Night Shifts During Pregnancy up Miscarriage Risk: Study

For the study, the researchers included nearly 23,000 pregnant women

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.

Consuming High- Fibre Diet may Reduce Risk of Preeclampsia During Pregnancy

Pregnancy outcomes and infant immunity are linked to gut bacteria

Ladies, please take note. Consuming a high-fibre diet may reduce the risk of preeclampsia during pregnancy, researchers have found.

“Simple recommendation to ‘eat real food, mostly plants and not too much’ might be the most effective primary prevention strategy for some of the most serious conditions of our time.

“The mother’s gut bacteria and diet appear to be crucial to promoting healthy pregnancy,” said study lead author Ralph Nanan, Professor at the University of Sydney.

The study, published in the journal Nature Communications, showed that pregnancy outcomes and infant immunity are linked to gut bacteria.

Plant-based fibre is broken down in the gut by bacteria into factors that influence the immune system. The research team investigated the role of these metabolic products of gut bacteria during pregnancy.

The researchers found that in humans, reduced levels of acetate, which is mainly produced by fibre fermentation in the gut, is associated with the common and serious pregnancy-related condition preeclampsia.

Preeclampsia occurs in up to 10 per cent of pregnancies and is characterized by high blood pressure, protein in the urine and severe swelling in the mother’s body.

It also interferes with the child’s immune development whilst in the womb, with some evidence suggesting a link to higher rates of allergies and autoimmune diseases later in life.

The study found that preeclampsia affected the development of an important foetal immune organ – the thymus – which sits just behind the breastbone.

Foetuses in preeclamptic pregnancies were found to have a much smaller thymus than children from healthy pregnancies.

The cells the thymus normally generates — called ‘T’ cells, and specifically those associated with the prevention of allergies and autoimmune conditions such as diabetes — also remained lower in infants after preeclampsia, even four years after delivery.

The mechanisms of acetate on the developing foetal immune system were further examined in separate experiments involving mice that showed acetate was central in driving foetal thymus and ‘T’ cell development.
