[Prevalence and risk factors related to sale of cigarettes to minors in stores in Mexico City]

Abstract

Objective: To identify the prevalence of the sale of cigarette to minors in stores in Mexico City.

Material and methods: A cross-sectional study was done applying a questionnaire to salespersons in stores that sell cigarettes. The SCINCE 2000 from INEGI was used to select and sample two Basic Geostatistical Areas (AGEB) per Delegation and a census of stores was carried out.

Results: A total of 577 stores were visited, 73% sold cigarettes to minors, 58% sell loose cigarettes, only 2.6% asked the buyer's age, and 1.2% requested identification. Among the salespersons, 51% were men, 37% had secondary school studies, 57% were smokers, 42% had children underage, and 99% knew that the sale of cigarettes to minors is prohibited. The multivariate analysis established an explicative model and it was discovered that when the salesperson was male or if the cigarettes were sold individually the probability of sale was 2 and 5 times higher respectively.

Conclusions: The sale of cigarettes to minors in Mexico City is not associated with the personal characteristics of the salespersons or with the stores.
