Consistent correlations have been found between physical dysfunctional states and blood factors. Some of these disorders have possible psychosomatic components (eg, duodenal ulcer, myocardial infarction). This study focused on the relationship between blood types and various indices of behavior patterns (eg, type A behavior scores, anger ratings) in young patients who had had an initial myocardial infarction. Patients with blood type O scored significantly higher on type A behavior scales and related indices than those having blood type A. Those with blood group B responded on several scales between those with types A and O. We discuss the utility of blood groupings in future research in the prediction of myocardial infarction, methodologic limitations, the relationship of these results to temperament studies, Jenkins Activity Survey subtest patterns, anti-H reactivity pattern, and hypotheses relating blood factors and behavioral traits in patients with psychosomatic disorders.
Neuroses and ABO blood types.
Neuropsychobiology 1983;9(1):16-18 Rinieris P, Rabavilas A, Lykouras E, Stefanis C
Determination of ABO blood types was carried out in 72 (35 female and 37 male) patients with obsessive-compulsive neurosis, 73 (35 female and 38 male) patients with phobic neurosis, 75 (54 female and 21 male) patients with hysteria and a random sample of 600 individuals (268 female and 332 male) drawn from the general population. Results provide evidence of: (1) a positive association between obsessive-compulsive neurosis and blood type A and a corresponding negative association between the former and blood type O; (2) a positive association between phobic neurosis and blood type O and a corresponding negative association between the former and blood type A, and (3) a positive association between hysteria and blood type A and a corresponding negative association between the former and blood type O. Moreover, sex does not appear to modify the ABO blood type distribution in our patients with obsessive-compulsive neurosis, phobic neurosis or hysteria. These findings might be considered as supporting the view that hereditary factors in the neurotic individual may influence the clinical form of his neurosis.
Influence of ABO blood type on symptomatology among outpatients: study and replication.
Boyer WF Neuropsychobiology 1986;16(1):43-46
Two independent samples of psychiatric outpatients (n = 52 and 60) with blood type A or O completed the Brief Symptom Inventory, an abbreviated version of the SCL-90. In both samples patients with blood type A scored significantly higher than those with type O on the 'Obsessive-Compulsive' and 'Psychoticism' factors. These findings are not attributable to differences in age, sex or diagnosis, and are consistent with several previous studies. The influence of blood type on symptom expression may be mediated by cell membrane characteristics.
Obsessive-compulsive neurosis, anancastic symptomatology and ABO blood types.
Rinieris PM, Stefanis CN, Rabavilas AD, Vaidakis NM Acta Psychiatr Scand 1978 May;57(5):377-381
Determinations of ABO blood types was carried out in 38 patients with obsessive-compulsive neurosis, 48 schizophrenics with anancastic symptomatology, 31 depressives with anancastic symptomatology, 260 schizophrenics free of anancastic symptomatology and 65 depressives free of anancastic symptomatology. Results were compared with a representative sample of the general population. The findings of the present study provide evidence of an association between obsessive-compulsive neurosis and phenotype A, whilst a similar association between ABO blood types and anancastic symptomatology occurring in the course of psychotic disorders was not found. The significance of these findings is discussed with regard to current diagnostic and aetiological issues in obsessive-compulsive neurosis.
Study on relationship between human ABO blood groups and type A behavior pattern.
Hua Hsi I Ko Ta Hsueh Hsueh Pao 1991 Mar;22(1):93-96. Mao X, Xu M, Mu S, Ma Y, He M
Investigation of the relationship between ABO blood groups (ABO BG) and Type A behavior pattern (TABP) was performed. CH and TH + CH scores in individuals with blood type A and type A personality were significantly lower (P less than 0.01). The values of TH-CH scores among tested people were of no statistical significance (P greater than 0.05). Moreover, nearly half of the examinees (41.32%) had higher CH score and the distribution of the individuals was obviously different in statistics (P less than 0.005). In addition, L score of examinees with blood type A and type B personality was relatively lower.
