Efektivitas Diaphragmatic Breathing Exercise Terhadap Tekanan Darah Pada Penderita Hipertensi Di Kota Palembang

Background : DBE is a non-pharmacological intervention that is currently
trending for lowering blood pressure through relaxation. Hypertension can lead to
serious complications such as heart disease, stroke, and kidney failure, making
early control important. DBE is needed as a supportive therapy in addition to
medication.
Objective : Knowing the effectiveness of DBE on blood pressure in hypertension
patients in Palembang City
Methods : Quantitative research with a quasi-experimental non-equivalent control
group design. The population was 182 people. A sample of 70 respondents (35
intervention, 35 control) was selected using purposive sampling. Data were
collected using observation sheets. Univariate and bivariate analyses were
conducted using the Wilcoxon signed-rank test and Mann-Whitney U test.
Result : The majority of respondents in both groups were pre-elderly (68.6%),
female (intervention 82.9%; control 60%), had a secondary education, and most
were taking amlodipine (88.6%). The intervention group had a higher proportion
of unemployed individuals (65.7%) and those who had been ill for ≥1 year (60%),
whereas the control group had a higher proportion of employed individuals (60%)
and those who had been ill for <1 year (51.4%). Before the intervention, all had
stage 1 hypertension. After DBE, the blood pressure reduction in the intervention
group was greater (systolic 9.26 mmHg; diastolic 7.23 mmHg) compared to the
control group (systolic 4.54 mmH,; diastolic 3.91 mmHg). The Mann-Whitney test
showed p=0.013 (Z= -2.226, mean rank intervention 30.86, control 40.14).
Conclusion : There is a difference in blood pressure post-test and post-test between
the intervention group and the control group in hypertensive patients
Suggestion : DBE can independently lower blood pressure in people with
hypertension.
