Abstract

BACKGROUND: The World Health Organization recommends a minimum of 150 min of moderate intensity exercise per week or 75 min of strenuous activity weekly for adults. Younger hip fracture patients are often assumed less active than the general population, however, knowledge on physical activity (PA) and health-related quality of life (HRQoL) in younger hip fracture patients is limited.

OBJECTIVES: We aimed to 1) investigate the variation in pre-fracture PA for adult patients with hip fractures under the age of 60; and 2) to quantify the association with patient characteristics, including outcomes of HRQOL and handgrip strength.

DESIGN AND METHODS: A prospective multicenter cohort study of 207 adult hip fracture patients under 60 years admitted to four study hospitals from July 2015 to December 2018. Data was collected through medical records, questionnaires, physical tests and interviews. PA level was assessed using a validated questionnaire from the Swedish National Board of Health and Welfare, providing a total score from 3 to 19. A score ≥11 corresponds to fulfillment of the WHO recommendation for weekly PA. Handgrip strength was measured in kilograms using a handheld dynamometer following a standardized protocol. Recall pre-fracture HRQoL was assessed using the EQ-5D-3L questionnaire.

RESULTS: Fifty-nine percent had a PA score ≤10 out of these 46% had an ASA grade of 3 or 4, 38% had a BMI over 25 and 81% had a low energy fracture. A PA score ≤10 was associated with a lower HRQoL compared to those who had a PA score ≥11. PA score ≤10 points was associated with weaker hand grip strength and a worse health status (higher ASA-grade) p<0.001.

CONCLUSION: We found that close to two-thirds of the patients had a pre-fracture PA level below WHO recommendations. Being more active was associated with better handgrip strength, HRQoL, and ASA score. Our findings indicate that individuals under 60 years who sustain a hip fracture form a heterogeneous group, some severely comorbid and others highly active and seemingly healthy. This suggests a more nuanced approach to rehabilitation, as the more active patient might need a more individualized plan than the standard program can offer.
