EARLY TO BED: Parents now have another reason to send children to bed early. 

A US study found that pre-schoolers who are in bed by 8pm are half as likely to become obese teenagers as those who go to bed an hour later.

The study is based on data from 1,000 children who were followed from the ages of 4 to 15. 

Only 10% of four-year-olds who went to bed before 8pm became obese in their teenage years compared to 16% of those who turned in between 8pm and 9pm, and 23% of those who stayed up until after 9pm.

“Putting children to bed early is something concrete families can do to lower their child’s risk and it’s also likely to have positive benefits for their social, emotional and cognitive development,” said the study’s lead author Sarah Anderson of Ohio State University.

FISH OILS: Bowel cancer patients with a lot of omega-3 in their diets from oily fish might live longer, the new study published online in the journal Gut found.

Previous research has suggested that omega-3 polyunsaturated fatty acids (PUFAs) — namely, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and docosapentaenoic acid (DPA) — can suppress the growth of cancer tumours and curb blood supply to cancer cells.

In the new US study, experts found that bowel cancer patients who consumed PUFAs of at least 0.3g per day from foods had 41% less chance of death from bowel cancer compared with those who consumed less than 0.10g per day.

PREVENTABLE STROKE: A new study involving Irish scientists has found that up to 90% of strokes are preventable. 

An analysis of 27,000 people worldwide identified ten potentially modifiable risk factors for stroke. 

Here in Ireland, approximately 10,000 people a year suffer a stroke. 

Two thousand die and thousands more are left with disabilities.

The researchers calculated the population attributable risk (PAR) for each risk factor. 

High blood pressure was the biggest risk, with a PAR of 48%. 

Physical inactivity came in at 35%, lipids in the blood 26%, and poor diet 23%. 

Obesity stood at 18%, smoking, 12%, alcohol and stress at 6% and diabetes at 4%.
