The Role of Blood Groups in Health Anxiety, Marital Adjustment, and Quality of Life in Nurses

Background: This study aimed to determine the effect of blood groups on dyadic adjustment, quality of life, and health anxiety in nurses. Methods: In this causal-comparative research, 200 married nurses working in the health care centers of Iranshahr City were selected by simple random sampling using Cochran's sample size formula in 2019. Data were collected using Spinner's marital adjustment questionnaire, War and Sherborn's quality of life questionnaire, and Salkovskis' health anxiety inventory. Results: To investigate the difference among the groups, SPSS was applied, and multivariate and one-way analyses of variance were run. Among the subscales of dyadic adjustment, only the mean score of dyadic cohesion was higher in blood group A than in groups B and AB. Among the subscales of life quality, the mean score of affective role play was higher in blood group A than in groups B and AB, the mean score of social function was lower in blood group B than in blood group O, and the mean score of general health was higher in blood group A than in group B. However, the mean score of health anxiety was lower in blood group A than in blood group B. Conclusions: Given the relationship between health anxiety, marital compatibility, and quality of life with blood types among married nurses, the present study results can help increase people's awareness about at-risk blood types. As a result, vulnerable groups can be screened and trained to improve their lifestyles, healthy behavior, and environment to live a better life.
