OBJECTIVES: Previous research consistently indicates that children who engage in active school transport (AST) are more active than their peers who use motorized modes (car or bus). However, studies of the correlates of AST have been conducted predominantly in high-income countries and have yielded mixed findings. Using data from a heterogeneous sample of 12 country sites across the world, we investigated the correlates of AST in 9-11-year olds. METHODS: The analytical sample comprised 6555 children (53...

Accelerometry has become a mainstay approach for objectively monitoring children's physical activity and sedentary time in epidemiological studies. The magnitude of effort underlying successful data collection, management and treatment is prodigious and its complexity has been associated with increasingly diverse methodological choices that, while defensible relative to specific research questions, conspire to undermine the ability to compare results between studies. Although respecting widespread calls for best practices, it is also important to openly share tools and resources supporting potential improvements to research practice and study design, thus allowing others to replicate, further improve, and/or otherwise build on this foundation...

REVIEW
J G Granneman
The recent demonstration of active brown adipose tissue (BAT) in adult humans, along with the discovery of vast cellular and metabolic plasticity of adipocyte phenotypes, has given new hope of targeting adipose tissue for therapeutic benefit. Application of principles learned from the first wave of obesity-related BAT research, conducted 30 years earlier, suggests that the activity and/or mass of brown fat will need to be greatly expanded for it to significantly contribute to total energy expenditure. Although the thermogenic capacity of human brown fat is very modest, its presence often correlates with improved metabolic status, suggesting possible beneficial endocrine functions...

REVIEW

The thermogenic activity of brown adipose tissue (BAT) in the organism is tightly regulated through different processes, from short-term induction of uncoupling protein-1-mediated mitochondrial proton conductance to complex processes of BAT recruitment, and appearance of the beige/brite adipocytes in white adipose tissue (WAT), the so-called browning process. The sympathetic nervous system is classically recognized as the main mediator of BAT activation. However, novel factors capable of activating BAT through non-sympathetic mechanisms have been recently identified...

After a long drought caused by misjudged irrelevance to human biology, the research field of brown adipose tissue has seen a period of resurgence since 2009 when discoveries of brown fat in adults were reported. However, the molecular and physiological regulators of the different types of adipose tissues-white, beige or brown-are still far from being fully determined. Speakers of the morning session of the 16th Annual Symposium of the Université Laval's Chair in Obesity, a series interestingly launched in 1998 precisely on the topic of uncoupling proteins, presented past and recent findings on non-adrenergic signaling pathways-both upstream and downstream-regulating the metabolic and thermogenic activities of adipose tissue...

T J Bartness, V Ryu
Reports of brown-like adipocytes in traditionally white adipose tissue (WAT) depots occurred ~30 years ago, but interest in white adipocyte 'browning' only has gained attention more recently. We integrate some of what is known about the sympathetic nervous system (SNS) innervation of WAT and brown adipose tissue (BAT) with the few studies focusing on the sympathetic innervation of the so-called 'brite' or 'beige' adipocytes that appear when WAT sympathetic drive increases (for example, cold exposure and food deprivation)...
