The Dussb survey collected data from 800 heads of households (adults). A probabilistic type sampling by two-stage survey (multi-stage survey) was carried out. We proceeded by a simple random sampling of the EA (Enumeration Area) at the 1st degree. Four (4) EAs were drawn in each district. In total, forty (40) EAs were drawn at random in all nine (09) neighborhoods of the District of Moungali (District of Moungali). Then, a random choice of 20 plots was made in each EA (cluster) to reach a total sample of 800 plots. Only one household was interviewed in each plot, for a total of 800 households (adults). However, seventy-eight household heads had incomplete data. The minimum size of our sample was calculated using Daniel Schwartz's formula: k n = minimum size of our sample; k=cluster effect=2; z= parameter linked to the risk of error, set at 0.05 and corresponding to 1.96 in the table of reduced deviations; i= desired absolute precision (i=0.05); Pproportion=0.5; ; q=1-P. Observations with unspecified age and other incomplete variables were excluded from the database, thus reducing the size of our sample to 722 heads of household for this alcohol study.
