With advancements in healthcare and public education, life expectancy is increasing and the prevalence of age related health conditions such as osteoporosis are rising. It is well known that children and adolescents who engage in healthy behaviors are more likely to carry those behaviors into adulthood. More specifically, children and adolescents who engage in weight bearing physical activity have higher bone density and are less likely to develop osteoporosis later in life. Furthermore, technology that measures daily physical activity is improving and individuals are interested in the amount of activity they and their children should participate in to remain healthy. The primary focus of this study was to quantify the association between pedometer-based physical activity and various measures of bone mass in adolescents. A secondary purpose of this investigation was to determine if adolescents who took at least 10,000 steps per day exhibited higher bone mass compared to those who took less than 10,000 steps per day.
