North American Indigenous adolescent substance use

Area of Science:

• Public Health
• Adolescent Health
• Indigenous Health

Background:

• Substance use among adolescents is a significant public health concern.
• Indigenous youth face unique challenges and disparities in health outcomes.
• Understanding patterns of substance use in specific populations is vital for targeted interventions.

Purpose of the Study:

• To examine the developmental trajectories of problem drinking and monthly marijuana use.
• To investigate these patterns among North American Indigenous adolescents in the upper Midwest and Canada.

Main Methods:

• Utilized panel data from a community-based participatory research project.
• Included responses from 619 Indigenous adolescents residing on or near 7 reservations/reserves.
• Focused on a single Indigenous cultural group to ensure cultural homogeneity.

Main Results:

• Problem drinking and monthly marijuana use rates increased throughout adolescence.
• The most rapid increase in substance use was observed in early adolescence (pre-age 15).
• Females reported higher use before age 15, while males reported higher use in later adolescence.

Conclusions:

• Early adolescent substance use prevention is critically important.
• Gender-responsive programming may be a valuable approach for intervention.
• Findings underscore the need for culturally relevant and timely support for Indigenous youth.
