What measured height weight data sources are available for Aboriginal, northern populations and children under 12 years of age based on the last CHMS. Thank you.

 Evan Green at 13:39:03
Hi Elsie,
Thanks for your questions. We collected measured height and weight data from Canadians, aged 3 to 79 not living on reserve. We do ask respondents to self-identify as Aboriginal, however we have not analysed results at that level.

 BABITA GUPTA at 13:36:00
The results are published at a pan-Canadian level. How do the results on COPD vary at the Provincial/Territorial level? Can any estimates be made at the P/T level from this data?

 Ben Leber at 13:46:03
Hello Babita,
Thank you for the question. The Canadian Health Measures Survey is designed to provide nationally representative data. The Canadian Community Health Survey on Chronic Conditions has data on self-reported COPD at a provincial or health region level.

 HealthReports at 13:37:00
What is the most interesting finding that you can share with us? Did anything jump out at you with this cycle, compared to self-reported survey data?

 Janine Clarke at 13:46:42
Good afternoon!
We compared measured and self-reported data for chronic obstructive pulmonary disease (COPD) and for blood pressure, and saw differences in each.
11% of Canadian adults (35 years and older) had a spirometry result consistent with COPD, but only 3% self-reported the condition.
Among adults (20 to 79 years) with measured high blood pressure, 16% were unaware of (did not self-report) the condition.

 Ling Liu at 13:34:00
Is fractional exhaled nitric oxide (FeNO) available Now? If not, when will the data be available?

 Janine Clarke at 13:48:48
Hi Ling Liu, the FeNO data was released with the rest of the clinic data yesterday!

 elsie de roose at 13:43:00
Thanks Evan - did you collect data in the 3 territories? If you could send the link to the data, that would be appreciated.

 Evan Green at 13:49:42
You're quite welcome, Elsie!
The CHMS had only collected data in the ten provinces. For more information about the sampling strategy, consult the Data sources and methodology section of the Canadian Health Measures Survey (CHMS), or you can take a look at our user guide.

 Charles Gilbert at 13:31:00
Good Afternoon. Charles Gilbert at PHAC here ... I am wondering at the diffential between self report and measured COPD?

 Ben Leber at 13:53:37
Hello Charles,
Self-reported COPD was determined from the health care questionnaire administered at the dwelling of the individual. The respondents were asked whether they had been diagnosed by a health care professional. The numbers showed 3% (572,067 of total population) self-reported a diagnosis of COPD.
Measured COPD was determined at the Mobile Examination Centre which travels across Canada conducting physical measures. COPD was measured using spirometry and the lower limit of normal for COPD guidelines. A total of 11% or 1,827,036 of the total population measured within the COPD guidelines.

Are there any early ways that the data are being used to shape health policy?

 Janine Clarke at 13:56:30
Statistics Canada is only responsible for the collection and dissemination of the data, but the data is available to our share partners - Health Canada and the Public Health Agency of Canada - as of yesterday. I unfortunately do not know what they have planned.

 fanofstats at 13:34:00
At the end of the several cycle 3 data releases, will there also be some kind of report with ways the government plans to help change/modify the physical measures of Canadians (such as the proportion of Canadians considered to be obese, for example)?

 at 14:01:00
Hi fanofstats,
Thank you for your question. The design and implementation of new policies is within the mandate of policy departments, such as Health Canada or the Public Health Agency of Canada. Statistics Canada provides statistics that help to inform such decisions. You may wish to contact those departments directly for more informaton on that request.

 Moderator at 14:06:00
Thank you for your questions. We still have time, don't hesitate to send more!

 Lucie at 14:04:00
Hi, you say that obesity is linked to a number of chronic illnesses, including high blood pressure, Type 2 diabetes, cardiovascular diseases, arthritis and certain types of cancer. What types of cancer?

 Joel Roy at 14:18:26
Hi Lucie.
Thank you for your question. The CHMS did not establish a direct correlation between obesity and cancer based on the data collected. However, the references in the release (Health Canada and the Public Health Agency of Canada) show that excess weight is linked to an increased risk of kidney, colorectal and pancreatic cancer.

 Charles Gilbert at 14:13:00
Will we get feedback if our question is not answered in live chat hour?

 at 14:18:30
Hi Charles,
The answer from the expert is posted under the question that you submitted earlier. To see it, please scroll down or refresh your browser.

 HealthReports at 14:01:00
Is it possible to do a rural/urban analysis with the results from the survey, at the national level?

 Janine Clarke at 14:19:56
Hi, thanks for your question!
We do collect data from both urban and rural residents, but we don't include this information on our data file to determine urban or rural status, and therefore cannot do that type of analysis. I believe this type of comparison can be done using the Canadian Community Health Survey data, which has a much larger sample size from more areas around the country compared to the CHMS.

 fanofstats at 14:23:00
In yesterday's release, you state that 31% of children and youth aged 5 to 17 were overweight or obese, based on their measured BMI… Any stats on children under the age of 5 years old? If not, any plans to start collecting such data in the future?

 Evan Green at 14:27:35
Thanks for your question fanofstats!
We do collect measured height and weight information to calculate BMI for 3- and 4-year-olds, however they were not included for this fact sheet. The data are available and statistics on these individuals could definitely be published in the future.

 Charles Gilbert at 14:31:47
Thank you to all the panelist for taking and answering our questoins. Much appreciated.

 mpennock at 14:26:00
What are the BMI levels for adults and children/youth that are considered as overweight or obese?

 Evan Green at 14:32:34
Hi mpennock,
Thanks for your question.  For adults, the BMI cutoff for overweight is 25 to 29.99 kg/m&³2;, and for obese it is 30 kg/m&³2; and above.  For children and youth, there aren't specific values because the groupings are based on the World Health Organization (WHO) BMI-for-age growth references.

 Lucie at 14:26:00
What regions in Canada have the highest rates of obesity among children?

 Joel Roy at 14:37:23
Hi Lucie.
Unfortunately, the CHMS design does not allow the results to be analyzed below the national level. The Canadian Community Health Survey (CCHS), another health survey conducted by Statistics Canada, is based on a larger sample, allowing analysis at a provincial or health region level.

 macdon2 at 14:27:00
Hello, if possible, could you please expand on how/if disability type or severity in the collection of the data was used? This would be dependent on how a person qualifies the diagnosis of a disability.

 Janine Clarke at 14:44:38
Hi macdon2, thanks for your question.
We collect a lot of information related to various diseases and disabilities, some of which are self-identified through questionnaires, and some can be determined through analysis of direct measures. In cycle 3, we have a section on chronic conditions at the household level, but most of these questions are simply yes/no responses to the diagnosis of various conditions. We do ask detailed information on hearing abilities and also have measured otoscopy, audiometry, tympanometry, and otoacoustic emissions that will be available in March 2015.
Previous and future cycles of the CHMS have a series of questions related to mobility, vision, hearing, and pain in a section called the Health Utility Index.
If you want to know more, you can obtain a copy of our Content Summary document and/or copies of the questionnaires from cycles 1 to 4 by contacting STATCAN.infostats-infostats.STATCAN@canada.ca.

 Moderator at 14:30:00
The chat session is now over. Thank you for your questions and comments! If our experts did not have a chance to respond to your questions, we will follow-up with you by email in the next few business days. The full transcript of this chat session will be made available on our website shortly. Have a great day!
