Inadequação da ingestão de Vitamina D, Cálcio e Zinco em indivíduos com câncer

Abstract

Introduction: Cancer is a multicausal disease that causes metabolic alterations and malnutrition in affected individuals. To minimize the nutritional impact of the disease and anticancer therapies, an adequate nutritional assistance to the patient's needs and adjusted in macro and micronutrients is indispensable. Objective: To estimate the prevalence of inadequate intake of vitamin D, calcium and zinc in individuals with cancer. Methods: This was an original, observational, cross-sectional prospective study, including adults and elderly with cancer, treated at a university hospital in Natal/RN, Brazil. Patient-Produced Subjective Global Self Assessment was applied and data on macro and micronutrient intake were collected through 24h recall. Chemical analysis was performed in DietSmart® software, the prevalence of micronutrient inadequacy was assessed using the Estimated Mean Requirement as cutoff point, and the Shapiro-Wilk test was used to verify the normality of the data distribution. Results: Of the 69 patients included, 56% were adults and 58% were female. The mean energy intake was 1654 Kcal, 57% carbohydrates, 20% proteins and 23% lipids. The prevalence of vitamin D inadequacy was high, with more than 50% in the total sample; calcium reached values higher than 75%; for zinc, the inadequacy was 35.94% in women and 52.39% in men. Conclusion: The evaluated population showed a high prevalence of inadequacy of the evaluated nutrients. The results obtained and their nutritional relevance suggest the importance of designing nutritional strategies to optimize the supply of these micronutrients in individuals with cancer
