Background: Despite national efforts to promote family planning, contraceptive nonacceptance remains high in India, particularly in urban slums. This study investigates the knowledge, attitudes, and practices influencing contraceptive use among married women of reproductive age in UHTC, Pardeshipura, Indore. Methods: A crosssectional study was conducted with 665 married women of reproductive age using a house-to-house survey. Simple random sampling was employed to select slum zones, and data were collected using a pre-designed and pre-tested proforma. Statistical analysis was conducted to identify associations between contraceptive use and demographic factors. Results:The contraceptive acceptance rate was 52.03%. Oral contraceptive pills were the most commonly used method (26.91%), followed by condoms (10.97%). Non-users (47.96%) cited barriers such as religious restrictions (15.49%), spousal disapproval (12.63%), and lack of knowledge (6.47%). Acceptance was significantly associated with literacy (p < 0.05), occupation (p < 0.001), and socioeconomic status (p < 0.05). Conclusion: Literacy status, socioeconomic-status and occupation were significantly associated with the use of contraceptives. Targeted educational initiatives and male involvement in family planning are needed to address cultural and informational barriers. Strengthening urban health systems is crucial for improving access to contraceptives.
