FAT KIDS 'MORE LIKELY TO SUFFER A STROKE AT A YOUNG AGE'

FAT KIDS ‘MORE LIKELY TO SUFFER A STROKE AT A YOUNG AGE’

Fat children are more likely to suffer a stroke before the age of 55, warns new research.

The study shows high child body mass index (BMI) and gain in BMI increases the risk of early stroke in adulthood.

The research, presented at the European Obesity Summit in Sweden, shows that a high BMI in childhood, and also gains in BMI, are associated with an increased risk of early stroke in adults for both men and women.

Scientists say adult BMI is associated with ischemic stroke, especially at younger ages, but the association between childhood BMI and ischemic stroke in adulthood is unclear.

The researchers aimed to investigate if childhood BMI and gain in BMI during childhood are associated with the risk of early and late adult ischemic stroke.

They studied 307,677 Danish school children born from 1930 to 1987 who had weight and height measurements taken at age seven through 13.

BMI was calculated and transformed to ‘z-scores’ – a method for comparing how large a child is compared to a reference population.

They then identified ischemic stroke events by linkage to national registers and categorised them as early (25 to 55 years old) or late (over 55) events. The effects of BMI and gain in BMI between ages seven and 13 were estimated.

During a total of 8,128,058 person-years of follow-up, 3,529 women and 5,370 men had an ischemic stroke.

The researchers found both men and women with a childhood BMI z-score above average had an increased risk of early, but not late, ischemic stroke.

The pattern of the associations with early ischemic stroke were similar at all ages in childhood, but strongest at age 13, where a BMI z-score of one increased the risk of early stroke by 26 per cent in women and 21 per cent in men.

To put the findings in perspective, compared to an average height and weight child born in the late 1950s, a girl of the same height but who weighed 6.8 kilos (15 lbs) more would have a 26 per cent higher risk of early ischemic stroke.

And a boy of the same height who weighed 5.9 kilos (13lbs) more would have a 21 per cent higher risk of early ischemic stroke.

A BMI z-score gain of 0.5 from age seven to 13 was also associated with an about 10 per cent increased risk of early ischemic stroke in both women and men.

Dr Line Klingen Haugaard, of the University of Copenhagen in Denmark, said: “In this large prospective study we found that having a BMI above average in childhood as well as a BMI gain during childhood increases the risk of early adult ischemic stroke.

“Future research should address pathways through which these risks arise.”

Dr Haugaard added: “The results of this study highlight the potential effects that childhood overweight and obesity on the early development of atherosclerosis as well as other factors such as hypertension and type 2 diabetes, which are risk factors for ischemic stroke.”

    Pregnant women with whose blood pressure is even slightly raised can be dramatically more at risk of developing diabetes or heart disease, say scientists. In the first study of its kind a condition called pre-hypertension - where blood pressure is in the upper range of normal - has been shown to be potentially dangerous. Up to one-in-seven expectant mothers in the UK already suffer high blood pressure and the discovery could lead to many more requiring monitoring. Professor Jian-Min Niu, of Guangdong Women and Children Hospital in China, said: "Our findings underscore an important issue that has been long ignored in clinical practice - the fact criteria for hypertension in pregnancy are derived from the general population. "We anticipate if reaffirmed in further research, our study could spark a change in what we currently deem healthy blood pressure in pregnant women." The research found pregnant women whose blood pressure is in the upper ranges of normal could be at high risk of developing metabolic syndrome - a combination of diabetes, hypertension and obesity - and heart disease risk after giving birth. Current guidelines do not distinguish between pregnant women and the general population and define hypertension as persistently elevated blood pressure that is 140 millimeters of mercury (mm Hg) systolic or 90 mm Hg diastolic and above. Readings of 120-139 mm Hg systolic over 80-89 mm Hg diastolic is deemed 'pre-hypertension' - a warning sign of high blood pressure in the future. But the study published in Hypertension said pregnant women with blood pressure in this range had 6.5 times greater odds of developing metabolic syndrome compared to those in the lower normal range. It looked at 507 Chinese women with uncomplicated pregnancies, no history of hypertension and normal blood sugar and cholesterol who underwent seven or more blood pressure measurements along with other standard tests including weight measurements and foetal ultrasounds. Blood sugar and cholesterol levels were also tested at the start, shortly before and after giving birth and once every few months for up to 1.6 years after giving birth. The participants were grouped into three categories including those whose blood pressure remained on the lower end of normal (34%), around the mid-point (52%) or in the pre-hypertension range (13%). A series of snapshot measurements did not predict future risk but patterns of repeated elevations did - highlighting the dynamic nature of blood pressure during pregnancy. The results support the idea of pregnancy as a cardiovascular stress test for women that can reveal underlying disturbances in blood pressure regulation, glucose and cholesterol metabolism. Abnormalities in all three areas can disrupt functions and lead to full-blown cardiovascular disease years down the road. Prof Niu said globally the burden of cardio-metabolic diseases in women has been rising steadily over the last decades. He said: "Blood pressure measurements are already done as matter of routine and cost-effective checkups during pregnancy so our findings underscore this tool's potential to gauge a woman's post-partum cardiovascular risk. "Early identification of metabolic risk factors and implementation of lifestyle modifications may help delay the onset of cardiovascular disease that would present itself 20 to 30 years after delivery."
