To get an extra 14 years of life, don't smoke, eat lots of fruits and vegetables, exercise regularly and drink alcohol in moderation.
That's the finding of a study that tracked about 20,000 people in the United Kingdom.
Kay-Tee Khaw of the University of Cambridge and colleagues calculated that people who adopted these four healthy habits lived an average of 14 years longer than those who didn't.
"We've known for a long time that these behaviors are good things to do, but we've never seen these additive benefits before," said Susan Jebb, head of Nutrition and Health at Britain's Medical Research Council, which helped pay for the study.
Those Type A go-getters aren't the only ones stressing their hearts. Nervous Nelsons seem to be, too. Researchers reported Monday that chronic anxiety can significantly increase the risk of a heart attack, at least in men. The findings add another trait to a growing list of psychological profiles linked to heart disease, including anger or hostility, Type A behavior, and depression.
"There's a connection between the heart and head," said Dr. Nieca Goldberg of the New York University School of Medicine, a spokeswoman for the American Heart Association who wasn't involved in the study.
"This is very important research because we really are focused very much on prescribing medicine for cholesterol and lowering blood pressure and treating diabetes, but we don't look at the psychological aspect of a patient's care," she added. Doctors "need to be aggressive about not only taking care of the traditional risk factors ... but also really getting into their patients' heads."
Low levels of vitamin D, a chronic problem for many people in northern latitudes areas such as Wisconsin and Washington, were associated with substantially higher rates of heart disease and stroke, according to a new study.
In one of the strongest studies to date linking the vitamin to cardiovascular disease, researchers followed 1,739 members of the Framingham Offspring Study for more than five years.
They found the rate of cardiovascular disease events such as heart attacks, strokes and heart failure were from 53 percent to 80 percent higher in people with low levels of vitamin D in their blood.
"This is a stunning study," said John Whitcomb, medical director of the Aurora Sinai Wellness Institute in Milwaukee. He was not involved in the study.
Young people who start smoking may be influenced to do so by movies they saw in early childhood, new research suggests.
What's more, the study found that almost 80 percent of the exposure to smoking scenes in movies came through films rated "G," "PG" and "PG-13."
"Movies seen at the youngest ages had as much influence over later smoking behavior as the movies that children had seen recently," said study author Linda Titus-Ernstoff, a pediatrics professor at Dartmouth Medical School.
"And I'm increasingly convinced that this association between movie-smoking exposure and smoking initiation is real," she added. "That's to say, causal. It is quite improbable that the association we see is due to some other influence, some other characteristic inherent in children or parental behavior. The relationship is clearly between movie-smoking and smoking initiation."
France, Japan and Australia rated best and the United States worst in new rankings focusing on preventable deaths due to treatable conditions in 19 leading industrialized nations, researchers said on Tuesday.
If the U.S. health care system performed as well as those of those top three countries, there would be 101,000 fewer deaths in the United States per year, according to researchers writing in the journal Health Affairs.
Researchers Ellen Nolte and Martin McKee of the London School of Hygiene and Tropical Medicine tracked deaths that they deemed could have been prevented by access to timely and effective health care, and ranked nations on how they did.
They called such deaths an important way to gauge the performance of a country's health care system.
China defended its fish farming industry on Tuesday and said it was making progress in curbing use of illegal additives, from pesticides to banned steroids, as the country's food safety record remains in the spotlight.
China has suffered a rash of scares over the safety of its food and manufactured products in the last year which highlighted shoddy oversight and prompted a wave of new regulations and clean-up campaigns from the central government.
Vice Minister of Agriculture Gao Hongbin said the country had made encouraging progress.
Those who perceived they had low subjective social status had a 69% increased odds of having a 2-unit increase in BMI (this is around 11 pound weight increase).
The results were adjusted for a large number of factors including age, race/ethnicity, baseline BMI, diet, television viewing, depression, global and social self-esteem, menarche, height growth, mother's BMI, and pretax household income.
The study highlights yet another piece in the very complex obesity puzzle.
A 2004 study in the journal Science raised concern among fish lovers with news that farm-raised salmon, the type found at most supermarkets, contained higher levels of cancer-causing pcbs than wild salmon. (Banned in the 1970s, PCBs still contaminate the environment. They are released by incinerators and toxic waste sites.) But two more recent studies, one on farm-raised salmon and the other on wild, found that both harbor similar levels of this pollutant. The first study, done with Chilean- and Canadian-farmed salmon, found an average of 11.5 parts per billion PCBs. The second, conducted by the Alaska Department of Environmental Conservation, sampled 600 wild salmon from the Gulf of Alaska and the Bering Sea, and found 8.2 to 10 parts per billion PCBs. It's important to realize that the amount of PCBs being talked about is very small, says Cornell University seafood specialist Ken Gall, who has studied fish safety issues for 22 years. "High doses of PCBs, like the kind of contamination that occurs with an industrial accident, can be dangerous," Gall says. "But it's uncertain whether the tiny amounts of PCBs found in many foods such as fish, meat, or milk can cause cancer."
