New Cases of Diagnosed Diabetes on the Rise

State-specific data provide glimpse into geographical differences

For Immediate Release: October 30, 2008

The rate of new cases of diagnosed diabetes rose by more than 90 percent among adults over the last 10 years, according to a study by the Centers for Disease Control and Prevention (CDC).

The data, published in CDC′s Morbidity and Mortality Weekly Report, show that in the past decade, the incidence (new cases) of diagnosed diabetes has increased from 4.8 per 1,000 people during 1995-1997 to 9.1 per 1,000 in 2005-2007 in 33 states.

“This dramatic increase in the number of people with diabetes highlights the increasing burden of diabetes across the country,” says lead author Karen Kirtland, Ph.D., a data analyst with CDC′s Division of Diabetes Translation. “This study demonstrates that we must continue to promote effective diabetes prevention efforts that include lifestyle interventions for people at risk for diabetes. Changes such as weight loss combined with moderate physical activity are important steps that individuals can take to reduce their risk for developing diabetes.”

The study used data from CDC′s Behavioral Risk Factor Surveillance System, and provides incidence rates of diabetes for 43 states and two U.S. territories. Only 33 states had data for both time periods, but 43 states collected data in 2005-2007.

State-specific, age-adjusted estimates of new cases of diabetes ranged from 5 per 1,000 people in Minnesota to 12.7 per 1,000 in West Virginia. The number of news cases was highest in Puerto Rico at 12.8 per 1,000. States with the highest age-adjusted incidence were predominately Southern states: Alabama, Florida, Georgia, Kentucky, Louisiana, South Carolina, Tennessee, Texas and West Virginia.

“This report documents the geographic distribution of new cases of diabetes and is consistent with previous studies showing an increase in new diabetes cases,” said Kirtland. “We must step up efforts to prevent and control diabetes, particularly in the Southern U.S. region where we see higher rates of diabetes, obesity and physical inactivity.”

CDC, through its Division of Diabetes Translation, funds diabetes prevention and control programs in all 50 states, including the District of Columbia, and seven U.S. territories and island jurisdictions. The National Diabetes Education Program, co-sponsored by CDC and the National Institutes of Health, provides diabetes education to improve treatment for people with diabetes, promote early diagnosis and prevent or delay the onset of diabetes.

FDA Creates Task Force on International Food Contamination

By Emily P. Walker, Washington Correspondent, MedPage Today
Published: October 31, 2008

GAITHERSBURG, Md., Oct. 31 -- Pointing to the hazards of melamine-containing products from China, the FDA said today it is creating an internal science and policy workgroup to keep a critical eye on the international food supply.

Detecting contamination in the increasingly international food supply is "a necessary job of the FDA," said Randall Lutter, Ph.D., the agency's deputy commissioner for policy, at a meeting of the agency's science board.

And after the melamine contaminations from China -- first in pet food last year, and more recently in milk -- it is vital to develop a strategy for identifying and preventing potential illnesses, he said. (See: FDA Finds Melamine in Asian Milk Drinks)

The workgroup will have the assignment of pinpointing companies that appear to be at a high risk for contaminating the food supply with chemicals.

"There is a fundamental need for us to understand better the economic incentives and cultural norms in other countries," said Dr. Lutter. This, he added, means recognizing when spiking the food supply with chemicals is likely when it means enough extra profit for a manufacturer so that it offsets any potential penalties.

During the recent melamine outbreak, FDA officials suspect that melamine may have been added to infant formula to inflate protein levels cheaply.

In some sectors of the food industry in China, manufacturers are paid by the amount of protein in a product. Melamine costs about $1.20 per each protein count per ton, while legitimate protein costs about $6 per protein count per ton.

Melamine, which is used in some pharmaceuticals, dyes, glues and plastics, is normally not harmful to humans, but when it commingles with cyanuric acid, it becomes insoluble and can cause kidney failure.

"The suggestion is that some clever scientist used a high-quality melamine that did not have cyanuric acid," said Dr. Lutter. "It was only later that the melamine was commingled with the cyanuric acid."

But "forecasting economic infiltration is hard," Dr. Lutter said, and food coming across U.S. borders is shipped from countries with disparate regulatory requirements.

The United States virtually eliminated problem of economically motivated contamination of food produced in its own borders, largely through the creation of the FDA, Dr. Lutter said.

"It's an old problem, but fortunately it was successfully remedied during the early part of the 20th Century," he said.

But then came globalization of the food market.

"It's a symbol that the world we lived in changed, and there is a new vulnerability," Dr. Lutter said.

President Bush signed an executive order last year to establish a task force that recently issued an import safety action plan, Dr. Lutter said.

Dr. Lutter declined to comment on the specifics of the workgroup, but said it will consist of FDA employees. It is unclear whether the workgroup will also monitor possible contamination of foreign drugs.

Halloween Candy: It's Not How Much Kids Eat, It's When

Prolonged exposure to acid in the mouth is the culprit, pediatric dentist says

THURSDAY, Oct. 30 (HealthDay News) -- Halloween and its avalanche of candy is coming, making it the worst time of year for children's teeth, right?

Not necessarily, says a dentist who contends that parents can make a big difference by monitoring when their kids eat their sweets.

"Parents need to know that frequency is far more important than amount when it comes to taking in" sugars, said Dr. Mark Helpin, acting chairman of Temple University's Department of Pediatric Dentistry. "It's not how much we eat but how often we eat these kinds of things that will place us at increased risk of dental decay and cavities."

Candy remains a huge part of Halloween for tens of millions of American kids and their candy-buying -- or candy-pilfering -- parents. The National Confectioners Association says 93 percent of children in the United States go trick-or-treating, and the group estimates that Halloween candy sales this year will top $2.26 billion.

But children -- and adults -- are less at risk of developing tooth decay if they eat sweets -- or even carbohydrate-heavy foods like potato chips and crackers -- at mealtimes, Helpin said.

Cavities are most likely to develop when your mouth is exposed to the acid created by bacteria during eating, Helpin said. "When we eat [at meals], the flow of saliva increases. We're also taking in other liquids that will help wash the mouth out," he said.

But if you snack during the day, the teeth are continuously bathed in acid, he said. "If I have four pieces of candy, and I eat all four at one time, my mouth will have acid in it for 30 to 60 minutes. If I eat one each hour, my mouth can be exposed to acid for four hours," he added.

So what should you do? The worst time to give kids sweets is right before bedtime, Helpin said. As for mealtimes -- like lunchtime at school -- it's wise for children to swish a liquid in their mouths to wash away acid, he said.

When it comes to Halloween, Helpin recommends that parents not get overly concerned about candy and their kids. "I don't think Halloween week is going to be the make-or-break factor in whether someone will get a number of new cavities," he said.

Helpin recommends that parents have their kids brush their teeth after eating candy. If that's not possible, have them rinse their mouth with water three or four times after eating. This will help cut down on acidity in the mouth, he said.

There can be special concerns about Halloween treats if your child is among the 3 million American boys and girls with food allergies.

"Candy products frequently include ingredients like peanuts, tree nuts, milk and egg, some of the most common food allergens in children," Dr. Jacqueline A. Pongracic, an official with the Milwaukee-based American Academy of Allergy, Asthma & Immunology, said in a news release issued by the organization. "Peanuts and tree nuts are common causes of severe, life-threatening reactions, and children and their parents need to be aware of this and check ingredients for all treats. This can be especially tricky with Halloween candies, which often do not have ingredients listed on their labels."

According to the AAAAI, parents of children with food allergies should do the following:

Before Halloween, ask your neighbors to give out safe snacks, even distributing some to them to hand out specifically to your child.
Be aware that the smaller candy bars usually passed out to trick-or-treaters may have different ingredients than their regular-size counterparts.
Teach your child to politely refuse offers of home-baked goodies like cookies or cupcakes.

Workout regimens you can live with

NO LOITERING Exercise classes are a good way for older adults to meet new federal guidelines on exercise; children should get 60 minutes of activity daily. Weights increase intensity of training.

By JOHN HANC
Published: October 22, 2008
SWIM, bike, run, rake leaves. Climb monkey bars if you’re a child, do water aerobics if you’re older. Do whatever you like. Just keep moving.

What is different is the emphasis on the variety of activities — including daily chores — that can reap the profound health benefits of exercise.

There is no “one size fits all.” Instead, the guidelines are broken into specific recommendations for adults, children, people over 65 and others. And while sustained aerobic activities are the foundation, there are other types of activities — muscle-building and flexibility-enhancing — that are also important.

Here are some ideas on filling your own exercise prescription.

For the Time-Crunched

Can’t find five days a week to exercise? Train three days instead, but pick up the pace. Richard Cotton, an exercise physiologist with the American College of Sports Medicine, recommends a Wednesday-Saturday-Sunday routine. That way, he said, “you’re only getting into one of your workdays, but you don’t have any more than two days off at a time.”

Training for 30 minutes three times a week may fall short of the 150-minute goal, but the guidelines allow for as little as 75 minutes of exercise a week, provided the activities are higher in intensity. Mr. Cotton called that high-return-on-investment activity, and suggested using interval training to achieve it. Here’s how:

After a five-minute warm-up (on a treadmill or stationary bike, in a pool or even walking or jogging around a park), pick up the pace for five minutes, then go a little easier for three minutes. Repeat that pattern for the rest of the 30 minutes, making sure to end with an easy-effort, three- to four-minute cool-down. On an intensity scale of 1 to 10 (with 1 being the easiest effort, and 10 being all-out), your hardest intervals should be at 7 to 8, and recoveries at 5 to 6.

The same is true with strength training. Work the major muscles groups during at least two sessions a week. Mr. Cotton said you can begin to meet that part of the guidelines through a 10-minute workout using just three bodyweight exercises — abdominal crunches, back extensions and push-ups. For details on the program, visit www.myexerciseplan.com/assessment. Look for the Basic Bodyweight Strength Plan under “Keep It Simple.”

The Older Set

Older adults should try to get in 150 minutes of moderately intense activity and at least two sessions of strength training a week. You can accumulate those minutes by walking or joining an exercise class for older adults. For strength training, work with resistance bands, do bodyweight exercises or just climb stairs.

One key change in these guidelines is the stipulation that older adults should do exercises to maintain or improve their balance and to help avoid falls. Walking backward or on your toes can do that. In her forthcoming book, “Fitness After 40” (Amacom), Dr. Vonda Wright of the University of Pittsburgh Medical Center recommends a body movement that she calls “the stork.” Stand with your feet slightly apart. Raise one knee, while keeping your arms to the sides or your hands on your hips. Hold for 30 seconds, then switch legs. Repeat. If you have trouble at first, place your fingertips on a hard surface until you can balance.

For Children

The guidelines stipulate at least 60 minutes a day of moderate or vigorous activity for children from the ages of 6 to 17. That may sound like a challenge for parents whose children seem to prefer Xbox to exercise. But Stephen J. Virgilio, chairman of the physical education department at Adelphi University in Garden City, N.Y., said that is an obstacle that can be overcome.

“Research shows that when kids are given the opportunity to be physically active, they will be,” Dr. Virgilio said. “It’s up to adults to create that opportunity.”

But don’t expect your children to work out the way you do. “Children are intermittent learners and intermittent exercisers,” said Dr. Virgilio, author of the book “Active Start for Healthy Kids” (Human Kinetics). “They tend to start and rest and then start up again.”

Children can accumulate exercise minutes in various ways over a typical day. A younger child could walk to school and back (20 minutes), kick a ball around after school (20 minutes), climb the monkey bars on the playground (10 minutes) and ride a bike with friends (10 minutes).

Food allergies up 18% among U.S. children

Reactions lead to higher risk for asthma, other respiratory problems, CDC report says

Wednesday, October 22, 2008

WEDNESDAY, Oct. 22 (HealthDay News) -- The number of American kids with food allergies has soared 18 percent in the last decade, with an estimated 4 percent of children and teens now affected with the condition, a new federal report says.

In 2007, approximately 3 million children under the age of 18 were reported to have had a food or digestive allergy in the previous 12 months, compared to slightly more than 2.3 million children (3.3 percent) in 1997, according to the report from the U.S. Centers for Disease Control and Prevention.

Eight types of foods account for 90 percent of all food allergies -- milk, eggs, peanuts, tree nuts, fish, shellfish, soy, and wheat. Allergic reactions to these foods can range from a tingling sensation around the mouth and lips, to hives and even death, depending on the severity of the reaction, the report's authors said.

The report also said that children with food allergies are two to four times more likely to have asthma or other allergies, compared to children without food allergies.

It's not really known how a person develops a food allergy. They are more common in children than adults, and the majority of children with food allergies will "outgrow" them as they get older. But for some, a food allergy can become a lifelong concern, the report said.

Other highlights in the report:

Rates of food allergy were similar for boys and girls -- 3.8 percent for boys and 4.1 percent for girls.
Approximately 4.7 percent of children younger than 5 years of age had a reported food allergy, compared to 3.7 percent of children and teens aged 5 to 17 years.
Hispanic children had lower rates of reported food allergy (3.1 percent) than non-Hispanic white (4.1 percent) or non-Hispanic black children (4 percent.)
In 2007, 29 percent of children with food allergies also had reported asthma, compared to 12 percent of children without food allergy. And an estimated 27 percent of children with food allergies had reported eczema or skin allergy, compared to 8 percent of children without food allergies.
Slightly more than 30 percent of children with a food allergy also had reported respiratory allergy, compared with 9 percent of children with no food allergy.
From 2004 to 2006, there were approximately 9,537 hospital discharges annually for children from birth to 17 years of age who were diagnosed with a food allergy. Hospital discharges with a diagnosed food allergy increased significantly from the period 1998-2000 to 2004-2006. This finding could owe to increased awareness, reporting, and use of specific medical diagnostic codes for food allergies. Or it could represent a real increase in children who are experiencing food-allergic reactions.
The findings in the report, titled Food Allergy Among U.S. Children: Trends in Prevalence and Hospitalizations, were derived from statistics from the National Health Interview Survey and the National Hospital Discharge Survey, both conducted by CDC's National Center for Health Statistics.
