AI Article Synopsis

  • The study explores the connection between air pollution and psychiatric disorders in pregnant women during the perinatal period, focusing on issues like postpartum depression (PPD).
  • Nine articles were reviewed, finding that exposure to pollutants like particulate matter (PM) and nitrogen dioxide (NO) significantly links to the onset and severity of PPD, particularly in the first year after childbirth.
  • The authors conclude that further research is needed to better understand these connections and develop interventions addressing the mental health impacts of air pollution during and after pregnancy.

Article Abstract

Background: The aim of the present study was to summarise the available data about the link between air pollution exposure and the new-onset and severity of psychiatric disorders in pregnant women during the perinatal period.

Materials And Methods: We selected articles published until June 2022 on PubMed and the Web of Science. Pollutants included were PM (particulate matter 2.5 micrometres and smaller), PM (particulate matter 10 micrometres and smaller), NO (nitrogen dioxide), O (ozone), SO (sulphur dioxide), CO (carbon monoxide), PBDEs (polybrominated diphenyl ethers), PFAS (per- and polyfluoroalkyl substances), lead, and cadmium. The perinatal period was considered as the time of pregnancy until one year after childbirth.

Results: Nine studies were included; most of them evaluated the association between exposure to air pollutants and the onset of Postpartum Depression (PPD). Two studies showed an association between, respectively, only PM and both PM and NO exposure and PPD onset 12 months after childbirth, while another study found a significant association between NO exposure and PPD occurrence 6 months after childbirth. PBDE blood levels were associated with more severe depressive symptoms. Lastly, one study observed a link between stressful symptoms and exposure to PM PM during pregnancy.

Conclusion: More comprehensive and uniform studies are required to make a roadmap for future interventions, given the growing relevance of issues such pollution and mental health, particularly during the perinatal period.

Background: Obese subjects undergoing weight loss often fear the Yoyo dieting effect, which involves regaining or even surpassing their initial weight. To date, our understanding of such long-term obesity and weight cycling effects is still limited and often based on only short-term murine weight gain and loss studies. This study aimed to investigate the long-term impacts of weight cycling on glycemic control and metabolic health, focusing on adipose tissue, liver, and hypothalamus.
