Obesity Linked to Lack of Sleep in Childhood

Enforcing bedtime rules may be an important factor in helping kids maintain healthy weight levels. A comprehensive research review of 42 studies with 75,499 participants, conducted by University of Warwick researchers in Coventry, England, found that short sleep durations in infants, children and adolescents were a risk factor for gaining weight and developing obesity. Data analysis showed that children and teens who slept less than others of the same age gained more weight as they grew older and were more likely to become overweight or obese.

Young Talent in the Kitchen

If we want adults to eat a healthier diet, we should get them cooking more often when they’re young. That’s the conclusion of a report published in the May edition of the Journal of Nutrition Education and Behavior. The findings drew on data from the Project Eating and Activity in Teens and Young Adults longitudinal study in the Minneapolis-Saint Paul area.

To Grow Healthier, Happier Adults, Raise Fit Kids

Today’s inactive kids are tomorrow’s unhealthy adults. Our society will pay the price for young people’s profound lack of exercise if we fail to turn this trend around. Few behaviors more significantly influence child health than physical activity. Yet children and adolescents are not moving enough, at the expense of their own health as well as that of their communities. More needs to be done to support families and society in raising fit kids.

What Type of Exercise You Do as a Kid May Determine Your Weight as an Adult

According to new research, the kind of physical activity you do in childhood could predict whether you will be overweight as an adult.
Published in Medicine & Science in Sports & Exercise (2018; 50 [4],
709–14), the study examined the relationship between adult weight gain and the following types of exercise in childhood: running, sports and/or fitness/dance.

A for Effort

A complete course load. Think of it as core curriculum—literally. The Kent Denver School, a college-preparatory institution outside of Denver, offers a comprehensive educational experience that emphasizes both academics and sports. That’s where Laura Bordeaux comes in.

Teen Fitness Matters

Keep encouraging teens to get active. Vigorous exercise is particularly beneficial for lowering their risks of heart disease later in life, according to recent research. Current public health guidelines recommend that children aged 5–18 should do at least 60 minutes of moderate to vigorous physical activity daily to reduce current and future heart disease risks.

Best Foot Forward

A challenging beginning. Ezra didn’t have an easy start. Born with club feet—a congenital condition in which the foot is twisted out of shape or position—he had his first surgery shortly after birth and spent the first few years of life sleeping with corrective boots.

Fitter Kids Have More Brain Gray Matter

While much research has pointed to a relationship between kids’ fitness and academic performance, we now have a new piece of the puzzle: A recent study found that aerobic fitness and speed–agility levels among overweight and obese children aged 8–11 were independently associated with more gray matter in parts of the brain related to better academic performance.

Range of Motion: Full or Partial?

Research shows there’s a time and place for both full and partial range of motion in resistance training program design.
Some training systems purposely use partial ROM for various exercises. Moreover, certain surgeries and orthopedic injuries require partial-ROM movements during rehabilitation (Pinto et al. 2012). It seems natural for personal trainers to wonder which is superior: full ROM or partial ROM? ,/p>
Two studies comparing the benefits of partial ROM and full ROM give a clearer view of the landscape.

There Is Arsenic in Your Rice

For generations, pediatricians have recommended rice cereal as a first food for babies in the transition to eating solids. Rice cereal is easy for babies to eat and is high in iron, an important nutrient for growing brains. However, recent research cited in Consumer Reports found persistently high levels of arsenic in rice and rice products, including infant rice cereal.
Rice tends to absorb more arsenic than other grains mostly because it is grown in water-flooded soil.

Sugary Drinks in Pregnancy Linked to Increased Asthma Risk in Babies

The thirst for sugary drinks remains strong in all U.S. populations despite multiple health risks. However, moms-to-be have a new reason to decrease (or better, eliminate) sugary drinks during their pregnancies. A new study in Annals of the American Thoracic Society suggests that limiting intake of sweetened beverages may lower babies’ asthma risk in childhood (in addition to reducing the risk of obesity).

Kids Who Eat Fish Have Higher IQ, Sleep Better

A Scientific Reports study of Chinese school­children found that those who said they ate fish at least twice a week when aged 9–11 slept better and longer and had IQs nearly 5 points higher when they were 12 than children who ate no fish. The authors suggested the higher IQs could be mediated through better-quality sleep. This study adds to a body of science demonstrating strong relationships between fish intake, health and quality of life for kids and adults alike.

Resistance Training for Youth: 10 Tips for Success

Resistance training for youth can be a polarizing topic, mostly because of misconceptions about safety, injury rates and training techniques. Though parents and trainers alike often worry about the hazards of youth resistance training, research shows that it has a host of benefits—if it’s done properly.

Millennials Prefer “Activacations”

According to a recent survey produced by Hotels.com, most millennials prefer to lift weights instead of piña coladas while on vacation. Savvy fitness professionals can leverage this
information when marketing and promoting programs to this demographic.

Weight Disparities in Children Worldwide

When it comes to childhood health, lots of emphasis is placed on the risks of being overweight or obese—and an estimated 124 million kids worldwide were in those weight categories in 2016, a tenfold increase since 1975. While this is of great concern, a new study has found that in the same year, 192 million boys and girls were moderately or severely underweight. The researchers believe that family income levels may play a role in a child’s weight.

New Way to Calculate Childhood Obesity

Over the years, experts have questioned the accuracy of body mass index scores, known as BMI “z-scores,” for estimating body fat percentages in kids (the z is specific to younger age groups and requires complicated calculations to get results). The criticism is that adolescent weight doesn’t scale with height, which can produce faulty data. Now, researchers claim to have discovered a new, more accurate formula for measuring body fat in kids aged 8–17.

Lifetime Physical Activity Trends

What does a 19-year-old have in common with a 60-year-old? Both achieve about the same amount of weekly activity, according to new research.
This information comes from a study of 12,529 individuals aged 6–85 who participated in the National Health and Nutrition Examination Survey. The researchers’ primary goal was to analyze lifetime physical activity (PA) changes via accelerometer data—and their conclusions are disheartening. Here are some key points from the report:

New Dangers Associated With Childhood Obesity

Having obesity as a kid doesn’t just create immediate risks. According to a new study, it may also set the stage for significant health problems later on.
While being obese in childhood is known to predict adulthood obesity, the study’s purpose was to learn about other potential and undetermined weight-related health risks that might take root in the early years. Specifically, the researchers focused on how childhood obesity related to cardiovascular disease and abnormal blood sugar levels that result in disease.

Exercise Mitigates Stress-Related Weight Gain in Kids

School work, social situations, family challenges—young kids are faced with a great deal of pressure and perhaps lack the proper outlets to handle it. And as previous research has shown, stress and weight gain sometimes go hand in hand. A new study published in Medicine & Science in Sports & Exercise (2017; 49 [3], 581–87) shows that exercise may help kids manage stress and prevent weight gain.
