In cchsflow: Transforming and Harmonizing CCHS Variables

Short term risks due to drinking

Description

This function creates a categorical variable that flags for increased short term health risks due to their drinking habits, according to Canada's Low-Risk Alcohol Drinking Guideline.

Usage

low_drink_short_fun(
  DHH_SEX,
  ALWDWKY,
  ALC_1,
  ALW_1,
  ALW_2A1,
  ALW_2A2,
  ALW_2A3,
  ALW_2A4,
  ALW_2A5,
  ALW_2A6,
  ALW_2A7
)

Arguments

DHH_SEX	Sex of respondent (1 - male, 2 - female)
ALWDWKY	Number of drinks consumed in the past week
ALC_1	Drinks in the past year (1 - yes, 2 - no)
ALW_1	Drinks in the last week (1 - yes, 2 - no)
ALW_2A1	Number of drinks on Sunday
ALW_2A2	Number of drinks on Monday
ALW_2A3	Number of drinks on Tuesday
ALW_2A4	Number of drinks on Wednesday
ALW_2A5	Number of drinks on Thursday
ALW_2A6	Number of drinks on Friday
ALW_2A7	Number of drinks on Saturday

Details

The classification of drinkers according to their short term health risks comes from guidelines in Alcohol and Health in Canada: A Summary of Evidence and Guidelines for Low-risk Drinking, and is based on the alcohol consumption reported over the past week. Short-term or acute risks include injury and overdose.

Categories are based on CCHS 2015-2016's variable (ALWDVSTR) where short term health risk are increased when drinking more than 3 drinks (for women) or 4 drinks (for men) on any single occasion.

See https://osf.io/ykau5/ for more details on the guideline. See https://osf.io/ycxaq/ for more details on derivation of the function on page 9.

Value

Categorical variable (ALWDVSTR_der) with two categories:

• 1 - Increased short term health risk

• 2 - No increased short term health risk

Examples

 
# Using low_drink_short_fun() to create ALWDVSTR_der values across CCHS cycles
# low_drink_short_fun() is specified in variable_details.csv along with the
# CCHS variables and cycles included.

# To transform ALWDVSTR_der, use rec_with_table() for each CCHS cycle
# and specify ALWDVSTR_der, along with the various alcohol and sex
# variables. 
# Using merge_rec_data(), you can combine ALWDVSTR_der across cycles.

library(cchsflow)
short_low_drink2001 <- rec_with_table(
  cchs2001_p, c(
    "ALW_1", "DHH_SEX", "ALW_2A1", "ALW_2A2", "ALW_2A3", "ALW_2A4",
    "ALW_2A5", "ALW_2A6", "ALW_2A7", "ALWDWKY", "ALC_1","ALWDVSTR_der"
  )
)

    "ALW_2A5", "ALW_2A6", "ALW_2A7", "ALWDWKY", "ALC_1","ALWDVSTR_der"
  )

# Using low_drink_short_fun() to generate ALWDVSTR_der with user-inputted
# values.
#
# Let's say you are a male, you had drinks in the last week and in the last 
# year. Let's say you had 5 drinks on Sunday, 1 drink on Monday, 6 drinks on 
# Tuesday, 4 drinks on Wednesday, 4 drinks on Thursday, 8 drinks on Friday, 
# and 2 drinks on Saturday with a total of 30 drinks in a week. 
# Using low_drink_short_fun(), we can check if you would be classified as
# having an increased short term health risk due to drinking.

short_term_drink <- low_drink_short_fun(DHH_SEX = 1, ALWDWKY = 30, ALC_1 = 1,
 ALW_1 = 1, ALW_2A1 = 5, ALW_2A2 = 1, ALW_2A3 = 6, ALW_2A4 = 4, ALW_2A5 = 4, 
 ALW_2A6 = 8, ALW_2A7 = 2)

print(short_term_drink)
