Objective: Health literacy improves self-regulation and management of diabetes through proper diets in diabetic men. As a result, they will gain more knowledge about the effects of this disease on marital life and sexual relationships. The present study aimed to investigate the relationship between women’s marital intimacy with sexual satisfaction and health literacy among husbands with diabetes.
