Summary Objective Low 25‐hydroxyvitamin D (25OHD) levels may be associated with both
sarcopenia (the age‐related decline in muscle mass and function) and low physical activity
(PA). Our objective was to describe prospective associations between 25OHD, muscle
parameters, and PA in community‐dwelling older adults. Design Prospective, population‐
based study with a mean follow‐up of 2· 6±0· 4 years. Patients Six hundred and eighty‐six
community‐dwelling older adults (49% women; mean±SD 62±7 years old). Measurements …

A prospective study of the associations between 25hydroxyvitamin D, sarcopenia
progression and physical activity in older adults … In the present paper, Scott et al. claim
that muscle vitamin D status may have implications for sarcopenia progression, a notion that
we strongly support. However, we failed to spot data on sarcopenia prevalence or incidence
and wonder whether the authors defined sarcopenia for the context of this study. This may
be important, as much debate currently exists in this regard.The European consensus on …
