The effects of purslane consumption on anthropometric measurements and blood pressure have been studied in numerous experiments. However, the research findings conflict with one another. In order to assess the impact of purslane on weight, body mass index (BMI), waist circumference (WC), systolic blood pressure (SBP), and diastolic blood pressure (DBP), this meta-analysis was carried out. Up until February 2023, PubMed, Web of Science, Scopus, Google Scholar, and the reference lists of the identified pertinent randomised controlled trials (RCTs) were all searched. The random-effects model was used to calculate the effect size and then to describe it as a weighted mean difference (WMD) and 95 % confidence interval (CI) (CRD42023427955). The systematic review was able to incorporate seven RCTs. Meta-analysis showed that purslane significantly decreased body weight (WMD): -0⋅73 kg, 95 % confidence interval (CI): -1⋅37, -0⋅09, =0⋅025), BMI (WMD: -0⋅35 kg/m, 95 % CI: -0⋅64, -0⋅07, =0⋅016), and SBP (WMD: -3⋅64 mmHg, 95 % CI: -6⋅42, -0⋅87, = 0⋅01), and for WC, there was no discernible effect (WMD: -0⋅86 cm; 95 % CI, -1⋅80 to 0⋅07; = 0⋅06) and DBP (WMD: -0⋅36 mmHg; 95 % CI, -1⋅75 to 1⋅03; = 0⋅61). Purslane consumption, especially in participants with a BMI of <30, might play a role in decreasing SBP, body weight, BMI, and WC. Purslane consumption significantly reduced body weight, BMI, and SBP; however, WC and DBP did not experience a reduction. More investigation is needed to verify the impact of purslane consumption on anthropometric parameters and blood pressure.
在众多实验中，人们研究了食用马齿苋对人体测量指标和血压的影响。然而，研究结果相互矛盾。为了评估马齿苋对体重、体重指数（BMI）、腰围（WC）、收缩压（SBP）和舒张压（DBP）的影响，进行了这项荟萃分析。截至2023年2月，检索了PubMed、科学网、Scopus、谷歌学术以及已识别的相关随机对照试验（RCT）的参考文献列表。采用随机效应模型计算效应量，然后将其描述为加权平均差（WMD）和95%置信区间（CI）（CRD42023427955）。该系统评价纳入了7项随机对照试验。荟萃分析表明，马齿苋显著降低了体重（WMD：-0.73kg，95%置信区间：-1.37，-0.09，P=0.025）、BMI（WMD：-0.35kg/m²，95%置信区间：-0.64，-0.07，P=0.016）和SBP（WMD：-3.64mmHg，95%置信区间：-6.42，-0.87，P=0.01），而对于WC，没有明显影响（WMD：-0.86cm；95%置信区间，-1.80至0.07；P=0.06），对于DBP也没有明显影响（WMD：-0.36mmHg；95%置信区间，-1.75至1.03；P=0.61）。食用马齿苋，尤其是BMI<30的参与者，可能在降低SBP、体重、BMI和WC方面发挥作用。食用马齿苋显著降低了体重、BMI和SBP；然而，WC和DBP并未降低。需要更多的研究来验证食用马齿苋对人体测量参数和血压的影响。
