Personality and adolescent pregnancy outcomes

Area of Science:

• Psychology and Public Health
• Adolescent Health Research

Background:

• Personality traits are significant predictors of various health outcomes.
• Adolescent pregnancies are associated with poorer birth outcomes compared to adult pregnancies.

Purpose of the Study:

• To investigate the association between personality traits and adolescent pregnancy and birth outcomes.
• To identify personality profiles that may increase risk for adverse pregnancy and birth outcomes in adolescents.

Main Methods:

• Cross-sectional study utilizing data from the National Longitudinal Study of Adolescent Health.
• Analysis of personality traits (five-factor model) in 6529 adolescent girls, with 820 reporting teenage birth outcomes.
• Logistic and linear regression models were employed to assess relationships between personality, teen pregnancy, birth weight, and gestational age, controlling for confounders and stratifying by race.

Main Results:

• Agreeableness and intellect/imagination were linked to a lower likelihood of adolescent pregnancy.
• Neuroticism, conscientiousness, and extraversion were associated with an increased likelihood of adolescent pregnancy.
• Higher neuroticism correlated with lower birth weight and gestational age in Black girls; conscientiousness was linked to lower gestational age in non-Black girls. Late or no prenatal care was associated with higher intellect/imagination.

Conclusions:

• Personality factors are under-researched in relation to adolescent pregnancy and birth outcomes.
• Understanding these personality-outcome links can inform targeted public health interventions for at-risk adolescent populations.
• Interventions could be tailored to address specific personality traits, such as high neuroticism, to improve pregnancy and birth outcomes.
