This study describes the establishment of the North American Male Reference Database for the Omnisense device.

Study Design
In this study the speed of sound (SOS) was measured at four skeletal sites in healthy North American Caucasian men, aged 20-90, with the Sunlight Omnisense™ 7000S. To establish the Omnisense reference database curve, 588 healthy Caucasian males (age range 20-90) were recruited.

Subjects
To be eligible for the study the subjects had to meet the following criteria:

• No history of osteoporotic fracture or chronic condition affecting bone metabolism.
• No exposure for more than a year within the preceding three years to medication affecting bone.

Results
SOS of all sites, except the tibia, increased to a peak between the ages of 42 and 46. Comparison to the female SOS demonstrates that the female SOS is higher from age 20 to 39, with a significant difference between male and female at the radius and phalanx. Between the ages of 45 and 59, the radius, phalanx, and metatarsal SOS declines in females at a greater rate than in males. The reference curves cross at around 60 years of age. Female SOS remains lower than male SOS for the remainder of life at the radius, phalanx, and metatarsal.

Male and Female Reference Database SOS as Measured at the Radius

Conclusion
This study established the reference curves for male SOS in North America, to be used for the calculation of Z-scores with the Sunlight Omnisense 7000S bone sonometer. Omnisense™ is the only QUS device today that provides a male reference data base.

"As president, I have committed my company to providing medical facilities with "state-of-the-art" bone densitometry equipment to help them do a better job with preventing, testing for, screening for, detecting, diagnosing, and treating Osteoporosis which ravage so many women and men. Our diagnostic equipment will speed up the prevention, detection, diagnosis, and treatment of Osteoporosis and osteoporotic bone disorders in men and women. The key to preventing Osteoporosis in women and men is early detection, diagnosis, and treatment. This means measuring, testing, screening, detecting, and diagnosing low bone mass in women and men early in their lifetimes so that effective treatment can stop the Osteoporosis dead in its tracks." Together, we can help protect families from this terrible disease.

Sincerely,
Mark Piening
