Poor Adherence to Dietary Guidelines Among French-Speaking Adults in the Province of Quebec, Canada: The PREDISE Study.

BACKGROUND: Regular monitoring of the population's food and nutrient intake is essential to develop effective nutrition-focused public health policies. The aim of this study was to provide dietary intake estimates using an age- and sex-representative sample of French-speaking adults with Internet access from 5 administrative regions in the province of Quebec, Canada.

METHODS: PRÉDicteurs Individuels, Sociaux et Environnementaux (PREDISE) is a multicentre cross-sectional study that used a Web-based approach to collect individual, social, and environmental data on factors associated with adherence to dietary recommendations. Dietary intake was estimated from the average of 3 validated Web-based 24-hour recalls.

RESULTS: Mean (± SD) age of the 1147 participants (50.2% women) was 43.2 ± 4.6 years and median body mass index was 26.3 (interquartile range, 23.3-30.3). Less than 25% of participants met Canada's Food Guide recommendations for vegetables and fruit intake (prevalence, 23.6%; 95% confidence interval [CI], 21.1-26.0). Most participants reported consuming more than 2300 mg of sodium (prevalence, 80.5%; 95% CI, 78.2-82.7) and more than 10% energy as saturated fats (prevalence, 74.2%; 95% CI, 71.6-76.7). Mean Canadian Healthy Eating Index score on a scale of 0-100 was 54.5 (95% CI, 53.8-55.2), reflecting relatively poor diet quality according to current dietary recommendations.

CONCLUSIONS: Self-reported dietary intakes measured using a new validated Web-based 24-hour recall in this sample of French-speaking adults from Quebec and with access to Internet suggest low adherence to current Canadian dietary guidelines. These data emphasize the need for more effective nutrition-focused public health policies to maximize cardiovascular disease prevention at the population level.
