The 20 questions

  1. What is the tendency for people to believe they are less at risk of CVD than others called?

    • Recall bias
    • Optimism bias
    • Availability heuristic
    • Confirmation bias
  2. Which cognitive heuristic causes people to overestimate the risk of rare, dramatic events?

    • Selection bias
    • Availability heuristic
    • Optimism bias
    • Placebo effect
  3. What is the energy content of 1 g of fat, approximately?

    • 380 kJ
    • 4 kJ
    • 38 kJ
    • 17 kJ
  4. A person has a daily excess intake of 1000 kJ. How much fat is stored over 7 days?

    • 184 g
    • 26 g
    • 700 g
    • 1840 g
  5. What occurs when a person's energy intake exceeds their total energy expenditure over time?

    • Constant weight
    • Weight gain
    • Muscle atrophy
    • Weight loss
  6. What medical condition is a direct long-term consequence of a positive energy balance?

    • Obesity
    • Anorexia
    • Scurvy
    • Hypothermia
  7. What do health studies primarily calculate energy budget data to monitor?

    • Blood pressure
    • Enzyme activity
    • Genetic mutation
    • Energy imbalance
  8. Why does a correlation between fast food and high BMI fail to prove direct causation?

    • Sample size is large
    • Data is continuous
    • Measurement is accurate
    • Confounding variables exist
  9. A person has a BMI of 35 and a waist-to-hip ratio of 1.0. What is their health status?

    • High CVD risk
    • Ideal body weight
    • Underweight
    • Low CVD risk
  10. What psychological factor leads people to underestimate lifestyle health risks?

    • Scientific literacy
    • Sense of control
    • High anxiety
    • Statistical training
  11. Why are long-term dietary health risks often perceived as less serious than dramatic events?

    • They are genetically determined
    • They affect public health
    • They happen instantly
    • Risks accumulate gradually
  12. What happens to body mass when daily energy intake equals daily energy expenditure?

    • Increases rapidly
    • Fluctuates wildly
    • Decreases steadily
    • Remains constant
  13. What term describes the minimum energy expended by the body at rest to maintain vital functions?

    • Active metabolic rate
    • Basal metabolic rate
    • Total daily expenditure
    • Specific dynamic action
  14. Which measurement is divided by height squared to calculate Body Mass Index?

    • Body fat percentage
    • Basal metabolic rate
    • Waist circumference
    • Body mass
  15. How do people typically perceive common, familiar health risks compared to rare dramatic ones?

    • They evaluate them accurately
    • They overestimate them
    • They underestimate them
    • They ignore them entirely
  16. How does a perceived lack of individual control affect a person's risk perception?

    • Risk is underestimated
    • Risk remains accurate
    • Risk is ignored
    • Risk is overestimated

    • 500 kJ
    • 140 000 kJ
    • 1 400 kJ
    • 14 000 kJ
  18. Which state is created when daily energy intake is less than daily energy expenditure?

    • Negative energy balance
    • Positive energy balance
    • Basal metabolic equilibrium
    • Zero energy balance
  19. What change in average body weight occurs over time during a negative energy balance?

    • Rapid fluctuation
    • No change
    • Weight loss
    • Weight gain
  20. Which health indicator is calculated by dividing mass in kilograms by height in metres squared?

    • Body fat percentage
    • Body mass index
    • Waist-to-hip ratio
    • Basal metabolic rate
