Abstract
OBJETIVO: Fornecer dados antropométricos de idosos residentes na área urbana do município de Joinville, SC. Metodologia: Foram analisados 218 idosos com idade igual ou superior a 60 anos, de ambos os sexos, não institucionalizados e residentes na área urbana da cidade de Joinville-SC, no ano de 2002. Os idosos foram apresentados segundo sexo e grupo etário: 60-69 anos, 70-79 anos e 80 e mais. As variáveis antropométricas foram apresentadas sob a forma de média, desvio-padrão e percentil (P5, P10, P25, P50, P75, P90 e P95). RESULTADOS: Dos 218 idosos, 130 (59,6%) foram mulheres e 88 (40,4%) homens. Apesar de os valores médios da maioria das variáveis investigadas sugerirem uma tendência a diminuir com o aumento da idade, não houve diferença estatisticamente significativa dos valores médios entre os grupos etários para ambos os sexos (p>0,05). Quando comparados por sexo, os valores médios de IMC, CQ e DCT das mulheres foram significativamente superiores aos dos homens. Estes, em contrapartida, apresentaram valor médio da CC significativamente superior ao das mulheres (p<0,05). CONCLUSÃO: A maioria dos estudos realizados com idosos em outros países tem investigado esta categoria considerando pessoas com idade igual ou superior a 65 anos, o que dificulta a comparação com os dados brasileiros. Somado a outros estudos realizados com idosos no Brasil, os dados obtidos neste estudo podem contribuir para a construção de um padrão antropométrico da população idosa brasileira, ainda inexistente no país.

Abstract
OBJECTIVE The objective of this study was to identify the nutritional status of hospitalized elderly and verify if calf circumference can be a tool to monitor nutritional status in this population. METHODS A total of 170 inpatients (79 men and 91 women) aged more than 60 years were assessed. Anthropometric and dietary assessments were done according to standard procedures. The software STATISTICA 6.0 was used for the statistical analysis. The confidence interval was set at 95% and significance level at 5% (p < 0.05). RESULTS Body mass index assessment revealed a high rate of underweight patients (45.3%), and arm circumference and triceps skinfold revealed a high prevalence of depletion. Males had more lean mass according to the mid-arm muscle circumference (p=0.017) and mid-arm muscle area (p=0.01), and females presented higher triceps skinfold values (p < 0.001). There was a positive correlation between calf circumference and Body Mass Index (p < 0.001), arm circumference (p=0.001), triceps skinfold (p=0.001), mid-arm muscle circumference (p=0.001), and mid-arm muscle area (p=0.001). CONCLUSION This study found a positive correlation between calf circumference and nutritional status of assessed patients indicating that this measurement can be used as a complementary tool for monitoring the nutritional status of elderly inpatients.

Abstract
OBJECTIVE Determine basic anthropometry for elderly participants in a Venezuelan community and compare results for subgroups with different health status. METHOD Standardized anthropometric, nutritional, neurological, neuropsychiatric, and cardiovascular assessments generated data on weight, height, and body mass index (BMI) by sex and age for the total sample, for normative groups without health problems that might impact anthropometry, and for reference groups with no major health problems. Centile curves of anthropometric measurements versus age are determined for women and men in the normative group. RESULTS Mean weight and height are significantly different between sexes, but not BMI. All three parameters show gradual declines with age. The mean 90% central interval for BMI in the normative and reference groups is 20-29 kg/m(2). CONCLUSION The anthropometric data for healthy elderly Venezuelans can be used in monitoring anthropometric changes and disease risk analysis for this population and possibly for other Latin American populations.

Abstract
The aim of this study was to estimate obesity prevalence and associated factors in the elderly, according to two cutoff points for body mass index (BMI). This was a cross-sectional, population-based study of a sample of 596 elderly residents in Pelotas, southern Brazil. Nutritional status was evaluated through BMI based on self-reported weight and stature. Poisson multiple regression with hierarchical analysis was applied, with two dependent variables for definition of obesity: BMI > 27 kg/m(2) and BMI > or =30 kg/m(2), the cutoff points proposed by Lipschitz and the World Health Organization, respectively. Prevalence of obesity was 48.7% (95%CI: 44.6-52.7) for BMI > 27 kg/m2 and 25.3% (95%CI: 21.9-29.0) for BMI > or =30 kg/m(2). Two multiple regression models showed an association between obesity and female gender and age. BMI > 27 kg/m(2) showed an association with age and smoking and BMI > or =30 kg/m(2) with sedentary lifestyle. Obesity prevalence was high in this group of elderly. For the Brazilian elderly population and from a public health perspective, the study suggests the use of a more sensitive cutoff point, namely BMI > 27 kg/m(2).

Abstract
OBJECTIVES The aim of this study was to evaluate sex- and age-related variations of the nutritional status in the aged population of central Sardinia, a geographical area with a high frequency of long-lived people, particularly men. DESIGN The sample consisted of 200 subjects over 70 years of age (men: N= 100, age= 81.0 +/- 7.0 years; women: N= 100, age= 81.5 +/- 7.3 years). SETTING Orroli (central Sardinia, Italy). MEASUREMENTS Mini nutritional assessment (MNA) and bioelectrical impedance vector analysis (BIVA) were used to evaluate nutritional status and body composition. RESULTS The indicators revealed a generally good nutritional status. The MNA results (men: 24.6 +/- 2.2; women: 23.4 +/- 2.5) showed that 64.1% of the subjects had a normal nutritional status and only a small proportion (1.2%) could be classified as malnourished. BIVA showed that most subjects (74.2%) were normal, while the prevalence of low body cell mass was 10.7% and that of dehydration 11.2%. According to the MNA, the nutritional status was significantly better in the men. Almost three-quarters of the men (73.1%) were well nourished vs. half of the women (50.6%). A worsening of the nutritional status with age was observed. The proportion of malnourished individuals, as assessed by MNA, increased from 0% to 9.1% from 70-79 to > 90 years. CONCLUSIONS With respect to their contemporaries from other regions, the elderly of Orroli presented a better nutritional status, a similar worsening with age and generally higher sexual dimorphism.

Abstract
Chronic health problems may be related to body mass index (BMI, kg/m(2)), but this has been best documented in overweight and obese adults. The primary objective of this study was to identify factors associated with different categories of BMI in elderly men and women from the general population, also including the lower categories of BMI. In a cross-sectional population survey from the municipality of Tromsø, Norway we analyzed associations between BMI and a wide range of chronic disease conditions, lifestyle and socioeconomic factors. BMI was categorized into six groups (<20, 20.0-22.4, 22.5-24.9, 25.0-27.4, 27.5-29.9, > or =30.0 kg/m(2)). The study included 4,259 men and women aged 65 years and older from the general population. We found low relative weight (BMI < 20 kg/m(2)) to be associated with increasing prevalence of mental distress, hip fracture, smoking and low handgrip strength. A U-shaped relation to BMI was found for asthma and chronic bronchitis, poor current health and low physical activity. The higher categories of BMI were associated with low education level, a difficult economical situation, diabetes mellitus and ischemic heart disease. These results demonstrate that both low and high BMI are associated with a wide range of prevalent conditions and diseases in elderly men and women. For the clinician the findings emphasize the importance of nutritional assessment as part of the medical evaluation of elderly patients.

Abstract
We investigated the relationship of metabolic syndrome (MetS) and its individual components with incidence of mild cognitive impairment (MCI) and its progression to dementia in a large longitudinal Italian population-based sample with a 3.5-year follow-up. A total of 2097 participants from a sample of 5632 65-84-year-old subjects from the Italian Longitudinal Study on Aging were evaluated. MetS was defined according to the Third Adults Treatment Panel of the National Cholesterol Education Program criteria. MCI, dementia, Alzheimer's disease (AD), and vascular dementia (VaD) were classified using current published criteria. Among MCI patients those with MetS (N=49) had a higher risk of progression to dementia (HR, 4.40; 95% CI, 1.30-14.82) compared with those without MetS (N=72). After a multivariate adjustment, the risk in MCI patients with MetS approximately doubled (multivariate adjusted HR, 7.80, 95% CI 1.29-47.20) compared with those MCI without MetS. Finally, among non-cognitively impaired individuals there were no significant differences in risks of developing MCI in those who were affected by MetS (N=608) in comparison with those without MetS (N=837), as well as excluding those individuals with undernutrition or low inflammatory status with or without undernutrition. In our population, among MCI patients the presence of MetS independently predicted an increased risk of progression to dementia over 3.5 years of follow-up.

Abstract
OBJETIVO: Avaliar o risco nutricional de idosos institucionalizados por diferentes instrumentos de avaliação nutricional. MÉTODOS: Estudo transversal com 37 idosos (60 a 100 anos) residentes em Instituição de Longa Permanência do Distrito Federal. A avaliação incluiu diferentes critérios antropométricos: índice de massa corporal, circunferência do braço, da panturrilha, da intura, razão cintura/quadril, perda e ganho ponderal, contagem total de linfócitos e a aplicação da Mini Avaliação Nutricional. RESULTADOS: As proporções de 36,1% de desnutridos, 16,7% de sobrepeso + obesidade e 47,2% de eutróficos foram verificadas, quando a medida de circunferência do braço foi o instrumento utilizado. A avaliação realizada com o índice de massa corporal mostrou a presença de 47,9% de eutrofia, menor proporção de baixo peso (27,0%) e de sobrepeso (27,0%). O risco para doenças cardiovasculares, segundo a circunferência da cintura, foi estimado em 86,4% das mulheres e 57,1% dos homens. Contudo, quando este mesmo risco foi julgado utilizando-se a razão entre a circunferência da cintura e a circunferência do quadril, a proporção de 95,5% foi significantemente maior no grupo de mulheres (42,9%, masculino). A depleção imunológica foi constatada em 46,7% dos homens e 66,7% das mulheres. O estado nutricional, classificado pela Mini Avaliação Nutricional, apontou 50,0% de mulheres e 40,0% de homens com risco de desnutrição. O risco nutricional foi observado em 83,8% dos idosos quando considerada, como critério para este diagnóstico, a presença de pelo menos um dos índices antropométricos abaixo da normalidade. Resultado semelhante, de 75,7% de risco, foi obtido com a Mini Avaliação Nutricional. CONCLUSÃO: Na instituição sob estudo uma maioria significativa de idosos, independentemente do sexo, apresentou risco nutricional, a julgar pelos indicadores antropométricos utilizados ou pela Mini Avaliação Nutricional.

Abstract
AbstractObjectivesTo evaluate the prevalence of undernutrition among community-dwelling elderly people in Spain using the Mini Nutritional Assessment (MNA) and to analyse its distribution according to age, gender and residence region.DesignCross-sectional study assessing the nutritional status of elderly persons through both the short form and the full version of the MNA test.SettingPharmacy offices across the whole country (Spain) were enrolled to recruit participants.SubjectsA total of 22 007 participants (8014 men and 13 993 women), aged ≥65 years, assessed during the last two months of 2005.ResultsAccording to MNA screening, 4·3 % subjects were classified as undernourished (MNA score <17) and 25·4 % were at risk of undernutrition (MNA score ≥17 to ≤23·5). The MNA short form correlated strongly with the full MNA version (r = 0·85). MNA total score was significantly higher in men than in women (25·4 (sd 3·7) v. 24·6 (sd 3·9); P < 0·001) and lower in the oldest than in the youngest subjects (P < 0·001) in both genders. According to regional distribution, the best nutritional status was found in elderly from the north of Spain excluding the north-west area.ConclusionsFemale gender, older age and living in the south half or north-west of the country were associated with higher rates of undernutrition among community-dwelling elderly persons in Spain.

Abstract
OBJETIVOS: Investigar a associação entre o grau de risco de disfagia e o risco nutricional dos pacientes idosos internados na clínica médica do Hospital Universitário de Brasília. MÉTODOS: Estudo transversal, analítico, original, observacional, não-controlado, com amostra de conveniência e estratificada. Foram aplicados a Mini Avaliação Nutricional e o questionário de risco de disfagia em 49 pacientes idosos nas primeiras 48 horas após admissão na clínica médica, em setembro de 2006. RESULTADOS: A freqüência de idosos foi maior na faixa etária entre 60-74 anos 11meses (78%), com média de idade de 69 anos, sendo 41% mulheres e 59% homens. A proporção de risco de disfagia dos pacientes idosos foi de 69% e do estado nutricional inadequado de 71%, valor elevado principalmente entre as mulheres. Ambos os sexos se encontram em risco nutricional, masculino (20,5, Desvio-padrão - DP=5) e feminino (19, DP=6). O estudo mostrou que as mulheres apresentam uma tendência maior para risco de disfagia, porém os homens apresentam um quadro de maior gravidade (risco moderado). Foi encontrada uma correlação negativa moderada entre os valores de risco de disfagia e seus respectivos scores da Mini Avaliação Nutricional. CONCLUSÃO: Foi verificado neste estudo que os idosos apresentam dois agravantes de sua qualidade de vida: estado nutricional e disfagia, que podem ser agudizados na internação hospitalar.

Abstract
The objective of this study was to provide data on malnutrition prevalence in hospitals, nursing homes and home-care organisations in The Netherlands in a nationally representative sample, and to assess the factors such as age, sex, time since admission, ward type and disease for identifying patients at high risk of malnutrition. A cross-sectional, multi-centre design with a standardised questionnaire was used to measure the prevalence of malnutrition. Nutritional status was assessed by BMI, undesired weight loss and nutritional intake. In this study, 12 883 patients were included. The prevalence of malnutrition was the highest in hospitals (23·8 %), followed by home-care organisations (21·7 %) and nursing homes (19·2 %). Logistic regression analysis revealed no association with age, time since admission and ward type. Being female was associated with malnutrition only in nursing homes. Blood diseases, gastrointestinal tract diseases, infection, chronic obstructive pulmonary disease, dementia and cancer were the factors associated with malnutrition in hospitals. Dementia was associated with malnutrition in nursing homes, while gastrointestinal tract diseases, diabetes mellitus and cancer were the associated factors in home care. This study shows that malnutrition is still a substantial problem in hospitals, nursing homes and home care in The Netherlands. Malnutrition is a problem for more than one in five patients. Despite growing attention to the problem, more continued alertness is required.

Abstract
OBJETIVO: O aumento da população idosa em países desenvolvidos, como naqueles em desenvolvimento, desperta interesse e preocupação com o planejamento de políticas públicas voltadas para a atenção nutricional do idoso. O objetivo desta pesquisa foi descrever o perfil nutricional de idosos voluntários pertencentes a grupos paroquiais, para propor o monitoramento da situação nutricional da população idosa no município de Pinhais, na Região Metropolitana de Curitiba (PR). MÉTODOS: A população incluída na pesquisa foi de 209 idosos voluntários, pertencentes aos grupos paroquiais de adultos e idosos do município. O diagnóstico do estado nutricional dos idosos foi realizado por meio de medidas antropométricas, com o cálculo do Índice de Massa Corporal, utilizando como critérios diagnósticos os pontos de corte recomendados pelo Ministério da Saúde. Dados sócio-demográficos, como grupo etário, sexo, grau de escolaridade, morbidades, tipo de serviço de saúde utilizado pela população idosa, também foram coletados no período de agosto a novembro de 2003. O Programa Epi Info, versão 6.04, foi utilizado para as análises estatísticas. RESULTADOS: Os resultados encontrados mostraram a ocorrência de importantes prevalências de inadequação do estado nutricional na população idosa do Município de Pinhais, onde 57,4% dos idosos apresentaram sobrepeso e 9,6% baixo peso. Os resultados indicam a necessidade de criar um instrumento de monitoramento da situação nutricional para a população idosa do município, sugerindo o Sistema de Vigilância Alimentar e Nutricional para este grupo etário.

Abstract
OBJETIVO: Identificar o estado nutricional, segundo o índice de massa corporal, e fornecer informações sobre medidas antropométricas de idosos institucionalizados no município de Florianópolis (SC). MÉTODOS: Estudo transversal, no qual a população em estudo foi composta por 232 idosos, com idade a partir de 60 anos, residentes em instituições geriátricas do município de Florianópolis (SC). A avaliação antropométrica foi realizada obtendo-se o valor do índice de massa corporal, da prega cutânea triciptal e da circunferência da panturrilha. O diagnóstico do estado nutricional foi realizado utilizando-se os pontos de corte preconizados pela Organização Pan-Americana de Saúde para índice de massa corporal. Os dados são apresentados sob a forma de média e desvio-padrão. Foi realizado o teste t de Student para verificar a diferença entre os valores médios das variáveis entre os sexos. RESULTADOS: A amostra constituiu-se de 167 idosos de ambos os sexos. Encontrou-se uma prevalência de 45,5% de baixo peso, 33,5% de peso normal, 7,8% de pré-obesidade e 13,2% de obesidade. Para todas as variáveis antropométricas, o valor médio das mulheres foi superior ao dos homens. CONCLUSÃO: Os resultados encontrados indicaram a prevalência de 66,5% da amostra com estado nutricional inadequado, evidenciando a necessidade de medidas de promoção ou reabilitação da saúde dos idosos. Os dados mostram que há diferenças entre os sexos com relação ao estado nutricional e às variáveis índice de massa corporal e prega cutânea triciptal, além de contribuírem para a ampliação do referencial antropométrico de idosos institucionalizados.

Abstract
OBJECTIVES to examine differences between measured height and demi-span equivalent height (DEH) among people aged >or=65 and investigate the impact on body mass index (BMI) of using DEH. DESIGN AND SETTING nationally representative cross-sectional sample of adults living in England. PARTICIPANTS 3,346 non-institutionalised adults aged >or=65, taking part in the Health Survey for England (HSE) 2001. MEASUREMENTS height, weight and demi-span measurements were taken according to standardised HSE protocols. DEH was calculated using Bassey's equation. RESULTS the height measurement was lower than the DEH from age group 70-74 years onwards in men and in each age group in women. No significant differences in mean DEH and measured height were found for men (-0.46) or women (-2.64). BMI derived from measured height did not differ significantly from BMI derived from DEH. The prevalence of underweight was lower when using measured height than when using DEH in women aged >or=65, particularly in those aged 80 years and over. The prevalence of overweight and obesity was higher using measured height than DEH in women aged >or=65. CONCLUSION we confirmed in a large nationally representative sample that demi-span measurement may be a useful estimate of stature in people (particularly women) aged >or=65 for BMI calculations.

Abstract
The metabolic syndrome (MetS) is represented by the co-occurrence of multiple metabolic and physiologic risk factors for both type 2 diabetes mellitus and atherosclerotic cardiovascular diseases. In spite of its high frequency and association with morbidity and mortality in the adult population, very little is known about its magnitude in the elderly and about the validity of the diagnostic criteria commonly used. The objective of this paper is to assess the prevalence rate of MetS and the validity of the Adult Treatment Panel III (ATP III) diagnostic criteria in an elderly Caucasian cohort, considering data from the Italian Longitudinal Study on Aging (ILSA), a population-based study with a sample of 5632 individuals aged 65-84 years at baseline (1992). Logistic regression models and ROC curve were used to test the validity of the cut off levels proposed. The prevalence of MetS was 31.5% in men, and 59.8% in women. The cut off levels suggested for both men and women by the ATP III panel indicated a significant association with the MetS for all components. Actually, the ROC analysis would suggest lower levels for glycaemia (106 mg/dl) in men, and higher levels for blood pressure in both men and women (145/95 and 135/90, respectively). Concluding, MetS is very common in the aged Caucasians and the diagnostic criteria proposed by the ATP III panel seem to be appropriate in older individuals. Small adjustments in the cut off levels could be suggested for glycaemia (men) and in blood pressure (men and women).

Abstract
O objetivo deste estudo foi descrever as variáveis indicadoras de gordura e massa muscular dos idosos de Fortaleza, Ceará, Brasil. Este estudo é populacional, transversal, domiciliar, realizado com idosos (60 anos ou mais) residentes em Fortaleza. As variáveis verificadas foram: dobra cutânea tricipital (DCT), área de gordura do braço (AGB), perímetro do braço (PB), circunferência muscular do braço (CMB), área muscular do braço (AMB) e área muscular do braço corrigida (AMBc). Foram avaliados 483 idosos. O valor médio da DCT das mulheres foi significativamente superior ao dos homens (p < 0,05), assim como o valor médio da AGB (p < 0,05). As variáveis CMB, AMB e AMBc apresentaram valor médio maior entre os homens, quando comparados às mulheres (p < 0,05). Em todas as variáveis houve diminuição dos valores médios e percentil com o avançar dos grupos etários, com exceção do percentil da DCT para as mulheres. O padrão antropométrico e de composição corporal dos idosos deste trabalho segue a tendência de outros estudos, no entanto, os valores diferem. Com isso, sugere-se que as informações deste estudo sejam utilizadas como padrão de referência para idosos de Fortaleza.

Abstract
Adipose tissue is considered an efficient system in which to store energy. Throughout life, the total amount of body fat exhibits some oscillations. Typically, there are three specific periods in which there are notable increases in fat mass, specifically early in life, during pregnancy and lactation, and with ageing. The existence of the first two peaks in fat mass has been interpreted, from an evolutionary point of view, as a beneficial manoeuvre to protect against the scarcity of energy to the offspring of the species. Nevertheless, the role of increasing body fat with ageing is more dubious. However, recent evidence suggests that the gain in adiposity in senescence may also be interpreted in the same evolutionary context. The aim of this review is to focus on the age-related changes in fat depots. In addition, an evolutionary explanation to the observed changes has been emphasized.

Abstract
As the elderly population is increasing rapidly, there is a lot of scientific interest in clarifying the differential life-style, genetic, biochemical and molecular factors contributing to mortality or exceptional longevity. Within the framework of the ZINCAGE project, 249 old (60-85 years) and nonagenarian Greek subjects (>/=85 years old) were recruited and anthropometrical, blood and biochemical indices as well as blood pressure measurements were obtained. Based upon the inclusion criteria, 214 of them were characterized as healthy (136 female, 78 male), while those characterized as non-healthy were excluded from the statistical analysis. The findings indicated an 88.4% prevalence of overweight and obesity in elderly (91.2% in women, 83.3% in men), while a significant decrease in body mass index with age was recorded. Hypercholesterolemia was observed in 75.3% of elderly women and in 69.2% of men. Erythrocyte sedimentation rate value was increased in 27.6% of all healthy elderly, while zinc deficiency was observed in 18.7% of elderly. Over 85.0% of all healthy elderly were within normal range for all other hematological analysis. Blood analysis confirmed the good health status of the elderly recruited as healthy, except for the high prevalence of obesity and hypercholesterolemia.

Abstract
OBJETIVO: Comparar as medidas antropométricas da envergadura e circunferência braquial para avaliação do estado nutricional de idosos em relação ao Índice de Massa Corporal. MÉTODOS: Foram estudados 308 idosos residentes em instituições asilares públicas e particulares em Pernambuco, Brasil. RESULTADOS: A sensibilidade do Índice de Massa Corporal, tendo a envergadura como preditora da estatura, no diagnóstico da desnutrição, foi de 93,5%, com especificidade de 82,0%. Com relação ao diagnóstico de sobrepeso e obesidade, o cálculo do Índice de Massa Corporal, utilizando a envergadura, demonstrou sensibilidade de 44,5% e 83,3% e especificidade de 87,0% e 100,0%, respectivamente. A circunferência braquial apresentou, no diagnóstico de desnutrição, sensibilidade e especificidade de 89,0% e 87,0%, respectivamente. CONCLUSÃO: Em idosos, o uso da envergadura em substituição à altura no cálculo do Índice de Massa Corporal, mostrou-se um bom indicador no diagnóstico de desnutrição e de obesidade, no entanto não se observou o mesmo em relação ao diagnóstico de sobrepeso. A medida da circunferência braquial foi também um bom indicador para determinar desnutrição em idosos.

Abstract
Until now, determining the sex of a recently deceased individual using the measurement of the bicondylar breadth of the femur (also known as condylar width, epicondylar breadth and distal epiphyseal breadth) raised some concerns as to accuracy because no sample of contemporary French subjects was available. In this study, a sample of 88 female and male femurs taken from recently deceased elderly French people was studied. The bones were collected from subjects who had donated their bodies to the Medical School of Nice. The mean value of the male bicondylar breadth was found to be greater than that of females (84.3mm versus 74.8mm), confirming the sexual dimorphism of this parameter. Furthermore, the results showed a 95.4% accuracy rate for sexing individuals. To date, in the French population, as in some other samples, epicondylar breadth is the single most accurate measurement of sex determination, ahead even of head diameter. A discriminant function is presented to allow sex determination from remains of the distal femur. With regard to the data available in the literature, sexual dimorphism is probably the result of both genetic and environmental factors. The comparison of our results with those of other populations shows that there are inter-population variations of the bicondylar breadth, and also intra-population variations that account for the differences in the accuracy rate of this variable for the purposes of sex determination. These findings underscore the need to re-evaluate bone measurements within various contemporary populations.

Abstract
BACKGROUND Body mass index (BMI) is often used to reflect total body fat amount (general obesity), whereas waist circumference (WC), waist-to-hip ratio (WHpR) or waist-to height ratio (WHtR) is used as a surrogate of body fat centralization (central obesity). The purpose of the present study was to identify cut-offs for BMI and upper-body adiposity (WC, WHpR, and WHtR) that, associated with increased risk of type 2 DM and hypertension in Iraqi adults, would be consistent with overweight and central adiposity. METHODS This was a community-based cross-sectional survey for establishing cut-off values for BMI and upper-body adiposity (WC, WHpR or WHtR) associated with increased risk of type 2 DM and hypertension from one district in Southern Iraq, Basrah (Abu-Al-khasib). The total number of persons involved was 12,986 (6693 men and 6293 women), aged 45.6 +/- 15.7 years. RESULTS The cut-off point in men associated with increased risk of type 2 DM and hypertension were BMI 25.4 and 24.9, WC 90 and 95 cm, WHpR 0.92 for both and WHtR 0.52 and 0.55, respectively. For women, the cut-off point associated with increased risk of type 2 DM and hypertension were BMI 26.1 and 26.5, WC 91 and 95 cm, WHpR 0.91 for both, and for WHtR 0.56 and 0.59, respectively. The best index for association with type 2 DM was WHpR with cut-off point of 0.92 for men and 0.91 for women. For hypertension, the best index is WHtR (with cut-off point of 0.55 for men and 0.59 for women), whereas the least reliable index was the BMI for both type 2 DM and hypertension. CONCLUSIONS Our finding showed that, in Iraqi adults, WHpR has the strongest association with type 2 DM and WHtR for hypertension.

Abstract
Background Anthropometric evaluation is an essential feature of geriatric nutritional evaluation for determining malnutrition, being overweight, obesity, muscular mass loss, fat mass gain and adipose tissue redistribution. Anthropometric indicators are used to evaluate the prognosis of chronic and acute diseases, and to guide medical intervention in the elderly. We evaluated anthropometric measurements and nutritional status as they relate to age and gender in healthy elderly people. Methods The study analyzed data from the national survey "Health needs and health service use by older-than-60-year-old beneficiaries of the Mexican Institute of Social Security (IMSS)". The present study included only individuals who reported no chronic disease in the last 20 years and had no hospital admission in the two months prior to the survey. Anthropometric measurements included weight, height, body mass index (BMI), body circumference (arm, waist, hip and calf), waist to hip ratio (WHR), elbow amplitude and knee-heel length. Results Application of the inclusion criteria resulted in a study population elderly of 1,968, representing 12.2% of the original number in the national survey in urban areas beneficiaries of the IMSS. The study population comprised 870 women and 1,098 men, with a mean age of 68.6 years. The average weights were 62.7 kg for women and 70.3 kg for men (p < 0.05), and the mean heights were 1.52 m for women and 1.63 m for men (p < 0.05). Age related changes in anthropometric values were identified. BMI values indicated that 62.3% of the population was overweight, and 73.6% of women and 16.5% of men had high fat tissue distribution. Conclusion Our findings suggest that applying the BMI thresholds that identify being overweight in the general adult population may lead to an overestimation in the number of overweight elderly Similar problems appear to exist when assessing waist circumference and WHR values. Prospective studies are required to determine the associations between health and BMI, waist circumference and WHR in the elderly.

Abstract
BACKGROUND Obtaining accurate height and, consequently, body mass index (BMI) measurements in elderly subjects can be difficult due to changes in posture and loss of height during ageing. Measurements of other body segments can be used as an alternative to estimate standing height, but population- and age-specific equations are necessary. OBJECTIVE Our objectives were to validate existing equations, to develop new simple equations to predict height in an elderly Spanish population and to assess the accuracy of the BMI calculated by estimated height from the new equations. METHODS We measured height and demi-span in a representative sample of 592 individuals, 271 men and 321 women, 65 years and older (mean +/- SD, 73.8 +/- 6.3 years). We suggested equations to predict height from demi-span by multiple regression analyses and performed an agreement analysis between measured and estimated indices. RESULTS Height estimated from demi-span correlated significantly (p < 0.001) with measured height (men: r = 0.708, women: r = 0.625). The best prediction equations were as follows: men, height (in cm) = 77.821 + (1.132 x demi-span in cm) + (-0.215 x 5-year age category); women: height (in cm) = 88.854 + (0.899 x demi-span in cm) + (-0.692 x 5-year age category). No significant differences between the mean values of estimated and measured heights were found for men (-0.03 +/- 4.6 cm) or women (-0.02 +/- 4.1 cm). The BMI derived from measured height did not differ significantly from the BMI derived from estimated height either. CONCLUSION Predicted height values from equations based on demi-span and age may be acceptable surrogates to derive accurate nutritional indices such as the BMI, particularly in elderly populations, where height may be difficult to measure accurately.

Abstract
OBJECTIVES To evaluate gender differences in nutritional risk of older people admitted to an acute-care general medical department, and identify gender-specific risk factors. DESIGN Cross-sectional study. SETTING Internal Medicine Department in an acute care, university-affiliated hospital in southern Israel. SUBJECTS 204 cognitively intact patients aged 65 and over, admitted during a 12-month period to a general medical department. MEASURES OF OUTCOME Evaluation included demographic and clinical data consisting of the sum of medical conditions and of prescribed medications, evaluation of nutritional status, cognitive status, depression assessment and functional ability. Statistical analyses were conducted to evaluate the gender specific risk factors for under-nutrition. RESULTS 32.5% of the men and 48.1% of the women admitted to an internal medicine department were at risk for under-nutrition. Those at nutritional risk had a higher rate of depression, lower cognitive and physical ability, poorer reported health status and more diagnosed diseases. Nutritional risk for men was associated with higher depression score, longer hospitalization, and poor appetite. For women, nutritional risk was associated with lower functional status and more diagnosed diseases. In a multivariate analysis, being a female increased the risk of under-nutrition by 3.3 fold. CONCLUSION Risk of under-nutrition is prevalent among older in-patients and is gender-related. Female inpatients are at markedly increased risk for under-nutrition. The mechanism of the gender discrepancy in factors related to nutritional deterioration is complex and poorly understood.

Abstract
The aim of this study was to explore the relationship among components of the metabolic syndrome and their role in the development of diabetes. We included 2295 subjects, aged 65-84 years, participating in the Italian Longitudinal Study on Aging, a population-based study conducted in 1992 and with a follow-up in 1996. Factor analysis was conducted, separately for diabetic and non-diabetic men and women, using the principle components method and varimax rotations. Factor scores for the baseline were used as independent variables in logistic regressions models to determine risk factors predicting the development of diabetes. Factor analysis among non-diabetic elderly showed two factors for men (body size/insulin resistance, blood pressure/lipids) and three for women (body size, lipids, blood pressure). Among diabetic subjects, three factors emerged for men (body size/lipids/insulin resistance, body size/blood pressure, glucose) and four for women (body size/lipids/insulin resistance, lipids, body size/glucose/insulin resistance, lipids/blood pressure). For non-diabetic men and women, the body size factor (body size/insulin resistance factor for men) was strongly associated with diabetes incidence (OR=2.30, 95% CI 1.41-3.74 and OR=2.06, 95% CI 1.33-3.17, respectively). This study confirms that the metabolic syndrome (MetS) does not recognize one single underlying factor in an elderly cohort and that the obesity factor is a strong predictor of development of new onset diabetes.

Abstract
The objective of this study was to identify the relationship between the oral condition and nutritional status of all institutionalized elderly people in Florianópolis, Brazil. Of the population of 232 institutionalized individuals, the sample consisted of 187 elderly people. In the oral evaluation, the criteria used was the number of functional units present in the oral cavity, classifying the participants as those with highly compromised dentition (48%) and those with less-compromised dentition (52%). Diagnosis of nutritional status was carried out according to body mass index, observing a prevalence of 14% thin, 45% eutrophic, 28% overweight, and 13% obese. Statistical analysis of the variables studied was carried out by means of chi(2) association tests. There was a statistically significant association between highly compromised dentition and thinness (P=0.007) and among those who presented less-compromised dentition and the nutritional status of overweight, including obesity (P=0.014). It was concluded that compromising of the teeth could contribute to a tendency toward inadequate nutritional status.

Abstract
BACKGROUND Pressure ulcers among elderly hospital patients diminish quality of life and increase the cost of hospital care. Evidence suggests that pressure ulcers can arise after only a few hours of immobility. The goals of this study were to estimate the incidence of hospital-acquired pressure ulcers in the first 2 days of the hospital stay and to identify patient characteristics associated with higher incidence. METHODS A prospective cohort study was performed between 1998 and 2001. A total of 3233 patients 65 years old or older admitted through the Emergency Department to the inpatient Medical Service at two study hospitals were examined by a research nurse on the third day of hospitalization. Pressure ulcers were ascertained using standard criteria and were classified as either preexisting, possibly hospital-acquired, or definitely hospital-acquired. RESULTS There were 201 patients with one or more possibly or definitely hospital-acquired pressure ulcers for a cumulative incidence of 6.2% (95% confidence interval, 5.4%-7.1%). Most of the pressure ulcers were stage 2, and the majority were in the sacral area or on the heels. In multivariable analysis, pressure ulcer incidence was significantly associated with increasing age, male gender, dry skin, urinary and fecal incontinence, difficulty turning in bed, nursing home residence prior to admission, recent hospitalization, and poor nutritional status. CONCLUSIONS A small but significant proportion of elderly emergently admitted hospital patients acquire pressure ulcers soon after their admission. New models of care may be required to ensure that preventive interventions are provided very early in the elderly person's hospital stay.

Abstract
OBJECTIVE To examine the relationship between self-reported and clinical measurements for height and weight in adults aged 18 years and over and to determine the bias associated with using household telephone surveys. METHOD A representative population sample of adults aged 18 years and over living in the north-west region of Adelaide (n = 1,537) were recruited to the biomedical cohort study in 2002/03. A computer-assisted telephone interviewing (CATI) system was used to collect self-reported height and weight. Clinical measures were obtained when the cohort study participants attended a clinic for biomedical tests. RESULT Adults over-estimated their height (by 1.4 cm) and under-estimated their weight (by 1.7 kg). Using the self-report figures the prevalence of overweight/ obese was 56.0% but this prevalence estimate increased to 65.3% when clinical measurements were used. The discrepancy in self-reported height and weight is partly explained by 1) a rounding effect (rounding height and weight to the nearest 0 or 5) and 2) older persons (65+ years) considerably over-estimating their height. CONCLUSION Self-report is important in monitoring overweight and obesity; however, it must be recognised that prevalence estimates obtained are likely to understate the problem. IMPLICATIONS The public health focus on obesity is warranted, but self-report estimates, commonly used to highlight the obesity epidemic, are likely to be underestimations. Self-report would be a more reliable measure if people did not round their measurements and if older persons more accurately knew their height.

Abstract
OBJECTIVE In the clinical practice, visceral proteins are used as indirect markers of protein energy malnutrition (PEM), but their reliability could be reduced with advancing age. The aim of this work is to investigate the reliability of albumin, prealbumin, retinol-binding protein (RBP) and transferrin in evaluating nutritional status in old patients and their relationship with fat-free mass (FFM). DESIGN Cross-sectional study. SETTING Padua, Italy. SUBJECTS In 44 underweight (body mass index < 20 kg/m(2)) (66-97 years) and 69 normal weight or overweight elderly subjects (62-98 years), albumin, prealbumin, transferrin and RBP were determined in the plasma. Body composition and particularly FFM was obtained by dual X-ray absorptiometry. FFM was also expressed as FFM index (FFMI) calculated as FFM divided by height squared. Subjects affected by acute illnesses and inflammatory states were excluded. RESULTS Albumin, prealbumin and RBP mean values were significantly lower in underweight subjects. No differences between two groups were found for transferrin. Albumin prealbumin and RBP resulted under the normal range in 55, 25 and 54% of underweight subjects, respectively. Transferrin's values were low in about 40% of underweight and normal weight subjects, respectively. In all subjects, FFMI shows a significant correlation with albumin (r: 0.52), prealbumin (r: 0.64) and RBP (r: 0.57). No correlation between FFMI and transferrin was found. CONCLUSIONS Visceral proteins, except for transferrin, seem to be useful indexes in detecting malnutrition in the elderly; low values still in the normal range should also be carefully evaluated because they could suggest a poor nutritional status.

Abstract
The aim of this large, cross-sectional study was to describe the age- and sex-related variations of the somatotype, employing Heath and Carter's method, in a Chuvasha population residing in a rural region in central Russia. The investigated sample included 802 males aged 18-89 years (mean 46.9) and 738 females aged 18-90 years (mean 48.6). We evaluated the age and sex differences by one-way ANOVA with somatotype components as dependent variables and sex or age groups as grouping variables. Sex differences of somatotypes appear to be the strongest for endomorphy, with generally higher values in women. Endomorphy in males remained virtually unchanged after 30 years of age, but endomorphy in females kept increasing up to the 6th decade, and then subsequently decreased. Virtually no differences were noted in mesomorphy and a very small difference in ectomorphy between males and females aged 18-30 years. A reduction of sexual dimorphism in all somatotype components after age 70 was also observed. The largest difference of all somatotype components appeared between age groups 18-30 and 31-40 years. Thereafter, somatotypes remained practically unchanged. Mesomorphy continued to increase until the 5th decade in both sexes, while in females, endomorphy continuously increased until their 6th decade. In the 7th and 8th decades, a decrease in mean values was observed. Mesomorphy and ectomorphy showed opposite age-related trends. Results of our study clearly suggest that in physique investigations, the somatotypes need to be studied in each sex separately, and in studies of young people, they need also to be adjusted to age.

Abstract
Evolutionary biology has rejected any argument in favour of planned ageing. In this article, the metabolic changes that follow in ageing have been analysed, and in accordance with that, an evolutionary explanation for the senescence program has been proposed. Ageing is characterised by a set of metabolic features all of them designed to reduce energy expenditure and to promote energy storage. Otherwise, the undoubted beneficial effect to fitness that means to live longer could generate a conflict between parents and offspring for energy resources. The solution to that conflict is an adult economical individual, a "thrifty aged". The way to obtain this cheaper individual is through the genetically induced physiological changes that finally lead the process. In conclusion, it is proposed that ageing is the condition, imposed by natural selection, that let organisms to outlast the obligatory reproductive time.

Abstract
PURPOSE Studies have shown a high prevalence of weight loss in older adults is associated with an increased risk of death. We investigated this in a population-based study. METHODS Persons living in Beaver Dam, Wisconsin, participated in a baseline examination between 1988 and 1990 (n=4926). A medical examination and standardized questionnaire were administered. Weight loss was defined as percent loss in body weight from highest lifetime weight to measured weight at baseline. RESULTS Weight loss was associated with older age, higher rates of diseases such as diabetes, and lower baseline levels of blood pressure and serum total cholesterol. After controlling for age, medical, and lifestyle factors, both men and women had higher mortality rates over a 10+ year period for increasing categories of weight loss (hazard ratio [ 95% CI]: 1.16 [1.06, 1.27] for men and 1.23 [1.13, 1.34] for women). Increased mortality rates with increasing weight loss was shown in stratified analyses of age, body mass index (BMI) at highest weight, smoking, and disease status, but did not always reach statistical significance. Persons on weight loss diets within the year prior to baseline did not have increased mortality with increasing weight loss. CONCLUSION The strong association between weight loss (likely involuntary) and mortality may be a useful way of estimating overall risks to longevity in populations.

Abstract
The article presents gender and age-specific selected anthropometric data for a representative sample of elderly Brazilians in the city of São Paulo. This was a cross-sectional, population-based household survey. A total of 1,894 older adults (men and women, > 60 years) were examined from January to March 2001. Data were presented as means and percentiles for body mass (BM); height or stature (ST); body mass index (BMI); waist (WC), hip (HC), arm (AC), and calf (CC) circumferences; triceps skinfold thickness (TST); and arm muscle circumference (AMC), and differences were described according to age (all variables) and gender (BMI). Except for HC (men), all anthropometric variables were lower in the oldest than in the youngest individuals (p < 0.01) in both genders. BMI was significantly higher (p < 0.01) in women than men (all age groups). The observations suggest that there is loss of muscle mass and redistribution and reduction of fat mass with age (both genders). The data can be used in clinical practice and epidemiological studies based on interpretation of anthropometric measurements in the elderly in São Paulo.

Abstract
OBJECTIVE Nutritional deficiency is an independent risk factor for mortality. Despite its clinical relevance, the prevalence in a primary care setting is poorly documented. We performed a systematic review of reported prevalence and clinical assessment of nutritional deficiency in general practice. METHODS From MEDLINE, Current Contents and EMBASE, we derived articles and checked the initially included ones for references on prevalence data. Of the eligible articles, we assessed the quality of research and results. RESULTS We finally included eight studies. The prevalence ranged from 0 to 13%. However, the study populations were heterogeneous and all studies contained methodological flaws, especially selection bias. In addition, the clinical assessment differed between studies. CONCLUSION Literature on the prevalence of nutritional deficiency within general practice is rare and provides disputable prevalence assessments.

Abstract
BACKGROUND AND OBJECTIVE Our purpose was to examine sociodemographic factors and lifestyle customs associated with weight change in the older adult population of Spain. SUBJECTS AND METHOD Prospective cohort study conducted from 2001 to 2003 among a cohort of 2,384 people representative of the non-institutionalized Spanish population aged 60 years and over. Data were collected through home interviews, and main statistical analysis was performed through polytomous logistic regression. RESULTS Over the 2-year follow-up, 27.9% of men and 27.3% of women lost > or = 3 kg, and 18.2% of men and 16.9% of women gained > or = 3 kg. Among men, a loss of > or = 3 kg was more likely among former smokers (odds ratio [OR] = 1.58; 95% confidence interval [CI], 1.13-2.23) and among those with higher body mass index (BMI) (p for linear trend < 0.0001). A weight gain of > or = 3 kg was also more frequent in former smokers (OR = 1.93; 95% IC, 1.28-2.90). In addition, the risk of gaining > or = 3 kg decreased progressively with the increase in the frequency of physical activity at leisure time (p for linear trend < 0.0001). Among women, results were similar to those in men, though in former smokers there was no association with weight changes. CONCLUSIONS In the older adult population, BMI, physical activity at leisure time, and a former smoker status are associated with weight change in the short term. Intervention on physical activity should be a priority, because it is the main modifiable factor, is associated with health-related quality of life, and it could contribute to avoid excess weight.

Abstract
BACKGROUND The present study aims at defining a body mass index (BMI) threshold for risk of being underweight in elderly persons on the basis of the BMI distribution in a large Italian population-based sample and on its ability to predict short-term mortality. METHODS At baseline (1992), BMI was obtained for 3110 (1663 males and 1447 females) persons aged 65-84 participating in the Italian Longitudinal Study on Aging (ILSA). BMI and risk factors (age, sex, education, smoking status, disability, and disease status) have been considered for their potential association with 4-year all-cause mortality. Information on vital status at 1995 was obtained for 2551 participants. RESULTS The fifth centile of BMI was well approximated by a value of 20 for both sexes. Also in both sexes, at a BMI value of 24 the a posteriori probability of death started to increase, doubling at a value of 22 for men and 20 for women. Crude mortality was 14.6% for men and 9.8% for women. The hazard ratios and confidence intervals (CIs) comparing mortality for each BMI two-unit class to the 26-28 class, after adjusting for confounding variables, showed significantly higher rates only for BMI values below 20 (2.9; 95% CI, 1.2-7.0), although a consistent increase in hazard ratio (1.6; 95% CI, 0.9-3.0) already appeared for the 20-22 BMI group. CONCLUSIONS Our study confirms that low BMI is an independent predictive factor of short-term mortality in elderly persons. A BMI value of 20 kg/m2 seems to be a reliable threshold for defining underweight elderly persons at high risk. Nevertheless, more careful clinical and nutritional management should also be applied to elderly persons with higher BMI values.

Abstract
BACKGROUND Body mass index (BMI) and waist circumference are highly correlated. One or the other predicts the metabolic syndromes better, depending on characteristic of the population studied, such as age, gender, and ethnicity. We examined the impact of isolated central obesity, isolated BMI elevation, and the combined type of obesity on metabolic disorders, in order to shed lights on the strategy of obesity screening. METHODS The study subjects were Chinese aged 20 or above residing in Taiwan. Their data were derived from two large-scale studies: the Nutrition and Health Survey in Taiwan (NAHSIT 1993-1996) and the Cardiovascular Disease Risk Factor Two-township Study (CVDFACTS, 1994-1997). In evaluating the relations between obesity and health risks, the cut-points of BMI (> or =24 kg/m(2) for overweight) and waist circumference (> or =80 cm for women and > or =90 cm for men) recommended by Department of Health in Taiwan for Taiwanese people were used to define various types of obesity. RESULTS We found that there was a small but nontrivial proportion (1.7% for men and 4.0% for women) of Taiwanese people for whom BMI was in the normal range but their waist circumferences were above normal. These people were at a higher risk of developing metabolic syndromes than those with isolated BMI elevation. Their risks were close to that of the combined type. CONCLUSIONS In order to screen out high-risk obese individuals, isolated centrally obese subjects should not be overlooked. Therefore, we recommend to assess waist circumference in parallel to, not just sequential to the measurement of BMI in Chinese.

Abstract
OBJETIVO: O objetivo deste trabalho foi avaliar a correlação entre o índice de massa corporal e indicadores antropométricos de distribuição de gordura em adultos e idosos. MÉTODOS: Trata-se de um estudo transversal, constituído por 634 indivíduos (316 adultos e 318 idosos) de ambos os sexos, atendidos nos ambulatórios do Hospital das Clínicas da Universidade Federal da Bahia (Salvador, BA). Mediram-se em cada indivíduo: peso, altura, pregas cutâneas triciptal e subescapular, circunferências de quadril e cintura, segundo técnicas propostas por Lohman, em 1988. Utilizou-se o teste de correlação de Pearson para avaliar a correlação entre o índice de massa corporal e os indicadores antropométricos de distribuição de gordura. RESULTADOS: As correlações entre o índice de massa corporal e a circunferência da cintura nos dois grupos etários do sexo masculino foram: de adultos (r = 0,93; p<0,001); de idosos (r = 0,89; p<0,001). Para os grupos do sexo feminino, as correlações foram: grupo de adultas (r = 0,93; p<0,001), de idosas (r = 0,86; p<0,001). A correlação entre o índice de massa corporal e a razão cintura quadril foi menor, mas estatisticamente significante, entre os dois grupos de cada sexo. Assim, para o sexo masculino, entre o grupo adulto (r = 0,64; p<0,001) e no idoso (r = 0,63; p<0,001); e para o feminino, entre os grupos: adultas (r = 0,66; p<0,001) e idosas (r = 0,34; p<0,001). CONCLUSÃO: O índice de massa corporal apresentou correlação positiva e forte com a circunferência da cintura nos dois grupos etários e em ambos os sexos. Apesar de estatisticamente significante, o índice de massa corporal se correlacionou de forma menos intensa com a razão cintura quadril, principalmente no grupo das mulheres idosas.

Abstract
Somatotyping is an effective technique for the study of anthropometric variations and body composition in elderly subjects, even though it has not often been used in this field. The present study was conducted on a sample of 280 healthy Sardinians (134 men and 146 women) of age 60-89 years, subdivided into three age classes (60-69 years; 70-79 years; and 80-89 years). Somatotypes were computed according to Carter and Heath (Somatotyping-Development and Applications. Cambridge, England: Cambridge University Press; 1990). The results show a dominance of the endo- and mesomorphic components in the elderly subjects, with less development of ectomorphy than in younger individuals. In a comparison with other populations, our sample shows strong development of endomorphy and especially of mesomorphy, while ectomorphy values are generally low. Age-related variations are significant in both sexes and consist in a progressive reduction of the endomorphic component, particularly in the 80-89-year class (endomorphy in the three age classes: 6.4, 6.1, and 5.3 in men; 8.1, 7.8, and 6.8 in women). The mesomorphic component is characterized by stability (age variations: 6.4, 6.4, and 5.9 in men; 6.3, 6.4, and 6.3 in women) and the ectomorphic component by a slight increase (age variations: 0.5, 0.6, and 0.8 in men; 0.4, 0.3, and 0.5 in women). Sex differences are significant and especially large for the endomorphic component, with generally higher values in women. The sexual dimorphism tends to decrease with age. The results are discussed with regard to the biology of aging, with emphasis on the potential application of somatotype to studies of the elderly population.

Abstract
A avaliação do estado nutricional do idoso é considerada complexa em razão da influência de uma série de fatores, os quais necessitam ser investigados, detalhadamente, visando diagnóstico nutricional acurado, que possibilite intervenção nutricional adequada. Alterações fisiológicas, processos patológicos crônicos e situações individuais que ocorrem com o envelhecimento, geralmente interferem no estado nutricional do indivíduo. Portanto impõe-se uma associação de indicadores nutricionais e a utilização de padrões de referência os mais específicos possíveis para realizar-se tal avaliação. Com o objetivo de contribuir ao estudo nutricional do indivíduo idoso, este trabalho discute os principais aspectos relacionados à avaliação do estado nutricional, com ênfase nos indicadores e critérios de avaliação mais apropriados para esse grupo etário, considerando-se as modificações inerentes ao processo de envelhecimento.

Abstract
BACKGROUND AND AIMS In underweight elderly subjects it is important to estimate body composition and particularly fat-free mass (FFM). Bioelectrical impedance analysis (BIA) is a non-invasive method in determining FFM, but its usefulness in these frail subjects should be verified. The aim of this study is to verify in underweight elderly people the reliability of previously published BIA formulas in detecting FFM. METHODS Fifty-seven hospitalized elderly subjects (27 males and 30 females) with body mass index <20 kg/m(2) were selected. In all subjects, FFM was detected by dual energy X-ray absorptiometry. Moreover, BIA measurements were performed at standard frequency (50 kHz and 800 microA) and FFM was derived using the main previous published BIA equations. RESULTS In men, Kyle and Rising equations gave acceptable estimates of FFM with a mean error, respectively, of 1+/-1.9 and 1.4+/-1.7 kg. Also RJL formula could be used after adjusting for a correction factor. In women, no equation seemed sufficiently reliable to estimate FFM. CONCLUSIONS BIA method seems useful to evaluate body composition in underweight elderly men but it seems to have intrinsic limits in women. Nevertheless, the variability in behavior of the different equations suggests to be careful in adopting BIA equations.

Abstract
OBJECTIVE There are few studies on anthropometry and nutritional status in large and representative samples of elderly populations in Chile and South America. We describe age and sex differences in weight, height, body mass index, knee height, waist circumference, midarm circumference, triceps skinfold thickness, arm muscle area, and calf circumference in Chilean elderly subjects. METHODS This was a population-based, cross-sectional study. A total of 1220 elderly persons (819 women and 411 men; age range, 60-99 y) were recruited in the city of Santiago (Chile) through a probabilistic sampling procedure carried out from October to December 1999. RESULTS Men were significantly heavier and taller than women in all age groups, whereas body mass index values were significantly higher in women than in men. All anthropometric variables showed a decrease in average values with aging in men and women. The apparent negative slopes for the decline in average values of body weight with aging was of greater magnitude in women than in men (-0.42 kg/y and -0.54 kg/y in male and female subjects, respectively). However, significant age x sex interaction was detected only for triceps skinfold thickness. In women, quadratic terms for age provided a significantly better fit than did the simple linear model for the association between age and weight, body mass index, waist circumference, triceps skinfold thickness, calf circumference, or midarm circumference. CONCLUSION These observations indicated that body weight changes associated with aging might be more severe in Chilean women than in men, probably determining a differential pattern of lean and fat mass loss.

Abstract
PURPOSE OF REVIEW To investigate emerging data on the relationship between obesity, increased morbidity and mortality, and decreased function in the elderly. To examine what is known about the effectiveness of interventions, and how treatment might be improved. RECENT FINDINGS Obesity is a common problem in the elderly, although its prevalence decreases in extreme old age. Decreased physical activity and decreased energy expenditure with ageing predispose to fat accumulation and fat redistribution. Reduction in muscle mass (sarcopenic obesity) is an important determinant of physical function and metabolic rate. Chronic inflammation and endocrine changes contribute to the changes in metabolism and body composition that accompany ageing, and are potential therapeutic targets. Body weight and body mass index are imperfect indicators of risk from obesity. The focus of treatment should be on reduction of intra-abdominal fat and preservation of muscle mass and strength. A number of recent studies have confirmed the effectiveness of exercise interventions in the elderly. Progressive resistance training, rather than endurance exercise, may be more effective in many cases. Reduced function and decreased quality of life accompany development of the complications of obesity such as diabetes and vascular disorders. There is considerable scope to impede the development of these complications in the elderly with lifestyle interventions. SUMMARY Sarcopenic obesity, with accumulation of intra-abdominal fat, is a major determinant of health status in the elderly. As in the younger population, prevention and treatment programmes have the potential to decrease the impact of diabetes, vascular disease, and other complications of obesity.
