The relationship between Canada's Food Guide (CFG) adherence and overweight/obesity at the population level is unknown. Our objective was to explore the association between overweight/obesity and CFG adherence in Canada.
Using 24-h dietary recall data from the Canadian Community Health Survey (CCHS), we conducted a cross-sectional analysis of Canadians' consumption of four predefined food types from CFG (grain products, vegetables and fruit, milk and alternatives, meat and alternatives). Respondents aged 18 to 65 years with measured BMI were included. The total number of servings in each food group was compared with the number of recommended servings in CFG to determine adherence. Linear regression was used to explore the association between overweight/obesity and CFG adherence.
Participants who met the minimum servings in vegetables and fruit had a lower measured BMI. Also, participants who met the minimum servings in meat and alternatives had a higher measured BMI. These associations were observed for the sample as a whole and for those with overweight/obesity, and, for meat and alternatives, among women.
There is evidence that following the CFG recommendation is associated with measured BMI, for some food groups. This relationship needs to be validated using longitudinal data.
加拿大食物指南（CFG）的遵循情况与人群超重/肥胖之间的关系尚不清楚。我们的目的是探讨加拿大超重/肥胖与CFG遵循情况之间的关联。
利用加拿大社区健康调查（CCHS）的24小时饮食回忆数据，我们对加拿大人从CFG中四种预定义食物类型（谷物产品、蔬菜和水果、牛奶及替代品、肉类及替代品）的消费情况进行了横断面分析。纳入年龄在18至65岁且测量了BMI的受访者。将每个食物组的总份数与CFG中推荐的份数进行比较，以确定遵循情况。使用线性回归来探讨超重/肥胖与CFG遵循情况之间的关联。
达到蔬菜和水果最低份数要求的参与者测量的BMI较低。此外，达到肉类及替代品最低份数要求的参与者测量的BMI较高。在整个样本以及超重/肥胖者中观察到了这些关联，对于肉类及替代品，在女性中也观察到了这种关联。
有证据表明，对于某些食物组，遵循CFG建议与测量的BMI相关。这种关系需要使用纵向数据进行验证。
