Editorial 1 : Prescribe preventive medicine for a healthy India

Context

With India dealing with a rising number of non-communicable diseases, it's important to understand that prevention is better than cure.

Introduction

India is on the brink of economic success, aiming to become a $5 trillion economy and a global leader. However, a “silent epidemic” of non-communicable diseases (NCDs) is threatening our progress. NCDs are now the top cause of death in the country, making up about two-thirds of all deaths. To ensure a healthy and prosperous future, India must quickly adopt a preventive health-care approach — one that focuses on preventing problems before they arise.

The rising tide of NCDs, their economic toll

• Shift from Communicable Diseases to NCDs
  • Over the last few decades, India has undergone an epidemiological transition.
  • Communicable diseases (such as infections) have been largely brought under control.
  • However, NCDs (chronic conditions) like heart disease, diabetes, cancers, chronic lung diseases, and stroke have become more prevalent.
• Impact of NCDs on India
  • Annual Mortality: Approximately 5-6 million Indians die each year from NCDs.
  • Young Population Affected: NCDs are increasingly affecting younger Indians, including those in the working-age population.
  • Economic Impact:
    • NCDs are having a significant economic cost due to loss of productivity and reduced workforce participation.
    • Cost to GDP: Estimated loss to India’s GDP is between 5%-10%.
    • A study by the World Economic Forum and Harvard School of Public Health projected a loss of $3.5 trillion–$4 trillion to the Indian economy between 2012 and 2030.

Key Stats and Trends

Health and Economic Implications of NCDs

• Workforce Impact: India’s youthful demographic dividend is threatened as the working-age population is increasingly affected by NCDs.
  • Rising cases of heart disease, diabetes, and other NCDs among individuals aged 30 to 40 pose a significant challenge.
• Economic Strain: Beyond the human toll, NCDs are estimated to cost India 5%-10% of its GDP.
  • Projected Economic Loss: $3.5 trillion to $4 trillion (2012-2030).

The Preventability of NCDs

• Key Causes of NCDs: Lifestyle Factors: Sedentary lifestyles, unhealthy diets, tobacco and alcohol use.
  • Environmental Factors: Air pollution.
  • Genetic Predisposition: Family history of certain conditions.
• Prevention Strategies:
  • 80% of Cases Preventable:
    • 80% of premature heart disease, stroke, and diabetes cases can be prevented by modifying lifestyle factors.
  • Addressing Obesity:
    • Around 22%-23% of adults are overweight.
    • Addressing obesity through lifestyle changes is crucial for reducing NCD risks.
• Key Lifestyle Modifications:
  • Exercise: At least 30 minutes of moderate exercise daily (e.g., walking, yoga, sports).
  • Diet: A healthy diet with plenty of fruits, vegetables, and proteins while limiting sugar, salt, and unhealthy fats.
  • Pollution Control: Air pollution is a major factor in respiratory diseases like COPD, lung cancer, and heart attacks. Pollution control should be integrated into preventive health measures.

Role of Regular Health Screenings

• Importance of Early Detection: Regular screenings, starting at age 40 (or earlier for those with a family history), can save lives.
  • Early detection leads to timely intervention, preventing severe conditions like stroke, cancer, or heart disease.
• Types of Screenings: Blood Pressure Monitoring: Preventing strokes by controlling blood pressure.
  • Cancer Screenings:
    • Mammograms for early breast cancer detection.
    • HPV tests for early detection of cervical cancer.
    • Colon cancer screenings to detect precancerous polyps.

The Role of Digital Health Technology in Preventive Care

• Digital Health Technology as a Game Changer
  • Smartphone Apps and Wearables are revolutionizing healthcare delivery.
  • India, with over 750 million smartphone users, has the potential to provide health advice, reminders, and risk assessments directly to individuals' hands.
  • Wearable devices and health trackers allow users to monitor their health in real-time, helping track vital statistics like heart rate, sleep patterns, and physical activity.

• Artificial Intelligence (AI) in Predictive Health Modelling
  • AI algorithms can analyze large datasets to predict health risks with high accuracy, offering valuable insights for preventive care.
  • Health Risk Score: AI tools can create a personalized health risk score, predicting the likelihood of conditions such as heart attacks or diabetes within the next decade.
  • Early Diagnostics:
    • Machine learning models can scan X-rays or CT scans to detect conditions like lung nodules or fatty liver at early stages, which may be missed by human doctors.
    • Pre-emptive action: AI enables early intervention by identifying potential health issues before they become critical.

Key Benefits of Digital Health and AI Integration

Ensuring Patient-Centric and Compassionate Care

• Human-Centered Approach: While AI can revolutionize preventive medicine, it is essential that it remains humane, compassionate, and patient-centric.
  • Ethical Use of AI: Digital health and AI should be used responsibly to ensure they support, rather than replace, human judgment and empathy in healthcare.
• The Future of Preventive Care: Digital health technologies and AI, when used together, can make preventive care more proactive, precise, and accessible, helping to reduce the burden of NCDs across India.

Fostering a ‘preventive mindset’

1. Preventive Medicine: A Mindset, Not Just a Service

• Health-First Mindset: Preventive medicine is a mindset that should be adopted by individuals, corporates, communities, and governments.
• Individual Responsibility:
  • Become the champion of your own health.
  • Schedule that postponed check-up and make small changes like taking the stairs or reducing sugar intake.

2. Corporate Role in Wellness

• Workplace Wellness: Corporates should invest in employee wellness programs, including annual health checks, in-house counselors, and fitness sessions.

3. Shift in Health-Care Models

• Preventive Care Focus: Health-care providers must shift from a reactive cure model to a preventive care model.

4. Government Initiatives

• Key Government Programs:
  • National Programme for Prevention and Control of NCDs and Health and Wellness Centres focus on screening and prevention.
  • Public Policies:
    • Urban planning should include green spaces.
    • Education should include health and nutrition.
    • Food industry regulations should promote lower salt and sugar.

Conclusion

Over the years, as I’ve worked to make preventive care more accessible and effective, I’ve seen countless lives changed by catching a disease early or managing a risk factor in time. Every person has the ability to make choices that protect their health. When these choices are made by 1.4 billion Indians, they can shape the health and happiness of our nation and help us achieve our economic goals.
