厦门大学第一附属医院刚刚在《亚太临床营养学杂志》发表了一项研究结果,该项研究对比了170名僧众和126名食肉者,发现体重指数 (BMI) 越高,血脂水平和心血管风险越高。然而,这种相关性在素食僧众显著减弱。因为素食,不仅降低了僧众的BMI,同时也降低了高BMI与高血脂/血浆脂蛋白和高心血管疾病风险间的相关性。

 

【编注】体重指数:Body Mass IndexBMI,是目前国际上常用的衡量人体胖瘦程度以及是否健康的一个标准。

体重指数(BMI=体重(kg÷身高2m

例如:某男性,身高1.75米,体重70公斤,其BMI=70Kg ÷ 1.752 =22.86

 

成人的BMI数值:

【摘要】

肥胖与高脂血症和心血管疾病息息相关。在肥胖及高血脂普遍存在的西方国家,早已普遍证实了素食对健康的益处。本研究对中国南方人群的体重指数(BMI)与不同血脂/血浆脂蛋白水平之间的相关性进行了研究,同时也研究了BMI与中国南方低心血管疾病风险人群之间的相关性。本研究对170名素食的僧众和126名食肉者进行了研究。根据年龄、教育程度、吸烟、饮酒、体育锻炼等进行了校准,对BMI与素食主义者状态间的相互作用进行了多变量回归分析。

 

素食僧众的平均BMI、血压、总胆固醇、低密度脂蛋白(LDL)、总胆固醇/高密度脂蛋白比值,甘油三酯(TG)、载脂蛋白B、载脂蛋白A-I显著低于食肉者,同时素食僧众的心血管疾病风险亦低于食肉者。在素食者与食肉者中均发现:高BMI与血脂/血浆脂蛋白水平的不利影响以及心血管疾病风险之间具有相关性。然而,在素食僧众中,这种相关性明显降低。

 

结论:素食不仅降低了BMI,同时也降低了和BMI相关联的导致动脉粥样硬化的血脂/血浆脂蛋白与心血管疾病风险间的相关性。

[Abstract]

Obesity is related to hyperlipidemia and risk of cardiovascular disease. Health benefits of vegetarian diets have well-documented in the Western countries where both obesity and hyperlipidemia were prevalent. We studied the association between BMI and various lipid/lipoprotein measures, as well as between BMI and predicted coronary heart disease probability in lean, low risk populations in Southern China. The study included 170 Buddhist monks  (vegetarians) and 126 omnivore men. Interaction between BMI and vegetarian status was tested in the multivariable regression analysis adjusting for age, education, smoking, alcohol drinking, and physical activity. Compared with omnivores, vegetarians had significantly lower mean BMI, blood pressures, total cholesterol, low density lipoprotein cholesterol, high density lipoprotein cholesterol, total cholesterol to high density lipoprotein ratio, triglycerides, apolipoprotein B and A-I, as well as lower predicted probability of coronary heart disease. Higher BMI  was associated with unfavorable lipid/lipoprotein profile and predicted probability of coronary heart disease in both vegetarians and omnivores. However, the associations were significantly diminished in Buddhist vegetarians.  Conclusions: Vegetarian diets not only lower BMI, but also attenuate the BMI-related increases of atherogenic lipid/lipoprotein and the probability of coronary heart disease.
