Obese adolescent women are less likely to use contraception, and are also less likely to use it consistently when compared with normal weight peers, according to a study of 900 adolescent women aged 18 to 19. The mean proportion of weeks in which adolescents reported sexual intercourse was 52% with no difference by weight status. Researchers found:
• Obese adolescents had a lower proportion of weeks where any contraception was used compared with normal weight adolescents (84% vs 91%) among weeks in which adolescents reported sexual activity.
• Obese adolescents had a lower proportion of weeks with consistent contraceptive use (68% vs 78%) and oral contraceptive pill use (27% vs 45%) compared with normal weight adolescents.
• All other relationships by weight status were not statistically significant.
