Physical and psychosocial factors associated with psychostimulant use in a nationally representative sample of French adolescents Specificities of cocaine, amphetamine, and ecstasy use.
Patterns of psychostimulant (PST) use, psychological and physical factors, and family relationships were investigated in a nationally representative sample of adolescents. The differences between users of cocaine (Cc), ecstasyMDMA, and amphetamine (EA) were analyzed, taking into account gender differences. Substance use, psychological factors (lifetime suicide attempts, suicidal thoughts in the previous year, visits to a mental health professional), physical factors (health and body shape perceptions (BSP), body mass index (BMI)), and family relationships (existence of disagreements with parents, relationships with mother and father) were investigated in 26,351 17-year-old French adolescents. Lifetime suicidal behavior was strongly associated with EA use only. Suicidal ideation in the previous year was associated with Cc use among both boys and girls and associated with EA use among girls. Compared to Cc users, more EA users were overweight, while more Cc users were underweight compared to EA users. BSP, BMI, and EA use were related in girls only. Having a good or very good relationship with both mother and father was negatively associated with Cc use in boys and girls. Girls who had a good or very good relationship with their fathers seemed to be less prone to use EA. Boys with a good or very good relationship with their mothers seemed to be less prone to use EA. The results of the present study could serve as a basis for prevention and harm reduction strategiesprograms targeting youth use and for the adaptation of these strategiesprograms according to substance and gender.
