Researchers in Sweden have canceled a major study of women with pregnancies that lasted more than 40 weeks – which would generally be considered full – after six babies died, local media reported last month.

The study, which began in 2016, was stopped in October 2018 after five babies were stillborn and one baby died in the first few days of life.

The team wanted to compare the outcomes of the health of babies & mothers and mothers in women after 41 weeks with those of women after 42 weeks and see if factors such as variations in women's personalities and demography played a role.

It is standard in many Swedish hospitals not to induce up to 42 weeks, but these babies are there an increased risk of a low oxygen supply, greater than normal, with low blood sugar and stillbirth.

& # 39; Our belief is that it would not be ethically correct to continue & # 39 ;, the researchers said The Guardian.

Maria Lärka and Christer Nilson, who participated in the study, told it Swedish TV4 that their baby died the day before the due date assigned to them by the researchers.

& # 39; If the birth had started a week earlier … you don't have to plan the funeral, & # 39; said Lärka.

Nilson added: & # 39; It feels pretty grotesque, like a lottery with human lives. & # 39;

A pregnancy is considered complete if the due date of a woman occurs after 40 weeks or 280 days.

Scientists agree that there is little to no risk if a woman is a few days late or even a week late.

However, there are risks when a pregnant woman lasts longer than 41 weeks and six days (long-term pregnancy) or 42 weeks and thereafter (long-term pregnancy).

These include stillbirth, greater than average at birth, low oxygen supply, low blood sugar levels and low levels of amniotic fluid that can affect the baby's heartbeat, according to the Mayo Clinic.

There are also health problems that the mother may face, such as severe vaginal tears, postpartum bleeding and infections.

About 0.4 percent of pregnancies in the US are post-term, according to birth certificate data.

A VS. study Published last year in the New England Journal of Medicine, it was recommended that women should be given the option to cause labor after they hit week 40.

In the UK, the National Health Service provides work induction for women who are more than 42 weeks pregnant.

For the study, led by the Sahlgrenska University Hospital in Gothenburg, the team planned to follow more than 10,000 women in 14 hospitals that were more than 40 weeks pregnant

The women were divided into two groups, one half being induced after 41 weeks and the other half after 42 weeks.

& # 39; The aim of this study is to investigate whether personality, self-efficacy, pain catastrophic, psychosocial and demographic factors contribute to maternal outcomes after induction of work at 41 (weeks) compared to expected management and induction at 42 (weeks) ), & # 39; wrote the authors.

When the study was canceled in October 2018, the researchers had only succeeded in recruiting 2,700 pregnant women.

Moreover, it was in the group of women who were induced 42 weeks that resulted in the six deaths.

Two hospitals, including Sahlgrenska, said they are changing their policies because of the results of the study and will now wait no more than 41 weeks to cause work.

& # 39; We have waited for the scientific analysis to show that it is really true that there is a greater risk of waiting after two weeks & # 39 ;, said Nils Crona, operations manager for maternity care in Sahlgrenska, Sveriges Television.

& # 39; Now we are planning as soon as we can get started with offering induction to all women who will encounter week 41. & # 39;
