Prenatal exposure to nicotine and postpartum depression: a systematic review and meta-analysis
Abstract
Purpose: Postpartum Depression (PPD) is the most common mental health complication of childbirth, and has short-term and long-term consequences for mother, child, and the entire family. PPD is a function of several factors. Prenatal exposure to nicotine (PEN) by Active Tobacco Smoking (ATS), Secondhand Smoking (SHS), or Electronic Nicotine Products (ENPs) is a major potential risk factor. This systematic review and meta-analysis aim to summarize and evaluate all evidence regarding the association between PEN and PPD.
Methods: We searched the following databases, PubMed, Medline, Cochrane, EMBASE, and CINHAL, for studies published between Jan.1st ,2000&Sep.19th ,2024, with the outcome PPD. Studies quality was assessed using the Newcastle-Ottawa Scale. Pooled Prevalence (PP) was calculated using the Freeman-Tukey Double Arcsine Transformation method. Pooled Odds Ratio (pooled-OR) was estimated using a random-effects model. Sensitivity analysis was conducted using the leave-one-out technique.
Results: Of 29 studies in the systematic review, 26 included in the meta-analysis. PP of PPD was 0.15,(95% CI[0.12-0.17]; I2 = 99.80%,p < 0.001). Pooled-OR for ATS 1.96,(95%CI[1.59-2.41]; Z = 6.46,p < 0.001), 1.22,(95%CI[0.69-2.18], Z = 0.69,p = 0.49) for SHS, and 1.14,(95%CI[0.82-1.58,Z = 0.78,p = 0.43) for ENPs. While the overall Pooled-OR for all PEN was 1.74,(95%CI[1.44-2.12]; Z = 5.59,p < 0.001), funnel plots and Egger test showed no evidence of publication bias. Sensitivity analysis…
How strong is the evidence?
Evidence Hub reads this as a meta-analysis, done in people. Its evidence level is 1 of 5 (Highest · pooled evidence). Pooled evidence from several studies sits at the top of the evidence pyramid.
