Summary
Greenland Eskimos exhibit significantly lower serum calcium levels, likely due to low dietary calcium intake, not vitamin D deficiency. This may contribute to the early onset of osteoporosis in this population.
Area of Science:
- Nutritional Science
- Bone Health Research
- Epidemiology
Background:
- Serum calcium levels vary significantly between populations and geographic locations.
- High vitamin D levels are observed in Canadian Eskimos, suggesting vitamin D sufficiency.
- Osteoporosis is prevalent among Arctic Eskimo populations.
Purpose of the Study:
- To investigate the reasons for low serum calcium levels in Greenland Eskimos.
- To explore the relationship between serum calcium, vitamin D, diet, and osteoporosis in Greenland Eskimos.
- To compare serum calcium levels in Greenland Eskimos residing in Greenland versus Denmark.
Main Methods:
- Comparative analysis of serum calcium levels.
- Assessment of vitamin D levels.
- Evaluation of dietary calcium intake, including dairy consumption.
- Correlation analysis with osteoporosis prevalence.
Main Results:
- Greenland Eskimos in Greenland have significantly lower serum calcium than Greenland Eskimos and Danes in Denmark.
- Danes in Greenland show intermediate serum calcium levels.
- High vitamin D levels were noted in Canadian Eskimos, and high serum calcium in Greenland Eskimos in Denmark, particularly adolescents with high dairy intake.
Conclusions:
- Low dietary calcium intake is the probable cause of low serum calcium in Greenland Eskimos.
- Low serum calcium may predispose Greenland Eskimos to early-onset osteoporosis.
- Dietary factors, specifically calcium, play a crucial role in bone health in this population.
