Background: Early marriage is one of the most important social issues for young women, which can have many consequences. Therefore the present study aimed to explore the consequences of early marriage among Kurdish women in western Iran.Methods: This qualitative study was conducted with the approach of conventional content analysis among Iranian Kurdish women who were married under the age of 18. The data were saturated through semi-structured interviews with 30 women selected by purposeful sampling. Data analysis was performed by Graneheim and Lundman’s method.Results: A total of 389 codes, 12 subcategories, 4 sub-categories, and 2 main categories were extracted from data analysis. Negative consequences of early marriage include 1- Physical and psychological problems (high-risk pregnancy and childbirth, physical illnesses, depression, and emotional distress), 2- Family problems (dissatisfaction with married life, Experience of having lots of responsibility, lack of independence in family life), 3. Social problems (social deviance, deprivation of social and health services, social isolation, deprivation of job, and educational opportunities) and positive consequences include receiving intra- family support, improving living conditions, and opportunities for progress and empowerment.Conclusions: It is possible to reduce problems and challenges after early marriage by increasing the awareness and knowledge of young women about contraceptives, providing appropriate social and health facilities and services during pregnancy. Providing the necessary training and psychological counseling for them and their husbands on how to deal with personal problems and marital life will be effective to a great extent.
