Effectiveness of structured Behavior Change Communication methods in control of mosquito-borne diseases: A quasi-experimental study.

Behavior Change Communication (BCC) is evidence-based, theoretically supported and utilizes all opportunities for communication. Evidence reports BCC as a relevant tool for averting and controlling many forms of public health challenges. Through schools, many countries have shown health improvements via students and the community's exposure to behavior change messages. The study was planned with an aim of evaluating the effectiveness of mosquito-borne disease control measures implementation through BCC to adolescent school students in a Cantonment area, in North India. The present study was undertaken as a quasi-experimental study from April 2019 to March 2020. Of the 334 students enrolled in the school as per eligibility criteria, 315 were available during the initial assessment, and 288 were available throughout the study. For the evaluation of effectiveness of the BCC at household level, 200 households (100 intervention and 100 control) were selected. Students' knowledge about mosquito-borne diseases was the primary outcome measure. The difference in proportions was tested using the chi-square test. The difference in proportions for paired samples was tested using Mc Nemar's test. Proportion of students who gave correct responses significantly increased after intervention in post-test as compared to pre-test for most of the knowledge-related questions. The proportion of households with the availability of mosquito nets and self-reported use of mosquito nets was significantly high in intervention group as compared to control group post-intervention. BCC in the form of different intervention programs to adolescent school children was effective in improving the knowledge and attitude toward mosquito-borne diseases and also ensured less mosquito-genic environment in households.
