The New Zealand blood donors' health study is a large prospective cohort study designed to investigate relationships between lifestyle, psychosocial factors and serious injury. There were 22,389 participants recruited from blood donation sites, where exposure data were collected using a self-administered questionnaire.

The socioeconomic status (SES) variables collected in this study include job descriptions, education, and household income. These SES variables have the largest amount of missing information among all exposure data collected at baseline. This talk will look at our attempts to examine the completeness of data on variables relating to SES, and identify factors (such as age, sex, and ethnicity) which are related to whether a participant has a missing SES.
