Protecting the health of healers: Knowledge-to-practice gap among healthcare professionals

ABSTRACT

Medical professionals are well educated regarding the causes and strategies to prevent lifestyle diseases. Paradoxically, many within this population suffer from these same conditions, underscoring a substantial knowledge-to-practice gap. Global research indicates that physicians, despite their expertise, encounter increasing incidences of lifestyle-related disorders, frequently attributed to occupational stress, prolonged working hours, inadequate sleep, and irregular food patterns.

Background

The swift global surge in lifestyle diseases, such as diabetes, cardiovascular ailments, obesity, and mental health disorders, presents a significant public health challenge. These disorders predominantly stem from modifiable behaviours such as unhealthy food habits, limited physical activity, tobacco consumption, and various kinds of stress – cultural, social, economic, and socio-political. Despite advancements in medical knowledge, a concerning mismatch persists between theoretical understanding and practical application, especially among healthcare professionals, who are anticipated to serve as exemplars of healthy living. This advocacy paper emphasizes the necessity of bridging the knowledge-to-practice gap among physicians and presents solutions to enhance lifestyle health outcomes for healthcare providers and the communities they serve.

The Escalating Burden of Lifestyle Diseases

Noncommunicable diseases (NCDs) are the major contributors to worldwide morbidity and mortality, accounting for over 70% of annual fatalities. Globally, about 537 million persons are afflicted with diabetes, whereas cardiovascular illnesses account for over 18 million fatalities annually.[1] India, one of the major contributors to this burden, has over 77 million people living with diabetes, and heart disease remains the leading cause of death. Diseases like diabetes actually cause multi-organ involvement, thus increasing the patient morbidity manifold. These disorders significantly diminish quality of life and impose substantial pressure on healthcare systems and economies. Urbanization, sedentary habits, the intake of processed foods rich in simple carbohydrates and trans fats, tobacco and alcohol consumption, and persistent physical, mental, and emotional stress are primary factors contributing to this epidemic. The resultant health issues encompass obesity, hypertension, abnormal lipid profiles, and mental disorders including depression and anxiety, which frequently coexist and exacerbate one another’s impacts. The social and economic ramifications are severe, encompassing heightened healthcare expenditures and diminished workforce productivity.[2]

Healthcare Professionals: A Paradox of Knowledge and Practice

Medical professionals are well educated regarding the causes and strategies to prevent lifestyle diseases. Paradoxically, many within this population suffer from these same conditions, underscoring a substantial knowledge-to-practice gap. Global research indicates that physicians, despite their expertise, encounter increasing incidences of lifestyle-related disorders, frequently attributed to occupational stress, prolonged working hours, inadequate sleep, and irregular food patterns. For example, a recently conducted systematic review on alcohol use among physicians across different countries worldwide identified heterogeneity in problematic alcohol use: (0% to 34% with AUDIT; 9% to 35% with AUDIT-C; 4% to 22% with CAGE); in addition, the prevalence of reported problematic alcohol use was found to be increasing over time – 16.3% in 2006 to 2010 to 26.8% in 2017 to 2020.[3] A recent single-centre study from Gujarat, India, reported that approximately 20% of doctors in India are obese, over 50% are diabetic or prediabetic, and a significant proportion suffer from hypertension and stress-related disorders.[4] Several other studies among different cadres of health care workers report similar findings.

This paradox is caused by a number of things. First, medical school programs do not always focus enough on lifestyle medicine, rendering the students and practitioners underprepared for primary prevention. A study conducted on medical students of different countries reported that training or courses in preventive counselling are required.[5] Although the majority of medical students maintained favourable attitudes toward preventive counselling, they were lacking in confidence, efficient approaches, and skills to practice preventive counselling. Second, medical school teaching focusses primarily on the disease pathophysiology and pharmacological aspects of disease treatment while ignoring the broader social, economic, cultural, and even political determinants of disease that require a holistic and more comprehensive approach. Furthermore, the capacity of healthcare personnel to adopt healthy behaviours is impeded by systemic barriers, including heavy workloads, high stress, and limited time for self-care.

A careful look reveals that this paradox is also shaped by the often-overlooked influence of the hidden curriculum – the set of unspoken values, behaviours, and cultural norms transmitted informally within medical institutions. Medical students and young doctors often internalise unhealthy patterns related to diet, sleep, stress management, and substance use simply by observing peers, seniors, and workplace culture. Over time, these tacit messages become more powerful than formal teachings on lifestyle medicine. The hidden curriculum normalises behaviours such as skipping meals, eating calorie-dense hospital canteen food at odd hours, glorifying sleep deprivation, sidelining physical activity, and viewing alcohol or nicotine as acceptable coping mechanisms. Peer pressure further reinforces these behaviours, especially in environments where overwork is valorised and self-care is perceived as indulgent or unprofessional.

Implications of the Gap on Healthcare Delivery

The unfavourable lifestyle habits of healthcare professionals might adversely impact patient care in various ways. It is a question of the old adage: ‘Example is better than precept.” Physicians who grapple with lifestyle diseases at times have less credibility in recommending behavioural modifications to patients, therefore decreasing the impact of counselling. Moreover, burnout and chronic disease among medical personnel lead to absenteeism, diminished work efficiency, and escalated healthcare expenditures. This cycle makes it harder to stop the spread of NCDs across communities. Initiatives aimed at closing the knowledge–practice gap among physicians can have a multiplicative impact. Enhancing the well-being of healthcare professionals will elevate their counselling abilities and role modelling, thereby magnifying public health benefits.

Recommendations for Bridging the Knowledge–Practice Gap

1. Enhanced medical education in lifestyle medicine: Medical education in the twentieth century was shaped profoundly by the Flexner Report, which emphasised molecular biology and pathologic mechanisms while giving little attention to the socio-ecological determinants of health.[6] Yet the realities of the 21st century – rising chronic diseases, deepening health disparities, and a rapidly evolving healthcare system – strongly indicate that health and illness can no longer be understood solely through a biomedical framework; they must be situated within a wider public health context. However, medical curricula have been slower to acknowledge the complex, interconnected social and ecological forces that shape health, well-being, and disease. Medical training, especially undergraduate medical education in our country, needs huge reforms. While maintaining an individual and patient-centric, clinical approach (even this has been lacking of late due to the advent of investigation-based medicine), undergraduate medical education must focus on the social determinants of health and the concept of health as laid down by the World Health Organisation. Medical training should integrate comprehensive modules on nutrition, physical activity, stress management, and behavioural counselling techniques. Such education must emphasise application in personal and professional contexts.[5] There are data to suggest that preventive medicine residency programs are underutilised in medical education and training. Such residency programmes can be a vital resource in fostering the importance of public health and preventive medicine in medical education.

2. Institutional wellness programs: Healthcare institutions must implement wellness initiatives targeting doctors and staff, providing structured opportunities for fitness, mental health support, nutritional advice, and stress reduction. Policies enabling flexible work schedules and rest periods are crucial. Institutional programmes can be secondary-level interventions (managing stress in individuals), or these can be primary-level (eliminating causes of stress). Some institutional programmes that have been implemented include mindfulness-based practices, meditation, yoga and acupuncture, promotion of a positive mindset (gratitude journaling, choirs, coaching), and organisational interventions like workload reduction, job crafting, and peer networking. A recent systematic review assessing the impact of workplace interventions on well-being and of healthcare professionals found that workplace interventions benefitted healthcare workers by increasing well-being, engagement and resilience, and reducing burnout

3. Systemic reforms to reduce occupational stress: Workplace burnout is common among healthcare professionals. Addressing long working hours, high patient loads, and administrative burdens is necessary to prevent burnout and promote healthier lifestyles among medical professionals. Several strategies can be used to cope with burnout. These include, but are not limited to, nurturing family and social relationships, building supportive connections with colleagues, redefining work-related attitudes, initiating self-care practices like exercise, creative expression, healthy diet and sleep, and seeking counselling when needed

4. Role modelling and advocacy: Medical professionals should be encouraged and supported to serve as role models for healthy living, enhancing their credibility with patients. It has been shown that medical role models can play a vital role in helping medical trainees mature professionally and can motivate medical students to keep their focus, stay determined, and have perseverance in work. It has also been observed that physician counselling regarding lifestyle modifications is closely linked to one’s own health practices; therefore, addressing healthcare providers’ own health behaviours is key to substantially increasing health promotion counselling in general practice. Peer support networks and mentorship can foster sustained behavioural changes

5. Research and monitoring: There are multiple studies that have looked into the prevalence of lifestyle disorders among healthcare workers.[2] Ongoing studies to monitor lifestyle disease prevalence among healthcare workers and evaluate interventions will inform policy and practice improvements.[7] However, despite the availability of several such studies, there remains a pressing need to generate more robust data, identify the determinants behind the poor adoption of lifestyle-modifying behaviours among healthcare workers, and develop a constructive, context-specific framework that incorporates these factors and can be effectively implemented at the grassroots level.

Conclusion

The rising burden of lifestyle diseases represents one of the most pressing and urgent public health challenges of our century. These conditions – shaped by complex interactions of behaviour, environment, and systemic factors – not only strain healthcare systems but also silently erode the well-being and productivity of societies. In this context, the widening knowledge-to-practice gap among healthcare professionals becomes particularly troubling. Doctors, nurses, and allied health workers stand at the intersection of caregiving and public trust: They are expected not only to treat disease but also to embody the principles of prevention and healthy living. Yet, despite possessing deep medical knowledge, many struggle to translate this understanding into sustained personal health practices. Bridging this gap requires more than individual motivation; it demands a coordinated transformation in the environments in which healthcare workers live and work. Comprehensive educational initiatives must revisit how lifestyle medicine, behaviour change, and self-care are taught –moving beyond theoretical instruction to continuous skill-building and reflective practice. Policy changes that prioritise occupational health, ensure mandatory rest periods, and integrate wellness into hospital accreditation standards can significantly shift the culture of healthcare institutions. Healthcare professionals must reclaim their role as advocates – not only for their patients but also for themselves. A healthier medical workforce becomes a powerful catalyst for healthier communities.
