Chronic Diseases and NCD Prevention

Chronic Diseases

• Chronic diseases are permanent and cause residual disability.
• They result from non-reversible pathology.
• Patients require specialized rehabilitation training.
• Extensive follow-up, observation, and care are needed.
• Etiologic investigation of chronic non-communicable diseases (NCDs) faces challenges: unknown agents, multifactorial causes, long latency periods, indefinite onsets, and varying impacts of factors.

Prevention of NCDs

• Prevention of NCDs has received insufficient attention from policymakers and medical professionals.
• The time delay between cause and effect is significant.
• Primary prevention is possible for most NCDs due to: substantial population differences in NCD incidence and mortality, dynamic national trends in NCD rates, rapid changes in NCD risks among migrant populations, positive intervention trial results, and identification of modifiable risk factors.

Epidemiologic Transition

• This is a shift from acute infectious and nutritional deficiency diseases in underdeveloped regions to chronic NCDs in modern, developed societies.
• Demographic Changes: Decreasing infant mortality and fertility rates lead to population aging.
• Urbanization and Socioeconomic Transformation: Community relationships, lifestyles, moral beliefs, human mobility, education expansion, and female labor force participation are changing.
• Changes in Nutritional Patterns: Significant increases in food energy availability and consumption (rice, wheat, sugar, and fat). Vegetables and fruit intake remain low or slightly increased. This is linked to rising obesity.
• Other Factors: Smoking epidemic, alcohol consumption increase, sedentary lifestyles, and drug addiction.

Epidemiology of Cardiovascular Diseases (CVDs)

• CVDs account for 1/4th of global deaths; 49% in developed countries and 23% in developing countries.
• In 2023, approximately 60 million deaths worldwide were attributed to CVDs.
• CVDs were the leading cause (29%) of death globally in 2023.
• A complex mix of other diseases followed, with respiratory diseases (19%), lower respiratory infections (8.5%), COPD (4%), tuberculosis (4%), lung cancer (2%), and asthma/upper respiratory infections (0.5%) comprising a substantial portion of deaths. "Miscellaneous" causes accounted for 33% of the deaths.
• Developed countries saw approximately 21 million deaths from CVDs, while developing countries experienced roughly 39 million deaths in 2023.
• In regions like the Eastern Mediterranean (including Iraq), CVD morbidity, mortality, disability, human suffering, and economic costs are substantial.
• Demographic, socioeconomic, and behavioral shifts (urbanization, modern lifestyles, and aging) contribute to increased CVD problems.
• The CVD epidemic began in developed countries in the first half of the 20th century, peaked in the 1960s, and then declined. It continues to rise in developing countries.
• Variations in CVD incidence and mortality across countries and within countries are related to variations in major CVD risk factors.
