CHAPTER IV

DATA ANALYSIS AND INTERPRETATION

This chapter deals with the analysis and interpretation of the collected data to

assess the effect of biofeedback assisted relaxation among patients with hypertension.

The responses are tabulated and analysed under the following headings

Section I:

a) Distribution of background variables of patients with stage I hypertension in the

study and control groups (Tables 6 & 7)

b) Distribution of background variables of patients with stage II hypertension in

the study and control groups (Tables 31 & 32)

Section II:

a) Comparison of effect of BART on blood pressure and anxiety within and

between the groups among patients with stage I hypertension (Tables 8-28)

b) Comparison of effect of BART on blood pressure and anxiety within the groups

and between the groups among patients with stage II hypertension

(Tables 33-53)

Section III:

a) Relationship between blood pressure, anxiety and outcome of BART among

patients with stage I hypertension in the study and control groups

(Tables 29 & 30)

b) Relationship between blood pressure, anxiety and outcome of BART

among patients with stage II hypertension in the study and control groups (

(Tables 54 & 55)

Table 10 represents the overall level of blood pressure among patients between

the study and control groups before and after the intervention. During the pretest, all

patients in the study and control group belonged to stage I category with either systolic

BP in the range of 140-159 mm of Hg or diastolic BP in the range 90-99 mm of Hg.

During posttest III, 21(14%) of the study group and 5 (3.3%) of the control moved to

pre- hypertension. In the control group, 5(3.3%) patients moved to stage II

hypertension. There was significant difference between the groups, which was revealed

by the Chi square value was 20.06 with p value of 0.001.

The table 17 depicts that when the mean value of systolic BP for diuretics is

compared between the study and control groups, there is no significant difference

observed both during pretest and posttest III. The hypertensive patients on ACEI

showed a significant difference between the study and the control groups during

posttest III with t value of -2.85 and p value 0.006. The combination of Diuretics &

ACEI showed significant difference during both pre and posttests with t values of

-2.36 and -3.92. This was significant with p value of 0.023 and 0.0001 respectively.

CCBs also produced a significant difference between the study and control groups

during posttest III with t values of -2.93 and p value of 0.007 respectively.

Table 31 shows the distribution of demographic variables among patients with

hypertension in the study and control groups. Majority, 84 (52.6%) of the study group

and 77 (47.9%) of the control group belonged to the age group of 66-75 yrs. 63 (39.4%)

of the study group and 60 (37.1%) of the control group were residing in urban area.

Again, 7 (4.4%) of samples of the study group had primary education and 48 (30 %) of

the control group acquired collegiate education. The family type of 92 (57.7%) patients

of the study group and 90 (56.4%) of the control group was joint. Again 99 (62%) of

study group and 115 (72.1%) of the control group patients had monthly income in the

range of Rs. 15,001- 20,000. Majority, 160 (100%) of the study group and 149 (92.9%)

of the control group received support from their spouse.

The above table depicts that there is no significant difference in the distribution

of background variables between study and control groups except for the social support.

Table 54 depicts the correlation between the systolic and diastolic BP, state and trait anxiety , GSR & home practice during pre and post

tests in the study group. There was correlation between the systolic and diastolic BP, state and trait anxiety, GSR & home practice during pre

and post tests in the study group (table 55). During pretest, there was no correlation observed between anxiety and blood pressure. During

posttest III, significant positive correlation was observed between TA & SBP (r = 0.58) SA &SBP (r=0.82), SA& DBP (r =0.80). Significant

negative correlation was observed between GSR with SBP (r = -0.69), DBP(r = -0.90), SA (r = -0.11) & TA (r = -0.46). Negative correlation

also existed between total days of home practice with SBP (r = -0.36), DBP (r = -0.37), SA (r = -0.64), TA (r = -0.78) and GSR value (r = -0.32).

Table 56 depicts that the mean difference of systolic BP from pretest to posttest

III was 3.74 among patients with stage I hypertension and 0.19 for stage II hypertension.

The mean difference of diastolic BP from pretest to posttest III was 2.47 among patients

with stage I hypertension and 0.71 for stage II. For trait anxiety, the mean differences

were 9.40 and 1.73 for stage I and stage II respectively. The state anxiety mean

differences were 3.98 and 0.41 for stage I and II hypertension patients. Mean differences

for GSR among the stage I and II hypertension patients were 55.30 and 23.71. The mean

differences in the blood pressure, anxiety and GSR in the study group patients during

the pre and posttests between stage I Stage II hypertension patients was significant at

p<0.001 except for systolic BP, for which the change in the mean differences was not

statistically significant (t= 1.469 and p= 0.143) between the two stages of hypertension.
