Background:

To examine the relationship between body composition and disabling foot pain as assessed by the Manchester Foot Pain and Disability Index (MFPDI).

Methods:

137 subjects aged 25–62 years were recruited as part of a study examining the relationship between obesity and musculoskeletal health. Disabling foot pain was determined from the MFPDI and defined as current foot pain and pain in the last month, and recording >= 1 disability item on the MFPDI (an MFPDI score of >= 1). Body composition was measured using dual x-ray absorptiometry.

Results:

The BMI in this population was normally distributed around a mean of 32.2 kg/m2.The prevalence of foot pain was 54.7%. In multivariate modelling, there was a positive association between BMI and disabling foot pain (OR 1.11, 95% CI 1.05, 1.17). Similarly, the risk of disabling foot pain was positively associated with total body fat mass (OR 1.05, 95% CI 1.02, 1.08) adjusted for age, gender, strenuous physical activity, and skeletal muscle mass. Total body fat mass was also positively associated with functional limitation, foot pain intensity and self consciousness regarding feet/footwear, independent of skeletal muscle mass.

Conclusions:

Fat mass, but not muscle mass, is associated with foot pain. This suggests that obesity may affect foot pain not only through increased loading but also act via a systemic mechanism through increased adiposity. Further work is needed to clarify the mechanisms for this effect and the importance of reducing body fat rather than simple weight loss in the reduction of foot pain.
