A big study of Canadians BMI, and does body mass index affect health?
This article used the standard WHO criteria1 for body mass index, defining BMI > 25.0 as "overweight" and BMI>30.0 as "obese".
However, the article mentions a specific Canadian BMI criteria, which is BMI<20.0 is "underweight", BMI >25.0 is "some excess weight", and BMI>27.0 is "overweight".
This study used fairly recent data from 1996-1997. Here are some descriptive statistics about Canadians:
Average height of women (Canadian) is 163 centimeters, or 5 feet 4 inches.
Average weight of women (Canadian) is 65.8 kg, or 145 pounds.
Average Body Mass Index (BMI) of Canadian women is 24.8 kg/m2.
Average height of men (Canadian) is 178 centimeters, or 5 feet 10 inches.
Average weight of men (Canadian) is 83.2 kg, or 183 pounds.
Average Body Mass Index (BMI) of Canadian men is 26.3 kg/m2.
The study found that being overweight is associated with health risks. These types of illnesses occurred much more frequently in overweight people: asthma, arthritis, back problems, high blood pressure, diabetes, thyroid problems, activity limitations, repetitive strain injury.
