Background: Hypertension is a major health issue, affecting young population world-wide. A lifestyle modification approach can decreases the effects of high blood pressure level in the hypertensive patients. This study aimed to assess practice of non-medical management of hypertension and associated factors among hypertensive patients attending public hospitals in Hawassa city, Sidama, Ethiopia. Method: Facility based cross sectional study was conducted from Feb. 2023 to May 2023, among sample of 300 hypertensive patients. A systematic random sampling technique was used to select study participants. A pre-tested and structured interviewer questionnaire was used to collect data. The data was entered into Epi-Data version 4.2 and exported into SPSS version 26 for analysis. Bi-variable logistic regression was used to identify the association between independent variables and dependent variable. Variables with p≤0.25 from the bi-variable analysis were entered into a backward stepwise multivariable logistic regression model, and significant variables (p<0.05) were retained in the multivariable model. Result: This study shown that, the prevalence of good practices toward non-medical managements of hypertension is, 62.3 %( n=187) (95%CI: 56.5-67.3), 224 (74.7 %) had good Knowledge, and 195 (65. %) had favorable attitudes. Good knowledge level (AOR =2.368; 95% CI: 1.354-4.141, p-value=0.003), favorable attitude (AOR=2.054; 95% CI: 1.180-3.575, Pvalue=0.011), and having family history of hypertension (AOR=1.764; 95% CI: 1.073-2.899, pvalue=0.025) were statistical significant association with practices of non-medical managements of hypertension. Conclusion: In this study nearly two-third of study participants had good practice of nonmedical managements of hypertension. Good level of knowledge, favorable attitude toward nonmedical managements of hypertension and having family history of hypertension had statistically significant association with practices of non-medical managements of hypertension. Therefore hypertensive patient’s knowledge and attitude should be improved toward non-medical managements of hypertension by health care providers.
