A cross-sectional survey will be completed by 418 participants from several administrative regions of Québec (Canada). A special effort will be made to recruit men and women with low socioeconomic status (SES), but without rejecting adults from middle/high SES. First, 325 adults from low SES (high school or less and gross annual household income < $55,000 canadian) and from several administrative regions of Québec will be identified by a survey firm. In addition, an e-mail mailing list from the Institute of Nutrition and Functional Food (INAF, Laval University) will be used to distribute the recruitment ad to complete our sample (n=93 from all SES).~The survey is based on the Theory of Planned Behaviour and assesses intention to participate in NutriQuébec as well as attitude, subjective norm, and perceived behavioural control. The salient beliefs underlying the determinants of individual's intention to participate in the NutriQuébec study most frequently cited in the focus groups (from a preliminary elicitation study: 2018-042 A-1/18-05-2018) were used to develop the survey questions. The survey also assesses the preferences regarding the recruitment. Sociodemographic questions are also asked.
Populations with low socioeconomic status (SES) are more likely to develop diseases across lifespan and are frequently underrepresented in large cohort studies. The aim of this study is to examine beliefs, preferences and concerns towards participating in an e-cohort prospective study on nutrition (NutriQuébec) among this population.~A cross-sectional survey will be completed by 418 adults in the Province of Québec (Canada), including individuals with low SES (high school or less and gross annual household income < $55,000 canadian). The survey is based on the Theory of Planned Behaviour and assesses intention to participate in NutriQuébec as well as attitude, subjective norm, and perceived behavioural control. The survey also assesses preferences regarding the recruitment.
