OR = Odds Ratio, WC = Waist circumference; 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: waist circumference + socio-occupational class + self-declared colour or race + age + marital status + waist circumference*socio-occupational class; * Effect of socio-occupational class status considering waist circumference
