:: Data Collection
At baseline, year 3 (for participants 40-60), year 5 and year 10, a long questionnaire was administered to all consenting participants. 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.
