上海居民膳食组成与疾病关系的探讨

Studies on Relationship between Dietary Composition and Diseases in Shanghai Population

The changes of the dietary composition of Shanghai population from 1950 to 1985 were investigated and the relationship between the dietary composition and the mortality of diseases of the population was analysed with retrospective method. The results showed that the amount of consumption of grain was decreased but that of animal foods increased (except that around 1960) year after year during the past 35 years. The consumption of meat and eggs in 1985 was 2.8 and 4.9 times , higher than that in 1950 respectively. The intake of carbohydrates was decreased but- that of fat increased year by year. The ratio of polyunsaturated fat to saturated fats (P/S) was decreased and there was a trend of excess intake of fat. The mortalities from malignant tumours, cardiovascular and cerebrovascular diseases were increased year by year, which correlated strongly with the consumption of dietary saturated fat. On the other hand the intake of protein, calcium and riboflavm was lower. Therefore, the dietary composition of Shanghai population was imperatively adjusted.
