Walking Through the Process of SGBA in Evidence
Let’s have a look at the example of Obesity.
This activity will take you through a sex- and gender-based analysis of evidence in the topic area of obesity. Suppose that you have been asked to look for evidence about what contributes to obesity, particularly as it relates to diet.
Your first step in searching for evidence about obesity brings you to a comparison of self-reported and measured Body Mass Index – see Chart A. Have a look at this chart which describes changes in body mass index over time.
Chart A. Trends in obesity rates, household population aged 18 year or older, Canada, excluding territories, selected years 1978/79 to 2004. 
Questions: What evidence does the chart provide to you? What evidence do you not have?
