Height (cm) measured at study visit

height under Anthropometry in NUMOM2B variables

Height (corrected)

height under Anthropometry in HCHS variables

During two time periods the standing height as measured at the Bronx site was incorrect due to a mis-mounted stadiometer used in measuring all participants. The derived variable was implemented based on a recommendation from the Quality Control subcommittee.
