Having more children increases mums' risk of heart attack - study

Big families can increase health risk

The more children a woman has, the greater her risk of heart attack, stroke and heart failure, a study has shown.

Researchers at the University of Cambridge found that having five or more children is associated with a 40pc increased risk of a serious heart attack in the next 30 years, compared with having only one or two children.

Having five or more children was also associated with a 30pc increased risk of heart disease - the major cause of heart attacks - as well as a 25pc increased risk of stroke and a 17pc increase in the risk of heart failure.

Having three or four children was also associated with a modest increased risk of serious health implications, but the research found that the most significant risk increases were seen with five or more children.

The findings also suggest that the link between heart health and having children is independent of breastfeeding.

Jules Conjoice (48), from Pembrokeshire, Wales, has four children. She had a heart attack on New Year's Eve 2016.

"Although you might think it's unusual for women in their 40s to have a heart attack, I'm proof that it can happen to any of us," she said.

"It's frightening how many people have heart attacks and don't survive.

"As a busy mother, I'm always putting my family first, and looking after my health can take a back seat sometimes.


"I hope research like this brings it home to busy mothers and fathers that it's important to look after themselves as much as they care for their families."

The study, which is being presented at the British Cardiovascular Society Conference in Manchester, saw the team study data from more than 8,000 white and African-American women from the US, who were aged 45 to 64.

The University of North Carolina was also involved in the research.

They found that women who had a history of pregnancy loss but no children had a 60pc increased risk of heart disease and a 45pc increased risk of heart failure in the following 30 years, compared with women who had one or two live births.

They said this was likely to reflect underlying health problems that increase the risk of pregnancy loss as well as heart disease and heart failure.

Dr Clare Oliver-Williams, who led the research at the University of Cambridge, said: "The aim of my research is not to scare women but to bring to their attention as early as possible whether they might be at increased risk of heart attacks.

"We know that pregnancy and childbirth put a tremendous strain on the heart, and raising children can be very stressful too.

"We don't want to add to the stress people have in their everyday lives but equip them with the knowledge to do something about it. The number of children a woman has had is an easy sign of whether a woman is at greater risk.

"We all know it's hard to take care of your health when you have children, but hopefully this research can help show how important it is and, perhaps, having children can provide some extra motivation."

Prof Jeremy Pearson, of the British Heart Foundation, which funded the study, said: "Research like this reminds us that, regardless of the stereotype of the overweight, middle-aged man having a heart attack, heart disease strikes men and women alike.

"It's vital we continue to fund more life-saving research into heart disease to keep families together."
