title: Possible relationship among socio-economic determinants, knowledge and practices on lymphatic filariasis and implication for disease elimination in India.
abstract: OBJECTIVE
  To assess the socio-economic determinants, knowledge and practices on lymphatic filariasis in India and discuss the implications for elimination.
  
  
  METHODS
  A case-control study was undertaken to obtain knowledge and practice measures on various dimensions of the Wuchereria bancroftian filarial disease using a structured questionnaire. A structural equation model, a statistical technique for testing and estimating causal relationships using a combination of statistical data and qualitative causal assumptions, was developed.
  
  
  RESULTS
  Among the affected individuals, the model was able to explain more than 90% of the variance in awareness about the lymphatic filariasis, 58% of the variance in prevention aspects of the disease and 24% of the variance in people's knowledge about mosquitoes. The corresponding values in non-infected individuals were 49, 24 and 34%, respectively. A significant positive effect of education on awareness and prevention aspects of the disease was noted among the non-infected individuals. However, among the affected individuals, the awareness on various aspects of the disease was completely absent.
  
  
  CONCLUSIONS
  The present analysis highlights the crucial role played by formal education on creating awareness about lymphatic filariasis and how to prevent this vector-borne disease. The importance of education on intervention measures against mosquito breeding and biting is also dealt with in the analysis for planning an effective and sustainable control program.
