Abstract

BACKGROUND:

The contribution of specific nutrients to obesity has not been definitively established. The objective of this study was to determine if an association exists between obesity and the relative percentages of fats, carbohydrates, protein and fibre in the diets of Canadians.

DATA AND METHODS:

The data are from the 2004 Canadian Community Health Survey--Nutrition. The analysis pertains to 6454 respondents aged 18 or older who provided valid 24-hour dietary recall information and measured height and weight, and whose reported energy intake was considered plausible based on their predicted energy expenditure. Logistic regression models with obesity status as the main outcome were conducted, controlling for potential confounders. All analyses were based on weighted estimates.

RESULTS:

When the effect of the control variables was taken into account, total kilocalories consumed increased the odds of obesity in men, and fibre intake decreased the odds. Among women, only total kilocalories consumed was significantly associated with increased odds of obesity.

INTERPRETATION:

Higher consumption of kilocalories increased the odds of obesity, but the relative amounts of fats, carbohydrates and protein were generally not significant. The sole exception was an association between higher fibre intake and lower rates of obesity among men.
