,Introduction lecture 31-10-2022
Chronic diseases and lifestyle factors
Many chronic diseases are influenced by lifestyle factors
- Lifestyle factors: BRAVVO-acronyme
o Bewegen – Physical activity
o Roken - smoking
o Alcohol
o Voeding - Nutrition
o Veilige seks – Safe sex
o Ontspannen/stress - stress
- Risk factor: when unhealthy behavioral choices are made
o PA à low levels of PA become a risk factor for chronic disease
o Smoking à >10 cigarettes a day
o Alcohol à >7 units a day
Levels of influence over human behavior: socio-ecological model
Different levels of influence on human behavior
Defining Health Promotion and Disease Prevention
Health Promotion = Maintaining people’s current health
status. And ideally shifting towards better health.
Disease Promotion = Preventing people getting a
disease. And prevent a shift towards the seriousness of a
disease.
Examples – HP vs DP
- Smoking reduction with the aim of maintaining an optimal respiratory and CV-
system à HP
- Smoking reduction with the aim to reduce the chance of getting lung cancer à DP
Relation between HP and DP
- Many lifestyle factors focus initially on Health Promotion
o E.g., increasing PA, lowering fat intake, reducing smoking
, - And then have an effect on Disease Prevention
o E.g., preventing obesity or cancer
Types of prevention
- Primary prevention = to prevent (development) disease and illness.
To promote a healthy lifestyle.
- Secondary prevention = early detection of a disease/ screening of
disease e.g., cancer screening
- Tertiary prevention = prevent/ reduce the seriousness or
complications of diseases.
- Palliative care = end of life care, to relieve the pain of the patient, mostly for
terminally ill people.
Prevention can be target at different population levels
- Universal
o Designed to reach entire population, without regard to individual risk factors
and intends to reach a very large audience.
- Selective
o Targets subgroups of general population that are determined to be at risk.
Subgroups may be distinguished by traits such as age, gender, family history,
economic status, etc.
- Indicated
o Involves a screening process and aims to identify individuals who exhibit early
signs of a disease and other problem behaviors.
Intervention levels, and tools or instruments
- Eliminate, restrict, disincentive e.g., legislature/ law, sanctions
- Incentive, shift, enable e.g., pricing, nudging, facilities
- Enable, educate e.g., education, training
Real-life setting
- HPDP requires multifactorial interventions in the complexity of real-life settings.
- Individual move from setting to setting and constantly making lifestyle choices
influenced on different levels (intra, interpersonal, institutional, community, policy).
Consequently, interventions are often aimed at a specific setting.
- Definition of a setting: physical and recognizable structure with predefined
geographical boundaries.
