Conducted from August 1995 to June 1997, HUNT2 constituted both a new cross-sectional survey and a follow-up of HUNT1. The scientific programme was extended to include several large public health issues in accordance with current national health priorities. These were cardiovascular disease (CVD), diabetes, obstructive lung disease, osteoporosis, headache, mental health, chronic musculoskeletal pain and urinary incontinence. In addition to questionnaires, interviews and clinical examinations, the participants contributed with blood samples for instant analysis and storage. A total of 65 237 participated in HUNT2 (69.5% of those invited).*
