Codes and Frequencies
For sample adults, SODAMO reports the frequency with which the respondent consumed soda or other carbonated soft drinks. Other survey years report food frequency in a standardized format, recording the number of times a food was consumed and the corresponding time units. Food frequencies in 2005 are instead classified into pre-defined frequency categories. Researchers interested in using all years of available data may consider modifying SODAPNO and SODAPTP to correspond to the pre-defined categories used in SODAMO.
SODAMO is part of a series of variables initiated in 1987 related to food, food knowledge, and cancer. For related variables, please use the IPUMS NHIS search function and drop-down menus.
Data users wishing to combine SODAMO with SODAPNO and SODAPTP should be aware that prior to 2005 SODAPNO included all regular (non-diet) soda and soft drinks, including sweetened Kool-Aid and other non-carbonated, sugared soft drinks. Beginning in 2005, soft drinks were further divided and SODAPNO only includes soda and other non-diet, carbonated soft drinks.
Changes in survey design (e.g., quarters in which the supplement was collected) may affect raw frequencies, but do not affect comparability of the variable. As always, data users should use the prescribed IHIS weights.
