Adjusted diastolic blood pressure — adjust

This function adjusts diastolic blood pressure based on the respondent's diastolic average blood pressure across six measurements. The adjustment is made using specific correction factors. The adjusted diastolic blood pressure is returned as a numeric value.

Usage

adjust_DBP(BPMDPBPD)

Arguments

BPMDPBPD: A numeric representing the respondent's diastolic average blood pressure (in mmHg) across six measurements.

Value

The adjusted diastolic blood pressure as a numeric value.

Details

The function calculates the adjusted diastolic blood pressure (DBP_adj) based on the value of BPMDPBPD. If BPMDPBPD is greater than or equal to 0 and less than 996, the adjustment is made using the formula: DBP_adj = 15.6 + (0.83 * BPMDPBPD). Otherwise, if BPMDPBPD is a non-response value (BPMDPBPD >= 996), the adjusted diastolic blood pressure is set to NA(b), indicating that the measurement is not available. The adjusted diastolic blood pressure is returned as the final output.

Examples


# Example: Adjust for a respondent with average diastolic blood pressure of 80 mmHg.
adjust_DBP(BPMDPBPD = 80)
#> [1] 82
# Output: 82
