Overweight and Obesity in the LSAH Population (LSAHNEWSV13_1_2)
Research Area:
Metabolism and nutrition
Species Studied
Scientific Name: Homo sapiens Species: Human

Description
OBJECTIVES:
The rising prevalence of overweight and obese Americans has been the frequent topic of recent media articles. Various national surveys show that the majority of Americans are overweight. According to data obtained from the National Health and Nutrition Examination Survey (NHANES), the percentage of overweight adults (ages 20-74) in the general population has increased from 45% in 1960-1962, to 64% in 1999-2000. The percentage of obese individuals has increased from 13% to 31% within the same time period. The terms overweight and obesity are defined using the Body Mass Index (BMI), a measure that expresses the relationship of weight to height. BMI is calculated by dividing weight in kilograms by the squared height in meters. This study compared the BMI of the Longitudinal Study of Astronaut Health (LSAH) participants with that of the general population.
