Resumo:
Vitamin D is a hormone produced naturally in the skin, and obtained through food, which
participates in several biological processes. However, the general population has a low serum
status. As this disorder being considered as pandemic, several studies have emerged showing
an association between low serum status of vitamin D and the respiratory tract diseases in
childhood. The objective of this study was to evaluate the influence of vitamin D
supplementation in children in order to prevent respiratory tract diseases. This study is an
integrative review, which consists of constructing a broad analysis of the literature, using the
PICO strategy to obtain the guiding question, and carrying out research in the Pubmed, Scopus
and BIREME databases, from 2011 to 2021, using the keywords: “vitamin D”, “respiratory
tract diseases” and “children”. Of the total of 70 articles selected, 10 articles were chosen for
the final analysis, 3 of which were developed in European countries, another 3 in countries on
the Asian continent, 2 in North America, 1 in Africa and 1 in South America, with the
corresponding period from 2011 to 2021. The results were categorized into studies that
demonstrated the correlation between the prevalence of children with hypovitaminosis D and
the presence of respiratory diseases, and how supplementation could improve or prevent
infections in children. It was seen that in groups where there was some respiratory disease, there
were a greater number of children with low serum concentrations of vitamin D. It was also seen
that supplementation could help reduce cases of recurrent respiratory infections, and improve
the clinical picture in some types of respiratory disorders. It was possible to conclude after this
study, that supplementation as a form of treatment for respiratory diseases does not have the
necessary statistical data to be recommended, however, long-term supplementation can help
reduce the appearance of respiratory diseases and mitigate relapses in children.
