摘　　要：目的了解社区人群膳食奶制品摄入频率与循环奇数碳饱和脂肪酸(OCFAs)的相关性。方法于2018年9月—2019年9月在广州市黄石街社区卫生服务中心招募符合条件的726名志愿者作为研究对象,采用面对面调查的方式收集对象一般情况、膳食情况;进行身体测量并采集12 h空腹静脉血用于检测红细胞膜奇数碳饱和脂肪酸。结果社区30~69岁人群牛奶、奶粉、酸奶摄入频率低于1次/周者分别占总人群的55.6%、85%及75.8%,≥4次/周者占比分别为20.8%、7.3%和6.4%;牛奶、奶粉和酸奶的平均摄入量分别为71.4 ml/d、8.6 g/d和21.4 g/d;偏相关分析显示校正了社会人口学和膳食混杂因素后,牛奶的摄入频率与红细胞膜OCFAs、PA、HA均呈相关,r分别为0.314、0.423和0.123(P<0.05),奶粉的摄入频率与PA呈正相关(r=0.155,P<0.05),酸奶与OCFAs及其组分均不相关;牛奶和奶粉的摄入量与PA(r=0.674、0.569)及总OCFAs(r=0.481、0.509)呈中等强度正相关,与HA呈弱相关(r=0.123、0.187);酸奶与OCFAs、PA及HA均无相关关系。结论该社区30~69岁人群奶制品摄入频率普遍偏低;增加牛奶和奶粉的摄入有利于提高人群红细胞膜OCFAs及其组分的构成。Objective To investigate the relationship between dairy food intake frequency and circulation odds-chain fatty acids(OCFAs)among community population.Methods Seven hundred and twenty-six volunteers were recruited as study objects from Huangshi Street Community Healthcare Center of Guangzhou from September,2018 to September,2019.The general situation and diet of the subjects were collected by face-to-face investigation.The 12 hour fasting venous blood were collected to detect the odds-chain saturated fatty acids composition of erythrocyte membrane.Results Among the community population aged from 30 to 69 years old,the intake frequency of milk,milk powder and yogurt less than one time a week accounted for 55.6%,85%and 75.8%of the total population,respectively.And for those more than 4 times a week the ratio were 20.8%,7.3%and 6.4%,respectively.The average intake of milk,milk powder and yogurt was 71.4 ml/d,8.6 g/d and 21.4 g/d,respectively.Partial correlation analysis showed that,after adjusting for sociodemographic and dietary confounding factors,the frequency of milk intake was correlated with erythrocyte membrane OCFAs,PA and HA,with r=0.314,0.423 and 0.123,respectively(P<0.05).The frequency of milk powder intake was positively correlated with PA(r=0.155,P<0.05).There was no correlation between yogurt intake and OCFAs and its components.The intake of milk and milk powder was moderately positively correlated with PA(r=0.674,0.569)and total OCFAs(r=0.481,0.509),and weakly correlated with HA(r=0.123,0.187).There was no correlation between yogurt intake and OCFAs,PA and HA.Conclusions In the community,dietary intake of dairy products among people aged 30-69 is low.Increasing milk and milk powderconsumption can enhance the composition of OCFAs and theircomponents in erythrocyte membranes.
