摘要
【目的】研究广州市老城区社区中老年人宏量营养素摄入状况及其对血脂的影响。【方法】采取分层整群随机抽样的方法,在本地社区选取578名男性和804名女性,年龄为40岁以上,采取食物频数法调查膳食状况;测量体格状况,检测血清总胆固醇(TC)、低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)和甘油三酯(TG);以膳食供能营养素为自变量,分别选取TC、LDL-C、HDL-C、TG为因变量,以逐步法作多重线性回归,分析供能营养素与血脂的相关性。【结果】男、女膳食能量、蛋白质摄入量均高于膳食营养素参考摄入量(DRI)(P<0.05)。男、女碳水化合物占总能量比例分别为54.43%和52.69%,均在推荐的宏量营养素可接受范围(AMDR)内。男性脂肪占总能量比例(31.02%)略高于AMDR范围,女性(29.91%)在AMDR范围内,但达到上限值。血脂影响因素多重线性回归分析:男性LDL-C与膳食总能量和MUFA供能比相关(标准偏回归系数β分别为0.219和-0.132,P值均小于0.05),HDL-C与膳食总能量相关(β为-0.182,P<0.05),TG与PUFA供能比、膳食纤维摄入量、碳水化合物供能比相关(β分别为-0.218,-0.184和0.159,P值均小于0.05);女性TC与PUFA供能比、脂肪供能比相关(β分别为-0.188和0.193,P值均小于0.05),LDL-C与胆固醇摄入量、MUFA供能比相关(β分别为0.199和-0.176,P值均小于0.05),HDL-C与MUFA供能比相关(β=0.110,P<0.05),TG与脂肪供能比相关(β=0.143,P<0.05)。【结论】膳食总能量、胆固醇、膳食纤维的摄入量,以及碳水化合物、脂肪、单不饱和脂肪酸、多不饱和脂肪酸的供能比是影响血脂的重要因素。
【Objective】 To explore the dietary macronutrients intake in middle-aged and elderly residents of Guangzhou community, and their influence on blood lipid. 【Method】 Stratified and cluster randomized sampling method for selecting subjects was used. 578 male and 804 female, more than 40 years old, were enrolled in local communities in Guangzhou. The dietary status was assessed with food frequency questionnaire（FFQ）. Physical condition, plasma total cholesterol（TC）, triglycerides（TG）, high density lipoprotein-cholesterol（HDL-C） and low density lipoprotein-cholesterol（LDL-C） were measured. Energy-supplying nutrients were regarded as independent variables and plasma lipids as dependent variables when we performed stepwise multiple linear regression analysis to analyze correlation between energy-supplying nutrients and plasma lipids. 【Results】 The total energy（en） and protein intakes were beyond the Dietary Reference Intakes（DRI, 2013） in both men and women（P〈0.05）. Dietary carbohydrate proportions of total energy were 54.43% and 52.69% respectively in men and women, which were both well within the Acceptable Macronutrient Distribution Range（AMDR）. Dietary fat proportion of total energy was 31.02% in men, which was slightly above the AMDR, while the proportion in women was 29.91% and reached the upper limit of the normal range of AMDR. In a multiple linearregression analysis, LDL-C was correlated with energy intake and MUFA % en（standard partial regression coefficient β = 0.219 and-0.132, respectively, P〈0.05）, while HDL-C was correlated with energy intake（β =-0.182, P〈0.05） and TG was correlated with PUFA% en, dietary fiber intakes and carbohydrate % en（β =-0.218,-0.184 and 0.159, respectively, P〈0.05） in men. In women, TC was correlated with PUFA % en and fat % en（β =-0.188 and 0.193, respectively, P〈0.05）, while LDL-C was correlated with cholesterol intakes and MUFA % en（β = 0.199 and-0.176, respectively, P〈0.05）, HDL-C was correlated
