Correlates of diet quality in the Quebec population.

摘要

Objective: To determine the correlates of a high-fat diet in urban, suburban and rural areas in Quebec, Canada. Design: A secondary analysis of data collected as part of a 5-year multifactorial, multisetting, community-intervention project. Setting: Urban, suburban and rural settings in Quebec, 1997. Subjects: Data were analysed from a sample of 5214 participants (2227 males and 2987 females; aged 18-64 years). A food-frequency questionnaire was completed and a global index of food quality was calculated. Logistic regression was used to identify the correlates of a diet high in total fats, saturated fat and cholesterol. Results: In both genders, lower level of education, smoking status, French and English languages compared with other languages spoken at home, and a rural environment were associated with poor diet quality. Having no intention to eat low-fat dairy products more often was associated with a high-fat diet. In men, obesity (body mass index of >=30 kg/m2) and absence of reported health problems were correlates of a high-fat diet; whereas in women, lower physical activity was a correlate. Conclusions: Future health interventions in Quebec should target people with low education, smokers and those living in a rural environment. Obese men and sedentary women should have access to specific dietetic resources.
