This study observed the relationship between television consumption and child obesity through the theoretical construct of Putnam’s displacement hypothesis. It did so by updating the previous research through the investigation of the displacement of both physical activity and advertisements on contemporary television platforms. The inclusion of Putnam’s displacement hypothesis was to provide a foundational framework, not found in previous literature, to study two important paradigms that were represented in previous research: 1) the displacement of physical activity; and 2) the displacement of traditional advertisement exposure.

Several trends became apparent within previous literature. Previous literature did not include an explicitly stated …

INTRODUCTION: According to the National Institute of Health consensus, Osteoporosis causes premature disability in approximately 44 million people (National Institute of Health [NIH], 2001), 80% of this population being women (Ulrich, Georgiou, Gillis, & Snow, 1999). This chronic disease causes 1.5 million fractures annually, 700,000 occurring at the spine (NIH, 2001). One prevention technique developed in recent years is to build a high peak bone mass during growth and in young adult life (Almstedt, Canepa, Ramirez, & Shoepe, 2011). Several publications positively correlate an increase in BMD with increased amounts of exercise. Bone mineral density can be observed through DEXA …
