FIGURE 1—

Relative frequency (percentage of all reasons given) with which different factors are cited in reviewed articles as influencing adoption of (a) insecticide treated nets, (b) point-of-use water treatments, and (c) improved biomass cookstoves.

Note. Data are manually coded from the results of a PubMed query on adoption behavior. The search yielded 1105 articles (from the years 1985 to 2010), of which 175 were ultimately found to be relevant to adoption of insecticide-treated bed nets, 28 to adoption of household water treatments, and 7 to adoption of improved biomass stoves. (Relative to the other two technologies, it is only relatively recently that improved cookstoves have been rigorously evaluated as a health intervention, explaining the significantly smaller sample of articles.)
