The results of the present study showed that the mean age of patients in the control group was 51.44 years, in the intervention group, it was 52.77 years. The mean duration of hypertension was 3.35 years in the control group, 3.93 years in the intervention group. Other results related to demographic characteristics are shown in Table 1. The results of the Table 1 show that most participants were male, so that 66.7% and 62.2%, of the patients were male in the control and intervention groups, respectively. 100% of the patients in all tow groups were married. With regard to the level of education, only 8.9% of the patients in the control group had academic level of education, and this rate was 6.7%, for the intervention group, and rest of the patients did not have academic level of education. With regard to job status of the patients in all tow groups, most of them were self-employed and housewives. In the control group, 31.1% of the patients were self- employed and 31.1% were housewives. In the intervention group, 28.9% of the patients were self-employed and 26.7% were housewives. With regard to family history of hypertension, in the control group, 57.8% of patients had family history of hypertension, in the intervention group, 53.3% had family history of hypertension.

The results of Table 2 showed that in the control group and at the beginning of the study, 95% confidence interval for the mean score of quality of life in the physical domain was in the range of 18.09–19.46, and it was 14.56–15.69 for psychological domain, 6.50–7.25 for social domain, 17.82–19.64 for environmental domain, and 62.86–67.62 for total score of quality of life. One month after starting the study¸ 95% confidence interval for the mean score of quality of life in the physical domain was in the range of 17.18–18.52, and it was 13.99–15.10 for psychological domain, 7-7.79 for social domain, 16.24–18.01 for environmental domain, and 64.43–69.20 for total score of quality of life. Three month after starting the study¸95% confidence interval for the mean score of quality of life in the physical domain was in the range of 18.18–19.55, and it was 13.99–15.14 for psychological domain, 6.46–7.23 for social domain, 17.95–20.45 for environmental domain, and 63.48–69.11 for total score of quality of life. As the confidence interval between the various domains of life quality and overall life quality score¸ overlap one month after the beginning of the study and 3 months after the beginning of the study relative to beginning of the study, one can conclude that repeated measure test did not show any significant differences in the control group.
But in the intervention group before the educational intervention¸95% confidence interval for the mean score of quality of life in the physical domain was in the range of 18.18–19.55, and it was 15.01–16.14 for psychological domain, 7.11–7.90 for social domain, 18.56–20.37 for environmental domain, and 64.43–69.20 for total score of quality of life. One month after the educational intervention¸ 95% confidence interval for the mean score of quality of life in the physical domain was in the range of 23.59–24.53, and it was 20.32–21.18 for psychological domain, 9.33–9.90 for social domain, 24.49–25.94 for environmental domain, and 85.97–89.14 for total score of quality of life. three month after the educational intervention ¸95% confidence interval for the mean score of quality of life in the physical domain was in the range of 23.03–24.08, and it was 19.70- 20.56 for psychological domain, 9.33–9.90 for social domain, 26.16–27.57 for environmental domain, and 82.98–86.43 for total score of quality of life. As the confidence interval between the various domains of life quality and overall life quality score¸ did not overlap one month after the educational intervention and 3 months after the educational intervention relative to before the educational intervention, one can conclude that repeated measure test did show significant differences in the intervention group.
