• 1.   Sedentary Lifestyle: Overview of Updated Evidence of Potential Health Risks

  National Library of Medicine
  https://www.ncbi.nlm.nih.gov/pmc/article...
  Summary:
  A sedentary lifestyle, characterized by long hours of sitting and low physical activity, is linked to significant health risks, including increased all-cause mortality, cardiovascular diseases, diabetes, cancer, and metabolic disturbances like dyslipidemia and hypertension. Despite the global prevalence of sedentary behaviors—averaging 7.7 to 8.3 hours daily in adults in the U.S. and South Korea—many remain unaware of the severe implications. These behaviors diminish lipoprotein lipase activity and impair glucose and lipid metabolism, leading to reduced insulin sensitivity and altered hormonal levels, which in turn increase the risk of hormone-related cancers. Moreover, sedentary habits contribute to musculoskeletal issues, mental health challenges like depression, and cognitive impairments. Therefore, integrating regular physical activity, breaking up long periods of sitting with movement, and optimizing active periods can mitigate these health risks, emphasizing the importance of both reducing sedentary time and enhancing physical activity levels.

• 3.   The Normalization of the “Active-Sedentary” Lifestyle in Spanish Youth

  Scientific Research
  https://www.scirp.org/html/2-2290203_482...
  Summary:
  The study "Normalization of the 'Active-Sedentary' Lifestyle in Spanish Youth" reveals a significant cultural shift towards sedentary behaviors among young Spaniards, despite being perceived as "active" due to engaging in various non-physical activities. It highlights a paradox where physical activity levels are not increasing correspondingly with the perception of being active. The research shows that young adults differentiate between being busy with multiple daily activities and genuinely engaging in physical activities and sports, which are essential for maintaining health. The study stresses the need for structural sports policies targeting the primary institutions of socialization like families, schools, and media to counteract this trend. It suggests that breaking the cycle of sedentary habits requires a holistic approach, emphasizing the importance of early socialization into physical activity to foster long-term health and well-being.
  
  

• 4.   Potential Effects on Mortality of Replacing Sedentary Time With Short Sedentary Bouts or Physical Activity: A National Cohort Study

  American Journal of Epidemiology | Oxford Academic

  Summary:
  The study titled "Potential Effects on Mortality of Replacing Sedentary Time With Short Sedentary Bouts or Physical Activity: A National Cohort Study" conducted by Keith M Diaz and others, published in the American Journal of Epidemiology in 2019, explored the health impacts of replacing sedentary behavior with physical activity. Using data from a national cohort of US adults, the study utilized isotemporal substitution techniques to analyze how replacing total sedentary time and prolonged sedentary bouts with light-intensity physical activity (LIPA) or moderate to vigorous physical activity (MVPA) affects all-cause mortality risk.
  
  Key findings include:
  
  Reduction in Mortality Risk: Replacing 30 minutes of total sedentary time with 30 minutes of LIPA was associated with a 17% reduction in mortality risk, and replacing it with MVPA resulted in a 35% reduction.
  Impact of Sedentary Bout Duration: Shortening prolonged sedentary bouts (defined in the study as sedentary periods lasting ≥30 minutes) with periods of LIPA or MVPA also showed beneficial associations with mortality risk, whereas simply replacing them with shorter sedentary bouts did not significantly impact mortality risk.
  Activity Levels and Mortality Benefits: The study also noted that the mortality benefits from replacing sedentary time with physical activity varied depending on an individual’s overall activity levels. Less-active adults gained more significant health benefits compared to those who were already more active.
  This study emphasizes the importance of not only increasing physical activity but also strategically reducing and interrupting sedentary time to improve health outcomes. It suggests that interventions aimed at reducing sedentary behavior should include promoting both light and more vigorous forms of physical activity, tailored to individual activity levels to maximize health benefits.
  
  

• 5.   Sedentary behaviour and disease risk

  BMC Public Health
  https://bmcpublichealth.biomedcentral.co...
  Summary:
  Sedentary behaviour, defined as waking time spent sitting or lying with low energy expenditure, has become widespread in modern society and is linked to the rise of various chronic diseases, such as type 2 diabetes, cardiovascular disease, and obesity. This paper highlights the current evidence and proposes topics for a BMC Public Health collection on "Sedentary Behaviour and Disease Risk."
  
  Key Points:
  Definition and Prevalence: Sedentary behaviour is distinguished from physical inactivity and is prevalent across different environments, occupying up to 80% of waking hours.
  
  Health Risks: Increased sedentary behaviour is associated with higher risks of chronic diseases and premature mortality. For instance, sitting for more than 9.5 hours a day significantly increases the risk of all-cause mortality.
  
  Research and Guidelines: While research on physical activity has been extensive, studies on sedentary behaviour are relatively new but growing. Recent global guidelines emphasize reducing sedentary time and replacing it with physical activity.
  
  Epidemiological Evidence: A dose-response relationship exists between sedentary time and mortality. Breaking prolonged sitting with light activities can improve cardiometabolic health.
  
  Interventions and Public Health: Effective interventions to reduce sedentary behaviour are needed. These should be multi-component and context-specific, addressing both individual and environmental factors. Successful examples include workplace interventions with adjustable desks.
  
  Future Directions: The collection seeks high-quality, multidisciplinary research on sedentary behaviour and chronic diseases, public awareness campaigns, and interventions tailored to various contexts and populations.
  
  This comprehensive overview underscores the importance of addressing sedentary behaviour to mitigate the risk of chronic diseases and improve public health outcomes.
  
  

• 6.   Study shows benefits of exercise dependent on hours spent sitting

  Summary:
  A comprehensive review titled "Physiology of Sedentary Behavior," published in Physiological Reviews, highlights the need to reduce sedentary time and increase physical activity for better health outcomes.
  
  Key Points:
  Interconnected Health Risks: Sedentary behavior is associated with health risks such as high blood pressure, increased body fat, poor vascular function, and elevated blood glucose and insulin levels.
  
  Holistic Approach: The review suggests that public health guidelines should go beyond promoting physical activity alone and should advocate for less sitting, more movement, and exercise.
  
  Influence of Sedentary Time: The health benefits of physical activity are diminished by prolonged sitting. For instance, a jog after a day of sitting provides fewer benefits due to the accumulated sedentary time.
  
  Practical Implications: Professor David Dunstan emphasizes the importance of incorporating the question "How much time do you spend sitting?" into discussions about physical activity with GPs and primary health providers. This approach can better identify health risks and guide interventions.
  
  Breaking Up Sitting Time: Regularly interrupting sitting time with movement can restart muscle activity and reduce health risks. The focus should be on reducing sitting time as a starting point for becoming more active.
  
  Health Care Practice: The review aims to embed an evidence-based risk identification matrix into health care practice, showing the inextricable link between physical activity and sedentary behavior and their combined impact on health.
  
  Overall, the study calls for a more integrated approach to health guidelines, emphasizing the reduction of sedentary behavior alongside increasing physical activity to mitigate health risks.
