Summary: | Background: Many teenagers experiment with addictive
substances such as alcohol. The objective of this study was to estimate
the frequency of binge drinking among secondary school
students and its relationship with sex, grade, and type of school, as
well as with urban contextual factors of the school neighborhood:
socioeconomic level, density of alcohol outlet premises, and tourist
pressure.
Methods: This was an observational cross-sectional study.
The study population were the students of 8th and 10th grade (2nd
and 4th year of ESO) in the city of Barcelona in 2016. Alcohol
use, sex, grade, type of school and school neighborhood were
taken from the FRESC survey. The wealth of the neighborhood
and tourist pressure were extracted from municipal statistics. The
density of alcohol outlets was obtained by direct observation with
the OHCITIES instrument. We estimated the prevalence of binge
drinking (consumption of five or more units on one occasion) stratifying
by age, sex and ownership of the school. We calculated a
robust Poisson regression model with the individual and contextual
variables and analyzed the situation of those neighborhoods
with the highest prevalence of binge.
Results: The self-declared frequency of binge drinking in the
last 30 days was 6.1% in this sample of 2,329 students, 2.2% in
8th grade and 10.3% in 10th grade. It was higher in boys (7%) than
in girls (5.1%), and slightly higher in private subsidized schools
(6.4%) than in public schools (5.5%). In the Poisson regression
models, neither the coefficients of the three contextual variables
nor the type of school reached statistical significance, contrary to
those obtained with the individual variables of sex and year. The
adjusted prevalence of binge in the 36 neighborhoods ranged from
0 to 18.2%. Comparing the contextual variables of the 8 neighborhoods
with the lowest prevalence of binge with the others, both a
greater density of local alcohol sales and higher tourism pressure
were associated with a higher prevalence of binge drinking, while
for wealth there were no significant differences.
Conclusions: The use of alcohol in early adolescence is related
to individual variables such as sex and age. Urban contextual
factors such as a higher tourist pressure and the density of premises
that sell alcohol may exert also some influence.
