Definition • Prevention in GT is concerned with technological measures to avoid from happening certain health problems that otherwise are likely to appear or get worse in the future. • Engagement (‘moral commitment’) is the measures taken by a person him/herself to avoid certain possible future health problems happening (proactive prevention). Prevention/engagement method Herman Bouma May 23, 2006
General prevention in GT is technological measures taken to remain healthy with no particular disease in mindSpecific prevention in GT is technological measures taken to avoid particular diseases or accidents(e.g. vitamins against Age related Macula Degeneration = AMD) Public Health Engineering: fresh water supply; sewage systems, airbags, safety belts, helmets, traffic safety measures, vaccination,….. Private measures: maintain physical, cognitive (mental), and social activities; avoid unhealthy habits and diet; maintain normal blood circulation; home ventilation, hip protectors; vitamins against age-related macular degeneration (AMD), …….

Interventions • Control of environment(natural and man-made hazards) • Living conditions • Personal behaviour and lifestyle • Early detection of disease • Rehabilation programme Prevention/engagement method Herman Bouma May 23, 2006
Aspects of methodology • Define precise purpose of intervention (matrix cell) • Select aging target group • Select way of intervention • Find representative subjects • Prepare in-depth interviews, partly open • Define proper control group • Start with pilot experiment Prevention/engagement method Herman Bouma May 23, 2006
ExampleThere exists no way to prevent or heal age-related macula degeneration(AMD) which runs partly in families. However, there are some indications that vitamins may have some positive effect. In a longitudinal study it is found that people who happen to eat certain anti-oxydants get less AMD than other people.How to set up an intervention study for preventing AMD?Purpose of interventionTarget group and control group (age, genetics, eye colour; visual acuity, retinal inspection, group sizes)Intervention ( type of vitamins, dose, duration)Result (retinal inspection-fundus photography,visual acuity)Statistical treatmentEthics Prevention/engagement method Herman Bouma May 23, 2006
Conclusion • Define research problem carefully • Collaborate with health professional • Select promising intervention • Select experimental and control group • Choose statistics carefully • Start with pilot investigation • Consider ethics and ask permission Prevention/engagement method Herman Bouma May 23, 2006
