According to foreign media reports, a new Danish study indicates that women over 35 who consume alcohol during pregnancy, frequently work night shifts, lift more than 20 kilograms daily, or are either overweight or underweight face an increased risk of miscarriage.
The University of Copenhagen analyzed data from over 90,000 local pregnant women, revealing that more than 25% of first-time miscarriages could have been prevented.
Senior researcher Anne-Marie Nybo Andersen from the University of Copenhagen emphasized that both younger and older women, along with policymakers, should recognize that pregnancy after age 35 substantially increases miscarriage risk.
She stated the study's key message is that miscarriages are preventable, stemming from lifestyle factors rather than specific medications.
The study was published in the International Journal of Obstetrics and Gynaecology.
Andersen emphasized that this research adopts a population health perspective. While it serves as a reference for couples, policymakers responsible for maternity leave policies and workplace regulations should also take note.
British obstetricians and gynecologists described the report's findings as "interesting," noting that 20 kilograms roughly equals the weight of luggage for a vacation, a load most people only occasionally carry.
Experts also recommend that women planning pregnancy maintain a balanced diet, avoid being underweight or overweight, quit smoking themselves, and encourage their partners to do the same.
