Year of most recent breast exam


BXLDYR is a 4-digit-numeric variable.

9998: Unknown-not ascertained
9999: Unknown-don't know


For sample adult women who have had a breast physical exam (BXEV), BXLDYR reports the year of the most recent breast physical exam. BXLDMO reports the month of the most recent breast physical exam. There two variables should be used together.

For women who did not know the year, interviewers probed to find out if it was less than a year ago, or more than one, two, three, or five years ago. Responses included the calendar year or the interval of years since the last exam. For 1987 and 1992, several follow-up questions on the reason for the exam (and results of the exam for 1987) were limited to women who had an exam in the past three years.
