  • Bold figures indicate that the results are statistically significant at the level of 5%

  • *aORs are reported only for those factors included in the logistic model with explanatory factors: season, housing tenure, socioeconomic status, household crowding and the RHI as a categorical variable (ORs for the housing quality measures are reported in tables 1 and 3).

  • †Total ethnicity reports individuals in each of the ethnicities they have listed and therefore may count individuals more than once if they have reported multiple ethnicities. The OR uses all those not reporting the given ethnicity as the reference group.

  • aOR, adjusted OR; NZiDep, New Zealand Index of Socioeconomic Deprivation.
