中国居民代谢综合征与膳食营养素的相关性研究

Relation between metabolic syndrome and dietary nutrients intake in China

目的探讨中国居民代谢综合征与膳食营养素摄入的关系。方法数据来源于2002年中国居民营养与健康状况调查,选择15岁以上人群40 708人,其中男性19 543人,女性21 165人。代谢综合征的定义采用中华医学会糖尿病协会推荐的标准,膳食数据利用连续3 d 24 h回顾法。结果单因素分析表明,代谢综合征与蛋白质、脂肪、胆固醇、总维生素E、钙、镁、铁、钾、钠的摄入呈正相关(P均<0.05),而碳水化物、胡萝卜素、维生素C的摄入与代谢综合征呈负相关(P均<0.05);多因素调整年龄、性别、6类地区、教育程度、中重度体力活动、饮酒、吸烟后,能量摄入与代谢综合征呈正相关,但调整BMI后,能量则不具有统计学意义(P>0.05),其它营养素经上述多因素及能量的调整后发现,胡萝卜素、维生素A、视黄醇摄入与代谢综合征呈负相关(P均<0.05),总维生素E及钠的摄入与代谢综合征呈正相关(P均<0.05)。结论营养素的摄入与代谢综合征患病有关,应提倡健康饮食,以预防和控制代谢综合征相关的心血管病的发生。

Objective To explore the relation between metabolic syndrome and dietary nutrients intake in Chinese people. Methods Data were presented for 19 543 men and 21 165 women aged more than 15 years old,the standard was according to the National Nutrition and Health Survey, 2002. The metabolic syndrome definition was recommended by the CDS. The three consecutive 24 hour-method was used in dietary survey. Results The metabolic syndrome was significantly and positively related with dietary protein, fat, cholesterol, total vitamin E, calcium, magnesium,iron, potassium, sodium, and significantly and negatively related with CHO, carotene, vitamin C in uni-variate logistic analysis. After being adjusted for age, sex, area, education, physical activity, smoking and drinking, there was a positive relation between the metabolic syndrome and energy intake. However,further adjusted by BMI, no significant relation was found. In multi-variate analysis,the metabolic syndrome was negatively related with dietary carotene,vitamin A and retinol, and positively related with vitamin E and sodium intake. Conclusion The dietary nutrients intake is related with metabolic syndrome, healthy lifestyle should be publicized to prevent metabolic syndrome related to cardiovascular diseases in Chinese people.
