Complete Indicator Profile of Obesity - Adolescents (Grades 9-12) (HA2020 Leading Health Indicator: 5Aii)
DefinitionObesity is determined by calculating the individual's body mass index (BMI) and comparing it to age and sex standardized growth charts distributed by the Centers for Disease Control and Prevention. Adolescents are considered obese if their BMI is greater than the 95th percentile for BMI.
NumeratorNumber of students in grades 9-12 with a body mass index (BMI) at or above the sex- and age-specific 95th percentile based on the CDC Growth Charts.
DenominatorNumber of students in grades 9-12 with complete and valid measurements for height and weight.
Why Is This Important?Overweight and obesity affect a large proportion of the Alaska population and there has been an increase in the number of obese persons over the last decade. Many diseases and adverse health outcomes are associated with overweight and obesity, including high blood pressure, type 2 diabetes, coronary heart disease, stroke, gallbladder disease, osteoarthritis, sleep apnea, respiratory problems, and some types of cancer. In addition to genetic factors, an unhealthy diet and a lack of physical activity are both key contributors to rising obesity rates. It has been projected that, due to obesity, today's children may be the first generation to have a shorter life expectancy than their parents.
Healthy People Objective NWS-10.3:Reduce the proportion of children and adolescents who are considered obese: Adolescents aged 12 to 19 years
U.S. Target: 16.1 percent
State Target: Healthy Alaskans 2020 Target: 10.0%
Other ObjectivesThe Healthy Alaskans 2010 objective of 5% for both genders was not met.
What Is Being Done?In collaboration with partners statewide, the Obesity Prevention and Control Program (the Program) provides professional development opportunities and technical assistance to school teachers and staff on evidence-based obesity prevention strategies appropriate for the school environment.
The program supports quality school-based physical education. With the Department of Education, the program recently helped develop Alaska Physical Education Standards which were adopted by the State Board of Education in July 2010. The program co-hosts the "Moving into Action: Combating Childhood Obesity" training for school nurse, health and PE teachers. The program co-hosted the PE Standards and Assessment training for PE teachers. Program staff encourages active transportation by helping coordinate Bike to Work Day and by fulfilling committee positions on the Anchorage.
The program facilitates a food policy council. The goal of the food policy council is to increase fruit and vegetable access, availability and consumption of fruits and vegetables.
The program also provides important surveillance data and publishes reports on the behaviors and risk factors that contribute to obesity to help community coalitions and partners identify and track health problems, and evaluate the effectiveness of obesity prevention efforts.

Data NotesHealthy Alaskans 2020 Target: 10.0%
** Data not available. Traditional high schools are public high schools that are distinct from correspondence schools, alternative high schools, which serve students at risk of not graduating, and students enrolled in high school in correctional facilities. Healthy Alaskans 2020 goals were established using results from traditional high school students.
