Methods of estimating height and weight assessment of malnutrition in patients with cancer/Metodos de estimativa de peso e altura na avaliacao de desnutricao de pacientes com cancer

To calculate the estimated and actual height and weight measures in cancer patients, evaluate the correlation and concordance of these measures and to identify the malnutrition patients. 62 cancer patients, treated at the Amaral Carvalho Hospital (Jau- SP). For classification of nutritional status, the Patient-Generated Subjective Global Assessment, the Body Mass Index and the relationship with usual weight were used. For the estimated weight was used the algorithm Chumlea et al. (7) and estimated height, the equation proposed by Chumlea et al. (8) and Kwok & Whitelaw (24). The Pearson Correlation Coefficient and the Intraclass Correlation Coefficient was calculated and simple linear regression was conducted. To compare the malnutrition detected by different methods, the Cochran's Q test were performed. There was a strong and significant correlation between the estimated and actual weight (r=0,95; CI95%=0,92-0,97; p
