ASSOCIATION OF ABO BLOOD TYPES WITH PSYCHOLOGICAL TRAITS: A STUDY ON STRESS, ANXIETY, AND DEPRESSION

This study investigates the association between blood types (A+, B+, AB+, O+) and psychological traits (anxiety, depression, stress) among 120 male college students (aged 18-25) from degree college of physical education college in Amravati, Maharashtra, India. Using a cross-sectional design and purposive sampling (30 per group), the Anxiety, Depression, and Stress Scale (ADSS-BSPSA) measured symptoms via self-reported questionnaires. Data were analyzed with descriptive statistics and one-way ANOVA in SPSS. Results revealed a significant difference in anxiety levels (F=2.84, p=0.041), with AB+ showing the highest mean (6.87±3.16) compared to A+ (4.47±3.23; post-hoc p=0.045). No significant differences emerged for depression (F=0.999, p=0.396) or stress (F=0.290, p=0.833), despite AB+ having slightly higher means. Findings suggest AB+ blood type may elevate anxiety via ABO gene links to neurotransmitter pathways, while depression and stress appear driven by environmental and coping factors, not blood type. This highlights potential genetic influences on anxiety in young males.
