OBJECTIVES: To examine the potential contribution of lumbopelvic pain (LPP) severity in well-functioning older adults to poorer walking efficiency and endurance and gait speed and decline in these mobility parameters over one to five years. DESIGN: Longitudinal analysis of Baltimore Longitudinal Study of Aging data SETTING: National Institute on Aging, Clinical Research Unit, Baltimore, MD PARTICIPANTS: Well-functioning men and women aged 60 to 89 years (n=878). MEASUREMENTS: Interviewer-administered questionnaire ascertained reported presence and severity of back and/or hip pain in the preceding 12 months and reported walking ability including ease of walking one mile. Certified examiners assessed usual gait speed, the energetic cost of walking (VO(2)mL/kg/m) and time to walk 400m as quickly as possible. Covariates included sex, age, age-squared, race, height, weight, exercise and smoking. RESULTS: Overall, 31.4% had mild and 15.7% had moderate to severe LPP. In adjusted analyses, reported walking ability, endurance walk performance and energetic cost of walking were worse with increasing LPP severity (p |
