Average resting diastolic blood pressure of three measurements collected from the upper arm in a single clinic visit. 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 FC-specific normalized sample weight is the field center specific normalized, calibrated, trimmed, non-response adjusted (household and person-level) reciprocal of a participant's probability of selection into the HCHS/SOL study. The calibrated, trimmed, non-response adjusted sample weights were normalized using the weighted mean divided by weighted standard deviation calculated for each field center separately and used to normalize the expanded calibrated sample weights (WEIGHT_Final_Norm_Center). This final sample weight variable is used for analyses purposes only when the subpopulation is restricted to within a single site.

Note: This variable was derived from race and was not asked as a separate demographic question. At the time of SHHS Visit 1, race and ethnicity were collected together in a single question. This variable was derived later on when the datasets were prepared for deposition in Biologic Specimen and Data Repository Information Coordinating Center (BioLINCC).

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.
