Hypertension derived variable with adjusted blood pressures

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

Usage

determine_adjusted_hypertension(
  SBP_adj,
  DBP_adj,
  ANYMED2,
  CCC_32 = 2,
  CARDIOV = 2,
  DIABX = 2,
  CKD = 2
)

Arguments

SBP_adj

An integer representing the adjusted systolic blood pressure measurement of the respondent.

DBP_adj

An integer representing the adjusted 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 (adjusted BP ≥ 140/90 mmHg (or ≥ 130/80 mmHg if diabetes or CKD) or on hypertension medication)

• 2: Normal blood pressure (adjusted 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 adjusted SBP = 150, adjusted DBP = 95, and on medication.
determine_adjusted_hypertension(SBP_adj = 150, DBP_adj = 95, ANYMED2 = 1)
#> [1] 1
# Output: 1 (High blood pressure due to adjusted SBP, adjusted DBP, and medication usage).

# Example 2: Respondent has adjusted SBP = 120, adjusted DBP = 80, and not on medication.
determine_adjusted_hypertension(SBP_adj = 120, DBP_adj = 80, ANYMED2 = 2)
#> [1] 1
# Output: 2 (Normal blood pressure as adjusted BP is below 140/90 mmHg and not on medication).
