Study Notes
Global Health Challenges
- Global health challenges are complex and interconnected, impacting population health and healthcare delivery.
- Population size is determined by factors like fertility, mortality, and migration.
- Health service planning must consider demographic factors to effectively meet the needs of different population segments, both present and future.
Demography
- Demography is the study of human populations, including size, composition, spatial distribution, and changes over time.
- Population change occurs through the interplay of fertility, mortality, and migration.
- Fertility refers to the number of births.
- Mortality refers to the number of deaths.
- Migration refers to the movement of people into or out of a specific area.
Population Growth Trends
- World population has significantly increased since 1700, with projections showing continued growth in the future, albeit with varied scenarios.
- Global fertility rates have decreased considerably in the last 50 years, currently at about 2.5 babies per woman.
- Population growth is more prevalent in developing countries compared to developed countries.
Migration
- International migration involves about 258 million people globally.
- Most migrants originate from developing countries and move to industrialized nations.
- Refugees and asylum seekers numbered approximately 25.9 million in 2016.
- War and conflict, such as the Syrian war, often cause large-scale population displacement.
- The Afghanistan conflict of 2021 led to a 50% increase in displacement.
- Russia's invasion of Ukraine resulted in 6 million Ukrainians seeking refuge.
Urbanization
- Urban areas are experiencing population growth, with 55% of the world's population residing in cities.
- Projections indicate this figure will reach 68% by 2050.
- Factors driving urbanization include economic development, better job opportunities, and improved public services.
Negative Impacts of Urbanization
- Overcrowding in urban areas can lead to poor sanitation and inadequate housing.
- Urban planning inadequacies are common, impacting transport, food systems, contributing to air pollution, and causing traffic injury.
- Mental health issues are increasing, and urban health risks disproportionately affect specific social groups.
Population Aging
- Population aging is happening more rapidly than in the past.
- By 2050, the proportion of the global population aged 60+ is projected to nearly double from 12% to 22%.
- Very elderly individuals (85+) constitute a significant portion of the aging population.
Age Dependency Ratio
- Age dependency ratio (total) is the ratio of dependents (younger than 15 or older than 64) to the working-age population (15-64).
- The ratio is calculated as the proportion of dependents per 100 working-age people.
- Age dependency ratios are expected to increase in the coming years.
Major Global Health Threats (2019 Predictions)
- Ten predicted major global health threats in 2019 included non-communicable diseases, global influenza, antimicrobial resistance, fragile societies, and outbreaks of infectious diseases (like Ebola).
Health Impacts of Climate Change
- Climate change directly influences health, leading to extreme weather events, waterborne diseases, infectious disease patterns, and malnutrition, among other consequences.
- Increased burden of non-communicable diseases and heat stress occur.
- Factors like migration and displacement lead to increased strain on health services and food shortages, further exacerbating health issues.
Role of Health Professionals and Public Health Policy
- Health professionals have a critical role in addressing climate change.
- Promoting sustainable healthcare is crucial to reducing healthcare-related carbon emissions, as healthcare contributes to approximately 4-5% of global greenhouse gas emissions.
