Some definitions from the CDC: Overweight is defined as having excess body weight for a particular height from fat, muscle, bone, water, or a combination of these factors. Obesity is defined as having excess body fat.
Overweight and obesity are the result of “caloric imbalance”—too few calories expended for the amount of calories consumed—and are affected by various genetic, behavioral, and environmental factors.
We are so pleased to have so many top obesity researchers and clinicians on this chat as well as so many advocacy groups and concerned parents. This is an important topic and we at ABC Health hope you get a lot out of this chat.
Getting ready for the first topic!
Important stats from the CDC: Childhood obesity has more than doubled in children and tripled in adolescents in the past 30 years.
The percentage of children aged 6–11 years in the United States who were obese increased from 7% in 1980 to nearly 18% in 2010. Similarly, the percentage of adolescents aged 12–19 years who were obese increased from 5% to 18% over the same period.
In 2010, more than one third of children and adolescents were overweight or obese.
Some sobering stats from the CDC....
Children who are overweight or obese as preschoolers are 5 times as likely as normal-weight children to be overweight or obese as adults.
Obesity among low-income preschoolers declined, from 2008 through 2011, in 19 of the 43 states and territories studied.
About 1 in 8 preschoolers is obese in the US.

Obese youth are more likely to have risk factors for cardiovascular disease, such as high cholesterol or high blood pressure. In a population-based sample of 5- to 17-year-olds, 70% of obese youth had at least one risk factor for cardiovascular disease.
Obese adolescents are more likely to have prediabetes, a condition in which blood glucose levels indicate a high risk for development of diabetes.
Children and adolescents who are obese are at greater risk for bone and joint problems, sleep apnea, and social and psychological problems such as stigmatization and poor self-esteem.
Children and adolescents who are obese are likely to be obese as adults 11-14 and are therefore more at risk for adult health problems such as heart disease, type 2 diabetes, stroke, several types of cancer, and osteoarthritis.
One study showed that children who became obese as early as age 2 were more likely to be obese as adults.
Overweight and obesity are associated with increased risk for many types of cancer, including cancer of the breast, colon, endometrium, esophagus, kidney, pancreas, gall bladder, thyroid, ovary, cervix, and prostate, as well as multiple myeloma and Hodgkin’s lymphoma.
Read this excellent report from the Robert Wood Johnson Foundation about health school lunches. It's highlighted in the following tweet....
Schools in 19 states, from Arkansas to Illinois, participate in the annual student weigh-ins. Some pediatricians say body mass index (BMI) readings are helpful in combating childhood obesity, which is a growing problem.
Arkansas was the first state to initiate BMI Report Cards in 2003. So far this is what they've found:
1. The report cards did not note an increase in eating disorders or restricted diets
2. The state had to decrease from yearly screening to every other year screening due to financial issues
3. After 4 years of implementation (2003-2007) the percentage of those overweight (20.9) and obese (17.2) did not increase
4. Only 3% of parents refused assessment each year
Some facts about physical education:
Some facts about physical education...
For kids and teens (that’s anyone between 6 and 17 years), your goals are: active 60 minutes a day, at least 5 days a week, for 6 out of 8 weeks. As an alternative, you can count your daily activity steps using a pedometer (girls’ goal: 11,000; boys’ goal: 13,000).
• In 2011, only 29% percent of high school students had participated in at least 60 minutes per day of physical activity on each of the 7 days before the survey.
• Fourteen percent of high school students had not participated in 60 or more minutes of any kind of physical activity on any day during the 7 days before the survey.
• In 2011, over half (52%) of high school students (68% of 9th-grade students but only 38% of 12th-grade students) attended physical education classes in an average week.
• The percentage of high school students who attended physical education classes daily decreased from 42% in 1991 to 25% in 1995 and remained stable at that level until 2011 (31%).
• In 2011, 41% of 9th-grade students but only 24% of 12th-grade students attended physical education class daily.
