resp_condition_fun2 {cchsflow}

resp_condition_fun2

Description

This is one of 3 functions used to create a derived variable (resp_condition_der) that determines if a respondents has a respiratory condition. This function is for CCHS cycles (2005-2007) that use COPD & Emphysema as separate variables, as well as Bronchitis. Asthma is used across CCHS cycles as a separate variable.

Usage

resp_condition_fun2(DHHGAGE_cont, CCC_91E, CCC_91F, CCC_91A, CCC_031)

Arguments

DHHGAGE_cont

continuous age variable.

CCC_91E

variable indicating if respondent has emphysema

CCC_91F

variable indicating if respondent has COPD

CCC_91A

variable indicating if respondent has chronic bronchitis

CCC_031

variable indicating if respondent has asthma

Value

a categorical variable (resp_condition_der) with 3 levels:

1. respondent is over the age of 35 and has a respiratory condition

2. respondent is under the age of 35 and has a respiratory condition

3. respondent does not have a respiratory condition

Examples

# Using resp_condition_fun2() to create values across CCHS cycles
# (2005-2007) resp_condition_fun2() is specified in
# variable_details.csv along with the CCHS variables and cycles included.

# To transform resp_condition_der, use rec_with_table() for each CCHS cycle
# and specify resp_condition_der, along with the various respiratory
# variables. Then by using merge_rec_data() you can combine
# resp_condition_der across cycles.
