Methods. A prospective observational study included 131 adults (mean age 43.35 ± 16.37 years; 54.2 % women). Anxiety and depression were assessed using the GAD-7 and PHQ-9 scales. Homocysteine levels were quantified by LC-MS. Group comparisons and odds ratios (OR, 95 % CI) were calculated; p < 0.05 was considered statistically significant. Results. Elevated homocysteine levels (≥ 10 μmol/L) were detected in 50.4 % of participants, while concentrations > 15 μmol/L were observed in 11.5 %. Homocysteine levels were approximately two-fold higher in individuals with clinically significant symptoms compared with those with subclinical manifestations (anxiety: 13.98 ± 4.50 vs 6.88 ± 2.08; depression: 13.92 ± 4.43 vs 6.87 ± 2.05; p < 0.001). Homocysteine ≥ 10 μmol/L was strongly associated with clinically significant anxiety (OR = 157.5; 95 % CI 33.4–741.6; p < 0.001) and depression (OR = 320.0; 95 % CI 40.0–2557.8; p < 0.001). Conclusions. Hyperhomocysteinemia was common among individuals exposed to prolonged war-related stress and closely associated with the severity of anxiety and depression. Elevated homocysteine levels were identified in 50.4 % of the examined participants with ADDs, indicating a high prevalence of disturbances in one-carbon metabolism. A dose-dependent relationship between homocysteine concentration and ADDs severity was observed. Increased homocysteine levels were associated with a higher probability of clinically significant anxiety (58 %) and depressive disorders (64 %). These findings support the pathogenetic role of hyperhomocysteinemia in stress-associated ADDs and justify the use of homocysteine as a biomarker of risk, severity, and prognosis of anxiety-phobic and affective disorders.
