Children with attention-deficit/hyperactivity disorder (ADHD) can perform better at school if placed on long-term drug therapy, a new study suggests. … “This study provides reassuring evidence that medication is not just blunting hyperactivity or enhancing alertness but actually doing so in a way that protects the capacity to learn,” noted Dr. David Katz, director of the Prevention Research Center at Yale University School of Medicine in New Haven, Conn.

Life expectancy rates in the United States are at an all-time high, with people born in 2005 projected to live for nearly 78 years, a new federal study finds. … Dr. David Katz, director of the Prevention Research Center at Yale University School of Medicine, said, “News that life expectancy is increasing is, of course, good. But the evidence we have suggests that there is more chronic disease than ever in the U.S. Diabetes and obesity are both epidemic, and of particular concern.

Some common food colorings and preservatives appear to increase the risk of hyperactive behavior among children, British researchers report. … “ADHD is an increasingly common problem, and theories abound to account for that,” said Dr. David Katz, director of the Prevention Research Center at Yale University School of Medicine. “Among them is the notion that food additives induce hyperactivity.”Despite this apparent connection, Katz cautioned that the increasing number of children with ADHD cannot be blamed on food additives alone.

Rock and pop stars are more than twice as likely to die early compared with the general population, British researchers report. … Dr. David Katz, director of the Yale University School of Medicine’s Prevention Research Center, said the study findings should serve as a wake-up call for performers and their fans about the hazards that can accompany fame.

Most young U.S. children are getting their recommended vaccinations, but rates for teens are lagging, especially for some newer vaccines, U.S. health officials announced Thursday. “This is clear and compelling evidence that financial barriers to health care come at a high cost to society. In this case, children will get diseases we have the means to prevent. That is unconscionable,” said Dr. David Katz, director of Yale University School of Medicine’s Prevention Research Center.

A study released today in the Archives of Internal Medicine is the latest to put a dent in the theory that vitamins such as C, E and antioxidants such as beta carotene can reduce the risk of heart attack, stroke or other cardiovascular events. “Studies of nutrients for disease prevention all indicate that the active ingredient in a healthful diet is a healthful diet, and not some isolated nutrient we can put in a pill,” said Dr. David Katz, director of the prevention research center at Yale University.

Although the 2006-07 flu season was comparatively mild in the United States, it still claimed the lives of 68 children, and experts say more must be done to reduce the death toll. … “While waiting to see what this year will bring, we should all plan to roll our sleeves up and get vaccinated and in no way let our guard down,” said Dr. David Katz, director of Yale University School of Medicine’s Prevention Research Center.

Most 3- and 5-year-olds who taste-tested a variety of foods said they preferred the ones in the McDonald’s wrapper — even though the foods were exactly the same, a new study finds. … “This study demonstrates simply and elegantly that advertising literally brainwashes young children into a baseless preference for certain food products,” said Dr. David Katz, the director of the Prevention Research Center at Yale University School of Medicine, New Haven, Conn.

Misconceptions about cancer are rampant among Americans, a new study finds, including the mistaken notions that cancer deaths are on the rise and that air pollution is a greater cancer risk than smoking. “The public understanding of cancer risk suffers from important gaps and misconceptions,” said Dr. David Katz, director of the Prevention Research Center at Yale University School of Medicine. “In some cases, cancer risk is exaggerated; American women believe breast cancer is the leading cause of death among them, but heart disease kills fully 10 times as many women,” Katz said. He added, “Some potential risk factors, such as pesticide residues on foods, are exaggerated, while others, such as cigarette smoking or excessive sun exposure, don’t get the full respect they deserve.”

If your friends and family get fat, chances are you will too, researchers report in a startling new study that suggests obesity is “socially contagious” and can spread easily from person to person. Obesity experts not involved in the research said the results back up what they have suspected all along – that people look toward one another for what is an acceptable weight. “If you’re just a little bit heavy and everyone around you is quite heavier, you will feel good when you look in a mirror,” said Dr. David Katz, director of Yale University’s Prevention Research Center.

A review by researchers from the U.S. Food and Drug Administration published in the current issue of the Journal of the National Cancer Institute has found that there is very little scientific evidence for the anti-cancer properties of either tomatoes or lycopene. “It reaffirms what we keep learning over and over again,” said Dr. David Katz, director of the Prevention Research Center at Yale University School of Medicine. “There is no silver bullet in food. Dietary pattern influences health very powerfully. But that power does not tend to reside in a single food, and certainly not in a single nutrient. Lycopene joins the ranks of vitamin C, beta carotene, and vitamin E in this regard.”

Researchers have found that chocolate – dark chocolate – is good for your heart. They say it may stave off hardening of the arteries among smokers, and it has more antioxidants per gram than red wine, green tea or berries. The latest study on chocolate shows it may be better for you than you think and that some people may even want to eat chocolate for medicinal purposes. Dr. David Katz is a weight control specialist. He warns people not to eat too much of a good thing. “If you over indulge, then the benefits no longer win out.”

Adopting a heart-healthy lifestyle makes a difference, even if the change doesn’t come until middle age. “Healthy living is the most powerful medicine of all. It requires no prescription, and all of the side effects are beneficial, too. It can, admittedly, be tough at times to get there from here, but it’s well worth it, and anytime is a good time to start,” said Dr. David Katz, director of the Prevention Research Center at Yale University School of Medicine.

Diet experts voiced skepticism over new claims that aspartame poses a risk to the millions of people who consume it daily. Dr. David Katz, director of the Prevention Research Center at the Yale University School of Medicine, said, “If aspartame were going to cause a meaningful uptick in human cancers, we’ve had a natural experiment – namely, the continuous tracking of cancer trends by CDC – to show us that movement of the needle. To date, it has not been seen.”

As many as 1.2 million U.S. hospital patients may be infected each year with a virulent staph infection that’s resistant to antibiotics — a rate almost 10 times greater than previous estimates, a new study finds. One expert agrees that more needs to be done to fight this looming threat. “In the early years of the 21st century, we are seeing the value of antibiotics decline as more and more germs become resistant to them,” says Dr. David Katz, the director of the Prevention Research Center at Yale University School of Medicine. “Methicillin-resistant Staph aureus is one important example of this trend.”
