A recent study reveals that exposure to air pollution before design could have consequences for children’s health. The researchers observed a link between this exposure and a higher body mass index (BMI) in young children.
This research, conducted by an international team, highlights an often overlooked period: the three month Preceding the pregnancy. The results suggest that fine particles and dioxide ofnitrogen in theair could influence the early development of children, opening up new perspectives on environmental factors and health.
A critical period: before conception
The preconception period, often overlooked, plays A key role in the future health of the child. Sperm and eggs, in phase maturation finish, are sensitive to environmental factors. Increased exposure to pollution During this period could alter their development, with repercussions on the growth of the child.
The study analyzed the data of 5,834 mother-child couples in Shanghai. Researchers used models ofautomatic learning To estimate daily exposure to pollutants, including fine particles (PM2.5 and PM10) and nitrogen dioxide (NO2). These estimates were crossed with the measures of weight And children’s size up to the age of two.
Measurable effects and concrete solutions for future parents
Children exposed to high levels of PM2.5 before the design presented an increase of 0.078 of their standardized BMI to two years. For PM10s, the increase was 0.093 kg/m². These differences, although modest, could have a significant impact on the population level, given the prevalence of air pollution.
-Researchers highlight the importance of reducing exposure to air pollution for future parents. Wearing a mask, using air purifiers or limiting outputs during pollution peaks are simple but effective measures. These precautions could help prevent the risks of infantile obesity.
Research to continue
Although this study is observational, it opens the way to new investigations. Researchers plan to study the impact of pollution in other regions, such as the sud California, where pollution levels vary considerably. This research could confirm whether the effects observed in Shanghai can be generalized to other environmental contexts.
In addition, scientists plan to assess the effectiveness of air purifiers to reduce the health risks linked to pollution. Interventional studies could determine whether these devices, used before and during pregnancy, limit the harmful effects on the growth and health of children. These works could lead to practical recommendations for future parents.
