*

Notes: Number of deprivations based on the sum of deprivations in education (none or incomplete primary education), income (household income < US $150 dollars per month) and assets (lowest tertile of possessions weighted asset index) in the same individual;

**

Those with two or more deprivations were considered socioeconomically deprived;

***

All individuals that smoked in the last 30 days qualified as current smokers;

****

The difference between current smokers and those who reported cigarette consumption in the last 30 days is accounted for those who reported having smoked in the last 6 months but not in the last 30 days.
