concept from an individual concern to a worldwide
social goal

1.Biomedical
Concept
• If onewas free from disease,the the
person was considered healthy
• Pathologically,an individual's body is
described as a machine,disease referred to
a fault in the machine and doctor is the
corrector of the machine
7.
Biomedical
Concept
Criticism:
This “biomedical concept”did not pay much attention on the
other determinants of health especially social,
environmental,
psychological and cultural. Hence, this was weak in
answering
the key health-related problems like accidents, malnutrition,
antisocial activities, etc.

•Human ecology isa part of the science of ecology. Human ecosystem includes
all dimensions of manmade environment—physical, chemical, biological and
psychological in addition to natural environment.
• According to the ecologists, health is viewed as a dynamic
equilibrium between man and environment, and disease
is viewed as an imbalance between the two. Human
ecological and cultural adaptations do determine not
only the occurrence of disease, but also food security and
population explosion.
• The ecological concept revolves around two issues:
(i) man and (ii) environment. Adaptation of man to natural
environment can result in prolonged life expectancies and
better quality of life even in the absence of modern health
amenities.

death;the level of wellness increases as one moves towards optimal
health
