A COMPARISON BETWEEN SELECTED HEALTH SCREENING AND HEALTH RISK APPRAISAL (HRA) VARIABLES OF HEALTH STATUS AND HEALTH RISK (WORKSITE, HEALTH PROMOTION, MULTIVARIATE)

Abstract

The purpose of this study was to determine the relationships between two sets of variables indicative of health status and health risk, taken from the same population. The first set was obtained during a worksite health screening program, while the second set consisted of self reported variables from a computerized health risk appraisal (HRA). Two hundred ninety-six females and thirty-nine males completed the HRA prior to participating in a health screening program that ascertained the following variables: exact age, height, weight, systolic blood pressure, diastolic blood pressure, non-fasting serum cholesterol, high density lipoprotein, carboxyhemoglobin, hemoglogin, and blood glucose. The HRA utilized during this study was supplied by the Centers for Disease Control, Atlanta, Georgia, through the Indiana State Board of Health, Health Education Division.^ Approximately six months following the initial data collection, a follow-up screening was conducted. Ninety-five females participated in the study as repeat participants. In addition, eighty-eight females participated in the study as first-time participants at the follow-up screening.^ Within the limitations of the study, the following conclusions were drawn: (1) The Centers for Disease Control (CDC) health risk appraisal (HRA) is an accurate estimator of health status and health risk for groups of females, when used as part of an overall worksite health promotion program. (2) There exists a clear inter-relationship between LAB measures of health status and HRA indicators of risk. (3) The HRA measure AAMAA (risk appraisal age minus actual age) clearly discriminates between high, average and below average levels of LAB measured variables for females. (4) The HRA as an indicator of health risk should not be taken as an accurate individual prediction, as misclassification for some individuals remains high. (5) Results of the initial analyses were confirmed with repeat participants six months later, except for a reduction in the accuracy of the HRA measures systolic and diastolic blood pressure. (6) The results of the initial analyses were replicated six months later with an additional group of females participating in the program for the first time. ^
