#- Multinomial logistic regression is modelling the probablity of overweight and obesity
Ұ- Considered the reference category in the multinomial logistic regression
*- Considered reference category for the sociodemographic variable
a- Alberta’s Tomorrow Project baseline data, respondents to height and weight measurements
b- Continuous variable in years placed into categories
c- Completed high school
d- Completed some technical school/college training, or completed technical school/college training, or completed some part of university degree
e- Completed university degree, or completed some part of post-graduate university degree, or completed university post-graduate degree
f- Did not completed grade 8, or completed grade 8 but not high school
g- Single and never have been married
h- Divorced, or separated, or widowed
i- Married, or not married but living with a partner
j- Income data are in response to a question about total household income before tax
k- “Other” includes homemaker, unemployed, student and other category
l- Geographic Location was determined using postal codes, where the “0” as the middle numerical number indicates rural residence
† - Missing in body mass index or in at least one sociodemographic factor and hence excluded from the analysis (n = 259)
ǂ- Missing in body mass index or in at least one sociodemographic factor and hence excluded from the analysis (n = 697)
