成人膳食中类胡萝卜素摄入量与血脂关系

目的研究成人膳食中类胡萝卜素的摄入状况与血脂的关系。方法采用问卷调查法,调查130名35～60岁人群连续3 d的膳食情况,根据膳食摄入情况计算5种类胡萝卜素（包括α-胡萝卜素、β-胡萝卜素、β-隐黄质、番茄红素、叶黄素/玉米黄质）每日摄入量,将调查人群按类胡萝卜素摄入量四分位间距分组,观察类萝卜素的摄入量与血脂的关系。结果第1组人群血清甘油三酯水平明显低于第4组人群,差异有统计学意义（P〈0.05）。相关分析结果表明,类胡萝卜素的摄入量与血清中甘油三酯含量呈显著负相关（P〈0.05）。结论结果提示成人膳食类胡萝卜素的摄入与甘油三酯水平具有相关性,摄入类胡萝卜素可能对血脂有一定程度的保护作用。

The Relationship Between Carotenoids Intake and Serum Lipids in Adults

Objective To investigate the relationship between carotenoids intake and serum lipids in adults.Methods Dietary intake for a consecution of 3 days was investigated in 130 objects aged 35 to 60 years old by a questionnaire.Daily Intake of five carotenoids,including α-carotene,β-carotene,β-cryptoxanthin,lycopene and lutein/zeaxanthin,were calculated.The investigation objects were classified into four groups according to the quartiles of the carotenoids intake: Group 1(P100-P75),Group 2(P75-P50),Group 3(P50-P25),Group 4(P25-P0).The relationship between carotenoids intake and serum lipids was explored.Results The serum triglyceride level in Group 1 was significantly lower than that in Group 4(P<0.05).There was a negative correlation between the carotenoids intake and serum triglyceride level.Conclusions Serum triglyceride level in adult is correlated with the dietary intake of carotenoids.Carotenoids intake might protect lipids increase to some extent.
