Abstract
Background Modern contraception plays a vital role in family planning and preventing unintended pregnancies. However, its uptake remains limited in many developing countries, including Pakistan. This study aimed to evaluate the barriers to modern contraception and identify strategies to enhance its adoption in the urban slums of Karachi. Methods A multi-site, cross-sectional study was conducted in 38 slum areas of Karachi, Pakistan. Women aged 15-49 years were interviewed using a comprehensive questionnaire. The questionnaire covered socio-ethnic and economic demographics, knowledge and perceptions of modern contraception, accessibility, affordability, attitudes, and usage. Data analysis was performed using the Statistical Package for Social Sciences (SPSS) version 24 (IBM SPSS Statistics, Armonk, NY). Results The majority of the respondents identified as Pathan ethnicity (49%), and the age range was predominantly from 23 to 34 years (45.5%). A high proportion of participants demonstrated satisfactory knowledge of contraceptives (87.6%). However, a significant portion perceived contraception or family planning to be in conflict with religious beliefs (84%). Many women expressed a desire for more children (56%) and had concerns about contraceptive side effects (78%). A notable proportion of women reported that their spouses forbade the use of contraceptives (12%). Among the surveyed population, the most widely used contraceptives were injections among women (15.5%) and condoms among their male partners (12%). Conclusion Despite sufficient knowledge and accessibility, considerable barriers exist in the uptake of modern contraception in the urban slums of Karachi, Pakistan. These barriers include religious conflicts, cultural norms, concerns about side effects, spousal disapproval, and desires for larger families.
