Background/Objectives: Postpartum depression seriously affects the safety and health of mothers and children. Online cognitive behavioral therapy is considered to be a promising treatment; however, whether it is effective at improving postpartum depression is inconsistent and the specific intervention measures are not the same. The objectives of this study were to comprehensively review the effects of online cognitive behavioral therapy on postpartum depression and further explore the specific intervention measures. Methods: A literature search was conducted using thirteen electronic databases and two clinical trial registries from the establishment of the databases to 31 December 2023. The study selection and data extraction were independently performed by two researchers. The latest Cochrane Risk of Bias tool was selected to evaluate the quality of the included studies. Data were analyzed using Review Manager 5.4, and the certainty of the evidence was evaluated using the online GRADEpro tool. Eighteen studies involving 3689 women were included. Results: The results showed that online cognitive behavioral therapy was effective at improving postpartum depression. A subgroup analysis showed that the duration of online cognitive behavioral therapy with total intervention was 9 weeks and above, the total intervention number was 12 times or fewer, and using a website or Zoom online conference room as the intervention platform could more significantly improve postpartum depression. In particular, providing professional guidance could be more effective. Conclusions: In summary, online cognitive behavioral therapy was effective for postpartum depression. Furthermore, this study found out how specific intervention measures of online cognitive behavioral therapy could be more effective. Finally, nurses can participate in the therapy to improve access to evidence-based treatment.

Background/Objectives: Pregnancy and childbirth are independent risk factors for pelvic floor injury. The choice of delivery position, as an interventionable factor during labor, has received much attention. This study aimed to assess the impact of sitting delivery on pelvic floor function by observing the outcomes of the perineum, duration of the second stage of labor, integrity of pelvic floor structure, and postpartum pelvic floor function. The goal was to provide scientific evidence for optimizing delivery management and reducing the risk of pelvic floor injury. Methods: This was a non-randomized study (based on patient choice). A total of 222 primiparous women who delivered at our hospital from February to August 2023 were selected and divided into the control group (n = 88) and the sitting group (n = 134). The second stage of labor in the control group was delivered in the traditional bladder lithotomy position, while the sitting group delivered in a sitting position. The duration of the second stage of labor, delivery method, degree of perineal laceration, postpartum 2 h bleeding volume, and the occurrence of urinary incontinence and sexual dysfunction 1 year after delivery were observed in both groups. Results: The rate of perineal lateral incision in the sitting group was lower than that in the control group (24.6% vs. 48.9%, aOR = 0.37, p < 0.001); the adjusted mean difference in second-stage duration was −11.65 min (95% CI: −25.35 to 2.05, p = 0.095), indicating no statistically significant difference after adjustment. In unadjusted subgroup analysis, a larger point estimate for reduction was observed in women aged < 30 years (median difference −16.0 min, p = 0.033), but the interaction test was not significant. For urinary incontinence and sexual dysfunction, there were no statistically significant differences between the two groups. Conclusions: Sitting delivery was associated with a lower episiotomy rate and, in unadjusted analysis, a shorter second stage (although the adjusted difference was not significant), and it did not increase the incidence of urinary incontinence or sexual dysfunction at one year postpartum.
