ABSTRACT
PURPOSE: This study explored employee health behavior changes and health care utilization after workplace genetic testing (wGT). Wellness-program-associated wGT seeks to improve employee health, but the related health implications are unknown. METHODS: Employees of a large US health care system offering wGT (cancer, heart disease, and pharmacogenomics [PGx]) were sent electronic surveys. Self-reported data from those who received test results were analyzed. Descriptive statistics characterized responses, whereas logistic regression analyses explored correlates of responses to wGT. RESULTS: 53.9% (n = 418/776) of respondents (88.3% female, mean age = 44 years) reported receiving wGT results. 12.0% (n = 48/399) received results indicating increased risk (IR) of cancer, 9.5% (n = 38/398) had IR of heart disease, and 31.4% (n = 125/398) received informative PGx results. IR results for cancer and/or heart disease (n = 67) were associated with health behavior changes (adjusted odds ratio: 3.23; 95% CI 1.75, 6.13; P < .001) and health care utilization (adjusted odds ratio: 8.60; 95% CI 4.43, 17.5; P < .001). Informative PGx results (n = 125) were associated with medication changes (PGx-informative: 15.2%; PGx-uninformative: 4.8%; P = .002). CONCLUSION: This study explored employee responses to wGT, contributing to the understanding of the ethical and social implications of wGT. Receiving IR results from wGT may promote health behavior changes and health care utilization in employees.

Workplace wellness programs are an emerging avenue for health-related genetic testing, with some large employers now offering such testing to employees. Employees' knowledge and concerns regarding genetic discrimination may impact their decision-making about and uptake of workplace genetic testing (wGT). This study describes employed adults' objective knowledge of the Genetic Information Nondiscrimination Act (GINA) and evaluates how this knowledge correlates with attitudes and beliefs regarding wGT. Analyses utilized data from a large, national web-based survey of employed adults (N = 2000; mean age = 43 years; 51% female; 55.2% college educated). Overall, most respondents (57.3%) said they were unaware of any laws protecting against genetic discrimination. Specifically, 62.6% indicated they were not at all familiar with GINA. The primary study outcome was respondents' score on a 13-item measure assessing knowledge of basic facts about GINA. Participants had low overall GINA knowledge (M = 4.6/13 items correct (35%), SD = 2.9), with employees often presuming GINA offers greater legal protections than it does (e.g., 45.3% erroneously endorsed that GINA protected against discrimination in life insurance). Logistic regression analyses assessed associations between GINA knowledge and employees' demographic characteristics, prior experience with genetic testing, and attitudes regarding wGT. Variables significantly associated with GINA knowledge included higher interest in wGT (aOR = 1.45; 95% CI: 1.20, 1.77), self-reported familiarity with GINA (aOR = 2.02; 95% CI: 1.64, 2.50), and favorable attitudes toward wGT (aOR = 1.92; 95% CI: 1.52, 2.44). Results indicate public knowledge of GINA remains low over 15 years after its passage. These findings highlight the need for employee education on GINA before participating in wGT, as well as broader public education on GINA's legal protections and limitations. Genetic counselors lead GINA education efforts in clinical and public settings and can play a pivotal role in ongoing public education initiatives about GINA.
