Obesity has been
on the rise for both adults and children in the United States.
Researchers from the Harvard School of Public Health (HSPH) believes
that the currents statistics are too low and the more people are obese
than previously thought. The reason these researchers believe that the
data is incorrect is because of the telephone surveys used to collect
the information. Telephone survey data showed that people may have
underestimated their weight and height. The report will be printed in
the May issue of the Journal of the Royal Society of Medicine.
The data collected
for the national and state level of obesity comes from two different
sources. The first source is from the Behavioral Risk Factor
Surveillance System (BRFSS) and the other is the National Health and
Nutrition Examination Survey (NHANES).
The BRFSS uses
telephone surveys to collect data and is used in both the state and
national levels for obtaining obesity statistics. The other source,
NHANES, used in-person interviews that measure the height and weight of
those who participated in a clinical exam.
