Beauchet O et al. - Low serum 25-hydroxyvitamin D (25OHD) concentrations were associated with high stride-to-stride variability of stride time (STV) reflecting a disturbed gait control. This association could be explained by a possible action of vitamin D on different components involved in gait control.
Methods
- 411 community-dwelling older adults (mean age 70.4 ± 1.8 years, 57.9% women)
- STV and 25OHD concentration assessed
- The following established 25OHD thresholds were used:
- severe 25OHD insufficiency <10 ng/mL
- moderate 10–30 ng/mL
- normal >30 ng/mL
- Age, number of drugs used per day, use of psychoactive drugs, depressive symptoms, cognitive decline, history of falls, distance visual acuity, lower limb proprioception, center of mass (CoM) motion, and walking speed were considered as potential confounders.
