guidelines for normal vitamin D levels and recommended daily intake, studies suggest that VDD is a global health issue with potentially significant implications for those at risk, especially infants. Our understanding of the role of vitamin D has improved significantly in the last few decades. Systematic reviews and meta-analyses investigating the effect of vitamin D on preterm birth, low birth weight, anthropometric parameters, and health outcomes such as infectious diseases in infants, have found conflicting or inconsistent results. It is important to encourage further research to fill in these knowledge gaps and develop national or global strategies that ease the burden of VDD, especially in groups at risk.<\/jats:p>","DOI":"10.3390\/nu15204379","type":"journal-article","created":{"date-parts":[[2023,10,16]],"date-time":"2023-10-16T05:43:49Z","timestamp":1697435029000},"page":"4379","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["The Impact of Vitamin D Deficiency on Infants\u2019 Health"],"prefix":"10.3390","volume":"15","author":[{"given":"Andreea Bianca","family":"Stoica","sequence":"first","affiliation":[{"name":"Doctoral School of Medicine, George Emil Palade University of Medicine, Pharmacy, Science and Technology of T\u00e2rgu Mure\u0219, Gheorghe Marinescu Street No. 38, 540136 T\u00e2rgu Mure\u0219, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudiu","family":"M\u0103rginean","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology 2, George Emil Palade University of Medicine, Pharmacy, Science and Technology of T\u00e2rgu Mure\u0219, Gheorghe Marinescu Street No. 38, 540136 T\u00e2rgu Mure\u0219, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,16]]},"reference":[{"key":"ref_1","unstructured":"Scientific Advisory Committee on Nutrition (SACN) (2023, September 04).
