Um die negativen Auswirkungen von langem #Sitzen zu kompensieren, empfehlen #Wissenschaftler etwa 30-40 Minuten tägliche #Bewegung mit moderater bis intensiver Intensität. Aktivitäten wie zügiges Gehen, #Radfahren oder #Gartenarbeit können das Risiko vorzeitiger #Todesfälle durch #Bewegungsmangel senken. Diese Erkenntnisse stammen aus einer Meta-Analyse, die Daten von über 44.000 Personen auswertete.

British Journal of Sports Medicine · Joint associations of accelerometer-measured physical activity and sedentary time with all-cause mortality: a harmonised meta-analysis in more than 44 000 middle-aged and older individualsObjectives To examine the joint associations of accelerometer-measured physical activity and sedentary time with all-cause mortality. Methods We conducted a harmonised meta-analysis including nine prospective cohort studies from four countries. 44 370 men and women were followed for 4.0 to 14.5 years during which 3451 participants died (7.8% mortality rate). Associations between different combinations of moderate-to-vigorous intensity physical activity (MVPA) and sedentary time were analysed at study level using Cox proportional hazards regression analysis and summarised using random effects meta-analysis. Results Across cohorts, the average time spent sedentary ranged from 8.5 hours/day to 10.5 hours/day and 8 min/day to 35 min/day for MVPA. Compared with the referent group (highest physical activity/lowest sedentary time), the risk of death increased with lower levels of MVPA and greater amounts of sedentary time. Among those in the highest third of MVPA, the risk of death was not statistically different from the referent for those in the middle (16%; 95% CI 0.87% to 1.54%) and highest (40%; 95% CI 0.87% to 2.26%) thirds of sedentary time. Those in the lowest third of MVPA had a greater risk of death in all combinations with sedentary time; 65% (95% CI 1.25% to 2.19%), 65% (95% CI 1.24% to 2.21%) and 263% (95% CI 1.93% to 3.57%), respectively. Conclusion Higher sedentary time is associated with higher mortality in less active individuals when measured by accelerometry. About 30–40 min of MVPA per day attenuate the association between sedentary time and risk of death, which is lower than previous estimates from self-reported data.

BioMed CentralAssociation of daily sitting time and coffee consumption with the risk of all-cause and cardiovascular disease mortality among US adults - BMC Public HealthBackground Sedentary behavior has been demonstrated to be a modifiable factor for several chronic diseases, while coffee consumption is believed to be beneficial for health. However, the joint associations of daily sitting time and coffee consumption with mortality remains poorly understood. This study aimed to evaluate the independent and joint associations of daily sitting time and coffee intakes with mortality from all-cause and cardiovascular disease (CVD) among US adults. Methods An analysis of a prospective cohort from the 2007–2018 National Health and Nutrition Examination Survey of US adults (n = 10,639). Data on mortality were compiled from interview and physical examination data until December 31, 2019. Daily sitting time was self-reported. Coffee beverages were from the 24-hour diet recall interview. The main outcomes of the study were all-cause and cardiovascular disease mortality. The adjusted hazard ratios [HRs] and 95% confidence intervals [CI] were imputed by Cox proportional hazards regression. Results Among 10,639 participants in the study cohort, there were 945 deaths, 284 of whom died of CVD during the follow-up period of up to 13 years. Multivariable models showed that sitting more than 8 h/d was associated with higher risks of all-cause (HR, 1.46; 95% CI, 1.17–1.81) and CVD (HR, 1.79; 95% CI, 1.21–2.66) mortality, compared with those sitting for less than 4 h/d. People with the highest quartile of coffee consumption were observed for the reduced risks of both all-cause (HR, 0.67; 95% CI, 0.54–0.84) and CVD (HR, 0.46; 95% CI, 0.30–0.69) mortality compared with non-coffee consumers. Notably, joint analyses firstly showed that non-coffee drinkers who sat six hours or more per day were 1.58 (95% CI, 1.25–1.99) times more likely to die of all causes than coffee drinkers sitting for less than six hours per day, indicating that the association of sedentary with increased mortality was only observed among adults with no coffee consumption but not among those who had coffee intake. Conclusions This study identified that sedentary behavior for more than 6 h/d accompanied with non-coffee consumption, were strongly associated with the increased risk of mortality from all-cause and CVD.

»Es ist also gar nicht die Position, die beim #Sitzen so ungesund ist, sondern der Fakt, dass man sich dabei zu wenig bewegt?
- Genau. Das Problem ist, dass man beim Sitzen einen sehr geringen Energieverbrauch hat. Nach der Definition gilt also Liegen, etwa vor dem Fernseher, als sitzendes Verhalten. Nach der WHO-Definition ist ein Mensch körperlich inaktiv, wenn er weniger als 150 Minuten pro Woche moderat bis heftig in Bewegung ist.«

Eine aktuelle Erhebung der Krankenkassen belegt: Wir sitzen uns durchs Leben. Durchschnittlich 9,2 Stunden sitzen die Deutschen am Tag.

Was gemütlich klingt, ist für den Körper Gift und begünstigt Rückenschmerzen, Bluthochdruck und Diabetes.
Bewegung als Ausgleich ist wichtig. 🪑🏋

#Gesundheit #Bewegungsmangel #Sitzen - Ab wann wird Sitzenbleiben zum Gesundheitsrisiko? - "Früher legten Menschen hunderte Kilometer zu Fuß zurück, heute sitzen wir im Schnitt neun Stunden täglich auf Bürostühlen und Sofas. Welche Gesundheitsrisiken das Dauersitzen birgt – und wie man diese verringern kann." - Interessanter Beitrag von Frederik Jötten - Eventl. € spektrum.de/news/bewegungsmang
