The Dept of Health and Human Services ran an article on HHS.gov about backpacks.This is what they want you to know about children and adults using backpacks.

Backpacks are a better option than shoulder or messenger bags for carrying books and supplies because the weight of the pack is evenly distributed across your body. However, backpacks that are overloaded or not used properly can make for health problems.

How Can Backpacks Cause Problems?

People who carry heavy backpacks sometimes lean forward. Over time, this can cause the shoulders to become rounded and the upper back to become curved. Because of the heavy weight, there’s a chance of developing shoulder, neck, and back pain.

If you wear your backpack over just one shoulder, or carry your books in a messenger bag, you may end up leaning to one side to offset the extra weight. You might develop lower and upper back pain and strain your shoulders and neck.

Not using a backpack properly can lead to poor posture.

Carrying a heavy pack increases the risk of falling, particularly on stairs or other places where the backpack puts the wearer off balance.

People who carry large packs often aren’t aware of how much space the packs take up and can hit others with their packs when turning around or moving through tight spaces, such as the aisles of the school bus. Students also are injured when they trip over large packs or the packs fall on them.

How Do You Know If a Backpack Is a Problem?

You may need to put less in your pack or carry it differently if:

• you have to struggle to get your backpack on or off
• you have to lean forward to carry your pack
• you have back pain

If you adjust the weight or the way you carry your pack but still have back pain or numbness or weakness in your arms or legs, talk to your doctor.

Tips for Choosing and Using Backpacks

• Consider the construction. Before you grab that new bag off the rack, make sure it’s got two padded straps that go over your shoulders. The wider the straps, the better. A backpack with a metal frame like the ones hikers use may give you more support (although many lockers aren’t big enough to hold this kind of pack).
• Carry it well. Before you load your backpack, adjust the straps so the pack sits close to your back. If the pack bumps against your lower back or your butt when you walk, the straps are probably too long. Always pack your backpack with the heaviest items closest to your back. Don’t drop all your stuff in the main compartment (using the side pockets will distribute the weight more evenly).
• Try a pack with wheels. Lots of kids use these as an alternative to backpacks, but there are guidelines and considerations to keep in mind with this kind of pack, too. Many schools don’t allow rolling packs because people can trip over them in the halls.
• Limit your load. Doctors and physical therapists recommend that people carry no more than 10% to 15% of their body weight in their packs. This means that if you weigh 120 pounds, your backpack should weigh no more than 12 to 18 pounds. Choosing a lightweight backpack can get you off to a good start. Use your bathroom scale to weigh your backpack and get an idea of what the proper weight for you feels like.
• Pick it up properly. As with any heavy weight, you should bend at the knees when lifting a backpack to your shoulders.

 The September 2014 edition of the Centers for Disease Control (CDC) Vital Signs focuses on the amount of sodium in children’s diets.

Reducing Sodium in Children’s Diets

Nearly 9 in 10 US children eat more sodium than recommended, and about 1 in 6 children has raised blood pressure, which is a major risk factor for heart disease and stroke. Lowering sodium in children’s diets today can help prevent heart disease tomorrow. Small changes make a big impact on your child’s daily sodium intake. Learn more in the current CDC Vital Signs.

Sources of Sodium

Americans get most of their daily sodium—more than 75%—from processed and restaurant foods.² What is processed food?

Sodium is already in processed and restaurant foods when you purchase them, which makes it difficult to reduce daily sodium intake on your own. Although it is wise to limit your use of added table salt while cooking and at the table, only a small amount of the sodium we consume each day comes from the salt shaker.

Dietary Guidelines for Sodium and Potassium

The Dietary Guidelines for Americans, 2010[PDF-2.9M] recommend that everyone age 2 and up should consume less than 2,300 milligrams (mg) of sodium each day. Some groups of people should further limit sodium intake to 1,500 mg per day, including:

• Adults age 51 or older.
• All African Americans.
• Anyone who has high blood pressure, diabetes, or chronic kidney disease.

Those groups add up to about half of the U.S. population and the majority of adults.

The Dietary Guidelines for Americans also recommend meeting the potassium recommendation (4,700 mg per day). Higher potassium intake can help lower blood pressure. Foods that are high in potassium and low in sodium include bananas, potatoes, yogurt, and dry beans, among others. The U.S. Department of Agriculture’s Sodium and Potassium fact sheet[PDF-153K] has more information about the role of potassium in a healthy diet and a list of foods rich in potassium.

Nearly everyone benefits from lower sodium intake. Learn more about sodium in your diet in Where’s the Sodium?, a February 2012 report from CDC Vital Signs.

Findings in a recent study, reported by Erin White in a Northwestern University press release, give us insight into why human children take so long to grow and develop. The findings are an interesting read about brain development!

EVANSTON, Ill, August 25, 2014. — A five-year old’s brain is an energy monster. A new study led by Northwestern University anthropologists has found that it uses twice as much glucose (the energy that fuels the brain) as that of a full-grown adult.

The study helps to solve the long-standing mystery of why human children grow so slowly compared with our closest animal relatives.

The study shows that energy funneled to the brain dominates the human body’s metabolism early in life and is likely the reason why humans grow at a pace more typical of a reptile than a mammal during childhood. Results of the study were published the week of Aug. 25 in the journal Proceedings of the National Academy of Sciences.

“Our findings suggest that our bodies can’t afford to grow faster during the toddler and childhood years because a huge quantity of resources is required to fuel the developing human brain,” said Christopher Kuzawa, first author of the study and a professor of anthropology at Northwestern’s Weinberg College of Arts and Sciences. “As humans we have so much to learn, and that learning requires a complex and energy-hungry brain.”Kuzawa also is a faculty fellow at the Institute for Policy Research at Northwestern.

The study is the first to pool existing PET and MRI brain scan data — which measure glucose uptake and brain volume, respectively to show that the ages when the brain gobbles the most resources are also the ages when body growth is slowest. At 4 years of age, when this “brain drain” is at its peak and body growth slows to its minimum, the brain burns through resources at a rate equivalent to 66 percent of what the entire body uses at rest.

The findings support a long-standing hypothesis in anthropology that children grow so slowly, and are dependent for so long, because the human body needs to shunt a huge fraction of its resources to the brain during childhood, leaving little to be devoted to body growth. It also helps explain some common observations that many parents may have.

“After a certain age it becomes difficult to guess a toddler or young child’s age by their size,” Kuzawa said. “Instead you have to listen to their speech and watch their behavior. Our study suggests that this is no accident. Body growth grinds nearly to a halt at the ages when brain development is happening at a lightning pace, because the brain is sapping up the available resources.”

It was previously believed that the brain’s resource burden on the body was largest at birth, when the size of the brain relative to the body is greatest. The researchers found instead that the brain maxes out its glucose use at age 5. At age 4 the brain consumes glucose at a rate comparable to 66 percent of the body’s resting metabolic rate (or more than 40 percent of the body’s total energy expenditure).

“The mid-childhood peak in brain costs has to do with the fact that synapses, connections in the brain, max out at this age, when we learn so many of the things we need to know to be successful humans,” Kuzawa said.

“At its peak in childhood, the brain burns through two-thirds of the calories the entire body uses at rest, much more than other primate species,” said William Leonard, co-author of the study. “To compensate for these heavy energy demands of our big brains, children grow more slowly and are less physically active during this age range. Our findings strongly suggest that humans evolved to grow slowly during this time in order to free up fuel for our expensive, busy childhood brains.” Leonard is professor and chair of the department of anthropology at Northwestern’s Weinberg College of Arts and Sciences.

This study was a collaboration between researchers at Northwestern University, Wayne State University, Children’s Hospital of Michigan, Icahn School of Medicine at Mount Sinai, University of Illinois, George Washington University and Harvard Medical School.

The title of the paper, which is published in the Proceedings of the National Academy of Sciences, is “Energetic costs and evolutionary implications of human brain development.” Authors include Kuzawa and Leonard as well as Harry T. Chugani, Lawrence I. Grossman, Leonard Lipovich, Otto Muzik, Patrick R. Hof, Derek E. Wildman, Chet C. Sherwood and Nicholas Lange.

The study was funded by the U.S. National Science Foundation’s Biological Anthropology Program.

Furniture that can tip is an accident waiting to happen. It a potential source of serious injury for a young child.

In a recent press release, Dr. Alex Rosenau, president of the American College of Emergency Physicians, spoke to the need to inventory our living space for potential sources of tipping and falling objects. He said, “Every parent or guardian of a young child should look around their homes and imagine what could tip over, fall off walls, and injure a child.  Imagining it is better than it becoming a reality.”

The nation’s emergency physicians handle tragic situations too often, but few things are more upsetting than the sudden death of a child killed by a piece of a furniture, appliance or a television falling on them.

About 43,000 people annually were treated in emergency departments between 2009 and 2011 as a result of objects tipping over (such as televisions, dressers, file cabinets, large appliances,) according to the Consumer Product Safety Commission.  Sixty-percent of those emergency visits were from children. In that time span 294 children died–ranging from one-month to 8-years-old.

How to Prevent  Furniture Injuries in Your Home:

• Properly secure all furniture (especially with shelves, drawers and doors) to walls and remove furniture that is top-heavy and cannot be secured.  Check with home improvement stores or child retail stores and ask experts what they recommend.
• Secure all computer monitors.
• Keep television and computer equipment low to the ground.
• Do not place any objects on top of a television.
• Place heavy and often-used items low to the ground.
• Secure or remove artwork that could potentially fall and injure a child, like a sculpture or large painting.
• Secure appliances such as refrigerators, ovens and microwaves, from tipping over.
• If you have a mounted television, make sure it’s in a place that’s out or reach for a young child.
• Put up safety gates to keep young children from rooms that have may have greater risks.

“Telling a child not to touch or climb on something is not enough, said Dr. Rosenau.  “You must take the first steps to prevent tragedy from happening in your home – by childproofing each room they are in.”

Given all the concerns about drinking sugary beverages, let’s take a look at who is consuming diet drinks across the U. S.

The following information, posted by the Centers for Disease Control , comes from the National Health and Nutrition Examination Survey, 2009-2010 describes the consumption of diet beverages among the U.S. population during 2009-2010 by sex, age, race and ethnicity, and income, and details trends in diet drink consumption from 1999-2000 through 2009-2010.

About 20% of the U.S. population aged 2 years and over consumed diet drinks on a given day during 2009-2010. The percentage consuming diet drinks was similar for females and males at all ages except among adolescents aged 12-19. The percentage consuming diet drinks increased with age for both males and females. On a given day, about 3% consumed some but no more than 8 fluid ounces (fl oz) of diet drinks, and 11% consumed 16 fluid ounces or more.

Although 15.3% of non-Hispanic white children and adolescents consumed diet drinks, only 6.8% of non-Hispanic black and 7.5% of Hispanic children and adolescents consumed any diet drink on a given day during 2009-2010. Similarly, 27.9% of non-Hispanic white adults consumed any diet drink on a given day compared with 10.1% of non-Hispanic black and 14.1% of Hispanic adults.

The percentage of higher-income persons who consumed diet drinks on a given day was greater than that of lower-income persons. A total of 18.3% of children and adolescents living in households with income at or above 350% of the poverty line consumed diet drinks, compared with 11.5% of those living between 130% and 350% of the poverty line, and 8.0% of those living below 130% of the poverty line. A similar pattern was observed for adults: Although 32.6% of adults living at or above 350% of the poverty line consumed diet drinks, only 20.1% of those living between 130% and 350% of the poverty line, and 12.2% of those living below 130% of the poverty line, consumed diet drinks.

Summary:

Overall, the percentage consuming diet drinks was higher among females compared with males. Diet drink consumption differed by age, race and ethnicity, and income. For example, the percentage of non-Hispanic white children and adults who consumed diet drinks was higher than those for non-Hispanic black and Hispanic children and adults, and the percentage of higher-income persons who consumed diet drinks was higher than that for lower-income persons.

The percentage of females and males who consumed diet drinks increased between 1999 and 2010 and was mirrored by a decrease in consumption of added sugar calories in regular soda over a similar time period. These results suggest that sugar drinks may have been replaced with diet drinks during that time.

Although substituting sugar drinks with diet drinks may promote weight loss in the short term it is unclear if long-term consumption leads to weight loss, weight maintenance, or even weight gain.
