n 2007 we conducted a sample survey in Laos. Of 18 provinces, we chose five as representative of the geographical strata of south (Attapeu, Savannakhet provinces), central (Vientiane Capital and Vientiane provinces), and northern Laos (Luang Nam Tha province). In one district we applied a two stage random sample procedure. At the first stage we randomly selected a village and at the second stage, households. Random numbers were used to select the villages from the list of villages per district and households from the list of households in the villages. We randomly chose one adult per household to be interviewed in the Lao language from among all present household members aged over 18. We randomly selected and enrolled 84 villages and an average of 14 households with one adult from each. A semistructured questionnaire examined knowledge and use of the coffee creamer with the Bear Brand logo.
Participants gave their informed consent to participate in the survey
