How Common It Is - Prevalence, Trends, and Disparities
Childhood Obesity
- In 2016, about 12 percent of children (ages 2-4 years old and receiving WIC services) were obese.
- In 2016, about 12 percent of 10th graders in Washington's public schools were obese.
- Rates for 10th grade obesity rose significantly from 10 percent in 2014 to 12 percent in 2016 after several years of remaining the same. This recent uptick changes the trend from level to rising slowly since 2006.
- Among 10th graders, American Indian/Alaska Native, black, Hispanic and Native Hawaiian/Pacific Islander populations continue to be at increased risk of overweight and obesity than whites or Asians (Table 1).

Adult Obesity
- In 2016, about 29 percent of Washington adults were obese.
- Adult obesity trends have started to level off over the past few years, however between 2014 and 2016 there was a significant increase from 26 percent to 29 percent.
- Obesity rates were higher in populations with lower income (Table 2) and lower education (Table 3). Among adults:
- American Indian/Alaska Native and Native Hawaiian/Pacific Islander populations had the highest age adjusted rates of obesity.
- Black and Hispanic adults had a higher rate of obesity than non-Hispanic whites and Asians (Table 4).
- In the 2014-2016 BRFSS, males had a higher prevalence of obesity than females.
- Obesity prevalence was lowest among young adults 18-24 years old.

Pre-pregnancy Obesity and Weight Gain during Pregnancy
- Pre-pregnancy obesity and weight gain above the recommended range during pregnancy can increase health risks for mother and child.
- In 2015, about 25% of women were obese prior to pregnancy in 2015. Approximately 48% of all women gained more weight than recommended during pregnancy.
