Abstract
This study aimed to investigate the relationship between bone mineral
density (BMD) and digit ratio, with the goal of evaluating the potential of
digit ratio as a marker for predicting osteoporosis-type bone diseases. The
study sample included 200 patients (100 women and 100 men) who visited
the Nuclear Medicine Clinic at Cumhuriyet University Research Hospital
for check-ups, along with a control group of 100 healthy individuals (50
women and 50 men). Bone densitometry measurements were obtained for
all participants, and the lengths of the second and fourth digits on both
hands were measured using digital calipers. The results indicated a positive
correlation between digit ratio and BMD, with this relationship being more
pronounced in women. In men, significant positive correlations were
found between the right-hand digit ratio and L BMD (r = 0.589), the right
digit ratio and L T-score (r = 0.544), and the right digit ratio and L Z-score
(r = 0.454). Similar positive associations were observed between the right
digit ratio and femoral BMD (r = 0.608), femoral T-score (r = 0.465),
and femoral Z-score (r = 0.362) (p < 0.05). For women, stronger positive
correlations were identified between the right-hand digit ratio and L BMD
(r = 0.707), the right digit ratio and L T-score (r = 0.815), and the right
digit ratio and L Z-score (r = 0.737). Additionally, significant associations
were noted between the right digit ratio and femoral BMD (r = 0.469),
femoral T-score (r = 0.535), and femoral Z-score (r = 0.495) (p < 0.05).
These findings suggest that the association between digit ratio and bone
mineral density is stronger in women. In summary, individuals with a high
digit ratio generally have higher bone density
