Journal Title: International Journal of Health Sciences and Research - Year 2017, Vol 7, Issue 11
Abstract
Background: Hypertension is more prevalent in India and risk factors for hypertension are classified into modifiable and non-modifiable. Objectives: To find out meta-analytic studies that investigate the alteration of modifiable risk factors such as engaging physical activity, weight reduction, yoga; reduction of stress, alcohol consumption, salt/sodium; vegetarian or DASH diet consumption on blood pressure. Methodology: Systematic search was done on February 2015 in Google Scholar search engine using scientific terms yielded more than 8,00,000 articles. We systematically screened 3000 titles. After inclusion and exclusion criteria, we found 20 articles for final analysis. Results: 4 articles on physical activity showed mean reduction of 3.46 mmHg in SBP and 1.28 mmHg in DBP. 2 articles on weight reduction showed mean difference of -5.37 mmHg in SBP and -3.49 mmHg in DBP. 2 articles on yoga showed mean reduction of 4.69 mmHg in SBP and 4.3 mmHg in DBP. 5 articles on salt reduction showed mean difference of -2.57 mmHg in SBP and -1.58 mmHg in DBP. 3 articles on alcohol reduction showed mean difference of -3.31 mmHg in SBP and -2.04 mmHg in DBP. 2 articles on DASH diet showed mean reduction of 5.0 mmHg in SBP and 2.98 mmHg in DBP. 2 articles on stress reduction in the form of transcendental meditation showed mean difference of -4.9 mmHg in SBP and -3.0 mmHg in DBP. Conclusion: Modification of above modifiable hypertension risk factors are significantly reduces blood pressure. Reduction effect is more pronounced in hypertensive subjects hence used as first line treatment option.
