I am trying to estimate which demographic variables are associated with smoking and alcohol drinking. The prevalence of smoking and alcohol drinking in the study sample (cross sectional study) are 15% and 2%, respectively. I am using modified Poisson regression to estimate the prevalence ratio. Based on the literature modified Poisson regression is recommended if the prevalence of the outcome >10%. Is this model still appropriate for to estimate the prevalence ratio to identify which demographic variables are associated with alcohol drinking, where the prevalence is 2%?
Many thanks for your help.
