Context: Sub Saharan African countries lag behind the rematmng of world inrncontraceptive prevalence rate (CPR). The level of unmetJor family planning is also highestrnfor the region. Being part of the region. Ethiopia is not an exception to this situation. It isrnevident that unmet need for family planning has many undesirable consequences. Amongrnother things. maternal morbidity and mortality. unwanted pregnancy which could end uprnwith unsafe abortion. and infant mortality are the most noted consequences of unmetrnneed. The ultimate goal of this study is to identify the socioeconomic. demographic andrnfamily planning program related causes of unmet need among currently married women ofrnreproductive age in Oromiya region. Bale zone. Goba Woreda. Moreover. the study wasrnaimed at assessing reasons for current and future non use of contraceptive methodsrnamong women with unmet need.rnMethod: A community based cross-sectional study design was employed to achieve thernstated objectives. Multi-stage stratified sampling and systematic random sampling werernused to select tile 827 women for interview. To analyze the data both bivariate andrnmultivariate techniques of data analysis were applied. Chi square test was employed tornsee association between each predictive and outcome variable. Logistic regreSSion is alsornfit to identify determinants of unmet need for contraception using Statistical Package forrnSocial Scientists (SPSS Ver.15). Qualitative data were also generated using FGD andrnpersonal interview with health worker to supplement and further interpret the results ofrnthe quantitative data.rnResults: The results indicate that majority of the respondents were rural residentsrn(55.3%). orthodox Christians (47%) with no formal education (58.5%). and only one thirdrn(33.1%) of them currently working. Oromo is the single most dominant (69.9%) ethnic grouprnamong the women. Substantial proportions (22.9%) of women were also found in the agerngroup 25-29 years. In terms of their dedared reproductive status the fecund. pregnant.rnamenorrheic and menopausal/in fecund constitute for 46.7%. 9.6%. 25.4% and 18.4%rnrespectively. Knowledge about family planning is found to be very high (92%) amongrnrespondents. More interestingly. 50.5% of the respondents know four and over methods ofrnfamily planning. With regard to spousal communication. half (49.5%) of the study subjectsrnnever discussed family planning with their husbands. Moreover. four fifth (79.1 %) andrngreater than three fifth (63.1%) of the respondents never discussed with health extensionrnworkers and never visited a healthfacility respectively.rnThe level of unmet need for contraception in the study area (i,e.32.5%) is almost doser tnrnthe national average (34%). Unmet need for spacing (17.3%) is slightly greater than unmetrnneed for limiting 115.2%). As it is evidenced elsewhere the level of unmet need is higherrnamong rural women than their urban counterparts (42.5% versus 20.3% respectively). Thernlogistic regression model depicts. among other variables. number of living children. spousalrncommunication. visit of a health facility. discussion with health extension workers. agernand ethnicity are determinants of unmet need.rnConclusion: Number of living children that women have increases the Weelmood of unmetrnneed among women. Conversely. discussion with health extension workers andrnhusbands. increasing age of women. and women's visit of health facility where familyrnplanning is integrated in to MCH reduce the chance of having unmet need among women.rnFinally. the study recommends that women in their lower reproductive age should be givenrntop priority. Moreover. MCH program should be expanded to areas where it is absent andrnfamily planning programmers should exert due effort to encourage males to discuss withrntheir wives about FP and take part in contraceptive use.
