Washington DC: Women, it is time to take a pause for a cause as a new study suggests that females, who work or lift things a lot, may struggle to get pregnant.
Lead author Audrey Gaskins of the Harvard T.H. Chan School of Public Health said that their results showed that heavy work, both in terms of physical strain and long hours, appeared to have a detrimental impact on female nurses' ability to get pregnant, the Fox News reported.
In the study, Gaskins and other researchers reviewed data on women, who were least 33 years old and at some point had said that they were trying to conceive.
About 44 percent were overweight or obese and 22 percent were current or former smokers.
Sixteen percent of them had rotating shifts at different times, whereas majority of them worked exclusively days or nights.
About one third of the women were on their feet for at least eight hours a day, and 40 percent reported lifting heavy loads up to five times a daily.
According to the researchers, heavy lifting was linked to a 33 percent longer timeline to conception and overweight and obese women had a prominent impact of heavy lifting.
The researchers explained that it was possible that certain working conditions might make pregnancy more likely, and it was also possible that women who struggle to get pregnant may choose to work longer hours.
