Objectives. This study examined: the characteristics of Air Force recruits
willing to take part in a health survey vs those unwilling to participate.
Methods. US Air force recruits undergoing basic military training (n = 32 1
44) were surveyed regarding demographic and health variables.
Results Respondents indicating an unwillingness to participate in a health
survey reported less healthy lifestyles than those willing to participate.
Prediction equations modeling the characteristics of those engaging in 4 ri
sky behaviors were nearly identical regardless of whether those refusing to
participate were included.
Conclusions, Results suggest that, despite some Tow estimates of health. be
haviors duc to response bias, relationships between most risk factors are g
enerally unaffected by those not responding to health surveys.
