I would like to know how to proceed and the justication Mathematical and Statistical. My dependent variable is spent on health (0=No   1=Yes). The prevalence was higher than 10 percent. Can I do Poisson regression? According to this paper published in BMC on line in 2003, registred   PMC521200 I can do Poisson regression with variable (0=No  1=Yes) and with prevalence higher than 10 percent, but other authors report that only I can do Poisson regression with the dependent variable= discrete variable and prevalence under 10 percent. 
Which is correct? And what is the explanation Mathematical and Statistical?Thanks, Alexandra
