The millennium development goal (MDG 5) of reducing maternal mortality by three quartersrnbetween 1990 and 2015 is highly related with poor women 's nutritional stalus. Poor malernalrnnutrition is directly associaled wilh mOlher's resistance to infeclion or malernal ill heallh duringrnpregnancy and child birth. Therefore providing obstetric care alone is nol going 10 be enoughrnsolution for Ihe problem, unless olherwise poor women 's nutritional stalus is resolved. In depthrnunderstanding women's nulritional slalus is therefore crucial in any attempl 10 allain Ihe goal ofrnreducing malernal mortality level and food security. In this regard, Ihis study examines thernlevels, differentials and determinants of malnutrition among women in Ethiopia.rnThe main purpose of Ihe study is to assess the levels, socio-economic and demographicrndifferentials and to analyse their determinants. The paper uses the large data set from the 2005rnEthiopian demographic and health survey on 4080 non pregnant and non lactaling women agedrn15-49 in rural and urban parts of the country. Women 's body mass index (Kg/m2) is used for thernpurpose of analysing women's nutrilional stalus and those wilh BMI value less than 18.5 are atrnrisk of chronic energy deficiency (eED). Logistic regression model was employed at multivariaternanalysis to idenlifY importanl delerminant factors of women's malnulrition.rnThe silidy reveals that 27. 6 percenl of Ihe women are malnourished of which 23.1 percent arernmoderalely and 4.5 percenl are severely deprived. Levels were almost 2 times higher in ruralrnareas than urban areas. The study identifies women's age, parity, currenl marilal stalus, place ofrnresidence, region, house hold economic slatus, occupation and women decision makingrnall/onomyas imporlanl factors in explaining Ihe varialion in women's nulri/ional sla/us. In ruralrnareas non educaled women in Ihe age group 15-19 and 45-49, living in regions Tigray,GambellarnAmhara Ben-shangul Gumuz and Somali are found /0 be under nourished. In urban areasrnwhere as never married and divorced women, wilh poor and velY poor household economicrnslalus living in regions Tigray and Gambella are al risk.rnHence 10 improve Ihe silualion Ihe Policy should focus on crealing mechanisms andrnopporlunilies to increase agricullural produclion and women's educalion as well as providingrnbeller access 10 heallh care, particularly, in rural
