:: Data Collection

At baseline, year 3 (for participants 40-60), year 5, year 10 and year 16 (for participants 60-75), a long questionnaire was administered to all consenting participants. A follow up mailed questionnaire was completed annually. Self reported fractures were confirmed by medical report or hospital discharge.

Bone density was measured using DXA (dual-energy X-ray absorptiometry) at the lumbar spine and hip, and ultrasound of the shin and wrist were taken.

Participants aged 50 years and older have had radiographs taken of the thoracic and lumbar spine. Blood, urine and DNA samples have been collected from participants in some centers at baseline, year 5 and year 10 follow-up. At year 16 follow-up, the participants aged 60 to 75 had radiographs taken of the thoracic and lumbar spine. Blood and DNA samples were collected from all consenting participants.
