Abstract
This study examined the influence of cultural, religious, and gender-related factors on modern contraceptive use among married women in Garbatula sub-county, Isiolo County, Kenya. Using a cross-sectional design, data were collected from 300 married women aged 15-49 years through multistage random sampling. Data were analyzed using descriptive statistics, chi-square tests, and binary logistic regression. Findings showed that reduced religious influence (AOR = 13.918; 95%CI : 2.54-76.30), male involvement in reproductive decision-making (AOR = 7.765; 95%CI : 2.30-26.23), and higher women's empowerment (AOR = 4.322) were strong positive predictors of modern contraceptive use, whereas rigid cultural norms and patriarchal attitudes were significant barriers. The study concludes that contraceptive behavior in pastoralist settings is shaped by religious and gender norms rather than access alone. It recommends engaging religious leaders, strengthening male-centered family planning education, and integrating gender-sensitive strategies within the County Integrated Development Plan (CIDP) to enhance uptake.
