Habitual physical activity and sedentary behavior as predictors of dynapenia in older adults: a cross-sectional study

ABSTRACT BACKGROUND: Dynapenia is a risk factor of mortality. Therefore, the development of low-cost and easy-to-apply tools is essential to optimize the health surveillance actions of older people. OBJECTIVES: To compare the time spent on habitual physical activity (HPA) and sedentary behavior (SB) among dynapenic and non-dynapenic older adults and ascertain the predictive ability of these behaviors on outcome. DESIGN AND SETTING: A cross-sectional population epidemiological survey was conducted involving 208 older adults. METHODS: HPA and SB were quantified using the International Physical Activity Questionnaire, and dynapenia was identified by handgrip strength (women: 18.37 kgf; men: 26.75 kgf). RESULTS: The prevalence was 24.50%. In both sexes, dynapenic individuals reported a HPA median time of 70.00 minutes/week (min/wk), while non-dynapenic women and men reported HPA median times of 240.00 and 280.00 min/wk, respectively (P < 0.05). For SB among dynapenic individuals, a median of 388.75 min/day was observed in women and 428.57 min/d in men. In contrast, non-dynapenic women and men had 291.42 and 274.28 min/day in SB (P < 0.05), respectively. The best cutoff HPA to discriminate the outcome was 150.00 min/wk in women (sensitivity: 73.30%; specificity: 60.67%) and 140.00 min/wk in men (sensitivity, 71.43%; specificity, 61.54%). The best cutoff SB was 381.43 min/day in women (sensitivity, 53.30%; specificity, 84.80%) and 351.43 min/day in men (sensitivity, 71.43%; specificity, 73.85%). CONCLUSION: Older individuals with dynapenia spent less time on HPA and more time in SB. Furthermore, HPA was found to be a better discriminator of dynapenic individuals, and SB better discriminated non-dynapenic individuals.

RESUMO Objetivo Investigar a prevalência e os fatores associados à suspeição de transtornos mentais comuns (TMCs) em idosos de um município de pequeno porte do Nordeste brasileiro. Métodos Estudo epidemiológico populacional, com delineamento transversal, realizado com idosos da área urbana de Aiquara-BA. As informações sociodemográficas, de hábitos de vida e de condições de saúde foram coletadas, em entrevistas, a partir de um instrumento próprio. O nível de atividade física foi averiguado por meio do International Physical Activity Questionnaire. Foram considerados insuficientemente ativos os entrevistados que despendiam tempo < 150 mim/sem em atividade física. A identificação da suspeição de TMCs foi realizada pelo Self-Reporting Questionnaire, com ponto de corte de sete ou mais respostas positivas. Para as análises inferenciais, utilizou-se o teste qui-quadrado de Pearson, regressão logística multivariada e seus respectivos intervalos de confiança (ICs) de 95,0% (p ≤ 0,05). Resultados Participaram do estudo 232 idosos (58,6% mulheres), com média de idade de 71,6 ± 7,5 anos e prevalência de suspeição de TMCs de 32,6%. No modelo final de regressão, foi observado que estiveram associadas à suspeição de TMCs: as mulheres (RP: 2,49; IC95%: 1,27-4,88); os idosos com autopercepção negativa de saúde (RP: 2,73; IC95%: 1,46-5,10); os idosos que referiram ter distúrbios do sono (RP: 3,12; IC95%: 1,56-6,21); e os insuficientemente ativos (RP: 2,30; IC95%: 1,20-4,41). Conclusão Em Aiquara-BA, identificou-se elevada prevalência de suspeição de TMCs, principalmente em mulheres, nos avaliados com autopercepção de saúde negativa, entre os que referiram ter distúrbios do sono e nos participantes insuficientemente ativos.

ABSTRACT Objective To investigate the prevalence and factors associated with suspected common mental disorders (CMD) in older adults in a small municipality in Northeastern Brazil. Methods Population epidemiological cross-sectional study carried out with older adults from the urban area of Aiquara, BA. Sociodemographic information, lifestyle and health conditions were collected in interviews, using a specific instrument. The level of physical activity was assessed using the International Physical Activity Questionnaire. Respondents who dismissed time < 150 min/wk in physical activity were considered insufficiently active. The identification of suspected CMD was performed using the Self-Reporting Questionnaire, with a cut-off point of seven or more positive responses. For inferential analyses, Pearson's chi-square test and multivariate logistic regression were used, and their respective 95% confidence intervals (CIs) (p ≤ 0.05). Results A total of 232 older adults (58.6% women), with a mean age of 71.6 ± 7.5 years participated in the study and 32.6% exhibited suspected CMD. In the final regression model, it was observed that women were associated with suspected CMD (PR: 2.49; 95% CI: 1.27-4.88); older adults with self-perceived poor health (PR: 2.73; 95%CI: 1.46-5.10); the older adults who reported experiencing sleep disorders (PR: 3.12; 95%CI: 1.56-6.21) and those who were insufficiently active (PR: 2.30; 95%CI: 1.20-4.41). Conclusion In Aiquara, BA, a high prevalence of suspected common mental disorders was identified, especially in women, in patients evaluated with negative self-perceived health, among those who reported having sleep disorders and in insufficiently active participants.

Functional performance indicators associated with hypertension in older people / Indicadores de desempenho funcional associados à hipertensão em pessoas idosas

Abstract Introduction During aging, changes occur in the human body that increase the probability of arterial hypertension which can potentiate deleterious effects on functional performance. Objective To analyze the association of functional performance indicators with hypertension in older people. Methods An epidemiological, population-based, cross-sectional survey was conducted with 209 older adults (58.40% women). Functional performance was assessed by the following tests: handgrip strength; chair stand test; arm curl test; timed up and go (TUG); sit and reach test; and step in place test (SPT). Diagnosis of arterial hypertension was self-reported. Results The prevalence of hypertension was found to be 58.90% (males: 51.70%; females: 63.90%). It was also observed that the hypertensive individuals of both sexes had worse performance in SPT and TUG (p < 0.05). Furthermore, it was found that each additional second for TUG increased by 11% the probability of hypertension in men (PR:1.11; 95%CI: 1.03-1.20) and by 7% in women (PR: 1.07; 95%CI: 1.04-1.12), while each step performed in the SPT decreased the probability for the outcome by 2% (men and women = PR: 0.98; 95%CI: 0.97-0.99). Conclusion TUG was found to be positively associated with hypertension, while SPT was inversely associated with hypertension.

Resumo Introdução Durante o envelhecimento ocorrem modificações no corpo humano, as quais aumentam a probabilidade de hipertensão arterial sistêmica (HAS),o que pode potencializar efeitos deletérios no desem-penho funcional. Objetivo Analisar a associação de indicadores de desempenho funcional com a HAS em pessoas idosas. Métodos Inquérito epidemiológico, populacional, transversal, conduzido com 209 idosos (58,40% mulheres). O desempenho funcional foi averi-guado pelos seguintes testes: força de preensão manual; levantar e sentar da cadeira; flexão do antebraço; levantar, caminhar e sentar (LCS); sentar e alcançar o pé; e marcha estacionária (ME). O diagnóstico da HAS foi autorreferido. Resultados Averiguou-se a prevalência de HAS em 58,9% dos participantes (homens: 51,7%; mulheres: 63,9%). Observou-se, também, que os hipertensos de ambos os sexos apresentaram pior desempenho na ME e LCS (p < 0,05). Além disso, verificou-se que cada segundo a mais despendido para LSC aumentou em 11% e 7%, respectivamente, a probabilidade de HAS nos homens (RP: 1,11; IC95%: 1,03-1,20) e nas mulheres (RP: 1,07; IC95%: 1,04-1,12), enquanto cada passo a mais realizado na ME diminuiu em 2% a probabilidade para o desfecho (homens e mulheres = RP: 0,98; IC95%: 0,97-0,99). Conclusão Identificou-se que o teste de LCS esteve positivamente associado à HAS. Ademais, a ME apresentou-se inversamente associada à HAS.

Anthropometric indicators of adiposity as predictors of systemic arterial hypertension in older people: a cross-sectional analysis / Indicadores antropométricos de adiposidade como preditores de hipertensão arterial sistêmica em pessoas idosas: uma análise transversal

ABSTRACT Objective: To analyze the association of anthropometric indicators of adiposity in older people, according to sex, with hypertension; to compare the scores of these variables between participants with and without hypertension; and to identify among them those with better predictive ability for screening the outcome. Methods: Epidemiological, population-based, cross-sectional study conducted with 210 older people. The anthropometric indicators analyzed were: body mass index, waist circumference, abdominal circumference, body adiposity index, triceps skinfold, waist-to-hip ratio, waist-to-height ratio, and conicity index. Hypertension diagnosis was self-reported. Results: The indicators of adiposity increased the probability of hypertension. Additionally, hypertensive older people of both sexes showed higher scores on adiposity indicators than non-hypertensive subjects (p < 0.05). For men, the most sensitive indicator for the outcome was conicity index (81.82%; cut-off point: 1.30) and the most specific was body mass index (69.77%; cut-off point: 25.05 kg/m2). For women, the most sensitive indicator for the outcome was the body adiposity index (86.08%; cut-off point: 31.03%), and the most specific was the abdominal circumference (82.82%; cut-off point: 98.70 cm). Conclusion: In both sexes, the indicators of adiposity were positively associated with hypertension; hypertensive participants showed higher values in the scores of the indicators. Additionally, the body adiposity index (women) and conicity index (men) demonstrated greater ability to screen for hypertension, while the abdominal circumference and body mass index demonstrated greater ability to screen for non-hypertensive women and men, respectively.

RESUMO Objetivo: Analisar a associação de indicadores antropométricos de adiposidade com a hipertensão, em pessoas idosas, de acordo com o sexo; comparar os escores dessas variáveis entre os participantes com e sem hipertensão; e identificar os indicadores com melhor capacidade preditiva à triagem do desfecho. Métodos: Estudo epidemiológico, populacional, transversal, realizado com 210 pessoas idosas. Os indicadores antropométricos analisados foram: índice de massa corporal, circunferência da cintura, circunferência abdominal, índice de adiposidade corporal, dobra cutânea tricipital, relação cintura/quadril, relação cintura/altura e índice de conicidade. O diagnóstico de hipertensão arterial foi autorreferido. Resultados: Observou-se que os indicadores de adiposidade aumentaram a probabilidade à hipertensão. Além disso, as pessoas idosas hipertensas, de ambos os sexos, apresentaram maiores escores nos indicadores de adiposidade quando comparadas às não hipertensas (p < 0,05). Para os homens, o indicador mais sensível ao desfecho foi o índice de conicidade (81,82%; ponto de corte: 1,30) e o mais específico foi o índice de massa corporal (69,77%; ponto de corte: 25,05 kg/m2). Nas mulheres, o indicador mais sensível ao desfecho foi o índice de adiposidade corporal (86,08%; ponto de corte: 31,03%) e o mais específico foi a circunferência abdominal (82,82%; ponto de corte: 98,70 cm). Conclusão: Em ambos os sexos, os indicadores de adiposidade mostraram-se positivamente associados à hipertensão; os participantes hipertensos apresentaram valores mais elevados nos escores dos indicadores. Ademais, identificou-se para os sexos, feminino e masculino, que os indicadores com melhor capacidade de rastrear a hipertensão, foram, respectivamente, o índice de adiposidade corporal e índice de conicidade. Enquanto a circunferência abdominal e o índice de massa corporal mostraram maior capacidade de rastrear, respectivamente, as mulheres e os homens não hipertensos.

Physical fitness according to the level of physical activity in older people: a cross-sectional analysis / Aptidão física de acordo com o nível de atividade física em pessoas idosas: uma análise transversal

Abstract Introduction Aging is marked by physiological changes and a decrease in physical activity. These aspects can have repercussions, namely declining functionality and increasing likelihood of adverse events. Objective To compare performance in physical fitness tests of sufficiently and insufficiently active older people. Methods Epidemiological population study, cross-sectional, carried out with 209 older people (58.4% women) from Aiquara/BA. Sociodemographic information was obtained by means of interviews. Physical fitness was measured by means of the following tests: handgrip strength, chair stand, arm curl, timed up and go, sit and reach and step in place. The level of physical activity was checked by the International Physical Activity Questionnaire (<150 min/week physical activity = insufficiently active). Comparisons were made using the Student t-test or Mann-Whitney U-test, according to the distribution of normality determined by the Kolmogorov-Smirnov test (p ≤ 0.05). Results We found that 51.70% of the participants were insufficiently active (men: 66.66%; women: 40.98%). In addition, insufficiently active participants of both sexes performed less well in the handgrip strength, chair stand, arm curl, timed up and go and step in place tests (p < 0.05). Moreover, insufficiently active men showed lower performance in the sit and reach test than sufficiently active men (p < 0.05). Conclusion Insufficiently active older women and men have lower muscle strength/resistance, dynamic balance/agility and cardiorespiratory endurance. Furthermore, insufficiently active men show less flexibility than those sufficiently active.

Resumo Introdução O envelhecimento é marcado por alterações fisiológicas e diminuição do tempo em atividade física (AF). Tais aspectos podem repercutir no declínio da funcionalidade e propiciar maior probabilidade para eventos adversos. Objetivo Comparar o desempenho em testes de aptidão física de pessoa idosas suficiente e insuficientemente ativas. Métodos Estudo epidemiológico populacional, transversal, realizado com 209 pessoas idosas (58,40% mulheres) de Aiquara/BA. As informações sociodemográficas foram obtidas a partir de entrevistas. A aptidão física foi mensurada por meio dos seguintes testes: força de preensão manual; levantar e sentar da cadeira; flexão do antebraço; levantar, caminhar 2,44 m e sentar; sentar e alcançar o pé; e marcha estacionária. O nível de atividade física foi averiguado pelo International Physical Activity Questionnaire (< 150 min/sem em AF = insuficientemente ativo). As comparações foram feitas por meio dos testes t de Student ou U de Mann-Whitney, conforme a distribuição de normalidade averiguada pelo teste de Kolmogorov-Smirnov (p ≤ 0,05). Resultados A prevalência do nível de AF insuficiente foi de 51,70% (homens: 66,66%; mulheres: 40,98%). Verificou-se, em ambos os sexos, que os insuficientemente ativos demonstraram menor desempenho na força de preensão manual; sentar e levantar da cadeira; flexão do antebraço; levantar, caminhar e sentar; e marcha estacionária (p < 0,05). Além do mais, os homens insuficientemente ativos apresentaram menor desempenho no teste sentar e alcançar o pé em relação aos suficientemente ativos (p < 0,05). Conclusão Identificou-se que os idosos insuficientemente ativos, de ambos os sexos, apresentaram menor força/resistência muscular, equilíbrio dinâmico/agilidade e resistência cardiorrespiratória. Ademais, os homens insuficientemente ativos demonstraram menor flexibilidade do que os suficientemente ativos.

Association of physical activity combined with sedentary behavior with dynapenia in older adults / Associação da atividade física combinada ao comportamento sendentário com a dinapenia em idosos

ABSTRACT This research aimed to analyze the association of physical activity (PA) level combined with exposure to sedentary behavior (SB) with dynapenia in older people. Epidemiological, cross-sectional study, conducted with 208 older adults in Aiquara, Bahia, Brazil. Habitual PA and SB were quantified using the International Physical Activity Questionnaire. Based on this information, participants were divided into groups (G): G1) sufficiently active and low SB; G2) sufficiently active and high SB; G3) insufficiently active and low SB; and G4) insufficiently active and high SB. Assessment of dynapenia was performed based on the values of the handgrip strength measured in kilogram-force (kgf) (women: 18.37 kgf; men: 26.75 kgf). Descriptive analysis was conducted using absolute and relative frequencies, mean and standard deviation. For the inferential analysis, Poisson regression was used, with a robust estimator, calculation of Prevalence Ratios (PRs) and their relevant Confidence Intervals (CIs) of 95.0%. It was observed that the mean age of women and men were, respectively, 71.0 ± 6.7 and 72.3 ± 8.1 years and the prevalence of dynapenia observed was about 24.5%. Furthermore, it was found that the insufficiently active older adults with low SB (G3) (PR: 2.28; 95%CI: 1.09-4.76), and those insufficiently active with high SB (G4) (PR: 4, 14; 95%CI: 1.95-8.70), were more likely to experience the assessed outcome. Evidence showed that, among the older adults in Aiquara the prevalence of dynapenia was high in the presence of an insufficient level of PA, especially when combined with greater exposure to SB

RESUMO Esta pesquisa teve como objetivo analisar a associação do nível de atividade física (AF) combinado à exposição ao comportamento sedentário (CS) com a dinapenia em idosos. Estudo epidemiológico, transversal, conduzido com 208 idosos de Aiquara, Bahia, Brasil. A AF habitual e o CS foram quantificados pelo International Physical Activity Questionnaire. A partir destas informações, dividiu-se os participantes em grupos (G): G1) suficientemente ativos e baixo CS; G2) suficientemente ativos e elevado CS; G3) insuficientemente ativos e baixo CS; e G4) insuficientemente ativos e elevado CS. A avaliação da dinapenia foi realizada a partir dos valores, em quilograma-força (kgf), da força de preensão manual (mulheres: 18,37 kgf; homens: 26,75 kgf). A análise descritiva foi conduzida por meio de frequências absolutas e relativas, média e desvio padrão. Para a análise inferencial utilizou-se a regressão de Poisson, com estimador robusto, cálculo das Razões de Prevalência (RP) e de seus respectivos Intervalos de Confiança (IC) de 95,0%. Observou-se que as médias de idade das mulheres e dos homens, foram, respectivamente, 71,0 ± 6,7 e 72,3 ± 8,1 anos e a prevalência de dinapenia observada foi na ordem de 24,5%. Ademais, averiguou-se que os idosos insuficientemente ativos com baixo CS (G3) (RP: 2,28; IC95%: 1,09-4,76), e os insuficientemente ativos com elevado CS (G4) (RP: 4,14; IC95%: 1,95-8,70), apresentaram maior probabilidade ao desfecho analisado. As evidências verificadas mostraram que, entre os idosos de Aiquara, a prevalência de dinapenia foi elevada na presença do nível de AF insuficiente, especialmente quando combinado a uma maior exposição ao CS.

Anthropometric indicators of obesity for the prediction of metabolic syndrome in the older adults / Indicadores antropométricos de obesidade na predição de síndrome metabólica em idosos

INTRODUCTION: The anthropometric indicators of obesity may be important in predicting metabolic syndrome (MS). OBJECTIVE: To evaluate the anthropometric indicators as predictors of MS and verify the association of these indicators with MS in older adult individuals of both sexes. METHODS: Cross-sectional epidemiological study was carried out with 222 individuals aged 60 years or older residents in the urban area of Aiquara, Bahia state, Brazil. Older adults were measured for anthropometric indicators: body mass index (BMI), waist-to-height ratio (WHtR), waist circumference, conicity index, the sum of skinfolds; blood pressure; biochemical variables: fasting glucose, triglycerides, total cholesterol, and fractions. For the diagnosis of MS, the definition of the International Diabetes Federation was used. Descriptive and inferential data analysis was tested using correlation, the Poisson regression technique, and the Receiver Operating Characteristic (ROC) curve. RESULTS: The prevalence of MS was 62.3%. There was a correlation of all anthropometric indicators with MS in both sexes. The indicators of visceral fat had a strong association in that these indicators had an area under the ROC curve higher than 0.76 (CI95% 0.66­0.85). Thus, most results showed a weak correlation. CONCLUSION: All anthropometric indicators can be used to predict MS in older adults for both sexes, however, BMI and WHtR showed the best predictions.

INTRODUÇÃO: Os indicadores antropométricos de obesidade podem ser importantes na predição da síndrome metabólica (SM). OBJETIVO: Avaliar os indicadores antropométricos como preditores da SM, bem como verificar a associação desses indicadores com a SM em idosos de ambos os sexos. MÉTODOS: Estudo epidemiológico transversal realizado com 222 indivíduos com 60 anos ou mais residentes na zona urbana de Aiquara-BA, Brasil. Os idosos foram avaliados quanto aos indicadores antropométricos: índice de massa corporal (IMC), razão cintura-estatura (RCEst), circunferência da cintura, índice de conicidade, soma de dobras cutâneas; pressão sanguínea; bioquímicos: glicemia em jejum, triglicérides, colesterol total e frações. Foram classificados quanto à presença de SM de acordo com a Federação Internacional de Diabetes. A análise descritiva e inferencial dos dados foi testada utilizando correlação, a técnica de regressão de Poisson e a curva Receiver Operating Characteristic (ROC). RESULTADOS: A prevalência de SM foi de 62,3%. Houve correlação de todos os indicadores antropométricos com a SM em ambos os sexos. Os indicadores de gordura visceral apresentaram forte associação, pois possuem área abaixo da curva ROC superior a 0,76 (IC95% 0,66-0,85). Assim, a maioria dos resultados apresentou correlação fraca. CONCLUSÃO: Todos os indicadores antropométricos podem ser usados para rastrear a SM em idosos de ambos os sexos, no entanto, o IMC e a RCEst apresentaram as melhores previsões.

Factors associated with dynapenia in older adults in the northeast of Brazil / Fatores associados à dinapenia em idosos do nordeste brasileiro

ABSTRACT This study identified factors associated with dynapenia in older adults residing in a small town in northeastern Brazil. It is a population-based study conducted with 208 senior citizens (58.7% women) from Aiquara, BA. Sociodemographic, behavioral and health information were obtained from face-to-face interviews, and nutritional status was assessed by body mass index. To measure their level of physical activity and sedentary behavior, the International Physical Activity Questionnaire was used. Dynapenia was diagnosed by sex, from the 25th percentile of handgrip strength, by means of a hydraulic dynamometer. For inferential analyses, Poisson regression was used, with a robust estimator, calculation of Prevalence Ratios (PRs) and their respective 95% Confidence Intervals (CIs). The prevalence of dynapenia was higher in older adults aged 70-79 (PR: 3.21; 95%CI: 1.55-6.64) and ≥80 years (PR: 4.91; 95%CI: 2.32-10.39), in those with low weight (PR: 2.20; 95%CI: 1.26-3.82), in those who are insufficiently active (PR: 1.99; 95%CI: 1.12-3.54), and among those with high level of sedentary behavior (PR: 1.88; 95%CI: 1.19-2.98). The factors identified as being associated with dynapenia were: age between 70 and 79 and ≥80 years, insufficient level of physical activity; high level of sedentary behavior, and low weight.

RESUMO Este estudo identificou os fatores associados à dinapenia em idosos residentes em um município de pequeno porte do Nordeste brasileiro. Trata-se de um estudo populacional, conduzido com 208 idosos (58,7% mulheres) de Aiquara-BA. As informações sociodemográficas, comportamentais e de condições de saúde foram obtidas em entrevistas face a face, e o estado nutricional foi avaliado pelo índice de massa corporal. Para mensuração do nível de atividade física e do comportamento sedentário, utilizou-se o International Physical Activity Questionnaire. O diagnóstico da dinapenia foi realizado por sexo, a partir do percentil 25 da força de preensão manual, averiguada com um dinamômetro hidráulico. Para análises inferenciais foi utilizada a regressão de Poisson, com estimador robusto, cálculo das Razões de Prevalência (RP) e de seus respectivos intervalos de confiança de 95% (IC). A prevalência de dinapenia foi maior nos idosos com idade entre 70-79 (RP: 3,21; IC95%: 1,55-6,64) e ≥80 anos (RP: 4,91; IC95%: 2,32-10,39), nos com baixo peso (RP: 2,20; IC95%: 1,26-3,82), nos insuficientemente ativos (RP: 1,99; IC95%: 1,12-3,54) e entre os com elevado comportamento sedentário (RP: 1,88; IC95%: 1,19-2,98). Identificou-se que os fatores associados à dinapenia foram: idade entre 70-79 e ≥80 anos, nível de atividade física insuficiente; elevado comportamento sedentário e baixo peso.

The D allele of angiotensin-converting enzyme gene is associated with a worse autonomic heart control in community-based older adults.

The relationship between the Renin-Angiotensin-Aldosterone System (RAAS) and modulation of the Autonomic Nervous System (ANS) is reported as complex and bidirectional. Thus, the present study aimed to compare autonomous heart control, through symbolic analysis parameters, in the older adults carrying different ACE I/D gene polymorphisms (rs4646994). Two hundred four older adults comprised the study population and were grouped according to the ACE I/D gene polymorphism: II + ID genotype and DD genotype. Successive RR intervals were recorded along 5 min and analyzed with Symbolic Analysis (SA) method. 0 V%, 1 V% and 2 V% patterns were quantified and compared between groups. A linear mixed model analysis was used to determine between-group differences in symbolic analysis parameters (0 V%, 1 V% and 2 V%), taken groups as fixed factor and sex, use of ACE inhibitors and Angiotensin II receptor type I blockers as random factors. The Bayesian analysis was carried out to check the magnitude of the evidence. The results of this study indicate that older adults carrying the DD genotype have statistically greater sympathetic modulation (0 V%) and poor sympathovagal balance (1 V%), but the Bayesian analysis indicate only an anecdotal effect. Sympathetic predominance is recognized a worrying condition, since may predisposes to cardiovascular risk.

Differentiation of face and auricular shape resulting from diabetes and hypertension in the elderly

The prevalence global of noncommunicable chronic diseases as diabetes and hypertension worldwide has been disregarded until recently by policy makers. In addition, these diseases have growing with the aging of the population. This study sought to identify changes in face shape from the frontal and side views in elderly people diagnosed with diabetes and hypertension. 205 individuals were studied, with 60 years or more, from both sexes, with different ethnicities, and cognition intact. With a digital camera, photos were taken of the front and side and based on these images landmarks for measurement were determined. For statistical analysis, ANOVA, Canonical Variates Analysis, Mahalanobis distance and Thin-Plate Spline were realized. Given sexual dimorphism, the sexes were analyzed separately. From the ANOVA, significant differences (p<0.01) for individuals with diabetes, hypertension, and patients with both or neither of the diseases were observed. The groups were separated by the Canonical Variates and Mahalanobis distance and independent of edentulism, sex or ethnicity. A morphofacial characteristics for the front and side views (especially in the ear region) that identified individuals with these chronic diseases was observed. This methodology can contribute in a specific manner to the identification of at risk populations and help to promote preventative measures for these conditions.

Abstract: This study aimed to outline the profile of emergency-medical care performed to the elderly population through the prehospital regional medical-emergency regulation center and the mobile emergency-care system. The data analyzed here was extracted from a database of the emergency-calls made to reach out the of the regional medical-emergency regulation center and the mobile emergency-care system over the year of 2013 at the city of Jequié, Brazil. The absolute and relative frequencies were calculated for the variables evaluated. the regional medical-emergency regulation center received 3,505 calls and 2,066 ambulance units were sent out. Both at the regional medical-emergency regulation center and the ambulance crew the age of the patients assisted ranged from 60 to 79 years old, and most of the emergency-calls were attended during weekdays and during the morning shifts. Most of the elderly assistment were at their households, having clinical assistance, and afterwards they were conducted to a public hospital network. Hypertensive crisis, chronic pain, neurological and dyspnoea issues have prevailed among other diagnosis. Thus, we conclude here that the emergency- prehospital care is essential to meet the urgent demands of the elderly population.

Craniofacial geometric morphometrics in the identification of patients with sickle cell anemia and sickle cell trait

ABSTRACT Objective: The aims of this study were to identify the main characteristics regarding the shape and size of the craniofacial region in patients with sickle cell anemia (SCA) and sickle cell trait (SCT) and in unaffected patients using geometric morphometrics and to check the efficiency of this method. Material and Methods: A cross-sectional analytical study of 45 patients (15 in each group) was performed. Lateral radiographs of the skull were used for the analysis. Seventeen landmarks and semilandmarks were placed for the measurements. The Pocrustes analysis of variance (ANOVA), regression analysis, multivariate analysis of variance, canonical variate analysis, Mahalanobis and Procrustes distances and unweighted pair group method with arithmetic mean (UPGMA) clustering were performed. Allometric effects and sex characteristics were not statistically significant (p> 0.05). Results: There were, however, significant differences (p< 0.05) in craniofacial shape among SCA, SCT and unaffected individuals. Those with SCA showed variations in the shape of the external auditory meatus and at the base of the occipital bone, in addition to the mandibular setback and upper incisor inclination, with a tendency towards prognathism. The individuals with SCT exhibited a similar craniofacial shape to those with SCA, but with slighter variations. Moreover, those with SCT were statistically closer in resemblance to unaffected individuals, given that SCT is not regarded as a disease. Conclusion: This demonstrates the efficiency of geometric morphometrics in the categorization of the assessed groups.

Hyperuricemia is associated with sympathovagal imbalance in older adults.

PURPOSE: This study aimed to compare heart rate variability (HRV) parameters obtained through symbolic analysis (SA), between older adults with and without hyperuricemia. METHODS: This is a cross-sectional study including 202 community-dwelling old adults, which was clinically stratified as with or without hyperuricemia, according to the cutoff point of serum uric acid ≥ 6 mg/dL for women and ≥ 7 mg/dL for men. Successive RR intervals were recorded along 5 min and analyzed with SA method. 0 V%, 1 V% and 2 V% patterns were quantified and compared between groups. Comparisons were carried out through parametric or nonparametric tests, according to the data distribution characteristics, evaluated by Kolmogorov-Smirnov test. The significance level was set as p ≤ 0.05 for all statistical procedures. RESULTS: The prevalence of hyperuricemia was 67.8 %, and the hyperuricemic older adults exhibited significant higher values for V0% and lower values for V2% parameters when compared to normouricemic older adults. CONCLUSION: These results suggesting a sympathovagal imbalance in hyperuricemic older adults, characterized by greater sympathetic predominance (0 V%) and lower vagal modulation (2 V%) at rest conditions.

Estudo comparativo sobre as condições de anemia em idosos / Comparative study on the conditions of anemia in elderly / Estudio comparativo sobre las condiciones de anemia en idosos

Objetivo: Comparar características sociodemográficas, comportamentais, condições de saúde e parâmetros laboratoriais entre idosos anêmicos e não anêmicos. Métodos: Estudo epidemiológico transversal realizado com 257 idosos. Para realizar as comparações utilizou-se o teste t para amostras independentes e o teste não paramétrico U de Mann-Whitney. Resultados: Encontrou-se maior proporção de anemia em idosos com idade acima de 80 anos (p=0,026), e maior proporção de dependência para atividades básicas (p=0,018) e instrumentais (p=0,010) da vida diária em idosos com anemia. Identificou-se diferença na distribuição da dosagem dos parâmetros laboratoriais, sendo as concentrações médias de ureia e creatinina maiores nos idosos anêmicos, e esses tiveram menores concentrações de glicemia, albumina, ALT/TGP, cálcio sérico e T3 total. Conclusão: A anemia não está relacionada exclusivamente ao processo de envelhecimento, mas sim resultado de múltiplos fatores como as condições sociodemográficas, de saúde, alimentares e de vida dos idosos

Objective: To compare sociodemographic, behavioral characteristics, health conditions and laboratory parameters among anemic and non - anemic elderly. Methods: Cross-sectional epidemiological study with 257 elderly subjects. To perform comparisons, the t-test for independent samples and the non-parametric Mann-Whitney U test were used. Results: There was a higher proportion of anemia in the elderly over 80 years (p = 0.026), and a higher proportion of dependence on basic activities (p = 0.018) and instrumental (p = 0.010) daily activities in elderly patients with anemia. Differences were observed in the distribution of laboratory parameters, with mean values of urea and creatinine being higher in anemic elderly, with lower concentrations of glycemia, albumin, ALT / TGP, serum calcium and total T3. Conclusion: Anemia is not exclusively related to the aging process, but is a result of multiple factors such as sociodemographic, health, food and life conditions of the elderly

Metabolic syndrome components and face shape variation in elderly / Componentes da síndrome metabólica e variação na forma da face em idosos

Abstract The aim of this study was to identify the metabolic syndrome (MS) components mostly influencing face shape in elderly individuals. This is a cross-sectional epidemiological study carried out with elderly individuals living in Aiquara County, Bahia State. Facial images at frontal view and MS were classified according to the National Cholesterol Education Program's Adult Treatment Panel III (revised version). Discriminant function, cross validation and distance Mahalanobis D2 were used to extract face shape variations due to MS. Principal Component Analysis (PCA) was used to evaluate MS components' influence on face shape. The total of 193 elderly individuals were selected; there were significant differences in face shape due to MS (p <0.01) in both sexes. PCA 1 showed HDL-C in men, which accounted for 37% of the total variation. HDL-C in biplot is associated with individuals who do not have MS and with elderly individuals with MS - there was correlation between waist circumference and triglycerides. PCA 1 represented 33.2% of the total variation in women; this outcome is explained by triglycerides. There was association between blood glucose and waist circumference in biplot. HDL-C is related to women who do not have MS. Facial variations affected by MS did not derive from the action of any of the MS components, but from the association between them. Thus, geometric morphometrics emerges as a promising method that makes it possible identifying heart disease and metabolic risk factors according to face shape features.

Resumo Objetivou-se identificar dentre os componentes da síndrome metabólica (SM) o que mais interfere na forma da face em idosos. Trata-se de um estudo epidemiológico, transversal, realizado com idosos residentes de Aiquara-BA. Foram obtidas imagens faciais da vista frontal e a SM foi classificada segundo o National Cholesterol Education Program's Adult Treatment PanelIII, revisado. A partir da função discriminante, validação cruzada e a distância D2 Mahalanobis, foram extraídas as variações da forma em função da SM. Para avaliar a influência dos componentes da SM na forma da face, utilizou-se a Análise de Componentes Principais (ACP). Participaram 193 idosos e foram identificadas diferenças significativas na forma da face em relação a SM (p<0,01) em ambos os sexos. Para os homens, o ACP 1 foi o HDL-C, este explicou 37% da variação total. Pelo biplot, o HDL-C está associado aos indivíduos que não possuem SM e em idosos com SM, houve uma correlação entre a circunferência da cintura e os triglicerídeos. Para as mulheres, o ACP 1 representou 33,2% da variação total, explicado pelos triglicerídeos. Pelobiplot, houve uma relação entre glicose e circunferência da cintura. Nas mulheres, o HDL-C está relacionado com quem não tem SM. As variações faciais acometidas pela SM, não foram decorrentes da ação de um dos componentes da mesma, mas das relações entre eles. Assim, a morfometria geométrica se mostra como método promissor e possibilita identificar a partir da forma da face fatores de risco cardiovascular e metabólico.
