IntroductionThe incidence of cancer is increasing worldwide and with it the prevalence of malnutrition, which is responsible for the death of almost 20 % of cancer patients. The objective of this study was to identify the factors associated with malnutrition in hospitalized cancer patients.MethodsCross-sectional study conducted with 277 hospitalized patients in the Institute of Integrative Medicine Prof. Fernando Figueira from March to November 2013. The nutritional status was classified as well-nourished and moderate/severe malnutrition, according to the Patient-Generated Subjective Global Assessment. The association between moderate/severe malnutrition and demographic, behavioral, socioeconomic, clinical, therapeutic and nutritional variables was investigated through univariate regression and hierarchical Poisson models, with a 5 % significance level.ResultsThe prevalence of malnutrition was 71.1 %, being classified as moderate in 35.4 % and severe in 35.7 %. After multivariate analysis, smokers/ex-smokers low socioeconomic status, performance status ≥2 and age ≥60 years were associated with increased risk of malnutrition.ConclusionThere was observed a high prevalence of moderate/severe malnutrition in cancer patients, with the increased risk of malnutrition associated with the presence of factors that can be assessed during hospital admission suggesting a higher alert of the medical and health care staff about the need for nutritional assessment and intervention.

Chronic non-communicable diseases have been the cause of more than half of deaths in the world, and, among many other diseases, obesity. One of the factors for the increase in obesity is unhealthy eating habits, and this study aimed to present an educational diagnosis of the difficulties found by workers at Pediatric Hospital of Federal University of Rio Grande do Norte to incorporate healthy eating habits in their daily lives. Feeding involves cultural, social, emotional and sensory aspects, making people feed seeking not only nutrients but also the significance of the chosen food. Thus, a food and nutrition education intervention should include these aspects and be preceded by educational diagnosis, to surround the question of intrinsic human subjectivity to eat. To trace this educational diagnosis, focus group sessions were addressed, with 14 research subjects, to obtain data on the basis of discussion focused on a specific theme. The results can be to list five categories of problems: "no time", "entrenched eating habits," "lack of access to healthy lifestyles", "tasty is unhealthy" and "diet is sacrifice." Therefore, nutritional food education strategies must take place focused on self-care, and adequate food as an expression of citizenship. Furthermore, it is suggested that healthy eating practices are encouraged and promoted in the workplace.
