Previous issue date: 2013-08-30 / One of the most important problems in the elderly is a nutritional deficiency. Several physiological changes and the use of multiple drugs interfere with appetite, food intake and absorption of nutrients, which can lead to the risk and malnutrition in the elderly, especially among institutionalized. The present study aimed to evaluate the prevalence of malnutrition and risk for malnutrition and its associated factors in institutionalized elderly. The same can be characterized by the type individual, observational and cross-sectional. Obtaining the sample was through the records of individuals of long-stay institutions for the elderly in the city of Natal, RN. The elderly were evaluated through the Mini Nutritional Assessment (MNA) and triceps skinfold (TSF) and each senior or caregiver answered a questionnaire about information like type and dietary restrictions, accessibility to food, use of alcohol and tobacco, practice physical activity and appetite. Variables such as age, gender, education, marital status, time that the elderly living in the institution, the reason for the institutionalization and comorbidities were taken from the records of each senior. The frequency of food consumption of various food groups was assessed from the questionnaire frequency of feeding study Health, Wellbeing and Aging (HWA). Data were presented as means and standard deviations, absolute and relative frequencies. To analyze the frequency of consumption, there was a factor analysis with extraction of factors from the principal components analysis with varimax rotation. A bivariate analysis was performed using the chi-square and the magnitude of the effect observed by prevalence ratio (95% CI). The Poisson regression assessed the net effect of independent variables on the two outcomes, considering a significance level of 5%. We studied twelve Homes for the Aged totaling 381 seniors eligible for the study. The prevalence of risk of malnutrition was 46.1% (45.9 to 46.2) and malnutrition was 31.4% (31.2 to 31.5). The risk of malnutrition was significantly associated with the presence of urinary incontinence (RP = 1.444, 1.113 to 1.874) was associated with malnutrition and lack of appetite (RP = 1.757, 1.246 to 2.476), the fact that the individuals do not have access to food outside the institution (RP = 0.565, 0.337 to 0.946), low water consumption (RP = 1.646, 1.101 to 2.459) and dementia (PR = 1.537, 1.072 to 2.204). The high prevalence of malnutrition and risk of malnutrition in the study suggests that we should pay attention to information
related to eating habits and the presence of comorbidities, as these can influence the nutritional status of this population / Um dos problemas mais relevantes na popula??o idosa ? a defici?ncia nutricional. V?rias altera??es fisiol?gicas e o uso de m?ltiplos medicamentos interferem no apetite, no consumo de alimentos e na absor??o dos nutrientes, podendo levar ao risco e ? desnutri??o nos idosos, especialmente entre os institucionalizados. O presente estudo objetivou avaliar a preval?ncia de desnutri??o e do risco para desnutri??o e seus fatores associados em idosos institucionalizados. O mesmo se caracterizou por ser do tipo individuado, observacional e transversal. A obten??o da amostra se deu atrav?s do cadastro de indiv?duos das institui??es de longa perman?ncia de idosos da cidade do Natal-RN. Os idosos foram avaliados atrav?s da Mini Avalia??o Nutricional (MAN) e da dobra cut?nea triciptal (DCT) e cada idoso ou cuidador respondeu a um question?rio acerca de informa??es como tipo e restri??o alimentar, acessibilidade ao alimento, uso de bebida alco?lica e tabaco, pr?tica de atividade f?sica e inapet?ncia. Vari?veis como idade, g?nero, escolaridade, estado civil, tempo que o idoso vive na institui??o, o motivo da institucionaliza??o e as comorbidades foram aferidas a partir dos prontu?rios de cada idoso. A frequ?ncia de consumo alimentar de v?rios grupos de alimentos foi aferida a partir do question?rio de frequ?ncia de consumo alimentar do estudo Sa?de, Bem estar e Envelhecimento (SABE). Os dados foram apresentados na forma de m?dias e desvios padr?o, frequ?ncias absoluta e relativa. Para an?lise da frequ?ncia de consumo, realizou-se uma an?lise fatorial com extra??o dos fatores a partir da an?lise de componentes principais com rota??o varimax. A an?lise bivariada foi realizada atrav?s do teste do qui-quadrado e verificada a magnitude do efeito atrav?s da raz?o de preval?ncia (IC 95%). A regress?o robusta de Poisson avaliou o efeito l?quido das vari?veis independentes sobre os dois desfechos, considerando um n?vel de signific?ncia de 5%. Foram estudadas 12 ILPI, totalizando 381 idosos eleg?veis para o estudo. A preval?ncia do risco de desnutri??o foi de 46,1% (45,9 - 46,2) e a de desnutri??o foi de 31,4% (31,2 - 31,5). O risco de desnutri??o esteve associado significativamente ? presen?a de incontin?ncia urin?ria (RP = 1,444; 1,113-1,874) e a desnutri??o esteve associada ? falta de apetite (RP = 1,757; 1,246-2,476), ao fato dos idosos n?o terem acesso a alimentos fora da institui??o (RP= 0,565; 0,337-0,946), ao baixo consumo de ?gua (RP = 1,646; 1,101-2,459) e ? dem?ncia (RP= 1,537; 1,072-2,204). A alta preval?ncia de desnutri??o e do risco de desnutri??o no estudo sugere que devemos nos atentar a informa??es relacionadas aos h?bitos alimentares e ? presen?a de comorbidades, pois estes podem influenciar no estado nutricional desta popula??o
