Overweight
Is overweight changing over time?
Although overweight in the state WIC Program is above the Healthy
People 2010 objective target of 5 percent for the 2001 reporting year,
it is also important to consider if the prevalence has increased or
decreased over time. The PedNSS Table 12C, Summary of Trends in Growth and
Anemia Indicators, provides trend data in overweight prevalence for all
years that the contributor has participated in PedNSS. This table can be
used to look at recent changes in prevalence of overweight by comparing
the prevalence in 2001 with the previous year and it can be used to look
at changes that have occurred over longer periods. This trend table
includes data for all years available from the state WIC program.
Sample: PedNSS Table 12C, Summary of Trends in Growth and Anemia
Indicators

The prevalence of overweight increased slightly from
2000 to 2001, 12.5% and 12.9%, respectively. |
|
The prevalence of overweight during the 10-year period
from 1992 to 2001 increased from 8.9% to 12.9%. The absolute
increase is 4.0 percentage points and the relative increase
is 45% ((12.9 minus 8.9)/8.9 = .45 X 100 = 45 percent) during
this 10-year period. |
The following graph, derived from Table 12C, shows the gradual increase of
overweight among children 2 to 5 years of age. The line represents the Total or overall prevalence for the state WIC
program that increased from 8.9% in 1992 to 12.0% in 2001 for the trend period.

Is overweight changing over time?
Trend data show that the prevalence of overweight for children 2 to 5
years of age has increased from 8.9 to 12.9 percent, a relative increase
of 45%, therefore 45% more children were overweight in 2001 compared to
1992.
