smk_former: Former smokers: time since quit and time as smoker

In STAPM/hseclean: Health Survey Data Wrangling

Former smokers: time since quit and time as smoker

Description

Cleans the data on the time since quitting and time spent as a regular smoker among former smokers.

Usage

smk_former(data)

Arguments

data	Data table - the Health Survey for England data.

Details

The main issue to be overcome is that in the Health Surveys for England 2015+, time since quit and time spent as a smoker is provided in categories rather than single years. We simulate the single years by just picking a value at random within the time interval.

We also fill missing data: for children 8-15 years, we assume that missing values for former smokers = 1 year. For adults, we fill missing values with the average value for each age, sex and IMD quintile subgroup.

Value

Returns an updated data table with:

• years_since_quit

• years_reg_smoker
