Introduction
• Increasing life expectancy is a hallmark of progress but can become counterproductive if additional years are characterized by illness and disability.
• The objective is to ensure that added years to life are healthy, productive, and fulfilling, narrowing the gap between lifespan (total years lived) and healthspan (years lived in good health).
Historical Progress in Life Expectancy
• Global Increase in Life Expectancy: Advances in water and sanitation, nutrition, and medical technologies significantly reduced mortality from infectious diseases. Societal developments such as education, economic growth, and women’s empowerment contributed to healthier populations. Decolonization allowed nations to focus on developmental goals, improving public health infrastructure.

• Challenges of Rising Lifespan: Survivors of infectious diseases often faced long-term disabilities, undermining quality of life. Chronic health conditions due to aging required prolonged medical care, increasing dependency and financial burdens.

The Shift to Non-Communicable Diseases (NCDs)
• Dominant Diseases: Cardiovascular diseases, diabetes, cancers, and chronic respiratory illnesses became the leading causes of death and disability. Overweight and obesity rose alarmingly, further compounding the burden of NCDs.

• Overweight and obesity rose alarmingly, further compounding the burden of NCDs.
• Lifestyle and Commercial Drivers: The global consumption of tobacco, ultra-processed foods, and sugar-sweetened beverages led to widespread health deterioration. Sedentary lifestyles due to automobiles, television, and the internet reduced physical activity levels.

• Sedentary lifestyles due to automobiles, television, and the internet reduced physical activity levels.
• Social and Environmental Challenges: Rising mental health issues, especially among youth, were linked to emotional disconnection in a digitally hyperconnected world. Road accidents, suicide, and homicidal violence further contributed to the health burden. Environmental factors like air pollution and climate change introduced new health risks, including respiratory diseases and vector-borne illnesses.

21st Century Trends: Life Expectancy vs. Healthy Life Expectancy
Global Trends
• Gap Analysis: The study by Garmany and Terzic (2024) reported a global mean gap of 9.6 years between life expectancy and healthy life expectancy from 2000 to 2019. Gender Disparity: The gap was 2.4 years wider in women compared to men, largely due to higher longevity in women paired with prolonged health issues.

• Gender Disparity: The gap was 2.4 years wider in women compared to men, largely due to higher longevity in women paired with prolonged health issues.
• Country-Specific Insights: Developed countries like the USA (12.4 years) and UK (11.3 years) displayed the largest gaps. Despite economic progress, unhealthy lifestyles and aging populations drove this disparity. Low-income countries like Lesotho showed narrower gaps but required simultaneous improvements in both lifespan and healthspan.

India’s Performance
• Statistics (2000-2019): Life expectancy increased at 0.43 years per year, while healthy life expectancy rose at 0.37 years per year. This widened the gap to 10.49 years by 2022: 9.22 years for men and 11.77 years for women.
