Objective: To evaluate the usual fruit intake of Chinese adults.
Methods: 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.
Results: 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.
Conclusion: 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.
