Average resting diastolic blood pressure of two measurements collected from the upper arm in a single clinic visit. When more than two measurements were collected, the average was calculated using the second and third measurements. In cases where either of the measurements was missing, the average was calculated discarding the missing value. Harmonized by the NSRR team to align with TOPMed and BioDataCatalyst standards.

The subscale score is based on 2 items from the Child Health Questionnaire Parent Form 50 Questions. A high score suggests less bodily pain. Asmussen L et al., 2000 (PubMed ID: 11029320)Search for all CHQ-PF50 variables within this dataset

The subscale score is based on 2 items from the Medical Outcomes Study Short Form 36 (SF-36). A high score suggests the participant has "no pain or limitations due to pain in the past 4 weeks". Ware JE and Sherbourne CD, 1992 (PubMed ID: 1593914)Search for all SF-36 variables within this dataset

Hypertension is defined here if the systolic or diastolic blood pressure is greater than or equal to 140/90 or if the participant is currently taking antihypertensive medications.
