In a cross-sectional survey of 1000 individuals, 40 have hypertension and of these 28 are on antihypertensive treatment. Of the 28 treated, 20 have controlled BP (< 140/90 mmHg). What is the proportion of hypertensives with controlled hypertension among all hypertensives?
- A 71.4%
- B 50% ✓
- C 28%
- D 20%
Correct answer: B. 50%
Explanation
Controlled hypertension among all hypertensives = 20/40 = 50%. This is distinct from control rate among treated (20/28 = 71.4%) and treatment coverage (28/40 = 70%). The cascade of hypertension care framework tracks awareness, treatment, and control separately.
