Objectives: Periodontal inflammation during pregnancy has been associated with complications around childbirth (e.g., pre-eclampsia, preterm birth), yet additional research is needed to explore the relation between periodontal inflammation and postpartum outcomes. Psychological stress and gingival inflammation have also previously been associated, yet little work has explored the relation between gingival health and perinatal stress. This study was aimed to investigate gingival health trajectories and perceived stress during pregnancy and postpartum.

Methods: Participant data from the Center for Oral Health Research in Appalachia (COHRA2) cohort study (n = 1,020) included a gingival health evaluation via the Oral Rating Index (ORI) at four time points (pregnancy, 10 weeks, 12 and 24 months postpartum). Latent class growth modeling (LCGM) was used to extract ORI trajectory classes. ANOVA was then used to determine possible ORI group differences in perceived stress levels at six time points (pregnancy, 10 weeks, 6, 12, 18, and 24 months postpartum).

Results: Three ORI trajectory classes were identified (low-rating, average rating, and high-rating). The low-rating class (31.0%) had a quadratic trajectory (u-shape, ß = 0.111, p < .001) and the high-rating class (19.9%), an inverse u-shape trajectory (ß = -0.211, p < .001). The average class (49.1%) was stable across time (ß = 0.002, p = .860). ANOVA results indicated the low-rating class to differ significantly in perceived levels of stress from the high-rating class (p < .05) at all time points except 24 months postpartum (p = .165).

Conclusions: Three unique classes of ORI scores throughout the perinatal period were identified. Given the consistent relation between ORI and stress, results suggested that women with lowest ORI scores may also have the most extreme levels of perceived stress. Future studies could assess whether interventions targeted to reduce postpartum stress also result in improved gingival health after childbirth in at-risk groups.
