IPAQ ITEMS - PHYSICAL ACTIVITY

MODULE INFORMATION

PURPOSE OF THE MODULE:

To assess physical activity across a comprehensive set of domains including leisure time, domestic and gardening activities, work-related and transport-related activity. The questionnaire items provide separate scores on walking, moderate-intensity, and vigorous-intensity activity as well as a combined total score to describe overall level of activity.

MODULE HISTORY:

Added to RRFSS: January 2003, Wave25

November 2005, (Wave 59) the scoring protocol for the International Physical Activity Questionnaire (IPAQ) was revised. The physical activity indicator was changed from four described physical activity levels (high, moderate, low and inactive) to three described levels (high, moderate and low).

Derived variable is available in the dataset beginning in 2007. Documentation can be found in Appendix B of the ISR annual Technical Document.

VARIABLE HISTORY:

Added: January 2003, Wave 25

MODULE QUESTION:

Now think about the physical activities you did at work, as part of your house and yard work, to get from place to place, and in your spare time for recreation, exercise or sport in the last seven days.

First, think about all the vigorous activities which take hard physical effort that you did in the last 7 days. Vigorous activities make you breathe much harder than normal and may include heavy lifting, digging, aerobics, or fast bicycling.

Think about only those physical activities that you did for at least 10 minutes at a time. During the last 7 days, on how many days did you do vigorous physical activities?

Interviewer instruction: If needed: Think about only those physical activities that you do for at least 10 minutes at a time. Include all jobs.

VALIDITY/RELIABILITY TESTS :

This question is taken from the International Physical Activity Questionnaire (IPAQ): Short Last 7 Days Telephone Format. The results of a reliability and validity study carried out in 2000/2001 indicate that this questionnaire can be used with confidence in developed countries and in urban areas of developing countries for physical activity surveillance.

MODULE INDICATORSPhysical Activity Level

INDICATOR DESCRIPTION: % of adults (18 - 69) whose level of physical activity is high, moderate, or low.

INDICATOR OBJECTIVES:To help meet the Ontario Public Health Standards (OPHS) 2008, Chronic Disease Prevention:

Requirement # 1 – Assessment and SurveillanceTo conduct epidemiological analysis of surveillance data, including monitoring of trends over time, emerging trends, and priority populations in the area of

physical activityRequirement # 11 – Health Promotion and Policy DevelopmentTo increase public awareness in physical activity

ANALYSIS CHECK LIST:The questions used were taken from the International Physical Activity Questionnaire (IPAQ): Short Last 7 Days Telephone Format that was designed primarily for population surveillance of adults. It has been developed and tested for use in adults (age range of 15-69 years) and until further development and testing is undertaken the use of IPAQ with older and younger age groups is not recommended. The RRFSS indicator uses adults age 18-69, with those aged 18-64 commonly identified as the age range of young and middle aged adults and 65+ identified as seniors. Data cleaning and processing rules are described in the document, ‘Guidelines for Data Processing and Analysis of the International Physical Activity Questionnaire (IPAQ) - Short Form and Long Forms, November 2005’, available at http://www.ipaq.ki.se/scoring.htm (scoring protocol, short form, link to pdf at bottom of page). METHOD OF CALCULATION: The physical activity levels and associated risk indicator were originally developed by Ottawa Public Health in consultation with Cora Craig at the CFLRI. They were subsequently revised in 2006 by Middlesex – London Health Unit. They are used in the CFLRI Physical Activity Monitor. The table below summarizes the criteria used for each activity level. The criteria are based on a combination of frequency (days per week) and duration (minutes per day) of walking, moderate-intensity and vigorous-intensity activity and a measure of volume of activity defined in MET-minutes per week. Work intensity is frequently described by exercise physiologists in multiples of resting metabolic rate. This index (MET) is calculated as a ratio of work metabolic rate/rest metabolic rate. MET-minutes per week are calculated by multiplying the number of days per week by the number of minutes per day by a MET value (walking=3.3, moderate=4.0, vigorous=8.0). Total MET-minutes per week is the sum of the MET-minutes per week for each intensity level of physical activity. A more detailed description is included in the document, ‘Guidelines for Data Processing and Analysis of the International Physical Activity Questionnaire (IPAQ) - Short and Long Forms November 2005’, available at http://www.ipaq.ki.se/scoring.htm (scoring protocol, short form, link to pdf at bottom of page). This document makes suggestions for categorical indicators but they are not the same as those developed for RRFSS. Respondents with don’t know, refused or missing data for any of the duration or frequency variables cannot be assigned an activity level and are excluded from the analysis. A syntax file to derive the activity levels is available on the ISR Server: PhysicalActivity_July 2005.sps.

Could not calculate level of physical activity because of missing age or age 70+, dk / refused to answer, or answer considered an outlier

To calculate the percent of respondents in each activity level:

# adults (18-69) with high (pa_level_isr=1), moderate (pa_level_isr=2) or low (pa_level_isr=3) physical activity level

# adults (18-69) assigned a physical activity level (pa_level_isr =1,2 or 3)




Excerpt from the 2010 Technical Document produced by ISR:

Physical Activity Level – November 2005 IPAQ Method – Grouped, 3 levels

Variable Name: pa_level_ISR

Based on: ipq1a, ipq1b, ipq1c, ipq2a, ipq2b, ipq2c, ipq3a, ipq3b, and ipq3c.

Description: This variable groups a respondent’s daily level of physical activity into three groups: High, Moderate, and Low. Daily amount of vigorous physical activity (MinuteVB), daily amount of moderate physical activity (MinuteMB), and daily amount of low physical activity (MinuteWB) such as walking are calculated and truncation rules are applied according to IPAQ Guidelines. Please note, a case is flagged (variable DK) if a respondent does not answer all of the required questions for the calculations. It should also be noted that the variable pa_level_ISR is the combined result of the daily amount of vigorous physical activity (MinuteVB), daily amount of moderate physical activity (MinuteMB), and daily amount of low physical activity (MinuteWB).

The analysis is summarized as follows:

1. Identifying non-responders

2. Recoding Vigorous, Moderate and Walking times to average minutes per day

3. Exclude Maximal Outliers (>960 total minutes per day)

4. Truncate remaining Vigorous, Moderate and Walking minutes to a maximum of 180 respectively

5. Calculating MET minutes (MET=Metabolic Equivalent Task, needed to derive the levels of physical activity)

6. Derive levels of physical activity (final variable = "pa_level_ISR"). The pa_level_ISR is not calculated if a respondent was not asked this module (i.e., none of the questions are asked or not all questions in the module are answered)
