Q

Is the DALY (disease adjusted life years) burden of AF increasing or decreasing? What are three factors contributing to this?

A
  • It is increasing
  • This is due to:
    1. Population growth
    2. Population ageing
    3. More AF cases

Q

Why does improved survival rates of CVD increase AF cases?

A

Because people are more likely to survive longer and develop AF

20
Q

Describe the risk factors for coronary heart disease

A
  • Age
  • Sex
  • Hypertension
  • Hypercholesterolaemia
  • Smoking
  • Diet
  • Low HDL cholesterol
  • Obesity
21
Q

Risk factors for AF

A
  • Hypertension
  • Coronary heart disease
  • Valvular heart disease
22
Q

How does smoking affect the lungs?

A

Impairs the pulmonary and immune function. Impairs function, and can cause conditions such as COPD and cancer

23
Q

How does smoking influence clearance rate of particles in the lungs? How?

A

It decreases it, by decreasing the effectiveness of the mucocilliary escalator

24
Q

How does smoking increase risk of infection?

A
  • Increasing reliance on coughing to clear infection
  • Retention of particles, leading to infection
  • Impairs innate immune system and prompts inflammation
25
How does smoking impact lung function?
- Triggers inflammatory response that leads to destruction of functional lung tissue
26
What percentage of long-term smokers will develop COPD?
15-20%
27
There is one way to reduce loss of lung function for smokers with COPD. What is it?
Smoking cessation
28
What is the most common cancer in the world?
Lung cancer
29
Are men or women more likely to smoke overall?
Men
30
What is the correlation between education and income status and smoking?
Lower income and education corresponds with higher rates of smoking
31
Effect of mental illness on smoking rate
Increased prevalence
32
Effect of age on smoking status
Middle ages smoke the most, youngest and oldest smoke less
33
Are indigenous people more likely to smoke than non indigenous people?
Yes
34
How does smoking DRIVE social inequality?
- Disparity in mortality rates - High cost of cigarettes
35
Describe some ways in which health policy contributed to the effectiveness of smoking prevention
1. Taxation and pricing (leveraging price sensitivity) 2. Public education campaigns (reduce social proof) 3. Advertising and sponsorship bans 4. Smoke-free areas 5. Support for quitting 6. Health warnings on packaging
36
How do media prevention campaigns act at an individual and social level to decrease smoking?
Individual: Prompt quitting by conveying downsides Population: Decrease social proof
37
Upstream vs downstream public health factors
Upstream: macroscopic factors that influence health outcomes Downstream: providing equitable access to care
38
What are targeted strategies in the context of public health?
Interventions that target a specific subsection of the population based on demographic, behaviour, or other such criteria (as opposed to the whole population).
39
What is planetary health?
Health of mankind and the natural systems on which it depends
40
What is climate change?
- Climate change refers to long-term shifts in temperatures and weather patterns - It can be natural, due to natural changes, or human-induced, such as in the burning of fossil fuels
41
How can climate change increase risk of haematological pathology?
- Disruption of natural resources -> economic disparity -> risk factor for anaemia - Reduced crop yields and, in some instances, reduced iron content due to increased temp/CO2 concentrations, a risk factor for iron deficiency anaemia
42
Climate change mitigation vs adaptation
Mitigation: stopping Adaptation: adjusting to consequences of
43
Climate change mitigation strategies
- Renewable energy sources - Public transport/cycling to work - Taxing non-renewable energy
44
Climate change adaptation strategies
- Diversifying crops to ensure solid food supply - Preparing supply chains and transport systems to better withstand extreme weather events
45
List some ways in which climate change is threatening the population
- Rising sea level -> people displaced (refugees) - Decreased food security caused by altered crop yields - Increased natural disasters
46
What are some sources of greenhouse gas?
- Livestock - Transport - Industry/Energy - Health care
