Results from the 2015-2016 National Health and Nutrition Examination Survey (NHANES), using measured heights and weights, indicate that an estimated 39.8% of U.S. adults aged 20 and over have obesity, including 7.6% with severe obesity, and another 31.8% are overweight. Body mass index (BMI), expressed as weight in kilograms divided by height in meters squared (kg/m ²), is commonly used to classify overweight (BMI 25.0-29.9), obesity (BMI at or above 30.0), and severe obesity (BMI at or above 40.0).

Age-adjusted trends in overweight, obesity, and severe obesity prevalence from 1960-1962 through 2015-2016 are shown in Table 1. Because surveys before 1988 did not include persons over age 74, Table 1 shows the prevalence for adults aged 20 and over since 1988, and for adults aged 20-74 for all survey periods dating to 1960. The age-adjusted sex-specific trends of overweight, obesity, and severe obesity among adults aged 20-74 from 1960-1962 through 2015-2016 are shown in the Figure. Table 2 contains the prevalence of obesity by age for men and women since 1988-1994, and Table 3 contains the age-adjusted prevalence of obesity by race and Hispanic origin for men and women since 1988-1994.

The prevalence of obesity as measured by BMI among non-Hispanic Asian adults was much lower than that reported for non-Hispanic white, non-Hispanic black, and Hispanic adults. Although BMI is widely used as a measure of body fat, at a given BMI level, body fat may vary by sex, age, and race and Hispanic origin. In particular, research suggests that Asian persons may have more body fat than white persons, especially at lower BMIs, and that health risks may begin at a lower BMI among Asian persons compared with others.

NHANES, conducted by the National Center for Health Statistics, is a stratified, multistage probability sample of the civilian noninstitutionalized population of the United States. The survey began oversampling non-Hispanic Asian persons for 2011-2012 and the total Hispanic population as of 2007-2008. Beginning with 2007-2008, Mexican-American persons are no longer oversampled but are included in the oversampled total Hispanic population.

A household interview and a physical examination are conducted for each survey participant. During the physical examination, conducted in a mobile examination center, height and weight are measured as part of a comprehensive set of body measurements. These measurements are taken by trained health technicians, using standardized measuring procedures and equipment. Observations for pregnant women and for persons missing a valid height or weight measurement are not included in the data analysis.

NOTES: Data are age adjusted by the direct method to the year U.S. Census 2000 estimates using age groups 20-39, 40-59, and 60-74. Overweight is body mass index (BMI) of 25.0-29.9 kg/m ²; obesity is BMI at or above 30.0 kg/m ²; and severe obesity is BMI at or above 40.0 kg/m ². Pregnant women are excluded from the analysis.

¹Age adjusted by the direct method to U.S. Census 2000 estimates using age groups 20-39, 40-59, and 60 and over. Crude estimates (not age adjusted) for 2015-2016 are 31.8% for overweight, 39.8% for obesity, and 7.6% for severe obesity categories. Age adjusted by the direct method to U.S. Census 2000 estimates using age groups 20-39, 40-59, and 60-74. The 1960-1962 National Health Examination Survey (NHANES) included adults aged 18-79, and the 1971-1974 and 1976-1980 NHANES did not include persons over age 74.
NOTES: Overweight is body mass index (BMI) of 25.0-29.9 kg/m2; obesity is BMI at or above 30.0 kg/m2; and severe obesity is BMI at or above 40.0 kg/m2. Pregnant women are excluded from the analysis.

Nearly one in five young people between the ages of two and 19 has obesity. Many youth are also technology savvy.
Rational: The use of technology to communicate the importance
of maintaining a healthy weight can be an effective give way of educate youth. (CDC, 2019)

Rational: The date identifies which populations have the highest need for intervention.
Roughly 43% of Americans were identified as being obese in 2018. An increase from 30% of obese Americans in the year 2000. The impact of obesity include the development of heart disease, stroke, and diabetes, gull bladder disease, hypertension.  Prevention of obesity is associated with overall healthier outcomes and decreased risk of premature death . minorities faced the highest health risks associted with obesity.

There is little data available to either support or contradict how the use of current data systems effect patient outcomes regarding the obese populations. Currently, methods are being formulated with the intent of providing a framework in information systems to track results of obesity interventions.

2. Rational: Findings from this survey will be used to determine the prevalence of major diseases and risk factors for diseases. Information will be used to assess nutritional status and its association with health promotion and disease prevention.

Data from this survey will be used in epidemiological studies and health sciences research, which help develop sound public health policy, direct and design health programs and services, and expand the health knowledge for the Nation.
