Summary: | Objective To investigate risk factors associated with hypovitaminosis D in adult patients infected with HIV/aids, at a referral hospital in Maceió, Brazil. Subjects and methods This cross-sectional study involved 125 patients evaluated from April to September 2013 by means of interviews, review of medical records, physical examination, and laboratory tests. The data were analyzed using the SPSS® software, version 17.0; the prevalence of hypovitaminosis D and mean levels of vitamin D were determined. The association between hypovitaminosis D and the independent variables was assessed using the Chi-square or the Fisher’s exact tests; mean vitamin D concentrations were analyzed using Kolmogorov-Smirnov, Mann-Whitney, and Kruskal-Wallis tests. The level of significance was set at 5% across tests. Results The prevalence of hypovitaminosis D was 24%, with a significant association with higher household income (p < 0.05). Higher vitamin D levels were associated with female gender (p < 0.001), no use of sunscreen (p < 0.05), and previous opportunistic infections (p < 0.01). Lower values were associated with the use of antiretroviral medication (p < 0.05), overweight and obesity (p < 0.01). Conclusion Lower vitamin D concentrations were significantly associated with well-known risk factors for hypovitaminosis D: use of sunscreen, antiretroviral medication, overweight, and obesity. The prevalence of hypovitaminosis D in this study, considering values > 20 ng/mL or > 30 ng/mL as vitamin D sufficiency, was lower to that of previous studies with HIV-infected patients, a fact that might be related to the low latitude and high intensity of solar radiation of the location of the present study.
Objetivo Investigar fatores de risco associados à hipovitaminose D em pacientes adultos infectados por HIV/aids, num centro de referência em Maceió-AL. Sujeitos e métodos Por meio de desenho transversal, 125 pacientes foram avaliados por entrevista, revisão de prontuário, exame físico e laboratorial, no período de abril a setembro de 2013. Os dados foram analisados por meio do software SPSS®, versão 17.0, sendo determinados a prevalência de hipovitaminose D e os níveis médios de vitamina D. Para avaliação da associação entre hipovitaminose D e as variáveis pesquisadas, foram utilizados o teste Qui-quadrado ou o teste exato de Fisher, enquanto para os níveis médios de vitamina D foram utilizados os testes Kolmogorov-Smirnov, Mann-Whitney e Kruskal-Wallis. O nível de significância foi |
