One strategy of the implementation of the family planning program stated in the Medium Term Development Plan in 2004-2009 was the increasing use of the long-term contraceptive method (LTM) such as the intra uterine device (IUD). IUD is one type of long term contraceptives that is ideal in order to space pregnancies. This study aimed to determine the factors associated with the selections of IUDs for family planning acceptors in Jailolo Health Center. This was a cross sectional design. The population was all active family planning acceptors in Jailolo Health Center. Sampling was done by using simple random sampling. Data were processed by using univariate, bivariate, and multivariate tests, analyzed with SPSS Ver.20 and chi-square with a significance of α = 0.05. The results showed that based on the bivariate analysis there was a relationship between the variables of age, education, knowledge, service rates, partner approval, and culture with the selection of IUD; while job, economic status, and service rates showed no relationship with the selection of an IUD at the Jailolo Health Center. Multivariate analysis of five related independent variables showed that education was the most dominant in the selection of IUD with P = 0.161. Conclusion: among the active family planning acceptors in Jailolo Health Center from December 27, 2012 until January 19, 2013, age, education, knowledge, service rate, partner approval, and culture were related to the selections of IUDs; and education was the most dominant one.
