RESUMEN
Abstract Objective: To compare the measurements of the lumbar safety triangle (Kambin's triangle) and the invasion of the dorsal root ganglion in the triangle in coronal and coronal oblique planes. Materials and Methods: A cross-sectional study, in which 210 3.0-T magnetic resonance images of L2-L5 were analyzed in coronal and coronal oblique planes. Exams with lumbar spine anomalies were excluded. Demographic (sex and age) and radiological variables were recorded by a single evaluator. Results: Most sample was female (57.1%), mean age 45.5 ± 13.3 (18-98 years). The measurements average, as well as the areas, gradually increased from L2 to L5. The dorsal root ganglion invaded the triangle in all images. The safety triangle average area was smaller in the coronal oblique plane than in the coronal plane. Of the seven dimensions of safety triangle obtained for each level of the lumbar spine, six were significantly smaller in the coronal oblique plane than in the coronal plane. The only dimension that showed no difference was the smallest ganglion dimension. Conclusion: The dimensions and areas investigated were smaller in coronal oblique plane, especially the area (difference > 1 mm). The analysis of the triangular zone in this plane becomes important in the preoperative assessment of minimally invasive procedures.
Resumo Objetivo: Comparar as medidas do triângulo de segurança lombar (triângulo de Kambin) e invasão do gânglio da raiz dorsal no triângulo nas incidências coronal e coronal oblíqua. Materiais e Métodos: Estudo transversal, em que foram analisadas 210 imagens de ressonância magnética 3.0-T de L2-L5 nos planos coronal e coronal oblíquo. Foram excluídos exames com anomalias da coluna lombar. Variáveis demográficas (sexo e idade) e radiológicas foram registradas por um único avaliador. Resultados: A maioria da amostra era do sexo feminino (57,1%), com idade média de 45,5 ± 13,3 (18-98 anos). A média das medidas, assim como as áreas, aumentaram gradativamente de L2 a L5. O gânglio da raiz dorsal invadiu o triângulo em todas as imagens. A área média do triângulo de segurança foi menor na incidência coronal oblíqua do que na incidência coronal. Das sete dimensões do triângulo de segurança obtidas para cada nível da coluna lombar, seis foram significativamente menores no plano coronal oblíquo do que no plano coronal. Única dimensão que não apresentou diferença foi a menor dimensão do gânglio. Conclusão: As dimensões e áreas investigadas foram menores na incidência coronal oblíqua, especialmente a área (diferença > 1 mm). A análise da zona triangular nesta incidência torna-se importante na avaliação pré-operatória de procedimentos minimamente invasivos.
RESUMEN
OBJECTIVES: This study aimed to verify the performance of the triglyceride-glucose (TyG) index in predicting metabolic syndrome (MetS) using three different criteria in healthy individuals living in rural areas. In addition, it aimed to estimate the TyG index cutoff point in the prediction of MetS. METHODS: The study was a cross-sectional study of healthy individuals (aged ≥18 y) living in rural areas of southern Brazil. Individuals with diabetes mellitus were excluded. The variables investigated were waist circumference, blood pressure, triglycerides, high-density lipoprotein cholesterol, fasting glucose, and TyG index. MetS was defined using three criteria: harmonized, International Diabetes Foundation, and National Cholesterol Education Program Adult Treatment Panel III. The Poisson regression model was used for the multivariate analysis. The performance of the TyG index in identifying MetS was determined by receiver operating characteristic curves. RESULTS: A total of 133 individuals were included in this study, with a mean age of 49.0 ± 13.5 y; 54.1% were female. The TyG index performed better in predicting MetS through the harmonized criteria, with area under the curve (AUC) = 0.889 (95% confidence interval [CI], 0.829-0.949), followed by the International Diabetes Foundation criteria, with AUC = 0.877 (95% CI, 0.814-0.940), and the National Cholesterol Education Program criteria, with AUC = 0.867 (95% CI, 0.797-0.937). The TyG index cutoff points defined for the harmonized and International Diabetes Foundation criteria were ≥ 8.61, and ≥ 8.79 for the National Cholesterol Education Program Adult Treatment Panel III. CONCLUSIONS: The TyG index proved to be valid for diagnosing MetS. The largest AUC of the TyG index was identified for the harmonized criteria. Thus, the TyG index can be used to diagnose MetS in individuals living in rural areas.

RESUMEN
Adherence to lifestyle changes is a major challenge for healthcare professionals. The transtheoretical model (TTM) was proposed to promote behavioral changes, used in different health conditions (smoking, alcoholism, drug addiction, and obesity) and age groups. However, the effectiveness of the model in older persons is not yet known. This systematic review protocol follows the PRISMA-P guidance. The question the review will address is, Are interventions based on the TTM, compared with conventional interventions, associated with lifestyle changes in older adults? Databases MEDLINE/PubMed, EMBASE, LILACS, CENTRAL, WoS, and PsycINFO will be searched. Randomized clinical controlled trials and quasi-experimental studies describing the effectiveness of TTM-based interventions in changing the lifestyle of individuals aged 65 and over, compared with conventional interventions for lifestyle changes, will be included. Studies that do not address the stages of change characteristic of TTM or that use pharmacological interventions as a comparator will be excluded. Reviewers independently will screen papers for eligibility criteria, and, extracting data, assess the risk of bias for included studies and will evaluate the overall quality of evidence (GRADE system). If possible, a meta-analysis will be conducted. Otherwise, a narrative synthesis will be prepared according to the SWiM guideline.

Background and Objectives: The search for simple and rapid screening indicators for metabolic syndrome (MS) is important due to its high frequency in the adult population. And this aspect is little explored in the rural Brazilian population. The objective of this study was to verify the relationship of MS components with lipid indices and anthropometric parameters in rural workers. Methods: Cross-sectional study with rural workers aged 18 years or older. The MS was determined through harmonized criteria. The fasting glucose (GLI), systolic (SBP) and diastolic (DBP) blood pressure, HDL-c and waist circumference (WC); anthropometric parameters: body mass index (BMI), waist/height ratio (WHtR) and body fat percentage (%F); and lipid indices: glycemic triglyceride index (TyG), lipid accumulation product (LAP) and visceral adiposity index (VAI). Exploratory factor analysis was performed that included, in model I, the anthropometric parameters and, in model II, the lipid indices. Results: out of the 167 workers, 21.0% were older adults (≥60 years), 39.5% were male and 61.1% had MS, with a higher prevalence in females. Model II responded to the highest explained variance (78.43%) including metabolic (VAI, LAP, TyG and TG and -HDL-c), cardiometabolic (SBP, DBP and CC) and glycemic factors. Model I explained 70.4% of the variance, which included excess weight, blood pressure and lipid/glycemic factors. Conclusion: the model that included the lipid indices explained the greatest variance observed and the VAI presented the most significant load of this factor.(AU)

O objetivo deste estudo foi verificar a relação dos componentes da SM com índices lipídicos e parâmetros antropométricos em trabalhadores rurais. Métodos: Estudo transversal com trabalhadores rurais com 18 anos ou mais. A SM foi determinada pelo critério harmonizado. Foram investigados os seguintes componentes da SM: triglicerídeos (TG), glicose em jejum (GLI), pressão arterial sistólica (PAS) e diastólica (PAD), HDL-c e circunferência da cintura (CC); os parâmetros antropométricos: índice de massa corporal (IMC), relação cintura/estatura (RCE) e percentual de gordura corporal (%G); e os índices lipídicos: índice triglicerídeos glicemia (TyG), produto de acumulação de lipídios (LAP) e índice de adiposidade visceral (VAI). Foi realizada análise fatorial exploratória que incluiu, no modelo I, os parâmetros antropométricos e, no modelo II, os índices lipídicos. Resultados: Dos 167 indivíduos investigados, 21,0% eram idosos (≥60 anos), 39,5% do sexo masculino e 61,1% apresentaram SM, com maior frequência no sexo feminino. O modelo II respondeu a maior variância explicada (78,43%) incluindo os fatores metabólico (VAI, LAP, TyG, TG e o -HDL-c), cardiometabólico (PAS, PAD e CC) e glicêmico. O modelo I explicou 70,4% da variância, que incluiu os fatores excesso de peso, pressão arterial e lipídico/glicêmico. Conclusão: o modelo que incluiu os índices lipídicos explicou a maior variância observada e o VAI apresentou a carga mais significativa desse fator.(AU)

OBJECTIVES: The aim of this study was to verify the accuracy of the SARC-F and the SARC-CalF as screening tools for sarcopenia in community-dwelling older women ≥60 y of age. METHODS: This was a cross-sectional study evaluating a convenience sample of women ≥60 y of age, living in Southern Brazil. Sarcopenia was defined according to the criteria proposed in the latest European Working Group on Sarcopenia in Older People consensus (EWGSOP2). Appendicular muscle mass was assessed by dual-energy x-ray absorptiometry. Muscle strength was measured by handheld dynamometry, and physical performance through the 4-m gait speed test. The SARC-F questionnaire and SARC-CalF score for sarcopenia screening were also applied. RESULTS: We evaluated 288 participants, with a mean age of 67.6 ± 5.8 y. The frequency of probable and confirmed sarcopenia in the sample was 7.3% and 2.1%, respectively. The frequency of risk for sarcopenia assessed by the SARC-F was 4.5% and SARC-CalF 22.2%. Despite the excellent specificity (95.4%) demonstrated by the SARC-F, its sensitivity in identifying confirmed cases was null, whereas the SARC-CalF showed high sensitivity (83.3%) and good specificity (79%). CONCLUSION: The present study findings suggested that SARC-CalF may be able to outperform SARC-F as a sarcopenia screening tool in women ≥60 y of age even under the new EWGSOP2 criteria, the main determinant of which is strength as observed in studies based on the previous definition.

BACKGROUND: Age-related sensory loss and frailty are common conditions among older adults, but epidemiologic research on their possible links has been inconclusive. Clarifying this relationship is important because sensory loss may be a clinically relevant risk factor for frailty. METHODS: In this systematic review and meta-analysis, we searched 3 databases for observational studies investigating 4 sensory impairments-vision (VI), hearing (HI), smell (SI), and taste (TI)-and their relationships with frailty. We meta-analyzed the cross-sectional associations of VI/HI each with pre-frailty and frailty, investigated sources of heterogeneity using meta-regression and subgroup analyses, and assessed publication bias using Egger's test. RESULTS: We included 17 cross-sectional and 7 longitudinal studies in our review (N = 34,085) from 766 records. Our cross-sectional meta-analyses found that HI and VI were, respectively, associated with 1.5- to 2-fold greater odds of pre-frailty and 2.5- to 3-fold greater odds of frailty. Our results remained largely unchanged after subgroup analyses and meta-regression, though the association between HI and pre-frailty was no longer significant in 2 subgroups which lacked sufficient studies. We did not detect publication bias. Longitudinal studies largely found positive associations between VI/HI and frailty progression from baseline robustness, though they were inconclusive about frailty progression from baseline pre-frailty. Sparse literature and heterogenous methods precluded meta-analyses and conclusions on the SI/TI-frailty relationships. CONCLUSIONS: Our meta-analyses demonstrate significant cross-sectional associations between VI/HI with pre-frailty and frailty. Our review also highlights knowledge gaps on the directionality and modifiability of these relationships and the impact of SI/TI and multiple sensory impairments on frailty.

ABSTRACT Objective: To evaluate the lumbar triangular safety zone, its boundaries and its relationship with the dorsal root ganglion through Magnetic Resonance Imaging (MRI). Methods: The boundaries, shape and dimensions of 303 triangular safety zones were analyzed in Tesla 3.0 Magnetic Resonance Imaging (MRI) coronal sections from L2 to L5, including the dorsal root ganglion. Results: The sample consisted of 101 patients with a mean age of 32 years. The height of the triangular safety zone was formed by the lateral edge of the dura mater, the width by the upper plateau of the lower vertebra and the hypotenuse by the corresponding nerve root. The mean dimensions and the area varied according to the level studied. The dorsal root ganglion invaded the dimensions of the triangle in all the images studied. Conclusion: Based on the data and the analyses performed, we concluded that knowledge of the boundaries of the triangular safety zone through MRI increases the safety of minimally invasive procedures in the lumbar spine. Level of evidence I; Diagnostic studies - Investigation of a diagnostic test.

Resumo Introdução O tabagismo constitui a principal causa de morte evitável no mundo e é considerado um importante fator de risco para as doenças cardiovasculares (DCV). Objetivo Verificar a associação do tabagismo com sexo, metabolismo redox e fatores de risco cardiometabólicos de 381 idosos da Estratégia Saúde da Família de Porto Alegre/RS. Método Para categorizar o tabagismo, seguiram-se as recomendações do Center of Diseases Control (CDC). Os marcadores de estresse oxidativo investigados foram: produtos avançados da oxidação proteica (AOPP), metabólitos do óxido nítrico (NOx), capacidade antioxidante medida por meio do ensaio ferric reducing ability of plasma (FRAP). Fatores de risco cardiometabólicos também foram avaliados. Resultados Em relação ao sexo/fumo, foram mais frequentes as mulheres não fumantes (P = 0,001). Os homens ex-tabagistas apresentaram maiores concentrações de FRAP (P = 0,001), e os tabagistas, maior concentração de NOx, (0,012), menores médias de circunferência de cintura-CC (P = 0,017) e de índice de massa corporal-IMC (P = 0,003) e maior HDL-c (P = 0,003). Não foram verificados resultados significativos entre as mulheres. Conclusão Os idosos do sexo masculino tabagistas apresentaram menores valores de CC, IMC e HDL-c, porém os tabagistas apresentaram aumento da concentração do NO x, o qual é um biomarcador de estresse oxidativo associado a doenças cardiovasculares. Portanto, é preciso destacar a importância na prevenção e adesão à cessação de tabagismo para evitar comorbidades cardiovasculares.
Abstract Background Smoking is the leading cause of preventable death worldwide, and is considered an important risk factor for cardiovascular disease (CVD). Objective To investigate the association of smoking with sex, redox metabolism and cardiometaboic risk factors of 381 elderly from the Family Health Strategy of Porto Alegre. Method To categorize smoking, followed by the recommendations of the Center for Disease Control (CDC). We studied the following oxidative stress markers investigated: advanced products of protein oxidation (AOPP), nitric oxide metabolites (NOx), the antioxidant capacity was measured by Ferric Reducing Ability of Plasma (FRAP). Cardiometabolic risk factors were also evaluated. Results Regarding sex/smoking, women are more often non-smokers (P = 0.001). Former male smokers had higher concentrations of FRAP (P = 0.001), and smokers had higher concentration of NOx (0.012), lower average waist circumference-WC (P = 0.017), body mass index-BMI (P = 0.003) and increased HDL-c levels (P = 0.003). There were found significant results among women. Conclusion The elderly male smokers presented lower values of WC, BMI and HDL-c, but smokers presented increased NOx concentration, which is a oxidative stress biomarker associated with cardiovascular diseases. Therefore, it is important to emphasize the importance in preventing and adhering to smoking cessation to avoid cardiovascular comorbidities..
RESUMEN
Introduction: Studies have demonstrated the relevance of anthropometric indicators in the prediction of metabolic syndrome (MetS). However, researches involving older people are still scarce. Therefore, the objective was to describe the frequency of MetS and to determine the performance of anthropometric indicators as predictors of MetS in the total sample, in men and women. Methods: Cross-sectional study involving 479 elderly individuals attended in primary health care. The revised National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATPIII) guidelines were used for the MetS diagnosis. The anthropometric indicators evaluated were neck circumference, sagittal abdominal diameter (SAD), SAD/height, sagittal index, and conicity index (C-Index). The predictive performance of the MetS anthropometric indicators was determined using a receiver operating characteristic (ROC) curve. A cutoff point >0.700 was used to evaluate diagnostic performance. Results: The frequency of MetS was 60.5%. The anthropometric indicators demonstrating adequate performance were in total sample: SAD/height (auROC = 0.810), SAD (auROC = 0.777), and C-Index (auROC = 0.706); in women: SAD (auROC = 0.820), SAD/height (auROC = 0.810), neck circumference (auROC = 0.782), and C-Index (auROC = 0.727); in men: SAD/height (auROC = 0.768), SAD (auROC = 0.760), and C-Index (auROC = 0.724). Conclusions: A high frequency of MetS was observed. Of the five anthropometric indicators investigated, three presented good performance in the total sample (SAD, SAD/height, and C-Index), four in women (SAD, SAD/height, neck circumference, and C-Index), and three in men (SAD, SAD/height, and C-Index). The anthropometric indicators, SAD, SAD/height, and C-Index, proved to perform adequately in all the three segments investigated.

OBJECTIVE:: To determine the effects of group exercises on balance, mobility, and depressive symptoms in community-dwelling older adults with mild cognitive impairment. DESIGN:: Single blinded, randomized, matched pairs clinical trial. SETTING:: Four primary healthcare units. SUBJECTS:: Fifty-two sedentary subjects with mild cognitive impairment were paired (age, sex, body mass index, and Addenbrooke's Cognitive Examination Revised score), tested, and then randomized into an intervention group ( n = 26) and a control group ( n = 26). INTERVENTION:: The intervention group performed strength (ankle weights, elastic bands, and dumbbells) and aerobic exercises (walking) in their communities' public spaces, twice a week (60 minutes each), during 24 weeks. The control group maintained its usual routine. MAIN MEASURES:: Balance (Berg Balance Scale (BBS)), mobility (Timed Up and Go Test (TUG)), and depressive symptoms (Geriatric Depression Scale-15) were assessed before and after the intervention. RESULTS:: Before the intervention, the two groups did not differ statistically. After, the intervention group showed significant improvement ( P < 0.05) in balance (before: 53 ± 3; after: 55.1 ± 1.1 points), mobility (before: 10.7 ± 2.9 seconds; after: 8.3 ± 2 seconds), and depressive symptoms (median punctuation (interquartile range) before: 4 (1.8-6); after: 2.5 (1-4)). The control group presented a significant increase in their depressive symptoms (median before: 3.5 (2-7.3); after: 4 (2-5.3)), while their balance and mobility showed no significant modification. Small effect sizes were observed in the intervention group and control group depressive symptoms, as well as in the control group's mobility and balance. Large effect sizes were observed the intervention group's mobility and balance. CONCLUSION:: Group exercises improved balance, mobility, and depressive symptoms in community-dwelling older adults with mild cognitive impairment.

BACKGROUND AND PURPOSE: Mild cognitive impairment (MCI) may be a precursor to dementia; however, its progression may be prevented or slowed with exercise. This study aimed at determining the effects of group aerobic and strength training on cognition, conditioning, muscle endurance, and balance in underprivileged community-dwelling older adults with MCI. METHODS: This was a single-blind, randomized, and matched-pair controlled (gender, age, body mass index, and Addenbrooke's Cognitive Examination-Revised for MCI diagnosis) clinical trial. It was developed in 4 community centers. Fifty-two sedentary, functionally independent individuals, aged 60 years or more, with MCI were randomized into intervention group (n = 26) and control group (n = 26). Participants were tested before and after a 24-week exercise program. Sociodemographic characteristics, cognition (Mini-Mental State Examination), conditioning (2-minute stationary walk test), lower-limb endurance (30-second sit/stand test), and balance data (Functional Reach test) were collected. The intervention group walked and exercised twice weekly (60 minutes each) using ankle weights, latex resistance bands, and dumbbells. The exercise load and intensity were regularly increased on the basis of a preestablished incremental number of sets and repetitions and on the basis of the participants' correct movement execution with a given load. Data were analyzed with Pearson χ test, Fisher exact test, Student t test, Mann-Whitney U test, 2-way repeated measures analysis of variance, and the Cohen d. RESULTS AND DISCUSSION: Before the intervention, no significant differences were found between groups for any of the variables. Postintervention, significant differences were observed in cognition, conditioning, muscle endurance, and balance. Significant time-by-group interactions were detected in all the intergroup analyses. The improvements observed in the intervention group had medium to large effect sizes (0.35-1.15). The control group's decrease in cognition (13.9%) had a large effect size, while its Functional Reach test decrease (11.4%) had a medium effect size, with no significant change in conditioning or muscle endurance. CONCLUSION: The training program improved cognitive function, muscle endurance, aerobic conditioning, and balance in older adults with MCI.

Objective: to determine the prevalence of body image satisfaction in elderly subjects, as well as its relationship with nutritional status, anthropometric indicators and quality of life. Method: a cross-sectional, descriptive and analytical study was carried out with elderly individuals from Primary Care units (Family Health Strategy) from all the health districts of Porto Alegre, in the state of Rio Grande do Sul. The variables studied were: sociodemographic (gender; age; marital status and schooling), anthropometric (weight; height; body mass index; arm, calf, waist and hip circumference; waist-hip ratio and triceps skinfold), nutritional (Mini Nutritional Assessment), and clinical (quality of life; body image satisfaction). The Stunkard Silhouettes Scale, the Mini Nutritional Assessment and the Flanagan quality of life scale were applied. For data analysis, logistic regression (five steps) was performed with the Conditional Backward method. Results: a total of 532 elderly users (68.96 (7.14) years) were evaluated, mostly women (64.8%) who were dissatisfied with their body image (71.7%). The predictors of body image satisfaction were: eutrophic/underweight body mass index, eutrophy/insufficient arm circumference, and higher mean quality of life scores. Conclusion: in general, a low prevalence of body image satisfaction was identified among the elderly. Subjects with lower body mass index, smaller arm circumference measures and better quality of life had a greater chance of being satisfied with their body image.
Objetivo: determinar a prevalência da satisfação com a imagem corporal em idosos, bem como a sua relação com o estado nutricional, indicadores antropométricos e qualidade de vida. Método: estudo transversal, descritivo e analítico desenvolvido com idosos provenientes de unidades da Estratégia Saúde da Família de todos os distritos sanitários de Porto Alegre/Rio Grande do Sul. As variáveis pesquisadas foram: sociodemográficas (sexo; idade; estado civil e escolaridade), antropométricas (peso; altura; índice da massa corporal; circunferências do braço, panturrilha, cintura e quadril; razão cintura-quadril e dobra cutânea triciptal), nutricional (Mini Avaliação Nutricional), e clínicas (qualidade de vida; satisfação com a imagem corporal). Foram aplicadas a Escala de Silhuetas de Stunkard (imagem corporal), a Mini Avaliação Nutricional e a escala de qualidade de vida de Flanagan. Para análise dos dados foi realizada regressão logística (cinco etapas) com o método Backward condicional. Resultados: foram avaliados 532 usuários idosos [68,96 (7,14) anos], em sua maioria mulheres (64,8%) e insatisfeitas com sua imagem corporal (71,7%). Foram consideradas variáveis preditoras da satisfação com a imagem corporal: índice de massa corporal eutrófico/baixo peso, circunferência do braço eutrofia/insuficiente e média mais alta na qualidade de vida. Conclusão: identificou-se baixa prevalência da satisfação com a imagem corporal entre os idosos em geral. Aqueles com menor índice de massa corporal, menores medidas de circunferência do braço e melhor qualidade de vida apresentaram maiores chances de serem satisfeitos com a sua imagem corporal.

INTRODUCTION: the measurement of the adductor pollicis muscle thickness (APMT) has been investigated as an anthropometric parameter; however, there are few studies related to hospitalized elderly patients. OBJECTIVE: to analyze the association between APMT and nutritional parameters in hospitalized elderly patients. METHOD: cross-sectional study made in 331 hospitalized elderly patients. The following variables have been assessed: APMT, Mini Nutritional Assessment® (MNA®), body mass index (BMI), arm circumference (AC), calf circumference (CC) and handgrip strength (HGS). RESULTS: the mean age was 78.4 ± 9.7 years and 56.8% were women. The women had showed APMT mean values significantly lower than the men (12.67 ± 4.13 mm vs 15.26 ± 4.01 mm), as well as the elderly patients ≥ 80 years old showed APMT values lower than the younger patients (12.62 ± 4.38 mm vs 14.83 ± 3.90 mm). In relation to the APMT classification, the women were more frequently below P5 than the men (89.9% vs 37.1%). In the univariate analysis, the mean values of APMT were significantly lower in the malnourished elderly patients (MNA®), thinness (BMI), AC < 21 cm, CC < 31 and HGS < P5, regardless of gender. In the multivariate analysis, APMT remained as a factor independently associated with all nutritional indicators, even when adjusted to age and gender. CONCLUSION: APMT has associated with all the nutritional parameters investigated, regardless of gender and age, reinforcing its applicability in the nutritional assessment of elderly people.

Human evolution and lifestyle changes caused by the agricultural and industrial revolutions have led to great advances in medicine and increased life expectancy, whilst also profoundly altering the ecological relationships and disease patterns of populations. Studies involving populations that still enjoy a rural way of life and with traits similar to the Paleolithic period reveal them to present a more robust, resistant and diverse gut microbiota, in comparison to highly industrialized civilizations. The human diet has expanded and broadened to include the consumption of high-calorie foods, particularly from animal sources such as game meat and eggs. For some time, authors have been alert to the fact that a modern lifestyle leads to reduced intake of beneficial bacteria, suggesting that nonpathogenic bacteria are being eradicated. Furthermore, therapeutic procedures, including the use of probiotics and prebiotics, have been proposed to lead to recovery of this microbiota, which is altered due to both the ageing process and lifestyle related aspects. Accordingly, this article aims to review the impact of human aging and modern lifestyle on gut microbiota, within an evolutionary, ecological, epidemiological and therapeutic context.

Analisar a adesão aos dez passos para uma alimentação saudável em idosos e sua relação com estado nutricional. Estudo transversal domiciliar, com amostragem representativa. Participaram 7.315 idosos com média de 70,4±7,35 anos. Os passos com maior adesão foram o 4 e o 10 e o com menor adesão foi o 9. A média de passos seguidos foi significativamente maior nas mulheres, em maiores de 80 anos e menor nos com sobrepeso. As mulheres apresentaram maior frequência de adesão aos passos 2, 3, 8 e 10. A média da idade dos idosos que seguiram os passos 3, 4, 5, 8 e 9 foi significativamente maior, enquanto a média do IMC foi significativamente maior nos que não seguiram os passos 2, 5 e 8 e nos que seguiram os passos 6 e 10. Ressalta-se a importância do estabelecimento de políticas públicas que abranjam estratégias para a promoção de hábitos alimentares saudáveis em idosos com vistas ao envelhecimento ativo e bem-sucedido.
The adhesion to the Ten Steps to Healthy Eating for the elderly and its relationship with the nutritional state is provided in current transversal study with a representative sampling of 7,315 elderly people, mean age 70.4±7.35 years. The fourth and tenth steps had the best adhesion; the ninth steps had the least one. Mean number of steps was significantly higher in females, in people over 80. Lowest number was proper to overweight people. Elderly females had the highest adhesion frequency rates for steps 2, 3, 8 and 10. Mean number of elderly people that complied with steps 3, 4, 5, 8 and 9 was significantly higher, whereas mean BMI was significantly higher in those who did not follow Steps 2, 5 and 8 and followed Steps 6 and 10. The establishment of public policies should be underscored. They would comprehend strategies for the promotion of healthy eating habits in the elderly for a healthy and successful aging.
