Consumo de nutrientes em idosos residentes em Porto Alegre (RS), Brasil: um estudo de base populacional / Consumption of nutrients among the elderly living in Porto Alegre in the State of Rio Grande do Sul, Brazil: a population-based study

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.

Prevalência de obesidade associada à ingestão calórica, glicemia e perfil lipídico em uma amostra populacional de idosos do Sul do Brasil / Obesity prevalence associated with caloric intake, glycemia, and serum lipides in a sample population of elderly adults from Southern Brazil

OBJETIVO: Determinar a prevalência de obesidade associada ao consumo de macronutrientes, às alterações do perfil lipídico, à glicemia e à prática de atividade física em idosos. MÉTODOS: Foi realizado estudo transversal com 304 idosos do município de Porto Alegre, RS, Brasil. Medidas antropométricas de peso e altura foram utilizadas para o cálculo do índice de massa corporal (IMC) e foram analisados o perfil lipídico, a glicemia, a ingestão diária de macronutrientes e a prática de atividade física. RESULTADOS: A prevalência de obesidade foi de 30,6%, sofrendo redução com o aumento da idade. As idosas obesas apresentaram maior frequência de hipertrigliceridemia, cujos valores aumentaram conforme o aumento do IMC. Nesse grupo, a prática de atividade física foi menor. Entre os homens, houve maior consumo de proteína na dieta. CONCLUSÃO: Os resultados mostraram que a obesidade é um importante problema de saúde na Região Sul do Brasil, sofrendo influência de fatores socioculturais e econômicos que prejudicam a manutenção de uma alimentação saudável. Políticas públicas devem ser direcionadas a fim de controlar esse problema, já que a obesidade é um fator limitante para a longevidade.

OBJECTIVE: To determine the prevalence of obesity in elderly adults associated with macronutrient consumption, lipid profile, blood glucose and physical activity. METHODS: A cross-sectional-study was made with 304 elderly patients from Porto Alegre, State of Rio Grande do Sul, Brazil. Anthropometric measures of weight and height were used to calculate body mass index (BMI), and lipid profile, blood glucose, daily intake of nutrients, and physical activity were analyzed. RESULTS: The prevalence of obesity was 30.6%, decreasing with increased age. Obese women had higher frequency of hypertriglyceridemia and these values increased with increasing BMI. In this group, physical activity was lower. Among men, there was higher intake of dietary protein. CONCLUSION: The results show that obesity is an important health problem in Southern Brazil, being influenced by socio-cultural and economic factors that make it difficult to keep a healthy diet. Public policies should be adopted to control that problem, since obesity is a limiting factor for longevity.

Gender differences, polypharmacy, and potential pharmacological interactions in the elderly

OBJECTIVE: This study aims to analyze pharmacological interactions among drugs taken by elderly patients and their age and gender differences in a population from Porto Alegre, Brazil. METHODS: We retrospectively analyzed the database provided by the Institute of Geriatric and Gerontology, Porto Alegre, Brazil. The database was composed of 438 elderly and includes information about the patients' disease, therapy regimens, utilized drugs. All drugs reported by the elderly patients were classified using the Anatomical Therapeutic and Chemical Classification System. The drug-drug interactions and their severity were assessed using the Micromedex® Healthcare Series. RESULTS: Of the 438 elderly patients in the data base, 376 (85.8 percent) used pharmacotherapy, 274 were female, and 90.4 percent of females used drugs. The average number of drugs used by each individual younger than 80 years was 3.2±2.6. Women younger than 80 years old used more drugs than men in the same age group whereas men older than 80 years increased their use of drugs in relation to other age groups. Therefore, 32.6 percent of men and 49.2 percent of women described at least one interaction, and 8.1 percent of men and 10.6 percent of women described four or more potential drug-drug interactions. Two-thirds of drug-drug interactions were moderate in both genders, and most of them involved angiotensin-converting enzyme inhibitor, non-steroidal anti-inflammatory, loop and thiazide diuretics, and β-blockers. CONCLUSION: Elderly patients should be closely monitored, based on drug class, gender, age group and nutritional status.
