Name:______________________________________________________________________ A Case of Osteoporosis Emma broke her wrist when she fell during track practice. This was the third time she had a bone fracture (break) so her doctor suggested that Emma get a bone density test. Emma was shocked to hear that the results of her bone density test showed that her bone density is lower than normal for a teenage girl. Emma’s doctor warned her that she is at increased risk for developing osteoporosis when she gets older. Emma’s grandfather has osteoporosis—very low bone density. His bones are very brittle and fracture easily. His stooped posture (head and neck bent forward) is due to small fractures in his neck and spine (backbone). He also has pain and difficulty walking due to a hip fracture that has been slow to heal. Because Emma has low bone density and has a family history of osteoporosis, the doctor recommended that she take a dietary supplement that contains calcium. He also recommended that she use the Internet or attend community programs to learn more about osteoporosis. 1. Read the Information Card 1: Key to Bone Models. Observe the two bone models— Normal Bone and Osteoporosis Bone. Do not open the bone models. 2. Compare the models of normal bone and osteoporosis bone.  Which contains the most calcium? ______________________________________________________________________  Which is most porous (has more empty spaces)? ______________________________________________________________________  Which is most dense? Hints: Density = mass/volume. ______________________________________________________________________ Copyright © 2017 by University of Rochester.

Use the Information Cards (1-8) and the Understanding Osteoporosis poster to evaluate these claims.  For the Information Card column, write the number of the card that provides evidence to support or refute (disprove) the claim.  For the Poster column, write the letter of the poster section that provides evidence to support or refute (disprove) the claim. Sources of Evidence Conclusion Osteoporosis Claims Information Card Poster True or False (card number) (section letter) A. Osteoporosis occurs when the body loses too much bone, makes too little bone, or both. B. High bone density at the end of childhood No evidence increases the risk for developing osteoporosis on poster later in life. C. People with osteoporosis have bones that are less dense (more porous) than normal bones. D. As bone density increases, bones become weaker and more likely to break. E. Osteoporosis increases the risk for bone fractures, particularly in the spine, wrist, arm, and hip. F. The FDA has evaluated the use of calcium No evidence supplements as a way to improve bone health. on poster G. Males do not need to worry about bone fractures caused by osteoporosis. H. Bone density tests can be used to diagnosis osteoporosis. I. Having a family member with osteoporosis increases the risk of osteoporosis. J. Weight bearing physical activity (e.g. walking or running) increases the risk of osteoporosis. K. The bones of someone with osteoporosis No evidence contain less calcium than the healthy bones. on poster L. Alcohol and smoking increase the risk of osteoporosis. M. Taking calcium supplements reduces the risk for bone fractures due to osteoporosis. Copyright © 2017 by University of Rochester. All rights reserved May be copied for classroom use 2 4. Write the letter of the claim that caused the most discussion for your team? __________ Explain why that claim caused the most discussion. _________________________________________________________________________ _________________________________________________________________________ _________________________________________________________________________ _________________________________________________________________________ 5. Should Emma and other teens take calcium supplements to prevent osteoporosis and bone fractures when they get older?
