To evaluate the usual fruit intake of Chinese adults.
A total of 12 379 adults aged 18 to 65 years old with both 3 days 24 hours dietary recall data and FFQ data were chosen from China Nutritional Transition Cohort Study( 2015). The models of fruit consumption probability and amount for Chinese adults were fitted using the National Cancer Institute method( referred to as NCI), to evaluate the fruit usual intake of Chinese adults, and to describe the distribution of the consumption.
According to 3 consecutive days of 24 hours dietary recall, the probability of consumption of fruit among Chinese adults was 40. 2%, the median of cosumption was 0( 0, 70. 0) g/d. The frequency of fruit consumption greater than or equal to once a day was17. 4% in male, which was lower than that of 22. 9% in female. According to the NCI method, the probability of fruit consumption among Chinese adults reached 98. 7%, the fruit consumption probability in male was 98. 3%, slightly lower than that of 99. 1% in female; the median of average daily consumption of fruit was 6. 4( 3. 2, 58. 3) g/d, it was4. 4( 2. 5, 36. 7) g/d in male, 9. 0( 4. 1, 78. 6) g/d in female.
Through the NCI method, the rate of consumption of fruit among Chinese adults has been greatly improved. And the distribution of fruit consumption has been somewhat improved, but was still on the low level, far away from the lowest recommended intake. Some measures should be taken to guide reasonable fruit consumption behavior among Chinese residents. Meanwhile, by combining the FFQ method with dietary recall method, separating the nonconsumers from the un-consumers, and taking into account the correlation between fruit consumption probability and amount, NCI method can reevaluate the usual intake of fruits.
评估中国成年人的水果通常摄入量。
从中国营养转型队列研究（2015年）中选取12379名年龄在18至65岁之间、同时拥有3天24小时膳食回顾数据和食物频率问卷（FFQ）数据的成年人。采用美国国立癌症研究所方法（简称NCI）拟合中国成年人水果消费概率和数量模型，以评估中国成年人的水果通常摄入量，并描述消费分布情况。
根据连续3天的24小时膳食回顾，中国成年人水果消费概率为40.2%，消费量中位数为0（0，70.0）克/天。水果消费频率大于或等于每天1次的男性为17.4%，低于女性的22.9%。根据NCI方法，中国成年人水果消费概率达到98.7%，男性水果消费概率为98.3%，略低于女性的99.1%；水果日均消费量中位数为6.4（3.2，58.3）克/天，男性为4.4（2.5，36.7）克/天，女性为9.0（4.1，78.6）克/天。
通过NCI方法，中国成年人水果消费率有了大幅提高。水果消费分布也有所改善，但仍处于较低水平，远低于最低推荐摄入量。应采取一些措施引导中国居民合理的水果消费行为。同时，通过将FFQ方法与膳食回顾方法相结合，区分非消费者和未回答者，并考虑水果消费概率与数量之间的相关性，NCI方法可以重新评估水果的通常摄入量。
