Abstract
To evaluate in adolescents the association between body mass index (BMI) and obstetric outcomes and to determine whether the outcomes in the BMI groups of adolescents differ from those of a low-risk population of adult women.
This is a nationwide population-based register study. Obstetric outcomes of 31,386 singleton primiparous adolescents were evaluated in relation to BMI classes. Furthermore, the outcomes of the adolescents and 178,844 normal weight, nonsmoking, singleton primiparous women, 25-29 years old with no known comorbidity, defined as standard women, were compared. Multiple logistic regression models were used. Results are presented as crude odds ratios (ORs) or adjusted ORs and with a 95% confidence interval.
Compared with normal weight adolescents, obese adolescents had a lower chance of a normal vaginal delivery (VD)-76% versus 85% [adjusted OR 0.61 (0.55-0.68)], a higher risk for acute cesarean section (CS)-8.9% versus 4.5% [adjusted OR 2.45 (2.08-2.88)], and stillbirth-0.7% versus 0.2% [adjusted OR 3.17 (1.74-5.77)]. Compared with standard women, overweight adolescents had a higher chance of a normal VD-82% versus 75% [crude OR 1.53 (1.44-1.64)] and a lower risk for acute CS-6.3% versus 7.1% [crude OR 0.85 (0.76-0.95)]. Obese adolescents had a lower risk for instrumental VD-8% versus 13% [crude OR 0.61 (0.53-0.71)] and obstetric anal sphincter injury-1% versus 3% [crude OR 0.38 (0.26-0.57)].
Several adverse obstetric outcomes were obesity related among adolescents. Overweight adolescents seemed to have better obstetric outcomes than standard women, something to consider when optimizing resources for women during pregnancy and delivery.
