Kids With High IQs Live Longer

(HealthDay News) -- Children with high IQs live longer, but it is not clear exactly what role IQ plays in longevity, new British research shows.

Previous studies have shown an association between IQ and mortality, but an explanation for that has proved elusive. This is an important question because identifying those mechanisms would help in understanding the origins of health inequalities, the researchers said.

"The IQ-mortality association emerges already early in adult life, even when most life-threatening diseases are not yet that common," said lead researcher Markus Jokela, who is now with the department of psychology at the University of Helsinki, in Finland. "So the role of IQ is not only restricted to how people become ill or cope with their illnesses in old age."

The report is published in the Aug. 10 online edition of Pediatrics.

For the study, Jokela's team collected data on 10,620 men and women who participated in the 1958 British Birth Cohort Study and had their IQs tested when they were 11. Researchers followed these individuals until they were 46 years old. Read more...

Chips, Fries, Soda Most to Blame for Long-Term Weight Gain

(HealthDay News) -- The edict to eat less and exercise more is far from far-reaching, as a new analysis points to the increased consumption of potato chips, French fries, sugary sodas and red meat as a major cause of weight gain in people across the United States.

Inadequate changes in lifestyle factors such as television watching, exercise and sleep were also linked to gradual but relentless weight gain across the board.

Data from three separate studies following more than 120,000 healthy, non-obese American women and men for up to 20 years found that participants gained an average of 3.35 pounds within each four-year period -- totaling more than 16 pounds over two decades. Read more...

Gene Variant May Raise Death Risk After Heart Bypass

(HealthDay News) -- People who carry a certain genetic variant involved in blood clotting and inflammation have a lower five-year survival rate after coronary artery bypass surgery, researchers report.

The findings should be used to better treat and ensure the survival of these surgical patients over the long-term, said the research team from Duke University Medical Center in Durham, N.C.

"There are possibilities that we could apply this information someday to a patient's prognosis, and for careful monitoring or increased surveillance if a person has a 2.5 times higher risk of dying, instead of letting them go their way after a CABG [coronary artery bypass graft] surgery," study senior author Mihai Podgoreanu, an assistant professor of anesthesiology, said in a Duke news release.
