The mission of the MRC Lifecourse Epidemiology Centre is to use lifecourse epidemiological methods to reduce the population burden of chronic musculoskeletal disease and disability.
Musculoskeletal disorders constitute a major public health problem: the Global Burden of Disease study estimates that the category imposes the second highest impact on years of life lived with disability, and is set to rise by over 40% by 2050.1 The costs associated with these conditions are equivalent to 3% of gross national product each year. Indeed osteoporosis and osteoarthritis (the most common metabolic bone and joint disorders respectively) account for 6.8% of total disability with a remaining lifetime risk of osteoporotic fractures at the hip, wrist or spine of 39% among women and 13% among men at age 50 years;2 the annual NHS cost of managing osteoporotic fractures is £4.2 billion, half of which is attributable to hip fracture.1 From age 50 years, lifetime risks of total knee arthroplasty (representing end-stage osteoarthritis) are 10.8% for women and 8.1% for men.3 Sarcopenia, the commonest muscle disorder worldwide, is estimated to cost £2.2 billion in the UK each year.4
The purpose of our research is to elucidate important, preventable causes of these common non-communicable musculoskeletal disorders and their complications. Through an understanding of the causes of these disorders, and the development and evaluation of interventions at appropriate stages in the lifecourse, we aim to provide robust and timely evidence which informs policies to improve population and individual health.
