Program to Prevent Osteoporosis in Girls

Study Overview
=================
Brief Summary
-----------------
Osteoporosis is a condition defined by decreased bone mass. Osteoporosis generally affects older women and can lead to bone fractures. One way to prevent osteoporosis is to build strong, healthy bones during childhood. This study will evaluate a program designed to improve girls' bones. The program encourages eating foods rich in calcium and participating in physical activity.

Detailed Description
-----------------
Osteoporosis affects more than 25 million people in the United States. The majority of bone fractures in older women are related to osteoporosis. Calcium intake and physical activity are two modifiable behaviors associated with peak bone mass. Interventions targeting these behaviors among youth have tremendous public health potential for preventing osteoporosis. This study will assess the feasibility and effectiveness of a 2-year behavioral program designed to increase calcium intake and physical activity among girls ages 9 to 11. Thirty Girl Scout troops will be recruited for the study. Girls will be randomized either to the eating and exercise behavior change program or to a control group. Program components focus on behavioral skills development, goal setting, and self-monitoring for dietary calcium intake and physical activity. The program also works to increase social support from peers and parents. The program will take place during 10 weeks of both the 5th and 6th grade years. The program also includes supporting programs during winter and summer breaks. Outcome assessments will be conducted at baseline, and at 6, 12, and 24 months. Primary outcomes will include dietary calcium intake, physical activity, and bone mineral density.
