Codes and Frequencies
For sample adults, MARGTP reports the time unit (day, week, month, or year) that corresponds with the frequency with which the respondent reported eating margarine. This includes margarine on bread, rolls, or vegetables. Respondents were asked separately about butter consumption. MARGTP should be used in conjunction with MARGNO, which reports the corresponding frequency stated by the respondent. For information about the portion size, see MARGSIZ.
MARGTP 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.
