It is anticipated that the demand for contraceptives in Iran will increase in the near future as the number of women of reproductive age increases and with women wanting smaller families. The aim of this paper was to study the demand for long-acting and permanent contraceptive methods (LAPCMs), and its determinants, among Kurdish women in Mahabad city, Iran. Data were taken from the Mahabad Fertility Survey (MFS) conducted on a sample of over 700 households in April 2012. The results show that the demand for LAPCMs was 71.35% at the time of survey, although only 27.7% of women were using these methods. Thus, the number of unintended pregnancies is likely to increase in the future if this gap is not reduced. The multivariate analysis showed significant impacts on the dependent variables of the number of children ever born, perceived contraceptive costs and childbearing intentions. Moreover, women at the end of their reproductive lives and those with higher education were more likely to desire LAPCMs. It is concluded that despite a growing use of contraceptive methods in Iran in recent decades, the development of reproductive health services and promotion of the quality of family planning services remains a necessity.
