Question 60 – Non-communicable diseases and lifestyle factors - Questions

In an epidemiological cohort study investigating the link between a high-salt diet (a lifestyle risk factor) and hypertension (a non-communicable disease), researchers tracked two groups over a 10-year period:

Group 1 (High-salt diet): $8,000\,$ participants, of whom 640 developed hypertension.
Group 2 (Low-salt diet): $12,000\,$ participants, of whom 360 developed hypertension.

Calculate the relative risk ( $R R$ ) of developing hypertension for individuals with a high-salt diet compared to those with a low-salt diet, and determine the correct epidemiological conclusion.

$R R = 2.67$ ; the study demonstrates a strong correlation, but correlation does not prove causation because confounding variables cannot be entirely ruled out.

$R R = 2.67$ ; the study proves a direct causal relationship because the relative risk is significantly greater than $1.0$ .

$R R = 1.78$ ; the study demonstrates a strong correlation, but correlation does not prove causation because confounding variables cannot be entirely ruled out.

$R R = 1.78$ ; the study proves a direct causal relationship because the relative risk is significantly greater than $1.0$ .
