Modifiable Healthy Lifestyle Behaviors: 10-Year Health Outcomes From a Health Promotion Program.

INTRODUCTION: Previous studies have examined the impact of healthy lifestyle choices on health-related outcomes; however, given their fragmented, often cross-sectional nature, assessing the relative impact of daily modifiable behaviors on overall long-term outcomes, particularly for a diverse working adult population, remains challenging. METHODS: Relationships between ten self-reported healthy lifestyle behaviors and health outcomes during the subsequent 9 years in a cohort of 10,248 participants enrolled during 2003 in a voluntary workplace wellness program were assessed. Cox proportional-hazards models computed hazard ratios (HRs) for lifestyle characteristics associated with time to one of seven self-reported chronic diseases or death. Data were collected between 2003 and 2012 and analyzed between 2014 and 2016. RESULTS: Behaviors that most significantly affected future outcomes were low-fat diet, aerobic exercise, nonsmoking, and adequate sleep. A dose-response effect was seen between dietary fat intake and hypertension, obesity, diabetes, heart disease, and hypercholesterolemia. After dietary fat intake, aerobic exercise was the next most significant behavior associated with development of outcomes. Compared with sedentary participants, those who exercised 4 days per week were less likely to develop new-onset diabetes (HR=0.31, 95% CI=0.20, 0.48); heart disease (HR=0.46, 95% CI=0.27, 0.80); and hypercholesterolemia (HR=0.61, 95% CI=0.50, 0.74). Low-fat diet and adequate sleep were more significant than commonly promoted healthy behaviors, such as eating a daily breakfast. CONCLUSIONS: Modifiable lifestyle behaviors targeted in health promotion programs should be prioritized in an evidence-based manner. Top priorities for workplace health promotion should include low-fat diet, aerobic exercise, nonsmoking, and adequate sleep.

Relationship between physical inactivity and health characteristics among participants in an employee-wellness program.

OBJECTIVE: To characterize factors associated with physical inactivity among employees with access to workplace wellness program. METHODS: We examined data on physical inactivity, defined as exercise less than once a week, from the 2010 health risk assessment completed by employees at a major academic institution (N = 16,976). RESULTS: Among employees, 18% of individuals reported physical activity less than once a week. Individuals who were physically inactive as compared with physically active reported higher prevalence of cardiovascular diseases (adjusted odds ratio [AOR], 1.36 [1.23 to 1.51]), fair or poor health status (AOR, 3.52 [2.97 to 4.17]), and absenteeism from work (AOR, 1.59 [1.41 to 1.79]). Overall, physically inactive employees as compared with physically active employees reported more interest in health education programs. CONCLUSION: Future research is needed to address barriers to physical inactivity to improve employee wellness and potentially lower health utility costs.

Seven-year trends in employee health habits from a comprehensive workplace health promotion program at Vanderbilt University.

OBJECTIVE: To assess long-term changes in health risks for employees participating in Vanderbilt University's incentive-based worksite wellness program. METHODS: Descriptive longitudinal trends were examined for employees' health risk profiles for the period of 2003 to 2009. RESULTS: The majority of risk factors improved over time with the most consistent change occurring in physical activity. The proportion of employees exercising one or more days per week increased from 72.7% in 2003 to 83.4% in 2009. Positive annual, monotonic changes were also observed in percentage for nonsmokers and seat belt usage. Although the largest improvements occurred between the first two years, improvements continued without significant regression toward baseline. CONCLUSIONS: This 7-year evaluation, with high participation and large sample size, provides robust estimates of health improvements that can be achieved through a voluntary incentive-based wellness program.
