“…Períodos prolongados na posição sentada durante um dia também podem influenciar na massa muscular reduzida em idosos. Como verificado no estudo de Gianoudis et al 32 o tempo de visualização prolongado está associado com menor massa magra na perna em idosos, ajustado pela massa de gordura. Reduzir o comportamento sedentário e aumentar a prática de atividades físicas de intensidade leve à moderada pode ser estratégias efetivas para alcançar benefícios para a saúde 33 .…”

ResumoThe loss of muscle mass in older adults is negatively associated with health, which makes it necessary to identify modifiable behavioral habits that may aggravate this condition in this population. In this context, the objectives of the present study were to describe the characteristics of older adults according to reduced muscle mass status and verify its association with sedentary behavior. This was a cross-sectional population-based study, conducted in 24 cities in the Regional Healthcare Administration of Uberaba/Minas Gerais. Older adults (≥ 60 years) from both sexes meeting the inclusion criteria answered a structured questionnaire on sociodemographic, health, and habits information. Participants also underwent measurement of anthropometric variables. Sitting time was measured using the validated questions from the IPAQ. The chi-square statistic was used to examine differences between the prevalence of reduced muscle mass and sociodemographic variables, health and habits. Poisson regression was used to analyze the association between reduced muscle mass and exposure to sedentary behavior. Results: 3.223 older adults with mean age of 70 years (SD = 7.26) took part in the study. Of these total, 20.9% (n = 674) presented reduced muscle mass, being statistically different according to age, schooling, marital status, monthly family income, waist circumference, body mass index, smoking and sedentary behavior. According to the adjusted analysis, older adults who spent ≥ 330 minutes/day sitting demonstrated higher likelihood for reduced muscle mass (PR = 1.18; CI95%: 1.04-1.34). Prolonged sitting time is associated with reduced muscle mass in older adults. Keywords:Aged. Nutritional Status.

Estudo transversal, realizado em 24 municípios da Superintendência Regional de Saúde de Uberaba/Minas Gerais. Seguindo os critérios de inclusão, os idosos (≥ 60 anos), de ambos os sexos, responderam um questionário estruturado em forma de entrevista com informações sociodemográficas, saúde, hábitos e mensuração de variáveis antropométricas. O tempo sentado foi avaliado conforme as perguntas do IPAQ. Utilizou-se a estatística qui-quadrado para verificar as diferenças encontradas entre as prevalências da massa muscular reduzida e as variáveis sociodemográficas, saúde e hábitos. A regressão de Poisson foi utilizada para analisar a associação entre a massa muscular reduzida e a exposição ao comportamento sedentário. Foram analisados 3.223 idosos, com média de idade de 70 anos (DP=7,26). Do total de idosos, 20,9% (n=674) apresentaram massa muscular reduzida, sendo estatisticamente diferente de acordo com faixa etária, ...

“…In the present study, logistic models were used and such association was observed in both models investigated (univariate and multiple). Other studies have also found an association between high leisure-time sedentary behavior and low functionality with the use of different tests and physical capacities 17,19,20,21 . One of the factors that may explain the fact of an individual to remain for long periods in sedentary behavior and affect functionality refers to the multifactorial origin of reduced musculoskeletal function and sedentary lifestyle can be considered an important factor for this problem 22 .…”

-Sedentary behavior refers to activities with low energy expenditure, usually performed in sitting or lying positions, and includes behavior belonging to the current lifestyle, such as watching television. In the course of aging, this activity is performed for longer periods by individuals on a daily basis. This is worrying, since aging associated with sedentary behavior accentuates functionality decline. The aim of this study was to analyze the relationship between high leisure-time sedentary behavior and low functionality in older adults. The sample consisted of 375 older adults aged 60-97 years (70 ± 7 years), and of these, 114 (30%) were men and 261 (70%) women. Functionality was assessed by two functional tests and information related to sedentary behavior was obtained using the self-reported physical activity questionnaire proposed by Baecke et al. The chi-square test was used to verify the association between sedentary behavior and functionality, and binary logistic regression analysis was used to build the multiple model. Older individuals with high leisure-time sedentary behavior were more likely to have low functionality [OR 2.57; 95% CI 1.40 to 4.71] and [OR 2.35; 95% CI 1.29 to 4.29] regardless of gender, age, smoking, osteoporosis, arthritis / osteoarthritis, low back pain and physical activity. Extended permanence in sedentary behavior was associated with low functionality in older subjects. Preventive measures to stimulate the practice of physical activities and encourage the reduction of time spent in sedentary activities such as watching television should be adopted by health professionals in an attempt to maintain functionality among older adults.

“…Too much sitting time could be related to increased cardiovascular, metabolic, bone, muscle, cognitive, and even ophthalmologic risk (9)(10)(11)(12)(13)(14), which are, in turn, associated with disability. For example, a recent systematic review and meta-analysis with 800,000 participants found that sedentary time was positively associated with incidence of diabetes, cardiovascular events, and cardiovascular mortality (9).…”

Although the health effects of sedentary behavior are not well known, too much time spent seated has been associated with several disability-related indicators, such as sarcopenia, osteoporosis, cardiovascular diseases, cognitive impairment and alterations in vision (9)(10)(11)(12)(13)(14).…”

Associations between sedentary behaviour and body composition, muscle function and sarcopenia in community-dwelling older adults

Abstract: Higher levels of sedentary behaviour in older adults were associated with reduced muscle mass and an increased risk of sarcopenia in community-dwelling older adults, independent of physical activity.
