Following is a response from Senior DHS Stata Specialist, Tom Pullum:

To account for variation across 6 regions, a fixed effects model would be preferable. A rule of thumb for random effects is that you have at least 30 cases at that level, i.e. at least 30 regions. For fixed effects, you only need to include something like "i.v024" on the right hand side of the model.
