Drug use and associated factors among rural adolescents in Costa Rica

Factors associated with tobacco, alcohol, and other drug use among youth living in West Central Mexico

AIM

To determine the prevalence of drug and substance abuse among high school students in Jalisco and its association with the severity of health, behavior and psychosocial problems in order to provide evidence for possible prevention and treatment needs.

METHODS

A multi-stage random sample of Jalisco high school students was given a paper-and-pencil survey based upon an adapted version of the drug use screening inventory (DUSI) (n = 24699; n = 2832). The DUSI showed adequate psychometric characteristics in this population. The statistical analyses accommodated the complex survey design with attention to unequal probability of selection and clustering of participants within schools and regions.

RESULTS

An estimated 44% of the students had smoked tobacco, one in five students was a current smoker, and one in four students used to smoke but had not smoked for one year or more. By contrast, 6.8% of the students reported having used marijuana, cocaine, or both. Behavioral problems, deviant peer affiliation, and troubled families were independently associated with drug use. One in two students who used tobacco or alcohol had used these drugs in the past year (46% and 54%, respectively), and one in four students who used marijuana or cocaine in their lifetime had used those drugs in the past year (28% in both cases).

CONCLUSION

The rates of cocaine use as well as the proportion of current users were higher than expected among high school students and indicate changing patterns of drug use in Mexico. These results corroborate that the general trend of drug use by youth in Mexico is increasing. Results from this study help us better understand the needs of at-risk youth and the need for new treatment and prevention strategies.

Supportive social relationships and adolescent health risk behavior among secondary school students in El Salvador

An increasing number of studies suggest that supportive social relationships in the family and school may exert a protective effect against a number of youth health risk behaviors. This study examines the association between perceived parental social support and perceived social cohesion at school with selected youth risk behavior outcomes (physical fighting, victimization, suicidal ideation, substance use, and sexual intercourse) among 930 female and male public secondary school students studying in the central region of El Salvador. The study questionnaire comprised closed-ended items of parent/school relationships and risk behaviors based on the United States Center for Disease Control and Prevention's Youth Risk Behavior Survey. In regression analyses, female students who perceived low parental social support were significantly more likely to report engaging in all risk behaviors examined, and female students with perceptions of low school social cohesion were more likely to report suicidal ideation, binge drinking, and drug use. Perceptions of parental social support and school social cohesion held fewer but still significant associations across risk behaviors for male students. Male students who reported low parental social support were significantly more likely to report suicidal ideation, drug use and physical fighting, while male students with low perceived school social cohesion were more likely to report physical fighting but less likely to report binge drinking. This study lends support to the importance of supportive social relationships for understanding youth risk behavior and suggests that supportive families and schools may operate differently for female and male students living in El Salvador.
