    Study Notes

    Populations, Planning and Current Global Health Challenges

    • Global population growth is increasing rapidly
    • The interplay of fertility, mortality, and migration affects population size and composition
    • Health service planning needs to consider demographic factors for successful implementation
    • Global health challenges include climate change, non-communicable diseases, and antimicrobial resistance
    • Healthcare contributes to the climate crisis, representing 4-5% of global greenhouse gas emissions
    • The role of healthcare professionals is crucial in addressing climate change

    Definition and Use of Demography

    • Demography is the study of human populations, including size, composition, spatial distribution, and changes
    • Population change processes include fertility, mortality, and migration
    • These processes determine population growth or decline

    World Population

    • World population has increased significantly since 1700
    • Projections show varying growth scenarios for the future

    Global Fertility Rate

    • Global fertility has decreased significantly over the past 50 years
    • Current fertility rate is 2.5 babies per woman globally

    Global Difference in Population Growth

    • Population growth is concentrated in developing countries
    • Developed countries have comparatively slower population growth

    Population Change Processes

    • Population change is determined by inputs (births, immigration) and outputs (deaths, emigration)
    • Natural increase, total population, and migration are crucial concepts in understanding population dynamics

    Births

    • Historically, birth rates were higher in Europe
    • Current birth rates in many European countries are below 2 children per woman

    Migration

    • There are approximately 258 million international migrants globally
    • Most international migrants originate from developing countries
    • Refugees and asylum seekers totaled 25.9 million in 2016

    War and Migration

    • Wars, such as in Syria and Afghanistan, have caused significant population displacement, with a significant portion of displaced people being children
    • The 2022 Russian invasion of Ukraine caused the displacement of approximately 6 million Ukrainians

    Urbanization and Migration

    • Urban areas are experiencing increased population growth
    • Economic development, job opportunities, and public services drive urban migration
    • Urbanization leads to overcrowding, inadequate infrastructure, sanitation challenges, and traffic issues

    Negative Public Health Impacts of Urbanization

    • Overcrowding in slums and unplanned urban areas
    • Poor sanitation and lack of adequate transport and food systems
    • Air pollution and traffic injuries
    • Increased rates of mental health issues
    • Unequal distribution of urban health risks across social groups

    Deaths - People are now living longer

    • The pace of population ageing is accelerating
    • The proportion of the population over 60 will nearly double by 2050 from 12% to 22%
    • The number of very elderly people (over 85 years old) is an important factor to consider in an aging population

    Age Dependency Ratio

    • Age dependency ratio is the ratio of dependents (younger than 15 and older than 64) to the working-age population
    • Those under 15 and over 65 have the greatest needs for health services
    • Dependency ratios are projected to rise in the coming years

    Key Global Health Challenges - 2019 Predictions

    • Air pollution and climate change were identified among the major global health threats in 2019 projections

    Major Global Health Challenges

    • Various global health challenges have been documented.

    Projections for Bahrain's Aging Population

    • Bahrain's aging population is projected to increase in the coming decades, according to projections from 2019-2030.

    MOH Initiatives for Elderly Care in Bahrain

    • Bahrain's Ministry of Health (MOH) initiated mobile health units for elderly care home visits starting in 2008

    Role of Health Professionals and Public Health Policy

    • Health professionals and policymakers must address the health threat of climate change tangibly
    • Sustainable healthcare activities in healthcare systems are responsible for a significant portion (4-5%) of global greenhouse gas emissions
