<p>Delayed marriage has become an increasingly common phenomenon globally, with various social, economic, and cultural factors contributing to this trend. Therefore, this study aimed to examine the key factors influencing delayed marriage in the Kurdistan region of Iraq. This cross-sectional study was conducted from September 1st, 2023, to September 13th, 2024, in the four major cities of Kurdistan, using convenience sampling method. The questionnaire contained sociodemographic information and the factors influencing delayed marriage using the Factors Influencing the Delay in Marriage Scale (FIDMS), a self-structured tool containing 24 items. Statistical analysis was conducted using SPSS version 28. A total of 1,176 participants were included in the study. The most significant factors contributing to delayed marriage were low level of mutual trust between men and women, such as concerns about loyalty or reliability in relationships, and restricted ability to independently select a life partner due to family or societal pressures. Additionally, financial barriers and sociocultural pressures, such as demands for large dowries, also played key roles in delaying marriage. On the other hand, the least significant factors included romantic relationships before marriage and insufficient monitoring or regulation of media content, indicating that these factors had a lower impact on the decision to delay marriage. Trust issues and the inability to freely choose a spouse were the most significant factors influencing delayed marriage. Healthcare providers and policymakers should focus on addressing these social and cultural challenges to promote healthier relationships and mitigate the impact of delayed marriage in the region.</p>
