77593-2

LOINC code 77593-2 identifies "Vigorous physical activity [IPAQ]". A patient's total vigorous physical activity can be reported as a continuous variable based on the duration (e.g. in minutes) and frequency (e.g. days) of vigorous activity over the past 7 days. In the International Physical Activity Questionnaire (IPAQ) Long form, the patient is asked separate questions on vigorous physical activity in two domains: at work and in leisure time. The total duration and frequency for these domains is used to calculate the patient's vigorous physical activity level. In the IPAQ Short form, these domains are grouped together into a single question for duration and another for frequency of vigorous physical activity in the last 7 days. The activity level is reported in MET-minutes/week or MET-minutes/day, although the former is more frequently used and is thus suggested. Calculation for vigorous physical activity for the long and short IPAQ forms: Short form: Vigorous MET-minutes/week = 8.0 * vigorous-intensity activity minutes per day * vigorous-intensity days per week Long form: Vigorous MET-minutes/week = 8.0 * total vigorous-intensity activity minutes per day (at Work + in Leisure) * total vigorous-intensity days per week (at Work + in Leisure)

This code measures Vigorous physical activity in ^Patient. It belongs to the SURVEY.IPAQ class in the LOINC classification.

LOINC (Logical Observation Identifiers Names and Codes) is a universal standard for identifying laboratory and clinical observations. It is maintained by the Regenstrief Institute and used worldwide for health data exchange.
