Best Bones Forever! is a national bone health campaign that encourages girls ages 9–14 to adopt healthy habits for bone growth and osteoporosis prevention. The campaign was created by the U.S. Department of Health and Human Services’ Office on Women’s Health (OWH) in 2009. The campaign uses popular language, bright colors and images, and energetic messages to express a focus on fun and friendship. Best Bones Forever! aims to improve girls’ bone health behaviors, which include eating foods with calcium and vitamin D and participating in regular physical activity.
