Serum selenium levels in healthy Yugoslavian children and adults were analyzed. While age and location did not impact selenium status, significant differences were observed between genders in children and between children and adults.

Area of Science:

Clinical Chemistry
Human Nutrition
Trace Element Analysis

Background:

Selenium is an essential trace element vital for human health.
Understanding selenium status is crucial for assessing nutritional health and potential deficiencies.
Geographical and demographic factors can influence trace element levels in populations.

Purpose of the Study:

To determine serum selenium concentrations in healthy children and adults in Yugoslavia.
To investigate the influence of age, sex, and geographic region on serum selenium levels.
To compare selenium status between pediatric and adult populations.

Main Methods:

Atomic absorption spectrophotometry was employed for precise serum selenium quantification.
Serum samples were collected from 86 healthy individuals (63 children, 23 adults).

Statistical analyses were performed to assess variations based on age, sex, and region.

Main Results:

Mean serum selenium in children was 57 ± 9 µg/L, with significant differences between boys and girls (P < 0.05).
Mean serum selenium in adults was 69 ± 18 µg/L, with no age-related variations.
Adults exhibited significantly higher serum selenium levels than children (P < 0.05).

Conclusions:

Serum selenium levels in healthy Yugoslavian individuals vary by sex in children and between age groups.
Geographic location and age did not significantly affect selenium status in the studied populations.
The findings highlight the importance of considering demographic factors in selenium status assessments.
