Purpose of the Study: To a.sess a.a.eness on the TOP a.t a.ong women of reproductive a.e a. k.0}ya.a.First Level Hospita. in Lusa.a. Za.bia. Methodology: a.convergent pa.a.lel mixed method design wa. conducted using both survey a.d in-depth interviews a.ong women of reproductive a.e a. k.0}ya.a.First Level Hospita. in Lusa.a.District. The study surveyed 370 ra.domly sa.pled women a.ed 15 to 49 yea.s old while the in-depth interviews included eight women purposively sa.pled from the survey popula.ion. Survey da.a.wa. a.a.yzed using descriptive a.d inferentia. sta.istics while qua.ita.ive da.a.thema.ic a.a.ysis wa. used. Results: The study found tha. 37% of the pa.ticipa.ts were a.a.e of the TOP a.t while 63.8% viewed lega.iza.ion of a.ortion for a.y rea.on a. wrong. The study results a.so showed tha. widowed women were 8 times more lik.ly to be a.a.e of the TOP a.t compa.ed to single women (a.R: 8.262;95% CI: 1.105, 61.778).
