Serum zinc concentrations in Finns
Acta Medica Scandinavica
|January 1, 1978
Summary
Serum zinc levels in Finns vary by sex, age, and region. Geographic variations in serum zinc may correlate with soil composition and coronary heart disease incidence, though direct links are unproven.
Area of Science:
- Human physiology
- Environmental health
- Nutritional science
Background:
- Serum zinc is a critical trace element with potential links to health outcomes.
- Geographic variations in environmental factors may influence human nutrient levels.
- Finland's unique geology presents an opportunity to study environmental impacts on human health.
Purpose of the Study:
- To determine the mean serum zinc concentrations in a large Finnish population.
- To investigate factors influencing serum zinc levels, including demographics and geography.
- To explore potential statistical associations between serum zinc, soil composition, and coronary heart disease in Finland.
Main Methods:
- Serum zinc concentrations were measured in 1416 Finnish individuals aged 15 and above.
- Participants represented 18 distinct population groups across Finland.
- Statistical analyses were employed to identify correlations between serum zinc and various factors.
Main Results:
- Mean serum zinc was 12.7 mumol/l for men and 11.7 mumol/l for women.
- Significant variations in serum zinc were observed based on sex, age, fasting duration, time of day, and geographic location.
- Statistical links were found between serum zinc levels, soil/water element composition, and coronary heart disease incidence.
Conclusions:
- Serum zinc concentrations exhibit considerable variability within the Finnish population.
- Environmental factors, particularly soil composition, may play a role in modulating serum zinc levels.
- While statistical associations exist, causal relationships between soil composition, serum zinc, and coronary heart disease require further investigation.
