Introduction
The Canadian Health Measures Survey (CHMS) is the most extensive national survey on physical health measures ever conducted in the country. Data collection consists of two steps, a personal interview at the respondent’s household followed later by a visit to the CHMS mobile clinic where physical measurements and blood and urine samples are taken.
The CHMS captures a broad portrait of the health of Canadians by gathering baseline data on a variety of concerns, including cardiovascular health, nutritional status, chronic diseases and physical activity, as well as exposure to infectious diseases and environmental contaminants. The survey collects health information that can’t be otherwise captured, or that may be inaccurately reported, through self-report questionnaires or health care records.
The CHMS is conducted by Statistics Canada in partnership with Health Canada and the Public Health Agency of Canada.
During CHMS cycle 1, physical measurements were collected in 15 sites across Canada from about 5,600 people representing the Canadian population aged 6 to 79. Collection sites were located in five provinces: New Brunswick, Quebec, Ontario, Alberta and British Columbia. Collection started in March 2007 and continued until February 2009. Data are representative at the national level.
This publication is part of the release of CHMS data beginning in January 2010. It provides information on the composition of the derived variables created both during and after data processing for the Wave 4 release. Additional volumes will be provided for future releases.

Activity Monitor – Master File (98 DVs)
1. AMMDACT1 – Average counts – Day 1 (counts per minute)
Variable name:
AMMDACT1
Description:
Average counts per minute were calculated by dividing the sum of counts for a valid day by the number of minutes of wear time in that day across all valid days. Average counts per day evaluate the raw data provided by the accelerometer without imposition of external criteria (e.g., cut-points) other than determination of wear and nonwear time.
Note:
The SAS code used to derive this variable is available on request.
2. AMMDACT2 – Average counts – Day 2 (counts per minute)
Variable name:
AMMDACT2
Description:
Average counts per minute were calculated by dividing the sum of counts for a valid day by the number of minutes of wear time in that day across all valid days. Average counts per day evaluate the raw data provided by the accelerometer without imposition of external criteria (e.g., cut-points) other than determination of wear and nonwear time.

8. AMMDBMV1 – Total number of bouts of moderate-to-vigorous physical activity – Day 1
Variable name:
AMMDBMV1
Description:
Time spent in bouts of moderate-to-vigorous physical activity is derived using an intensity cut-point and is theoretically equivalent to > 3 METs (i.e., counts both moderate and vigorous physical activity together). The metabolic equivalent (MET) is a value of metabolic energy cost expressed as a multiple of the resting metabolic rate. For example, an activity of 4 METs requires four times the amount of energy as compared to when the body is at rest. The number of bouts of moderate-to-vigorous physical activity were counted for each valid day.
For children, moderate-to-vigorous physical activity was counted as a bout if a minimum of 4 out of 5 consecutive minutes were above the moderate-to-vigorous cut-point. For adults, moderate-to-vigorous physical activity was counted as a bout if a minimum of 8 out of 10 consecutive minutes were above the moderate-to-vigorous cut-point.
The moderate cut-point used for children (1,500 cpm) was obtained from a calibration study that related Actical counts to measured energy expenditure (Puyau, Adolph et al., 2004). The moderate intensity cut-point used for adults (1,535 cpm) was obtained from a calibration study conducted internally at Statistics Canada (publication under peer review; Colley and Tremblay, 2010).

29. AMMDLA1 – Total light physical activity – Day 1 (minutes per day)
Variable name:
AMMDLA1
Description:
Total light physical activity is derived using an intensity cut-point and is theoretically equivalent to 2-3 METs. The metabolic equivalent (MET) is a value of metabolic energy cost expressed as a multiple of the resting metabolic rate. For example, an activity of 4 METs requires four times the amount of energy as compared to when the body is at rest. The number of minutes where counts were greater than or equal to the sedentary cut-point (100 cpm) but less than the moderate physical activity cut-point were counted as light physical activity and summed for each valid day.
The cut-point to differentiate between sedentary and light activity (100 cpm for both children and adults) was based on a preliminary examination of CHMS data which used low step counts as a way of determining an appropriate count value to associate with sedentary behaviour (Wong, Colley et al. In Press; Journal of Physical Activity and Health).
The moderate cut-point used for children (1,500 cpm) was obtained from a calibration study that related Actical counts to measured energy expenditure (Puyau, Adolph et al., 2004). The moderate intensity cut-point used for adults (1,535 cpm) was obtained from a calibration study conducted internally at Statistics Canada (publication under peer review; Colley and Tremblay, 2010).

Description:
Time spent in bouts of moderate physical activity is derived using an intensity cut-point and is theoretically equivalent to > 3 and < 6 METs. The metabolic equivalent (MET) is a value of metabolic energy cost expressed as a multiple of the resting metabolic rate.

The number of minutes that were accumulated above the moderate cut-point and below the vigorous cut-point in bouts were counted as moderate physical activity (bouts) and summed for each valid day.
For children, moderate physical activity was counted as a bout if a minimum of 4 out of 5 consecutive minutes were above the moderate cut-point and below the vigorous cut-point. For adults, moderate physical activity was counted as a bout if a minimum of 8 out of 10 consecutive minutes were above the moderate cut-point and below the vigorous cut-point.

Variable name:
AMSDMB1
Description:
Time spent in bouts of moderate physical activity is derived using an intensity cut-point and is theoretically equivalent to > 3 and < 6 METs. The metabolic equivalent (MET) is a value of metabolic energy cost expressed as a multiple of the resting metabolic rate. For example, an activity of 4 METs requires four times the amount of energy as compared to when the body is at rest. The number of minutes that were accumulated above the moderate cut-point and below the vigorous cut-point in bouts were counted as moderate physical activity (bouts) and summed for each valid day.
For children, moderate physical activity was counted as a bout if a minimum of 4 out of 5 consecutive minutes were above the moderate cut-point and below the vigorous cut-point.

The cut-point to differentiate between inactivity and sedentary time was based on a preliminary examination of CHMS data which used low step counts as a way of determining an appropriate count value to associate with sedentary behaviour (Wong, Colley et al., In Press; Journal of Physical Activity and Health).
