This paper discusses research designed to investigate community, clinic. and longitudinal patterns in use of lead as a treatment for empacho, a folk illness manifest by gastrointestinal symptoms.
The same questionnaire used in a clinic-based study seven years previously in Guadalajara, Mexico. was used to interview a randomly selected community sample ; in addition. the study was repeated at the same clinic sites that had been studied previously.
The goals were to investigate : (1) What are community wide prevalences of empacho and use of lead based remedies ? (2) To what extent are current patterns of use of lead for treatment of empacho in clinic-based samples similar to those seven years ago.
The attributable risk to the population as a whole from use of lead based remedies was found to be 11% of the households of Guadalajara.
Essentially this same estimate was seen for the 1987 and 1994 clinic populations.
Interestingly, while percentages of lead users have declined since 1987, twice as great a percentage o informants reported treatin empacho.
Other patterns originally identified in 1987 persisted in 1994 ; lead use continues to be associated with lower levels of parental education and income.
