The Physical Quality of Life Index (PQLI) as a measure of health and education

The Physical Quality of Life Index (PQLI) is a tool used to assess the social aspects of development, focusing on health and education rather than purely economic factors. Developed by David Morris in 1979, it provides a way to evaluate living standards across different countries.

Key components of the PQLI

• Infant mortality - Measures the number of deaths of infants under one year of age per 1,000 live births.
• Literacy rates - Assesses the percentage of the population able to read and write.
• Life expectancy - Evaluates the average number of years a person is expected to live.

Evaluation of the PQLI

• Comparative analysis - Allows for comparing trends across countries.
• Social focus - Emphasises social development, making it valuable for sociologists studying development as a social rather than economic issue.
• Data challenges - Collecting reliable data can be difficult.

Factors impacting health in less economically developed countries (LEDCs)

Health outcomes in less economically developed countries (LEDCs) are influenced by a range of social, economic, and educational factors. These challenges often result in poorer health compared to more economically developed countries (MEDCs).

Major barriers to health in LEDCs

• Poverty and diet - Limited financial resources lead to inadequate nutrition and poor public health conditions.
• Limited health care access - Universal free health care is uncommon, and most people must pay for medical services. There is also a shortage of doctors and nurses.
• Lack of health education - In many rural and traditional areas, there is little awareness of disease prevention or basic treatments.

Case study: HIV/AIDS in South Africa

• Insufficient education - Poor communities often lacked knowledge about how HIV is transmitted.
• Geographical barriers - Clinics were often located far away, sometimes requiring a full day's travel.
• Government reluctance - During the 1990s, the South African government hesitated to distribute anti-HIV drugs, partly due to doubts about whether HIV caused AIDS.

The role of transnational corporations (TNCs) and Western influences on health

Transnational corporations (TNCs) and Western practices have a significant impact on health in LEDCs, often with mixed consequences.

Negative impacts of TNCs and Western products

• Unsafe drugs - Some pharmaceutical companies sell drugs in LEDCs that are banned in Western countries due to safety concerns, or price life-saving medications beyond the reach of most people.
• Inappropriate product use - Western products like baby formula milk are heavily promoted in LEDCs, but without access to clean water, their use can lead to infant infections and deaths.
• Poor safety standards - TNCs operating in LEDCs often neglect environmental and health safety measures. A historical example is the Bhopal gas leak in 1984, where inadequate safety procedures led to a disaster.
• Drug pricing issues - In the case of HIV/AIDS in South Africa, TNCs initially refused to allow local companies to produce affordable versions of anti-HIV drugs, a practice banned by court rulings in 2001.

Theoretical perspectives on health inequalities in developing nations

Different sociological theories offer varying explanations and solutions for addressing health disparities between LEDCs and MEDCs.

Modernisation and functionalist views

• Superiority of Western medicine - These theorists argue that Western medical practices and technologies should be transferred to LEDCs to tackle issues like high infant mortality and low life expectancy.
• Rostow's approach (1971) - Suggests that high-tech medical solutions from developed nations can enhance health care provision in developing countries.

Marxist perspective

• Focus on basic health needs - Navarro (1976) contends that LEDCs should prioritise fundamental health measures over expensive Western technologies.
• Retaining medical professionals - Emphasises the need to encourage doctors and nurses to remain in their home countries rather than migrating to MEDCs for higher salaries.

Dependency theory

• Legacy of colonialism - Argues that health inequalities stem from historical exploitation, with colonialism introducing European diseases to regions like Africa, Asia, and the Americas.
• Agricultural shifts - Highlights how colonial powers replaced food crops with cash crops, leading to widespread malnutrition and health challenges.
