This study indicated that more than half, 338(57.5%) of the participants had received PNC services with confidence interval of (53.4–61.6).
The utilization of postnatal care service in this study is lower than a study done in Bahi District, Tanzania 70.8% . The possible explanation for this difference may be due to social context variation.
This result is also lower than the previous Ethiopian studies: Addis Ababa, 65.6% , Gondar Zuria District, 66.83%  and Adwa town 78.3% . The possible explanation for this difference might be due to those communities with a low concentration of educated and poor women lead to the lower attention of the need for postnatal care service utilization. The other suggestion might be due to sample size determination differences. Lastly it might be due to lack of information about postnatal care, low maternal knowledge about danger signs of postnatal care and low attention of health professionals in counseling the women to came back for postnatal care.
According to this study the utilization of postnatal care service is higher than a study conducted in rural area of Western Rajasthan, India 35.86% , Nepal 43.2% , Palestine 36.6% , Soroti district Eastern Uganda 15.4% , Africa 36%  developing countries 36% , a study done in four Sub-Saharan African countries: Burkina Faso 25%, Kenya 33%, Malawi 41% and Mozambique 40% .The possible reason to the discrepancies might be due to cultural differences, time differences of study socioeconomic status, geographical factors, heterogeneity of study population and political concern of governments. The other possible explanation for the difference might be due to the unique nature of Ethiopia utilizing health extension workers.
This finding is also higher than the 2016 EDHS national and Amhara regional report .The possible reason for this difference may be the study area where EDHS included both women who lives in urban and rural areas of the country while our study includes only urban residents. Hence, women who live in urban areas are at a greater advantage of getting education opportunity and maternal health care services. Additionally, women in the urban areas may get easy access to health facility and health professionals as compared to their counterparts.
Postnatal care utilization of this study is higher than the research carried out in Sidama zone (Southern Ethiopia) 37.2% , Debre Markos town 33.5% , Abuna Gindeberet District, Oromiya 31.7% ,Hadiya zone, South Ethiopia 22.7% , Dembecha District 34.8% , baseline and end line postnatal care surveys in Amhara and Oromia region , Jabitena district, Amhara regional state, 20.2%  and Lemo Woreda 51.4% .This difference may be due to time difference between these studies, socioeconomic status, and cultural factor. The Other possible explanation for these differences may be increased governmental focuses from year to year in order to improve maternal and neonatal healths.
According to this study, the odds of PNC service utilization among women with secondary school and above by education were 3 times than those who couldn’t read and write. This finding is consistent with the study done in Nepal , Cambodia , rural area of Western Rajasthan, India , developing countries , Africa , Nigeria , Bahi District, Tanzania , rural India , Entoto Fana health center, Addis Ababa , rural Haramaya District, Eastern Ethiopia , southern Ethiopia , Abi-Adi Town, Tigray , Jabitena district, Amhara region  and Dembecha District, North West Ethiopia .The possible reasons for this similarity might be due to the fact that once a women is educated, her autonomy and decision making skill on her health and maternal health care services utilization is high .Similarly, uneducated mothers have no chance to participate in different social and economic positions, decision making and women’s empowerment. Additionally, education helps to increase mothers’ level of awareness and their acceptance of new idea and provides better education to other women regarding postnatal care services utilization.
In the present study, the odds of PNC service utilization among women with monthly income greater than 1500 ETB were 2.8 times than those who earn less than 500 ETB. This finding is consistent with a study done in developing countries , Rwanda , Nigeria , Tanzania , India , Nepal  and Addis Ababa, Ethiopia .
The possible suggestion for this might be women having better monthly income can afford for all expenses like for transportation.
The analysis also showed that, the odds of PNC service utilization among women with alive birth outcome were 5.7 times than those who gave still birth. This is in line with a study done in Debre Markos town . The possible reason for this similarity may be good birth outcome might have better insight in postnatal care service utilization.
This study also showed that, the odds of PNC service utilization among women with desire of pregnancy were 4 times than those whose pregnancy was unplanned and unsupported. This finding is supported by a study done in three rural districts of Tanzania  and California .
This study also revealed that the odds of PNC service utilization among women who gave birth at health facility were 3 times than those who delivered at home. This finding is consistent with a study done in three rural districts of Tanzania , Rwanda , Nigeria , Tanzania , Nepal , Addis Ababa, Ethiopia , Hadiya zone, South Ethiopia , Debre Markos town , Lemo Woreda, Ethiopia  and another study done in Jabitena district, Amhara region .The possible explanation for the similarity between place of delivery and postnatal care services utilization can be evidenced by women who gave birth in health institutions have better opportunity to receive health education related to postnatal care services, get access on benefits and availabilities of PNC services during their stay in health facilities.
Limitation of the study
There could be recall bias since the women were asked for events within the last one year prior to the study. On the other hand the study did not include the rural population which is restricting the scope and relevance. Lastly, since the the design is quantitative it doesn’t address cultural issues of the respondents.
