Health programs aim to improve the health and wellbeing of people by preventing disease and promoting healthy lifestyles. These efforts can take place at individual, community, and population levels. They can also be targeted at specific health conditions and may include strategies for improving access to care and services (e.g., reducing costs or improving insurance coverage) and making sure that health care providers are aware of and follow guidelines for treating patients.
Many communities have implemented their own health improvement initiatives, and a large number of community-based programs are now available to address health-related needs. However, it is difficult to determine whether a particular program has improved health outcomes. Most studies of these initiatives rely on pre-post evaluation designs without a comparison group, and most do not use statistical techniques to estimate the association between program implementation and health outcomes at the county level. This article uses a controlled design and regression techniques to estimate the impact of one such initiative, a comprehensive workplace wellness program implemented by Capital Metro Transportation Authority in Austin, Texas. The results indicate that the program was associated with modest improvements in self-reported health outcomes and behaviors, but no detectable effects on clinical measures of health or on medical and prescription drug spending and utilization or employment outcomes.
The program was designed to improve workplace morale, reduce health care costs and absenteeism, and promote healthier food choices and physical activity. In addition to providing modest financial incentives for employees who participated, the program provided education and training sessions. It also included support groups and a program website for participants. The study finds that the program had no detectable effects on all other prespecified outcomes, including a 0.15 percentage point decrease in the proportion of the county population reporting fair or poor health and a small increase in rates of smoking and obesity. Program counties tended to have younger residents and higher rates of poverty and unemployment than nonprogram counties, which could explain these findings.
Health programs can be successful only if they are grounded in the local context of the people to whom they are offered. For example, several COVID-19 vaccination efforts failed because they did not offer vaccines for all ages in locations where multigenerational families lived together. In addition, any effort to improve health should focus on addressing underlying causes of health disparities. This includes recognizing the prevalence of structural racism and addressing its impacts, which are still felt by blacks and indigenous peoples. In the United States, these underlying factors have long contributed to the unequal distribution of resources and power, which are the root cause of most health inequities. In the future, addressing these inequities will require all sectors of society to work together toward the goal of universal health coverage and better, more integrated primary health care. The full range of health services, from prevention and promotion to treatment, rehabilitation, and palliative care, should be made accessible as close as possible to the people for whom it is intended.
