Summary
This cross-sectional cohort emphasized the impact of heel bone mass in the South Indian population and its comparison with Nigerian ethnicity, residing in South India. Peak bone mass, however, evidenced a significant decrease of around 30% compared to that of Nigerian ethnicity.
Introduction
In the South Indian population, the local folks do not seem to be well informed about the relative association of bone mass with osteoporosis. Hence, there is an acute necessity to assess the same with respect to the ethnic population, presumed to have possessed high bone mass, i.e., the Nigerian population.
Methods
The calcaneus of the right foot was measured with a quantitative ultrasound device (Sahara, Hologic Inc., USA) for a total population of 734, out of which 314 were Indian males, 348 Indian females, 41 Nigerian males, and 30 Nigerian females, whose ages ranged from 18 to 35 years.
Results
The peak bone mass in Indian males and females is 0.507 ± 0.1 and 0.479 ± 0.1 g cm−2, respectively, and it is 0.714 ± 0.2 and 0.682 ± 0.2 g cm−2 with regard to Nigerian male and female populations, respectively. Indian males and females who were within the age group of 26–30 and ≤20 years, respectively, represented high bone mass, and the same was the situation with respect to Nigerian counterparts who were within the age group of 21–25 years. Indian and Nigerian non-vegetarian population of both the genders demonstrated a high significance value of p < 0.000001, deciphered by means of unpaired t test.
Conclusion
Peak bone strength was dominant in the Nigerian population compared to that of Indians. The Indian population is approximately lagging by 28–30% with respect to peak bone mass behind their Nigerian equivalents. Indian non-vegetarian male and female populations lagged by 6.15% and 6.16% behind the Indian vegetarian male and female populations, respectively.
