ABSTRACT
Resumen Objetivo: Identificar la asociación entre los factores de nutrición, actividad física, consumo de alcohol, tabaco y sueño con la sarcopenia en personas mayores. Materiales y métodos: Se realizó una búsqueda de la evidencia disponible en las bases de datos Dialnet, Science Direct, Scielo, and PubMed. Para las estrategias de búsqueda, se consideraron los términos en español e inglés, acorde a los Descriptores en Ciencias de la Salud y los Medical Subject Headings. Se emplearon los operadores booleanos "AND" y "OR". Un total de 21 estudios fueron analizados y sintetizados. Resultados: Se identificó que el consumo de nueces, frutas y omega tres puede asociarse con una menor probabilidad para desarrollar sarcopenia. El mantenerse activo sugiere una menor probabilidad para que se presente sarcopenia, en contraste las personas mayores sedentarias tienen mayores riesgos. El consumo de alcohol es un factor que se asocia con mayor probabilidad para generar sarcopenia en mujeres. En la mayoría de los estudios, el consumo de tabaco no muestra asociación significativa con la sarcopenia. En cuanto al sueño, se reporta que dormir menos de 6 horas o más de 8 horas puede incrementar la probabilidad de presentar sarcopenia en mujeres. Conclusiones: Es ideal considerar la identificación oportuna de estos factores de riesgo que están presentes en el estilo de vida, y que son susceptibles a ser modificados durante las etapas previas a la tercera edad.
Abstract Objective: To identify the association between the factors of nutrition, physical activity, alcohol consumption, tobacco and sleep with sarcopenia in older people. Materials and methods: A search of the available evidence was carried out in the Dialnet, Science Direct, Scielo, and PubMed databases. For the search strategies, the terms in Spanish and English were considered, according to the Descriptors in Health Sciences and the Medical Subject Headings. The Boolean operators "AND" and "OR" were used. A total of 21 studies were analyzed and synthesized. Results: It was identified that the consumption of nuts, fruits and omega three may be associated with a lower probability of developing sarcopenia. Staying active suggests a lower probability of sarcopenia, in contrast, sedentary older people have higher risks. Alcohol consumption is a factor that is associated with a higher probability of generating sarcopenia in women. In most studies, tobacco use shows no significant association with sarcopenia. Regarding sleep, it is reported that sleeping less than 6 hours or more tan 8 hours can increase the probability of presenting sarcopenia in women. Conclusions: It is ideal to consider the timely identification of these risk factors that are present in the lifestyle, and that are likely to be modified during the stages prior to old age.
ABSTRACT
Resumo Para descrever o perfil de consumo de nutrientes e verificar a sua associação com as variáveis sociodemográficas e de saúde, desenvolveu-se um estudo transversal, de base populacional em uma amostra aleatória de 427 idosos residentes em Porto Alegre, Brasil. O consumo alimentar foi avaliado através do Inquérito Recordatório de 24 Horas e Investigação da História Dietética. Dos idosos entrevistados, 70% eram mulheres; 48,5% possuíam entre 60 e 69 anos; 68,8% possuíam menos de 8 anos de escolaridade; 39,0%, renda familiar entre 2 e 5 salários mínimos; e 58,4% não praticava exercício físico. A hipertensão foi a doença mais prevalente, e 54,9% dos idosos estavam abaixo do peso. Os homens consumiam mais calorias, proteínas, fibras, minerais e vitaminas do que as mulheres. O consumo de carboidrato e cálcio aumentou conforme o avanço da idade, assim como diminuiu a ingestão de zinco. A prática de exercício físico elevou o consumo de calorias, magnésio, potássio e fósforo. Quanto maior a escolaridade, maior é o consumo de vitaminas B6 e B12; quanto maior a renda familiar, maior o consumo de vitamina B6 e ácido fólico. Os resultados demonstram que há deficiências nutricionais na alimentação diária da nossa população de idosos, principalmente entre as mulheres e os indivíduos acima de 80 anos.
Abstract A cross-sectional, population-based study was conducted on a random sample of 427 elderly individuals living in Porto Alegre, Brazil, to establish the nutrient consumption profile and verify its association with sociodemographic and health variables. Dietary intake was assessed using the 24-hour Food Recall Survey and the Dietetic Research Investigation technique. Seventy percent of the elderly respondents were women: 48.5% were between 60 and 69 years old; 68.8% had less than 8 years of schooling; 39% had a family income of between 2 and 5 minimum wages and 58.4% took no physical exercise. Hypertension was the most prevalent disease among the elderly and 54.9% were underweight. Men consumed more calories, protein, fiber, minerals and vitamins than women. Carbohydrate and calcium intake increases with advancing age, while zinc intake decreases. Physical exercise increased the intake of calories, magnesium, potassium and phosphorus. The higher the schooling the greater the intake of vitamins B6 and B12; the higher the family income, the greater the consumption of vitamin B6 and folic acid. The results show that there are nutritional deficiencies in the daily diet of the Brazilian elderly population, especially among women and individuals over 80 years of age.

OBJETIVO: Definir o perfil nutricional de idosos institucionalizados. M ÉTODOS: Estudo de campo comparativo correlacional e quantitativo realizado em uma Instituição de Longa Permanência, em São Paulo (SP), entre dezembro de 2010 a janeiro de 2012. Para definição do diagnóstico nutricional, coletaram-se dados de prontuários acerca de índice de massa corporal, circunferências, dobra cutânea tricipital, área muscular do braço, espessura do músculo adutor do polegar, força de preensão palmar e resultados das provas bioquímicas. As variáveis antropométricas foram apresentadas como média, desvio padrão e percentis, sendo agrupadas segundo o gênero e estratificadas por idade. O nível de significância estatística foi de p<0,05. RESULTADOS: Selecionaram-se 102 idosos, sendo 84 do gênero feminino. Excesso de peso foi o diagnóstico antropométrico que mais ocorreu nos homens (n=11; 61%) detectando-se depleção proteica a partir dos 70 anos e possíveis casos de obesidade sarcopênica. Todas as mulheres apresentaram-se eutróficas (n=84; 100%). Entretanto, em 27% (n=23) delas, evidenciou-se a depleção proteica. CONCLUSÃO: São necessários outros estudos antropométricos que permitam definir padrões de referências locais, estratificados por gênero e faixa etária. A diferença entre populações e fatores, como critérios de inclusão e exclusão e características metodológicas, limitam a utilização de padrões internacionais, interferindo na confiabilidade do diagnóstico nutricional.
OBJECTIVE: To define the nutritional profile of institutionalized elderly individuals. METHODS: Comparative correlation and quantitative field study conducted in a Long-Stay Institution in Sao Paulo (SP), Brazil, between December 2010 and January 2012. To define nutritional diagnosis, data were collected from patient files, such as body mass index, circumferences, triceps skinfold, muscle area of the arm, thickness of the adductor pollicis, handgrip strength, and biochemical test results. The anthropometric variables were presented as mean, standard deviation, and percentages, and were grouped by gender and stratified by age. The level of statistical significance was p<0.05. RESULTS: One hundred and two elderly individuals were selected, and 84 were females. Excess weight was the most common anthropometric diagnosis in men (n=11; 61%), with the detection of protein depletion in those aged 70 years, and possible cases of sarcopenic obesity. All women were in good health conditions (n=84; 100%). However, in 27% (n=23) of them, protein depletion was evident. CONCLUSION: More anthropometric studies are necessary which would allow a definition of local reference standards, stratified by gender and age group. The difference between populations and factors, such as inclusion and exclusion criteria, and methodological characteristics, limit the use of international standards, interfering in the reliability of the nutritional diagnosis.
