Description
For persons sample persons age 12 to 21 in 1992 and sample persons age 18 and older in 1991, 1993, 1995, and 1998, WTCHANGE reports if the sample person is now trying to lose weight, gain weight, stay about the same, or not trying to do anything about his or her weight. Please refer to the universe tab for changes in the universe.
Comparability
Changes in universe affect comparability between the 1992 sample and other sample years. Changes in survey design (e.g. quarters in which the question is asked) affect raw frequencies, but do not affect comparability of the variable. As always, data users should use the prescribed IPUMS NHIS weights.
