  1. OR = Odds Ratio, BMI = Body mass index; Ordinal logistic model was a proportional odds regression to model self-rated health (good, fair, poor). Crude and adjusted ORs were obtained by single and multicovariate models; Adjusted model: body mass index + socio-occupational class + self-declared colour or race + age + marital status + body mass index*socio-occupational class; * Effect of socio-occupational class status considering body mass index
