Obesity in young adults can lead to pancreatic cancer
MD Anderson researchers compared 841 pancreatic cancer patients with 754 healthy people and found those overweight between 14 and 19 were 60 percent more likely to develop the cancer, while obesity in the 20s and 30s doubled or tripled the risk.

Majority of cancer patients use antioxidants to fight cancer
Among 663 Long Island women with breast cancer, 60.5 percent used antioxidants such as vitamins C and E, beta-carotene and selenium during conventional treatment, and 69.3 percent of those exceeded a multivitamin's dose. Whether antioxidants blunt radiation and chemotherapy remains contested.

Married Seniors More Likely to Seek Preventive Care
A survey of just over 13,000 people older than 65 found those living with a spouse more likely to get flu shots, colorectal screening, checkups and dental care than seniors living alone or with an adult child. Researchers could not explain the gap.

Morbidity and Mortality Related to Tobacco Use
Fact-sheet figures on smoking: tobacco kills more than 5 million people a year worldwide and about 443,000 in the United States, where smoking costs over $193 billion a year and roughly 19.8 percent of adults still smoke.

Americans ditch “healthy lifestyle”
Comparing two National Health and Nutrition Examination Survey samples 18 years apart, researchers in the American Journal of Medicine found only 8 percent of adults aged 40 to 74 kept all five healthy habits, down from 15 percent, while obesity rose from 28 to 36 percent.

Longer, slower walks most beneficial for heart health
In a Circulation study, 74 coronary patients assigned to walk 45 to 60 minutes 5 to 6 days a week lost 18 pounds, against 8 in standard rehab, and gained in cardiac function, fat loss, insulin sensitivity, blood pressure and cholesterol.

Exercise doesn’t boost metabolism long
Research by Dr. Edward Melanson at the University of Colorado found that moderate exercise of under an hour has little effect on 24-hour fat oxidation. If you replace the calories you burn, he said, you are no better off for fat loss than if you had not exercised at all.

Is detoxing necessary to a healthy lifestyle?
Mintel counted 54 new detox products in 2008. The Cleveland Clinic's Tanya Edwards says changing your diet accomplishes the same thing far less drastically, and a Navy internist quoted here calls the industry close to fraud; most regimens act as laxatives.

Massage after exercise impairs blood flow
Queen's University researchers report that massage after exercise impairs blood flow to the muscle and so hinders lactic acid removal, the opposite of what physical therapists commonly assume. They call theirs the first study to rigorously test the claim.

European study verifies cardio benefits of daily exercise in school children
After a year of daily school exercise in Leipzig, Germany, 188 students showed higher HDL cholesterol, lower systolic blood pressure and 29% greater endurance capacity, and the obesity rate fell from 13% to 9%. Researchers plan to follow the children for 10 to 20 years.

"Love Hormone" helps smooth relations
Swiss researchers gave couples oxytocin or placebo by nasal spray before a laboratory conflict discussion. The hormone increased positive communication and lowered salivary cortisol compared with placebo, though the study's author urges caution about wider claims for it.

Craigslist killer shows risk of erotic service lifestyle
The Philip Markoff case prompts a look at how sex work moved from strip bars to phone lines to the web. Each shift changed the risks rather than removing them, the writer argues, since the same pimps, con men and opportunists followed the women online.

Recession gardens take root
The National Gardening Association projects 45 million of 111 million US households will grow some of their own food this year, up 19 percent. It says the average garden yields 300 pounds of produce worth about $600, and organic gardeners rose from 5 million in 2004 to 12 million in 2008.

Laughter really is the best medicine
Dr. Lee Berk followed 20 people with diabetes who were on medication; half also watched 30 minutes of comedy a day. After two months that group had lower stress hormones, and by four months lower compounds tied to hardening arteries and higher good cholesterol.

Exercise could be the heart's fountain of youth
At Washington University in St. Louis, sedentary older adults who trained three to five days a week for about a year doubled their hearts' glucose uptake under drug-simulated exertion, as younger hearts do. By one metabolic measure, women benefited more than men.

55 minutes per day needed to sustain weight loss
Following 201 overweight and obese women eating 1,200 to 1,500 calories a day, University of Pittsburgh researchers found that sustaining a 10% weight loss over two years took about 55 minutes of exercise five days a week - well above the 150 minutes a week currently recommended.

Important precautionary advice on cell phone use
Ronald Herberman of the University of Pittsburgh Cancer Institute emailed colleagues an advisory on cell phone use, saying a growing body of studies links long-term use to possible harms including cancer, though the evidence remains controversial. France, Germany and India limit exposure.
