Description

For sample adults, POPCNMNO reports how many times the respondent ate popcorn in a specified time period. POPCNMNO should be used in conjunction with POPCNMTP, which reports the corresponding time units (day, week, month, or year) stated by the respondent.

POPCNMNO is part of a series of variables related to food, food knowledge, and cancer.

Comparability

A similar variable, CHIPNO, is also available. Prior to 2000, this variable reports how many times the respondent ate salty snacks like chips, popcorn, or pretzels in a specified time period. The survey question from 2000 only asks about regular fat potato chips, tortilla chips, or corn chips. Otherwise, there are no comparability issues.
