Preventing chronic diseases: how many lives can we save?

Area of Science:

• Global Health
• Epidemiology
• Preventive Medicine

Background:

• Chronic diseases, including heart disease, stroke, and cancer, are projected to cause 35 million deaths in 2005.
• A significant majority (80%) of these deaths will occur in low- and middle-income countries, with higher rates among adults aged 30-69.
• Death rates from these preventable diseases are notably higher in low- and middle-income countries compared to high-income nations.

Purpose of the Study:

• To propose a new global goal for reducing mortality from chronic diseases.
• To focus prevention and control efforts on international health concerns.
• To estimate the impact of a 2% annual reduction in chronic disease death rates.

Main Methods:

• Utilizing worldwide projections of deaths by cause for 2005 and 2015.
• Analyzing data for the global population, selected countries, and World Bank income groups.
• Calculating potential averted deaths and life-years gained from the proposed goal.

Main Results:

• A 2% annual reduction in chronic disease death rates could avert 36 million deaths by 2015.
• This goal is projected to result in approximately 500 million years of life gained between 2006 and 2015.
• The majority of averted deaths and life-years gained are expected in low- and middle-income countries, with nearly half benefiting individuals under 70.

Conclusions:

• Implementing a global goal to reduce chronic disease death rates by 2% annually is feasible and impactful.
• This strategy offers substantial benefits for international health, particularly in low- and middle-income countries.
• The proposed goal addresses a critical global health challenge with significant potential to save lives and improve longevity.
