SMKDSTY_fun: Type of smokers

Description

This function creates a derived variable (SMKDSTY_A) for smoker type with 5 categories:

• daily smoker

• current occasional smoker (former daily)

• current occasional smoker (never daily)

• current nonsmoker (former daily)

• current nonsmoker (never daily)

• nonsmoker

Usage

SMKDSTY_fun(SMK_005, SMK_030, SMK_01A)

Arguments

SMK_005

type of smoker presently

SMK_030

smoked daily - lifetime (occasional/former smoker)

SMK_01A

smoked 100 or more cigarettes in lifetime

Value

value for smoker type in the SMKDSTY_A variable

Details

For CCHS 2001-2014, smoker type is derived from smoking more than 100 cigarettes in lifetime, type of smoker at present time, and ever smoked daily. For CCHS 2015-2018, smoker type was derived differently with different variables and categories. A function was created for a consistent smoker status across all cycles.

Examples

# NOT RUN {
 
# Using SMKDSTY_fun() to derive smoke type values across CCHS cycles
# SMKDSTY_fun() is specified in variable_details.csv along with the 
# CCHS variables and cycles included.

# To transform SMKDSTY_A across cycles, use rec_with_table() for each
# CCHS cycle and specify SMKDSTY_A.
# For CCHS 2001-2014, only specify SMKDSTY_A for smoker type.
# For CCHS 2015-2018, specify the parameters and SMKDSTY_A for smoker type.
