    Abstract:
    OBJECTIVE: To characterise consumption of ultra-processed foods and drinks (UPF) across a range of socio-demographic characteristics of Canadians. DESIGN: Cross-sectional study. The national-level 2015 Canadian Community Health Survey-Nutrition provided data on all foods and drinks consumed on the previous day via a 24-hour dietary recall. All food items were classified according to the type of industrial processing using the NOVA system. Multivariable linear regression models examined associations between a range of socio-demographic characteristics and the mean energy contribution (% of total daily energy intake) from total UPF and UPF subgroups. SETTING: The ten Canadian provinces. PARTICIPANTS: Canadians aged 2 or older (n 20 103). RESULTS: UPF contributed, on average, nearly half (44·9 %) of total daily energy intake of Canadians. Children aged 6-12 and adolescents aged 13-18 consumed over half of total daily energy from UPF (adjusted means of 51·9 % and 50·7 %, respectively). Recent and long-term immigrants consumed a significantly lower share of energy from UPF (adjusted means of 42·2 % and 45·1 %, respectively) compared with non-immigrants (54·4 %), as did the food secure (42·8 %) v. those in moderately (48·1 %) or severely food-insecure households (50·8 %). More modest differences were observed for intake of total UPF and UPF subgroups by sex, education, income adequacy and region of residence. CONCLUSION: Levels of UPF consumption in 2015 in Canada were pervasive in all socio-demographic groups and highest among children and adolescents, non-immigrants and those living in food-insecure households. These findings can inform public health interventions to reduce UPF consumption and promote healthier diets in various socio-demographic groups.
