Summary
This technical memorandum reports on the pilot testing and evaluation of "Gettin' in Gear," a driver wellness program developed by the Federal Motor Carrier Safety Administration (FMCSA) and partners to address high health risk factors, turnover, and safety concerns in the trucking industry. The program was designed using a holistic approach and the Transtheoretical Model of behavior change, focusing on four core areas: Refueling (diet), Rejuvenating (exercise), Relaxing (stress management), and Relating (family/relationships). The study involved a six-month pilot test conducted in 1999 with 128 drivers from seven companies, including long-haul, short-haul, and bus operators. The experimental design consisted of four phases: recruitment, introduction, action, and evaluation. Participants received an introductory package, a health assessment, and monthly information packages tailored to their stage of change. Interventions included written and audio materials, coaching via letter, phone, or email, snack packs provided by some companies, and exercise memberships. While 128 drivers enrolled, only 54 completed the follow-up health assessment. Statistical analysis confirmed that the follow-up group was not significantly healthier at baseline than those who dropped out, aside from slightly better aerobic fitness, mitigating selection bias concerns. Results indicated significant improvements in lifestyle habits and physical risk factors among the 54 participants. Drivers showed statistically significant gains in Refueling habits, particularly in vegetable consumption and reduced intake of high-sugar foods. Rejuvenating habits improved significantly across all six measured areas, including increased frequency of heart-rate-elevating activities and strength exercises. Relaxing habits also showed significant total category improvement, though specific stress management behaviors changed less dramatically. Relating habits did not improve significantly, likely because participants already scored high in this area initially. Physically, participants demonstrated significant improvements in aerobic fitness, strength, and flexibility, as well as reductions in body mass index and blood pressure. However, health knowledge scores did not improve significantly; notably, accuracy in estimating personal cholesterol levels decreased. The study concludes that the "Gettin' in Gear" program effectively improved drivers' lifestyle habits and physical health metrics, particularly in areas where baseline needs were greatest. The findings support the efficacy of a structured, multi-component wellness intervention tailored to the unique constraints of professional drivers. The memorandum also outlines a marketing plan to promote the program, identifying obstacles such as cost concerns and low participation rates, and proposing strategies like industry-wide awareness campaigns and large-group presentations to facilitate broader adoption.
Key finding
Participants demonstrated statistically significant improvements in dietary habits, exercise frequency, and physical fitness parameters including aerobic fitness and strength after completing the wellness intervention.
