RESUMO
Objetivo: 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), ß-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.

Objective: 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), ß -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. (AU)

The aim of this study was to analyze the association between waist-to-height ratio (WHtR) and C-reactive protein (CRP) in the elderly (considering their most prevalent morbidities and lifestyles), to investigate the relationship between this anthropometric index and the presence of the most prevalent morbidities (isolated or combined), and to identify which morbidities (analyzed individually) would have greater associations with WHtR. This cross-sectional population-based epidemiological study of a stratified sampling comprised 170 elderly individuals between 60 and 90 years of age (both genders). Home visits were used to administer questionnaires and to perform anthropometric measurements and blood collection. The mean patient age was younger than 70 years, with women comprising the majority (69.41%) and with 90% of the patients presenting with inadequate WHtR. Hypertension was the most prevalent morbidity in this cohort (58.52%), and when analyzed in combination, hypertension plus obesity were the most frequently diagnosed morbidities (17.65%). Obesity, which was among the most prevalent comorbidities, was the only comorbidity combined with WHtR (p = 0.0019). Individuals with no morbidities had lower mean WHtR values compared with individuals with at least one morbidity (p = 0.0075). In the multiple linear regression model, it was identified that when individuals had one or more of the most prevalent comorbidities, the mean WHtR increased by 0.0415 (p = 0.0065). A correlation between WHtR and CRP (p = 0.0379) was also verified. Based on the relationships observed between WHtR (isolated or in combination, data unpublished) and CRP among the elderly, WHtR may represent a screening tool because it is a simple and effective anthropometric index.
