RESUMO

BACKGROUND: Sedentary behavior is linked to excess fat mass; however, this association may be inconclusive due to potential measurement errors in self-reported sedentary behavior. OBJECTIVE: To assess the association between changes in sedentary behavior and fat mass in a Cohort of Health Workers (HWCS) from 2004 to 2010. METHODS: A total of 1,285 adults participating in the Cohort of Health Workers were evaluated in 2004 and 2010. Fat mass (kg) was measured by dual X-ray absorptiometry. A self-administered questionnaire was used to estimate the sedentary behavior. Sedentary behavior was also estimated using accelerometry in a sample of 142 health workers. Accelerometry data were used to correct self-reported sedentary behavior using a generalized linear model, which included values for sleeping time, age, sex, sedentary behavior, glucose, and triglycerides. Concordance between both methods was assessed using a kappa and Bland-Altman analysis. Once sedentary behavior was corrected, the values were used to evaluate the association between changes in sedentary behavior and body fat mass using a fixed effect model in the cohort, adjusting for confounders. RESULTS: Self-reported sedentary behavior was 2.8 ± 1.8 and 2.3 ± 1.6 h/day, and body fat mass was 24.9 ± 8.1 and 26.8 ± 8.5 kg in 2004 and 2010, respectively. After applying the correction model, the self-reported sedentary behavior was 7.6 ± 1.2 and 7.5 ± 1.2 h/day in 2004 and 2010, respectively. For every hour increase in corrected sedentary behavior, there was an observed increase of 0.847 (p > 0.001) kg in body fat mass during the 6.8 years in the Cohort of Health Workers from 2004 to 2010. Conversely, non-corrected self-reported sedentary behavior was associated with a non-significant reduction of 0.097 kg (p = 0.228) for every hour of sedentary behavior. CONCLUSIONS: Increased sedentary behavior was associated with increased body fat mass when corrected self-reported sedentary behavior was used. Implementing public health strategies to reduce sedentary behavior is imperative.

RESUMO

O Brasil vive uma transição demográfica que favorece o aparecimento e desenvolvimento de doenças crônicas não transmissíveis (DCNT). Em um cenário em que as DCNT estão entre as principais causas de mortes, reforçar a importância de uma alimentação saudável é imprescindível, e medidas preventivas tomam lugar de destaque. Pensando nisso, foram realizadas 11 intervenções de educação alimentar e nutricional em um grupo de atividade física intergeracional, com o objetivo de promover autonomia alimentar. O estudo contou com 25 participantes, na faixa etária de 37 a 83 anos, sendo a maior incidência de 61 a 69 anos (n=12) e predominância de pessoas do gênero feminino (92%). Os parâmetros para avaliar o grupo foram os feedbacks das(os) participantes e o grau de adesão, no qual houve aumento significativo ao longo do período interventivo. Destaca-se a importância de ampliar a abordagem dos hábitos alimentares saudáveis em diversos ambientes, sendo os grupos de atividades físicas um campo fértil, que requer a adaptação da linguagem e formato das atividades, considerando o nível de escolaridade das(os) participantes. Assim, a educação alimentar e nutricional pode ser usada como ferramenta efetiva para a promoção da saúde, a prevenção e o tratamento de DCNT.


Brazil is undergoing a demographic transition that favors the onset and development of chronic non-communicable diseases (NCDs). In a scenario where NCDs feature among the main causes of death, reinforcing the importance of healthy eating is essential and preventive measures should take place. Consequently, eleven Food and Nutritional Education interventions were conducted with an intergenerational physical activity group to promote food autonomy. A total of 25 individuals aged 37 to 83 years participated in the study, with the highest prevalence of 61 to 69 years (n=12) and women (92%). Evaluation parameters were participant feedback and the degree of adherence, which increased significantly over the interventional period. Results highlight the importance of broadening the approach to healthy eating habits in various environments, with physical activity groups being a fertile setting which requires adapting language and the format of activities according to participants' schooling level. Nutritional Food Education can be used as an effective tool for health promotion, prevention and treatment of NCDs.

RESUMO

Resumo Fundamento A doença cardiovascular (DCV) é uma série de doenças que afetam o coração ou os vasos sanguíneos. Objetivos Avaliar a relação entre os níveis de pressão arterial (PA) definidos pelo American College of Cardiology/American Heart Association (ACC/AHA) de 2017 diretriz e risco de DCV/doença cardiovascular aterosclerótica (DCVA) para pessoas de meia-idade e idosos na China. Métodos Um total de 6.644 pessoas de meia-idade e idosas do Estudo Longitudinal de Saúde e Aposentadoria da China CHARLS (China Health and Retirement Longitudinal Study) foram finalmente incluídas. De acordo com a diretriz ACC/AHA de 2017, todos os indivíduos foram divididos em quatro grupos: PA normal, PA elevada, hipertensão estágio 1 e hipertensão estágio 2. O desfecho deste estudo foi considerado o risco de DCV e DCVA. Modelos de regressão COX univariados e multivariados foram adotados para examinar a relação da classificação de PA ACC/AHA de 2017 com o risco de DCV. Modelos de regressão logística univariada e multivariada foram utilizados para investigar a associação entre os níveis de PA e o risco de DCVA. Foram realizadas análises de subgrupos baseadas em idade, sexo e uso de medicamentos anti-hipertensivos. P<0,05 foi aceito como estatisticamente significativo. Resultados Após ajustar todas as covariáveis, em comparação com pacientes de meia-idade e idosos com PA normal, descobrimos que pacientes com hipertensão estágio 1/2 estavam associados a um maior risco de DCV, separadamente. Simultaneamente, também observamos uma associação positiva entre indivíduos com PA elevada, hipertensão estágio 1, hipertensão estágio 2 e maior risco de DCVA no modelo totalmente ajustado. O resultado das análises de subgrupos indicou que a relação entre hipertensão estágio 1/2 e DCV/DCVA alta foi robusta em diferentes idades e sexos, e participantes sem uso de medicamentos anti-hipertensivos. Conclusão A classificação da PA de acordo com as diretrizes de PA da ACC/AHA de 2017 pode ser aplicada à população chinesa.


Abstract Background Cardiovascular disease (CVD) is a series of diseases affecting the heart or blood vessels. Objectives To assess the relationship between blood pressure (BP) levels defined by the 2017 American College of Cardiology/American Heart Association (ACC/AHA) guideline and CVD/atherosclerotic cardiovascular disease (ASCVD) risk for middle-aged and elderly people in China. Methods A total of 6,644 middle-aged and elderly people from the China Health and Retirement Longitudinal Study (CHARLS) were finally included. According to the 2017 ACC/AHA guideline, all subjects were divided into four groups: normal BP, elevated BP, stage 1 hypertension, and stage 2 hypertension. The outcome of this study was considered as the risk of CVD and ASCVD. Univariate and multivariate COX regression models were adopted to examine the relationship of the 2017 ACC/AHA BP classification with the risk of CVD. Univariate and multivariate logistic regression models were used to investigate the association between BP levels and ASCVD risk. Subgroup analyses based on age, gender, and use of antihypertensive drugs were performed. P<0.05 was accepted as statistically significant. Results After adjusting all covariates, compared to middle-aged and elderly patients with normal BP, we found that patients with stage 1/2 hypertension were associated with a higher risk of CVD, separately. Simultaneously, we also observed a positive association between individuals with elevated BP, stage 1 hypertension, stage 2 hypertension, and higher ASCVD risk in the fully adjusted model. The result of subgroup analyses implied that the relationship between stage 1/2 hypertension and CVD/ high ASCVD was robust in different ages and genders, and participants without using antihypertensive drugs. Conclusion BP classification under the 2017 ACC/AHA BP guidelines may apply to the Chinese population.

RESUMO

INTRODUCTION: A lower ability to buffer pulse pressure (PP) in the face of increasing mean arterial pressure (MAP) may underlie the disproportionate increase in systolic blood pressure (SBP) in women from young adulthood through middle-aged relative to men. AIM: To evaluate the contribution of MAP to the change in PP and pressure wave contour in men and women from young adulthood to middle age. METHODS: Central pressure waveform was obtained from radial artery applanation tonometry in 312 hypertensive patients between 16 to 49 years (134 women, mean age 35 ± 9 years), 185 of whom were on antihypertensive treatment. RESULTS: Higher MAP levels (≥ 100 mmHg) were significantly associated with higher brachial and central SBP (P < 0.001), PP (P < 0.001), incident wave (P = 0.005), AP (P < 0.001), and PWV (P < 0.001) compared to lower MAP levels. The relationship between MAP and brachial PP (P < 0.001), central PP (P < 0.001), incident wave (P < 0.001), and AP (P < 0.01), but not PWV, strengthens with age. The age-related increase in the contribution of MAP to brachial PP (P < 0.001), central PP (P < 0.001), and incident wave (P < 0.001) was more prominent in women than in men beginning in the fourth decade. In multiple regression analyses, MAP remained a significantly stronger predictor of central PP and incident wave in women than in men, independent of age, heart rate, and antihypertensive treatment. In turn, age remained a significantly stronger predictor of central PP and incident wave in women than in men, independent of MAP, heart rate, and antihypertensive treatment. CONCLUSIONS: Women of reproductive age showed a steeper increase in PP with increasing MAP, despite comparable increases in arterial stiffness in both sexes. The difference was driven by a greater contribution of MAP to the forward component of the pressure wave in women.

RESUMO

Given the importance of dementia syndrome and its impacts on the population, interest in studying modifiable risk factors for dementia is growing. Objective: To compare the prevalence of risk factors for dementia in middle-aged and older adults over a two-year period and to identify what variables in baseline were predictive of cognitive decline in the follow-up. Methods: Longitudinal and quantitative study, with follow-up evaluation after two years, conducted with 200 participants aged 45 years or more, registered in Primary Care Units. In the baseline (2018/2019) and follow-up (2021) assessments, sociodemographic data were collected, and cognitive performance and risk factors for dementia were evaluated (education, hearing loss, head trauma, high blood pressure, alcohol use, obesity, smoking, depressive symptoms, social isolation, physical inactivity, and diabetes mellitus). Data were compared using the McNemar's test. Individual multinomial logistic regression models were performed to identify the factors associated with cognitive decline after two years. Results: The percentages of low education, traumatic brain injury, and smoking remained the same in both assessments. There was a significant increase in the prevalence of high blood pressure (from 55.0 to 62.0%) and physical inactivity (from 58.5 to 74.5%) and a significant reduction in social isolation (from 25.0 to 18.0%). Participants with depressive symptoms in baseline had a higher risk of cognitive decline in follow-up. Conclusion: There was an increase in the prevalence of high blood pressure and physical inactivity and a reduction in social isolation after two years. Depressive symptoms predict cognitive decline.

RESUMO

INTRODUCTION: This study aimed to investigate the association between handgrip strength and suicidal ideation in representative samples of adults aged ≥50 years from six LMICs (China, Ghana, India, Mexico, Russia, and South Africa). METHODS: Cross-sectional, community-based data from the World Health Organization's Study on Global Aging and Adult Health were analyzed. Handgrip strength quintiles by sex were created based on the average value of two handgrip measurements of the dominant hand. Self-reported information on past 12-month suicidal ideation was collected. Multivariable logistic regression analysis was conducted to assess associations. RESULTS: Data on 34,129 individuals were analyzed [mean (SD) age 62.4 (16.0) years; age range 50-114 years; 52.1% females]. After adjustment for potential confounders, in the overall sample, compared to the handgrip strength quintile with the highest values [Quintile 1 (Q1)], Q2, Q3, Q4, and Q5 were associated with significant 2.15 (95% CI = 1.05-4.39), 2.78 (95% CI = 1.06-7.32), 3.53 (95% CI = 1.68-7.42), and 6.79 (95% CI = 2.80-16.48) times higher odds for suicidal ideation. CONCLUSIONS: Lower handgrip strength was significantly and dose-dependently associated with higher odds for suicidal ideation in adults aged ≥50 years from LMICs. Future longitudinal studies are needed to understand the underlying mechanisms, and whether increasing general muscular strength and physical function may lead to reduction in suicidal ideation.

RESUMO

Resistance training (RT) can increase the heat shock response (HSR) in the elderly. As middle-aged subjects already suffer physiological declines related to aging, it is hypothesized that RT may increase the HSR in these people. To assess the effects of resistance training on heat shock response, intra and extracellular HSP70, oxidative stress, inflammation, body composition, and metabolism in middle-aged subjects. Sixteen volunteers (40 - 59 years) were allocated to two groups: the trained group (n = 7), which performed 12 weeks of RT; and the physically inactive-control group (n = 9), which did not perform any type of exercise. The RT program consisted of 9 whole-body exercises (using standard gym equipment) and functional exercises, carried out 3 times/week. Before and after the intervention, body composition, muscle mass, strength, functional capacity, and blood sample measurements (lipid profile, glucose, insulin, oxidative damage, TNF-α, the HSR, HSP70 expression in leukocytes, and HSP72 in plasma) were performed. The HSR analysis demonstrated that this response is maintained at normal levels in middle-aged people and that RT did not cause any improvement. Also, RT increases muscle mass, strength, and functional capacity. Despite no additional changes of RT on the antioxidant defenses (catalase, glutathione peroxidase, and reductase) or inflammation, lipid peroxidation was diminished by RT (group x time interaction, p = 0.009), indicating that other antioxidant defenses may be improved after RT. HSR is preserved in middle-aged subjects without metabolic complications. In addition, RT reduces lipid peroxidation and can retard muscle mass and strength loss related to the aging process.

RESUMO

Executive functions have been widely studied in the extreme of ages, but studies in middle-aged adults remain largely neglected. Education and gender are known to influence cognitive performance; however, their effect on executive function in middle-aged adults remains unclear. Objective: The study aimed to observe the effect of hierarchy of educational qualifications (graduate, postgraduate, and PhD) and gender on various executive function tests across middle-aged adults with or without comorbidity. Methods: A total of 66 middle-aged individuals volunteered for the study (mean age=48.45±5.45 years; 20 graduates, 28 postgraduates, and 18 PhD; 36 males and 30 females; 38 healthy adults and 28 adults with comorbidities). Each subject performed a test assessing short-term memory, spatial working memory, and multitasking abilities on the Cambridge Neuropsychological Test Automated Battery with rest periods in no specific order of tests. Key parameters of cognitive tests were analyzed for differences in educational qualifications (ANOVA), gender (t-test), and the effect of comorbidity as a covariate (ANCOVA). Results: PhDs performed significantly better (p<0.05) in multitasking than graduates and had superior visuospatial working memory (fewer errors). Differences in simultaneous matching abilities, lower incongruence cost and multitasking cost were statistically significant in healthy females than in males. Conclusion: On considering adults with comorbidity, those with higher educational attainment retained the ability to multitask compared to their healthy counterparts, which was not seen in the group with lower educational attainment. Thus, higher educational attainment attenuated the influence of comorbidities and deterioration of executive functions in general in middle-aged adults.


As funções executivas têm sido amplamente estudadas no extremo das idades, mas os estudos na meia-idade permanecem amplamente negligenciados. Educação e gênero são conhecidos por influenciar o desempenho cognitivo, no entanto, seu efeito na função executiva em adultos de meia-idade ainda não está claro. Objetivo: O estudo teve como objetivo observar o efeito da hierarquia de qualificações educacionais (graduação, pós-graduação e doutorado) e gênero em vários testes de função executiva em adultos de meia-idade com ou sem comorbidade. Métodos: Sessenta e seis indivíduos de meia idade se voluntariaram para participar do estudo (idade média=48,45±5,45 anos, 20 graduados, 28 pós-graduados e 18 doutores; 36 homens e 30 mulheres; 38 saudáveis e 28 adultos com comorbidades). Cada sujeito realizou um teste avaliando memória de curto prazo, memória de trabalho espacial e habilidades multitarefa na Bateria Automatizada de Testes Neuropsicológicos de Cambridge (Cambridge Neuropsychological Test Automated Battery ­ CANTAB) com períodos de descanso em nenhuma ordem específica de testes. Os principais parâmetros dos testes cognitivos foram analisados quanto às diferenças nas qualificações educacionais (ANOVA), sexo (teste t) e efeito da comorbidade como uma covariável (ANCOVA). Resultados: Os doutores tiveram desempenho significativamente melhor (p<0,05) em multitarefa do que os graduados e tiveram memória de trabalho visual-espacial superior (menos erros). As diferenças nas habilidades de correspondência simultânea, menor custo de incongruência e custo de multitarefa foram estatisticamente significativas em mulheres saudáveis do que em homens. Conclusão: Ao considerar os adultos com comorbidade, aqueles com maior escolaridade mantiveram a capacidade de multitarefa como seus pares saudáveis, o que não foi observado no grupo com menor escolaridade. Assim, maior escolaridade atenuou a influência de comorbidades e deterioração das funções executivas em geral, em adultos de meia-idade.

RESUMO

Background: Middle-aged and older adults often mistakenly underestimate the risk to which they are exposed when they engage in risky sexual behaviors. Furthermore, a reliable and valid measurement of the construct is necessary to capture its scope and meaning. Objective: To validate the structure of the Perceived Risk Scale for STIs in middle-aged and older adults, identify their perceived risk of STIs, and identify their relationship with some sociodemographic characteristics. Methods: The sample was composed of 295 middle-aged and older adults. A virtual online sampling was used. Males and females aged 50 years and older, sexually active in the last 12 months, were included. To measure the perceived risk of STIs, the scale of perceived risk for human immunodeficiency virus (HIV) was adapted, and a confirmatory factor analysis of the proposed three-factor structure was carried out. Results: The proposed structure of the scale was found to present acceptable adjustment rates (X 2= 48.283, p <.001; CFI = .962, RMSEA = .079, GFI = .963, TLI = .938). 28.1% of the participants presented low perceived risk; 46.8%, medium perceived risk; and 25.1%, high perceived risk. Association between marital status and perceived risk of STIs was identified. Conclusion: The Perceived Risk Scale for STIs is a reliable and valid instrument for capturing perceived risk of STIs in middle-aged and older adults. An appropriate measurement is considered important to accurately examine the relationship between perceived risk and behavior.


Antecedentes: Los adultos de mediana y tercera edad suelen subestimar erróneamente el riesgo al que se exponen cuando realizan conductas sexuales de riesgo, además, es necesaria una medición fiable y válida del constructo para captar su alcance y significado. Objetivo: Validar la estructura de la Escala de Riesgo Percibido a las ITS en adultos de mediana y tercera, identificar su riesgo percibido a las ITS e identificar su relación con algunas características sociodemográficas. Métodos: La muestra estuvo compuesta por 295 adultos de mediana y tercera edad. Se utilizó un muestreo virtual en línea. Se incluyeron hombres y mujeres de 50 años o más, se-xualmente activos en los últimos 12 meses. Para medir el riesgo percibido a las ITS se adaptó la escala de riesgo percibido al Virus de Inmunodeficiencia Humana (VIH) y se realizó un análisis factorial confirmatorio de la estructura propuesta conformada por tres factores. Resultados: Se comprobó que la estructura propuesta de la escala presentaba mostró índices de ajuste aceptables (X2 = 48.283, p <.001; CFI = .962, RMSEA = .079, GFI = .963, TLI = .938). El 28.1% de los participantes presentó un riesgo percibido bajo, el 46.8% un riesgo percibido medio y el 25.1% un riesgo percibido alto. Se identificó la asociación entre el estado civil y el riesgo percibido de ITS. Conclusiones: La Escala de Riesgo Percibido de ITS es un instrumento fiable y válido para captar el riesgo percibido a las ITS en adultos de mediana y tercera edad. Se considera importante una medición adecuada para examinar con precisión la relación entre el riesgo percibido y la conducta.
