Modern human environments are vastly different from those of our forebears. Rapidly advancing technology in transportation, communications, workplaces, and home entertainment confer a wealth of benefits, but increasingly come with costs to human health. Sedentary behavior—too much sitting as distinct from too little physical activity—contributes adversely to cardiometabolic health outcomes and premature mortality. Findings from observational epidemiology have been synthesized in meta-analyses, and evidence is now shifting into the realm of experimental trials with the aim of identifying novel mechanisms and potential causal relationships. We discuss recent observational and experimental evidence that makes a compelling case for reducing and breaking up prolonged sitting time in both the primary prevention and disease management contexts. We also highlight future research needs, the opportunities for developing targeted interventions, and the potential of population-wide initiatives designed to address too much sitting as a health risk.

A recent summary of the epidemiologic evidence for physical inactivity and health using a burden of disease approach. An estimated 9% of premature mortality across the world was attributed to physical inactivity (not meeting MVPA physical activity recommendations). These estimates were similar to smoking, and larger than estimates attributed to obesity.

Independent of potential confounders, including moderate-to-vigorous physical activity, detrimental associations of sedentary time with waist circumference, HDL cholesterol, C-reactive protein, triglycerides, insulin, Homeostasis Model Assessment (HOMA)-%B, and HOMA-%S were observed. Independent of potential confounders and sedentary time, breaks were beneficially associated with waist circumference and C-reactive protein.

This is the first meta-analysis of dose-response relationships between total daily sitting time and mortality risk. The association between sitting and all-cause mortality were found to be nonlinear—such that people with high sitting time (>7 hours/day) have even higher risk of death (hazard ratio 5% vs 2%).
Healy GN, Dunstan DW, Salmon J, et al. Breaks in sedentary time: beneficial associations with metabolic risk. Diabetes Care. 2008;31:661–6. This cross-sectional study showed that, independent of total sedentary time and moderate-to-vigorous-intensity activity time, increased breaks in sedentary time were beneficially associated with waist circumference, body mass index, triglycerides, and 2-hour plasma glucose.
Saunders TJ, Larouche R, Colley RC, et al. Acute sedentary behaviour and markers of cardiometabolic risk: a systematic review of intervention Studies. J Nutr Metab. 2012;2012:712435. This systematic review concluded that (acute) uninterrupted sedentary behavior results in rapid and deleterious changes in insulin sensitivity, glucose tolerance, and lipid levels in adults. While there was a paucity of studies looking at sitting per se, the authors identify important areas for future research.
Dunstan DW, Kingwell BA, Larsen R, et al. Breaking up prolonged sitting reduces postprandial glucose and insulin responses. Diabetes Care. 2012;35:976–83. This randomized crossover trial assessed the effect of breaking up 5 hours of prolonged unbroken sitting with intermittent bouts of light and moderate treadmill walking (2 minutes every 20 minutes) in overweight/obese inactive participants. The study showed similar reductions in postprandial glucose and insulin ‘area under the curve’ with both types of activity ‘break’ compared with prolonged sitting.

Holmstrup M, Fairchild T, Keslacy S, et al. Multiple short bouts of exercise over 12-h period reduce glucose excursions more than an energy-matched single bout of exercise. Metabolism. 2014;63:510–9. This was a small but well-controlled randomized crossover study of 12 hours duration in obese participants, using high frequency blood sampling. Hourly 5-minute bouts of exercise were compared with an energy-matched single (1 hour) session of exercise. The 5-minute bouts were more effective in reducing postprandial glucose excursions and insulin concentrations compared with the longer duration (beyond daily physical activity recommendations) exercise bout.

Peddie MC, Bone JL, Rehrer NJ, et al. Breaking prolonged sitting reduces postprandial glycemia in healthy, normal-weight adults: a randomized crossover trial. Am J Clin Nutr. 2013;98:358–66. This large randomized crossover trial investigated the effect of breaking up 9 hours of prolonged unbroken sitting with intermittent bouts of treadmill walking (1:40 minute every 30 minutes) vs a single 30-minute bout of walking in 70 normal-weight adults. Interestingly, regular activity bouts were more effective at reducing postprandial glucose and insulin than was a single continuous bout of physical activity.

This review summarizes the data over the last 60 years on the metabolic adaptations to bed rest in healthy participants. The authors assert that physical inactivity may promote the concomitant development of insulin resistance, impairments in lipid trafficking, alterations in substrate utilization, and increased deposition of intracellular lipid. They also postulate that sedentary behaviors may promote metabolic inflexibility—a hypothesis of great relevance to metabolic disorders such as obesity and T2D.
