  1. OR odds ratio, CI confidence interval, *p < 0.05
  2. a - All multivariable models were adjusted for age, gender, geographic region (7 main regions: North, Center, Lisbon region, Alentejo, Algarve, Azores and Madeira), marital status, education level, household income, body mass index and chronic diseases. Cofactors were excluded in the stepwise method if p > 0.05 (except for age and gender)
