The result revealed that out of 100 senior citizens 33(33%) were known hypertensive’s, 13(13%) were hypertensive’s but unaware the condition and 11(11%) had systolic hypertension. An overwhelming percentage (64%) of senior citizens had below average knowledge followed by 32%, 4% average knowledge and above average knowledge.
