Adolescent girls exposed to fine particles would be more prone to irregular menstrual cycles. Such are the results of a new study conducted by researchers from the University medical center in Boston (United States), published in the journal Human Reproduction. To reach these conclusions, researchers drew on a cohort of 34.832 high school students aged 14 to 18 years of age, participating in the program of the national Nurse Health Study 2 (NHS). They have then crossed this information with the parameters of exposure to air pollution derived from the system of monitoring of the air quality (EPA) in the united states.
Endocrine disruption, reproductive
By analyzing these data, the authors of the study found that exposure to air pollution of the young women in the age of going to school was correlated with the irregularity of the menstrual cycle. “Although the exposures to air pollution have been associated with cardiovascular and lung diseases, infertility, and polycystic ovarian syndrome, this study suggests for the first time that pollution disrupts endocrine system reproductive “, says Shruthi Mahalingaiah, assistant professor at Boston University and senior author of the study.
The high levels of particulate matter in air pollution have demonstrated a link with hormonal activity. However, according to the researchers, it was not clear until now if the air pollution was associated with an irregularity of the menstrual cycle. It is the first study that indicated a direct correlation between air pollution and menstrual cycle.
According to the study, the increase in exposure to fine particulate matter disrupts the installation of a menstrual cycle regular teenagers until the beginning of adulthood. Young women most affected live in the west and the north-west of the United States, say the scientists. “These findings support the idea according to which the reduction of fine particle emissions is a priority at the global level and the individual,” concludes the Pr Mahalingaiah.
