          Abstract

          ABSTRACT Introduction: Diabesity is characterized as a simultaneous condition of type 02 diabetes and obesity. Among the aspects that influence the development of diabetes, the time in sedentary behavior and the time of physical activity are important risk factors. Objectives: To estimate cut-off points for time spent in sedentary behavior and physical activity as a discriminator of the presence of diabesity and to evaluate the predictive ability of WC and PA to identify this condition in quilombola adults. Methodology: this is a cross-sectional study with a sample composed of 332 adults (age ≥ 50 years), participants in the study of the Epidemiological Profile of Quilombolas from Bahia living in the micro-region of Guanambi, Brazil. The data were obtained by means of interviews and anthropometric evaluation. Sociodemographic and lifestyle information (physical activity and sedentary behavior) were included. To analyze the cut-off point of Sedentary Behavior as a predictor of diabesity, the Receiver Operating Characteristic (ROC) curve was used. Results: Time in sedentary behavior >120 min/day and time in physical activity <240 min/week were the best cut-off points for discriminating diabesity in quilombola, with area under the ROC curve of 0.62, 95% CI (0.56-0.67) and 0.62 (95% CI: 0.55-0.67), respectively. Conclusions: The results showed that time in sedentary behavior and time in physical activity showed a good ability to discriminate the presence of diabesity among quilombola adults.

          RESUMO Introdução: A Diabesidade caracteriza-se como uma condição simultânea de diabetes tipo 02 e obesidade. Dentre os aspectos que influenciam o desenvolvimento da diabesidade, o tempo em comportamento sedentário e o tempo de atividade física apresentam-se como importantes fatores de risco. Objetivos: estimar pontos de corte para o tempo em comportamento sedentário e atividade física como discriminador de presença de diabesidade e avaliar a capacidade preditiva do CS e AF para identificar essa condição em adultos quilombolas. Metodologia: trata-se de estudo transversal com amostra composta por 332 adultos (idade ≥ 50 anos), participantes do estudo de Perfil Epidemiológico dos Quilombolas baianos residentes na microrregião de Guanambi, Brasil. Os dados foram obtidos por meio de entrevistas e avaliação antropométrica. Foram incluídas informações sociodemográficas e estilo de vida (atividade física e comportamento sedentário). Para a análise do ponto de corte do Comportamento Sedentário e o tempo de atividade física como preditores de diabesidade, foi utilizada a curva Receiver Opereting Characteristic (ROC). Resultados: Tempo em comportamento sedentário >120 min/dia e tempo de atividade física >240 min/semana foram os melhores pontos de corte para discriminar a diabesidade em quilombola, com área sob a curva ROC de 0,62, IC 95% (0,56-0,67) e 0,62 (IC 95%: 0,55-0,67), respectivamente. Conclusões: Os resultados mostraram que o tempo em comportamento sedentário e atividade física apresentaram uma boa capacidade para discriminar a presença de diabesidade entre adultos quilombolas.

          World Health Organization 2020 guidelines on physical activity and sedentary behaviour

          Objectives To describe new WHO 2020 guidelines on physical activity and sedentary behaviour. Methods The guidelines were developed in accordance with WHO protocols. An expert Guideline Development Group reviewed evidence to assess associations between physical activity and sedentary behaviour for an agreed set of health outcomes and population groups. The assessment used and systematically updated recent relevant systematic reviews; new primary reviews addressed additional health outcomes or subpopulations. Results The new guidelines address children, adolescents, adults, older adults and include new specific recommendations for pregnant and postpartum women and people living with chronic conditions or disability. All adults should undertake 150–300 min of moderate-intensity, or 75–150 min of vigorous-intensity physical activity, or some equivalent combination of moderate-intensity and vigorous-intensity aerobic physical activity, per week. Among children and adolescents, an average of 60 min/day of moderate-to-vigorous intensity aerobic physical activity across the week provides health benefits. The guidelines recommend regular muscle-strengthening activity for all age groups. Additionally, reducing sedentary behaviours is recommended across all age groups and abilities, although evidence was insufficient to quantify a sedentary behaviour threshold. Conclusion These 2020 WHO guidelines update previous WHO recommendations released in 2010. They reaffirm messages that some physical activity is better than none, that more physical activity is better for optimal health outcomes and provide a new recommendation on reducing sedentary behaviours. These guidelines highlight the importance of regularly undertaking both aerobic and muscle strengthening activities and for the first time, there are specific recommendations for specific populations including for pregnant and postpartum women and people living with chronic conditions or disability. These guidelines should be used to inform national health policies aligned with the WHO Global Action Plan on Physical Activity 2018–2030 and to strengthen surveillance systems that track progress towards national and global targets.

              Sedentary behavior and health outcomes among older adults: a systematic review

              Background In the last decade, sedentary behavior has emerged as a new risk factor for health. The elderly spend most of their awake time in sedentary activities. Despite this high exposure, the impact of this sedentary behavior on the health of this population has not yet been reviewed. We systematically reviewed evidence for associations between sedentary behavior and multiple health outcomes in adults over 60 years of age. Methods We searched the Medline, Embase, Web of Science, SPORTDiscus, PsycINFO, CINAHL, LILLACS, and Sedentary Research Database for observational studies published up to May 2013. Additionally, we contacted members of the Sedentary Behaviour Research Network to identify articles that were potentially eligible. After inclusion, the methodological quality of the evidence was assessed in each study. Results We included 24 eligible articles in our systematic review, of which only 2 (8%) provided high-quality evidence. Greater sedentary time was related to an increased risk of all-cause mortality in the older adults. Some studies with a moderate quality of evidence indicated a relationship between sedentary behavior and metabolic syndrome, waist circumference, and overweightness/obesity. The findings for other outcomes such as mental health, renal cancer cells, and falls remain insufficient to draw conclusions. Conclusion This systematic review supports the relationship between sedentary behavior and mortality in older adults. Additional studies with high methodological quality are still needed to develop informed guidelines for addressing sedentary behavior in older adults.
