Does early adolescent sex cause depressive symptoms?

Area of Science:

• Psychology
• Sociology
• Public Health

Background:

• A prior study suggested a link between early sexual intercourse and depressive symptoms.
• This finding was used to support abstinence-only sex education programs.
• The causal relationship between early sexual activity and depression requires further investigation.

Purpose of the Study:

• To examine the relationship between early teen sexual activity and depression.
• To determine if the association between early sex and depression is causal.
• To evaluate the potential mental health benefits of abstinence-only sex education.

Main Methods:

• Utilized data from the National Longitudinal Study of Adolescent Health (Add Health).
• Employed cross-sectional and difference-in-difference estimation techniques.
• Controlled for individual and family-level observable characteristics.

Main Results:

• Cross-sectional analyses showed a positive association between early sexual activity in females and adverse mental health outcomes (depression, suicidal ideation).
• Difference-in-difference estimates revealed no significant relationship between early teen sex and depressive symptoms.
• The observed association in cross-sectional data may be attributed to unmeasured confounding factors.

Conclusions:

• The positive association between early sexual activity and depression is likely due to unmeasured heterogeneity, not a causal link.
• Abstinence-only sex education may not yield mental health benefits by preventing early sexual activity.
• Policy implications suggest focusing on factors beyond sexual activity for adolescent mental well-being.
