The aims of this study are as follows: (1) To assess the existing level of knowledge regarding prevention of selected respiratory diseases among cement factory workers (2) To determine the effectiveness of structured teaching program on knowledge regarding prevention of selected respiratory diseases among cement factory workers and (3) To find out the association between post-test knowledge scores regarding prevention of selected respiratory diseases with their selected socio demographic variables. This was a pre-experimental, i.e. one group pre-test post test design was adopted for the present study. The sample includes 50 cement factory workers from E.S.I. dispensary at Bagalkot, Using simple random probability sampling technique. Data collected using structured knowledge questionnaire & analyzed using descriptive and inferential statistics. The mean percentage of knowledge scores of cement factory workers in pre-test knowledge was 44.2 % score (17.68±4.310). Whereas the mean percentage of knowledge scores in post-test was 84.15% of total score with mean and SD (33.66±3.42).Further effectiveness was tested using the paired ‘t’ test showed the significant difference in the knowledge of cement factory workers regarding prevention of selected respiratory diseases after the administration of STP (t49=20.52, p<0.05). A finding reveals that there is No significant association between post-test knowledge scores of the cement factory workers with socio demographic variable. There was significant difference was found between the pre-test and post-test knowledge of cement factory workers after the administration of STP. Therefore study showed that STP was highly effective in improving the knowledge of cement factory workers on prevention of selected respiratory diseases.
