Cinnamon supplementation in type 2 diabetes patients significantly reduces systolic and diastolic blood pressure, but doesn't significantly affect body weight and waist circumference.
This systematic review and meta-analysis diligently looked for related studies in databases like PubMed, Embase, Scopus, Web of Science and Cochrane Library. The search was conducted up to August 22, 2019, and aimed at finding the impact of cinnamon supplementation on blood pressure and certain anthropometric parameters among patients with type 2 diabetes. To gauge the effectivity, they used standard mean difference and confidence intervals. In cases of heterogeneity, fixed and random effect models were utilized. The collated data was analyzed using Stata 13. After refining the records, nine suitable articles were chosen for review.
The meta-analysis results indicated a significant decrease in systolic and diastolic blood pressure in type 2 diabetic patients following the incorporation of cinnamon in their diet. However, the supplement did not result in a significant change in their body weight, body mass index, and waist circumference. These fluctuations in anthropometric factors were noted, but they did not reach a level of statistical significance.
