title: Analyzing sociodemographic factors amongst blood donors.
abstract: BACKGROUND
  Blood transfusion is a fundamental and requisite part of any National Health Service for optimum management of emergency conditions like severe trauma shock and resuscitation with the optimum stock of its different components. The objective of the present study was to analyze the factors of knowledge of prospective blood donors that may influence their perception and awareness about blood donation.
  
  
  METHODS
  This population-based cross-sectional study was conducted at Gangtok in the state of Sikkim, India, on 300 subjects of the adult population selected by two-stage cluster sampling. The main outcome variables were the socioeconomic and demographic variables of knowledge of blood donation. By interview technique, using the pre-tested structured close-ended questionnaire, the principal investigator collected the data.
  
  
  RESULTS
  In our study population, 46% of the study population was found to have a high knowledge score. The knowledge about blood donation was found to be statistically significant with the occupational status and the education levels, both in the bivariate and in the multivariate analyses. Knowledge about blood donation was not significantly related to age, sex, marital status, religion, community status and per capita monthly family income.
  
  
  CONCLUSIONS
  The study suggested that the perceptions toward voluntary blood donation could be influenced to a large extent by sociodemographic variables of knowledge among the general population.
