te was 71.52%; 81% in AKU, 80% in DUHS and 49.6% in ZMU.
Mean (SD) age of participants was 57.7(12) years, 224(50.1) were men and 223(49.8) were women. In ethnicity 108(24.3) were of Muhajir ethinicity. In education, 208(46.5) had > 10 years formal education. Comorbid conditions are shown in Table 1. Mean (SD) duration of hypertension was 9.9(7.42) year, Systolic blood pressure was 135.1(22.4), Diastolic blood pressure was 84.4(13.2). Controlled hypertension was present in 72.3%(323) and uncontrolled hypertension was present in 27.4%(124).
Outcome of knowledge is reported as percentage(n) and mean(SD) scores have also been computed. Table 1. On computing knowledge scores for each item question, the total mean (SD) score was 20.97(4.93) out of a maximum score of 38.
Comparison of knowledge in men and women
On comparison of individual item question in men and women%(n); 57.7(128) men and 35.5(78) women agreed that hypertension means high blood pressure (p value <0.001), 93.5(203) man and 92.5(205) women agreed that hypertension can be dangerous (p value 0.93), 79.4(177) men and 60.5(135) women said that systolic blood pressure (SBP) should be <140 mm hg (p value <0.001), 78.6(176) men and 58.3(130) women said that diastolic blood pressure (DBP) should be < 90 mm hg (p value <0.001), 26.7(58) men and 11.8(26) women said that both SBP and DBP are important to control (p value <0.001, 88.8(192) men and 91.2(197) agreed that lowering blood pressure improves health (p value 0.82), 45.8(99) men and 33(71) women agreed that high blood pressure can be asymptomatic (p value 0.006), 82.8(184)men and 84(186) agreed that changing lifestyle improves blood pressure (p value 0.5), 76(166) men and 73.3(162) women agreed that hypertension is a lifelong disease (p value 0.3), 77(174) men and 72.8(161) women agreed that antihypertensives have to be taken for life (p value 0.4), 57.3(126) men and 50.4(112) said that high blood pressure is a part of aging (p value 0.4) The mean (SD) knowledge score in men was 21.8(4.9) and in women was 20.07(4.8) (p value <0.001).
Comparison of demographics and knowledge in patients with uncontrolled and controlled hypertension
On comparison of demographics of patients with controlled and uncontrolled hypertension, there was statistically significant difference in; Mean (SD) age (59.05 years (11.2) v 54.33 years (13.4)p <0.001), gender (38.3% males v 11.9% males p 0.03),> 10 years of formal education (38.7% v8.1% p <0.001). Comorbids and history of hospitalization is shown in Table 1.
On comparison of questions related to knowledge, there was statistically significant different in; meaning of hypertension (p <0.001), target SBP (p0.001), target DBP (p 0.001), importance of SBP versus DBP, improvement of health with lowering of blood pressure (p 0.002), high blood pressure being asymptomatic (p <0.001), changing lifestyle improves blood pressure (p 0.003), hypertension being a lifelong disease (<0.001), lifelong treatment with antihypertensives (<0.001) and high blood pressure being part of aging (<0.001) (Table 2).
On comparison of knowledge as a composite score between uncontrolled and controlled hypertensive; Mean (SD) was 21.85(4.74) v18.67 (4.70) (p value :< 0.001) Knowledge score on most of individual item questions between the two group was significantly different (Table 3).
On univariate linear regression for outcome of knowledge score; β(95% CI) was 0.064(0.026,0.102) for age, 1.79(0.89,2.69) for gender,-1.93(−3.3,-0.5) for sindhi ethinicity, -1.66(−3.23,-0.84) for Punjabi ethinicity, -2.22(−4.64,0.18) for balochi ethnicity, -2.84(−4.23,-1.44) for pukhtoon ethinicity, -0.95(−2.21,0.31) for Muhajir ethinicity, -0.99(−2.5,0.54) for education up to <5 years,-1.14(−2.68,0.39) for < 10 years of education, 0.75(−0.48,2.03) for >10 years of education, 0.47(−0.51,1.46) for history of hospitalization for uncontrolled hypertension, -3.17(−4.15,-2.19) for having uncontrolled hypertension. However on multivariate analysis gender β(95% CI) 1.67(0.75,2.59) p <0.001,uncontrolled blood pressure; -2.70(−3.76,-1.67)p <0
