This function determines the hypertension status of a respondent based on their systolic and diastolic blood pressure measurements and medication usage.
Usage
determine_hypertension(
BPMDPBPS,
BPMDPBPD,
ANYMED2,
CCC_32 = 2,
CARDIOV = 2,
DIABX = 2,
CKD = 2
)Arguments
- BPMDPBPS
An integer representing the systolic blood pressure measurement of the respondent.
- BPMDPBPD
An integer representing the diastolic blood pressure measurement of the respondent.
- ANYMED2
An integer indicating whether the respondent is on medication for hypertension.
1: Yes
0: No
- CCC_32
An optional integer indicating whether the respondent is actually on medication for hypertension.
1: Yes
2: No (default)
- CARDIOV
An optional integer indicating the presence of cardiovascular disease, affecting medication status.
1: Yes
2: No (default)
- DIABX
An optional integer indicating the presence of diabetes, affecting blood pressure thresholds.
1: Yes
2: No (default)
- CKD
An optional integer indicating the presence of chronic kidney disease, affecting blood pressure thresholds.
1: Yes
2: No (default)
Value
An integer representing the hypertension status:
1: High blood pressure (BP ≥ 140/90 mmHg (or ≥ 130/80 mmHg if diabetes or CKD) or on hypertension medication)
2: Normal blood pressure (BP < 140/90 mmHg (or < 130/80 mmHg if diabetes or CKD) and not on hypertension medication)
NA(b): Invalid input or non-response
Examples
# Example 1: Respondent has systolic BP = 150, diastolic BP = 95, and on medication.
determine_hypertension(BPMDPBPS = 150, BPMDPBPD = 95, ANYMED2 = 1)
#> [1] 1
# Output: 1 (High blood pressure due to systolic BP, diastolic BP, and medication usage).
# Example 2: Respondent has systolic BP = 120, diastolic BP = 80, and not on medication.
determine_hypertension(BPMDPBPS = 120, BPMDPBPD = 80, ANYMED2 = 2)
#> [1] 1
# Output: 2 (Normal blood pressure as BP is below 140/90 mmHg and not on medication).
