  1. † Denotes variables used in cluster analyses. aPost-hoc refers to the significant differences between clusters. bFor self-rated general health 0 = excellent, 4 = poor.
  2. Note. The clusters were the same whether listwise deletion or missing data imputation was used. The more conservative listwise approach was used.
