traditional health promotion
knowledge = attitudes = behaviour = practice
health public policy
legal, fiscal, regulatory (HIA, European directive
community development
radical individuals setting their own agenda
how many levels of prevention are there
4
primordial prevention
prevention of factors that prevent the emergence of lifestyles, behaviours, exposure patterns which contribute to increased risk of disease
primary prevention
actions to prevent onset of disease limit exposure to risk factors individual behaviour change actions in community health promotion - health education and prescriptive diets specific protection - vaccination
secondary prevention
halt progression when illness is already established
early detection
effective treatment
special consideration of asymptomatic individuals
tertiary prevention
rehabilitation of people with established disease to minimise residual disability and complications
QOL action even if disease cannot be cured
high risk prevention
identifying those in special need
then controlling exposure or provide protection against exposure - vaccination
population prevention
recognition that occurrence of common conditions reflect behaviour and circumstances of society as a whole
describe the prevention paradox
many people exposed to a small risk may generate more disease than the few exposed to a small risk
when many people receive a small benefit the total benefit may be large
individual inconvenience may be high to the many when benefit may inly be to a few
strength of high risk approach
effective - high motivation efficient - cost effective benefit:risk ratio is favourable appropriate to the individual easy to evaluate
weakness of high risk approach
palliative and temporary - misses a large amount of disease
risk prediction - not accrate
limited potential - misses out on spill over of info
hard to change individual behaviours
strength of population approach
equitable - attributable risk may be high where risk is low if a lot of people are exposed to the low risk
radical
large potential for the population
behaviourally appropriate
weaknesses
small advantage to the individual
poor motivation of the subject
poor motivation of the physician
benefit:risk ratio worrisome
where can health promotion operate
internationally
nationally - government, advertising, media
locally - GP, hospital, local authority, police, schools etc
individually- support groups, neighbourhood schemes, communities
may impact at level of
population
community
individual
smoking cessation and drs working with individuals

broader health promotion of drs
