江苏省居民食物结构与营养水平调查研究

通过食物消费量计算和抽样膳食调查进行了江苏省居民膳食结构与营养水平的研究。结果表明:80年代中期是本省在总体上解决温饱问题的转折点;但动物性食物的消费量尚处于较低水平。食物消费量计算较膳食调查结果人均日粮食摄取量高约70g,动物性食物低近18g,因而能量与营养素摄取量也不尽相同,而能量与蛋白质的动物性来源则膳食调查高于食物消费量计算约4％。认为调查结果更符合实际,表现了膳食结构处于调整阶段的倾向,但营养素摄取仍不够平衡。食物摄取与营养水平城乡间差别明显,县际间也有较大差别。健康水平有提高,体格测量结果与营养水平的关系尚难确定。建议适当提高动物性食物和豆类的摄取,但动物性脂肪不宜过高。据此提出了江苏省居民2000年的食物结构设想,并应根据各地不同情况区别要求。另外对膳食结构的DDP评分方法也进行了初步讨论。

INVESTIGATION OF THE DIETARY PATTERN AND NUTRITIONAL LEVELS OF THE INHABITANTS IN JIANGSU PROVINCE

A study on the dietary pattern and nutritional levels of the inhabitants in Jiangsu province was carried out by means of both analysis of food consumption and dietary survey. The results showed that the problem of basic need for food has been resolved in this province since the 1980's mid-period, but animal food consumption was still low relatively.Compared with the data obtained from dietary survey, the amount of grain consumed per capita per day obtained from calculation of food consumption was about 70 g more and the amount of animal food 18 g less. The intakes of energy and nutrients obtained from the two methods were different, but from animal sources showing about 4% higher in the latter. This suggested that the results from dietary survey was nearer to the actual status.The results indicated a tendency lying in the period of adjustment of food pattern. It also demonstrated the imbalance status for some nutrients intake.The difference of the food pattern and nutritional level between rural and urban was distinct and the difference also existed in intercountries. The health index of the inhabitants was better in the recent years but the correlation between the physical index and nutritional level hasn't been established yet.We suggested to increase animal food and beans intake properly, However the animal fat intake must be controlled. A goal was presented about the dietary pattern for the inhabitants in Jiangsu province in 2000. Various demands should de given according to the various area conditions.In addition, some discussion about the DDP score method has been made.
