Reliability and validity of the weight status and dietary intake measures in the COMPASS questionnaire: are the self-reported measures of body mass index (BMI) and Canada’s food guide servings robust?

Abstract: BackgroundThe COMPASS study is designed to follow a cohort of ~30,000 grade 9 to 12 students attending ~60 secondary schools for four years to understand how changes in school characteristics (policies, programs, built environment) are associated with changes in youth health behaviours. Since the student-level questionnaire for COMPASS (Cq) is designed to facilitate multiple large-scale school-based data collections using passive consent procedures, the Cq is only comprised of self-reported measures.

“…A large sample of 5278 subjects aged 15-64 years was examined, in whom the use of questionnaires, as opposed to direct interview, was instrumental to enable the broadness of the sample, and to enhance its reliability, since it has been documented that participants feel more anonymous using a questionnaire [27]. Self-reported BMI from height and weight and dietary intake has been shown not to affect the association in epidemiological studies [28]. The EAT26 has been widely used to assess the risk of eating disorders, and has been validated in the Italian population [21].…”

“…The measures were based on existing national standards or surveillance tools where possible; questionnaire details and psychometric properties for some measures are available elsewhere. [28][29][30] Energy Drink Use Students were asked, "In a usual school week (Monday to Friday), on how many days do you do the following? …Drink highenergy drinks (Red Bull, Monster, Rock Star, etc.)…”

“…Consistent with the Canadian sedentary behaviour guidelines for youth, 3 respondents were classified as sedentary if they reported an average of more than two hours of screen time sedentary behaviour a day. Using previously validated measures of eating behaviour, 27 respondents were asked to report how many servings of fruits and/or vegetables they ate on a usual day. Consistent with the Canada Food Guide fruit and vegetable consumption recommendations for teens, 25 males who reported less than eight servings per day and females who reported less than seven servings per day were classified as having inadequate fruit and vegetable consumption.…”

“…Those who reported marijuana use once a month or more were classified as current marijuana users. Using previously validated measures of self-reported height and weight, 27 body mass index (BMI) was calculated for each student using the self-reported weight (kg) and height (m) (BMI = kg/m 2 ). Weight status was then determined using the BMI classification system of the World Health Organization based on age-and sexadjusted BMI cut-points.…”
