Commentary: considerations for use of racial/ethnic classification in etiologic research.

abstract：:Physical activity tends to decline from childhood into adulthood. Maintaining high levels of physical activity throughout life is therefore an important public health objective. Relatively little is known about changes in physical activity behavior over the life course, the domains of physical activity in which they o...
