Provide a method for translating pediatric blood pressures, dependent on age, sex, and height (if known), to percentiles.
Provide functions to get the percentiles for other growth standards.

Blood pressure percentiles are based on Gaussian distributions defined by published values for the mean and standard deviation, or derived mean and standard deviations based on published percentiles. Growth standards are based on LMS approximations. All the methods get parameters based on lookup tables.
There are several data sources used to inform the blood pressure percentiles estimates:
The default method is to use the workflow defined in Martin, DeWitt, et al. (2022).
End users may opt to use any single data source.
Example: A 28 month old female with a stature of 92 cm has a recorded blood pressure of 95/50. Find the percentiles.
library(pedbp)
p_bp(q_sbp = 95, q_dbp = 50, male = 0, age = 28, height = 92)
Selecting the source data is also possible
p_bp(q_sbp = 95, q_dbp = 50, male = 0, age = 28, height = 92, source = "martin2022") # Default
p_bp(q_sbp = 95, q_dbp = 50, male = 0, age = 28, height = 92, source = "gemelli1990")
p_bp(q_sbp = 95, q_dbp = 50, male = 0, age = 28, height = 92, source = "lo2013")
p_bp(q_sbp = 95, q_dbp = 50, male = 0, age = 28, height = 92, source = "nhlbi")
p_bp(q_sbp = 95, q_dbp = 50, male = 0, age = 28, height = 92, source = "flynn2017")
You can also find the quantile values. Example: what is the SBP/DBP values for the 42nd percentile of 13 year (156 month) old males in the 90th height percentile?
q_bp(p_sbp = 0.42, p_dbp = 0.42, age = 156, male = 1, height_percentile = 0.90)
More examples can be found in the vignette.
vignette("bp-distributions", package = "pedbp")
Growth standards based on both CDC and WHO data are provided in this package. Read more in the vignette
vignette(topic = "growth-standards", package = "pedbp")
Growth standards implemented in the package are:
bmi_for_age
head_circumference_for_age
height_for_age
length_for_age
weight_for_age
weight_for_length
weight_for_height
# Example: what is the percentile for a BMI of 23 in a 14.5 year old male?
p_bmi_for_age(q = 23, male = 1, age = 14.5*12, source = "CDC")
## [1] 0.8502674
p_bmi_for_age(q = 23, male = 1, age = 14.5*12, source = "WHO")
## [1] 0.8880632
