Malnutrition is a major threat to the health of HIV infected individuals and is associated withrnincreased risks of morbidity and mortality.rnObjective; the objective of the study was to assess the nutritional status and associated factorsrnamong adolescents living with HIV enrolled at public hospitals in Addis Ababa, Ethiopia.rnMethods: Facility based across-sectional study was conducted between February and Aprilrn2016.Data were collected on 340 adolescents aged 10-19 years attending government publicrnhospitals in Addis Ababa.rnNutritional status was assessed using BMI-for-Age (BAZ) and Height-for-age (HAZ) asrnmeasures of thinness and stunting respectively. Standard deviation (SD) scores (Z scores) werernapplied to determine the nutritional status. Adolescents whose BAZ and HAZ was less than -3SDrnwere considered severely malnourished; those adolescent with BAZ and HAZ between -2SD andrn-3SD were considered malnourished while those with BAZ and HAZ >= - 2SD were wellnourished.rnStatistical analysis was done using WHO anthro plus and STATA 12. Statisticalrnsoftware package.rnResult: The prevalence of stunting was 37.4% [0.3218-0.425, 95% CI, with 8.2% [0.052-rn0.11, 95% CI] of adolescents being severely stunted.rnThe risk factors for stunting included skipping of meal [(AOR: 1.74.; 95% CI:1.07- 2.83) andrnprimary care (AOR: 1.23.; 95% CI, 1.03.-1.47). The prevalence of thinness was 15.6 % [0.117-rn0.194, 95%CI] with 2.9% [0.0113 - 0 .047, 95% CI] severely thin. The risk factors for thinnessrninclude treatment interruption [AOR 2.78, 95% CI, 1.20- 6.43] nutrition counseling[AOR 2.05rn,95 %CI,1.13- 3.72 ] and moderately household food insecurity (AORAOR1.67,95CI % 1.21-rn3.21) amongadolescentsliving with the HIV enrolled at public hospitals in Addis Ababa,rnEthiopia.rnConclusion:The prevalence of stunting and thinness was high among the HIV infectedrnadolescents. Skipping meal, getting primary care from relatives, nutritional counseling, andrnmoderately household food insecurity were significantly associated with malnutrition (stuntingrnand thinness).rnRecommendation; Greater recognition of the substantial burden of malnutrition amongrnadolescents living with HIV is needed, and there is a need for more services aimed at nutritionrncounseling, retention in care , nutrition interventions beyond clinical settings and economicrnempowerments of adolescents living with HIV.rnKey words; HIV, thinness, stunting, adolescents
