Which of the following is a recognised driver of past mortality improvement at older ages in developed countries that is most directly linked to medical advances?
Reduced deaths from cardiovascular disease, through better treatment and prevention, is a major driver of mortality improvement at older ages. Rising obesity or smoking would worsen mortality, and selection at inception is not a population-level driver.
- AReduced deaths from cardiovascular disease through better treatment and preventionCorrect
- BIncreased deaths from infectious disease
- CHigher selection at policy inception
- DRising obesity rates alone
- Increased smoking prevalence among men
Explanation
Falling cardiovascular mortality, due to improved treatment and prevention, has been a major driver of improvement at older ages. Rising obesity and increased smoking would worsen mortality, and selection is not a population trend driver.

One question tells you little. A timed set on Mortality projection shows your real accuracy, how long you take and where you lose marks.
