The aim of the study was to assess exposure to indoor air pollution at a household level and find out the feasibility of using questionnaire in determining exposure level for indoor air pollution . Cross sectional study design was utilized . Data were collected using structured questionnaire , in-depth interview with key informants and child movement recording . Data entry and analysis was done using Epi Info version 6 statistical software . A total of 600 households f rom the three study areas (rural high land , rural lowland and t own)were assessed . Three hundred thirty four(55 . 7%)of the households had high exposure level to indoor smoke Rural households were less likely to have adequate smoke clearance compared to urban households (OR=O . 3 ; 95% CI=O . 16 , 0 . 54) . Being muslem, married , Mother illiterate and and low economic status were less likely to be in the low exposure status with adjusted OR(95%CI) of 2 . 24(1.39 , 3 . 54) , 0 . 41(0 . 18 , 0 . 82) , 0 . 36(0 . 2 , 0 . 66)and 0 . 34(0 . 22 , O ~4) , respectively . The main source of indoor Hlnoke was biomass fuel used by 98 . 5% for cooking and 29 . 6% for heating . The majority (94.9%) were using open type of stove without flue or chimney . The median (SO) of exposure time by the interview and observation was found to be 180(202) and 125(148) minutes ,respectively. From this we conclude and recommend that biomass fuels are the principal sources for the indoor smoke , the poor socio- demographic and environmental factors expose children to indoor smoke and collecting information about exposure time of under five children using interview and observation methods has no statistically significant difference . Using cleaner fuels , improving social , economic , cultural and environmental conditions could improve the exposure level to indoor smoke .enSmoke ,PollutionThesis
