Association between vitamin B2 intake and cognitive performance among older adults: a cross-sectional study from NHANES

The impact of vitamin B2 (riboflavin) intake on cognitive performance among older adults in the United States (US) remains inadequately understood. This study aimed to explore the association between vitamin B2 intake and cognitive performance among non-institutionalized elderly people in the US. Weighted logistic regression was used to evaluate the association between vitamin B2 intake and cognitive performance. Vitamin B2 intake was determined from the mean of two 24-hour dietary recall interviews. Three cognitive ability assessment tests, namely the Immediate Recall Test (IRT), Animal Fluency Test (AFT), and Digit Symbol Substitution Test (DSST), were performed. Participants included all older adults over 60 who underwent cognitive scoring, with cut-offs defined based on the lowest quartile (25th percentile) for each test (the cut-offs for the three scores were 15.625, 12, and 33, respectively). Sensitivity analysis, including dose-response curves, subgroup analyses, interaction effects, per 1 standard deviation (SD), recommended dietary allowance (RDA), and residual energy model analysis, were performed to solidify the solid association between vitamin B2 and cognitive performance. A total of 2893 individuals aged over 60 were included, with a mean age of 69 (7) years, and 46% were men. There was a significant association between vitamin B2 intake and all three cognitive scores (IRT, Odds Ratio = 0.77, 95% confidence interval: [0.65,0.92]; AFT, 0.75, [0.64,0.88]; DSST, 0.72, [0.59,0.88]). Moreover, vitamin B2 intake above the RDA reduced the risk of low cognitive performance (IRT, 0.66, [0.46,0.93]; AFT, 0.83, [0.62,1.11]; DSST, 0.65, [0.45,0.92]) compared to intake below the RDA. Dose-response curves indicated that higher vitamin B2 intake was negatively associated with the risk of low cognitive performance. Physical activity may modify the association between vitamin B2 and cognitive performance. Vitamin B2 intake was positively associated with cognitive performance among older adults. Adequate vitamin B2 intake could help protect cognitive function.

Oral health conditions and cognitive and nutritional profile in non-institutionalized elderly in the North of Minas Gerais

The aim of this study was to evaluate oral health and its relationship with sociodemographic aspects and the cognitive and nutritional profile of non-institutionalized elderly people treated at a reference center in the North of Minas Gerais. This is a cross-sectional, documentary and quantitative study, based on an analysis of 1026 medical and dental records, between 2008 and 2011, of patients aged 60 or over. The instruments used included the Minimental, Clinical Dementia Scale, mini nutritional assessment and oral health assessment. The existence of edentulism and the use of dentures were compared with sociodemographic data and the cognitive and nutritional profile, using binary logistic regression (p<0.05). The presence of edentulism was significantly more likely to occur in elderly females (p=0.036, OR: 1.857, CI: 1.042-3.306). In relation to the use of dental prostheses, the chance of occurrence was increased in elderly women (p=0.001, OR: 1.807), people aged between 75 and 84 years (p=0.028, OR: 1.752), illiterate (p= 0.014, OR: 1.584), underweight (p=0.017, OR: 0.585), and with cognitive impairment (p=0.012, OR: 1.581). We conclude that edentulism affects more elderly women; and the use of dental prostheses occurs more in elderly women, between 74 and 84 years old, illiterate, underweight, and with cognitive impairment.

Frailty prevalence in 42 European countries by age and gender: development of the SHARE Frailty Atlas for Europe

Comparative frailty prevalence data across European countries is sparse due to heterogeneous measurement methods. The Survey of Health, Ageing and Retirement (SHARE) initiative conducted interviews with probability sampling of non-institutionalized elderly people in several European countries. Previous frailty analyses of SHARE datasets were limited to initial SHARE countries and did not provide age- and gender-stratified frailty prevalence. Our aim was to provide age- and gender-stratified frailty prevalence estimates in all European countries, with predictions where necessary. From 29 SHARE participating countries, 311,915 individual surveys were analyzed. Frailty prevalence was estimated by country and gender in 5-year age bands using the SHARE Frailty Instrument and a frailty index. Association of frailty prevalence with age, gender, and GDP per capita (country-specific economic indicator for predictions) was investigated in multivariate mixed logistic regression models with or without multiple imputation. Female gender and increasing age were significantly associated with higher frailty prevalence. Higher GDP per capita, with or without purchasing power parity adjustment, was significantly associated with lower frailty prevalence in the 65–79 age groups in all analyses. Observed and predicted data on frailty rates by country are provided in the interactive SHARE Frailty Atlas for Europe. Our study provides age- and gender-stratified frailty prevalence estimates for all European countries, revealing remarkable between-country heterogeneity. Higher frailty prevalence is strongly associated with lower GDP per capita, underlining the importance of investigating transferability of evidence across countries at different developmental levels and calling for improved policies to reduce inequity in risk of developing frailty across European countries.

Factors associated with inequalities in social conditions in the health of elderly white, brown and black people in the city of São Paulo, Brazil

The scope of this study is to identify determining factors of disparities in social conditions in the health of non-institutionalized elderly people in the city of São Paulo, from the standpoint of self-declaration of skin color. It is a cross-sectional study with a representative sample of 1,017 elderly participants in the "2015 Health Survey of the Municipality of São Paulo". The analysis used crude and adjusted Poisson regression models, reporting the prevalence ratio and 95% confidence intervals as a measure of association between the variables. In the adjusted analysis, brown and black skin color was positively associated with worse schooling, negative self-assessment of health status, health insurance and access to public health services. On the one hand, black skin color was no longer associated with the lowest income, however, it was associated with arterial hypertension. On the other hand, brown skin color was associated with low income, but not with arterial hypertension. Elderly black and brown people had worse health conditions, less access to private health services and socioeconomic resources. These results are compatible with the hypothesis of structural racism in São Paulo's society and may inform social health policies aimed at promoting health and social justice.

Applicability of the sarc-f questionnaire by telephone interview

Rationale: Sarcopenia is a muscle disorder associated with aging. For early detection of this condition, the European Working Group on Sarcopenia in Older People (EWGSOP) recommends using the SARC-F questionnaire as a screening tool. The objective of this study is to evaluate the applicability of the SARC-F questionnaire, by telephone interview, to non-institutionalized elderly people belonging to a cohort in southern Brazil.

Nutrition and Healthy Aging: Prevention and Treatment of Gastrointestinal Diseases.

Nutritional well-being is a fundamental aspect for the health, autonomy and, therefore, the quality of life of all people, but especially of the elderly. It is estimated that at least half of non-institutionalized elderly people need nutritional intervention to improve their health and that 85% have one or more chronic diseases that could improve with correct nutrition. Although prevalence estimates are highly variable, depending on the population considered and the tool used for its assessment, malnutrition in the elderly has been reported up to 50%. Older patients are particularly at risk of malnutrition, due to multiple etiopathogenetic factors which can lead to a reduction or utilization in the intake of nutrients, a progressive loss of functional autonomy with dependence on food, and psychological problems related to economic or social isolation, e.g., linked to poverty or loneliness. Changes in the aging gut involve the mechanical disintegration of food, gastrointestinal motor function, food transit, intestinal wall function, and chemical digestion of food. These alterations progressively lead to the reduced ability to supply the body with adequate levels of nutrients, with the consequent development of malnutrition. Furthermore, studies have shown that the quality of life is impaired both in gastrointestinal diseases, but especially in malnutrition. A better understanding of the pathophysiology of malnutrition in elderly people is necessary to promote the knowledge of age-related changes in appetite, food intake, homeostasis, and body composition in order to better develop effective prevention and intervention strategies to achieve healthy aging.

Impact of Different Aquatic Exercise Programs on Body Composition, Functional Fitness and Cognitive Function of Non-Institutionalized Elderly Adults: A Randomized Controlled Trial.

Aquatic physical exercise programs have become progressively more popular among elderly people. Some of the major physical exercise program disadvantages on land are minimized due to the specific properties of the aquatic environment. The purpose of the present randomized controlled study is to verify the effects of different aquatic physical exercise programs on body composition, functional fitness and cognitive function in non-institutionalized elderly people. For this study, 102 elderly individuals were randomly allocated into four different groups: AerG (n = 25, 71.44 ± 4.84 years); IntG (n = 28, 72.64 ± 5.22 years); ComG (n = 29, 71.90 ± 5.67 years) and CG (n = 20, 73.60 ± 5.25 years). Individuals from the groups AerG, IntG and ComG participated in three different aquatic physical exercise programs for a period of 28 weeks. The CG participants kept to their usual routines. All participants were evaluated for body composition, functional fitness and cognitive function at two time moments, i.e., pre- (M1) and post-intervention (M2). Significant differences for body composition were found between M1 and M2 for FM (p < 0.001), LBM (p < 0.001) and WCir (p < 0.01) in the AerG, for BMI (p < 0.05), FM (p < 0.05), LBM (p < 0.001) and LCir-R (p < 0.05) in the IntG, and for WGT (p < 0.01), FM (p < 0.05), LBM (p < 0.01), LCir-R (p < 0.05) and LCir-L (p < 0.01) in the ComG groups. For functional fitness, differences were found between M1 and M2 for 2m-ST (p < 0.000), 30s-CS (p < 0.000), 30s-AC (p < 0.05), HG-T-R (p < 0.000) and HG-T-L (p < 0.000) in the AerG, for 2m-ST (p < 0.05), BS-R (p < 0.05), 30s-CS (p < 0.000), 30s-AC(p < 0.01), HG-T-R (p < 0.000) and HG-T-L (p < 0.000) in the IntG, and for 30s-CS (p < 0.000), HG-T-R (p < 0.000) and HG-T-L (p < 0.000) in the ComG groups. The present study evidenced the beneficial effects of physical exercise in an aquatic environment on body composition, functional fitness and cognitive function in non-institutionalized elderly adults. The ComG water-based exercise program showed more beneficial effects in the improvement of body composition and cognitive function variables, while the IntG and AerG programs were more effective in the improvement of functional fitness.

Considerações finais: Visto o exposto, podemos concluir que os principais fatores de risco associados a risco de quedas de idosos, institucionalizados e não institucionalizados, mencionados nos estudos selecionados formam a necessidade de algum tipo de auxílio para se deslocar, fraqueza, equilíbrio, distúrbios de marcha, transtornos de mobilidade e controle postural, sexo feminino, idade avançada, cor da pele, dificuldades para enxergar, ambientes inadequados e comorbidades associadas.

The Relationship between Frailty, Obesity and Social Deprivation in Non-Institutionalized Elderly People.

With the increasing prevalence of obesity and the risk of increased dependency among the elderly, it becomes important to characterize the link between obesity and frailty. The relationship between obesity and social deprivation would be bidirectional, with each influencing the other. Main objective was to study the relationship between frailty as defined by Fried and obesity (Body Mass Index (BMI) and abdominal obesity). Secondary objective was to assess the relationship between frailty and social deprivation. This was a cross-sectional study, with data collected between January 2014 and December 2015 using a senior periodic health prevention examination form used in the 4 sites of the health examination center, in Rhone, among non-institutionalized seniors (≥ 65 years). Frailty was defined according to Fried's criteria. Obesity was defined by a BMI ≥ 30 kg / m2 and a waist circumference > 88 cm for women and >102 cm for men. We studied the association between obesity according to BMI ≥ 30kg / m2 on the one hand and abdominal obesity on the other hand with frailty according to Fried. The analyzes were adjusted for gender, age, education level, not being in a relationship and social deprivation quantified by the assessment score of deprivation and health inequalities (EPICES score). 1593 senior health prevention examination forms were studied. According to BMI, senior women were almost twice as likely to be frail when obese (RR = 1.92, 95% CI [1.06 - 3.45], p = 0.018). The results were similar for abdominal obesity in women aged 65-74 years (RR = 2.12, 95% CI [1.03-4.35], p = 0.029). There was no relationship in men for both types of obesity. Seniors who were socially deprived were 2.7 times more likely to be frail than non-deprived seniors (adjusted RR = 2.76, 95% CI [1.808 - 4.203], p <0.001). Obesity (BMI ≥ 30kg / m2 and high waist circumference) was associated with increased frailty among older, non-institutionalized women who came for a periodic health prevention examination. Screening and prevention of obesity in the elderly appears to be a major public health issue, and remains a priority target for action.

Cross-Cultural Examination of University Education and Ego Integrity in Late Adulthood: Implications for Policy and Practice

ABSTRACT Studies on education generally find that higher education has a positive impact on various aspects of life. Nevertheless, studies focused on elderly people and their psychosocial health and development seldom view higher education as an important factor. Our aim was to explore the relation between higher education and ego integrity, a measure based on Erikson’s concept of psychological maturity in later life. We used four national samples of non-institutionalized elderly people from Cameroon (N = 238), China (N = 254), Czech Republic (N = 167), and Germany (N = 240). Relationships between ego integrity and several possible moderator variables were tested by multivariate regressions in each sample. Between-subject ANOVA was employed to test differences in ego integrity between university educated and non-university educated people. We found that ego integrity is affected by culture in interaction with gender and the level of education attained. University-educated people reported higher ego integrity than persons with lower education in three of four cultural samples, which suggests a relatively stable relationship between university education and ego integrity when controlling for gender, age, and working status. These findings highlight the importance of education in late adulthood. In terms of policies and practice, they underscore the importance of reduction of educational inequalities as well as desirability of improved access to higher education, expansion of opportunities for the achievement of complete education in later life, and facilitation and support of lifelong learning.

Farmacoepidemiologia e o uso de medicamentos potencialmente inapropriados em idosos institucionalizados e não institucionalizados

Pharmacoepidemiology is a field of study that connects two broad areas: clinical pharmacology, which studies the effects of drugs on humans, and an epidemiology, which studies a distribution and determinants of disease in the population. This study aimed to verify the prevalence of potentially inappropriate drugs in institutionalized and non-institutionalized elderly people, both in the city of Sinop-MT, as well as to describe socio-demographic characteristics, family arrangements, drug use and comorbidities. The sample consisted of 40 elderly people, 26 from a community day center and 14 from the Long Stay Institute (LSI), thus constituting two groups. The results of the study showed that polypharmacy is high among the elderly, and among these polypharmacy Potentially Inappropriate Use Medications (PIM) were detected. With regard to the concomitant diseases, many report epigastralgia, but it is a question of being investigated, since the use of medications induces the use of more and more medications itself. In addition, the drugs are equally distributed among adults and the elderly, and there are physiological modifications in a geriatric individual that lead to drug interactions and/or adverse reactions.

Desarrollo de un Taller de risaterapia con un grupo de personas mayores

Introduction: Elderly people constitute an age group that requires special care. With this aim in mind, it has become necessary to implement activities to promote active aging and psychosocial wellbeing. Objective: This procedure researches the benefits of taking part in a laughter therapy workshop for an elderly group of people based on their experience. Methodology: This is a qualitative study conducted via the semi-structured interviewing of 57 non-institutionalized elderly people, of ages ranging from 60 to 88, members of three day centers for the elderly from the Salamanca Social Services Territorial Management Department (Junta de Castilla y Leon). The laughter therapy workshop was conducted in four 3-hour weekly sessions. Results: The analysis of the contents of the participants' discourses revealed categories related to personal growth, state of mind or mood improvement, laughter therapy assessment considering it a physical and a recreational activity, motivation enhancement and the strengthening of interpersonal relations. Conclusions: Results show the positive effects of the laughter therapy workshops on elderly people's psychological and subjective well-being.

Risk of Malnutrition Evaluated by Mini Nutritional Assessment and Sarcopenia in Noninstitutionalized Elderly People.

Malnutrition indices and muscle mass and strength in the elderly are poorly investigated. Moreover, malnutrition seems to be 1 of the more important factors in the cause of sarcopenia. The presence of sarcopenia and its relationship with malnutrition indices were studied in noninstitutionalized elderly people who underwent Comprehensive Geriatric Assessment (CGA). A total of 473 elderly subjects (mean age, 80.9 ± 6.6 years) admitted to CGA were studied. Malnutrition risk was evaluated with Mini Nutritional Assessment (MNA) score, whereas muscle mass and muscle strength were evaluated by bioimpedentiometry and hand grip, respectively. Sarcopenia was assessed as indicated in the European Working Group on Sarcopenia in Older People (EWGSOP) consensus. Overall prevalence of sarcopenia was 13.1%, and it increased from 6.1% to 31.4% as MNA decreased (P < .001). MNA score was lower in elderly subjects with sarcopenia (15.4 ± 4.2) than without sarcopenia (22.0 ± 4.0) (P = .024). Linear regression analysis showed that MNA score is linearly related both with muscle mass (r = 0.72; P < .001) and strength (r = 0.42; P < .001). Multivariate analysis, adjusted for several confounding variables including comorbidity and disability, confirmed these results. MNA score is low in noninstitutionalized elderly subjects with sarcopenia, and it is linearly related to muscle mass and muscle strength. These data indicate that MNA score, when evaluated with muscle mass and strength, may recognize elderly subjects with sarcopenia.

Influence of oral health on the quality of life of institutionalized and noninstitutionalized elderly people

This study aimed to determine the perception of institutionalized (G1) and noninstitutionalized (G2) elderly people on oral health and quality of life (QOL). This cross-sectional, exploratory study applied two instruments - the Geriatric Oral Health Assessment Index (GOHAI) and the World Health Organization QOL-Bref (WHOQOL-BREF) - in two cities of the state of Sao Paulo, Brazil. Among the institutionalized elderly, G1 (n = 150), 50% were not mentally able to answer the questions correctly, 12% did not answer all the questions, and 7.34% refused to take part in the research or were too frail or dependent, resulting in 31 institutionalized participants. In the noninstitutionalized group, G2 (n = 80), 52.50% refused to take part in the research, resulting in 38 noninstitutionalized participants. The elderly individuals (i) who did not respond to three or more questions of the GOHAI, (ii) those who did not answer all the questions of the WHOQOL-Bref, and (iii) those who did not consent to participate in the research study were excluded from the study population (P < 0.05 consider significant). The oral health of both groups minimally affected the QOL of the elderly. The WHOQOL-Bref score varied between the two study groups mainly in terms of physical domain and self-perception of QOL. The study groups showed differences in some variables: self-perception of QOL (P = 0.0209), mobility (P = 0.0057), and access to health services (P = 0.0252). G2 presented the best conditions. The oral health condition of both groups minimally affected the QOL of the participants; however, differences in the self-perception of QOL were significant, mainly in the physical domain.

Frailty, body composition and nutritional status in non-institutionalised elderly

ObjectiveFrailty is a clinical syndrome characterised, among other signs, by involuntary weight loss and decreased muscle strength. The aim of this study was to analyse associations between frailty, body composition and nutritional status in non-institutionalised elderly people in the municipality of Alfândega (Braganza-Portugal). MethodObservational, prevalence and association study involving 220 elderly (mean 75.8±6.8 years of age; 68.8% women). Frailty was assessed according to Fried criteria, body composition by bioelectrical impedance analysis and nutritional status using the Mini Nutritional Assessment Short-Form. ResultsThe prevalence of frailty was 23.6%. Frail participants had, on average, lower total muscle mass and lower segmental muscle mass (arms and legs) than pre-frail and non-frail (p<0.001). From the elderly at risk of malnutrition or undernourished (n=24), the majority (n=13) had frailty syndrome. It was observed that 41.2% of the elderly with low weight were frail. This syndrome prevailed only in 17.1% of the eutrophic persons, increasing again to 22.4% in the overweight group (p<0.001). ConclusionThe phenotypic profile of frail elderly was characterised by lower muscle mass. The results of our study suggest that both underweight and overweight may be associated with frailty. There is the need to prevent and manage frailty, not only taking into account possible treatable medical causes, but also by intervening in important pillars, such as physical activity, dietary and nutritional problems.

Factors associated with Chronic Obstructive Pulmonary Disease among the elderly.

This study aimed to identify factors associated with Chronic Obstructive Pulmonary Disease (COPD) among non-institutionalized elderly people. It involved a cross-sectional study conducted on the basis of a household survey, followed by spirometry. People diagnosed with COPD were compared with those with normal spirometry, through bivariate analysis, followed by multivariate regression analysis. We identified 53 elderly people were identified with COPD. After multivariate analysis, the following factors associated with COPD were identified: past or current smoking (OR: 3.74; 95% CI: 1.65-8.46), presence of chronic sputum (OR: 4.92; 95% CI: 2.03-11.95), pulse oximetry at rest ≤ 90% (OR: 8.74; 95%CI: 1.27-60.07), self-reported asthma (OR: 3.41; 95% CI: 1.01-11.57). The results reveal associated factors that highlight the need to review the selection criteria for patients at risk of COPD among the elderly.

Qualidade subjetiva do sono, sintomas depressivos, sentimentos de solidão e institucionalização em pessoas idosas

Objetivos: A presente investigação teve como principais objetivos descrever a qualidade subjetiva do sono e as perturbações do sono e analisar a intensidade dos sintomas depressivos e dos sentimentos de solidão em idosos institucionalizados; comparar estes dados com um grupo de idosos não institucionalizados e analisar a relação entre estas variáveis nos dois grupos.Métodos: Este estudo insere-se no Projeto Trajetórias do Envelhecimento de Idosos em Resposta Social de onde foi retirada uma amostra de cento e quarenta idosos sem défice cognitivo, com 70 institucionalizados e 70 não institucionalizados emparelhados por idade, sexo, escolaridade e estado civil. A média de idades foi de 76,58 (DP = 6,10), incluindo 104 mulheres e 36 homens. Como instrumentos foram utilizados um Questionário Sociodemográfico, o Questionário sobre o Sono na Terceira Idade, a Escala Geriátrica de depressão e a Escala de Solidão da Universidade da Califórnia, Los Angeles.Resultados: Verificou-se que os idosos institucionalizados apresentavam mais sentimentos de solidão do que os não institucionalizados. Contudo, não se verificaram diferenças entre os dois grupos em relação aos sintomas depressivos, qualidade subjetiva do sono ou perturbações do sono, com algumas exceções: os idosos residentes na comunidade mostraram ter a perceção de demorar mais tempo a adormecer, de acordar mais cedo e de ter mais pesadelos. Através de uma análise correlacional verificou-se, na amostra global, que quanto pior a qualidade subjetiva do sono mais sintomas depressivos se observavam e quanto mais sintomas depressivos, mais sentimentos de solidão, não havendo, contudo, relação entre o sono e a solidão.Conclusões: Concluímos que a situação de institucionalização se acompanha de mais sentimentos de solidão, mas não de sintomas depressivos ou de pior qualidade de sono. Por esse motivo, sugere-se que se desenvolvam programas de intervenção dirigidos à solidão em idosos institucionalizados.

Tinetti mobility test is related to muscle mass and strength in non-institutionalized elderly people.

Elderly people are characterized by a high prevalence of falls and sarcopenia. However, the relationship among Tinetti mobility test (TMT) score, a powerful tool to detect elderly people at risk of falls, and sarcopenia is still not thoroughly investigated. Thus, to determine the relationship between TMT score and muscle mass and strength, 337 elderly participants (mean age 77.1 ± 6.9years) admitted to comprehensive geriatric assessment were enrolled. TMT score, muscle mass by bioimpedentiometer, and muscle strength by grip strength were evaluated. Muscle mass progressively decreased as TMT score decreased (from 15.3 ± 3.7 to 8.8 ± 1.8kg/m2; p for trend <0.001). Similarly, muscle strength decreased progressively as Tinetti score decreased (from 34.7 ± 8.0 to 23.7 ± 8.7kg; p for trend 0.001). Linear regression analysis demonstrated that TMT score is linearly related with muscle mass (y = 4.5x + 0.4, r = 0.61; p < 0.01) and strength (y = 14.0x + 0.8, r = 0.53; p < 0.01). Multivariate analysis confirms the strong relationship between the TMT score and muscle mass (r = 0.48, p = 0.024) and strength (r = 0.39, p = 0.046). The present study indicates that TMT score is significantly related to muscle mass and strength in non-institutionalized elderly participants. This evidence suggests that TMT score, together with evaluation of muscle mass and strength, may identify sarcopenic elderly participants at high risk of falls.
