Frequency and Determinants of Vitamin A Deficiency in Children Under 5 Years of Age with Pneumonia
Vitamin A deficiency (VAD) has been closely related to acute respiratory infections (ARI), although information is still incomplete; for example, the frequency of VAD in children

This study was conducted to gain insight into the status of vitamin A in children with pneumonia. A secondary objective was to identify the sociodemographic, individual, and nutritional factors associated with VAD in these children.
A cross-sectional study was conducted in the Mexican state of Hidalgo, one of the poorest in the country. Children with community-acquired pneumonia treated at nine public hospitals were included. Information was obtained by interviewing mothers, and ascertainment of vitamin A status was performed with relative-dose-response (RDR) test.
A total of 422 cases were included. VAD was identified in 17.8% of children; 50.3% showed normal results, 24.6% had liver reserve depletion, and 7.3% showed results attributable to the infectious process. Variables associated with VAD were as follows: age <2 months (OR 3.44, 95% CI: 1.84–9.24); children >6 months of age fed with formula (OR 0.37, 95% CI: 0.15–0.91), and affiliation with the Mexican Social Security Institute (IMSS) health system (OR 0.40, 95% CI: 0.22–0.72).
The frequency of VAD in children with community-acquired pneumonia confirms that the problem of deficiency persists in Mexico. The associated factors for VAD found in this study can be taken into account when planning and evaluating vitamin A supplementation activities in populations with high risk for deficiency.</description><identifier>ISSN: 0188-4409</identifier><identifier>EISSN: 1873-5487</identifier><identifier>DOI: 10.1016/S0188-4409(01)00361-7</identifier><identifier>PMID: 11886719</identifier><language>eng</language><publisher>United States: Elsevier Inc</publisher><subject>Child, Preschool ; Children ; Cross-Sectional Studies ; Female ; Humans ; Infant ; Liver - metabolism ; Male ; Mexico ; Pneumonia ; Pneumonia - complications ; Relative-dose-response test ; Risk factors ; Vitamin A - administration & dosage ; Vitamin A - blood ; Vitamin A deficiency ; Vitamin A Deficiency - complications ; Vitamin A Deficiency - epidemiology</subject><ispartof>Archives of medical research, 2002-03, Vol.33 (2), p.180-185</ispartof><rights>2002</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c413t-f85f75b61ac4336684654197364700618b530b2e8ab1d681673328f62d4e57153</citedby><cites>FETCH-LOGICAL-c413t-f85f75b61ac4336684654197364700618b530b2e8ab1d681673328f62d4e57153</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktohtml>$$Uhttps://www.sciencedirect.com/science/article/pii/S0188440901003617$$EHTML$$P50$$Gelsevier$$H</linktohtml><link.rule.ids>314,776,780,3537,27901,27902,65306</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/11886719$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Reyes, Hortensia</creatorcontrib><creatorcontrib>Villalpando, Salvador</creatorcontrib><creatorcontrib>Pérez-Cuevas, Ricardo</creatorcontrib><creatorcontrib>Rodrı́guez, Leticia</creatorcontrib><creatorcontrib>Pérez-Cuevas, Miriam</creatorcontrib><creatorcontrib>Montalvo, Irene</creatorcontrib><creatorcontrib>Guiscafré, Héctor</creatorcontrib><title>Frequency and Determinants of Vitamin A Deficiency in Children Under 5 Years of Age with Pneumonia</title><title>Archives of medical research</title><addtitle>Arch Med Res</addtitle><description>Vitamin A deficiency (VAD) has been closely related to acute respiratory infections (ARI), although information is still incomplete; for example, the frequency of VAD in children <5 years of age with pneumonia is not known, and the conditions associated with VAD have not been identified.
