Nutrition, Physical Activity and Obesity (Group D)


CDC Winnable Battle Goal:  Nutrition, Physical Activity and Obesity
Group members: Moube Ewane, Wenhui Liu, Molly Russell & Rachel Saylor

Why do we care?
Nutrition and physical activity play a key role in combating obesity and making the US a healthy nation.  The rate of obesity in the US is 35.7% in adults and 16.9% in kids (Ogden CL, 2012).  The number of obese and overweight individuals in the US has been steadily climbing since the 1980s, as depicted in the graph below (Guyenet, 2008).


The number of overweight and obese Americans is going to keep climbing, and by the year 2030 all fifty states are estimated to have obesity rates between 44-60% (TFAH, 2012).  Colorado is actually the least obese state in the nation – 20.7% of adults in Colorado are obese.  That may seem like we’re doing a good job, and we are compared to the national average, but think about it: for every five adults you know, one of them is obese.  By the year 2030, an estimated 44% of Coloradans will be obese.  Obesity contributes to a multitude of health problems, like heart disease, stroke and cancer (CDC, 2012), which means it’s really important to take control of your weight and your health. 
 

Check out the HBO documentary The Weight of the Nation.

What can we do?
Part of the reason people are obese is due to the fact that only 48% of American adults and less than 30% of high school students meet the requirements for daily physical activity (CDC, 2012).  The US Department of Health and Human Services is aiming to decrease the number of people who don’t participate in physical activity in their free time, and their goal is marked in this graph  (CDC, 2013). 


Exercise is a wonderful way to keep yourself healthy, and it doesn't take much - just 30 minutes of walking five days a week (CDC, 2011).  And did you know you can break up those 30 minutes into 10 minute segments?  It's springtime in Colorado - 10 minute walks a few times a day is a great way to enjoy the sunshine!  Or take your family swimming, for a bike, or try a new sport as a family.  Check out this video for inspiration!

Studies have shown that the main culprit of obesity is physical inactivity. Childhood is a very important time for the development of motor coordination skills, which are pertinent for health and general well being. Sedentary lifestyle (physical inactivity) has a negative effect of such motor skills, and is associated with decreased fitness, low self-esteem, decreased academic achievement and increased obesity. Also, the origin of sedentary lifestyle can be traced to modern technological conveniences such as video games, Internet, cell phones, television, cars, and fast food. Hence having little or no time for physical exercise

Another reason the US is combating an obesity epidemic is because of poor nutrition.  We’re eating too much, and it’s not healthy food.  In fact, it’s not just a US problem, but the whole world.  Look at this graph showing the increase in calorie consumption since the 1960s (Wikipedia, 2009).



  

Between 2005 and 2010, 13% of calories in an average adult diet came from added sugar. It was 16% for adolescents (CDC, 2013). That’s up to 400 calories every day from added sugar! The graph to the right shows the average number of calories from added sugar for men and women in different age groups.


A lot of that added sugar is probably coming from soft drinks.  We’re drinking too much soda and too little of healthy beverages, like milk.  The trends are highlighted in this graph, and it’s astonishing how much soda we drink.

Top Sources of Sodium in the Diet
  Breads and rolls
  Cold cuts and cured meats
  Pizza
  Poultry
  Soups
  Sandwiches
  Cheese
  Pasta dishes
  Meat dishes
  Snacks
Decreasing sodium in your diet will also help you maintain a healthy body weight. Take a look at this table that lists the most common foods with high amounts of sodium (CDC, 2012). Aim for 2,300 mg of sodium each day – the average American takes in ~3,600 mg of sodium!   















 
So, we’re eating too much sugar and salt – what can we eat?  Lots of ruits and vegetables!  Chances are, you’re not getting enough produce in your diet – most Americans don’t.  Remember – half of your plate a meal times should be fruits and vegetables!  Check out this tutorial or visit MyPlate.gov for ideas.


Aim for 2 cups of fruit and 2 ½ to 3 cups of veggies every day.  That may sound like a lot, but here are some great examples to get you started (CDC, 2012)!  Remember to set a good example for the children in your life, and make sure they’re getting proper nutrition, too.



Another important way to ensure proper nutrition for kids is to support breastfeeding.  If you’re not a mom, you might not think this is important, but breastfeeding has been associated with lower chances of obesity and better health outcomes, even after children stop breastfeeding.  The number of babies breastfed at 6 months has been increasing, as seen in the graph below (CDC, 2012).  But Healthy People 2020 is aiming for a 15% increase in babies breastfed at 6 months (CDC, 2013), so even if you’re not a new mom, you can support breastfeeding by providing a support system for your friends and family!



The bottom line is to exercise, eat your fruits and veggies, breastfeed if you can, and do the same for your kids!

What actions have been taken?

 How can I get involved?  What if I need ideas or support?
Despite the increasing rate of obesity, there are many national programs that have been put in place to combat childhood obesity and increase physical activity. One of these programs is NFLPlay 60 (NFL, 2013). The National Football League founded this program in collaboration with USDA. The main purpose of this program is to encourage children to be physically active for at least 60 minutes a day while also eating healthy foods. NFL players visit schools and encourage children to exercise with them.
In addition, there’s a program to fight obesity and increase physical activity among children and adolescence called NBAFit (NBA/WNBA, 2013), founded by the NBA/WNBA. This program allows players to visit schools and youth centers across the country and exercise with children, either by playing basketball, running, weight lifting, jumping ropes, etc, just like the NFL Play 60 program.
Another national program aimed to fight childhood obesity and increase physical activity is called Let’s Move (Let's Move), founded by Michelle Obama. You can get your groove on like Beyonce in this video!
At the state level, there are many actions that have been taken in Colorado to fight childhood obesity and increase physical activity and improve nutrition. For example, the LiveWell Colorado (LiveWell Colorado, 2013) is an organization that advocates for legislative actions to lower childhood obesity, such as fighting to ban or limit junk food advertisement, increase consumption of fruits and vegetables in schools, reduce sugary drinks in school vending machines, etc.
Another action that is being carried out in Colorado is called everykid healthy, sponsored by Colorado Action for Healthy Kids (Colorado Action for Healthy Kids, 2013). Colorado Action for Healthy Kids fight childhood obesity and hunger by partnering with local schools and centers to improve nutrition and increase level of physical activity among children.
Last but not the least, another initiative that has been around for a long time to combat childhood obesity is the physical education courses that had been provided to middle and high school students. According to CDC, there is a positive correlation between physical education (P.E.) classes, academic performance and obesity. A child who takes P.E. classes is less likely to be obese, and more likely to perform better in class than someone who does not (CDC, 2010).

Healthy People 2020 Goals & Objectives
Healthy People, under the U.S. Department of Health and Human Services (HHS), a science -based to make national goals and objectives to guide US health efforts. The Healthy People 2020 sets goals on nutrition and physical activity for children and an adult that is paired with objectives based on current baseline numerical data. This baseline data is used to set ten year objective benchmarks in nutrition, 21 objectives and physical activity with 15 objectives.
The programs above meet the Health People 2020 Nutrition and Weight Status goal because they try to promote health and reduce chronic disease risk through the consumption and access of healthier food and vegetables. Some of these states and national program meet the Healthy People 2020 goal of physical activity because these programs, for example the let’s move campaigned championed by the first lady, Michelle Obama, the NFL play 60, etc. tries to improve health, fitness, and quality of life especially among youths through encouragement of daily physical activity

Healthy People 2020 Goals
Nutrition and Weight Status
Promote health and reduce chronic disease risk through the consumption of healthful diets and achievement and maintenance of healthy body weights.

Physical Activity
Improve health, fitness, and quality of life through daily physical activity


The Colorado Health Foundation is monitoring the progress of some of these objectives, on a biannual basis, through the Colorado Health Report Card.  The most recent 2012 Colorado Health Report Card reflects how the state is doing on similar goals compared to other states.

The Future
We feel that the broad topic of nutrition, physical activity and obesity is a winnable battle because people want to be healthy.  We can promote healthy eating by supporting state and federal regulations to strengthen nutrition standards for foods served in schools.  We will encourage physical activity by creating physical activity standards in Colorado’s public schools.  We can’t afford not to!
