Background: Determinants of family planning (FP) use were studied in multiple researches. Strong associations were recognized between FP use and some socio-demographic, sociocultural and socio-economic characteristics. Aim: to identify determinants of FP use and other factors that may influence FP use and decision making. Methods: Secondary analysis of data from the Egypt Demographic Health Survey (EDHS) 2000 and 2008. Pearson's Chi-square (χ2), two sample t test and regression analyses were performed. Results: The contraceptive prevalence rate in 2000 & 2008 was 48.5% & 51.6 % respectively. The significant predictors of FP use in both EDHS were; participant age, residence, husband education and desire for more children. FP use was steadily increasing with the increase of respondent’s education from 42.9% to 56.4%. Partner’s education significantly influenced FP use; it increased from 40.6% to 56.8%. FP decision was determined by; respondent’s age, education, work & place of residence, and partner’s education in both surveys. Conclusion: Respondents' age, work, & education, husbands' education, and contact with healthcare workers were FP &fertility determinants, therefore we recommend stopping early marriage, encouraging education for girls and boys, improving the outreach services, and empowering women with more work opportunities.
