Erythrocyte and Plasma Fatty Acid Profiles by Age Group in a German Clinical Cohort

1277 patients from a metabolic disease clinic in Brandenburg, Germany, had their plasma and erythrocyte fatty acid profiles measured by gas chromatography. The cross-sectional study, authored by Yingqi Yu and last updated in April 2026, stratified participants into five age groups and found higher omega-3 and lower omega-6 levels in older individuals.

Use Cases

• Modeling age-related trends in polyunsaturated fatty acid (PUFA) levels based on the reported profiles.
• Analyzing proxy indices for desaturation and elongation enzyme activity based on the described fatty acid ratios.
• Investigating correlations between specific fatty acids like EPA, DHA, LA, and DGLA and age groups.
• Benchmarking clinical cohort lipid data against population norms based on the reported geographic and clinical setting.

Strengths

• Includes data from 1277 patients, providing a substantial clinical sample size.
• Profiles measured in two biological matrices (plasma and erythrocytes) for comparison.
• Participants are stratified into five distinct age groups for clear comparative analysis.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description notes a cross-sectional design and lack of key determinants like diet or genetics, limiting causal inference.
