Health Indicator Report of Overweight - Adolescents (Grades 9-12) (HA2020 Leading Health Indicator: 5Ai)

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.^2^ 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. An unhealthy diet and a lack of physical activity are both key contributors to rising obesity rates.^3^ 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.^4^[[br]] [[br]] ---- {{class .SmallerFont 2.

Data Interpretation Issues

Although the prevalence of overweight is presented independent of obesity in this report, interpretation of the overweight results should be conducted in the context of data on obesity prevalence. Subpopulations may have relatively low rates of overweight paired with relatively high rates of obesity. It is the combination of overweight and obesity prevalence that gives the most complete picture of risk for weight related health conditions. Alaska has conducted a statewide Youth Risk Behavior Survey in 1995 and biennially from 2003. Weighted data were not obtained in 2005 and therefore no statewide estimates are available for that year. A YRBS survey conducted in 1999 did not include the Anchorage School District and therefore was not considered a valid statewide estimate. No YRBS survey was conducted in Alaska in 1997 and 2001. Traditional high schools are sometimes called comprehensive high schools. They are public high schools that are distinct from alternative high schools, which serve students at risk of not graduating, charter schools, correspondence schools, and students enrolled in high school in correctional facilities. Responses are weighted to reflect youth attending public traditional high schools in Alaska. The ability to compute BMI has been present on the YRBS since 2003.

Definition

Percentage of adolescents (students in grades 9-12) who provide height and weight on the [http://www.cdc.gov/healthyyouth/data/yrbs/index.htm Youth Risk Behavior Survey (YRBS)] with a body mass index (BMI) at or above the sex- and age-specific 85th percentile and less than the 95th percentile based on the CDC Growth Charts.^1^ Weight status is computed on the Youth Risk Behavior survey (YRBS) using two questions: "How tall are you without your shoes on?" (responses in feet and inches) and "How much do you weigh without your shoes on?" (responses in pounds).[[br]] [[br]] ---- {{class .SmallerFont 1. U.S. Centers for Disease Control and Prevention. National Center for Health Statistics. Growth Charts. [http://www.cdc.gov/growthcharts/clinical_charts.htm] }}

Numerator

Weighted number of adolescents (students in grades 9-12) responding on the YRBS with BMI at or above the sex- and age-specific 85th percentile and less than the 95th percentile based on the CDC Growth Charts.

Denominator

Weighted number of adolescents (students in grades 9-12) on the YRBS with complete and valid measurements for height, weight, age, and sex.

Other Objectives

Healthy Alaskans 2020 Leading Health Indicator 5.a.i: Reduce the percentage of adolescents (high school students in grades 9-12) who meet criteria for overweight (age- and sex-specific body mass index of >=85th and <95th percentile) to 12% by 2020.

How Are We Doing?

The rate of overweight has increased among all Alaska adolescents to 16.7% in 2015 from 14.4% in 2003 and similarly for Alaska Native adolescents to 16.9% in 2015 from 13.0% in 2003. The rates for the combined overweight and obese risk factor exhibit a similar pattern of being 30.8% in 2015 for all Alaskan adolescents compared to 25.5% in 2003, a 20% increase from 12 years earlier. The rate of overweight in Alaska adolescents in 2015 exceeds the Healthy Alaskans 2020 goal of 12%. Prevalence rates of overweight from the YRBS are initially presented all Alaska adolescents, Alaska Native adolescents, and the mean of the national YRBS. The combined risk factor of being overweight or obese is then shown. Subsequent analyses display overweight rates by demographic subpopulations (i.e., sex, age, race/ethnicity, ethnicity, grade level, and academic achievement) and regions.

How Do We Compare With the U.S.?

In 2015, the prevalence of overweight for all Alaskan adolescents of 16.7% was above but no significantly different from the national average on the YRBS of 16.0%.

What Is Being Done?

The mission of the Obesity Prevention and Control Program is to prevent and reduce obesity among Alaskans though the promotion of physical activity and good nutrition. The program: [[br]]a) manages the Play Every Day campaign, Community Nutrition efforts, Early Care and Education (ECE) Obesity Prevention Partnerships, the Obesity Prevention School Partnerships and supports Healthy Futures; [[br]]b) serves as a credible source of information on the causes, health and economic consequences of obesity; [[br]]c) provides information to the public, health professionals, and the media; [[br]]d) maintain systematic collection, analysis, evaluation and reporting of obesity prevalence and related physical activity and nutrition behaviors; [[br]]e) identifies population groups at greatest risk for the health threats of obesity; [[br]]f) develops partnerships with and provides leadership to a wide variety of private and public agencies; [[br]]g) provides technical advice and support to partners in implementing obesity prevention strategies; [[br]]h) facilitates the Alaska Alliance for Healthy Kids that works to prevent childhood obesity; and [[br]]i) facilitates the Alaska Food Policy Council that works to strengthen Alaska's food systems to spur local economic development, increase food security, and improve nutrition and health.^5^[[br]] [[br]] ---- {{class .SmallerFont 5.

Evidence-based Practices

As part of the Healthy Alaskans 2020 health improvement process, groups of Alaska subject matter experts met over a period of months in a rigorous review process to identify and prioritize strategies to address the 25 health priorities. '''Strategy 1:''' [[br]]Implement a comprehensive social marketing campaign promoting nutrition and physical activity. Choose campaign topics strategically; examples include limiting sugary drinks and the importance of family meals. '''Evidence Base:''' [[br]]Citing The Community Guide and other reviews, the CDC recommends community-wide campaigns as effective in increasing physical activity, a contributing factor to maintaining a healthy weight. '''Sources:''' [[br]]Centers for Disease Control and Prevention. Increasing physical activity: A report on recommendations of the Task Force on Community Preventive Services. MMWR. 2001; 50 (RR-18): 1-16. [http://www.thecommunityguide.org/pa/index.html The Community Guide] Kahn EB, Ramsey LT, Brownson RC, et al. The effectiveness of interventions to increase physical activity: a systematic review. Am J Prev Med. 2002; 22(4s): 73-107. '''Strategy 2:''' [[br]]Increase the number of breastfeeding-friendly maternity facilities. '''Evidence Base:''' A systematic review from the Agency for Healthcare Research and Quality (AHRQ) concluded that infants who are not breastfed are more likely than breastfed infants to experience a number of poor health outcomes, including obesity (Ip et al., 2007). A Cochrane review of studies found that one effective approach for increasing breastfeeding initiation and duration rates is through support for institutional changes in maternity care practices (Fairbank et al., 2000). Specifically, the Baby-Friendly Hospital Initiative has been demonstrated to lead to improved breastfeeding rates (Philipp et al., 2001). '''Sources:''' Ip S, Chung M, Raman G, et al.

Baby-friendly hospital initiative improves breastfeeding initiation rates in a US hospital setting. Pediatrics. 2001; 108(3):677-681. '''Strategy 3:''' Adopt and implement new school physical activity and nutrition policies, also known as "wellness policies". '''Evidence Base:''' Many of the evidence-based strategies to address childhood obesity (such as promoting quality PE and health education, and establishing a Safe Routes to School program) depend on the support of schools, communities, and parents to implement. Therefore a strategy recommended by the CDC, US DHHS and the IOM is to support the adoption and implementation of school physical activity and nutrition policies (also known as "wellness policies") by school districts.
