RESUMOObjetivo: Avaliar a relação entre os valores de leucócitos e proteína C-reativa ultrassensível (PCR-us) e o consumo alimentar habitual de vitaminas com ação antioxidante em idosos, considerando-se a inexistência de estudos. Material e Métodos: Adotou-se delineamento epidemiológico transversal, utilizando-se amostragem de uma população idosa, envolvendo 174 indivíduos com idade igual ou superior a 60 anos, de diferentes condições socioeconômicas e de saúde, como obesidade, hipertensão e diabetes. Resultados: Para verificar a correlação entre as variáveis, utilizou-se o coeficiente de correlação de Spearman. Houve correlação negativa entre os valores de leucócito e vitamina E (r = -0,29, p = 0,0316), β-caroteno (r = -0,32, p = 0,0189), leucócito e vitamina A (r = -0,36, p= 0,0062), e correlação entre os valores de leucócito e vitamina C, como também entre PCR-us e o consumo alimentar habitual dessas vitaminas. Conclusão: Com base nas correlações encontradas entre os valores de leucócitos e as vitaminas mencionadas, a ingestão dessas vitaminas, seria ainda mais justificada, considerando-se também, a sua importância na adequação dos valores de leucócitos. DESCRITORES Idoso. Leucócitos. Proteína C-reativa. Ingestão alimentar. ABSTRACTObjective: To evaluate the relationship between leukocyte counts and ultra-sensitive C-reactive protein (hs-CRP) and the usual dietary intake of vitamins with antioxidant action in the elderly. Material and Methods: This was a cross-sectional epidemiological study with a sample of 174 individuals aged 60 years and over, from different socioeconomic and health conditions, such as obesity, hypertension and diabetes. Results: To verify the correlation among the study variables, the Spearman correlation coefficient was utilized. There was a negative correlation between leukocyte counts and the intake of vitamin E (r = -0.29, p = 0.0316), β -carotene (r = -0.32, p = 0.0189), as well as vitamin A (r = -0.36, p = 0.0062). On the other hand, there was a correlation between leukocyte counts and the intake of vitamin C as well as between the hs-CRP and the usual intake of these vitamins. Conclusion: Based on the correlations found, the intake of these vitamins would be more justified considering their importance in the adaptability of leukocyte counts.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
