Neonatal outcome: is adolescent pregnancy a risk factor?

Area of Science:

• Maternal and Child Health
• Neonatal Outcomes
• Reproductive Health

Background:

• Adolescent mothers are often associated with poorer pregnancy outcomes, including low birth weight and premature infants.
• This association may be influenced by confounding health and social factors specific to adolescent mothers.
• Previous studies suggest a need to differentiate the impact of adolescent status from other contributing factors.

Purpose of the Study:

• To determine if adolescent mothers deliver infants with poorer outcomes compared to nonadolescent mothers, independent of social and health differences.
• To investigate the independent predictive value of adolescent status and younger adolescent status on adverse neonatal outcomes.
• To identify key health and social factors influencing fetal outcomes in primiparous mothers.

Main Methods:

• A comparative study of infants born to primiparous adolescents (13-18 years) and primiparous nonadolescents.
• Analysis of birth outcomes including size at birth, length of gestation, Apgar scores, and birth trauma.
• Application of multiple and logistic regression analyses to control for health and social variables.

Main Results:

• Adolescent mothers' infants had a statistically significant lower mean birth weight (94 g less) compared to nonadolescent mothers' infants.
• Health and social factors, not adolescent status, were independently associated with adverse infant outcomes.
• Younger adolescent status (≤16 years) did not independently predict low birth weight or other adverse neonatal outcomes.

Conclusions:

• Health and social factors play a more significant role in adverse fetal outcomes for primiparous mothers than adolescent status alone.
• Clinical interventions targeting specific health factors may improve fetal outcomes.
• The findings suggest a need to address underlying health and socioeconomic disparities rather than solely focusing on maternal age.
