2. Target of public health approaches.
The shifting role of behaviour ( simple-complex)
Behavioural risk factors (itself- determinant-
consequent)
determinants of behaviour
Public health strategies to influence determinants of
behaviour
The interaction of socioeconomic status (SES),
environments, and behaviour
Denormalizing behaviour
Public health interventions and conclusion

3. control or cajole the health-
related behaviour of
individuals.
protect individuals from the
behaviour of others, and
mobilize the behaviour of
groups to influence health-
related social and physical
environments.

4. Simple or discrete
behaviours
( injuries-
infections)
complex behaviour
(chronic diseases)

5. the simple and discrete behavior can be
influenced directly by health education
targeted at individuals and groups.
 complex behavior required combination of
educational, organizational, economic,
and environmental interventions in
support of changes in both behaviour and
conditions of living.

6. Some behaviour clearly increases the risk of
developing disease.
Other behaviours correlate with and precede
better health, but their causal link is more
tenuous.
many behaviours are, in fact, contributing causes
(causal risk factors) of specific diseases.
the easiest examples of clear causal linkages are
those established for single action behaviours
such as ingesting a contaminated food

10.  intentionally most dramatic
(automobile, gun)
Unintentionally most
dramatic (toxic substances,
slippery surface)
Less dramatic , but no less
lethal (DI, smoking, alcohol,
inactivity)

11. behaviour remains a critical
mediator of the relationships
between environmental measures
and health outcomes.
improvement of the socioeconomic
condition is accompanied by a shift
in mortality
the three most important predictors
of infant mortality rates were
households sanitation, literacy rate,
and safe water.

12. Genes, via their influences on morphology
and physiology, create a framework within
which the environment acts to shape the
behavior of an individual.
Genes also create the scaffold for
learning, memory, and cognition that can
be used in shaping behavior.
The environment can affect morphological
and physiological development; in turn
behavior develops as a result of that
mechanism.

Enabling factors
Reinforcing factors

15. 1- Educational strategies inform
and educate the public about
issues of concern such as :
the dangers of drug misuse,
the benefits of automobile
restraints,
the relationship of maternal
alcohol consumption to foetal
alcohol syndrome.
…..

16. 2- Automatic-protective strategies are directed
at controlling environmental variables, that
minimize the need for individual decisions in
structuring each behaviour, such as:
 milk pasteurization,
 fluoridation,
 infant immunizations, and
the burning of marijuana crops.
……………… .

17. 3- Coercive strategies employ legal and other
formal sanctions to control individual
behaviour, such as:
 required immunizations for school entry,
mandatory tuberculosis testing of hospital
employees,
 compulsory use of automobile restraints.
arrests for drug possession or use.
…………

18. Population behavioural and educational
diagnoses enable public health to intervene
strategically on the behaviour of populations.
 But health problems have other determinants
in the environment and in genetics.
Behaviour also can play a role in influencing
those determinants.

19. Through Human Genome Project genetics
information became available to individuals.
 The first assumption remains to be supported
by true evidence of effectiveness
(susceptibility to illness-sensitivity to drug)
The second assumption, that having such
information would motivate more concerted
effort to change one's behaviour

20. the limited influence of the genes so far
implicated in specific mortality or morbidity
outcomes, and their interactions with the
environment .
the ethics of offering such information to the
individual with anything more than a
cautionary note of possible relevance to their
reproductive decisions or their behavioural
choices

21. The threshold effects are
sometimes found beyond
income or other SES
indicators.
The gradient adheres
whether the SES measure
is education, income,
occupational status, or
place of residence

22. SES as a predisposing determinant of
behaviour
SES as an enabling determinant of behaviour
The educational enabling influence of SES on
behaviour
The cultural-environmental predisposing
influence of SES
SES as a reinforcing determinant of
behaviour
The ‘status identity factor’ and social norms

23. ‘denormalization’ of smoking behaviour in
public places. legal restrictions- social norms

The combination of new smoke-free or ‘clean
air’ ordinances and by-laws with mass media
emphasizing the carcinogenic properties of
second-hand smoke and the rights of non-
smokers

24. These differences cannot be attributed solely
to biological determinants related to sexual
differentiation
The social construct of gender, as opposed to
the biological categories of sex, was
conceptualized to refer to cultural and social
conventions, roles and behaviours assigned
to men and women
The gender interactions with SES and health
have been variously attributed to differential
occupational experiences

25. The dynamic relationships among
the specific measures creates a
complex system of social,
economic, cultural, and
behavioural factors.
The system interwoven with
disease risk factors and health
status, and influenced by the
healthcare and physical
environments.

26. public health programmes shuold plan for behaviour
change in three categories of determinants:

27.  direct communications to influence the
knowledge, attitudes beliefs, and perceptions of
the population concerning the behaviour-health
relationship;
indirect communications through social
organizations, parents, peers, employers, and
others who control rewards and approval that
would reinforce behaviour.
legal, engineering, financial, organizational levers
and resource development that would enable or
prohibit the behaviour.

28. Behaviour is an inescapable link in the chain of
causation between most environmental and genetic
determinants and the health outcomes in which they are
implicated.
The social environment presents a further complexity in
the mediating and moderating of behaviour and
environment in their determination of population health.
The individuals are acting upon, and in reaction to, each
other as their health outcomes are being shaped by
their actions.
