Social Medicine & Public Health: A Historical Overview

1. Social Medicine and Public Health: Historical Backgrounds

Social Medicine

Overview

Social medicine is a specialized field of medical knowledge that focuses on the social, cultural, and economic impact of medical phenomena. It covers a range of subjects, including epidemiology, the medical and health needs of society, the organization of health services, and disease prevention.

Goals:

• Understand how social and economic conditions impact health, disease, and the practice of medicine.
• Foster conditions in which this understanding can lead to a healthier society.

Today, the field of social medicine is most commonly addressed through public health efforts to understand what are known as social determinants of health.

History

Social medicine formally began in the early 19th century. The Industrial Revolution and the subsequent increase in poverty and disease among workers raised concerns about the effect of social processes on the health of the poor. Paul Farmer’s view is that modern medicine is focused at the molecular level, and there is a “gap” between social analysis and everyday clinical practices.

Public Health

Overview

Public health is the science and art of preventing disease, prolonging life, and promoting physical health and efficiency. The dimensions of health can encompass “a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity,” as defined by the United Nations’ World Health Organization (WHO).

Public Health Acts Through:

• Organized community efforts for environmental sanitation.
• Education of individuals in principles of personal hygiene.
• Organization of medical and nursing services for early diagnosis and preventative treatment of disease.
• Development of social machinery that ensures a standard of living adequate for the maintenance of health for every individual in the community.

Types of Populations Served

• As small as a handful of people.
• As large as all the inhabitants of several continents (e.g., in the case of a pandemic).

Main Goal

To improve health and quality of life through:

• Prevention and treatment of disease and other physical and mental health conditions.
• Surveillance of cases and health indicators.
• Promotion of healthy behaviors (e.g., handwashing, breastfeeding, vaccinations, and distribution of condoms to control the spread of STDs).

• Public health is concerned with threats to health based on population health analysis.
• Main concerns:
  • Health situation, health needs, and demands.
  • Health care system and health policy.

Evaluation of Health Services

• Legislation and health economy.
• Health insurance, informatics, and health management.

Main Tasks of Public Health

• Recognize health determinants (mainly social factors), their development, and their possible influences.
• Use this information in society and medical practice (health policy and administration).
• Help maintain and improve the health of the entire population.

5 Significant Roles of Public and Social Medicine

• Cognitive and Methodological: Social medicine deals with facts that can be defined, measured, and explained. It formulates and tests statistical hypotheses.
• Educational: People’s knowledge and information about healthy lifestyles and other health determinants are crucial for protecting and improving population health.
• Moral: Based on the fact that health is the most important human value, health care must be available to all people, and health professionals should be aware of ethical questions in medical practice and research.
• Organizational: Both serve as the theoretical base of health care administration, health management, and health policy strategy.
• Integrative: Public health considers all aspects of health and develops and evaluates health systems.

History

• From the beginnings of human civilization, it was recognized that polluted water and improper waste disposal spread communicable diseases.
• Early religions attempted to regulate behavior specifically related to health, from types of food eaten to regulating certain indulgent behaviors, such as drinking alcohol or sexual relations.
• Leaders were responsible for the health of their subjects to ensure social stability, prosperity, and maintain order.
• Romans understood that proper diversion of human waste was necessary for public health in urban areas.
• Ancient Chinese medical doctors developed the practice of variolation following a smallpox epidemic around 1000 BC.
• During the 14th-century Black Death in Europe, it was believed that removing bodies of the dead would prevent the spread of the bacterial infection. Burning parts of cities was more beneficial because it destroyed rodent infestations.
• The development of quarantine in the medieval period helped mitigate the effects of other infectious diseases.
• The 18th century saw rapid growth in voluntary hospitals in England.
• Vaccination became prevalent in the 1800s, following Edward Jenner’s pioneering work in treating smallpox.
• James Lind discovered the causes of scurvy among sailors and its mitigation by introducing fruit on lengthy voyages.
• In 1752, British physician Sir John Pringle published Observations on the Diseases of the Army in Camp and Garrison, advocating for adequate ventilation in military barracks and latrines for soldiers.
• With the Industrial Revolution, living standards among the working population worsened, with cramped and unsanitary urban conditions exacerbating the spread of disease.
• The first attempts at sanitary reform and the establishment of public health institutions were made in the 1840s.
• The Poor Law Commission reported in 1838 that “expenditures for preventative measures would ultimately be less than the cost of constantly engendered disease.” It recommended large-scale government engineering projects to alleviate conditions that allowed for the propagation of disease.
• The Public Health Act, passed in 1848, aimed to improve sanitation in towns and populous places in England and Wales by placing water supply, sewerage, drainage, cleansing, and paving under a single local body with the General Board of Health as a central authority.
• Vaccination for various diseases became compulsory in the United Kingdom in 1851. By 1871, legislation required a comprehensive registration system run by appointed vaccination officers.
