● Discuss any questions or concerns regarding medical treatment when appropriate (including estrogen re- placement therapy or bone- density prescription medication). ● Consider offering screenings at the worksite. Quantitative ultrasound is one such screening tool. It mea- sures the speed of sound in the bone (usually the heel) to assess bone density and strength. The most accurate test of BMD is con- sidered to be the dual-energy X- ray absorptiometry (DEXA). DEXA scans usually are still needed to confirm results from ultrasound and other tests.

Recommendation for most adults is 1,000–1,200 mg of elemental cal- cium. Calcium citrate is absorbed easily, but is more expensive than calcium car- bonate. ● Assist in establishing a program for regular, weight-bearing exercise at least 3 to 4 times a week and strength training exer- cises to prevent calcium loss and increase bone strength.
