Chromium status of the aged
Summary
This study found that plasma chromium levels in older adults did not correlate with cholesterol or blood glucose. Chromium levels also showed no consistent link to age or sex in the elderly.
Area of Science:
- Biochemistry
- Gerontology
- Nutritional Science
Background:
- Chromium is an essential trace element involved in carbohydrate and lipid metabolism.
- Age-related changes in chromium levels and their metabolic implications are not fully understood.
Purpose of the Study:
- To investigate the relationship between plasma chromium levels and key metabolic markers in the aged population.
- To determine if age or sex influences plasma chromium concentrations.
Main Methods:
- Blood samples were collected from an aged cohort.
- Plasma chromium concentrations were measured.
- Statistical analyses were performed to assess correlations with serum cholesterol, fasting blood glucose, age, and sex.
Main Results:
- Plasma chromium levels in the aged ranged from 0.5 to 22.1 ng/ml.
- No significant relationship was observed between plasma chromium and serum cholesterol.
- No significant relationship was observed between plasma chromium and fasting blood glucose.
- Plasma chromium values did not show a consistent relationship with age.
- Plasma chromium levels were not affected by sex.
Conclusions:
- Plasma chromium levels in the elderly do not appear to be associated with serum cholesterol or fasting blood glucose.
- Age and sex do not demonstrate a consistent influence on plasma chromium levels in this population.
