  1. PR prevalence ratio, CI confidence interval.
  2. Only variables whose p value were < 0.10 were shown in the table and others described below were omitted. Results for each variable were shown only for the block at which the variable was entered first. Blocks 2, 3, 7 and 8 were not presented because no significant variables were kept at these blocks.
  3. Block 1: adjusted for age.
  4. Block 2: adjusted for variable kept in block 1(age) plus variables from block 2.
  5. Block 3: adjusted for variable kept in block 1(age) plus variables from block 3.
  6. Block 4: adjusted for variable kept in block 1(age) plus variables from block 4.
  7. Block 5: adjusted for variable kept in block 1(age), variable selected from block 4 (child has visited the dentist) plus variables from block 5.
  8. Block 6: adjusted for variable kept in block 1(age), variable selected from block 4 (child has visited the dentist), variables selected from block 5 (frequency of sucrose consumption between main meals, nighttime breastfeeding after 1 year, and use of a night bottle) plus variables from block 6.
  9. Block 7: adjusted for variable kept in block 1(age), variable selected from block 4 (child has visited the dentist), variables selected from block 5 (frequency of sucrose consumption between main meals, nighttime breastfeeding after 1 year and use of a night bottle), variable selected from block 6 (who does the teeth brushing) plus variables from block 7.
  10. Block 8: adjusted for variable kept in block 1(age), variable selected from block 4 (child has visited the dentist), variables selected from block 5 (frequency of sucrose consumption between main meals, nighttime breastfeeding after 1 year and use of a night bottle), variable selected from block 6 (who does the teeth brushing) plus variables from block 8.
