Background Increasing life expectancy has brought public health concern about the increase in prevalence of disability in old age. Reducing the prevalence of disability in older age requires the identification of preventable or modifiable risk factors earlier in life. We have examined the relationship between lifestyle and other potential risk factors in men aged 40-59 years at screening and locomotor disability 12-14 years later to assess whether any of these factors have direct and independent roles in influencing disability in later life. Methods In 1978-1980, a longitudinal study of cardiovascular disease was initiated in 7735 men aged 40-59 years drawn from one general practice in each of 24 British towns. The present study concerns 5717 men, 88% of the surviving men who were available to follow-up (i.e. were registered with a GP and had an address) and who satisfactorily completed the disability section of a follow-up postal questionnaire in 1992 (Q92). The main endpoint from the questionnaire was locomotor disability based on self-reported inability in any one or more of the following : to get outdoors, walk 400 m, climb stairs, maintain balance, bend down, or straighten up. Results In the 5717 men (mean age 63 years) who provided information on disability status, 25.0% reported locomotor disability and the majority of these men recalled a doctor-diagnosed disease of which cardiovascular disease was most strongly associated with locomotor disability.
