BACKGROUND: Participation in family planning (FP) among young women who have ever married is the spearhead in reducing the Total Fertility Rate in Papua Province. However, the percentage of FP use in Papua Province in Papua Province is still very low, at 74.88%. This study looks at the dominant factors that influence the low participation of ever married young women in FP programs in Papua Province. METHODS: This study is a cross-sectional study using data from the 2017 Indonesian Health Demographic Survey, conducted for ± 1 month. The sample in this study was 414 married young women in Papua Province in 2017. Data analysis in this study is the same way as multivariate analysis of risk factor models, which was processed using the STATA 12 application. RESULTS: The final result of the multivariate analysis in this study was the household expenditure group variable (OR was 1.89 with a 95% CI value: 1.75–1.92), place of residence (OR 1.75 with 95% CI: 1.70–1.90), and age at first sexual intercourse (OR 2.34 with 95% CI: 2.24–2.48). In contrast, the most dominant variable that affects the low participation in FP use among young women who have ever been married in this study is the age of first sexual intercourse. CONCLUSION: This study recommends the need for crosssectoral collaboration to socialize the Generation Planning (Genre) program in schools and universities in all corners of Papua Province.
