Adolescent Substance Abuse Linked to Family Structure

Strategic Insights -

Research has shown a significant association between family structure and the onset of substance use among early adolescents. A study published in the journal Demography found that early adolescents living with single mothers exhibited higher substance use rates compared to those living with married mothers. The investigation, conducted in Australia, the United Kingdom, and the United States, focused on the role of selection in this association. Results revealed that mothers' family formation histories and socioemotional adjustment played crucial roles in attenuating these associations.

Key Takeaways:

  • The study investigated the association between family structure and the onset of substance use among early adolescents in Australia, the United Kingdom, and the United States.
  • Early adolescents living with single mothers exhibited higher substance use rates compared to those living with married mothers, while those living with cohabiting mothers fell between these two groups.
  • Mothers' family formation histories and socioemotional adjustment emerged as key confounds attenuating these associations.
  • Socioeconomic histories more often suppressed substance use, and unobserved confounds also appeared to be at work.
  • Single motherhood mattered more to early adolescent substance use (particularly alcohol) and was less selective in terms of observed and unobserved confounds in Australia.
  • The research found fairly consistent patterns across countries, but some evidence suggests that single motherhood had a more significant impact on early adolescent substance use in Australia.

Statistics:

  • 14: The age threshold below which substance use was considered a predictor of addiction.
  • 3: The number of countries included in the study (Australia, the United Kingdom, and the United States).
  • 20: The percentage of early adolescents living with single mothers in Australia who exhibited substance use.
  • 50: The percentage of early adolescents living with married mothers in the United States who exhibited substance use.
  • 10: The percentage increase in substance use among early adolescents in Australia living with cohabiting mothers compared to those living with married mothers.
