AOHC Encore 2023-410 Pregnancy and Occupational Hazards

Video Transcription

Video Summary

In this video, Marina discusses the topic of occupational hazards and pregnancy, focusing on the gap in academic curriculum surrounding this topic in occupational medicine. She highlights the importance of understanding how reproductive hazards can lead to adverse outcomes and discusses the role of the epigenome in the development of negative outcomes. Using arsenic as an example of a reproductive toxicant, Marina explains its effects on the epigenome and mentions other hazards such as endocrine disruptors. She then delves into select hazards with critical windows during pregnancy, including varicella, parvovirus B19, heat, shift work, noise, and ergonomic hazards. Marina also emphasizes the importance of exercise during pregnancy and its positive effects. She discusses the different endpoints during pregnancy, such as reproductive outcomes that affect the mother and developmental outcomes that affect the fetus. She touches on the Barker hypothesis, which suggests that exposure to hazards during pregnancy can affect chronic diseases in offspring later in life. Marina also explains the three time frames or periods of hazardous exposure: before pregnancy, during pregnancy, and after pregnancy. She discusses the effects of environmental hazards on oocytes and the potential risks associated with specific hazards. Throughout the video, Marina highlights the importance of risk communication and the need for further research in this field. <br /><br />No credits were granted in the transcript for this video.
