Anaemia During Pregnancy Might Spike Up Risk of Heart Disease

They also found that high renal function at the end of pregnancy indicated a 1.5-fold increased risk of cardiovascular disease

Gestational anaemia — lack of blood — in pregnancy may be a marker for cardiovascular disease (CVD) and stroke later, a study has found.

Simple blood tests during pregnancy may reveal cardiovascular disease and stroke, up to 25 years before the disease outbreak, said researchers from Soroka Medical Center and Ben Gurion University, in Israel.

In women with anaemia, CVD was 1.5 times higher than in women without anaemia. The rate of hospitalization for CVD was 4.35 per cent for women with gestational anaemia, compared to 3.7 per cent for the control group, the Xinhua reported.

The high risk of CVD was significant even after neutralising factors that might bias outcomes such as smoking, obesity, and hypertension disorders.

Among the diseases diagnosed in the pregnant patients are heart attacks, angina, heart failure, stroke, renal failure and hypertension with damage to internal organs.

The study reinforces the need for use of iron products, not necessarily for immediate results but also for long-term complications. The researchers also recommend women with a longer-term follow-up anaemia to prevent recurrence of heart and blood vessel diseases, researchers said.

For the study, the team followed about 30,000 women with anaemia who gave birth at Soroka hospital between 1988 and 2014. The control group was over 50,000 women who gave birth in those years and did not suffer from anaemia.

Among the blood tests found to be associated with a high risk of morbidity were creatinine and urea levels, a measure of kidney function, and potassium levels. (IANS)

Avoid Smoking During Pregnancy To Prevent Premature Births

The negative health impacts of cigarette smoking during pregnancy, including low birth weight, delayed intrauterine development, pre-term birth, infant mortality, and long-term developmental delays, are well known.

Expecting mothers, take note. As smoking during pregnancy is linked with negative health outcomes, a team of researchers has found that smoking cessation during pregnancy may reduce the risk of pre-term birth.

The findings, published in the JAMA Network Open journal, showed that the probability of pre-term birth decreased with earlier smoking cessation in pregnancy — up to a 20 per cent relative decrease if cessation occurred at the beginning of pregnancy.

“Of concern, though, given the substantial benefits of smoking cessation during pregnancy is that the proportion of pre-pregnancy smokers who quit smoking during pregnancy has remained essentially stagnant since 2011,” said lead author Samir Soneji from The Dartmouth Institute for Health Policy and Clinical Practice in the US.

For the study, the researchers conducted a cross-sectional study of more than 25 million pregnant women who gave birth to live neonates during a six-year period — measuring their smoking frequency three months prior to pregnancy and for each trimester during pregnancy.

The negative health impacts of cigarette smoking during pregnancy, including low birth weight, delayed intrauterine development, pre-term birth, infant mortality, and long-term developmental delays, are well known.

But the good news is that the proportion of women who start their pregnancy as smokers has been declining in recent years, the researchers said.

However, the study also found that only about 25 per cent of women who smoked prior to pregnancy were able to quit throughout their pregnancy, and approximately 50 per cent of women who smoked during their pregnancy did so with high frequency (more than 10 cigarettes per day).

The researcher plans to look at quit rates and smoking intensity and their impact on the risk of infant mortality.

“Thankfully most premature babies end up doing well,” he said.

“But premature birth is strongly linked to infant mortality. If we determine quitting, and quitting early, reduces the risk of infant mortality, then that may speak to mothers even more saliently about the importance of smoking cessation,” he added. (IANS)
