Pattanayak, S. K., Blitstein, J. L., Yang, J. C., Dickinson, K., Patil, S. R., Poulos, C., & Wendland, K. M. (2007). Promoting Latrine Use and Improving Child Health: Design and Baseline Findings from a Randomized Evaluation of a Community Mobilization Campaign in Bhadrak, Orissa.
Objective: To present the study design and baseline findings of a randomized controlled intervention to decrease child morbidity and mortality associated with diarrhea by increasing the demand for and use of individual household latrines in the state of Orissa, India.
Design: Cluster-randomized controlled trial with repeated measures on households. The sample included 40 representative villages from a sampling frame of 1112 villages in the district of Bhadrak. Under random assignment, 20 villages received an intensive community social mobilization (CLTS) campaign and the remaining villages served as controls. Data collection from approximately 25 households per village was secured through the use of local enumerators trained by our research staff. Across the 40 villages, 1086 households (treatment = 534, control = 552) were surveyed; the same set of households will be surveyed post-intervention.
Setting: Chandbali and Tihidi blocks, Bhadrak district, Orissa India, 2005.
Participants: Respondents who self-identified as the primary care giver of a child below the age of 5 years provided data for the household survey. Key informants (i.e., village elders, teachers) provided information on village infrastructure and characteristics.
Results: Baseline findings suggest that randomization successfully distributed potential confounders across experimental conditions; some differences across condition are identified and these will be controlled for analytically in the impact analyses.
Conclusions: The Orissa evaluation will provide important information on the effectiveness of information and education campaign efforts to alter the demand for individual household latrines and promote household and community sanitation and hygiene practices.
