Controlled hypertension derived variable

This function determines the controlled hypertension status of a respondent based on their systolic and diastolic blood pressure measurements and medication usage.

Usage

determine_controlled_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: Hypertension controlled (BP < 140/90 mmHg (or < 130/80 mmHg if diabetes or CKD) when on hypertension medication)

• 2: Hypertension not controlled (BP ≥ 140/90 mmHg (or ≥ 130/80 mmHg if diabetes or CKD) when 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_controlled_hypertension(BPMDPBPS = 150, BPMDPBPD = 95, ANYMED2 = 1)
#> [1] 2
# Output: 2 (Hypertension not controlled due to high SBP and SBP despite medication usage).

# Example 2: Respondent has systolic BP = 120, diastolic BP = 80, and on medication.
determine_controlled_hypertension(BPMDPBPS = 120, BPMDPBPD = 80, ANYMED2 = 1)
#> [1] 1
# Output: 1 (Hypertension controlled as BP is below 140/90 mmHg and on medication).
