PALMA, David  and  EQUIPO INVESTIGADOR PROYECTO REPTE et al. Personality traits associated with the substance consumption in young people in a context of vulnerability. Gac Sanit [online]. 2021, vol.35, n.6, pp.542-550.  Epub Apr 04, 2022. ISSN 0213-9111.


To analyze the patterns of alcohol and cannabis consumption, and their associated factors, in young people aged 16 and 21 in a context of vulnerability.


Cross-sectional study based on a pre-test questionnaire from an evaluation study, administered to a convenience sample of 365 young people from Social Guarantee Programs (SGP), or who attended activities of community entities from disadvantaged neighborhoods in Barcelona. Dependent variables were experimental, regular, and problematic alcohol and cannabis consumption, while independent variables were impulsivity, sensation seeking, expectations, and beliefs regarding drug use, social skills, and contextual variables. Associations were established using multivariate logistic regression models.


The prevalence of intensive alcohol consumption (24.2% for binge drinking and 33.3% for binge drinking) and experimental (51.1%) and problematic cannabis use (12.9%) was higher in SGP students than entity youth. Likewise, they presented higher scores on the impulsivity scales, sensation seeking, expectations and beliefs favorable to alcohol consumption. In general, the prevalence of experimental alcohol consumption was higher in girls than in boys. Regular binge drinking was associated with intense sensations seeking (adjusted odds ratio [aOR]: 1.06; 95% confidence interval [95%CI]: 1.01-1.12), while attending SGP was associated with problematic cannabis use (aOR: 2.73; 95%CI: 1.26-5.89). Positive expectations to alcohol and cannabis use were associated with problematic substance use.


Individual risk, linked to the higher risk trajectories of SGP students, is associated with a higher problematic consumption of alcohol and cannabis than in young people from community entities exposed to an environmental risk of high frequency of consumption.
