Reviewer's report:  
 
Thank you for the opportunity to re -review this important manuscript. The authors have 
thoroughly revised the manuscript and have adequately addressed my prior concerns. I would 
like to r aise some additional considerations for the authors in regard to their revised 
multivariable analyses:  
1. Please provide justification for the variable selection for the multivariable model in the 
statistical analysis section of the Methods. Were variables  selected for the multivariable 
model based on the outcomes of univariate analyses, extant literature, or some kind of 
forward or backward selection for model building?  
2. It is possible for collinearity to exist between some of the variables included in the model. 
How did the authors assess the potential for collinearity?  
3. The discussion section would be strengthened by incorporating the multivariable 
findings. Based on the multivariable findings, the authors may consider providing some 
guidance in rega rd to high -priority groups to target with future research and educational 
interventions (e.g., younger women, urban women who do not use condoms and who are 
low income).   
 
Are the methods appropriate and well described?  
If not, please specify what is required in your comments to the authors.
