Current and predicted prevalence of obesity in Canada: a trend analysis.

ABSTRACT:

Background

The prevalence of obesity has increased over the past 3 decades, with a disproportionate growth in excessive weight categories (body mass index [BMI] 35.0-39.9 and BMI ≥ 40.0). The objective of this paper is to present the data for the past and current prevalence of adult obesity in Canada, together with future estimates.

Methods

We calculated BMIs for adults aged 18 years and older who were not in long-term care using data from Canadian health surveys administered between 1985 and 2011. Calculation of the BMIs was based on self-reported heights and weights. The weight categories were as follows: normal (BMI 18.5-24.9), overweight (25.0-29.9), obese class I (30.0-34.9), obese class II (35.0-39.9) and obese class III (≥ 40.0). Outcome measures were prevalence of ad
