The timing of norplant insertion and postpartum depression in teenagers

This study tested the hypothesis that teenagers who have Norplant inserted during the puerperium report more depressive symptoms during the first postpartum year than their peers who do not receive Norplant.

We studied the prevalence of depressive symptoms in a group of 212 mothers aged 19 years less, in relation to the timing of Norplant insertion. The participants were divided into 3 groups: 100 (47%) had Norplant inserted during the puerperium (early Norplant users); 72 (34%) had Norplant inserted during the next 10 months (late Norplant users); and 40 (19%) used other contraceptives (40% oral contraceptives; 17% condoms; 43% nothing). Depressive symptoms were measured with the Center for Epidemiologic Studies - Depression Scale. Postpartum depression was defined as a scale score >/=16, 6-12 months after Norplant insertion or delivery. Variables examined as potential confounders were identified a priori from a review of the literature and controlled for in analysis of variance.

At delivery, members of the 3 contraceptive groups did not differ significantly with regard to age, race, parity, educational, marital, or socioeconomic status. Late Norplant users were, however, more apt to have new boyfriends (p =. 03), to rate the support they received from the baby's father as poor (p =.004), and experience depression prior to Norplant insertion (p =.02). Contrary to the study hypothesis, late rather than early Norplant insertion was associated with postpartum depression. Multivariate analyses identified 3 independent predictors of the severity of depressive symptoms at follow-up (depression prior to Norplant insertion, a new boyfriend at delivery, and late Norplant insertion); R(2) = 41.3%.

Contrary to the study hypothesis, puerperal Norplant insertion did not exacerbate postpartum depression. Delaying Norplant insertion may increase the risk of depression during the first postpartum year, particularly in teenagers with other psychosocial risk factors.
