To identify, risk factors for drug use among young males in southwest
China a cross-sectional survey and a non-concurrent cohort study were
conducted. Demographic, behavioral and drug-use information was collec
ted from young males aged 18-29 years. The non-concurrent cohort inclu
ded the period 1 January 1991 to 1 August 1994. A total of 1548 subjec
ts were interviewed The cumulative incidence increased between 1991 an
d 1993. Multivariate analysis identified the following significant ris
k factors for drug use: being divorced/widowed/separated, having been
encouraged by friends/others to try drugs, smoking cigarettes, belongi
ng to the Fingpo ethnic group, and having a family member who used dru
gs in 1991. More than 6 years of education was a protective factor for
drug use. Drug use in the community was associated with having been e
ncouraged by friends or others to try drugs (71%), to smoking cigarett
es (50%), and to belonging to the Fingpo group (24%). The results are
consistent with community based prevention approaches which should be
studied carefully because of the unique cultural and epidemiological s
ituation in China.
