Reviewer's report:
The manuscript looks good and most, if not all, of the issues raised have been
addressed. However, I still have a couple of concerns as outlined below.
Abstract- Maybe you should consider reducing the introduction
Introduction is OK
Methods - I think the title on line 130 is study population and sampling
- Furthermore, your study setting was a district, which is vast. But you did not
give details of how the study participants were sampled i.e. did you divide the
population into clusters before doing a simple random sampling? Because
ideally, a simple random sampling is possible only when a sampling frame (a full
list of the population of the district) is available, which is difficult to obtain. 
- on statistical analysis, you mentioned some results of the analysis (VIF) which
ideally I think it not advisable. Here I think you should just state that if the VIF is
< 2 then you will .......
Results - on the respondent characteristics (line 208), you did not write the units
of age (years)
Discussion- OK
Conclusion - OK
