Official title
Lifestyle Changes to Increase Bone Density in Teen Girls
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Osteoporosis affects nearly half of all American women over age 50. During the teenage years, girls can increase bone growth to decrease their risk of osteoporosis later in life. This study will test whether girls can change their food intake and physical activity patterns in ways that will increase their bone growth during the mid-teen years.
