Women who do two or more night shifts a week during pregnancy are likely to have an increased risk of miscarriage, says a new study.
This is because women working at night are exposed to artificial light which disrupts their circadian rhythm or body clock and decreases the release of melatonin — a hormone that regulates sleep-wake cycles and helps in maintaining a successful pregnancy, according to the study published in the Occupational and Environmental Medicine journal.
The findings showed that after the eighth week of pregnancy, women who had worked two or more night shifts had a 32 per cent higher risk of miscarriage compared with women who had not worked any night shifts.
“This may be explained by the decline in the proportion of chromosomally abnormal foetuses with gestational age, which makes an association with environmental exposure more easily detectable among later miscarriages,” said researchers from the Bispebjerg and Frederiksberg Hospital in Denmark.
This is an observational study, and as such, cannot establish cause.
Previous studies have also stated that women who work in night shifts, even occasionally, are at an increased risk of early menopause, which can heighten the possibility of developing cardiovascular disease, osteoporosis and memory problems.
For the study, the researchers included nearly 23,000 pregnant women. (IANS)
Researchers have found that even five years down the line after having an abortion, over 95 per cent of the women said it was the right decision for them.
Published in the journal Social Science & Medicine, the study found no evidence that women began to regret their decisions as years passed.
On the contrary, the women reported that both their positive and negative feelings about the abortion diminished over time. At five years, the overwhelming majority (84 per cent) had either positive feelings, or none at all.
“Even if they had difficulty making the decision initially, or if they felt their community would not approve, our research shows that the overwhelming majority of women who obtain abortions continue to believe it was the right decision,” said study researcher Corinne Rocca, Associate Professor at University of California in the US.
“This debunks the idea that most women suffer emotionally from having an abortion,” Rocca added.
For the findings, the researchers analysed data from the Turnaway Study, a five-year effort to understand the health and socioeconomic consequences for nearly 1,000 women who sought abortions in 21 states around the country.
The analysis included 667 participants who had abortions at the start of the study. The women were surveyed a week after they sought care and every six months thereafter, for a total of 11 times.
While women did not report regretting their decision, many did struggle initially to make it. Just over half said the decision to terminate their pregnancy was very difficult (27 per cent) or somewhat difficult (27 pe rcent), while the rest (46 percent) said it was not difficult.
About 70 per cent also reported feeling they would be stigmatised by their communities if people knew they had sought an abortion, with 29 per cent reporting low levels and 31 percent reporting high levels of community stigma. Those who struggled with their decisions or felt stigmatized were more likely to experience sadness, guilt and anger shortly after obtaining the abortion.
Over time, however, the number of women reporting these negative emotions declined dramatically, particularly in the first year after their abortion. This was also true for those who initially struggled with their decision.
And relief was the most prominent emotion reported by all groups at the end of the study — just as it was at every time point in the study.
“This research goes further than previous studies, in that it follows women for longer, and was conducted on a larger sample from many different clinics throughout the US,” said Julia Steinberg from University of Maryland.
“It shows that women remain certain in their decision to get an abortion over time. These results clearly disprove claims that regret is likely after abortion,” Steinberg said. (IANS)
