Introduction |
||||||||||||||||||||||||||||||||||||||||||||||||
The Canadian Community Health Survey collects self-report height and weight from respondents. All proportions shown here have been adjusted using a body mass index (BMI) adjustment factor to account for biases in self-reporting of height and weight, as recommended by Statistics Canada. BMI is calculated by using the formula: BMI=weight(kg)/height(m)2 Table A shows how BMI is classified into categories. For example, if someone has a BMI that is 27.6, they will be classified in the 'overweight' category.

Interpretation for Figure GIn Ontario, in higher income areas than lower income areas, a greater proportion of the population is overweight or obese. Notes on the income groupings:The income variable was based on a derived income variable from the CCHS. This variable provided a distribution of respondents in deciles based on the adjusted ratio of their total household income to the low income cut-off corresponding to their household and community size. It provides, for each respondent, a relative measure of their household income to the household incomes of all other respondents. The income variables used in this report were determined as follows: the lowest 3 deciles of the derived variable from CCHS were categorized into 'Lower Income', the middle 4 deciles were categorized into 'Middle Income' and the highest 3 deciles were categorized into 'Higher Income'. |

Confidence intervals explained | ||||||||||||||||||||||||||||||||||||||||||||||||
Researchers look at the "confidence levels" of percentages being compared to decide if there is a statistically significant difference between percentages. A statistically significant difference means that:
In this report, 95% confidence intervals will accompany each percentage in all figures and tables. This interval represents the range in which we are 95% confident the true percentage will fall within. In tables, the 95% confidence intervals will be written with the percentage, followed by the 95% confidence interval range in brackets (e.g., 25% (12.3, 32.4)). In figures, the 95% confidence interval is represented by vertical bars in each bar line. |
