Although all the kids in the intervention colleges and grades were subjected to the intervention program, written consent from parents and assent from children were necessary for any data collection. The study was accepted by the institutional review board at each participating university. Recruitment procedures22 were similar for the intervention and control schools. Intervention The intervention contains four integrated components: nutrition, exercise, behavioral knowledge and skills, and communications and social advertising.

Neither non-impact activity nor medium-impact activity was predictive of improved risk, but each whole hour of high-influence activity increased the chance of pressure fracture by approximately 8 %. Older age in the beginning of a girl’s menstrual period also increased the chance of developing stress fracture. Each one-year delay in onset of menstruation was connected with an approximate 30 % increase in risk. Becoming underweight, over weight and engaging in disordered eating were not associated with the threat of developing stress fracture. ‘Our study observed that high effect activities, specifically basketball, running and gymnastics/cheerleading, significantly boost risk for tension fracture among adolescent women.Neither non-impact activity nor medium-impact activity was predictive of improved risk, but each whole hour of high-influence activity increased the chance of pressure fracture by approximately 8 %.
