Complete Indicator Profile of Overweight - Adults (18+) (HA2020 Leading Health Indicator: 4A)
DefinitionPercentage of adults aged 18 years and older with a body mass index of >= 25.0 and <30.0. (BMI calculated as self-reported weight in kilograms divided by self-reported height in meters squared.)
NumeratorNumber of adults aged 18 years and older who have a body mass index (BMI) body mass index of >= 25.0 and <30.0 calculated from self-reported weight and height. Excludes women who are pregnant and biological implausible values.
DenominatorNumber of adults aged 18 years and older for whom BMI can be calculated from their self-reported weight and height. Excludes women who are pregnant, biological implausible values, unknowns or refusals for weight and/or height).
Why Is This Important?About one-third of Alaskan and American adult population is overweight. Overweight and obesity and their associated health problems have a significant economic impact on the U.S. health care system. Overweight and obesity are determined by calculating Body Mass Index (BMI) from a person's weight and height. BMI provides a reliable indicator of body fatness for most people and it is used to screen for weight categories that increase the risk of health problems.
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.

Other ObjectivesThe Healthy Alaskans 2010 target for adult overweight prevalence of 30% or lower was not met.
Healthy Alaskans 2020 Target: 36.0%
How Are We Doing?The percentage of adult Alaskans who are overweight has increased over the past 2 decades, from 35% 1991 to 38% in 2010.
The Healthy Alaskans 2010 target for adult overweight prevalence was 30% or lower. The prevalence of adult overweight in Alaska remained relatively stable during the Healthy Alaskans 2010 monitoring period, from a baseline of 41% in 1999 to a level of 38% in 2010. The Healthy Alaskans 2010 target of 30% was not met.
There are no significant differences in overweight by race, region, or socioeconomic status. (Source: 2009 BRFSS) Additional statistics on overweight in Alaska are available at: http://www.hss.state.ak.us/dph/chronic/obesity/resources.htm.
How Do We Compare With U.S.?The rate of overweight among adult Alaskans has paralleled the rate seen in the US overall.
What Is Being Done?In collaboration with partners statewide, the Obesity Prevention and Control Program provides professional development opportunities and technical assistance to health professionals, partner agencies, individuals, schools and the media on evidence-based overweight and obesity prevention strategies. The program also provides important monitoring data and publishes reports on the behaviors and risk factors that contribute to overweight and obesity to help community coalitions and partners identify and track health problems, and evaluate the effectiveness of overweight and obesity prevention efforts.

** Data Not Available
Alaska data were obtained from the Standard AK BRFSS from 1991-2003, and from the Standard and Supplemental AK BRFSS surveys combined from 2004 onward. The Supplemental BRFSS survey is conducted using identical methodology as the Standard BRFSS and allows a doubling of the BRFSS sample size for those measures included in both surveys.
Post-stratification weights were used for Alaska prior to 2006; raking weights were used from 2007 onward. For more on this methodological change see: http://dhss.alaska.gov/dph/Chronic/Pages/brfss/method.aspx.
