*Townsend score of deprivation is an index made up of unemployment, overcrowding, non-car ownership and non-home ownership, where 1 represents lower degree of deprivation and 5 represents higher degree of deprivation.
†Calendar year refers to the calendar year in which the baseline data were collected to account for any time trends.
BMI, body mass index; HDL, high-density lipoprotein; SBP, systolic blood pressure; SMI, severe mental illness.
