Good news for gamers and parents—playing certain video games could actually count as exercise. New research shows that playing Wii Sports, if used correctly, could be the equivalent of a mild workout.

Sixteen volunteers, ages 20 to 24, took a fitness test to determine a baseline rating of perceived exertion (RPE).  Participants were instructed on proper usage of the game and played various Wii games while researchers monitored oxygen intake, heart rate and RPE.

The study, led by John Porcari, Ph. D., and Alexa Carroll, M.S., focused on six different activities—Free Run, Island Run, Free and Advanced Steps, Super Hula Hoop, and Rhythm Boxing.

Volunteers participated in each of the six activities randomly for 6 minutes. The Free and Island Run exercises required more energy, but neither used enough to meet the American College of Sports Medicine’s standard to affect cardio endurance.  The other activities fell below these health guidelines as well.

All of the activities did, however, burn calories. In 30 minutes, each activity burned the following number of calories:

• Free Step, 99 calories
  
• Advanced Step, 108 calories
• Super Hula Hoop, 111 calories
• Boxing, 114 calories
• Free Run, 165 calories
• Island Run, 165 calories

Although these exertion levels are significantly lower than doing similar exercise without the game, Wii Fit still used twice the calories of other video games. This is enough exertion to be considered a very mild workout.

“I guess anything is better than nothing,” Porcari says, “ but we were a little bit underwhelmed by the intensity of some of the exercises.”

An earlier study showed that certain Wii Sports activities burned more calories.

“You’re better off doing Wii Sports than Wii Fit,” Porcari explains. “In Wii Sports there’s more jumping around, and you’re not constrained by having to stand on the balance pad. I think there’s much more freedom of movement and you get a better workout.”

Thirty minutes each of Wii Sports activities burned the following number of calories:

• Wii Baseball, 84 calories
• Wii Golf, 93 calories
• Bowling, 117 calories
• Tennis, 159 calories
• Boxing, 306 calories

These findings could cut pounds for gamers in the long run, Carroll says, but it’s best not to rely on Wii alone. “Since using the Wii Fit alone may not produce results that meet recommended physical activity guidelines it is important that individuals participate in additional exercises to effectively reach these guidelines,” she says.

New software using cell phones may allow doctors to analyze coughs and diagnose respiratory illness, including pneumonia.

“A cough is one of the most common symptoms of illness and a common mode of disease spread,” says researcher Suzanne Smith, PhD, of STAR Analytical Services. “Yet we don’t use technology in any way to measure or understand what coughs mean.”

The program is designed to distinguish different coughs using acoustic vocalization analysis, a way to distinguish different audio tones. Researchers hypothesize that the sound of coughing varies by illness, and that these subtle differences may be enough to determine which illness a patient has.

If this is true, it could mean greater accessibility to medical services for individuals who live far from a doctor. An early diagnosis would also help determine what treatments are necessary and ensure that patients receive the proper medications they need to recover.

Efforts are currently focused on pneumonia,  a disease that kills 1.8 million children every year. Most of them live in developing countries. Software capabilities, if initially successful, are likely to grow. Cell phones could potentially be used to diagnose everything from the common cold to influenza.

The project is in its beginning stages, but the possibility of such a program could save millions of lives, not to mention billions of dollars in health care costs.

Dr. Tachi Yamada, president of the Global Health Program says that this is the exact sort of thinking it will take to tackle the world’s health challenges.

"I'm excited about their ideas and look forward to seeing some of these exploratory projects turn into life-saving breakthroughs," he says.

Adding just a little more fiber to your diet could help you drop pounds and shrink your waistline, according to weight research from the Keck School of Medicine at the University of Southern California.

“In the past decade, the decline in carbohydrate quality has been identified as a likely culprit leading to increased adiposity and metabolic disorders among children and adults,” authors write.

Eighty-five overweight Latino children from the Los Angeles area were asked to participate in the study. Selection criteria included having a family history of type 2 diabetes, likelihood of insulin resistance and pre-diabetes. The children were between the ages of 11 and 17, a stage when most begin developing eating habits. Researchers measured weight and body composition. The children then underwent two trial periods to monitor the effects of sugar and fiber intake.

The first trial lasted 16 weeks. Roughly one in three children who reduced their added sugar intake had improved insulin secretion. In this group, participants who consumed more fiber had a 10 percent reduction in visceral adipose tissue (body fat).

The second trial was based on 24-hour self-reported dietary recalls—two each year for two years. Although sugar intake didn’t have a significant effect, fiber continued to produce positive results.

“Although the healthy reputation of dietary fiber continues to grow, national data consistently show that children consume less than one-half of the recommended amount of dietary fiber,” authors write.

In addition to increasing insulin sensitivity, consuming more fiber appeared to lower body mass. An decrease in dietary and insoluble fiber intake increased fat tissue by 21 percent, compared with a 4 percent fat decrease in children who consumed more.

Those consuming more fiber ate more non-fried vegetables, fruit and legumes—all excellent sources of both dietary and insoluble fibers. Other sources include nuts and seeds, whole grains, and wheat bran.

The study provides great encouragement for individuals wishing to lose weight and improve metabolism. According to authors, even a small change could make a big difference:

"These findings suggest that fairly modest increases in fruit and vegetable intake of 1 or 2 servings and bean intake of 0.5 servings (equivalent to 1/4 cup) daily could have profound effects on lowering visceral adiposity and subsequent related metabolic disorders."

Certain types of antipsychotic medication can cause children to put on weight—as much as 18 pounds—according to research appearing in the Journal of the American Medical Association.

Dr. Chrostoph Correll, MD, and associates observed 272 children aged 4 to 19 taking atypical antipsychotic medication for the first time. Drugs/Medications included olanzapine (Zyprexa), quetiapine (Seroquel), risperidone (Risperadol) and aripiprazole (Abilify)—drugs sometimes used to treat children with autism, schizophrenia or bipolar disorder.

Children’s weights were monitored over a 12-week period. During the last two weeks of the study, nearly all experienced significant weight gain. Average gain was as follows: 18.7 pounds with onanzapine, 13.7 pounds with quetiapine, 11.7 pounds with risperidone, and 9.7 pounds with aripiprazole. Children in the control group gained less than half a pound (.44 pounds) on average.

“(E)ffects such as age-inappropriate weight gain, obesity, hypertension, and lipid and glucose abnormalities are particularly problematic during development because they predict adult obesity, metabolic syndrome, cardiovascular morbidity, and malignancy,” authors of the study write.

Doctors were so concerned over weight gain in children taking onanzapine that they stopped treatment before the study was completed. “Each antipsychotic was associated with significantly increased fat mass and waist circumference,” authors write. “Altogether, 10 percent to 36 percent of patients transitioned to overweight or obese status within 11 weeks.”

As more children—some younger than 5-years-old—are diagnosed with bipolar and “disruptive behavior” disorders (such as ADHD), there is also a rise in atypical antipsychotic prescriptions. These medications are generally effective for children with autism and schizophrenia, but they may not be the best treatment for other conditions.

The authors suggest seeking alternative treatments. They write that, in view of the negative health outcomes, the benefits of using these medications “must be balanced against their cardiometabolic risks”, and say the results suggest including in prescription guidelines closer monitoring during the early months of treatment.

They also plan on researching whether or not diet restrictions and additional medications for weight and glucose control will help balance the potential negative effects of the drugs.

There are likely to be plenty of ghosts and ghouls about this Halloween, but one thing that may have parents spooked this time of year is candy and dental health. Roughly 30 percent of 5-year-olds in Plymouth, England, were found to have some form of tooth decay, according to a newly released review.

The review examined the 2007-2008 dental records of U.K. children, 211 of whom were Plymouth five-year-olds. This number was just under the national average of 30.9 percent, but other regions were significantly worse.

The United States had similar rates. Almost half of children ages 12 to 15 and about one in four American children aged 2 to 5 is affected by tooth decay. Overall, it affects 4 million children in the U.S. alone. Americans consumed an average of 23.8 pounds of candy each in 2008, and with the holiday season approaching, parents should be on the watch for cavities.

As Halloween approaches, candy consumption is likely to skyrocket, but there are plenty of ways to protect trick-or-treaters from tooth decay. Try these five tips to help reduce the amount of sugar:

1. Choose reduced-sugar or sugar-free candies. Most stores carry equally tasty sugar-free or reduced-sugar versions of Halloween favorites, including chocolate, peanut butter cups and various filled or hard candies. These options won’t completely eliminate the risk of tooth decay, but they can significantly cut sugar intake.

2. Give out unconventional goodies. When it comes to candy, sugar-free gum is your safest bet. Candies that can melt and/or stick to teeth are the worst. Other ideas might include stickers, press-on tattoos, plastic rings, or other small toys.

3. Go to a Halloween program or event. Choosing alternatives to trick-or-treating significantly cuts the candy haul. These events are a great place for adults and children to socialize while enjoying snacks and fun activities.

4. Set a limit. Put a limit on the amount of candy a child is allowed daily. This helps prevent candy binges while reducing sugar consumption. Candy can also be used as a reward for good behavior.

5. Donate excess candy. Many communities have programs that will send it to troops or donate $1 for every pound of candy donated. Candy can also be donated to fire stations, schools (for rewards), or other offices in the community.

Regularly brushing teeth and reducing sugar intake can help prevent cavities. Consuming fewer sweets can also help decrease children’s risk for obesity and diabetes. Dentists and parents alike recommend that candy be consumed in moderation.

Legislators are considering the option of food taxes on sweetened beverages, including soda pop, and snack foods in an effort to battle obesity. Forty states are in support of a small tax on soda, while New York and Maine believe a higher tax may be necessary.

 
According to a report in The New England Journal of Medicine, sugar consumption has risen 30 percent over the last decade. For teens and children, soda accounts for 10-15 percent of total calories consumed. By removing just ¼ of the sugar in sweetened beverages, consumers can reduce annual caloric intake by 8,000 calories. This figure equates to roughly two pounds of weight in a year.

“Americans consume about 250 to 300 more calories daily today than they did several decades ago,” according to authors Kelly D. Brownell, Ph.D., and Thomas R. Frieden, M.D., M.P.H. “Though no single intervention will solve the obesity problem, that is hardly a reason to take no action.”

Such a high rate of sugar intake can do more than expand the waistline. It can also increase the risk of type 2 diabetes, heart disease, and other problems as a result of poor nutrition and weight gain. The objectives of those in support of a tax are twofold—to lower consumption, and to encourage soft drink producers to decrease the amount of caloric sweeteners in their products.

There are strong arguments on both sides. People arguing against the tax point out that food is necessary to survive. They believe raising prices will make it more difficult for low-income families to eat. Others argue that the poor would benefit the most. As the price of fresh produce and other healthier options goes up, soda and junk food prices are going down. People with tighter budgets consume more of the cheap but less nutritious foods and beverages.

“As Coca-Cola prices increased by 12 percent, sales dropped by 14.6 percent,” Frieden and Brownell wrote. Analysts believe that a 1 cent-per-ounce price increase could reduce consumption by as much as 10 percent. Justin Wilson, senior research analyst for the Center for Consumer Freedom, argues that such a tax is manipulation against the consumer. “The tax code should not be used as a method for social engineering, and that’s what this is,” he said.  Legislators see the issue a little differently.

Higher prices have been used effectively in the past to reduce tobacco sales, and any revenue from a tax on soda could raise up to $14.9 billion per year. This money could be used to support health reforms or other programs. New Yorkers’ support rose by 20 percent when lawmakers suggested using these funds for obesity prevention programs.

Seven in ten children in the United States are not getting enough vitamin D, according to the National Health and Nutrition Examination Survey (NHANES, 2001-2004).

Vitamin D, 25-Hydroxyvitamin D, is a fat-soluble vitamin that promotes calcium absorption, fortifying bones and teeth, and maintaining the level of calcium and phosphorus in the blood.

Vitamin D deficiency can result in conditions such as rickets in children (usually <11 ng/mL), and osteomalacia and osteoporosis in adults (typically levels <25 ng/mL). Low levels of vitamin D also increase the risk of bone and heart disease, and are also associated with higher blood pressure and lower calcium and HDL cholesterol levels in later life.

Based on the information obtained from the survey, researchers found that, of more than 6,000 of children followed, nine percent (equal about 7.6 million) were vitamin D deficient, and a greater number were found to be getting an insufficient amount—61%, representing 50.8 million U.S. children. Only 4% received the recommended daily amount of vitamin D.

Children classified as “insufficient” had 15-29 ng/mL, while those who were classified as “deficient” had levels of 15 ng/mLor less. Normal range, according to the National Institute of Health, is 30-74 ng/mL.

The study is the largest of its kind to date, gaining nationwide rather than just regional data. "We expected the prevalence of vitamin D deficiency would be high,” says lead author Juhi Kumar, M.D., M.P.H., of the Children's Hospital at Montefiore Medical Center, “but the magnitude of the problem nationwide was shocking."

Vitamin D deficiency is more common for female children, those that are older, obese, drink less than one glass of milk week, and those who spend four hours or greater on the computer or watching television per day. African-American and Mexican-American children also had a greater risk.“It’s very hard to get enough vitamin D from dietary sources alone,” says Dr. Michal Melamed of the Albert Einstein College of Medicine in Bronx, New York.

Melamed, co-leader of the study, attributes part of this problem to lifestyle, recommending parents send their children outdoors. One source of vitamin D is UV-B sunlight, which converts cholesterol in the skin into vitamin D. She also recommends ditching the sunscreen for a while: “Just 15 to 20 minutes a day should be enough…don't put sunscreen on them until they've been out in the sun for 10 minutes, so they get the good stuff but not sun damage.” Individuals with darker skin and those who live in northern regions with less sun exposure should spend more time outdoors.

The American Academy of Pediatrics recommends that children and teens get at least 400 IU per day, double the previous recommendation of 200IU per day. Good sources of vitamin D include fish, milk, eggs, cod liver oil, and fortified foods. Vitamin D levels can also be increased with the use of supplements.

The study's abstract is available online, and will be published in September's issue of Pediatrics.

 The air quality in and around your home may have negative effects on your child’s intelligence, according to a study by Columbia University Center for Children’s Environmental Health (CCCEH).

The study, released a week ago by the National Institute of Environmental Health Sciences (NIEHS), found that children exposed to chemical pollutants called polycyclic aromatic hydrocarbons found in the air, water, and soil scored lower on IQ tests than children with lower exposure.

Polycyclic aromatic hydrocarbons, or PAHs, are chemical pollutants that can be found in the air, water, and soil. PAHs are typically released from the burning of fossil fuels (coal, diesel, oil, gas, etc.), tobacco and other natural substances. Auto emissions are a major source of PAHs in the United States, especially in heavily trafficked urban areas.

Doctor Frederica Perera, lead author and professor of Environmental Health Sciences at Columbia University Mailman School of Public Health, compares the exposure to such pollutants to low-level lead exposure. “These findings are of concern because these decreases in IQ could be educationally meaningful in terms of school performance,” she says. “IQ is an important predictor of future academic performance.”

A child’s developing fetal and nervous system is more vulnerable than an adult’s, and PAHs have been associated with higher cancer risk, asthma, allergies, low birth weight, and a reduced head circumference. Reduced head circumference, according to CCCEH, is connected with lower cognitive functioning and academic performance. In this study, the first of its kind, researchers hoped to study the relationship of in utero PAH exposure on a child’s intelligence.
 
Participants were non-smoking black and Dominican-American women, aged 18-35, residing in Washington Heights, Harlem and South Bronx, N.Y.—areas with higher pollutant exposure. During pregnancy participants regularly completed questionnaires and were asked to wear monitors that measured PAH levels.

Researchers followed the children, measuring IQ levels at age three and again at age five using the Wechsler Preschool and Primary Scale of the Intelligence. Of the 249 children, 140 had higher than the average 2.26 n/m3 level of exposure. The mean score for all children was 98.72, with a mean score of 96.6 for children whose exposure was classified as “high” and 101.6 for children with lower exposure. Scores differed by 4.67 on the verbal and 4.31 points on the full-scale test.

Researchers will continue to follow children to age 11 to learn more about the effects of PAHs on intelligence and child development. “It should serve as a warning bell to us all,” says Linda Birnbaum, Ph.D., director of NIEHS. “We need to do more to prevent environmental exposures from harming our children.”

New laws in Louisiana, Connecticut, Georgia and Pennsylvania give students the right to carry and self-administer their own medications, including an asthma inhaler.
At this back-to-school time, find out how to tell if your child with asthma is ready to carry and use an inhaler on his or her own. Age and grade-level matter less than individual readiness, according to the Allergy&Asthma Network Mothers of Asthmatics (AANMA).

Parent/Child Asthma Inhaler Quiz
See how your answers to the following questions match up with your child’s answers. These are the best clues to determining your child’s readiness to self-manage asthma symptoms at school:

1. Does your child use an inhaler (preferably with a holding chamber) correctly at home? 

2. Does she know the name of her medication and when to use it? 

3. Does he stay calm when having asthma symptoms? 

4. Does she tell you when she is having symptoms or when she has used the inhaler? 

5. Does he use a peak flow meter? 

6. Does your child carry the inhaler at all times? 

7. Does he understand that the inhaler is not a toy and should not be shared with friends? 


If you and your child answer “Yes” to most of these questions, you have a child ready to learn about and take responsibility for his or her inhaler.
 
Asthma self-management begins at home. Parental instruction should be backed up by plenty of low-pressure practice. At school, teachers should be aware of the condition and supportive of the process.
Students who self-manage symptoms must be willing to notify teachers, the school nurse or designated administrator when they need to use their inhalers to treat symptom. They must be willing to tell their parents about all medication use or symptoms experienced while away from home.

Back-to-School Asthma To-Do List for Parents
Ensure that backup medication is available in the school clinic should the child become separated from his medication at any time.
Complete required forms and keep them updated during the school year if contact information or emergency treatment plans change.
 

Not yet time for self-use of an inhaler? School personnel will need to ensure that the student’s medication travels with him from one classroom to the next to prevent treatment delays in times of need. Your child’s allergy or asthma management plan should specify this.

It’s not always easy to find time to eat together, but a study published in the May issue of the Journal of Adolescent Health found that frequent family meals improve the eating habits and attitudes of middle school-aged children. Students who dined with their families six or seven times a week consumed fewer soft drinks, ate breakfast more often, ate more healthfully, and exhibited less concern about undue weight gain.

Researchers at the University of Waterloo in Ontario, Canada surveyed more than 3,000 Canadian sixth, seventh, and eighth graders during the 2004-2005 school year. The students completed the web-based Food Behaviour Questionnaire, which included questions about dining frequency, 24-hour food intake, and family meals.

The results showed that family meals became less common as children grew older, and families in rural areas were more likely to eat together than families in urban locales. Children who frequently dined with their families had significantly higher-quality diets than children who rarely ate with their parents and siblings. Diet quality declined when meals were purchased outside of the home or when meals were skipped.

The study also showed that most of the students surveyed had suboptimal diets. The researchers encourage dining as a family to promote healthful eating habits.
