This study examines three specific questions about obesity and overweight, using a nationally representative sample of Canadians.
Are sociodemographic and lifestyle behaviors associated with body weight ?
Is body weight correlated with specific health outcomes ?
Has the prevalence of obesity in Canada changed since 1978 ?
Secondary data analysis of a cross-sectional survey.
SAMPLE : This study uses the 1994 National Population Health Survey (NPHS) by Statistics Canada.
It is a stratified random sample of 19600 Canadians across all provinces.
The results show that age, gender, education, birth place and region, are significantly associated with obesity.
When a lower criterion is used for overweight and obesity (body mass index, BMI =25), dummy variables for marital status and occupation are also significant.
Second, obesity is associated with poorer self-rated health, high blood pressure, heart disease, diabetes, arthritis, respiratory and stomach problems.
For those respondents who have a BMI score of 25 or greater, there is also an association with stroke.
Finally, it is unclear whether the prevalence of obesity has changed.
However, there appears to be a systematic difference between studies using actual height and weight measurements (anthropometric) vs self-reported measurements. (...)
