Vegetarianism and other eating practices among youth and young adults in major Canadian cities.

OBJECTIVE: To estimate the prevalence and sociodemographic characteristics of youth and young adults in major Canadian cities with self-reported vegetarian dietary practices and examine efforts to alter their diets.
DESIGN: Data were collected in autumn 2016 via web-based surveys. Respondents reported vegetarian dietary practices (vegan, vegetarian or pescatarian) and efforts in the preceding year to consume more or less of several nutrients, food groups and/or foods with particular attributes. Logistic regression models examined sociodemographic correlates of each vegetarian dietary practice and differences in other eating practices by diet type.
SETTING: Participants were recruited from five major Canadian cities. PARTICIPANTS: Youth and young adults, aged 16-30 years (n 2566).
RESULTS: Overall, 13·6 % of respondents reported vegetarian dietary practices: 6·6 % vegetarian, 4·5 % pescatarian and 2·5 % vegan. Sex, race/ethnicity, self-reported frequency of using the Nutrition Facts table and health literacy were significantly correlated with self-reported vegetarian dietary practice (P < 0·01 for all). Efforts to consume more fruits and vegetables (66·8 %) and protein (54·8 %), and less sugar (61·3 %) and processed foods (54·7 %), were prevalent overall. Respondents with vegetarian dietary practices were more likely to report efforts to consume fewer carbohydrates and animal products, and more organic, locally produced, ethically sourced/sustainably sourced/fair trade and non-GM foods (P < 0·01 for all), compared with those without these reported dietary practices.
CONCLUSIONS: Nearly 14 % of the sampled youth and young adults in major Canadian cities reported vegetarian dietary practices and may be especially likely to value and engage in behaviours related to health-conscious diets and sustainable food production.
