Abstract
Migration from Mexico to the U.S. is the largest sustained flow
of immigrants
anywhere in the world with 11% of Mexican-born people living as
migrants in the U.S. International
migrants have been identified as a vulnerable population for HIV
and the migration process has been
cited as a factor for HIV infection. Higher rates of HIV in Mexico
have been linked to Mexican returning-
migrants from the U.S. Although condom use among migrants has been
identified at higher levels of use
when compared with non-migrants, the determinants for greater
condom use among migrants are not
well defined. Social networks and peer effects have been shown to
significantly improve health-related
behaviors. The aim of this study was to understand the association
between peer influences
and condom use among Mexican migrants to the US, migrants who had
returned to Mexico from the US
and men who had never migrated. The data for this study were
obtained from a mixed
methods data collection study looking at different aspects of
Mexican-migrant and non-migrant health
and sexual risk behaviors. Bivariate logistic regression analysis
was conducted to identify factors of
interest associated with condom use. Multivariate logistic
regression analysis was used to create two
models that included peer effects as predictors of condom use.The
study sample included 224
male Mexican migrants, 318 returning migrants and 336 non-migrants.
Age, migrant status, marital
status, duration of peer's friendship, peer's condom use and peer's
advise about condom use were
potential independent predictors of condom use during last sex.
This study did not show a significant
difference between migrant group and condom use as previously shown
by other studies. Multivariate
logistic modeling showed that peer's condom use (OR= 7.52, 95% CI=
3.00, 18.87), and peer's advise
about condom use (OR= 3.57, CI= 1.46, 8.72) were significant
predictors of condom use during last sex.
This study suggests that peer influences may impact condom use and
that this may partially
explain the differences previously reported in condom use between
Mexican migrant and non-migrant
populations. Understanding the role of social networks among
migrant and Mexican non-migrant
populations may allow the design of novel effective and
comprehensive HIV/AIDS prevention
interventions.
