The findings indicated that the DASH diet had a notable impact on decreasing systolic blood pressure (SBP), as demonstrated by a weighted mean difference (WMD) of -4.75 mmHg (95% confidence interval (CI): -6.23, -3.28; P < 0.001). Additionally, the DASH diet was found to have a significant influence on reducing diastolic blood pressure (DBP) [WMD of -4.17 mmHg (95% CI: -4.34, -4.00; P < 0.001)]. Subgroup analysis revealed that the results remained significant when age was &ge;50 years, in females, among ethnic groups from Europe, Asia, and America, as well as in groups classified as obese individuals.<br> <b>Conclusion</b>: The DASH diet has conclusive effects on blood pressure, especially in obese individuals. The DASH diet could be considered an important dietary strategy for the management of hypertension in obese and overweight adults.</span></span></div> Hypertension, Overweight, Obesity, Systematic Review, Meta-Analysis 10 22 http://goums.ac.ir/jorjanijournal/browse.php?a_code=A-10-1057-3&slc_lang=en&sid=1 Vahid Monfared 100319475328460010894 100319475328460010894 No Skeletal Biology Laboratory, College of Health, Oregon State University, Corvallis, OR 97331, United States Leila Sheikhi 100319475328460010895 100319475328460010895 No Food and Beverages Safety Research Center, Urmia University of Medical Science, Urmia, Iran Mohtaram Hashemi 100319475328460010896 100319475328460010896 No Student Research Committee, Semnan University of Medical Sciences, Semnan, Iran Fatemeh Kiani 100319475328460010897 100319475328460010897 No Student Research Committee, Semnan University of Medical Sciences, Semnan, Iran Reyhane Javid 100319475328460010898 100319475328460010898 No Student Research Committee, Semnan University of Medical Sciences, Semnan, Iran Mahya Nikoumanesh 100319475328460010899 100319475328460010899 No Student Research Committee, Varastegan Institute for Medical Sciences, Mashhad, Iran Yegane Ghelichi 100319475328460010900 100319475328460010900 No Student Research Committee, Varastegan Institute for Medical Sciences, Mashhad, Iran Alireza Hatami 100319475328460010901 100319475328460010901 No Department of Nutrition, School of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran Motahareh Hasani hasanimotahare@yahoo.com 100319475328460010902 100319475328460010902 Yes Department of Nutrition, School of Health, Golestan University of Medical Sciences, Gorgan, Iran
