CHANGING CONCEPTS in PUBLIC HEALTH
10. 1. Disease control phase (1880 - 1920)
• Public health during the 19th century was largely a
matter of Sanitary legislation and Sanitary reforms
aimed at the control of man’s Physical environment,
e.g., water supply, sewage disposal, etc.
• Clearly these measures were not aimed at the control
of any specific disease
• However, these measures vastly improved the health
of the people due to disease and death control.
11. At the beginning of the 20th century, a new
concept, the concept of "Health Promotion"
began to take shape.
2. Health promotional phase (1920 - 1960)
12. • Mother and child health services,
• School health services,
• Industrial health services,
• Mental health and
• Rehabilitation services.

15. • Is an attempt to bring about a
social and economic
transformation of village life
through the efforts of the people
themselves
• Promote village development
• Active participation of whole
community
b) Community development programme, 1952
16. • With the advances in preventive medicine
and practice of public health, the pattern
of disease began to change in the
developed world.
• Many of the acute illness problems have
been brought under control.
3. Social engineering phase (1960 - 1980)
21. • A new concept, the concept of "risk factors" as
determinants of these diseases came into
existence.
• The consequences of these diseases, unlike the
swift death brought by the acute infectious
diseases, was to place a chronic burden on the
society that created them. These problems brought
new challenges to public health which needed
reorientation more towards social objectives.
22. Public health entered a new phase in
the 1960s, described as the "social
engineering" phase
23. • Social and behavioural aspects of
disease and health .
• Public health moved into the
preventive and rehabilitative aspects of
chronic diseases and behavioural
problems.

26. 4. Health for All (1981 - 2000)
• Most people in the developed countries, and the elite of
the developing countries, enjoy all the determinants of
good health - adequate income, nutrition, education,
sanitation, safe drinking water and comprehensive
health care.
• In contrast, only 10 to 20% of the population in
developing countries enjoy ready access to health
services of any kind.
27. • Death claims 60-250 of every 1000 live
births within the first year of life
• Life expectancy is 30% lower than in the
developed countries .
28. “Large no. of the worlds
peoples, perhaps more than
half, have no access to
health care at all, and for
many of the rest, the care
they receive does not
answer the problems they
have”.
29. In 1981 WHO pledged
“Health For All” by 2000 to
bridge the gap between
developing and developed
countries.
