The unexpected effects of climate change are being born in Chile – Nation World News

Chile and the whole planet has seen has been seriously affected by the results of Climate change. Increases in temperature, decrease in rainfall, drought, pollution, melting of glaciers, migration and extinction of species are some of these.

But the consequences of the event are not only climate. It also has other unexpected consequences, especially on health.

Now, new research has found that climate change increased risk of preterm birth, That is, birth before 37 weeks.

The study, titled “Climate Change and Premature Birth: A Narrative Review,” led by Sebastian Illanes, a gynecologist and academic at the Universidad de los Andes School of Medicine, maintains that Climate change is responsible for increase in premature births,

“Pregnancy imposes a very significant challenge on the mother and this increases during pregnancy. Furthermore, maintenance of pregnancy requires a carefully controlled balance between the maternal and fetal compartments, a balance that can be upset by a variety of stressors, including climate change”, explains Illness.

Research establishes that fossil fuel use acts by generating greenhouse gases (for example, CO2 and methane), raising the average atmospheric temperature and causing harmful air pollution, Lowering the pH of the ocean surface and increasing its temperature. Changes in both the atmosphere and the ocean increase the likelihood of extreme weather events, which alter human habitats which, in turn, health effects of pregnancy

according to research, Climate change increases maternal physiological stress (directly through climate impacts and indirectly through housing and social distancing) and increased disease risk. Each of these factors act to increase the risk of preterm birth.

How did you come to this conclusion? The answer is complex, Illanes speculates. “The graph (below) shows that there has been an increase in preterm births in recent years … but mainly at the expense of late preterm births, which occur between 32-37 weeks, before early ones. No changes occur at 32 weeks”.

“It can be interpreted that these types of deliveries are linked to more biological causes, do not change, and are influenced by external factors. affects pollution or other vulnerability factors… If a patient in Puente Alto lives next door to a town where shootings are occurring, what is the triggering external factor, pollution, vulnerability or stress? That’s why there is no global figure, because These are particular to each location and situation, and the phenomenon is multifaceted.”, explains the academic.

climate change (broadly, increase in ambient temperature, with consequential changes in exposure to extreme weather events, human behaviour, nutrient availability and movement), “Has the ability to increase the magnitude of the physical challenge for the mother to disrupt the carefully regulated balance between mother and fetus”, says the academic.

One of the direct climate change factors representing the greatest risk is extreme heat rise,And as the article mentions, there is a link between heat waves and preterm birth. “However, the effects can be subtle. For example, changes to heat stress affect normal human behavior (i.e., restrict exercise during the day) and alter the availability and quality of food, which in turn May be associated with increased risk in pregnancy.

gynaecologist believes that “what needs to be understood is that, because of the interrelated nature of climate change impacts, Avoiding these risks through targeted interventions will become increasingly difficult for most countries. Perhaps the most important conclusion to be drawn is that if we are serious about protecting health during pregnancy, we must act now to address the root causes of climate change, as stopgap interventions alone are unlikely to be sufficient. Is.

except, “Many of these interventions are expensive And they will not help the very significant percentage of mothers and babies in countries that do not have the resources to adopt such methods”, Illanes concluded.
