The articles “Sociodemographic and Maternal Predictors of Elevated Blood Lead Levels during Pregnancy in Adjara, Georgia” and “Maternal Blood Lead Level and Its Association with Birthweight and Preterm Birth in Adjara, Georgia” have been published in prestigious scientific journals with co-authorship by Tinatin Manjavidze, Associate Professor at the School of Health Sciences of the University of Georgia. Below, you can read the author’s answers to our questions about the research.
1. Why did you become interested in researching this topic?
Lead exposure has been one of the major public health challenges in Georgia for several years. More broadly, the impact of environmental pollutants on health is currently one of the most important areas of research worldwide. An increasing body of evidence shows that people are continuously exposed to various environmental factors, which can have significant effects not only on their own health but also on the health of future generations.
I was particularly interested in the impact of lead exposure on pregnant women and fetuses, because during pregnancy, any environmental factor can affect a child’s health. It is well established that lead can cross the placenta and affect fetal growth and development. At the same time, lead is a potent neurotoxin, and its adverse effects may become apparent not only at birth but also during a child’s subsequent development.
Interest in this issue in Georgia increased particularly after lead exposure emerged as a significant problem affecting children’s health. Although the situation has improved considerably in recent years, lead exposure remains an important concern. Therefore, it was important to study not only the prevalence of lead exposure among children but also among pregnant women and its potential consequences for newborn health.
Our studies provided a unique opportunity to use data from the Georgian Birth Registry and the lead monitoring programme in the Adjara region to examine both the prevalence of lead exposure among pregnant women and its potential impact on newborn health. As an epidemiologist, I found it particularly important that the findings could have direct practical implications. Such research does not remain solely within the academic sphere; it can help public health professionals and decision-makers develop effective preventive measures and better protect the health of mothers and children.
2. What impact could the findings of this research have on people’s lives?
The findings help decision-makers and the healthcare system better identify groups that are at high risk of lead exposure. Our research showed that, despite significant improvements in recent years, elevated blood lead levels among pregnant women remain a public health concern. We also found that higher blood lead levels are associated with lower birthweight in newborns. This information is important for planning preventive measures and improving maternal and child health.
3. How can students become involved in this area of research, and why would you recommend that they do so?
Students can become involved in ongoing research in public health, epidemiology, environmental health, and biostatistics. This field is particularly interesting because it combines data analysis with work on real-world public health problems. Such research allows students to contribute to addressing issues that directly affect people’s health and quality of life.
We are currently also conducting a study aimed at assessing knowledge and attitudes regarding lead exposure among the general population and healthcare professionals. Student involvement, particularly in the data collection stage, would be very valuable.
4. What were the main challenges and skills involved in conducting this research?
One of the main challenges in conducting this research was linking and validating data from different sources, including the lead monitoring programme and the Georgian Birth Registry. In general, this is a particularly important stage of the research process.
It was also essential to correctly assess and apply modern epidemiological and statistical methods in order to appropriately evaluate the associations between lead exposure and pregnancy outcomes, as well as the determinants that make pregnant women more vulnerable to lead exposure. Throughout this process, data analysis and critical thinking skills were particularly important.
5. What response has this particular research received so far?
The findings have generated considerable interest among both academics and professionals working in public health, as this is one of the first large-scale studies in Georgia to examine the relationship between blood lead levels in pregnant women and health outcomes in newborns. The papers were published in international peer-reviewed journals, further demonstrating the importance of the topic and the reliability of the findings.
6. What additional funding and support did this research receive?
The research was conducted within the framework of Georgian-Norwegian cooperation in public health. I worked on the project as a postdoctoral researcher at UiT The Arctic University of Norway, in close collaboration with university professors and researchers.
The research did not receive any additional financial support. However, successful implementation of the study was facilitated by partnerships between various institutions, including collaboration with the National Center for Disease Control and the Adjara Public Health Center, which enabled access to the necessary data.
The collaboration between Georgian and Norwegian researchers was particularly important, making it possible to apply modern epidemiological methods and share international expertise. The research relied on unique data sources available in Georgia, including the Birth Registry and data from the lead monitoring programme.
It is worth noting that such international collaboration contributes not only to the implementation of individual research projects but also to the professional development of Georgian researchers, knowledge exchange, and the strengthening of evidence-based decision-making in public health in Georgia.
