Description

For sample adults who, without using special equipment, have at least a little difficulty with one or more functional activity (FLANY), and for whom a first problem, not listed on the interviewer-provided flashcard and not one of the other categories available to interviewers for purposes of classifying conditions, was reported as a condition causing any activity limitation (FLNEC1), FLNEC1C reports whether the condition status was chronic. A "not elsewhere classified condition" was coded as chronic by the National Center for Health Statistics (NCHS) if it had lasted at least 3 months.

Definition of chronic condition
For the most part, conditions that have lasted 3 months or longer (or were diagnosed at least 3 months prior to the interview) are classified as "chronic" in the National Health Interview Survey. Those conditions that have lasted less than three months are generally considered "not chronic" (or acute). However, some conditions are considered "chronic" by definition, regardless of the length of time since diagnosis.
