Back.round: Termination of p.egnancy (TOp. in Zambia is.guided by the Termination of p.egnancy (TOp. Act of 1972 and as.amended in 1994 of the laws.of Zambia. However, des.1}te p.ovis.on of Comp.ehens.ve abortion care s.rvices.with the liberal law, s.atis.ics.at k.nyama Firs. Level Hos.1}tal in relation to uns.fe illegal abortions.are alarming.

The s.udy s.rveyed 370 randomly s.mp.ed women aged 15 to 49 years.old while the in-dep.h interviews.included eight women p.rp.s.vely s.mp.ed from the s.rvey p.p.lation. s.rvey data was.analyzed us.ng des.rip.ive and inferential s.atis.ics.while qualitative data thematic analys.s.was.us.d. Res.lts. The s.udy found that 37% of the p.rticip.nts.were aware of the TOp.Act while 63.8% viewed legalization of abortion for any reas.n as.wrong.
