Una aproximación socioepidemiológica a la tuberculosis pulmonar entre migrantes en México.

Estudio de caso del Valle de Culiacán en el estado de Sinaloa

Abstract

This case study is a socio-epidemiological investigation of socio-economic and epidemiological conditions of migrant field workers (jornaleros) from the Culiacan Valley in the state of Sinaloa, northwest Mexico, 1997. It aims to analyse the influence and determination of socio-economic factors over the jornaleros' susceptibility to tuberculosis. A survey consisting of 942 questions was carried out among jornaleros' families. ?'he sample was made up of 5 301 subjects, divided in 74 field settlements with varying degrees of basic living infrastructure. At the time of the research, this sample represented 6.6% of a population of 75 000 peasants, living in 240 field settlements in the area. The results show a much higher prevalence of respiratory symptomatic suspects of lung tuberculosis than the national average. They also show how social and economic factors may be responsible for this phenomenon. This study helped in the identification and organization of some of the risk processes which contribute to the definition of respiratory symptomatic population suspect of lung tuberculosis
